THROTTLE TRACTION CONTROL FOR AUTOMOTIVE VEHICLE

摘要

An engine traction control system generates a control cycle of a varying dut y cycle which controls the pressure level in a pneumatic actuator in the engine power control (46) linkage to thereby reduc e engine power when the driven wheels (24, 28) begin slipping during the vehicle acceleration. The duty cycle is set as a functio n of wheel speed error between the average wheel speeds of the driven and nondriven wheels (16, 20), and also as a function of the change in the error between calculation cycles.
