Abstract

The disclosure describes embodiments for modifying an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication. In some embodiments, a method includes receiving, by a V2X receiver, a V2X message including context data that describes a context of a V2X transmitter in an environment, wherein the V2X receiver is not sufficiently able to identify the V2X transmitter as an originator of the V2X message within the environment. The method includes determining, by the V2X receiver, digital data describing an identity of the V2X transmitter as the originator of the V2X message within the environment based on the context data. The method includes modifying the operation of the vehicle component of the V2X receiver based on the digital data describing the identity of the V2X transmitter. The vehicle component includes, for example, one or more of an autonomous driving system and an Advanced Driver Assistance System (ADAS system).

Claims (37)

1. A method for modifying an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication, the method comprising:

receiving, by a V2X receiver, a V2X message including context data that describes a context of a V2X transmitter in an environment, wherein the V2X receiver is not sufficiently able to identify the V2X transmitter as an originator of the V2X message within the environment;

determining, by the V2X receiver, digital data describing an identity of the V2X transmitter as the originator of the V2X message within the environment based on the context data; and

modifying the operation of the vehicle component of the V2X receiver based on the digital data describing the identity of the V2X transmitter.

2. The method of claim 1 , wherein:

the environment is a roadway environment that includes the ego vehicle and a remote vehicle that receives the V2X message; and

the context data further describes a context of an ego vehicle within the roadway environment.

3. The method of claim 1 , wherein the V2X message is not one of the following: a WiFi message; a 3G message; a 4G message; a 5G message; a Long-Term Evolution (LTE) message; a millimeter wave communication message; a Bluetooth message; and a satellite communication.

4. The method of claim 1 , wherein the V2X message is a Basic Safety Message.

5. The method of claim 1 , wherein the context data describes a location of the V2X transmitter with an accuracy of substantially plus or minus half a width of a roadway which is being traveled by the V2X transmitter.

6. The method of claim 1 , wherein the V2X transmitter is an ego vehicle.

7. The method of claim 1 , wherein the V2X receiver is an autonomous vehicle.

8. A system for modifying an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication, the system included in a V2X receiver and comprising:

a processor; and

a non-transitory memory communicatively coupled to the processor, wherein the non-transitory memory stores computer code that is operable, when executed by the processor, to cause the processor to execute steps comprising:

receiving a V2X message including context data that describes a context of a V2X transmitter in an environment, wherein the V2X receiver is not sufficiently able to identify the V2X transmitter as an originator of the V2X message within the environment;

determining digital data describing an identity of the V2X transmitter as the originator of the V2X message within the environment based on the context data; and

modifying the operation of the vehicle component of the V2X receiver based on the digital data describing the identity of the V2X transmitter.

9. The system of claim 8 , wherein:

the environment is a roadway environment that includes the ego vehicle and a remote vehicle that receives the V2X message; and

the context data further describes a context of an ego vehicle within the roadway environment.

10. The system of claim 8 , wherein the V2X message is not one of the following: a WiFi message; a 3G message; a 4G message; a 5G message; a Long-Term Evolution (LTE) message; a millimeter wave communication message; a Bluetooth message; and a satellite communication.

11. The system of claim 8 , wherein the V2X message is a Basic Safety Message.

12. The system of claim 8 , wherein the context data describes a location of the V2X transmitter with an accuracy of substantially plus or minus half a width of a roadway which is being traveled by the V2X transmitter.

13. The system of claim 8 , wherein the V2X transmitter is an ego vehicle.

14. The system of claim 8 , wherein the V2X receiver is an autonomous vehicle.

15. A computer program product operable to modify an operation of a vehicle component based on a Vehicle-to-Everything (V2X) communication, wherein the computer program product comprises a non-transitory memory storing instructions that, when executed by a processor of a V2X receiver, cause the processor to perform operations comprising:

receiving a V2X message including context data that describes a context of a V2X transmitter in an environment, wherein the V2X receiver is not sufficiently able to identify the V2X transmitter as an originator of the V2X message within the environment;

determining digital data describing an identity of the V2X transmitter as the originator of the V2X message within the environment based on the context data; and

modifying the operation of the vehicle component of the V2X receiver based on the digital data describing the identity of the V2X transmitter.

16. The computer program product of claim 15 , wherein:

the environment is a roadway environment that includes the ego vehicle and a remote vehicle that receives the V2X message; and

the context data further describes a context of an ego vehicle within the roadway environment.

17. The computer program product of claim 15 , wherein the V2X message is not one of the following: a WiFi message; a 3G message; a 4G message; a 5G message; a Long-Term Evolution (LTE) message; a millimeter wave communication message; a Bluetooth message; and a satellite communication.

18. The computer program product of claim 15 , wherein the context data describes a location of the V2X transmitter with an accuracy of substantially plus or minus half a width of a roadway which is being traveled by the V2X transmitter.

19. The computer program product of claim 15 , wherein the V2X transmitter is an ego vehicle.

20. The computer program product of claim 15 , wherein the V2X receiver is an autonomous vehicle.
