基于普通示波器的车载CAN总线传输信号的测试分析

Test and Analysis of Transmission Signal in Vehicle CAN Bus Based on Universal Oscilloscope

介绍用普通数字示波器测试汽车车载网络CAN总线传输信息的方法;比较分析典型传输信号波形图,为车身舒适系统CAN总线的正常与故障运行状态下的判断提供参考。

The authors introduce the test method of signal transmission in vehicle CAN bus by using universal oscilloscope. Via comparing typical transmission signal’s waveform,they provide a reference for judgment of CAN bus in good or failing status in vehicle body system.
