To meet the requirements of high bandwidth and high reliability brought by the continuous development of unmanned vehicle technology and increasingly complex vehicle-borne network,a hub(HUB)for vehicle network was designed.The time-triggered protocol(TTP)was adopted by the design,and the architecture of time-triggered Ethernet(TTE)and star topology TTP bus was designed.The data bandwidth was improved by TTE,and the bus type communication mode was replaced by the driven equipment in the physical layer by the point-to-point connection mode,and the reliability was improved.The bus type communication mode was disconnected at one point,and the problem of overall communication failure was solved.The design of HUB was described in detail,and the feasibility and reliability of the design were verified by experiments.It provides a feasible solution to the optimization of the vehicle network.
