Hello,

Thanks to all the contributors.
I have a question on the models. Maybe you can help.

This is what I search:
- The mathematical statement of a car model.
- I understand that it is an ODE x'=f(x,t) which is solved via explicit
Euler with dt=0.005 .
- However, I don't find a paper, documentation, web page, comprehensible
code piece, etc that names f.

I actually just need these parameters: geometry, CoG, mass, inertia,
wishbone joints, spring-damper coeffs; and the mathematical equations of
tire force and torque.
I understand there are probably hundreds of cars. Having one typical
specimen would be nice.
I can work with DAE as well as with ODE.

This is where I searched unsuccessfully (not meaning to brag it should have
been somewhere but rather that I tried and am glad for any help):
- FAQ
- src/interfaces/raceman.h (pointed in the FAQ)
- various other header and source files on github
- linked papers and their references
- videos

Sorry if I missed it in an obvious spot.
Thanks for any help.

Cheers,
Martin
