汽车高速CAN线缆的传输特性研究

Research on the Transmission Characteristics of In-Vehicle High-Speed CAN Wires

目前对于汽车高速控制器局域网(CAN)线缆的传输特性认识存在一些问题,未能很好地解释高速CAN的某些工作特性与故障现象.通过对高速CAN的工作环境与结构分析,建立了高速CAN线缆的传输模型,进行了相关计算验证,并应用新模型解释了高速CAN线路系统的故障现象.

At present there are some problems in the understanding of the transmission features of in-vehicle high speed CAN lines whose working features and faults are not well explained. This paper establishes a transmission model of high-speed CAN based on an analysis of its working environment and structure, conducts related calculation verification and explains the faults with the new model.
