The Design of Automobile Electric Control System Based on CAN BUS

随着汽车技术的飞速发展，汽车电子化程度越来越高，传统点对点通信方式已经不能适应汽车电子设备控制和数据通信的要求，汽车总线技术已经势在必行。如何在汽车上建立作为总线技术基础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。而目前利用CAN总线完成汽车综合控制系统中大量控制信号实时交换的技术，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。西门子公司已经利用PLC完成CAN总线控制系统，但其成本高，很多国内大型客车厂不能接受。本文的目的就是借鉴计算机网络和现场总线控制技术，将信息技术运用到汽车上，用实时、全面、有效的信息流来驱动汽车系统的运动，以...Along with the fast development of automobile technology, the electronical degree of automobile is more and more high. The traditional point to point corresponding mode has not already adapted to the automobile electronics equipments control and data correspondence. The bus technology is necessary certainly. How to build automobile electric control system based on bus technology is subj...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：20032901
