途观车载网络系统的检修
摘 要：介绍了途观车载网络CAN总线技术在汽车上的应用，以及CAN总线出现的故障及检测和维修方法，就像汽车电子技术在20世纪70年代引入集成电路、80年代引入微处理器一样，现在数据CAN总线技术的引入也将是汽车电子技术发展的一个里程碑。随着电子、程控技术、集成电路及单片机在汽车上的应用，汽车的大多数部件控制由传统的机械控制逐步转变为现在的电子、程控控制，如电控燃油喷射发动机、自动变速器、电子转向和防盗系统等的控制。技术的进步，控制精度的提高，这就使得汽车上的控制单元数目增加，控制单元数目增加后导致线束增多、电路复杂、质量大、成本高、故障多、维修困难，为了减少线束、减少成本、优化结构，必须采用一种线束少、信息传输快、可控性强的信息传递系统。因而，一种新型的信息传递技术CAN总线技术产生了。

Repair in vehicle network system the Tiguan
Abstract: This paper introduces the application of the Tiguan vehicle network of CAN bus technology in the automobile, and the CAN bus faults and detect and repair methods, like the automobile electronic technology into the integrated circuit, in twentieth Century 70's 80's introduced the microprocessor, now the introduction of data of CAN bus technology will also be a milepost development of automotive electronics technology. With the application of the integrated circuit and single chip microcomputer, electronic, programmable control technology in automobile, most parts of the car is controlled by the mechanical control of traditional gradually into the present electronic, programmable control, such as the control of electronic control fuel injection engine, automatic transmission, electronic steering and anti-theft system etc.. The progress of technology, the control precision is improved, which makes the number of control unit on vehicles increase, the control unit causes increased, increasing the number of the wire harness circuit complexity, quality, high cost, failure, repair is difficult, to reduce the wiring harness, reduce cost, optimize the structure, we must adopt a harness, information transmission speed, strong controllability of the information transmission system. Therefore, a kind of new information transmission technology of CAN bus technology has produced.

总结
CAN总线作为一种可靠的汽车计算机网络总线，现已开始在先进的汽车上得到应用，从而使得各汽车计算机控制单元能够通过CAN总线共享所有的信息和资源，以达到简化布线、减少传感器数量、避免控制功能重复、提高系统可靠性和可维护性、降低成本、更好地匹配和协调各个控制系统之目的，随着汽车电子技术的发展，具有高度灵活性、简单的扩展性、优良的抗干扰性和纠错能力的CAN总线通信协议必将在汽车电控系统中得到更广泛的应用。
