Has it been ruled out that it wasn't just a case of the wrong pedal being pressed? That is often the simplest explanation for cases like this. The driver swears they were hitting the brake pedal, but that car just kept accelerating! Not surprisingly, these cases often (but not exclusively) involve elderly drivers, new drivers, or car rentals.
- praptak 13y agoWe'll never know, unless the pedal was being pressed hard enough to bend it out of shape. Maybe it is an additional reason to make the system fail safe - assume people will press the wrong pedal and then sue.
- MichaelGG 13y agoSeems like for software-driven cars, a small 15-minute diagnostics log would be a good idea. A black-box without audio recording, to avoid privacy implications.
- sliverstorm 13y agoThe weird thing is we should be able to know! I recall at one point one of the incidents was investigated, and they said that under hard braking at high speeds, particularly sustained hard braking, certain chemical changes happen in the surface of the brake pad due to the temps. They said they found no evidence of those chemical signs.
- WalterBright 13y ago> certain chemical changes happen in the surface of the brake pad due to the temps In laymen's terms, we call that "burning" :-)
- sliverstorm 13y agoBrake pads don't usually burn in cars.
- chc 13y agoThis would only be expected in cars where the brake pad is necessarily engaged when you press the brake pedal.
- sliverstorm 13y agoI thought cars were still generally like that. The ABS can step in and take over, but without pro-active behavior from the ABS you have a direct hydraulic connection. I didn't think ABS was being called upon as involved here.
- chc 13y agoBrakes are computer-controlled in many cars these days, such as the Prius. The computer chooses between engaging magnetic brakes or the hydraulic system or routing force directly from the pedal to the brakes.
- Symmetry 13y agoSince most of the victims of uncontrolled acceleration in Toyota cars were elderly, I think we can conclude that this was the case in the majority of incidents. Competes don't discriminate by agree on their own.
