Instead of a flip and holier-than-thou response, why don't you try to explain what part I got wrong from the Toyota press release which stated:
The Prius braking system uses both conventional hydraulic friction brakes and a regenerative braking system which switches the electric drive motors into brakes to generate electricity.The system features a sophisticated self- protection function which cuts engine power if moderate brake pedal pressure is applied and the accelerator pedal is depressed more than approximately 50 percent, in effect providing a form of “brake override.”
This function, which is intended to protect the system from overload and possible damage, was found to be functioning normally during the preliminary field examination.
Now, what part of the Toyota Prius braking system do I not understand?
The part where you want me to explain to you how it works. Like I said, read up (do the work) & you’ll change your mind, I think. If you read Toyota’s response correctly. you’ll see it’s all there. How’s that for flip?
Actually, in the story in the OP:
“Toyota Motor Corp. said Monday it believes the driver of a Prius involved in a high-speed incident on a California highway repeatedly pressed the brake and accelerator, apparently defeating a system that can prevent unintended acceleration.”
Why is a guy, trying to stop his car, depressing the accelerator multiple times - the same accelerator he said he reached down and tried to pull up because it was “stuck to the floor” even though he would have needed the arms of a chimpanzee to even touch the front of the pedal?
