【摘要】 随着人们生活水平日益提高,轿车尤其是经济型轿车开始进入平常百姓的生活中。车身控制系统作为汽车上重要部件之一,对汽车的安全性、舒适性、便捷性有重要的影响。为了提高和促进国产经济型轿车车身控制系统的水平,本文从车身控制系统基本原理出发,对系统的硬件构成,核心元器件的选择,底层驱动,SCADE逻辑功能代码设计,CAN通讯设计进行了分析与讨论。在此基础上,设计了带CAN总线的经济型轿车车身控制系统。目前这套系统已经安装在华泰B11的实验车上,进行了相关的调试和实验工作。满足了当初的设计要求,并且减少了车身内的线束。同时针对当前汽车电子的软件设计提出了改进,将SCADE应用于汽车电子实际工程之中,缩短了项目的开发时间,降低了开发成本,并且提高了代码的可靠性与可维护性。实验和实际工作经验表明,基于CAN总线的车身控制系统将会逐渐的应用于经济型轿车之中。此类车身控制系统具有可靠性高、通信实时性好、连接方便等显著优点,对进一步提高国产自主轿车车身控制系统理论研究具有重要意义。更多还原

【Abstract】 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更多还原
