ABSTRACT:
A control system for an electromagnetic clutch of a motor vehicle. Idling speed of an engine of the vehicle is increased for providing a fast idle state when a choke valve of the engine is closed. In the fast idle state, initial clutch current is reduced for engaging the clutch at depression of an accelerator pedal, and thereafter the clutch current increasing rate is quickly increased when the engine speed and throttle opening degree become large. When the accelerator pedal is quickly depressed, the reduced rate is increased in accordance with opening degree of a throttle valve for providing quick start of the vehicle.
