跟着科技的日趋成长，人们对汽车的请求愈来愈高，在市场的赓续需要下，新型的多功效小汽车应用技巧愈来愈成熟，同时也推动着汽车智能化的成长。智能汽车与一样平常所说的主动驾驶有所不同，它指的是应用多种传感器和智能公路技巧实现的汽车主动驾驶，智能车辆能够辨认周围环境、主动断定、多功效驾驶等集成浩繁驾驶技巧的综合体系，它把计算机技巧、传感器技巧、信息技巧、通信技巧、智能机械辨认和主动化等技巧，应用了各类新型的技巧。今朝，智能车辆重要朝着平安、温馨，和供给精良的车人、人车互换体系。
本次计划的智能循迹小车重要以单片机89S52为节制焦点，实现主动循迹、避障和手机遥控。循迹电路采纳4路红外光电发射对管，并采纳L298作为机电的驱动芯片，并在四位数码管上表现及时门路，实现循迹功效。当不克不及循迹时，能够采纳手机长途结束遥控。当小车避障传感器检测到车的后方有障碍物时，会主动结束运转，并收回报警声。

ABSTRACT
Along with the increasingly growing science and technology, people are more and more requests for car high in Geng continued needs of the market, the new multi-functional car application skills more mature, but also to promote the growth of intelligent vehicles. Smart car as usual and said active driving different, it refers to the application of a variety of sensors and smart highway driving skills to realize vehicle active, intelligent vehicle can recognize the surrounding environment, the initiative concluded multi-functional integrated voluminous driving and other driving skills integrated system, which the computer skills, sensor techniques, information skills, communication skills, intelligence and other machinery to identify and automation techniques, the application of new types of skills. Currently, intelligent important vehicle towards peace, warmth, and well-supplied car people, vehicles exchange system.
Smart car tracking this important program to microcontroller 89S52 as focus control, proactive tracking, obstacle avoidance and remote control handset. Tracking circuit adopted four infrared emission tube, and adopt the L298 as electromechanical driver chips, and performance opportunities in a timely manner on four digital tube, to achieve tracking effect. When the tracking can not, it is possible to adopt the remote end of the phone call. When the car obstacle avoidance sensor detects the rear of the vehicle there is an obstacle, it will take the initiative to end the operation, and to recover the alarm sound.
