Brakes are mechanical systems. Can anyone figure out how the computer could even begin to disable them? I guess one could imagine the ABS module could be used to cut out the brakes permanently instead of pulsing them. (Maybe this is another reason people should learn to brake properly instead of relying on dumbing-down systems... ;-)
- hugh3 17y agoI'm not sure. But I think that one thing worse than disabling them might be to wait until the car reaches freeway speed and suddenly apply full brakes to, say, the front left wheel.
- roc 17y agoJust about anything with ABS or traction control has a digital override of the drivers intent. That was the big fact people seemed to overlook during the Toyota-acceleration fiasco. I wasn't nearly as concerned about the actual problem as I was about the computer deciding a brake instruction from the user should be ignored. Modified, certainly. But ignored? It boggles the mind.
- jrwoodruff 17y agoI don't remember hearing this, mainstream media was so focused on floor mats and sticky accelerators and what not. Are you saying that while the car was accelerating the computer overrode the driver braking and failed to apply any brakes? Source?
- ax0n 17y agoI'd need to dig in order to find it, but it is, indeed, possible to make the brakes act MUCH different than the driver intended, once you have patched the ECU firmware. I'm not 100% certain you can completely shut off the brakes (as in, driver puts two feet on the pedal and it sinks to the floor without engaging any brake pads at all) however it may be possible to disable ABS or possibly to bias all braking to only the left wheels, for example.
