[quote=flu]Btw: the brake problem probably isn’t just limited to lexuses.
Me thinks most cars these days have power-assisted brakes…Not a brake engineer, but don’t they get they vacuum power from the engine? If an engine is at WOT, vacuum would drop after a few pumps, no?
Funny thing is I thought after the audi issues, that it was required when brakes are applied the ignition would be cut… I guess not.[/quote]
Audi’s problem was that the gas and brake pedals were too close together, and their brake pedal too small. The “unintended acceleration” was people hitting the accelerator thinking that it was the brake pedal.
Not sure how you’d actually be able to implement an “ignition cut-off” while braking (or even a fuel cutoff) – you’d have to put a lot of logic in wrt low speed exceptions (unless you want to restart your car every time you come to a stop – and stop-and-go traffic on the freeway would be just ridiculous), and it would pretty much kill every sports car out there as well.
