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 this way, the data traffic between processing module and control module can be considerably reduced.

First claim

The invention claimed is:

1. A method for processing vehicle-to-x messages in a processing module, comprising:
receiving a number of vehicle-to-x messages,
storing the vehicle-to-x messages in a buffer memory,
forwarding the vehicle-to-x messages to at least one control module, and
receiving a checking request from the control module for at least one of the vehicle-to-x messages, in response performing a verification of the at least one vehicle-to-x message and sending a result of the verification to the at least one control module.

2. The method according to claim 1 , further comprising:
performing a preprocessing of the vehicle-to-x messages,
wherein as a function of the preprocessing only part of the vehicle-to-x messages is stored and/or sent.

3. The method according to claim 1 ,
wherein the vehicle-to-x messages are forwarded without their respective security parts that are to be detached.

4. The method according to claim 1 ,
wherein for each message stored in the buffer memory an identifier to identify the vehicle-to-x message is stored, and
wherein a respective checking request contains a respective identifier of the vehicle-to-x message to be verified.

5. The method according to claim 4 ,
wherein as the identifier of a respective vehicle-to-x message a component of the vehicle-to-x message can be used or a separate identifier is generated.

6. The method according to claim 1 , further comprising:
in response to performing 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 at least one control module.

7. A method for processing vehicle-to-x messages in a processing module, comprising:
receiving a number of vehicle-to-x messages,
storing the vehicle-to-x messages in a buffer memory,
forwarding the vehicle-to-x messages to at least one control module, and
identifying a low system load of the processing module, and in response performing a verification of the stored vehicle-to-x messages.

8. The method according to claim 7 , further comprising:
receiving an amount of prioritization information for the stored vehicle-to-x messages,
wherein during the verification in response to the low system load a sequence of vehicle-to-x messages to be verified is determined based on the prioritization information.

9. The method according to claim 8 ,
wherein upon receipt of a checking request for a message that has already been verified a result of this verification is sent to the at least one control module.

10. The method according to claim 7 ,
wherein upon receipt of a checking request for a message that has already been verified a result of this verification is sent to the control module.

11. A method for processing vehicle-to-x messages in a control module, comprising:
receiving a number of vehicle-to-x messages from a processing module, and
determining for each of the vehicle-to-x messages whether the respective vehicle-to-x-message is to be verified and in response to a respective vehicle-to-x message needing to be verified sending a checking request for this vehicle-to-x message to the processing module.

12. The method according to claim 11 , further comprising:
performing a decoding for the vehicle-to-x messages.

13. The method according to claim 12 , further comprising:
receiving respective results of a verification for the vehicle-to-x messages.

14. The method according to claim 11 , further comprising:
receiving respective results of a verification for the vehicle-to-x messages.

15. The method according to claim 11 , further comprising:
determining and sending respective prioritization information for the vehicle-to-x messages to the processing module.

16. The method according to claim 11 ,
wherein each checking request contains a respective identifier of the message to be verified.

17. The method according to claim 11 , further comprising:
performing an ASN.1 decoding for the vehicle-to-x messages.

18. A method for processing vehicle-to-x messages in a processing module and a control module, wherein
the processing module performs a method comprising:
receiving a number of vehicle-to-x messages,
storing the vehicle-to-x messages in a buffer memory,
forwarding the vehicle-to-x messages to at least one control module, and
receiving a checking request from the at least one control module for at least one of the vehicle-to-x messages, in response performing a verification of the at least one vehicle-to-x message and sending a result of the verification to the control module; and

the control module performs a method comprising:
receiving a number of vehicle-to-x messages from a processing module, and
determining for each of the at least one vehicle-to-x messages whether the respective vehicle-to-x-message is to be verified and in response to a respective vehicle-to-x message needing to be verified sending a checking request for this the at least one vehicle-to-x message to the processing module.
