汽车舒适CAN总线系统故障诊断与研究

Fault Diagnosis and Research of the Automotive Comfortable CAN Bus System

随着CAN总线系统在汽车控制领域的广泛应用,CAN总线系统故障对汽车控制功能实现有很大的影响,以迈腾B7轿车舒适CAN总线为例,系统阐述舒适CAN总线在汽车领域的应用,并分析舒适CAN总线的标准波形;针对常见的舒适CAN总线的故障类型,重点分析各类常见故障对应的故障波形。通过分析CAN总线故障类型所对应的故障波形,可以极大提高CAN总线的故障诊断与排除效率。

With the applications of CAN bus system in the field of automotive control, the failure of the CAN bus system has a great influence on the realization of the auto control function. Take the Magotan B7 comfortable CAN bus as an example, this paper describes the application of the comfortable CAN bus in the field of automobile and analyzes the standard waveform of the comfortable CAN bus. In view of the fault types of common comfortable CAN bus, this paper focuses on the analysis of the fault waveforms corresponding to various common faults. The author believes that the fault diagnosis and removal efficiency of the CAN bus can be greatly improved by analyzing the fault waveform of the fault type of the CAN bus.
