Method for Detecting a rotating Wheel of a vehicle by the Evaluation of the Doppler shift of a measuring Beam which is emitted by a Detection Unit passed by the vehicle and which is reflected in the Wheel and returns in the form of Displacement at the position where: (R) The WheelThe vehicle includes an on-board unit that can establish a radio transceiver has a known location (L) in the Detection Unit

摘要

The method involves measuring the direction and distance of an onboard unit (15) from a transceiver (24) on the basis of wireless communication (23) between the onboard unit and the transceiver. The radiation direction or radiation position of a measuring beam (6) is controlled based on the measured direction and distance and taking into consideration the relative position and location. The relative position is measured by a stationary or mobile control device and is stored in the onboard unit by wireless communication.
