A low-down look at the QNX concept cars

Paul Leroux
It’s that time of year again. The QNX concept team has set the wheels in motion and started work on a brand new technology concept car, to be unveiled at CES 2016.

The principle behind our technology concept cars is simple in theory, but challenging in practice: Take a stock production vehicle off the dealer’s lot, mod it with new software and hardware, and create user experiences that make driving more connected, more enjoyable, and, in some cases, even safer.

It’s always fun to guess what kind of car the team will modify. But the real story lies in what they do with it. In recent years, they’ve implemented cloud-based diagnostics, engine sound enhancement, traffic sign recognition, collision warnings, speed alerts, natural voice recognition — the list goes on. There’s always a surprise or two, and I intend to keep it that way, so no hints about the new car until CES. ;-)

In the meantime, here is a retrospective of QNX technology concept cars, past and present. It’s #WheelWednesday, so instead of the usual eye candy, I’ve chosen images to suit the occasion. Enjoy.

The Maserati Quattroporte GTS
From the beginning, our technology concept cars have demonstrated how the QNX platform helps auto companies create connected (and compelling) user experiences. The Maserati, however, goes one step further. It shows how QNX can enable a seamless blend of infotainment and ADAS technologies to simplify driving tasks, warn of possible collisions, and enhance driver awareness. The car can even recommend an appropriate speed for upcoming curves. How cool is that?




The Mercedes CLA 45 AMG
By their very nature, technology concept cars have a short shelf life. The Mercedes, however, has defied the odds. It debuted in January 2014, but is still alive and well in Europe, and is about to be whisked off to an event in Dubai. The car features a multi-modal user experience that blends touch, voice, physical buttons, and a multi-function controller, enabling users to interact naturally with infotainment functions. The instrument cluster isn’t too shabby, either. It will even warn you to ease off the gas if you exceed the local speed limit.




The Bentley Continental GT
I dubbed our Bentley the “ultimate show-me car,” partially because that’s exactly what people would ask when you put them behind the wheel. The digital cluster was drop-dead gorgeous, but the head unit was the true pièce de résistance — an elegantly curved 17” high-definition display based on TI’s optical touch technology. And did I mention? The car’s voice rec system spoke with an English accent.




The Porsche 911 Carrera
Have you ever talked to a Porsche? Well, in this case, you could — and it would even talk back. We outfitted our 911 with cloud-based voice recognition (so you could control the nav system using natural language) and text-to-speech (so you could listen to incoming BBMs, emails, and text messages). But my favorite feature was one-touch Bluetooth pairing: you simply touched your phone to an NFC reader in the center console and, hey presto, the phone and car were automatically paired,




The Chevrolet Corvette
I have a confession to make: The Corvette is the only QNX technology concept car that I got to drive around the block. For some unfathomable reason, they never let me drive another one. Which is weird, because I saw the repair bill, and it wasn’t that much. In any case, the Corvette served as the platform for the very first QNX technology concept car, back in 2010. It included a reconfigurable instrument cluster and a smartphone-connected head unit — features that would become slicker and more sophisticated in our subsequent concept vehicles. My favorite feature: the reskinnable UI.




The Jeep Wrangler
Officially, the Wrangler serves as the QNX reference vehicle, demonstrating what the QNX CAR Platform can do out of the box. But it also does double-duty as a concept vehicle, showing how the QNX platform can help developers build leading-edge ADAS solutions. My favorite features: in-dash collision warnings and a fast-booting backup display.



Well, there you have it. In just a few months’ time, we will have the honor of introducing you to a brand new QNX technology concept car. Any guesses as to what the wheels will look like?

Developing safety-critical systems? This book is for you

In-depth volume covers development of systems under the IEC 61508, ISO 26262, EN 50128, and IEC 62304 standards

Paul Leroux
In June, I told you of an upcoming book by my colleague Chris Hobbs, who works as a software safety specialist here at QNX Software Systems. Well, I’m happy to say that the book is now available. It’s called Embedded Software Development for Safety-Critical Systems and it explores design practices for building medical devices, railway control systems, industrial control systems, and, of course, automotive ADAS devices.

The book:
  • covers the development of safety-critical systems under ISO 26262, IEC 61508, EN 50128, and IEC 62304
  • helps developers learn how to justify their work to external auditors
  • discusses the advantages and disadvantages of architectural and design practices recommended in the standards, including replication and diversification, anomaly detection, and so-called “safety bag” systems
  • examines the use of open-source components in safety-critical systems
Interested? I invite to you to visit the CRC Press website, where you can view the full Table of Contents and, of course, order the book.

Looking forward to getting my copy!

Econ Update: WREL Lexington VA

by Mike Smitka, Economics Dept, Washington and Lee University

Sept 17 (here) and Sept 24 (below)

The Fed – specifically the Federal Open Market Committee, comprised of the 12 presidents of the regional Federal Reserve banks and the five members of the Board of Governors – meet today, and will issue their press release at 2 pm. Even if they bump rates [they did not], "bump" is the operative term as any increase would be from 0% to 0.25% or 25 bp (basis points). Now 6 month rates have built into them a bump up to 0.5% by March 2016. In the past 12 months two year rates have really climbed – to 0.75%. [Laugh: sarcasm.] Keep going: 5 year rates, car loan territory, are at 1.5%. You have to get to 30 yrs (mortgage rate territory) to be above 3.0%. But those looking at long-term bonds don't have much to gain (or lose) by what the Fed announces tomorrow – they anticipate rates gradually rising, but over 30 years it matters little whether it occurs today or early next year. So don't expect those to move much, whichever way the FOMC votes. Remember, too, that rates jump around every day for a wide variety of reasons – so far this year 10 year and 30 year rates have averaged a bump up or down of 5 bp (.05 percentage points) each business day.

The August CPI is out. Now the CPI overstates inflation; more below. This month's release is more of the same, headline inflation is 0.2% from a year ago, and even if take out energy it's only 1.8%, both very low. The bottom line is no surprises, so I won't detail. But take a look yourself: you can go to the Bureau of Labor Statistics web site and have some fun. There's a huge amount of data to play with. There are 350 series just for beverages – what's been happening to beer? – and 283 series for medical items. Now medical costs were rising over 5% starting in the latter half of the 1960s, and have generally been well above the inflation average. So not only are we consuming more healthcare as our population ages and as medical technology improved, but we were paying more for it. Now 5+% adds up: we pay roughly twice as much as the rest of the developed world for similar treatments and services and drugs. So the past couple years have seen a real slowdown, to 2.5%. That's a bit above average, but certainly is very welcome. Anyway, look for fun items, the CPI aims to capture the top thousand or so categories of what we consume, enough that I always find things I've never thought of as significant, or indeed have never known existed!

