White on 23 Mar 2010 22:55 Consultants say interference in vehicle electronics is possible Neil Roland Automotive News -- March 23, 2010 - 4:42 pm ET WASHINGTON -- Testing by Toyota Motor Corp. and other automakers has never detected electronic causes of sudden acceleration because it has looked for the wrong evidence and because this evidence is difficult to detect, three British consultants with doctorates in engineering said today. The consultants, who expect to meet tomorrow with U.S. investigators, said Toyota's pedal assembly and electronic throttle-control system have a number of parts that aren't shielded against electromagnetic interference, or EMI. "Thirty years' empirical evidence overwhelmingly points to (sudden acceleration) being caused by electronic system faults undetectable by inspection or testing," said Keith Armstrong, a engineering consultant from the United Kingdom who appeared with two other engineers at a Washington news conference organized here by consumer advocates. Armstrong, who said he was interviewed last month by U.S. National Highway Traffic Safety Administration investigators, said the problem with electronic interference is industrywide. "EMI is endemic in electronics," he said. EMI is electrical disturbances in the circuits. Real-life EMI Tests by Toyota and other automakers don't cover most real-life EMI, nor do they simulate typical faults to verify that backup measures work, Armstrong said.

They still want Audi to recal 1985 Audi 5000's. Ed "C. E.

They still want Audi to recal 1985 Audi 5000's. I saw one the other day. I don't think the owner will sell it to them because it was in mint condition. They can recall all the rest, I'm sure most of them have been in junkyards for a while...

I couldn't find an official toyota talk forum but I found this one....it has all the info about the 2010 Toyota Motor Corp. Recall & Prius brake pedal fix. I found it to be very informative, it has more commentary than just the official toyota recall site.... http://www.ToyotaBrakeRecall.org check it out

They still want Audi to recal 1985 Audi 5000's. Ironically, Audi ran magazine ads in the 1980s that discussed adapting Audis to America. In one ad they said the corrosion protection had to be improved to handle the salt we poured on the roads in the winter, and in another ad they said RF interference was a lot worse here than in Europe. |
