Abstract
Techniques for controlling the spin of driven wheels of a vehicle also including non-driven wheels and an engine controlled by a spark angle and/or throttle position. The spark angle is controlled by a signal responsive to a slip error signal and a slip error derivative signal in order to alter the spark angle in a manner that controls the spin of the driven wheels. The throttle position is controlled by a throttle position control signal that is responsive to a slip error signal, a slip error derivative signal, and a slip error integration signal, in order to adjust the throttle position in a manner that controls the spin of the driven wheels. Wheel spin also can be controlled by the combination of a spark angle control signal and a throttle position control signal.
