Abstract

The invention provides an Internet of Vehicles communication solution. The solution is based on a framework or concept of a V2X central server (V2X Center, V2X-C) alliance, V2X-C nodes in multiple areas form the V2X-C alliance according to planning or self-organization, and the V2X-C nodes in the alliance exchange respective responsible V2X service area information. When the vehicle needs to obtain the Internet of Vehicles service firstly, the vehicle is connected to an affiliated V2X-C node; then, the V2X-C node judges whether the current vehicle is in a V2X service area covered by the V2X-Caccording to the position of the current vehicle; if so, a V2X region service node of a region where the vehicle is located is allocated to the vehicle according to the geological location of vehicle,and the access address of the V2X area service node is sent to the vehicle; and if not, other V2X-C nodes are requested to allocate V2X area service nodes according to the geographic location of thevehicle, and access information of the V2X area service nodes is transmitted to the vehicle, so that the vehicle can access the V2X server of the current area to 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...

Examples

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...
