Abstract

A motor vehicle clutch control system for a motor vehicle having an electrical system including an ignition switch (70). The control system includes a hydraulic power circuit (30) including an electrically driven pump (33), an accumulator (35) and a clutch actuator (39), at least one sensor (71) for sensing a predetermined vehicle condition and a control unit (49) which controls the actuator in response to sensed conditions of the associated vehicle to operate an associated clutch (18). The control unit (49) causes the pump (33) to charge the accumulator (35) for subsequent operation of the actuator (39) when the imminent starting of the associated vehicle is sensed by the sensor (71) but prior to operation of the ignition switch (70). <IMAGE>
