A system for controlling an electro-magnetic clutch of an internal combustion engine mounted on a car, which has a drive member secured to a crankshaft of the internal combustion engine, a magnetizing coil provided in the drive member, a driven member adjacent the drive member, and a transmission secured to the driven member. An engine speed detecting circuit is provided for producing an output when the engine speed exceeds a predetermined speed in an accelerating condition, the output signal being retained until the engine speed falls below a speed different from the predetermined speed. A gate is responsive to the output of the engine speed detecting circuit for producing an output which is applied to a switching transistor. The transistor is turned on by the output, so that a rated current passes through the magnetizing coil for engaging the clutch. |
