Abstract: During operation of a capacitive proximity sensor that is provided with at least two measuring electrodes, a first capacitance measurement variable and a second capacitance measurement variable are detected. The first capacitance measurement variable is correlated with the capacitance of at least one of the measuring electrodes to earth, while the second capacitance measurement variable is correlated with the capacitance between at least one of the measuring electrodes and at least one further measuring electrode. A change in the first capacitance measurement variable is evaluated together with a synchronous signal profile of the second capacitance measurement variable in order to distinguish a proximity of a conductor coupled electrically to earth from the proximity of dielectric matter. In this manner, a body part passing into the detection space of the proximity sensor can be distinguished effectively from other substances and objects, particularly water.

Abstract: In the course of an easily implemented anti-trap protection method for an adjustable vehicle part, a test variable is continuously determined by way of a distance sensor during the adjustment of the vehicle part. A direct anti-trap protection test determines, based on the test variable, whether an obstacle is detectable in the adjustment path of the vehicle part. The adjustment is stopped or reversed if necessary. An indirect anti-trap protection test determines on the basis of the same test variable whether the movement of the vehicle part has slowed down irregularly or come to a stop, and the adjustment is stopped or reversed if necessary. An associated anti-trap protection device includes an anti-trap protection control unit, which is designed for automatically performing the method.
