ABSTRACT:
A method for preventing excessive spin to the driven wheels of a vehicle by determining the value of slip where the wheel/road tractive force is maximized for the particular coefficient friction road operating surface. The reaction torque, as translated through the differential, is considered and wheel control is therefore optimized based upon individual wheel acceleration characteristics and cross-differential torque transfer.
