The US hub of driving dynamics is, not too surprisingly, the
University of Michigan. Here's a link to some work by the
Automotive Research Simulator but that's only the tip of
the ice berg.

I strongly recommend that you go to this site and look through
most of the links. You will find excellent work both online and
by the researchers and their past publications.

I first discovered them in 1989 when I was solving for what was
to me a major obstacle: the behavior of a truck and semi-trailer
when you back up the truck part with the wheels turned. It may
seem simple (and it may be simple if you know more math than
me ;-) but I found it difficult to work out as a finite difference
solution.

I'm working on a "toy" driving simulator application for a VR
display, and just need to provide a car that is more or less
accurate.  Inputs I'm prepared to feed to the algorithm include
a steering offset, acceleration, brake, ground friction coefficient,
and ground slope (is there anything else that is absolutely
necessary?).

I'll take existing code, psuedocode, a collection of algorithms,
whatever is available.
