摘要
针对LIN总线数据帧传输异常的问题,利用示波器测定车辆LIN总线异常数据帧,试验分析了LIN总线对地加载、LIN总线对电源加载、LIN总线带不同电阻对地加载、LIN总线带不同电阻对电源加载和LIN总线断路的波形,利用测得的数据帧信号电平判断数据传输异常原因.结果表明,不同故障引起的LIN总线数据信号波有一定区别,传输异常的原因可通过波形分析来甄别.
Aiming at the problem of abnormal transmission of LIN bus data frame,using oscilloscope to measure the abnormal data frame of vehicle LIN bus,the paper analyzes the waveforms of LIN to ground load,LIN to power load,LIN with different resistance to ground load,LIN with different resistance to power load and LIN open circuit,and uses the measured data frame signal level to determine the cause of abnormal data transmission.The results show that there are some differences in LIN bus data waves caused by different faults,and the causes of abnormal transmission can be identified by waveform analysis.
