摘　　要：本文根据先进的车身控制理念,采用现场总线技术和电子技术等研制了基于CAN总线的车门控制系统。提出了设计方案,设计了硬件电路,在μC/OS-II实时操作系统下编写了软件,制定了CAN总线编码协议;并且通过对车窗电机结构进行分析与测试获得了车窗夹持特征,提出了车窗“防夹”控制策略。实验证明该控制系统克服了传统汽车车门控制的弊端,能够达到现代化车身控制的需求。Based on advanced controlling thesis of car＇s body ,car＇s door controlling system based on CAN bus by using electronic technique is discussed in the paper, We gave out the schemes about this system.designed the hardware.programmed software based on μC/OS-Ⅱ RTOS and wrote CAN protocols, And analyzed direct current motor.obtained characteristic of blocked car＇s window. gave out tactic of avoiding block, By experiment, it was proved this system can overcome the defect of traditional control of car＇s body, and can satisfy the requirement of modernization control of car＇s body.
