Zusammenfassung:	In a method for ascertaining whether a target object can be driven over by the controlled motor vehicle, with the aid of frequency-modulated radar signals of a radar sensor, amplitude ratios between received radar signals reflected from the target object are utilized, the received radar signals corresponding to signals which have been transmitted in different frequency ranges. Based on the amplitude ratios, an occurrence of interference between (i) a first radar signal propagation path between the radar sensor and the target object and (ii) a second propagation path with additional reflection from a road is detected, and based on the detection of an occurrence of interference it is ascertained whether the object can be driven over.
