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

The ego vehicle and the remote vehicles may be human-driven vehicles, autonomous vehicles, or a combination of human-driven vehicles and autonomous vehicles. In some embodiments, the ego vehicle and the remote vehicles may be equipped with DSRC equipment such as a GPS unit that has lane-level accuracy and a DSRC radio that is capable of transmitting DSRC messages.

In some embodiments, the ego vehicle and some or all of the remote vehicles include their own instance of a modification system. For example, in addition to the ego vehicle, some or all of the remote vehicles include an onboard unit having an instance of the modification system installed therein.

In some embodiments, the ego vehicle and one or more of the remote vehicles are members of a vehicular micro cloud. In some embodiments, the remote vehicles are members of a vehicular micro cloud, but the ego vehicle is not a member of the vehicular micro cloud. In some embodiments, the ego vehicle and some, but not all, of the remote vehicles are members of the vehicular micro cloud. In some embodiments, the ego vehicle and some or all of the remote vehicles are members of the same vehicular macro cloud but not the same vehicular micro cloud, meaning that they are members of various vehicular micro clouds that are all members of the same vehicular macro cloud so that they are still interrelated to one another by the vehicular macro cloud.

An example of a vehicular micro cloud according to some embodiments includes the vehicular micro cloud 194 depicted in FIG. 6.
