Abstract
Official abstract text for this publication.
A capacitive proximity sensor for a motor vehicle contains a transmission electrode for producing a measurement field and a reception electrode for detecting at least part of the measurement field. Furthermore, the proximity sensor contains a screen electrode that is disposed to form the measurement field between the transmission electrode and the reception electrode. The proximity sensor is in particular provided for use in a collision protection device for the motor vehicle.
First claim

1 . A capacitive proximity sensor for a motor vehicle, the capacitive proximity sensor comprising: a transmission electrode for producing a measurement field; a reception electrode for detecting at least part of the measurement field; and a screen electrode disposed to form the measurement field between said transmission electrode and said reception electrode. 2 . The capacitive proximity sensor according to claim 1 , wherein said screen electrode is connected to a reference potential. 3 . The capacitive proximity sensor according to claim 1 , wherein said screen electrode is a cable shield of a shielded connecting line of said transmission electrode or said reception electrode. 4 . The capacitive proximity sensor according to claim 1 , wherein said transmission electrode and said reception electrode are of an elongated form. 5 . The capacitive proximity sensor according to claim 1 , further comprising: predefined holding elements; and a base support, on said base support said transmission electrode, said reception electrode and said screen electrode are held by said predefined holding elements. 6 . A collision protection device for a motor vehicle, the collision protection device comprising: a capacitive proximity sensor containing a transmission electrode for producing a measurement field, a reception electrode for detecting at least part of the measurement field, and a screen electrode disposed to form the measurement field between said transmission electrode and said reception electrode; and a control unit configured to infer a presence of an object within a region upstream of a vehicle part that is monitored using the measurement field by using the part of the measurement field that is detected by said reception electrode. 7 . A motor vehicle, comprising: a capacitive proximity sensor containing a transmission electrode for producing a measurement field, a reception electrode for detecting at least part of the measurement field, and a screen electrode disposed to form the measurement field between said transmission electrode and said reception electrode.
