<p>A system for controlling an electro-magnetic clutch of an internal combustion engine mounted on a car which is capable of eliminating residual magnetism during the deceleration of the car. The electro-magnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a driven member adjacent the drive member and a magnetizing coil provided in one of the members. An accelerator switch is provided for detecting the deceleration of the car and a car speed switch is provided for producing a signal when the car speed decreases below a predetermined speed. Both of output signals of the accelerator switch and the car speed switch are fed to a control circuit. The control circuit is such that the current flowing through the magnetizing coil is inverted upon occurrence of these output signals of the accelerator switch and the car speed switch, so that the residual magnetism in the clutch is eliminated.</p> |
