Claims

A method for detecting and mitigating radio frequency (RF) interference in a first vehicle, the method comprising:
detecting one or more vehicles within a threshold distance of the first vehicle , the step of detecting the one or more vehicles within a threshold distance of the first vehicle; but,
receiving one or more return signals from a sensor of the first vehicle;
determining a distance and speed of the one or more vehicles based on the one or more return signals, the speed comprising a speed component and a direction component;
determining the threshold distance based at least in part on the determined velocity;
determining that the distance is less than the threshold distance;
determining the location and motion state of the one or more vehicles in response to the detection;
the potential of at least a portion of the wireless network of the first vehicle by the one or more vehicles based at least in part on the determined location and the determined motion state of the one or more vehicles; determining RF interference;
implementing an interference mitigation technique based at least in part on the determined location and the determined motion state of the one or more vehicles .

2. The method of claim 1 , wherein the sensor of the first vehicle comprises a radar, LIDAR, camera, ultrasonic sensor, or any combination thereof.

2. The method of claim 1, wherein the step of detecting the one or more vehicles within a threshold distance of the first vehicle includes receiving one or more V2X messages.

said step of determining said location and said motion state of said one or more vehicles;
receiving the one or more V2X messages from the one or more vehicles;
and determining a location, heading , and speed of the one or more vehicles from the one or more V2X messages.

5. The method of claim 4 , further comprising determining a time of the potential RF interference based at least in part on the location, heading, and speed of the one or more vehicles.

determining a portion of the wireless network of the first vehicle that is susceptible to the potential RF interference based at least in part on the location, the heading, and the speed of the one or more vehicles; 5. The method of claim 4 , further comprising:

The interference mitigation technique includes:
increasing or decreasing the power of a wireless transmitter of the wireless network;
changing the frequency or channel of a wireless transmitter of the wireless network;
increasing or decreasing the gain level of a wireless receiver of the wireless network; or
activating one or more additional wireless transmitters of the wireless network;
or any combination thereof.

memory and
one or more processing units communicatively coupled to the memory, the one or more processing units comprising:
detecting one or more vehicles within a threshold distance of a first vehicle, the detecting the one or more vehicles within a threshold distance of the first vehicle; ,
receiving one or more return signals from a sensor of the first vehicle;
determining a distance and velocity of the one or more vehicles based on the one or more return signals, the velocity including a speed component and a directional component;
determining the threshold distance based at least in part on the determined velocity;
determining that the distance is less than the threshold distance;
In response to the detection, determining the location and motion state of the one or more vehicles;
the potential of at least a portion of the wireless network of the first vehicle by the one or more vehicles based at least in part on the determined location and the determined motion state of the one or more vehicles; determining radio frequency (RF) interference;
