Question by RLin · Apr 18, 2015 at 08:43 PM · rigidbodycarwheelcolliderracingmotortorque

Unity 5 wheel collider throttle "stuck".

Whenever I release the forward key for my car, the car continues accelerating for several seconds before it finally begins to decelerate. I am using mathf.clamp(input.getaxis("Vertical"),-1,1) so is this causing the issue? Also, the car is accelerating slowly, and changing both the torque and the drag of the rigid body, it cannot accelerate from 0 to 60mph in less than 8 seconds. The speed value is rigidbody.velocity.magnitude * 2.237. The 2.237 is to convert it from meters per second to miles per hour. The rigid body's mass is 1500. How can I fix this?

Finally fixed the problem, the forward friction wasn't great enough so the wheels were in a permanent skid, even if they were not accelerating. Increasing the wheelcollider forward friction fixed both of my problems.

Good to hear you found your answer! I'd just like to know, what value for forward friction was adequate enough? I think I have a similar problem.
