摘　　要：当前中高端车型的配置越来越高,控制单元的数量也随之增多,总线使用的数量增加,那么总线系统出现的故障概率也会增加。目前,解决总线系统故障是维修企业的难点之一。本文以实车测量的数据和波形为依据,分析了通过测量总线终端电阻和总线波形来进行总线系统故障判断及对应维修故障的方法。At present, the configuration of middle and high-end vehicles is getting higher and higher, and the number of control units is increasing accordingly. The probability of bus system failure would increase while the number of buses increase. The solving of bus system failures is one of the difficulties of maintenance enterprises. Based on the measured data and waveform of real vehicle, this article analyzes the method of fault diagnosis and maintenance of bus system by measuring terminal resistance and waveform of bus.
