METHOD FOR ACTUATING A FRICTION CLUTCH

摘要

A method for actuating a friction clutch, in particular for a motor vehicle drivetrain. The friction clutch is acted on with a clutch pressure generated by a hydraulic actuator arrangement which has an electrically actuable fluid source and which has a hydraulic actuator whose state is characterized by an actuator actual value. The actuator actual value is related to the clutch pressure. The method has the steps: forming a regulation-oriented model of the actuator arrangement, which model has at least one fluid source actuating variable as an input and at least the actuator actual value as a flat output and which model can be inverted; forming an inverse model of the actuator arrangement; and inputting an actuator nominal value into the inverse model and using the model actuating variable which emerges therefrom for actuating the fluid source.
