Abstract

The invention is directed to an arrangement for controlling an actuable element in a motor vehicle equipped with a drive unit. The arrangement includes an actuable element movable over a maximum possible operating range between two outermost limits including a normal operating work range within the limits; an electrically actuable actuating device for controlling the actuable element; a control unit for generating actuating signals for controlling the actuable element and for supplying the actuating signals to the actuating device; the control unit is adapted to generate the signals so as to cause the actuable element to move over most of the maximum possible operating range in a manner to prevent jammings with the actuable element being moved outside of the normal operating work range at least beyond one end of the normal operating work range; the actuable element being moved starting from a desired position for every possible direction of movement; and, the actuable element being moved at least at one of the following times: ahead of the start of the drive unit and after the drive unit has been switched off.
