Beschreibung
Zusammenfassung:	A method and device for controlling a friction clutch arranged between an internal combustion engine and a transmission by means of a clutch actuator that axially actuates an actuating element of the friction clutch along an actuation path associated, by means of a clutch characteristic, with a target torque that can be transmitted by means of the friction clutch. To improve the quality of controlling of the friction clutch and to avoid the application of undesirable torque, it is proposed to compensate a hysteresis that arises between the target torque and the friction torque actually transmitted by the friction clutch along the actuation path by correcting a setpoint for controlling the clutch actuator with a corrective quantity.
