System for controlling the clutch torque of an electromagnetic clutch for vehicles

摘要

A system for controlling clutch torque for a vehicle which has a transmission and an electromagnetic clutch provided between an engine and the transmission, the clutch current being increasing with increase of engine speed. The system comprises an engine speed sensor for sensing the speed of the engine and for producing an engine speed signal in proportion to the engine speed, and an acceleration detecting switch for producing an acceleration signal. A vehicle speed detecting unit is provided for sensing the vehicle speed and for producing an output when the vehicle speed reaches a predetermined value at a low engine speed. A clutch current control unit is provided to respond to the output of the vehicle speed detecting unit and to the acceleration signal for increasing the clutch current along at an inclination up to a rated current.
