Abstract

In a method for checking the auto-opening function of an actuator-operated clutch, the clutch is moved out of its closed position into its open position or out of its open position into its closed position by the actuator at a predetermined constant speed. During this movement of the clutch a force/distance curve is recorded; the point of the path at which the force is minimal is determined; and the clutch is moved to the determined path point by the actuator. The actuator is deactivated; and it is checked whether following deactivation of the actuator, the clutch returns into its open position in a predetermined manner.
