Method for detecting wheels of a vehicle that is traveling on a roadway in a travel direction and the wheels of which are at least partially exposed laterally. The method including: emitting an electromagnetic measurement beam lobe with a known temporal progression of frequency from the side of the roadway onto an area of the roadway and at a slant with respect to the travel direction, receiving the measurement beam lobe reflected by a passing vehicle and recording the temporal progression, relative to the known progression, of all of its frequencies, and during the passage of a vehicle, detecting a frequency spread appearing in the recorded progression and exceeding a predetermined spread magnitude, as a wheel. |
