Abstract
A method for controlling an automated friction clutch arranged in a drive train between an internal combustion engine and a gearbox, including: operating the friction clutch by a clutch actuator controlled by means of a controller; transmitting actual clutch torque by means of the friction clutch; implementing actual clutch torque that can be transmitted by means of the friction clutch and that can be adapted to the transmission behavior of the friction clutch by means of a control variable of the clutch actuator associated with a target torque of the clutch torque to be transmitted; operating the friction clutch in an engaged state while the target torque is specified; and adapting the target torque depending on clutch torque estimated from the operating data of the engine. The target torque corresponds to an engine torque that is generated by the internal combustion engine and that is applied with a safety margin.
