摘要

The disclosure includes embodiments for modifying a vehicle-to-everything (V2X) radio of an ego vehicle that is a connected vehicle. In some embodiments, a method includes analyzing, by a machine learning module executed by a processor, a local dynamic map generated by the ego vehicle to determine schedule data describing a schedule for the ego vehicle to transmit a millimeter wave (mmWave) message to a remote vehicle. The method includes transmitting a V2X message including the schedule data for receipt by the remote vehicle so that the remote vehicle has access to the schedule. The method includes modifying an operation of the V2X radio of the ego vehicle based on the schedule so that the V2X radio transmits the mmWave message to the remote vehicle in compliance with the schedule. The method includes transmitting the mmWave message to the remote vehicle in compliance with the schedule.

For example, the scenario module 206 generates location data describing a geographic location of the first endpoint 101 and time data describing a time when the first endpoint is present at the geographic location based on sensor data recorded by the GPS unit 170. The scenario module 206 generates speed data describing a speed, an acceleration, or a combination thereof of the first endpoint 101 based on sensor data recorded by an accelerometer. The scenario module 206 generates weather data describing one or more weather conditions at the geographic location based on sensor data recorded by a camera, a LIDAR sensor, a thermostat, and any other types of sensors. Furthermore, based on the sensor data recorded by the sensor set 182, the scenario module 206 may also generate: relative data describing one or more of a location of the other endpoint relative to the first endpoint 101, a speed of the other endpoint relative to the first endpoint 101 and an acceleration of the other endpoint relative to the first endpoint 101; and endpoint data describing one or more of a make and model of the other endpoint and a make and model of the first endpoint 101.

The report module 207 can be software including routines that, when executed by the processor 125, cause the processor 125 to generate a beam report message. In some embodiments, the report module 207 can be stored in the memory 127 of the computer system 200 and can be accessible and executable by the processor 125. The report module 207 may be adapted for cooperation and communication with the processor 125 and other components of the computer system 200 via a signal line 226.
