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, a vehicular micro cloud includes vehicles that are parked, vehicles that are traveling in different directions, infrastructure devices, or almost any endpoint that is within communication range of a member of the vehicular micro cloud. By comparison, a group of vehicles that exclude such endpoints as a requirement of being a member of the group are not vehicular micro clouds according to some embodiments.

In some embodiments, a vehicular micro cloud is operable to complete computational tasks itself, without delegation of these computational tasks to a cloud server, using the onboard vehicle computers of its members; this is an example of a vehicular micro cloud task according to some embodiments. In some embodiments, a group of vehicles which relies on a cloud server for its computational analysis, or the difficult parts of its computational analysis, is not a vehicular micro cloud. Although FIGS. 1B and 6 depict a server in an operating environment that includes the modification system, the server is an optional feature of the operating environment. An example of a preferred embodiment of the modification system does not include the server in the operating environment which includes the modification system.

In some embodiments, the modification system enables a group of vehicles to perform computationally expensive tasks that could not be completed by any one vehicle in isolation.
