摘要:
A method of controlling an automated friction clutch arranged in a drivetrain of a motor vehicle in the force flow, between a motor and transmission, and the automated friction clutch is designed to be passively engaged by spring pressure and can be disengaged and engaged by a controllable clutch actuator. The automated friction clutch is provided with a path sensor for detecting the clutch actuator travel such that during the operation of the motor a current key point of a torque characteristic, provided for controlling the friction clutch, is determined and used for adapting the torque characteristic. With the friction clutch engaged and without the clutch actuator exerting any force, several values of the actuator travel are determined at intervals from which a current engagement point, close to the actual engagement point of the torque characteristic, is determined and with which the torque characteristic is adapted.
