Toyota: They Claim It’s Not Drive By Wire’s Fault

The Toyota gas pedal recall has caused quite an uproar. Toyota says that it is not the drive by wire system that is at fault for the runaway cars as quoted by the LA Times:

November 29, 2009: A new Los Angeles Times story claims a number of Toyota drivers say their vehicles had still accelerated out of control with the floor mats removed. The Times also reports complaints of unintended acceleration increased after Toyota began using its drive-by-wire system in 2002, starting with the Lexus ES 300. According to the Times, unintended acceleration complaints on Lexus ES 300′s jumped from an average of 26 per year in 2001 to 132 per year in 2002, and there had been 19 deaths since 2002 related to unintended acceleration in Toyotas, compared with 11 deaths connected to all other automakers combined. The story also notes Toyota has been investigated for unintended acceleration more times than any other automaker, and that 74 of 132 complaints lodged against the 2007 Lexus ES 350 were for cases of unintended acceleration. Toyota has no explanation, but says its drive-by-wire system is not to blame, again citing the November 2 NHTSA report.

But I have seen no mention of the other items that no longer have mechanical links.

The Brakes: Remember that you can put your foot on the brake while flooring your gas pedal and the car would not move and I mean some pretty powerful cars you can do that with. Even though the engine is running away I can slow down my mechanically connected brake pedal car enough to save my life.

Transmission: Dammit why can’t I put the dam thing in neutral??????????????? Haven’t seen that stupid question asked by anyone yet.

Drive by wire is not just the engine controls it also involves the transmission and the brakes. Are the component shielded against waves that may emit the same signal as the computers that control car functions? Like your neighbor who can change the channel of your television those devices may have the same vulnerability.

Just putting it out there no matter how stupid it may sound! And it’s not just Toyota that uses drive by wire and some of them use Microsoft as the operating system. Hmmmmm???????

December 5, 2009: Following an op-ed piece in the Los Angeles Times, Toyota writes a letter to the paper reiterating its stance that the floor mats were the root cause of most unintended acceleration claims. The company defends NHTSA and its methodology.

Here is how to try to save your ass if you have a runaway.

    Can’t load the video.
    Brakes won’t work.
    I would turn off the key one click.

    The brakes will not work during hard acceleration. On this vehicle the brakes are assisted by engine vacuum which is too low while the engine is accelerating to provide enough assistance to stop.

    I am looking forward to Toyota finding the real cause of this problem. I do not believe they have yet. 2-25-10

    Yesterday our 2008 Toyota Highlander, which is not supposed to be included in the sticking pedal recall, accelerated on it’s own, nearly causing my wife to rear end a coal truck. She was accerating to get on the highway, she let off of the accelerator pedal and the car kept accerating. She applied the brakes, the car would not slow down. She shifted the car into neutral and the engine RPM’s kept climbing, but the car slowed to a stop. She shut the engine off, looked to see if the floor mat was interfering with the accelerator pedal, found that the mat was clear. She re-started the car, and everthing was normal. The car is at the dealership service department. I find it hard to believe that the accerator pedal mechanically stuck. The engine was still revving up until the ignition key was turned off. When the car was re-started it was operating normally. Toyota needs to quit insisting there is no problem with the electronics, drop the pride issue, find and fix the problem. Toyota makes a good vehicle, but they have a big safety problem, and they need to get it fixed before more inocent people are injuured or killed in a run away Toyota.

    I think this drive-by-wire problem is similar to the problems the Airbus A320 and related airplanes have with their fly-by-wire controls. I’m thinking of the one that sank off the coast of Brazil after flying through a thunderstorm. Lots of electrical interference in a situation like that. The Meteoquake site I listed discusses this, and a thread on wattsupwiththat.com around the time of the crash off the coast of Brazil.
