Arrangement for operating a friction clutch

Abstract

An arrangement for operating an automated friction clutch in a mechanical drive train of a motor vehicle driven by an internal combustion engine. A clutch operator actuator, by means of which a clutch operator of the clutch can be adjusted between at least one engaged position, in which the clutch is engaged at least partly for transmitting a torque, and a de-clutched position in which the clutch is completely de-clutched. An electronic control device controlling the clutch operator actuator. The electronic control device responds to a clutching requirement signaling device, which can be operated by an operator, and is designed for the purpose of supplying an engaging control signal which changes the position of the clutch operator from the de-clutched position to the engaged position to the clutch operator actuator in response to a clutching requirement signaled with the engine switched off and the clutch de-clutched. This makes it possible for the vehicle to be tow-started and towed away without the risk of damage to the drive train components.