Now the CPI overstates actual inflation, probably by 1%, and quite possibly more when inflation is low. One reason is that our economy is dynamic, with retailers coming and going. New retailers aren't sampled, the list of stores and online retailers from which the Bureau of Labor Statistics collects data can't be updated instantaneously. But new retailers offer some advantage – OK, some don't, but they don't last long. Well, the successful new retailers offer cheaper goods, or better goods for the same price, or greater convenience, or some other benefit. Likewise new goods don't show up immediately, and with a few exceptions items that truly are "new and improved" don't get counted as things that are effectively less expensive. Finally, we as consumers substitute from a good whose price has gone up (or not fallen) to one cheaper, think varieties of apples.

In addition, the "dynamic" aspect makes interpreting the CPI hard. We know that over the short run of a year or two energy prices move a lot. The recent drop in gasoline prices doesn't however directly affect the prices of other things we consume. Yes, it costs less for distributors to get their goods onto the shelves of a Kroger or Walmart, and it's also cheaper to run the freezers and vegetable coolers. But such stores don't change their prices for every short-run blip in energy prices.

So how do we know what's happening to inflation when prices of things such as energy and food are volatile? One answer is to look at inflation excluding such goods. Another is to create a sticky price index. The BLS plays around with several versions. One is a trimmed mean index, which cuts out the items that rise the most and fall the most. (That inflation measure is at its lowest for the last several months, at 1.2%.) Then there's the median rate, where half the goods are rising more, half less. That midpoint has been higher than the average. At 2.1%, it is still down from recent months. Then the BLS divides goods into ones whose historic prices are "sticky", seldom changing, from those that are "flexible", moving up or down in most months. The "sticky" rate at 1.9% over 3 months is likewise down from earlier this year. And we can look at sub-series: "sticky" less food and energy rose at the same 1.9%. Remove shelter and it's lower, at 0.4%, and again trending down. Not surprisingly, given the drop in gas prices, the flexible rate is low and trending down even more.

None of us are exactly average, either: we don't consume ever item the CPI measures, much less consume them in the same proportion as the mythical average American. More on Sept 24th on the experimental CPI for older Americans (age 62 and above).

Sept 24th: just bullet points, not proper prose
  • New Residential Sales out later today – that is, after I record but before this airs. local sales moribund, no one looking. but we're not average. However, New Residential Construction data released a week ago showed a decline
  • Oil: both Cushing OK and Brent (Europe) at $47, except for a brief trough in 2009, ultra-low sulfur at lowest in the 10 years for which I have data
  • The Fed (I): they have to work from data on what's happened, whereas what they do affects the economy over the coming 18-24 months. So inevitably it's a judgement call. With inflation low, there's no harm on waiting – they next meet Oct 27th, and then again Dec 15th. In the early post-WWII era Milton Friedman and others had hoped to find rules that would work, but he gave up and by the late 1960s didn't talk about that when he spoke to other economists in professional gatherings. Our economy is simply too dynamic. So what the Fed does remains a judgement call. As we know, local real estate markets are moribund. But is that representative? Those gathered around the Fed's (very) large table listen to qualitative reports from each of the 12 regional banks – multiple regions because the Fed was set up before we had a national financial system. Anyway, part of the job of the regional Feds is to talk to people and businesses in their district, how many homes are realtors showing relative to last year, foot traffic at retailers, new malls doing well or poorly, the local cement plant booking orders or not. That feeds into the formal data that I routinely talk about.
  • The Fed (II): caught some by surprise, short-term rates (6 m/s) had risen, but since it will be 6 weeks before the FOMC again meets, then that will be delayed by at least 1½ months. the amount of money people expect to be able to earn over 6 months is now lower by at least ¼ and so bond prices shifted. but at long maturities nothing happened: 6 weeks over the life of a 30 year bond is no big deal. rates 0.24% but fell to 0.11%. 11 bp. 1 year 10 bp. 20 year 8 bp. 30 year 6 bp. and if you're thinking about buying a house it's the LR you care about.
  • Experimental CPI for age 62 and above: different weights in consumption. up 0.6% over a year ago. medical care rising 5% in early 2000s, rate slowed during Great Recession to 3%, lowest sustained rate, but then fell further in early 2013. ACA hasn't resulted in a jump. [did not talk about on the radio
  • [topic brought up by Jim Bresnahan] China: most commentators don't follow China, no one has the time to follow everything. but no surprise that growth is lower, it's been slowing for years. the working age population in China is falling, they've finished their national superhighway system – and it's new, so no maintenance costs – and so on. Yes, there was a blip due to their successful 2009 stimulus package – they didn't suffer from a recession, unlike the US and Europe and Japan – so that helped hide the trend. Anyway, while China is big, it's still only a bit over 10% of global trade, and trade is 10% of the US economy, and their imports from the US are merely slowing (say, 10%), and it's only a share of US exports, say 10%. So the impact is 10% of 10% of 10% of 10%, or 0.01%. Now there are feedback effects that mean the impact is bigger, but it's still likely less than the normal volatility of US growth.
  • [topic brought up by Jim Bresnahan] Debt ceiling shutdown threat: this is really a political question, Congressman grandstanding for one or another reason. If you listen to the news, you've not heard much about deficits, none of the scare-mongering of 2009 – and for good reason. Deficits balloon during recessions, and more during deep recessions, and our Great Recession was a doozy. Tax receipts fall, people lose their jobs and collect unemployment insurance and medicaid, and older workers decide to start receiving social security sooner rather than later. Well, tax receipts are back up, unemployment claims are way down, and the budget deficit is now much, much smaller. No crisis. There are long-term issues, but that's not what happens in an election cycle.
  • United Way of Rockbridge: our campaign starts Friday, the banner is up over Main Street in Lexington (we don't have one for Buena Vista – but they tap programs we fund roughly proportional to their population, we serve the entire Rockbridge area).

From ADAS to autonomous

A new webinar on how autonomous driving technologies will affect embedded software — and vice versa

Paul Leroux
When, exactly, will production cars become fully autonomous? And when will they become affordable to the average Jane or Joe? Good questions both, but in the meantime, the auto industry isn’t twiddling its collective thumbs. It’s already starting to build a more autonomous future through active-control systems that can avoid accidents (e.g. automated emergency braking) and handle everyday driving tasks (e.g. adaptive cruise control).

These systems rely on software to do their job, and that reliance will grow as the systems become more sophisticated and cars become more fully autonomous. This trend, in turn, will place enormous pressure on how the software is designed, developed, and maintained. Safety, in particular, must be front and center at every stage of development.

