With the progress of society and the development of science and technology, increasing the functional requirements of the society on the city bus. A large number of electronic control units (ECU: Electronic Control Unit) on the city bus, good to meet passenger demand for comfort, safety and economy of city bus, but also to meet government environmental protection for the city bus exhaust emissions requirements. Currently, various electronic control unit on a city bus in China to use more point-to-point connection, separate in the same car, the separation of control between the transmission of information and communication is not smooth, leading to the repeated use of the sensor and Harness complex. In order to improve the performance of the vehicle, on the city bus between each ECU integrated control and monitor the status of their work, a combination of their information and data information sharing between different ECU, judgment and reasoning unified control and status information to the urgent need to address the problem. Firstly, according to the characteristics of the city bus, city bus information integrated control system architecture, through the analysis of the type of system information, system information classification method, from the screening of public information, information extraction process and information processing method system information extraction methods; Second, CAN (Controller Area Network) bus protocol and application layer protocol based on CAN SAE J1939-based, asked the city bus information integrated control system description method. City bus information integrated control system for the object, based on the SAE J1939 protocol is designed for the needs of designers of the system bus, city bus information packets to query the database. Finally, the paper design city bus lamp control simulation system based on CAN bus. Before and after the design lights (Wai), a hardware configuration of the node, the switch control module to the computer simulation system, the switch control module via the software design to achieve the control of the various lights. Experimental results show that the proposed city bus information integrated control system description method is feasible, switch control module software designed to control individual lights. The basic work of this research work for the city bus information integrated control system has some theoretical significance and practical significance significant city bus network, intelligent.
