Abstract:
A method for correcting an actuator characteristic of a clutch actuator for a friction clutch of a vehicle transmission after the commissioning of the vehicle. 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 includes approaching a quasi-steady-state operating point of the friction clutch. In addition, a deviation is detected between the first desired variable and an actual variable of the friction clutch. Also, a correction function is set up for the actuator characteristic according to the deviation.
