A matter of urgency: preparing for ISO 26262 certification

Two weeks ago in Tokyo, QNX Software Systems sponsored an ISO 26262 seminar hosted by IT Media MONOist, a Japanese information portal for engineers. This was the fourth MONOist seminar to focus on the ISO 26262 functional safety standard, and the theme of the event conveyed an unmistakable sense of urgency: “You can’t to afford to wait any longer: how you should prepare for ISO 26262 certification”.

In his opening remarks, Mr. Pak, a representative of MONOist, noted that the number of attendees for this event increases every year. And, as the theme suggests, many engineers in the automotive community feel a strong need to get ready for ISO26262. In fact, registration filled up just three days after the event was announced.

The event opened with a keynote speech by Mr. Koyata of the Japan Automobile Research Institute (JARI), who spoke on functional safety as a core competency for engineers. A former engineer at Panasonic, Mr. Koyata now works as an ISO 26262 consultant at JARI. In his speech, he argued that every automotive developer should embrace knowledge of ISO 26262 and that automakers and Tier 1 suppliers should adopt a functional "safety culture." Interestingly, his argument aligns with what Chris Hobbs and Yi Zheng of QNX advocate in their paper, “10 truths about building safe embedded software systems.” My Koyata also discussed the difference between safety and ‘Hinshitu (Quality)” which is a strong point of Japan industry.

Next up were presentations by the co-sponsor DNV Business Assurance Japan. The talks focused on safety concepts and architecture as well as on metrics for hardware safety design for ISO 26262.

I had the opportunity to present on software architecture and functional safety, describing how the QNX microkernel architecture can provide an ideal system foundation for automotive systems with functional safety requirements. I spoke to a number of attendees after the seminar, and they all recognized the need to build an ISO 26262 process, but didn’t know how to start. The need, and opportunity, for education is great.

The event ended with a speech by Mr. Shiraishi of Keio University. He has worked on space satellite systems and offered some interesting comparisons between the functional safety of space satellites and automotive systems.

Safety and reliability go hand in hand. “Made in Japan” is a brand widely known for its reliability. Although Japan is somewhat behind when it comes to awareness for ISO 26262 certification, I see a great potential for it to be the leader in automotive safety. Japanese engineers take pride in the reliability of products they build, and this mindset can be extended to the new generation of functional safety systems in automotive.

Test Drive




Smart

After a few delays and phone calls  to schedule a meeting, i finally got to test drive the electric Fortwo in downtown Lisbon.

A friendly salesperson asked me if i had any experience with electric cars (Negative answer), making made a brief introduction to the car and technology, saying that it was the fuel source of the future.

After sitting in the car and explaining me the main features in the car, i finally got to drive it around town, where it felt just perfect, small enough to travel around through narrow, ancient streets of old neighborhoods, and powerful enough to climb steep hills and sprint through heavy traffic. Oh, and because it doesn't have that nasty gearbox of ICE Smarts, it is a much more relaxed drive than their gas siblings.

Back to the dealership, i considered that the car didn't justified the huge price difference regarding their ICE siblings, to which the sales person replied that he couldn't make a significant discount on it because few were sold and there wasn't enough scale to lower the price, leaving the possibility for me to buy a gasoline Fortwo or renting the Fortwo ED as alternatives.

Smart believes that electric cars are still for a few single-minded people that buy more with their heart than with their wallet.




BMW

I've saved the best for last, when i got into the dedicated BMW "i" dealership in downtown Lisbon (In a strategic spot, with other dealerships nearby, like Audi, Peugeot, Toyota or Chevrolet), the first thing that it struck me was how different it looked from other dealerships(1), Premium or non Premium, with minimalist decoration and a nice contrast between colors, it looked more like i've entered an Art Gallery than a car dealership. 

Two minutes after getting inside the dealership, i'm greeted by a salesperson in a "i" polo shirt (Like every other staff members), and after a few early questions, the i3 is showed to me by him, with the salesperson proving to be a devoted fan of electric cars and very much focused in highlighting the top selling points of the car.

After this first presentation, i'm introduced to another staff member that would be with me during the test drive. Before getting into the car, i'm asked to lend my ID car for them to register my data on their Db (Glad for them i'm not paranoid about this kind of stuff).

The test drive had predetermined route, that pretty much covered all kinds of roads and situations, with the added bonus of visiting one or two more scenic places in Lisbon.

As for the i3 itself, all i can say is this: "Weeeee!", besides being a small car with not that much weight to carry around, it shows on how lively it is, it has more than enough power to blast every other car in traffic lights, let's just say that if i had one, i would jeopardize my drivers licence every time i had to drive it...

After stopping in Monsanto Green Park, the staff member (An electronics engineer), explained me how to plug and unplug the car to a fast charger, encouraging me to unplug it. During the test drive i made a few questions on the technology behind the i3 (Materials, charging rates, batteries, software, etc), to which he replied willingly and accurately.

Back to the dealership, i'm introduced to a third member of the staff, "which would assist me through the configuration of the car" (It takes a specialist to do this?!?!?).

During the extensive configuration of the car, at times it felt more like we were doing Interior Decorating of a house than a car, so many were the options. (Yes, it does).

After more than 5.000 euro of optional equipment later, we finished the configuration and by then the salesperson joined us and asked my opinion, i objected that the price was too high, to which he replied that there was a lot of new technology involved in this car, so the price had to be high. I asked if they had any demonstration car, but they responded that BMW Portugal had yet to put any demonstration i3 for sale, giving the possibility for me to rent the car at an interesting fare.

The best plug-in car i've tried and probably the best staff in selling electric cars. But be careful with the options list as you might end up with stratospheric numbers in an already overpriced car.
