ABSTRACT:
A system and method of limiting the wheel slip of a driven wheel of a vehicle to a maximum allowable value so as to maximize the driven wheel tractive force is described. The driven wheel tractive force represented by an expression including the engine intake air flow area, a load variable function and the speed of an undriven wheel is continually monitored. The value of the monitored tractive force at the time the driven wheel slip reaches a maximum allowable value is identified and stored. When the slip exceeds the maximum allowable value, an intake air flow area is limited to a value determined to return the driven wheel tractive force to the identified tractive force at the maximum allowable wheel slip value.
