Abstract

A method for processing vehicle-to-X messages in a processing module and a method for processing vehicle-to-X messages in a control module. In the course of this messages are checked in a specified checking sequence.

First claim

The invention claimed is:

1. A method for processing vehicle-to-X messages in a processing module, comprising:
receiving a quantity of vehicle-to-X messages,
storing the vehicle-to-X messages in a buffer memory,
specifying a checking sequence for the vehicle-to-X messages, and
performing a verification of the vehicle-to-X messages in accordance with the checking sequence.

2. The method according to claim 1 ,
wherein the checking sequence is specified on the basis of prioritization information.

3. The method according to claim 2 , further comprising:
receiving a quantity of prioritization information for the stored vehicle-to-X messages from a control module.

4. The method according to claim 3 , further comprising:
in response to the performance of a verification for a vehicle-to-X message, removing the vehicle-to-X message from the buffer memory and/or immediately sending a result of the verification to the control module.

5. The method according to claim 3 , further comprising:
specifying of the prioritization information by the processing module.

6. The method according to claim 3 , wherein the prioritization information indicates numerical and/or quantitative values for the vehicle-to-X messages.

7. The method according to claim 2 , further comprising:
specifying of the prioritization information by the processing module.

8. The method according to claim 7 , wherein the prioritization information indicates numerical and/or quantitative values for the vehicle-to-X messages.

9. The method according to claim 2 ,
wherein the prioritization information indicates numerical and/or quantitative priority values for the vehicle-to-X messages.

10. The method according to claim 1 , further comprising:
forwarding the vehicle-to-X messages to at least one control module.

11. The method according to claim 10 ,
wherein the vehicle-to-X messages are forwarded without particular components to be detached.

12. The method according to claim 11 , further comprising:
receiving a check request from the control module for at least one of the vehicle-to-X messages and, in response thereto, performing a verification of said vehicle-to-X message and sending a result of the verification to the control module.

13. The method according to claim 10 , further comprising:
receiving a check request from the control module for at least one of the vehicle-to-X messages and, in response thereto, performing a verification of said vehicle-to-X message and sending a result of the verification to the control module.

14. The method according to claim 13 ,
wherein when a check request for a message which has already been verified is received a result of this verification is sent to the control module.

15. The method according to claim 14 , wherein an identifier for identifying the vehicle-to-X message is saved for each message stored in the buffer memory, and wherein a particular check request contains a particular identifier for the vehicle-to-X message to be verified.

16. The method according to claim 13 ,
wherein an identifier for identifying the vehicle-to-X message is saved for each message stored in the buffer memory, and
wherein a particular check request contains a particular identifier for the vehicle-to-X message to be verified.

17. The method according to claim 1 , further comprising:
performing pre-processing of the vehicle-to-X messages,
wherein depending on the pre-processing only a part of the vehicle-to-X messages is stored and/or sent.

18. The method according to claim 1 further comprising:
detecting a low system load of the processing module, wherein
the verification of stored vehicle-to-X messages is performed in response to the detection of a low system load.

19. A method for processing vehicle-to-X messages in a control module, comprising:
receiving a quantity of vehicle-to-X messages from a processing module, and
determining and sending the particular prioritization information for the vehicle-to-X messages to the processing module.

20. The method according to claim 19 , further comprising:
determining for each of the vehicle-to-X messages whether the particular vehicle-to-X message is to be verified and, in response to the fact that a particular vehicle-to-X message is to be verified, sending a check request for this vehicle-to-X message to the processing module.
