<p>Described is a method for identifying a vehicle using a predetermined location, comprising: carrying, on the vehicle, an onboard unit that via radio repeatedly broadcasts status messages, which each indicate a current relative distance (A i) of the onboard unit from the predetermined location and a radio identifier (pID) that changes after each or several status messages; receiving at least one status message in a radio beacon; detecting a location usage of the vehicle by evaluating the at least one status message based on the relative distance (A i) indicated therein; transmitting an identification request from the radio beacon to that onboard unit which is addressed by way of the radio identifier (pID) from the at least one status message; receiving and conducting a legitimacy check of the identification request in the onboard unit and, if the request is legitimate, transmitting a unique identification (ulD) of the onboard unit to the radio beacon, the unique identification remaining the same over several changes of radio identifier (pID). Also described is a radio beacon and to an onboard unit for use with this method.</p> |
