寻迹小车可以看作是缩小化的智能汽车,对智能汽车的研究有一定的借鉴意义.采用飞思卡尔公司的MC9S12DG128B作为核心控制芯片,设计了通过红外光电传惠器检测路径信息的智能寻迹小车.该系统由处理器模块、路径识别模块、电机驱动模块、舵机驱动模块、车速检测模块、液晶显示模块与电源模块等组成.实际应用表明,该小车可以在专门设计的跑道上快速平稳地实现寻迹功能.%The tracing car can be regarded as the contractible intelligent vehicle. Its research has a certain significance for the intelligent car. By using Freescale company's devices MC9S12DG128B as the core control chip, this paper designed the intelligent tracing car to detection route information through the infrared photoelectric sensor. The system includes processor module, path recognition module, motor driver module, servo driver module, speed detection module, LCD module,power supply module and so on. The practical application shows that the car can rapidly and smoothly realize the tracing function in the runway of the special design.
