US 6,472,836 B1 · Method and arrangement for electrically controlling and regulating the movement of an electrically operated aggregate of a motor vehicle

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.

Dependent claims

A method for electrically controlling and regulating movement of an electrically operated aggregate of a motor vehicle with an anti-jamming system, comprising:

measuring a correlation variable for an adjustment force of the electrically operated aggregate;
switching an adjusting movement of the electrically operated aggregate if the adjustment force exceeds a limit value which corresponds to the a maximum permissible jamming force;
and
filtering, on a temporal basis, the correlation value for the adjustment force of the electrically operated aggregate, and
deactivating the filtering when the motor vehicle is in a stationary state,
wherein a sensitivity of the anti-jamming system is increased automatically when the motor vehicle is in the stationary state.
