摘 要
随着科技的日益发展,人们对汽车的要求越来越高,在市场的不断需求下,新型的多功能小汽车应用技术越来越成熟,同时也推动着汽车智能化的发展。智能汽车与一般所说的自动驾驶有所不同,它指的是利用多种传感器和智能公路技术实现的汽车自动驾驶,智能车辆可以识别周围环境、自动判断、多功能驾驶等集成众多驾驶技术的综合系统,它把计算机技术、传感器技术、信息技术、通讯技术、智能机器识别以及自动化等技术,应用了各种新型的技术。目前,智能车辆主要朝着安全、舒适,和提供优良的车人、人车交换系统。
本次设计的智能循迹小车主要以单片机89S52为控制核心,实现自动循迹、避障以及手机遥控。循迹电路采用4路红外光电发射对管,并采用L298作为电机的驱动芯片,并在四位数码管上显示实时路径,完成循迹功能。当不能循迹时,可以采用手机远程进行遥控。当小车避障传感器检测到车的前方有障碍物时,会自动停止运行,并发出报警声。

ABSTRACT
Along with the development of science and technology, people on the car demand is higher and higher, in the market continued demand, the new type of multi-function car application technology is more and more mature, but also promote the development of intelligent, the car. Smart cars and general had said to be automatic driving different, it refers to the use of sensor and intelligent road technology of the realization of the automatic car driving, intelligent vehicle is a collection of environment planning and decision-making, perception, different functions such as auxiliary driving in an integrated system, it focuses on the computer, using modern sensor, information fusion, communication, artificial intelligence and automatic control technology, is typical of high-tech complex.
At present the studies of intelligent vehicle is mainly devoted to improve the cars safety, comfort, and provide good car interface.This design intelligent tracing the car on main on the single chip computer 89 S52 as control core, with 4 road electrcal to launch tube, and by using the L298 as the motor drive chip, and in the four digital tube display real-time path, complete the following mark function.
Keywords: tracking car, 89S52,L298,Motor drive
