Re: [Torcs-users] Straight track

Hi Anand

This accel mean "accelerator pedal", so you can think of it as from 
"closed position of the carburetor or inlet/injection system" (0, which 
is of course nor fully closed, otherwise the engine would go off) up to 
fully open (1). As you can see this has no simple connection to the 
acceleration which will happen to the car, because this depends then on 
much more factors:
- Where you are on the torque curve
- Feedback from the wheels/drivetrain (differential, efficiency, 
momentum, this as well depends on
- Grip level of wheels, Forces on the car (Drag, impact of wall/car, 
slope of track, ...), etc, so even downforce etc. is involved. Basically 
most of the physics model/current state has an impact on the 
acceleration which will effectively result.

So there is no trivial way to get the precise acceleration from the 
pedal value (car->accel), it depends on a lot of car state.

Hope this helps.

Best regards

Bernhard

I have another doubt regarding the acceleration in Torcs. the "accel" variable can take a value between 0 and 1, with 0.1 being 10% acceleration etc. But how does it translate into acceleration in normal units like meter/second^2. In other words, if i give the accel a value of 1, how much does the velocity change by? If i stop giving accel any value after the car reaches a particular speed, what is the rate of decrease of speed?