Which brings me to a new webinar from my inestimable colleague, Kerry Johnson. Titled “The Role of a Software Platform When Transitioning from ADAS to Autonomous Driving,” the webinar will examine:
  • the emergence of high-performance systems-on-chip that target ADAS and autonomous vehicle applications
  • the impact of increasing system integration and autonomous technologies on embedded software
  • the need for functional safety standards such as ISO 26262
  • the emergence of pre-certified products as part of the solution to address safety challenges
  • the role of a software platform to support the evolution from ADAS to autonomous driving

If you are tasked with either developing or sourcing software for functional safety systems in passenger vehicles, this webinar is for you. Here are the coordinates:

Electric Cars: Renault's the Leader, not Tesla!

by Mike Smitka
During the GERPISA auto conference in Paris in June I stayed in a hotel with a row of electric vehicles parked out front. The "Bluecar" wasn't fancy, but they were used: at times all slots were full, at others none were parked there. I don't know whether the company involved, Autolib', is doing well. But the point is that in parts of Europe a sizable part of the population sees electric cars, day-in and day-out. In Norway, they're 17% of the cars on the road, despite the challenge that batteries face in a low ambient temperature environment.
Within the electric car market the clear leader is the Renault-Nissan alliance, not Tesla. On a worldwide basis they now have over 250,000 vehicles on the road. What is most interesting are the components of Renault's business model.
First, Renault is launching multiple vehicles. Their best seller is the ZOE, made on the same assembly line as the Clio. In other words, they are not needing to design a whole new vehicle, and are gradually leveraging their multiple platforms. (They also have the Kangoo light commercial van.) With this experience in hand they are now ready to launch additional electric vehicles in short order, of course subject to demand.

Kangoo, Paris June 2015
Second, while they sell the vehicle, they lease the battery pack, at a price that is a function of the amount of recharging. That lowers the ZOE's out-the-door price to a level that is higher than the Clio, but not prohibitive. Furthermore, it means that purchasers need not worry about their vehicle quickly becoming obsolete, because Renault designed the battery packs to be both modular and easily replaced. Renault will re-use the overall pack and recycle the individual battery units. At the end of your battery lease, you just lease a new one, and in the process benefit from intervening technology upgrades without need for a new car.
I test drove both the ZOE and the Kangoo on Paris streets, as well as the Twizy quadricycle. I'm not sure what market the latter is targeting, but it doesn't get classed as a car so taxes, drivers licenses and all that are marks in its favor. The version I drove, however, did not have windows and was otherwise ... odd.
ZOE, Paris, June 2015
The ZOE and the Kangoo, however, were proper vehicles, with a refined ride and a refined interior. Other than being slightly quieter than their sister gasoline- and diesel-engine counterparts, you're not really aware of a difference. Yes, there's range anxiety. But a couple of the staff with whom we met use the ZOE as their primary commute. With rapid charging stations more and more common around Paris in particular and France in general, that's less of an issue than it might seem. While a full charge take an amount of time unacceptable for someone running errands that stretch its range, getting to 60% charge doesn't take long, particularly if the comparison is an American running into the gas station convenience store to pick up a soda and a snack. You might need to make more stops than otherwise on a drive to the beach, but time charging is not prohibitive. (You can apparently contract to use the Autolib' slots, which gives you a great parking spot as part of the deal.)
Now with today's low petroleum prices, full battery electric cars aren't cost competitive. Battery prices however keep falling, and since even Saudi Arabia uses secondary recovery methods to extract petroleum, gas prices (diesel in France!) won't stay low indefinitely. Furthermore, even today, charging off-peak in France is no more expensive than running a car on diesel. So with a charging network that is improving daily, the key (as it always has been) is the up-front cost of batteries.
When that time comes, it will be Nissan and Renault that will change the industry, not Tesla. Their vehicles will be at a price point solidly in the mass market, they will be able to offer an array of vehicles, they will have a dense global network of dealers (and hence repair shops) that will be able to handle trade-ins and finance, and manufacturing capacity won't be an issue, because the alliance is making sure that its BEVs can be mixed with existing "conventional" vehicles on existing assembly lines at normal line speed.
To reiterate, at that point Tesla won't even be in the game.
[I have pages of notes from my June 2015 test drive and associated meetings with Renault executives, and may insert the specifics for vehicle purchase and battery lease. As a start, however, I believe the qualitative case is sufficient to make my point.]

Reconsidering China: An Essay

by James Vena | Jun 3, 2014 | Essays |

posted by David Ruggles

Co-blogger Mike Smitka (住老师 in his China class) comments at the end.
He's also edited out typos, filled in dates and so on using [italics].

In light of recent events some might be interested in what this China expert had to say over a year ago. He speaks as someone who has done business there for decades. Ruggles

Have China’s “growing pains” manifested into something a bit more troubling relative to its growth, internally and externally?

My first visits to Asia & China (on business) were in the early-mid 1980’s and things were obviously much different back then. Aside from being much more socially oppressed and isolated, the most glaring difference was in its local economy, as all business was nationalized.

All companies were State Owned [Enterprises] (SOE), hence government run and managed. At that time, workers were essentially “drones”, displaying very little in the way of desire or change, at least externally (or risk re-education to curtail selfish dreams of bourgeois capitalism). ["State" includes enterprises controlled by provincial, prefectural, urban, town and village governments – the latter by the early 1980s were already dynamic, in contrast to the much smaller number controlled by the central government that fell under the national planning framework.] In those days, international trade and foreign investment in the People’s Republic of China was in its embryonic stage. Many corporations, especially from the USA, overlooked the isolationism, as they were seduced by the [potential] size of the new market.

Many of these corporations entered China with reckless abandon, making bad deals that ultimately often resulted in huge financial losses that wrote off as “investments”. It was fairly standard for US and other foreign companies, to have the end products sold in “friendship shops” and other local stores, to Chinese consumers using only the local RMB. Of course, it was illegal to convert RMB to FEC (foreign exchange certificates), and since the RMB was not convertible, with strict conversion restrictions in place for JV’s, foreign corporations were holding “paper” that was devaluing on a monthly basis. Rather than fret over these embarrassing losses, most companies chalked it up as “tuition paid”. While it came as no surprise that this sort of control over the economy and its people would make it difficult to believe that things would ever change, most stayed in the game, fearing to miss out on selling the proverbial “toothbrush” to billions of new customers. [In the end some of these companies have done very, very well!]

I saw things a bit differently. Perhaps it was due to my young and hopeful demeanor, but I saw beyond the Mao suits. Being young at the time, I was fortunate enough to be exposed to the industrious and driven, younger generation, that seemed to share my spirit of unrefined entrepreneurism. Most of the people that I met in those days that were my age (mid 20’s to 30 some-things) had a very similar thirst for knowledge with a shared intellectual humility. Clearly a trait that the older generation didn’t possess as part of their understandably arrogant nature.

