Abstract

A method for checking communication messages in vehicle-to-environment communication, a communication message being received and evaluated, and to a receiver suitable for carrying out the method. In order to check a communication message, a feature obtained from the content of the communication message is compared to a feature that corresponds to said feature, the corresponding feature being obtained by a sensory system that is independent of the vehicle-to-environment communication.

Claims

1-9. -9. (canceled)

10. A method for checking communication messages in a vehicle-to-environment communication, comprising:

receiving a communication message by a receiver;

evaluating the communication message;

obtaining a feature from the communication message;

obtaining a corresponding feature by a sensor system that is independent from the vehicle-to-environment communication that corresponds to the obtained feature; and

comparing the obtained feature with the corresponding feature.

11. The method as claimed in claim 10,

wherein the feature obtained from the communication message is at least one of a transmitted position of a participating transmitter and a speed of the participating transmitter, and

wherein the least one of the transmitted position of the participating transmitter and the speed of the participating transmitter is determinable by the independent sensor system.

12. The method as claimed in claim 11, wherein the feature obtained from the communication message is a type of the participating transmitter, and that the type of the participating transmitter is determinable by the independent sensor system.

13. The method as claimed in claim 11, wherein the feature obtained from the communication message is a transmitted status of the participating transmitter, and that the status of the participating transmitter is determinable by the independent sensor system.

14. The method as claimed in claim 10, wherein, in the absence of a correspondence between the content and the corresponding feature, a message is generated by the receiver that at least one of allows inferences to be made concerning an identity of the transmitter and enables identification of the transmitter.

15. A receiver configured to check a communication message in a vehicle-to-environment communication in which the communication message is received and evaluated, wherein the receiver comprises:

a receiver that receives the communication message containing a feature in the vehicle-to-environment communication the;

a sensor that is independent from the vehicle-to-environment communication and configured to obtain a corresponding feature that corresponds to the feature in the vehicle-to-environment communication; and

a computing unit, wherein the computing unit is configured to;

evaluate the communication message;

obtain the feature from the communication message; and

compare the feature from the communication message with the corresponding feature.

16. The receiver as claimed in claim 15, wherein the sensor device comprises at least one of a camera, a radio direction finding device, and a speed-measuring device.

17. The receiver as claimed in claim 15, wherein the receiver is a mobile stationary unit.

18. The receiver as claimed in claim 15, wherein the receiver is integrated into a participant in the vehicle-to-environment communication with further functions.

19. The receiver as claimed in claim 16, wherein the receiver is a mobile stationary unit.
