Sebring---- SUDDEN ACCELERATION

since the
driver *never* directly controls the fuel in anything except a diesel.
Even with a carburetor, the driver controls the *air* and the fuel is
added in response-
Wtih a carburetor the driver does control fuel on acceleration.

 

Every model of every car has some incidence rate of "sudden acceleration".
After all, we're all human. After Audi installed a brake/shifter interlock,
that was the end of it for the 5000. Nobody ever really implicated the
5000's pedal arrangement. So it appears the only variable was the people who
owned Audi 5000's were more likely to blame somebody else for their mistake.

To believe that anything mechanical actually happened in that case is to
ignore all the evidence.

So, if sudden acceleration happens for real, and you're too ignorant of your
car to understand what went wrong, then there's nothing you can do. You
can't explain what happened to anybody. What I mean is, if your throttle
sticks, you need to say "my throttle stuck" instead of "I suffered sudden
acceleration due to the negligence of a large corporation" so everybody
won't dismiss you as an idiot. Your throttle is pretty simple. If it moves,
you'll have to figure out why.

If you can't do that, just turn the switch off like you're supposed to and
deal with the shame in private.

 

I doubt that, I think it's for slower acceleration. If they put "throttle
response" in the hands of the computer, it can respond whenever it wants to.
At least that's the feeling I get when I drive one. If the computer decides
to downshift, it can wait before it actually opens the throttle.

This has got to be much easier for engine management. Cheaper? No. That's
just stupid, to think a motor-driven throttle is cheaper than a cable.

 

Drive one.

 

Of course, but you're missing the point that if they were going to open the
throttle when you wanted to, they wouldn't need throttle by wire. That's
what it's for, to allow the engine to respond in a more orderly (slower)
way.

 

That may well be one reason, but it is hardly the only reason.

One motor-driven throttle that can be used on EVERY engine in EVERY car
made by the company is cheaper to produce than a different throttle
cable for every engine/chassis combination. Not case-by-case, but in
terms of mass production.

As far as slowing down acceleration- that's mostly (my guess) to control
emissions and boost fuel economy. The real software benefit of TBW is
that the computer can cut the throttle whenever the automatic
transmission shifts, which allows the transmissions to be built even
lighter and cheaper than they already are because now the computer can
guarantee that there's no such thing as a "wide open throttle upshift,"
which transmissions used to have to be able to handle.