I remember, that the mid to late 80’s, just prior to the Tiananmen Square incident, this younger generation aspired to become rich, educated and desired a glorious, western lifestyle [that echoes the "rich and glorious" phrase the government used to tout the reform policies of that era]. During one of my visits in 1987 to Lanzhou (Gansu province) on a joint venture project with the local oil refinery (Sinopec), I recall being taunted with signs that were derogatory to western culture during the so called "down with bourgeois capitalism" campaign.

My recollection however was the noticeable embarrassment on the faces of the younger people in the delegation, not just for me, but for themselves and the abrasive behavior towards the Western cultures displayed by their elders. The younger they were, the less they agreed with the propaganda, in spite of living under the threat of a re-education process that most just didn’t even know of, outside the walls of the PRC. [That threat was real under Mao, but he died in 1976. It took quite some time for Chinese to realize that the mass persecutions of old weren't going to be revived. Under Mao it was imperative for your health to heed to the propaganda, even if you didn't believe it.]

Now, so many years later, as those people, of that generation, particularly living in the coastal cities found the glorious road to wealth, I started to question whether China, if need be, would ever be able to slow down its economy enough to stop it from one day spiraling out of control, without creating a breeding ground for social and civil unrest. While many things have changed aesthetically, the reality is that most still believe that the government of China can suppress the animus from the masses if ever needed.

I am not so sure! [Nor is the government so sure!]

Surely there will not be a "Great Leap Forward II" [the GLF was 1958-60], as the next Cultural Revolution [the Great Proletariat Cultural Revolution (CR) was 1966-76] will be the result of a widening wealth and freedom gap which will one day force the outright call for democracy.

After all, despite all of its economic achievements, China is not a democracy. [More a plutocracy?? – and hence closer politically to the US than we might assume??] Recently, learning that China had clamped down on LinkedIn, Google and other internet sites in light of the 25 year anniversary of Tiananmen Square brought back some mixed feelings and an eerie “deja vu” type memory. [Actually, they blew their attempt to dominate the market in China over a decade ago due to technology arrogance, and aren't a force there.]

It is hard to believe that its been a quarter century since the massacre at the Square took place [in 1989]. Being someone that was quite active in China, at a “liaison office” in Beijing during that time, it still remains a bad (and sad) memory. Blocking internet sites and oppressing the views of the people, seems to hearken the old adage that the more things change, the more they stay the same. As I stated earlier, while many things have changed aesthetically, the reality is that most still believe that the government of China can suppress the animus from the masses if ever needed. After reading the dozens of news feeds and stories about the clampdown, its clear that many things haven’t changed. [But some things have: there's no hint of the mass political campaigns with the purging of millions that took place under Mao. Today the Party wears a "velvet glove", though individuals who openly push the limit are asking for trouble, and frequently find it.]

Going forward, I’ve been most concerned about the mounting internal pressures of discontent, along with a growing list of external tensions that have manifested over the last two years. In my view, we should all be concerned that the headwinds that have been burdening China are now becoming a bit more than the widely forecasted growing pains that are systemic. The widening wealth gap, business opportunities and access to the finer things, between those who live on the coastal areas versus those who line inland, is troubling. Many, who reside inland, are patiently awaiting the wave of capitalization and the "gloriousness" of becoming wealthy.

For some time now the central bank [the People's Bank of China] has been “threading the needle”, knowing that out-of-control inflation and an overheating economy will surely cause unrest in the inland cities, but anemic growth will create economic harm to a very overrated economy. One must remember that the first and most important concern for China, is its own domestic stability and security. If the people start to lose confidence in its leadership, all hell will break loose.

When I was in China during 1989, I saw first hand how quickly things can get emotionally driven and spiral out of control. Currently I’ve been most concerned about the mounting internal pressures along with a growing list of external tensions that have manifested over the last two years. The interior of the country, which is more than half of its population, have actually suffered because of the” new age” capitalism. Despite the storied and highly publicized new billionaires of modern China, over two thirds of China’s citizens earn less than the average wage of citizens living in some of the poorest countries in the world. This is not really surprising, as China has seen such growth, mainly via global trade, create this same effect of rich and poor, coastal versus interior cities and a wealth gap several times in last few centuries. Further, as I stated, China would have to very carefully “thread the needle” to slow down growth enough to not allow runaway inflation to completely annihilate the non-coastal citizens, before they have a drink from the well of the “new age” capitalism. [I'm not sure when – the coastal export economy was very small until the 1990s. The old "China Trade" was small volumes of luxury products, modest amounts of tea and porcelain and the like – enough to keep the British East India Company afloat but not enough to lift China's boat.]

As I wrote in an earlier op-ed, a move to allow the Yuan to freely float prematurely, would have further widened the wealth gap between the citizens in the coastal and non-coastal cities. This would surely lead to civil unrest, of devastating proportions. Making sure this doesn’t happen is China’s primary concern. So a policy to insure that the government does not lose the confidence of its people is a very real story. Remember, Mao exploited these same tensions in the Long March into the interior to form an army of the poor, to ultimately fight and defeat the rich and powerful in the coastal regions. Of course, the long term effect on China did not end so happily.

Mao’s conquering though division, manifested into an isolationist society shut off from the international trade ecosystem, that China previously exploited for its benefit. Isolationism led China to close the wealth gap, which in turn, left them equally downtrodden, hungry and very poor. The government, must convince the people that this will not happen again. China is not a democracy, so confidence is paramount to internal security.

My sources tell me that, even in light of the recent coup d’état (a very organized and covered up one that most don’t know much about [indeed], most in China are still confident that their government is leading them into the right direction. Nevertheless, the concerns are justified, and I caution that most of my sources are from SOE’s, and private JV’s, mostly in the coastal cities that have something now to lose.

Now, a few years after my original report where I pointed out that China cannot continue to grow at the unprecedented rates, without having a labor problem, many balked at my original statement that labor was getting expensive in the major cities and labor shortages were a real concern. [Isn't that a good thing??? – unless of course you're the owner of an export business built on exploiting cheap labor and not on gradually improving your product and your productivity? To rephrase: fighting this shift is tantamount to trying to keep people poor.]

Well, once you stop listening to all of the politically motivated bashing, particularly being spewed by US politicians and their drone-like constituencies, you’ll discover that the cheap labor in China for the most part is gone. Factories are now trying to move inland, and the empty infrastructures are beginning to fill. This will be a process, but as growth slows, and manufacturing is moved inland, caution, concern and vigilance will be needed by Beijing, as problems could arise and another Coup attempt (this one will be harder to cover up) may erupt if the people living inland lose patience and confidence in its government. Remember, China, is not a democracy. [Would being a democracy make such tensions easier to handle? Changing the politicians won't change the underlying economic tensions!]

