Abstract

In various embodiments, a vehicle-to-everything (V2X) processing device detecting a misbehavior condition in a system of the vehicle, and prevent the vehicle from sending a V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition in the system of the vehicle. In some embodiments, the V2X processing device may receive information from a plurality of information sources of the vehicle, and may detect the misbehavior condition in the system of the vehicle by performing a cross-check of information received from the plurality of information sources of the vehicle to detect an inconsistency within the received information.

First claim

What is claimed is:

1. A method of misbehavior condition management performed by a vehicle-to-everything (V2X) processing device of a vehicle, comprising:
detecting a misbehavior condition of a system of the vehicle; and
preventing the vehicle from sending a V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

2. The method of claim 1 , further comprising transmitting to a management entity a misbehavior report indicating the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

3. The method of claim 1 , wherein detecting a misbehavior condition of a system of the vehicle comprises:
receiving information from a plurality of information sources of the vehicle; and
detecting the misbehavior condition of the system of the vehicle by performing a cross-check of information received from the plurality of information sources of the vehicle to detect an inconsistency within the received information.

4. The method of claim 3 , wherein the plurality of information sources of the vehicle comprises one or more of an in-vehicle network, a vehicle sensor, a vehicle actuator, radio frequency (RF) module, or a previously transmitted V2X message.

5. The method of claim 1 , wherein preventing the vehicle from sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle comprises:
identifying a value that is received from a vehicle element and that is associated with the detected misbehavior condition; and
preventing the identified value from being used in a V2X message to be sent by the vehicle.

6. The method of claim 1 , wherein preventing the vehicle from sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle comprises:
identifying a vehicle element that is a source of the detected misbehavior condition; and
preventing information from the identified vehicle element from being used in a V2X message to be sent by the vehicle.

7. The method of claim 6 , further comprising:
adding the identified vehicle element to a blocking list indicating that information from the identified vehicle element should not be used for generating V2X messages.

8. The method of claim 1 , wherein:
detecting a misbehavior condition of a system of the vehicle comprises detecting an inconsistency between a radio frequency (RF) profile of an RF module and an RF module transmit configuration; and
preventing the vehicle from sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle comprises preventing the vehicle from sending the V2X message using the RF module transmit configuration.

9. The method of claim 1 , further comprising re-calibrating one or more sensors of the vehicle in response to detecting the misbehavior condition of the system of the vehicle.

10. A vehicle-to-everything (V2X) processing device, comprising:
a processor configured with processor-executable instructions to:
detect a misbehavior condition of a system of a vehicle; and
prevent sending a V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

11. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to transmit to a management entity a misbehavior report indicating the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

12. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to detect a misbehavior condition of a system of the vehicle by:
receiving information from a plurality of information sources of the vehicle; and
detecting the misbehavior condition of the system of the vehicle by performing a cross-check of information received from the plurality of information sources of the vehicle to detect an inconsistency within the received information.

13. The V2X processing device of claim 12 , wherein the plurality of information sources of the vehicle comprises one or more of an in-vehicle network, a vehicle sensor, a vehicle actuator, radio frequency (RF) module, or a previously transmitted V2X message.

14. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to prevent sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle by:
identifying a value that is received from a vehicle element and that is associated with the detected misbehavior condition; and
preventing the identified value from being used in a V2X message to be sent by the vehicle.

15. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to prevent sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle by:
identifying a vehicle element that is a source of the detected misbehavior condition; and
preventing information from the identified vehicle element from being used in a V2X message to be sent by the vehicle.

16. The V2X processing device of claim 15 , further wherein the processor is further configured with processor-executable instructions to add the identified vehicle element to a blocking list indicating that information from the identified vehicle element should not be used for generating V2X messages.

17. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to:
detect a misbehavior condition of a system of the vehicle comprises by detecting an inconsistency between a radio frequency (RF) profile of an RF module profile and an RF module transmit configuration; and
prevent sending the V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle by preventing sending a V2X message using the RF module transmit configuration.

18. The V2X processing device of claim 10 , wherein the processor is further configured with processor-executable instructions to re-calibrate one or more sensors of the vehicle in response to detecting the misbehavior condition of the system of the vehicle.

19. A vehicle-to-everything (V2X) processing device, comprising:
means for detecting a misbehavior condition of a system of a vehicle; and
means for preventing the vehicle from sending a V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

20. The V2X processing device of claim 19 , further comprising means for transmitting to a management entity a misbehavior report indicating the detected misbehavior condition in response to detecting the misbehavior condition of the system of the vehicle.

21. The V2X processing device of claim 19 , wherein means for detecting a misbehavior condition of a system of the vehicle comprises:
means for receiving information from a plurality of information sources of the vehicle; and
