Method for operating an actuator, in particular a Hydrostataktors for actuating an automated friction clutch

摘要

The invention relates to a method for operating an actuator for actuating an automated friction clutch of a drive train of a motor vehicle with an electric motor and a kinematics device driven by it, by means of which along an actuation path of the friction clutch imparts a contact force on the friction clutch and dependent on the friction clutch to be transmitted clutch torque set by the contact pressure and the contact force is detected by a sensor in the actuator. In order to reduce errors in the setting of the clutch torque, offset compensation of an offset of the sensor to a base value is performed in an operating situation of the actuator with an assumed freedom from force.
