摘要
控制器局域网总线技术(CAN)在轿车的应用越来越广泛,CAN总线通讯故障会导致轿车不能行驶、动力不足、舒适功能不能正常工作等故障。介绍了轿车CAN系统基本组成、控制原理以及CAN总线通讯故障的诊断方法,列举了两个CAN总线通讯故障实例来阐述其故障诊断过程,并总结了轿车CAN系统故障诊断要点,以提高轿车故障的诊断效率。
The application of controller area network-BUS(CAN)technology in cars is becoming more and more extensive.The communication failure of CAN bus will lead to the failure of the car,such as power failure,insufficient power failure and failure of the comfort function.The basic composition of the car CAN system,the control principle and the diagnosis method of CAN bus communication fault were introduced.Two CAN bus communication fault examples were enumerated to illustrate the fault diagnosis process,and the fault diagnosis key points of the car CAN system was summarized to improve the fault diagnosis efficiency of the car.
