Analyzing the mechanical structure of car model, the thesis studies a conduct traffic control algorithm for the smart car and achieves a hardware system which consists of five parts: power circuit, track detecting system based on infrared, front-wheel steering device, motor driving device, and remote control circuits. The thesis develops a PID algorithm to control the drive motor and achieves a Fuzzy control algorithm to control the steering motor. As a result, the smart car can detect and follow the typical road of straight road, snake road and big radius road automatically. The experimental results show that the smart car can track the black-guide lane smoothly, and the average speed is over 1.3 meter per second on different type lanes.Key words:smart car lane detection ARM fuzzy control1引 言智能车是一个由传感器、控制机构和控制算法组成的智能系统,其基本原理为由道路识别模块猎取道路信息,经微处理器处理后产生舵机与后轮电机的驱动信号,使智能车沿着预设有黑色引导线的白色道路前进,实现自主导航。智能车的设计涉及计算机、电力电子、电机拖动等知识,其开发不仅有着诱人的应用领域和商业前景,而且是对人类智能化技术的挑战。智能车以 LPC2210 微控制器为核心,配有路径识别系统,前轮转向装置,电机驱动装置和...
