FIELD: transportation.
SUBSTANCE: method for detecting a rotating wheel (4) of a vehicle (1), which is driving on a roadway (2) in a driving direction (3) and wheels (4) of which are exposed laterally at least partially, comprising following steps: emitting an electromagnetic measurement beam (9) having a known time curve of frequency thereof to a first region above roadway (2) in a direction obliquely relative to vertical (V) and normally or obliquely relative to driving direction (3); receiving a reflected measurement beam (9) and recording time curve of frequencies thereof relative to known curve as a received frequency mixed curve (20); and detecting a continually ascending or descending band (22) of frequencies over a time period in received frequency mixed curve (20) as wheel (4).
EFFECT: high reliability of detecting rotating vehicle wheel.
