1. A method for receiving a data packet by a receiving vehicle, containing at least position data, in a transmission signal via a vehicle ad hoc network, the method comprising:
- filtering, by a first filter within a car-to-x transceiver of the receiving, vehicle, the received data packet on the basis of a first filter condition indicating that the received data packets are relevant to the receiving vehicle and outputting the filtered data packet to a processing device within the receiving vehicle for processing the filtered data packet, andfiltering, by a second, filter within the car-to-x transceiver of the receiving vehicle, the received data packet on the basis of a second filter condition indicating a predetermined physical distance such that;
a forwarding device within the car-to-x transceiver of the receiving vehicle forwards the filtered data packet to a further subscriber of the vehicle ad hoc network, in response to the receiving vehicle determining that the received data packets are transmitted from a subscriber vehicle located at least the predetermined physical distance away from the receiving vehicle, andthe forwarding device within the vehicle does not forward the filtered data packet to the further subscriber of the vehicle ad hoc network, in response to the receiving vehicle determining that the received data packets are transmitted from a subscriber vehicle located less than the predetermined physical distance away from the receiving vehicle.

9. An apparatus for receiving a data packet by a receiving vehicle, the data packet containing at least position data, in a transmission signal via a vehicle ad hoc network, the apparatus comprising:
-
a first filter within the receiving vehicle, the first filter filtering the received data packet on the basis of a first filter condition indicating that the received data packets are relevant to the receiving vehicle and outputting the filtered data packet to a processing device within the receiving vehicle for processing the filtered data packet, and a second filter within the receiving vehicle, the second filter filtering the received data packet on the basis of a second filter condition indicating a predetermined distance such that; a forwarding device within the vehicle forwards the filtered data packet to a further subscriber of the vehicle ad hoc network, in response to the receiving vehicle determining that the received data packets are transmitted from a subscriber vehicle located at least the predetermined physical distance away from the receiving vehicle, and the forwarding device within the vehicle does not forward the filtered data packet to the further subscriber of the vehicle ad hoc network, in response to the receiving vehicle determining that the received data packets are transmitted from a subscriber vehicle located less than the predetermined physical distance away from the receiving vehicle. - View Dependent Claims (10)
