New sim code

I've ported the driveline code into vdrift master(suspension and tire code unchanged). Not committed yet.

Here is a simulation check pic:

In detail explanation:

The loads are the power in kW applied by the component. We have 576kW engine output(full throttle) and -553kW load from clutch, thus 23kW are accelerating the crankshaft(inertia 0.1kgm2).

The differential applies a load of -543kW on the driveshaft, 553 - 543kW = 10kW are accelerating the driveshaft(inertia = 0.25kgm2).

We have 2 * 271kW applied to the rear wheels. The rear tires are generating 2 * 260kW grip. 11kW are accelerating the rear wheel(inertia about 5kgm2), which corresponds to the 10kW front wheel acceleration load.

2 * 260kW - 2 * 10kW front wheels = 500kW of the 576kW are accelerating the car. The interesting part about the code is that component efficiency(transmission, differential) can be added rather easily to have a more realistic model.


The problem is. The cars behave different, are harder to drive(with keyboard at least). You have to be cautious with the F1-02 in the first gear with TCS enabled. On the positive side the brakes behave much better(brake distance about 50-70%). I've been thinking about some simple stability control and changes to the traction control. One could also try to tune F1-02 parameters(tires, wheels) to get the old behavior.

All in all it means the new code will affect car handling. Any suggestions how to proceed, it is a game and not a (hardcore)simulation after all?
