Abstract

A vehicle identifies, from V2X messages received to a vehicle-to-everything (V2X) transceiver of a vehicle, message information from the received V2X messages indicative of locations of senders of the received V2X messages. The vehicle creates a virtual bounding box surrounding the vehicle based on a current location of the vehicle and a predefined size of the vehicle. The vehicle identifies whether any of the senders are located inside the vehicle using one or more factors, the factors including whether the locations of the senders of the received V2X messages are within the virtual bounding box. The configuration of the vehicle is updated based on whether any of the senders are located inside the vehicle.

First claim

What is claimed is:

1. A vehicle for detecting and remediating cellular vehicle-to-everything (C-V2X) device interference, comprising:
a vehicle-to-everything (V2X) transceiver configured to transmit and receive V2X messages;
a memory maintaining a V2X congestion tracking application; and
a processor programmed to execute the V2X congestion tracking application to perform operations including to
identify message information from the received V2X messages indicative of locations of senders of the received V2X messages,
create a virtual bounding box surrounding the vehicle based on a current location of the vehicle and a predefined size of the vehicle,
identify whether any of the senders are located inside the vehicle using one or more factors, the factors including whether the locations of the senders of the received V2X messages are within the virtual bounding box, and
update the configuration of the vehicle based on whether any of the senders are located inside the vehicle.

2. The vehicle of claim 1 , wherein the message information from the received V2X messages includes data layer information included in fields of the V2X messages, the data layer information including latitude, longitude, and elevation.

3. The vehicle of claim 2 , wherein the data layer information further includes positional accuracy information, the positional accuracy information including semi major axis accuracy, semi minor axis accuracy and semi major axis orientation.

4. The vehicle of claim 2 , wherein the message information includes physical layer information including one or more of: received signal strength indication (RSSI), reference signal received quality (RSRQ), reference signal received power (RSRP), and/or signal to interference plus noise ratio (SINR), and the identification of whether any of the senders are located inside the vehicle includes consideration of both the physical layer information and the data layer information.

5. The vehicle of claim 1 , wherein to update the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, to send a notification for display on a human-machine interface (HMI) of the vehicle, the notification indicating one or more of: a request to turn off V2X messaging from the senders located inside the vehicle, an indication that V2X features of the vehicle are being disabled due to the senders located inside the vehicle, or information that to cause the HMI to display an radio frequency (RF) heat map of the vehicle and/or identified locations of the senders that are inside the bounding box.

6. The vehicle of claim 5 , wherein to update the configuration of the vehicle includes:
responsive to determining that there are no senders located inside the vehicle and that V2X features were disabled, sending a second notification for display on the HMI of the vehicle, the second notification indicating that the V2X features of the vehicle are no longer being disabled.

7. The vehicle of claim 1 , wherein to update the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, discontinue sending of V2X messages or increase a period of time between transmission of V2X messages from the V2X transceiver; and
responsive to determining that there are no senders located inside the vehicle, reenable sending of the V2X messages or decrease the period of time between transmission of V2X messages from the V2X transceiver.

8. The vehicle of claim 7 , wherein to update the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, send special V2X messages configured to cause recipient senders located inside the vehicle to discontinue sending V2X messages; and
responsive to determining that there are no longer senders located inside the vehicle, discontinue sending the special V2X messages.

9. A method for detecting and remediating cellular vehicle-to-everything (C-V2X) device interference, comprising:
identifying, from V2X messages received to a vehicle-to-everything (V2X) transceiver of a vehicle, message information from the received V2X messages indicative of locations of senders of the received V2X messages;
creating a virtual bounding box surrounding the vehicle based on a current location of the vehicle and a predefined size of the vehicle;
identifying whether any of the senders are located inside the vehicle using one or more factors, the factors including whether the locations of the senders of the received V2X messages are within the virtual bounding box; and
updating the configuration of the vehicle based on whether any of the senders are located inside the vehicle.

10. The method of claim 9 , wherein the message information from the received V2X messages includes data layer information included in fields of the V2X messages, the data layer information including latitude, longitude, and elevation.

11. The method of claim 10 , wherein the data layer information further includes positional accuracy information, the positional accuracy information including semi major axis accuracy, semi minor axis accuracy and semi major axis orientation.

12. The method of claim 10 , wherein the message information includes physical layer information including one or more of: received signal strength indication (RSSI), reference signal received quality (RSRQ), reference signal received power (RSRP), and/or signal to interference plus noise ratio (SINR), and the identification of whether any of the senders are located inside the vehicle includes consideration of both the physical layer information and the data layer information.

13. The method of claim 9 , wherein updating the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, sending a notification for display on a human-machine interface (HMI) of the vehicle, the notification indicating one or more of: a request to turn off V2X messaging from the senders located inside the vehicle, an indication that V2X features of the vehicle are being disabled due to the senders located inside the vehicle, or information that to cause the HMI to display an radio frequency (RF) heat map of the vehicle and/or identified locations of the senders that are inside the bounding box.

14. The method of claim 13 , wherein updating the configuration of the vehicle includes:
responsive to determining that there are no senders located inside the vehicle and that V2X features were disabled, sending a second notification for display on the HMI of the vehicle, the second notification indicating that the V2X features of the vehicle are no longer being disabled.

15. The method of claim 9 , wherein updating the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, discontinuing sending of V2X messages or increase a period of time between transmission of V2X messages from the V2X transceiver; and
responsive to determining that there are no senders located inside the vehicle, reenabling sending of the V2X messages or decrease the period of time between transmission of V2X messages from the V2X transceiver.

16. The method of claim 15 , wherein updating the configuration of the vehicle includes:
responsive to determining that there are senders located inside the vehicle, sending special V2X messages configured to cause recipient senders located inside the vehicle to discontinue sending V2X messages; and
responsive to determining that there are no longer senders located inside
