Method for correcting a coupling actuator characteristic curve

A method for correcting an actuator characteristic 32 of a clutch actuator 16 for a friction clutch 14 of a vehicle transmission 12 after the commissioning thereof. The actuator characteristic 32 relates a first desired variable, such as a desired clutch pressure, to a second desired variable, such...

Zusammenfassung:	A method for correcting an actuator characteristic 32 of a clutch actuator 16 for a friction clutch 14 of a vehicle transmission 12 after the commissioning thereof. The actuator characteristic 32 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 (KP; VB) of the friction clutch 14; detecting a deviation between the first desired variable and an actual variable of the friction clutch 14; and setting up a correction function 34 for the actuator characteristic 32 according to the deviation.