The stewardship of China’s economic leadership deserve a lot of credit for threading this proverbial needle. It’s still too early to tell, but knowing this is their main concern is a great step towards interior stability. This shift away from the expensive manufacturing costs in the major coastal cities is creating a boon in many Southeast Asian countries that are now being sought as an alternative to China’s high labor costs.

It is important to point out, that while this may be welcome news to manufacturing communities in the world, China uses private savings of its citizens to finance its industrial infrastructure. Dwindling exports cannot be a sustainable phenomenon and will ultimately cripple domestic consumption. This will not be good for those who are hoping to take advantage of the new export markets they are finding in China. [Why should "dwindle" lead to a balance of payments crisis?] Remember, China’s industrial production is designed to be larger than its domestic economy can take up. China must export to finance their import of raw materials. It’s a two edged sword, but China must have a policy in place that insures demand for its exports. China now is doing this by methodically investing money in the economies of consumer countries. [How does buying a US company insure demand for exports from China?? – those are not the sort of firms that Chinese moguls target!]

You now see China moving eggs from its US basket to other nations as a means of diversification. Many would like you to think that they are making a political statement or trying to blatantly manipulate foreign currencies. It’s simply a matter of planning the future to ensure access to a growing global marketplace. [Data on such purported diversification are weak, plus we don't see US bonds crashing. If you check the data, China trades more with Europe than with the US, so of course they hold lots of Euros.]

The economic downturn in the USA and debt crisis in Europe at the end of the last decade created a decrease in trade to both of these major trade partners, while not being able to appropriately increase domestic demand in order to take up the slack, due to the “two thirds” not being economically able to do so. Compounding its concern is the fact that the coastal populations with the wealth depend on exports. The impoverished interior requires subsidies that will become a burden to provide if global economic growth slows to a crawl.

China also finds itself with a need to protect itself militarily. Issues in Tibet, trouble on the border with India, and the continued calls by the USA to interrupt China’s foreign trade has left China in a position that it needs to consider protecting itself. It wouldn’t take much for the USA to cut off China’s access to the sea-lanes of trade. US politicians are doing too much saber rattling for China to just write off this possibility. China is simply reacting to what the USA is capable of, in a day and age where the China bashing is at monstrous proportions.

In a nutshell, China will continue to have growing pains, will continue to have escalating labor costs, will continue to engage in their plans to narrow the wealth gap by moving factories inland, will continue to invest in other countries, continue to diversify those investments and will continue to understand that the problems they face are not understood by so many of its critics and pundits. [This implicitly assumes that Chinese political leaders understand their own problems. Is that really credible? Is it policy acumen that gets you the widespread support of enough of the 80 million members of the Chinese Communist Party to ascend into the top leadership? Or do would-be Chinese leaders in fact run election campaigns, financed by large amounts of money, that might put end up with the wrong people rising to the top?]

China revised its forecast downward just one half of one percent yesterday and the markets reacted negatively (other headwinds notwithstanding). Can you imagine the inflationary pressures and collapsing debt and monetary markets if China faced an out of control civil uprising? The thought frightens me, and is only eclipsed by my fear that many who don’t understand modern China or its history are calling for changes and creating the fear that will surely increase the odds that such a catastrophe can happen. The fragile thread that China is holding needs less not more pressure.

Recently, the CBOC insinuated that an end to the appreciation of the yuan was going to be a necessity, for at least the time being. [See Smitka's Aug 18th post on on the yuan on this blog here.] The FT stated “Top Chinese central bank officials on Monday said China’s huge trade deficit in February showed that the value of its currency was close to equilibrium after more than six years of gradual appreciation. This trade deficit is a positive sign that the renminbi [yuan] exchange rate is close to its equilibrium level,” Yi Gang, deputy central bank governor, said at the National People’s Congress, the annual session of China’s rubber-stamp parliament.

China has had some surprising deficits in trade over the last few months. Rising imports of commodities helped drive the change, from trade surpluses, and rising labor costs, hurt exports. The end of cheap labor in China is no longer a prediction but a reality. The shift towards looking to China as a consumer of imports has also manifested due to the rising labor costs and fatter wallets for those who live in the coastal cities. “On March 5th Standard Chartered, an investment bank, released a survey of over 200 Hong Kong-based manufacturers operating in the Pearl River Delta. It found that wages have already risen by 10% this year. Foxconn, a Taiwanese contract manufacturer that makes Apple’s iPads (and much more besides) in Shenzhen, put up salaries by 16-25% last month,” according to a an article written in the Economist.

“It’s not cheap like it used to be,” laments Dale Weathington of Kolcraft, an American firm that uses contract manufacturers to make prams in southern China. Labour costs have surged by 20% a year for the past four years, he grumbles. China’s coastal provinces are losing their power to suck workers out of the hinterland. These migrant workers often go home during the Chinese New Year break. In previous years 95% of Mr. Weathington’s staff returned. This year only 85% did. (Last year, my friend Shaun Rein, wrote a book called “The End of Cheap China” and I highly recommend it to those who are curious and affected by this shift.)

Kolcraft’s experience is typical. When the American Chamber of Commerce in Shanghai asked its members recently about their biggest challenges, 91% mentioned “rising costs”. Corruption and piracy were far behind. Labour costs (including benefits) for blue-collar workers in Guangdong rose by 12% a year, in dollar terms, from 2002 to 2009; in Shanghai, 14% a year. Roland Berger, a consultancy, reckons the comparable figure was only 8% in the Philippines and 1% in Mexico.”

The Yuan has appreciated by nearly 8% against the dollar since the Chinese government allowed it to begin rising again in 2010. It is up about 24% against the dollar since 2005. The most recent Big Mac index indicates that the yuan may be undervalued against the dollar by some 40%.” When The Economist computed the index differently last summer, in order to take account of variations in per capita income across countries, it found that the yuan was close to fair value. China continues to run large surpluses with America (though America exported over $100 billion in goods to China for the first time in 2011). More balanced trade overall and a sharp reduction in the growth of its foreign-exchange reserves suggest that China’s currency may be a lot closer to the “right” level than American politicians would like to hear.

