A system for controlling an electromagnetic clutch of an internal combustion engine mounted on a vehicle, which has a magnetizing coil and a transmission. A vehicle speed detecting circuit is provided for producing an output when the vehicle speed exceeds a predetermined speed and another detecting circuit for a vehicle travelling condition is provided for producing an output by signals from a top-gear switch provided in the transmission and from an engine speed switch. A trouble detecting circuit is provided for producing a trouble signal when the output of the speed detecting circuit is not applied in spite of the output of the vehicle travelling condition detecting circuit. A gate device is responsive to the trouble signal for producing an output which is applied to a switching transistor. The transistor is turned on by the output, so that clutch current passes through the magnetizing coil for engaging the circuit. |
