The research of automobile electric control bus technology based on CAN/LIN mixed protocol

Abstract

传统汽车电气控制系统中采用的点对点通信方式,对于电子化程度越来越高的汽车而言,将使其线束十分复杂,不仅增加了电气系统成本,而且会因为节点繁多使系统运行可靠性降低。总线网络能够大量减少控制线数,提高可靠性,因此,采用总线控制成为汽车电气控制系统技术发展的必然趋势。如何在汽车上建立基于总线技术的汽车电气控制系统问题自然成为汽车电子领域广受关注的研究热点。西门子公司已经利用PLC完成CAN总线控制系统,由于其具有抗干扰性强、线路简化、传输速率高、系统可任意扩展等优点,正受到国内外高度重视,但其成本高,很多国内汽车生产厂家不能接受。在这种情形下,福州源光亚明电器有限公司(沈阳中顺汽车供应商)委托厦门大...The traditional automobile electrical control system used in peer-to-peer communications, the freetly increased electronic level of automobiel makes the wiring harness more complicated by which not only increases costs, but also lower the reliability of system because of the various nodes. Bus network can decrease the number of the control lines and increase the reliability greatly. Therefore, the...学位:工学硕士院系专业:物理与机电工程学院机电工程系_测试计量技术及仪器学号:2005130175
