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.

說明書

In some embodiments, the ADAS system 183 or the autonomous driving system 184 of the first endpoint 101 provides a command to the communication unit 145 of the first endpoint 101 to transmit a mmWave message to another endpoint (e.g., the second endpoint 103 or the third endpoint 104). Responsive to receiving the command, the intention detection module 204 determines that a mmWave message is desired to be exchanged by the first endpoint 101 with the other endpoint. The intention detection module 204 may notify the scenario module 206 of the first endpoint's intention to exchange the mmWave message, which causes the scenario module 206 to generate scenario data as described below.

The scenario module 206 can be software including routines that, when executed by the processor 125, cause the processor 125 to generate scenario data. In some embodiments, the scenario module 206 can be a set of instructions stored in the memory 127 of the computer system 200 and can be accessible and executable by the processor 125. The scenario module 206 may be adapted for cooperation and communication with the processor 125 and other components of the computer system 200 via a signal line 281.
