汽车CAN总线研究分析与干扰防范

Channel Analysis and Precaution of Interferences Exist in CAN-BUS

通过对CAN总线特性和总线信道的分析,并利用汽车CAN电子控制系统的实际情况探究了汽车CAN总线的干扰问题并且提出了实践证明可行的防干扰措施;同时探讨了CAN总线传输信息的速率、信道容量和节点容量等关键技术问题。

This paper analyzes and describes the characteristic and signal channel of CAN-BUS, researches into the origin of interference problem, and advances many useful measures against interference which are testified in a bus system based on CAN-BUS, and explains how the data transmits on CAN-BUS with the process of light signal communication, then discusses the CAN-BUS key technical problems as the transmission speed, channel capacity, node capacity and so on, also discusses the key problems on development of CAN-BUS and expects the future trend of CAN-BUS according to the Chinese circumstances of research on the CAN-BUS in the end of this paper.
