Abstract
Disclosed is a circuit arrangement for electrically controlling and/or regulating the movement of an electrically driven unit (), especially a window lifter or sliding roof of a motor vehicle, and to a method for operating said circuit arrangement. According to the invention, a jamming protection System is characterized in that a correlation variable (K) for the adjusting force of the unit () is measured and the adjusting movement is stopped or reversed in order to prevent jamming if the correlation variable (K) for the adjusting force exceeds a threshold value that corresponding to a predetermined jamming force. A filter () is used for temporally filtering the correlation variable (K) for the adjusting force of the unit. The invention is characterized in that the filter parameters (), especially the cutoff frequency (fg) and/or the order of the filter (), can be controlled.
