Development Of An Economy Car’s Body Control Modular

Along with the rising living standard of the people, the cars especially the economy cars began to enter the lives of ordinary people. Body control modular(BCM) as an part of the vehicle has important influence on the vehicle safety, comfort and convenience. In order to improve and promote domestic economic type of car body control system level, this paper analyzes and discusses the hardware structure of the system, selection of core components, the design of SCADE logic function code and CAN communication from the principle of the body control system. Based on this, the paper designs an economy car’s BCM with CAN bus. Now, this BCM has been already assembled in HUATAI B11experimental vehicle. The related experiences and tests have been completed. We come to the conclusion that the BCM designed in this paper meets the design requirements.Also, the wire harness is reduced effectively. Furthermore this design puts forward the improvement measures by using SCADE software in view of the current automotive electronics software design. Therefore, the project development time is shortened and the reliability and maintainability of the code is improved.According to the good performance, the distributed BCM based on CAN bus will be gradually applied in economy car. This type of BCM has the advantages of high reliability, real time communication, convenient connection and so on. It may have important significance in improving the domestic independent BCM research level. Keywords:BCM, CAN bus, Automotive electronic, Body control system...
