[RIG] Car trajectory automated by front wheels position.

SaWDo

Hi everyone,
I'm a fresh beginner into rigging and I'm looking for some help
I started to rig a car I modeled a while ago. I play a lot with driven key and controllers and I started to set some expressions to automatize wheels with the car translation.
I wanted to make the car follow the direction of the wheels when the car translate.
I searched all over the web for some help without any true answers.



So I tested to make an expression with a ratio between the rotation of the general controller with it translation.
It didn't work very fine

If a good fellow could help me in his freetime, I'll be more than happy



Thanks for your time and your help and sorry for my poor english

So I took some time yesterday to test some expressions and I made one who works on a little distance.

The problem is that a pivot point I made on a group stay in place so the rotation is weird 5 meters after.
I don't have any ideas left

I moved this thread from Technical Talk into Animation Showcase & Critiques, so hopefully you should get more rigging eyeballs in here.

Good day! Did you manage to resolve the issue? Now I am also looking for an answer to it and cannot find anything on the Internet.

I would be immensely grateful for any information on this issue.
