A method for characterizing an object in an environmental region of a motor vehicle by comparing a received signal of a distance sensor with a predetermined curve, sensor device and driver assistance system

摘要

The invention relates to a method for characterizing an object (8) in an environmental region (9) of a motor vehicle (1) in which a sensor signal is emitted by means of a distance sensor (4) and the sensor signal reflected by the object (8) is received Receiving signal (10) is determined, which describes a time course of amplitudes of the received sensor signal, a resonance curve (15) is determined, which describes the received signal (10) and the object (8) is characterized by a shape of the resonance curve (15), wherein the resonance curve (15) is determined in such a way that it describes a maximum (M) of the received signal (10), the shape of the resonance curve (15) is compared with a profile of the received signal (10) and, based on the comparison, a height of the object (10). 8) is estimated.
