Method and apparatus for controlling an electromagnetic clutch for use on a vehicle

摘要

Method and apparatus for controlling an electromagnetic clutch which is incorporated in a power transmission system of a vehicle to transmit a torque of an engine to drive wheels, when the vehicle is started on a road surface having a low coefficient of friction. The method or apparatus comprises: a step or device for increasing progressively a transmission torque which is transmitted by the electromagnetic clutch; a step or device for detecting a slip of the drive wheels on the road surface; and a step or device for reducing, upon detection of the slip of the drive wheels, the transmission torque of the electromagnetic clutch until the drive wheels have ceased to slip on the road surface.
