Abstract

There is disclosed a system for controlling creeping movements of a motor vehicle having a power train with an automated clutch between the engine and the transmission, an electronic control unit for the clutch, and sensors which transmit to the control unit signals denoting the condition of one or more brakes, the positions of an operator-actuatable load lever for the engine, and others. Signals from the control unit are utilized to operate the clutch and, to this end, the control unit includes an arrangement for effecting a creeping movement of the vehicle when the transmission is in gear, the brake or brakes is or are idle, and the load lever is actuated. Such arrangement can effect the transmission of torque in accordance with at least one first predeterminable function to thus induce a creeping movement of the vehicle. The control unit further includes a device for effecting a starting movement of the vehicle in response to actuation of the load lever while the brake is or are idle and the transmission is in gear; such device includes an assembly for selecting the transmission of torque by the clutch in accordance with at least one second predeterminable factor.
