摘要
根据先进的车身控制理念,研制了基于CAN总线的车门控制系统。提出了基于P89C51系列单片机的系统方案,设计了硬件电路,在μC/OS-Ⅱ实时操作系统下编写了软件,并且通过对车窗电机运行特点进行分析与测试获得了车窗夹持特征,提出了基于积分算法的车窗"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并能达到预期的控制效果。
This paper discussed a car door controlling system based on advanced controlling thesis of car＇s body and CAN bus .It out the schemes based on P89C51, designed the hardware, programmed software based on μC/OS-Ⅱ RTOS, and analyzed direct current motor, obtained characteristic of blocked car＇s window, gave out solution of integral arithmetic to avoid block .By experiment, it was proved that this system can overcome the defect of traditional control of car＇s body and can reach the anticipant purpose.
