Abstract:
A method for controlling an automated friction clutch arranged in a drive train of a motor vehicle in the force flow between a drive engine (3) and a drive transmission (4), which is configured to close passively by spring pressure and can be disengaged and engaged by way of a pressure-medium-actuated clutch actuator (14), such that the actuation position x_K of the clutch actuator (14) or of an associated transmission element is determined and used for controlling the friction clutch (2). To improve the accuracy and reliability of the clutch actuation it is provided that in addition, an actuating pressure p_K of the clutch actuator (14) is determined and that a required change of the clutch torque M_K to a new nominal value M_K_soll takes place under pressure control, in that the actuating pressure p_K of the clutch actuator (14) is set to a nominal value p_K_soll which corresponds to the nominal value M_K_soll of the clutch torque M_K.
