VALIDATION OF A VEHICLE POSITION

In order to devise a method for validating a assumed position (P1) of a vehicle, a vehicle receiver (1) receives a V2X message (3) transmitted by a transmitter (2) and determines a position (p2) of the transmitter (2) from the V2X message, wherein local environmental geodata comprising positions of a number of stationary objects (O1, O2, O3, O4) is made available, a signal path (x) of the V2X message (3) is simulated on the basis of the transmitter position (p2) taking into account the environmental geodata and the assumed vehicle position (P1), and at least one simulated physical received signal property is determined from the simulated signal path (x) and the assumed vehicle position (P1). When receiving the V2X message, at least one actual physical received signal property of the V2X message (3) is determined, and the assumed vehicle position (P1) is validated if the at least one simulated physical received signal property differs from the at least one actual physical received signal property by less than a limit value (G).
