Abstract
A method and apparatus for electrically controlling and regulating the movement of an electrically operated aggregate of a motor vehicle, such as a window lifter or sliding roof. A correlation variable for the adjustment force of the aggregate is measured for the purpose of anti-jamming protection. An adjusting movement is switched off or reversed if the adjustment force exceeds a limit value which corresponds to the maximum permissible jamming force. The sensitivity of the anti-jamming system is automatically raised when the motor vehicle is at a standstill. A rough road filter is preferably deactivated so that in the event of jamming, an adjusting movement is switched off or reversed without any time delay. The highest possible level of safety is provided using anti-jamming protection when the vehicle is at a standstill.
