Embodiment Construction

[0018] This application proposes a multi-V2X server communication architecture and a V2X communication solution for vehicles traveling across V2X service areas.

[0019] figure 2 Shown is the architecture or idea of ​​a V2X central server (V2X Center, V2X-C) alliance proposed by this application. figure 2 The V2X-C shown in is the server or node for the initial vehicle registration or account opening registration, which records the account opening or registration data of the vehicle, and also records the vehicle operation data. Optionally, V2X-C can provide vehicle management capabilities to agencies such as traffic police or highway supervision. Car companies or other third-party applications can also obtain vehicle operation data through this server. The V2X Regional Server (V2X Region, V2X-R) is a server or node that provides V2X services to vehicles. The V2X services provided include V2I services (such as traffic signal status push, traffic time push, etc.), V2V service...

Abstract

This application proposes a communication solution for the Internet of Vehicles, which is based on a V2X center server (V2X Center, V2X-C) alliance architecture or idea, and V2X-C nodes in multiple regions form V2X-C according to planning or self-organization In the alliance, the V2X-C nodes in the alliance exchange information about the V2X service areas they are responsible for. When a vehicle needs to obtain Internet of Vehicles services, it first connects to the V2X-C node it belongs to, and then the V2X-C node judges whether it is in the V2X service area covered by this V2X-C through the current location of the vehicle, and if so, according to the geographical location of the vehicle Location, allocate the V2X regional service node in the area where the vehicle is located to the vehicle, and send the access address of the V2X regional service node to the vehicle, if not, request the allocation of a V2X regional service node to other V2X-C nodes according to the geographical location of the vehicle, And pass the access information of the V2X regional service node to the vehicle, so that the vehicle can access the V2X server in the current area and enjoy the Internet of Vehicles service.

Description

technical field [0001] The present application relates to the field of communication, and in particular to a communication solution in the field of Internet of Vehicles, specifically including a communication architecture, method and device. Background technique [0002] V2X (Vehicle to Everything) refers to the communication system between vehicles, or between vehicles and pedestrians or cyclists, and between vehicles and infrastructure. The vehicle uses various sensors (such as lidar, millimeter-wave radar, etc.) and cameras on the vehicle to obtain vehicle driving conditions, system operating status (can be fed back through the CAN bus, such as brake status, turn signal status, etc.) and the surrounding road environment Information (the roadside system can broadcast static or dynamic information, and the vehicle can also have a built-in high-precision map, etc.), and at the same time obtain the accurate position information of the vehicle by means of GPS or other position...
