ABSTRACT:
A system for controlling the clutch torque of an electromagnetic clutch for a vehicle having an accelerator pedal switch for producing an output signal when an accelerator pedal of the vehicle is depressed. A clutch current circuit including a transistor is provided for controlling the clutch current passing through a coil of the electromagnetic clutch. A logic gate circuit is provided responsive to the output signal of the accelerator pedal switch for controlling the transistor so as to decrease the clutch current to a low value and thereafter to gradually increase the current to a rated value.
