With the development of intelligent connected vehicles,the traditional vehicle communication system has been difficult to meet the increasing demand for data transmission.This paper proposes a design scheme of intelligent vehicle communication system based on vehicle Ethernet,which adopts layered architecture and integrates key technologies such as physical layer standard of vehicle Ethernet,audio and video bridging protocol and time sensitive network protocol.The research results show that the communication system based on vehicle Ethernet can effectively meet the requirements of intelligent vehicles for high bandwidth,low delay and real-time,which provides an important support for the development of intelligent networked vehicles.
