| There are diverse types of Electronic Control Units (ECUs), which coexit and are independent in most domestic cars, while information transmit and relevant control among each ECUs are very important for ensuring the safety and comfort of cars. By building Car Information Centralized Control System (CICCS) based on Controller Area Network (CAN), independent ECUs are connected, information sharing and relevant control are realized, which is one of trends of electronic technologies of cars. For CICCS, the implementation of its control functions is based on control rules. Whether control rules are right or not will influence correctness, reliability and validity of CICCS. At the same time, CICCS aims at incidents, so it is necessary to study relevant control rules of CICCS according to different incidents in the course of driving.Firstly, considering the situation that different ECUs are controlled separately, the author of this dissertation analyzes structure of CICCS based on CAN by studying characteristic of CAN and information transmit among different ECU. Secondly, according to the result of analyzing characteristics of CICCS and following the theory and structure of generating rule, control course of CICCS is built. Thirdly, the author analyzes the impact of various factors from highway codes and traffic conditions on driving safety of cars by studying impacts of the human-car-condition system on driving characteristics. Fourthly, according to conditions of city highways in domestic, the author studies braking characteristics of beeline, ramp and steering, and figures out the braking distance and the safety braking distance, on the basis of analysis of braking whole course as well. Finally, on the basis of CICCS based on CAN, the author analyzes driving characteristics and builds relevant control rules of CICCS as to the various given incidents in different driving conditions, taking the highway codes, traffic conditions, drivers and other factors into account.
