Abstract: A method for correcting an actuator characteristic of a clutch actuator for a friction clutch of a vehicle transmission after the commissioning thereof. The actuator characteristic relates a first desired variable, such as a desired clutch pressure, to a second desired variable, such as an desired actuator current. The method comprises the steps: approaching a quasi-steady-state operating point of the friction clutch; detecting a deviation between the first desired variable and an actual variable of the friction clutch; and setting up a correction function for the actuator characteristic according to the deviation.
