Abstract
In a method for operating an actuating device in a motor vehicle including the steps of measuring an actuating force exerted by the actuating drive, comparing the actuating force to a limit force, and reversing the actuating drive if the limit force is exceeded, provision is made that, while the motor vehicle is being driven, the measured values of the actuating force are filtered, prior to the comparison operation, in accordance with a first method, to suppress rapid changes in the actuating force on the basis of the path covered by the actuating drive, and, while the motor vehicle is at rest, with the engine turned off, in accordance with a second method where rapid changes are suppressed to a lesser extent than in the first method, or not filtered at all. A device for carrying out the method is specified.