Because of these changes, China is freeing up finances, expanding its manufacturing sector inland, and doing all of the diligent things that I wrote about here in this post. We should recognize and embrace the ideas of China, who is being much more proactive, than the USA was in 2007, when trouble was on the horizon. This opinion by Jeffrey Frankel written in Project Syndicate [no link provided] furthers some of my points. “China watchers are waiting to see whether the country has engineered a soft landing, cooling down an overheating economy and achieving a more sustainable rate of growth, or whether Asia’s dragon will crash to earth, as others in the neighborhood have before it. But some, particularly American politicians in this presidential election year, focus on only one thing: China’s trade balance

True, not long ago the renminbi was substantially undervalued, and China’s trade surpluses were very large. That situation is changing. Forces of adjustment are at work in the Chinese economy, so foreign perceptions need to adjust as well. China’s trade surplus peaked at $300 billion in 2008, and has been declining ever since. (Indeed, official data showed a $31 billion deficit in February, the largest since 1998.) It is clear what has happened. Ever since China rejoined the global economy three decades ago, its trading partners have been snapping up its manufacturing exports, because low Chinese wages made them super-competitive. But, in recent years, relative prices have adjusted.

The change can be measured by real exchange-rate appreciation, which consists partly in nominal renminbi appreciation against the dollar, and partly in Chinese inflation. China’s government should have let more of the real appreciation take the form of nominal appreciation (dollars per renminbi). But, because it did not, it has shown up as inflation instead. The natural price-adjustment process was delayed. First, the authorities intervened in 1995-2005, and again in 2008-2010, to keep the dollar exchange rate virtually fixed. Second, workers in China’s increasingly productive coastal factories were not paid their full value (the economy has not completed its transition from Mao to market, after all). As a result, China continued to undersell the world.” [Of course US workers are all paid their "full value" and CEOs earn their high incomes by being hundreds of times better than mid-level managers.]

But then the renminbi was finally allowed to appreciate against the dollar – by about 25% cumulatively during 2005-2008 and 2010-2011. Moreover labor shortages began to appear, and Chinese workers began to win rapid wage increases. Beijing, Shenzhen, and Shanghai raised their minimum wages sharply in the last three years – by 22% on average in 2010 and 2011. Meanwhile another cost of business, land prices, rose even more rapidly. As costs rise in China’s coastal provinces, several types of adjustment are taking place. Some manufacturing is migrating inland, where wages and land prices are still relatively low, and some export operations are shifting to countries like Vietnam, where they are lower still. Moreover, Chinese companies are beginning to automate, substituting capital for labor, and are producing more sophisticated goods, following the path blazed by Japan, Korea, and other Asian countries in the “flying geese” formation.” Finally, multinational companies that had moved some operations to China from the United States or other high-wage countries are now moving back. Productivity is still higher in the US, after all.”

Like certain other aspects of the US-China economic relationship, China’s adjustment is reminiscent of Japan with a 30-year lag. Japan’s trade balance fell into deficit in 2011, for the first time since 1980. Special factors have played a role in the last year, including high oil prices and the effects of the March 2011 tsunami. But the downward trend in the trade balance is clear. Even the current account showed a deficit in January. This development has received relatively little attention in the US and other trading partners, which is curious, given that, two decades ago, Japan’s big trade surplus was the subject of intense focus and worry – just like China’s now. At the time, some influential commentators warned that the Japanese had discovered a superior economic model, featuring strategic trade policy (among other attractions), and that the rest of us had better emulate them. Either that, or the Japanese were “cheating,” in which case we needed to stop them.

Most economists rejected these “revisionist” views, and argued that Japan’s current-account surplus was large because its national saving rate was high, which reflected demographics, not cultural differences or government policies. The Japanese population was relatively young, compared to other advanced economies, but was rapidly aging, owing to a declining birth rate since the 1940’s and rising longevity. That view has been vindicated. In 1980, 9% of Japan’s population was 65 or older; now the ratio is more than 23%, one of the highest in the world. As a consequence, Japanese citizens who 30 years ago were saving for their retirement are now dissaving, precisely as economic theory predicted. As the national saving rate has come down, so has the current-account surplus. China faces a similar demographic trend, and also a push to unleash household consumption in order to sustain GDP growth. As in Japan, the downward trend in China’s saving rate will show up in its current account. The laws of international economics still apply. [In my China class I've taught about demographic dividends and other links between demographics and the economy for many, many years. See syllabi and reading lists on the course web site!]

Today, China faces challenges to many interests, and in my view, a real and too big to cover up and contain coup d’état cannot be completely ruled out. The effects on the global economy will be akin to a financial Armageddon. I was there and a victim in business of the 1989 Tianamen Square incident. Business stopped and money didn’t flow for a long time. And that was a time that China was in its embryonic stages of being an important factory to the world, with prospects of being the largest economy in the world and new dictators of consumerism.

In addition, two of China’s buffer regions are in turmoil. Elements within Tibet and Xinjiang adamantly resist Han Chinese occupation. China understands that the loss of these regions could pose severe threats to China’s security, particularly if such losses would draw India north of the Himalayas or create a radical Islamic regime in Xinjiang. The situation in Tibet is potentially the most troubling. [For the Tibetans, not for China – Tibet is remote and sparsely populated.]

Outright war between India and China — anything beyond minor skirmishes — is impossible so long as both are separated by the Himalayas. Neither side could logistically sustain large-scale multi-divisional warfare in that terrain. But China and India could threaten one another if they were to cross the Himalayas and establish a military presence on the either side of the mountain chain. [That doesn't change the logistics! Nor is there current saber-rattling to suggest anyone pay attention to such scenarios.] For India, the threat would emerge if Chinese forces entered Pakistan in large numbers. For China, the threat would occur if large numbers of Indian troops entered Tibet.

China therefore constantly postures as if it were going to send large numbers of forces into Pakistan, but in the end, the Pakistanis have no interest in de facto Chinese occupation — even if the occupation were directed against India. Likewise, the Chinese are not interested in undertaking security operations in Pakistan. The Indians have little interest in sending forces into Tibet in the event of a Tibetan revolution. For India, an independent Tibet without Chinese forces would be interesting, but a Tibet where the Indians would have to commit significant forces would not be. As much as the Tibetans represent a problem for China, the problem is manageable Tibetan insurgents might receive some minimal encouragement and support from India, but not to a degree that would threaten Chinese control.

The key for China is maintaining interior stability. If this portion of Han China destabilizes, control of the buffers becomes impossible. Maintaining interior stability requires the transfer of resources, which in turn requires the continued robust growth of the Chinese coastal economy to generate the capital to transfer inland. [Huh? – the Tibetans are not "Han".]

Should exports stop flowing out and raw materials in, incomes in the interior would quickly fall to politically explosive levels. (China today is far from revolution, but social tensions are increasing, and China must use its security apparatus and the People’s Liberation Army to control these tensions). Maintaining those flows is a considerable challenge.

The very model of employment and market share over profitability misallocates scores of resources and breaks the normally self-regulating link between supply and demand. One of the more disruptive results is inflation, which alternatively raises the costs of subsidizing the interior while eroding China’s competitiveness with other low-cost global exporters For the Chinese, this represents a strategic challenge, a challenge that can only be countered by increasing the profitability on Chinese economic activity. This is nearly impossible for low value-added producers.

