摘　　要：介绍了一种基于红外传感器进行路径识别的智能寻迹赛车的设计与实现方案。赛车系统采用红外传感器检测赛道白线,通过舵机控制赛车转向,直流电机调节车速,使赛车能够实现快速稳定的寻迹行驶。详细阐述了系统中电源管理、路径识别、电机驱动、车速检测等重要环节的实现方法,并通过赛车运动模型的建立与分析,对赛车的方向控制和速度控制提出了较为理想的解决方案。A design and implementation of an intelligent-searching-track race car based on infrared sensor is introduced. The race car system, with infrared sensor to identify the white-guide-line in the middle of the road, uses servo to steer and drivers the race car with DC motor to make sure that the race car can track the white-guide-line automatically and move forward following the line rapidly and smoothly. Implementation methods of power management, path recognition, motor drive, speed control and many other important aspects are expounded. What＇ s more, after establishing and analyzing the geodynamic model of the race car, preferable control strategies for steering and speed are presented.
