Internet of vehicles information system oriented to V2X network connection vehicles

Abstract

The invention discloses an Internet of vehicles information system oriented to V2X network connection vehicles. The system comprises a vehicle terminal T-BOX, a mobile APP client side and a server background system; one mobile phone APP is bound with one vehicle terminal T-BOX; the vehicle terminal T-BOX is mounted on the vehicle through an OBD interface, the vehicle terminal T-BOX on each vehiclecan perform ad-hoc networking with the other vehicles in a communication range and perform communication through a V2X(802.11p) dedicated short-distance wireless communication mode; and the vehicle terminal T-BOX communicates with the server background system through a 4G / 5G wireless mode. The Internet of vehicles information system provided by the invention is formed by combination with demandsof the present vehicle networking and vehicle security pre-warning and the disadvantages of the current single-vehicle communication.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, and is an information system for the Internet of Vehicles based on V2X to realize mutual wireless communication between automobiles through an ad hoc network. Background technique [0002] With the rapid development of mobile Internet information technology and services, consumers' demand for car interconnection and intelligent transportation is increasingly strong. More and more cars have installed T-BOX (Telematics BOX, on-board communication controller), on the one hand, it can connect cars to the Internet, and calculate the optimal vehicle shunting strategy through the server to relieve traffic pressure, and at the same time enable passengers to enjoy network resources , to bring a better user experience; on the other hand, by replacing some of the functions of the car's central control system, it can relieve part of the processing pressure of the car's central control system...

AI Technical Summary

Problems solved by technology

[0006] (1) Vehicle-mounted monitoring and service systems mostly serve to provide road condition information, guidance information, network services, and monitor vehicle driving routes to driving vehicles. During this process, driving vehicles only passively receive remote service information. Possible dangers cannot be predicted and warned in real time, and the system's contribution to the driving safety of the vehicle is not obvious

[0007] (2) The existing vehicle-mounted terminal system is limited to the risk avoidance within the range of self-vehicle perception, and there is a problem of "information islands" when vehicles are driving. There is a lack of information interaction between vehicles and vehicles, and between vehicles and roadsides. This situation of mutual isolation The effect and effect of the existing system on suppressing traffic accidents are not ideal

[0008] In addition, due to the important use value of vehicle mobile positioning for driving safety, the outdoor positioning technology based on GPS is widely used in vehicle positioning technology at present, but GPS signals are easily interfered and blocked by obstacles. In environments such as tunnels, tunnels, and indoors, the positioning error is relatively large, and the accuracy is difficult to meet the actual requirements.