The solution is to begin manufacturing higher value-added products (fewer shoes, more cars), but this necessitates a different sort of work force, one with years more education and training than the average Chinese coastal inhabitant, much less someone from the interior. It also requires direct competition with the well-established economies of Japan, Germany and the United States.

Military issues are now at the forefront of Sino – US relations. China depends on the high seas to survive. The configuration of the South China Sea and the East China Sea render China relatively easy to blockade. The East China Sea is enclosed on a line from Korea to Japan to Taiwan, with a string of islands between Japan and Taiwan. The South China Sea is even more enclosed on a line from Taiwan to the Philippines, and from Indonesia to Singapore.

Beijing’s single greatest strategic concern is that the United States would impose a blockade on China, not by positioning its 7th Fleet inside the two island barriers but outside them. From there, the United States could compel China to send its naval forces far away from the mainland to force an opening — and encounter U.S. warships — and still be able to close off China’s exits. China simply doesn’t have a navy capable of challenging the United States. China is still in the process of completing its first aircraft carrier; indeed, its navy is insufficient in size and quality to challenge the United States. But naval hardware is not China’s greatest challenge. The Chinese have never had a carrier battle group in the first place, and there has been little reason to have one, as China in its more than 4000 years of documented history, has never attacked or tried to occupy another nation. [Uh, by sea – and even then this ignores China's takeover of Taiwan in the 1720s, as it had not previously been a part of the Ming empire. But China was unable to muster effective resistance to the British and Japanese navies in the 19th century, and unable to cross the narrow straights when Mao's military opponent fled to Taiwan in 1949. ]

The primary tenets of the Chinese thinking are Taoism, Confucianism and Legalism, which demonstrate that China really has no need nor historical precedent to be an aggressor or military power. [Uh, how then did "China" expand from a small section of the Yellow River plain to become a continental-sized empire? How then Tibet and Xinjiang, both 18th century additions by the Qing? How did Chinese troops end up fighting well inside Vietnam in 1979 (and getting kicked out, tails between their legs)?]

That said, China understands this may now be a problem and has chosen a different strategy to deter a U.S. naval blockade: anti-ship missiles capable of engaging and perhaps penetrating U.S. carrier defensive systems, along with a substantial submarine presence. The United States has no desire to engage the Chinese at all, but were this to change, the Chinese response would be fraught with difficulty. [If not for China, where else could we find an enemy that would justify keeping a large navy?]

China is therefore supplementing this strategy by acquiring port access in countries in the Indian Ocean and outside the South China Sea arena. Beijing already has financed and developed port access to Gwadar in Pakistan, Colombo and Hambantota in Sri Lanka, Chittagong in Bangladesh, and it has hopes for a deep-water port at Sittwe, Myanmar. In order for this strategy to work, China needs transportation infrastructure linking China to the ports. This means extensive rail and road systems, which will be difficult at best in many areas in the ASEAN region.

A bigger problem for china nowadays stems from internal security. The People’s Liberation Army (PLA) is primarily configured as a domestic security force – a necessity because of China’s history of internal tensions. It is not a question of whether China is currently experiencing such tensions; it is a question of possibility. Prudent strategic planning requires building forces to deal with worst-case situations. Having been designed for internal security, the PLA is by doctrine and logistically disinclined toward offensive operations. [This is a stretch. The big threat was an invasion from the steppes, as had happened many times over the centuries. Specifically, this meant defense against the USSR. Indeed, the two countries effectively broke relations in 1959 and fought a brief border war in 1969.]

China must present itself as an essential part of U.S. economic life, but today if you listen to US politicos speak, it is evident that most do not necessarily see China’s economic activity as beneficial. I for one see that in many ways China has been beneficial as the “factory to the world” and will move to the “consumers of the world” which will be equally beneficial to the global economy. As a matter of fact, I argue that China, saved the world's economy in 2008. Now, if the rest of the world, doesn’t recognize how fragile the internal structure of China will become if the citizens lose confidence, and the next coup isn’t thwarted, I think that we will all find out the hard way of how important and politically stable and financially viable China is, to world economy.

Mike Smitka: I have few objections to the overall economic picture above; I could quibble at length over the details. On the politics, there certainly are tensions, but these tensions have existed for three decades, and since 1989 and Tiananmen there has been no effective opposition. If China moved towards a representative system (whatever form such democracy might take), then there is the potential for a demagogue to use a leadership position to organize the masses as a base of support. Short of that how, precisely, would unhappiness be mobilized into political change? Indeed, is unhappiness greater now than in the past? Talking to business leaders is certainly NOT the way to find out. Finally, the picture of Chinese foreign policy initiatives may be current (but incomplete without mention of "nine-dotted-lines"). The attempt to place them in historical context, and hence to judge their motives and magnitude, is not done well.

Generational War: Do Older Worker Squeeze Today's Young Out of Jobs? Weekly WREL Radio Show

Click on Figures to enlarge!
Figure 1

Mike Smitka

I generally focus on the medium-run picture of the US labor market, the recovery process from the Great Recession. (Here is an example from this blog, replete with graphs.) As noted last week, my analysis shows we're on track to reach "normalcy" in 2018, assuming various headwinds don't slow us down. That's also the bottom line of the latest July 2015 IMF Article IV review of the US economy: we still have lots of excess capacity, in this case people who would like a full-time job but either have stopped looking on a regular basis (and hence are not counted as "unemployed") or are on involuntary short hours.

To track that, I look at participation. Those data do show a drop in prime-age labor force participation consequent to the Great Recession, a topic I'll return to that later this fall, since it's an analysis I'll use at some point in my Fall 2015 classes. Two longer-term changes jump out of the data, my topic in this post. One is the rise in the share of older Americans at work over the past 20 years (the Bureau of Labor Statistics didn't begin to track older age brackets until 1994, so this may stretch back much further). The other is the very sizable drop in teen employment. One step down took place in the period after the collapse of the dot.com bubble; the other, larger decline was during the first two-some years of the Great Recession. In other words, (er, that rings odd!) I'm drawn to Figure 1 on the right. To make the contrast clear, Figure 2 depicts labor force participation by prime-age workers, using the same scale. [Note these two graphs track changes relative to 2007: an index, not an absolute change.]

