Hi, I've got the following question:

Has anyone got an idea for cars torque?

I mean I'd like to do it through a real torque curve.
But my question is how to do it... (not asking for code but for sketches...).

I was thinking and came up with this:

Give the torque curve a formula, I think if I take a look at the graph I think most cars just have a quadratic formula (or maybe a third dimensional).
So, to create a formula won't be that hard (I don't see problems in this one yet).
But how to go further?

I came up with this:

Every gear has each own curve, which mean its own formula, still no problem.
But how can I implement the formula?
Maybe by using RPM?
How the car accelerates is defined by the acceleration of rpm (correct me if I'm wrong).

By using the the formula I can say x = rpm.
y = acceleration speed.

And then there is the speed down (by releasing the driving button) this acceleration will be defined by a "- constantnumber * weightofthecar and some other car-related code".
The acceleration (or should I say de-acceleration) of the rpm will be something like:
Torquecurve * "- constantnumber * weightofthecar and some other car-related code.
So that when someone releases the driving button and pushing it again, the rpm will decrease and then increase.
And because rpm = x I can find the y = acceleration whenever I want...

My question is, will this be a good way to do this?
Is it reliable?

Or does anyone have any other ideas?
Ideas are always welcome,

Thanks in advance.

Angelo.
