Abstract

A method for controlling a friction clutch in a drive train of a motor vehicle, using a clutch actuator, on the basis of a clutch model. A nominal characteristic curve of the clutch moment, which is transmitted via the friction clutch, is adapted continuously to actual operating parameters. In order to counteract a loss of comfort of the motor vehicle, which is caused by the running-in behavior, for example, of the friction linings of the friction clutch, the friction clutch is operated by way of different sets of operating parameters during a running-in phase of the friction clutch, and after the run-in phase of the friction clutch.
