Re: Drive By Wire
As far as DBW and safety is concerned Toyota didn't have the proper defaults in their programming to eliminate a possible open throttle failure.....most OEM's run DUAL TPS sensors on the throttle blades, one to follow the throttle position as to the pedal position and the other to verify that this indeed happened and if not to throw the engine into a "limp" mode to allow control until it can be repaired.....it would not be difficult, as some have mentioned, to program this system to do anything you would like to try and the best part is it would be undetectable and if properly done impossible to find.....sort of like a "ghost in the machine"....
As a journeyman industrial machine builder, I have seen and used some really interesting and versatile micro sensors, software, and inovative programming techniques to accomplish many issues relating to automated industrial machines.....and now that sensors, computers and software are being used to control an automotive "machine".....good luck....the only limiting factor is ones imagination.....
