摘　　要：针对车身控制器的发展现状以及未来发展趋势进行分析,提出了一种基于ARM-MCU和Linux操作系统的集中式车身控制器内部通信的设计思路;同时对车身控制器中主控制器和子节点间的通信协议、ARM和MCU之间的通信接口以及触摸屏中的操作界面程序进行了研究,在ARM9和16位MCU的联合工作的基础上,嵌入Linux操作系统,实现整个车身网络的集中、有效、快捷的控制。The current status and the future development trend of the body control modules are analyzed by this paper,and a new design idea of Intercommunication for the centralized body control module based on the ARM--MCU and the Linux operation system is presented.Also the communication protocols between the main controller and the sub--nodes,the communication interfaces between ARM and MCU,and the operation interfaces on the touch screen are researched.Based on the teamwork of the ARM9 and the 16 bits MCU,the Linux OS is embedded to make the control of body network much more centralized,efficient and faster.
