Sean, I am glad that you still ike your prius.

But what you commented here is still disturbing. 

I can tell you that, after driving the car for 3+ years, there has been about 15 or so instances when the car accelerates wihout my assistance - not too much but nonetheless an acceleration. 


Not every driver should be expected to learn how to manage the uninteded acceleration in my opinion.

Thanks for the headsup, Antony. I am going through the court transcript right now. I will get in touch with you.

That's a good question. I don't know. In this particular case, the expert witness was only allowed to see the source code under confidentiality agreement -- so that the exeprt's findings are made public in the court transcripts but not the source code itself.

We whole-heartedly agree with you Duane, as far as the credibitliy of Michael Barr is concerned.

Are there other cases in automobile or even aircraft law where source code has been exposed and analyzed and then made public?

I'm not any kind of an automotive expert, so I can't speculate on what X might be. I am glad that many of the details are public information. In so many product liability cases, the details remain confidential due to out of court settlements.

I've read material from Michael Barr for many years now. Based on that, I would consider him to be a very credible expert.

The point I was trying to make was that this particular legal document, a ruling by Judge Selna,  had some interesting technical clues in it as to the nature of Task X. Anyone interested can contact me for further details.

Accelerator problem in new Toyota
cookiejar   10/26/2013 3:00:03 PM

I recently took out a new Toyota Sienna van for a test drive at my local Toyota dealer. 

I was taken aback by my inability to maintain a steady speed.  It seemed the throttle control was noisy, in that the vehicle would either surge ahead or hold back.  When I turned on the cruise control the vehicle maintained a smooth steady speed.  The salesperson with me simply denied there was a problem. 

It appears that Toyota still has an accelerator sensor problem - perhaps whiskers caused by lead free solder or noisy pots. 

It's unbelievable that after all this time and publicity, Toyota seems unable to solve the problem.

Automation will be a process with artifacts

Automation will be having its own artifacts, some comments says here that the increase in acceleration is a manageable event, what I have noticed in most of the recent auto throttle control is some-kind of increase in the rpm and ultimately this will lead to increase in the acceleration in the car in transmission-ed. But the case has reached up to legal investigations beyond the engineers hand.

"Legal documents are usually dull as ditchwater"

 

Yeah, that is the TRUTH.  So is actual court.  That's why they have to create shows like Law and Order.  LOL

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
