摘　　要：在循迹车控制系统中,使用红外发射和接收传感器进行有色路径的识别,以单片机为核心器件逻辑判断传感信号,并用驱动电路来控制车上的两个直流电机实现直行或转弯。驱动程序采用差速控制方式,通过中断产生不同的占空比信号,根据转弯方向设置控制参数,使两个电机转速不同,进而达到循迹车转弯平稳。In this paper, infrared emission and receiving sensor are applied for the identification of colored path in tracking ear control system. Besides, single chip is employed as the core component to judge sensing signal through using drive circuit to control two DC motors on the car to achieve going straight or turning comer. Regarding driver, mode of differential control is adopted. Different duty cycle signals are generated through thus making the speed of two interruption and control parameters are set based on turning direction, motors different. As a result, tracking car can be turned smoothly
