利用飞思卡尔公司的MC9S12XS128单片机,以模型汽车作为平台,通过自动识别道路中心位置处由通有交变电流的导线所产生的电磁场道路检测,设计制作一种能实现自动寻迹的智能车的控制系统。在设计中,通过对道路中心导线磁场对传感器的作用建立模型,采用逐次逼近的方法实现智能车转弯控制,降低对模型精确度的要求,更好的满足智能车的容错能力。
Using Freescale’s MC9S12XS128 single-chip microcomputer to model the car as a platform, through the automatic identification of the center of the road by the exchange of current through the wires generated by the electromagnetic field road detection, the design of a smart car to achieve automatic tracking Control System. In the design, by establishing the model of the sensor’s role in the magnetic field of the road center and using the successive approximation to realize the turning control of the smart car, the requirements of the model are reduced, and the fault tolerance of the smart car is better satisfied.
