1. A position determination device located in a vehicle, the position determination device having:

  • a position determination unit in the vehicle, including sensors and a global navigation system satellite (GNSS) receiver for determining a position of the vehicle;

    a communication unit in the vehicle, including a receiver for receiving validation data which includes position data of a plurality of adjacent vehicles or of a plurality of adjacent infrastructure devices; and

    a control unit in the vehicle, including a processor for carrying out a validation of the position determined by the position determination unit by comparing the position determined by the position determination unit to the position data included in the validation data,wherein the processor is configured to compare the position of the vehicle determined by the position determination unit to the position data of the adjacent vehicle or the adjacent infrastructure device included in the validation data, andwherein the processor is configured to;

    1) compare the position data of the plurality of vehicles or the plurality of infrastructure devices to each other, and filter out the position data from the validation data that do not match,2) validate the position determined by the position determination unit when the comparison between the position determined by the position determination unit and the position data included in the validation data is within a communication range indicating that the position determined by the position determination unit is probable, the validated position used by at least one of a safety system or an assistance system located in the vehicle, and3) invalidate the position determined by the position determination unit when the comparison between the position determined by the position determination unit and the position data included in the validation data is outside of the communication range indicating that the position determined by the position determination unit is improbable, the invalidated position filtered out and not used by the at least one of the safety system or the assistance system located in the vehicle.
