INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Techniques described herein leverage existing localization sensors or V2X devices to detect one or more other vehicles that include wireless systems that can interfere with in-vehicle wireless networks. The localization sensors or V2X devices can provide information to determine a location, a heading, a speed, a size, and a type of other vehicles. This information can be used to determine a probability of network interference and allow the in-vehicle wireless networks to employ one or more techniques to mitigate the effects of the interference. The interference mitigation techniques can include increasing or decreasing transmitter power, changing a frequency or a channel of a wireless transmitter, or activating one or more additional transmitters as relays to improve reliability. ## Claims ### Claim 1 A method of detecting and mitigating radio frequency (RF) interference at a first vehicle, the method comprising: detecting one or more vehicles within a predetermined threshold distance of the first vehicle, wherein the detecting the one or more vehicles comprises: receiving one or more return signals from a sensor of the first vehicle, wherein the sensor comprises a radar, a LiDAR, a camera, an ultrasound sensor, or any combination thereof;
