摘　　要：CAN总线是一种串行数据通信总线,主要用于车载设备之间的通信。CAN总线是一种无主总线,在通信过程中每个节点均可以作为主机进行发送,作为从机进行接收,各个节点发送数据时采用仲裁机制进行发送,保证了数据发送的有序性,但是同时也容易受到外界干扰而发生错误。列举了CAN总线错误的状态、CAN总线错误的种类以及触发机制,对CAN总线错误基于Verilog代码进行分析,并通过ISIM仿真对CAN总线各种错误的触发机制进行了研究,分析了CAN总线错误产生的原因。CAN bus is a kind of serial data communication bus,used in communication between devices on cars.The state of CAN bus errors,the variety of CAN bus errors,and the mechanism of CAN bus error triggering are all given in this paper.The states of CAN bus errors,the types of CAN bus errors,and the mechanism of CAN bus error triggering are discussed.The can bus errors are discussed based on Verilog-HDL code,and are researched with ISIM simulation,and the reasons of CAN error are discussed in this paper.
