The Research And Application Of Vehicle Body CAN-bus Control System

Vehicle electronics is a complex, multilateral and synthetic high-tech which embodies micro & power electronics, mechanism and computer science. As a serial bus with high speed, high reliability, and low cost for distributed real time control applications, CAN (Controller Area Network) is a distinguished example of vehicle electronics.The thesis is a conclusion of two years' work in Automobile Bus Application Institution of HFUT. First, the basic topology and theory of the vehicle body control system based on the CAN-BUS is introduced. Secondly, the thesis analyses and discusses the issues of hardware configuration, parameter optimization, controlling methodology, and software implementing. Then, the CAN-BUS based vehicle body control system has been developed successfully. Every intelligent node in the system can exchange data with the network, at the same time, more functions of automatic detection and protecting are provided, and its flexible design also adapts to more applications. A vehicle body equipments control with intelligence and network is achieved.The thesis introduces a special software package------Component-OrientedMulti-Value Description Language. The package consists of detection, rule and execution expressions, which can solve the complicated logical control problem in the system. Embedded System, Embedded Operation System, host computer Interpreter program are also discussed.The thesis analyses the performance of the conceptual vehicle. Furthermore, according to the developing trend of the vehicle electronics, it proposes a new way of improvement and perfection of the transfer from concept to product.
