Disclosed is a method for positioning a mobile unit in a motor vehicle. The mobile unit is driven by an external force and equipped with an electronic jamming protection device. A tactile input unit is provided for positioning the mobile unit. An occupied position of the mobile unit is stored under certain conditions, whereby said stored position is automatically approached when the tactile unit is correspondingly operated.

Method for positioning a mobile unit in a motor vehicle

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.

Disclosed is a method for identifying pinching situations in a motor-driven displacing device. During a displacing process along an actuating direction, values (W(n) to (W(n&#x2212;m)) of a quantity (), which characterizes the currently occurring displacing force, or a quantity derived therefrom are determined and stored, and a quantity () that characterizes the pinching force of the displacing device is determined on the basis of at least two stored values (W(n) to (W(n&#x2212;m)). At least two measured values (W(n) to W(n&#x2212;m)) of the quantity (), which characterizes the displacing force, or of a quantity, which is derived from these values (W(n) to W(n&#x2212;m)), are compared with one another with regard to the time at which they are recorded, and are weighted according to the time at which they are recorded, wherein the quantity () that characterizes the pinching force is determined on the basis of the weighted values and is compared with an initiating threshold, and when this initiated threshold is exceeded, the displacing process is stopped and/or the actuation direction is reversed.