Figure 2

What is going on here? Are older Americans no longer retiring? Indeed, given that this period would include the large Baby Boom cohorts, are they not only not retiring but also squeezing teens out of the labor force? There's a lot of research on older Americans. We are not only living longer but are healthier into old age. Fewer are engaged in manual labor, and so work is less tied to health. And then there are those who have been left hanging without pensions, or who duly saved but realize they might live much longer than any of their relatives ever had, and did not factor in the rise in healthcare costs. Too, many people actually enjoy their jobs, being out of the house, socializing with co-workers, customers, vendors. To them the end of mandatory retirement at age 65 was a boon. So it's not all one cause, and it's not all because older Americans have to work to keep bread on the table and (more important) pills in the medicine cabinet.

So I poked around the data a bit more. Is this a gender story? Figure 3 presents the breakdown for teens. First, these data are not corrected for seasonality. As you can see, there's a sharp sawtooth of summer jobs versus school studies, though that is less pronounced today than in the 1950s and 1960s. And yes, fewer young men are working. At the same time, and in contrast to the 1950s and 1960s, the data no longer show a gender distinction. In the generally minimum wage jobs in which this group labors, all received equally bad treatment. And both work less come the 21st century, with a sharper drop-off in 2007-2010; there seems to be a recession effect. For young 20-somethings, in Figure 4, there is less seasonality. This again matches intuition: while college students may have summer jobs, most Americans do not go to a 4-year college and/or delay their education, and even those in college graduate by age 24. And while fewer young men are working, again that is offset in part by more women working. Similarly, both curves decline during the Great Recession.

The final Figure 5 presents the "M" curve for select years. In 1976 proportionally far fewer women worked than today, and there was a tendency for women to drop out of the labor force in their child-rearing years (as my mother did) and then re-enter the labor force (again, as my mother did). Come 2006 and participation was far higher, while the "M" is almost gone. So in general this is not a story of women staying home so the men could work. If anything it's the opposite: more men stay home, and the women work.

Figure 3 Figure 4 Figure 5

As indicated by the "M"-curve in Figure 5, age-specific graphs indicate a consistent narrowing of gender distinctions, but this is much more pronounced at younger than at older ages. Maybe the Baby Boomers were different – but to answer that, you'll need to come back in another 5 or 10 years, when the generation that follows them begins to hit the historic retirement age. To get a better sense of this, see Figures 6, 7 and 8.

Figure 6 Figure 7 Figure 8

So maybe the old are squeezing out the young. Are teens less reliable? Less socialized into hard work? Have done fewer jobs and are harder to train? Maybe. At the same time, I found data in the BLS "Tableau" on work versus schooling. I graph those data in Figure 9 and Figure 10 below. What is striking is that the "work plus school" share is fairly constant. Now this provides no hint on the decisions that lie behind this. Are the young pursuing schooling (which includes technical training) because they can't find a job? Or are they wanting more education/training, and thus have chosen not to work? I've no time to delve into the research of labor economists on the issue. The one thing that is clear is that on average the young aren't sitting around playing games on their cell phones all day. Or if they are they're doing it in class and on the job and (it seems) while driving. Oh, and I'm a mean old professor: I require students to stow phones, pads and laptops in their backpacks during class.

One OS, multiple safety applications

The latest version of our certified OS for ADAS systems and digital instrument clusters has a shorter product name — but a longer list of talents.

Paul Leroux
Can you ever deliver a safety-critical product to a customer and call it a day? For that matter, can you deliver any product to a customer and call it a day? These, of course, are rhetorical questions. Responsibility for a product rarely ends when you release it, especially when you add safety to the mix. In that case, it’s a long-term commitment that continues until the last instance of the product is retired from service. Which can take decades.

Mind you, people dedicated to building safety-critical products aren’t prone to sitting on their thumbs. From their perspective, product releases are simply milestones in a process of ongoing diligence and product improvement. For instance, at QNX Software Systems, we subject our OS safety products to continual impact analysis, even after they have been independently certified for use in functional safety systems. If that analysis calls for improved product, then improved product is what we deliver. With a refreshed certificate, of course.

Which brings me to the QNX OS for Safety. It’s a new — and newly certified — release of our field-proven OS safety technology, with a twist. Until now, we had one OS certified to the ISO 26262 standard (for automotive systems) and another certified to the IEC 61508 standard (for general embedded systems). The new release is certified to both of these safety standards and replaces the two existing products in one fell swoop.

So if you no longer see the QNX OS for Automotive Safety listed on the QNX website, not to worry. We’ve simply replaced it with an enhanced version that has a shorter product name and broader platform support — all with the same proven technology under the hood. (My colleague Patryk Fournier has put together an infographic that nicely summarizes the new release; see sidebar).

And if you’re at all surprised that a single OS can be certified to both 61508 and 26262, don’t be. As the infographic suggests, IEC 61508 provides the basis for many market-specific standards, including IEC 62304, EN 5012x, and, of course, ISO 26262.

Learn more about the QNX OS for Safety on the QNX website. And for more information on ISO 26262 and how it affects the design of safety-critical automotive systems, check out these whitepapers:

Peugeot Fractal concept


Peugeot has unveiled the new Fractal concept ahead of the Frankfurt Motor Show. This is an electric urban coupé which explores the sense of hearing in addition to sight and touch. According to Peugeot, it makes driving "even more instinctive, creating an unparalleled on-board experience".

It was designed by StelLab, a PSA Peugeot Citroën research unit. The Fractal concept was developed in partnership with sound designer Amon Tobin. It features a high-definition holographic head-up display screen. A 45-degree polycarbonate strip delivers additional information and creates an impression of depth. This allows the driver to customise the way information is shown.



The concept also explores new design and manufacturing processes. 3D-printed parts represent more than 80% of the interior trim surface. The anechoic materials were made through generative design - a process used to achieve the perfect component.

A 30 kW/h lithium-ion battery powers two electric motors, each delivering 75kW/102hp, fitted to the front and rear axles to provide a total output of 125 kW/170hp and combined-cycle autonomy of up to 450km. Variable ground clearance allows the vehicle to adapt to different types of terrain. The 7cm clearance for motorway driving improves aerodynamics to range and boost battery life. This can be increased to 11cm in urban environments, allowing the car to take speed humps and car park entrances in its stride.

As for it's dimension, the car is extremely compact, at 3.81m long and 1.77m wide, allowing it to weave through heavy traffic. The 19‑inch Tall&Narrow wheels are positioned at either end of the car, with an overhang of just 0.52m front and back to improve manoeuvrability.

The car styling features dynamic lines that flow along the length of the smooth body. The Coupe Franche, a straight line dual paint finish, further enhances the sense of vitality with a sharp shift from intense pearly white to matt black at the door hinges. The upper body features a removable roof to turn the coupé into a cabriolet. An LED strip above the vent at the rear shows the battery charge status via an equalizer-type display. These LEDs also act as rear lights when PEUGEOT FRACTAL is moving. The light signature in the front starts below the grille and flows over the headlamps. It also includes scrolling indicators.
