Vehicle-mounted network communication system

Abstract

A vehicle-mounted network communication system, the system includes: a vehicle-mounted unit, a roadside communication unit and a wireless MESH network, and the vehicle-mounted units, and the vehicle-mounted unit and the roadside communication unit are connected through the wireless MESH network. The above solution can improve the data transmission speed and flexibility of the vehicle communication network and reduce the cost.

Description

technical field [0001] The invention belongs to the technical field of road safety, in particular to a vehicle network communication system. Background technique [0002] With the continuous enrichment of people's material life, cars have increasingly entered thousands of households. While cars are convenient for residents' lives, they also bring potential safety hazards. The number of cars in China is growing rapidly, and road traffic accidents occur frequently. [0003] In order to reduce the occurrence of traffic accidents, active safety technology based on vehicle communication has emerged as the times require, which can be used to prevent and reduce vehicle accidents and avoid personal injury. It has become a new way of thinking that countries are currently trying to solve road traffic safety problems. The active safety technology based on vehicle communication, through the communication between vehicles, can enable the vehicle to predict the driving intention of near...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, communication between vehicles, and between vehicles and roadside communication units is carried out through a specific short-range communication (Dedicated Short Range Communication, DSRC) network, but this communication method has the disadvantages of low data transmission speed, The problem of poor flexibility and high cost
