Electronic Throttle
It is amazing how many people have posted in response to the Electronic
Throttle (drive by wire)problem, or sudden acceleration, or unintended acceleration. I noticed that all the posters mention either their educational background or the amount of research they have done. I am surprised that Albert Einstein hasn't come out of his grave to respond. I have not read one post that mentioned a personal experience with the problem. I have had a personal experience with unintended acceleration. My wife and I purchased a 2006 Mustang GT coupe in October of 2006. Two months later the Mustang went full throttle all by itself. We visited a friend the Saturday before Christmas to see his light display. I pulled into his driveway and parked there for about 20 minutes (with the engine running) to look at all the lights. He did have hoops stretched across the driveway with all kinds of flashing lights. Upon leaving, put the car into reverse and backed out, then into drive to go forward. When I put it into drive the throttle went wide open all by itself (and yes my foot was on the brake, not thee accelerator). He lives on a corner, so I had to make a left 100' from his driveway, and a right turn at a corner 300' away. I was too busy trying to stop the car, and steer the car to make any other moves. It was the wildest 6-8 second ride in my life. I did in the process put my other foot on the brake also, to no avail. Total damage was $20,000.00 across 2 lawns, hit a Cadillac and ran into a garage (moved the garage 6 inches off its foundation). I don't know why these malfunctions (crashes) of the drive by wire system are a surprise. The engine controls are computer controlled, I repeat, computer controlled. How many times in the past has your computer crashed, or locked up, or malfunctioned. We did get rid of the Mustang, and I will not buy another vehicle without checking under the hood. If the vehicle does not have a cable or linkage controlling the throttle body I won't buy it.... |

Umm - they already have those miracle devices. They're called "gear shift levers with neutral positions". Why would you add another confusion factor and more clutter into the mix? -- Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') |

Let me see if I understand what you just said: Your Mustang hit a Cadillac and then hit a garage so hard that it knocked it 6 inches off its foundation. Then you had the choice of keeping and driving that same Mustang that had done that or get rid of it? Please forgive me if I think you are FOS to try to have us believe that the car that hit one car and then knocked a garage off its foundation was not totaled in the process. Your story lacks credibility. -- Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') |

They couldn't sell it in North America or half the rest of the world where- up 'till now, an "physical connection" needs to be between the driver and both brakes and steering. - I guess the cable operated parking brake makes the grade for the connection for brakes. (I guess hydraulic is still 'physical too) - but for steering it still requires a mechanical connection - hydraulic remote steering doesn't make the grade for on-road vehicles - although my brother says the "rubber railroad" articulated trucks - cement mixers etc - are fully hydraulic steering - - - -. |

It makes for an unusual immobiliser, and enables the engine to be cranked after an oil change until the oil pressure light goes out without starting, as long as the engine was stopped by lack of fuel supply. Best regards David BTW, I did describe the occurrences of unintended acceleration in three vehicles in this thread. --- news://freenews.netfront.net/ - complaints: --- |

Then you can shut your FOS mouth.... It sounds pretty silly to me. I used to have an MGB with a throttle that would stick all the time... I'd have to shut off the ignition, put out the clutch and coast to the side and free the damn thing up. Eventually after a few times of this happening on the highway I just got a new throttle cable. Stuff sticks. Stuff goes wrong. Life's just like that. That's why cars have operators who can deal with it when things happen. That's not an excuse to allow your car to get out of control. You've got a clutch and a key. Now, folks in a car where there is no clutch and no key and only a button have sort of a different problem, mostly because they don't have the reflexes to shut them off after many years of driving cars with a more conventional interface. That's partly the fault of the manufacturer for changing an interface that has been around for a a long time and partly the fault of the operator for not learning the new interface. --scott -- "C'est un Nagra.

It would create problems due to the steering being very hard to turn with the engine off (and some loss of braking capability). If that were the only option, then - yeah - that might be the preferred method. But, again, there is a better way: Best to simply throw the shifter in neutral. It's *already* there (no need to add more clutter, complecity, and expense), the engine is rev. limited in neutral so it won't self destruct. Then get the car safely stopped, *then* shut the engine off. The public could be educated to automatically think about it for when the unthinkable happens, and/or educational decals could be mandated for every car for benefit of the unteachable and to satisfy the lawyers and the nanny state. We don't need more switches and wires. -- Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x') |
