Abstract:
1. A method for detecting a disengagement of a clutch in a flap drive, wherein the clutch couples a drive motor to an adjustable flap such that the flap can be adjusted by the drive motor, and wherein the coupling action between the drive motor and the flap is eliminated if a force or a torque acting on the flap exceeds a maximum value, the method comprising: (a) detecting, by a control unit, data regarding an adjustment speed of the drive motor; (b) determining, by the control unit, a gradient of the adjustment speed based on the data regarding the adjustment speed; and (c) detecting, by the control unit, a disengagement of the clutch by determining whether the predetermined gradient exceeds or undershoots a predetermined gradient threshold value.
