Abstract
An engine traction control system generates a control cycle of a varying duty cycle which controls the pressure level in a pneumatic actuator in the engine power control linkage to thereby reduce engine power when the driven wheels begin slipping during the vehicle acceleration. The duty cycle is set as a function of wheel speed error between the average wheel speeds of the driven and non-driven wheels, and also as a function of the change in the error between calculation cycles.
