Anti-trapping device for a motor vehicle
First Claim
1. An anti-pinch device, comprising:
- a motor driving a pivotable actuating element of a motor vehicle about an axis of rotation;
a non-contact detection sensor which detects obstacles in a path of the actuating element with an electrode that generates an external electric field relative to a counter electrode, the electrode extending in a radial direction relative to the axis of rotation of the pivotable actuating element and being divided in the radial direction into a plurality of segments that are arranged successively further from the axis of rotation, each of which being evaluated separately and generates an interference signal; and
a control unit which controls the motor depending on an interference signal from one of the segments, wherein the control unit further controls the motor differently depending on which one of the segments the interference signal is received from, wherein the control unit further controls the motor differently depending on the distance of the segment from which the interference signal is received to the axis of rotation of the pivotable actuating element.

Abstract
The invention specifies an anti-trapping device, comprising a motor for driving a pivotable actuating element of a motor vehicle, a sensor for contactlessly identifying an obstacle in the way of the actuating element with an electrode, which has a plurality of segments for producing an external electrical field with respect to a mating electrode and a control unit. The electrode extends in a radial direction with respect to the pivotable actuating element and is split in the radial direction into the plurality of segments, which can each be evaluated separately for the purpose of generating an interference signal. The control unit is designed to drive the motor as a function of an interference signal from one of the segments. Such an anti-trapping device has particularly high flexibility when driving the pivotable actuating element if an obstacle in the way of the pivotable actuating element has been detected.
