Abstract

The present invention relates to a clutch actuation device wherein the functional connection between actuation of the clutch and the excursion of the clutch pedal is made via an interposed electronic control unit. A first depression sensor is located on the clutch pedal for the purpose of determining the set value and a further sensor for determining the actual value is located on a lever of the clutch. The lever is connected to an actuation cylinder which is adjustable by means of a control valve in response to the output signals from the electronic control unit. In addition to the set value which is determined via the sensor, the electronic control unit is supplied with an additional signal from a regulating unit; the additional signal being dependent on the presence of a regulating function of a locking protection control system (LPCS). Accordingly, the above-described device is designed to allow automatic actuation of the clutch in an LP control system.
