基于51单片机的小车避障电路实现

The Achievement of the Vehicle Avoiding Obstacle's Circuit Based on Microcontroller 51

随着汽车工业的发展,汽车本身的安全性和智能性日益得到重视。目前,国内外已经有了很多有关汽车自适应驾驶的理论和实验。汽车的紧急避障是由计算机模拟驾驶员的主动控制过程,以汽车为控制对象进行实时信号采集、分析和处理,在紧急情况下可代替驾驶员的驾驶操作。现介绍模型小车自适应行驶和避障的一个实例,通过超声波传感器感知车辆行驶环境,实现小车的自适应巡航、避障等功能。

Inpace with development of the automobile industry in our country, the automobiles＇ safety and intelligence become more and more important. Nowadays, the methods and experiments of auto drive have been studied in domestic and international. The emergency lane-change maneuvers of vehicles may be handled throgh a process of disposing message by computer automatically,as good as a driver. It takes the vehicles as the carrier to control objects and deal with the message at real time. When emergency situation appears, it replaces the driver to avoid manual mistakes. The text introduces a case of a model car avoiding the obstacle itself. The model can perceive the information of the front road by the wave so as to cruise and evade the obstacle.
