Abstract
The vehicle described herein employs a mu logic module. The mu logic module monitors vehicle operating conditions, and based on those operating conditions determines a road surface mu in response to a wheel slip event. The road surface mu is then used to determine a drive force to minimize or control the wheel slip event. The mu logic module continually monitors and adjusts the drive force provided to at least one of the wheels to maximize the applied drive force, while stabilizing and controlling wheel slip events to ensure safe operation of a vehicle.
