Abstract:

Transportation infrastructure provides for vehicle-to-infrastructure (V2I) communication over a vehicle-to-everything (V2X) communication network with a V2X transceiver of a vehicle in accordance with a subscription level defining a level of access of the vehicle to data services of a cellular network. An interface controller operates as a gateway between the cellular network and the V2X communication network. A vehicle includes a transceiver for V2X communication. The transceiver provides for V2I communication over a V2X communication network with transportation infrastructure in accordance with a subscription level defining a level of access of the vehicle to a cellular network, and also provides for vehicle-to-vehicle (V2V) communication over the V2X communication network with other vehicles in accordance with the subscription level.

International Classification:

G08G 1/00
G08G 1/0967
G08B 25/01

Abstract:

Example vehicle communication management systems and methods are described. In one implementation, a communication management system determines whether a vehicle can communicate with an external system. If the vehicle is unable to communicate with the external system, the communication management system identifies a neighboring device that can communicate with the external system and communicates vehicle information to the neighboring device. The communication management system also requests the neighboring device to communicate the information, and other details from the neighboring device's perspective, to the external system.
