A method for localising an on-board unit, which has a radio transceiver and an identifier, to a predefined area around a radio beacon, comprising the following steps: a)storing the identifier and an associated radio property in a database; b)sending a first request; c) receiving a first response from an on-board unit; d)determining, from the database, the radio property of the transceiver associated with the received identifier; and e) localising the on-board unit in the predefined area; wherein: the steps b) to e) are repeated, for each run-through of the steps b) to e), a localisation result is stored in a presence list, and the localising is verified when the number of the positive localisation results exceeds a threshold value. |
