摘　　要：随着时代的进步,汽车ECU的软件层级越来越丰富,软件功能越来约完善,软件定义汽车时代已经来临,随着大容量,高频次的车辆软件刷写的需求越来越频繁,在试制/工厂端,区别于售后,整车OTA功能尚未启用,需要一种OTA,更加便捷的、更加高效的远程刷写方式。本文通过汽车总线DoIP 协议进行介绍,结合当今最先进的5G网络通信技术,VXLAN技术打通无线诊断数据传输通道,实现多车辆,多ECU的软件群刷,并重点阐述如何实现5G终端之间一对的多车辆有序刷写,并对远程诊断数据传输过程中安全问题做了简单的论述。With the progress of The Times,the software level of automobile ECU is becoming more and more rich,and the software functions are becoming more and more perfect.The era of software-defined automobile has come.With the demand for high-capacity and high-frequency vehicle software brushing more and more frequently,the OTA function of the vehicle has not been enabled in the trial production/factory end,which is different from the after-sales end.More convenient,more efficient remote brush way.In this paper,the automobile bus DoIP protocol is introduced,combined with the most advanced 5G network communication technology,VXLAN technology can get through the wireless diagnostic data transmission channel,realize the software group brush of multiple vehicles and multiple ECUs,and focus on how to realize the orderly brush of multiple vehicles between 5G terminals.The security of remote diagnostic data transmission is briefly discussed.
