摘要
随着软件在汽车领域的占比越来越高,车载软件的通信及刷新速率低的问题逐渐突出.文章介绍了ISO 13400 DoIP协议和ISO 14229诊断协议,分析DoIP帧格式和通信原理,设计刷新过程和诊断通信流程,实现了基于DoIP协议的诊断刷新功能,极大提高了ECU刷新的时间性能和效率.
Abstract
With the increasing proportion of software in the automotive field,the problem of low communication and refresh rate of in-vehicle software has gradually become prominent.This paper introduces the ISO 13400 DoIP protocol and ISO 14229 diagnostic protocol,analyzes the DoIP frame format and communication principle,designs the refresh process and diagnostic communication process,and implements the diagnostic refresh function based on the DoIP protocol,which greatly improves the time performance and efficiency of ECU reprogramming.
