摘 要: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。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。 关键词:自动避障;单片机; 避障电路;超声波测距
Abstract: With the development of automobile industry in our country, the automobiles’safety and intelligence become more and more important. The emergency lane-change maneuvers of vehicles may be handled through 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 introduced 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. Key words: drive automatically; single-chip microcontroller; the obstacle avoidance circuit; supersonic distance- measuring |
