摘要
为了使汽车在倒车时能够有效的避开障碍物,详细介绍了一种基于STC90C51单片机的超声波测距的汽车倒车避障系统,利用发射超声波与反射回波的时间差来测量距离并用该距离模拟汽车倒车时车尾与障碍物之间的距离,若距离太近会进行语音和蜂鸣器预警,经过实际验证,验证了这一系统的正确性,将其应用于汽车倒车时,会使汽车有效的避开障碍物,达到安全驾驶。
In order to make the car can avoid obstacles effectively in reverse,this paper introduces a kind of vehicle reversing obstacle avoidance system based on STC90C51 microcontroller ultrasonic distance measurement system in detail.The system could measure distance with the time between transmit wave and reflected wave,and we can use this distance to represent the distance between the trail and the obstacle.If the distance is too close to the voice and buzzer warning,after the actual verification,verify the correctness of the system,when it is applied to reverse the car,the car will be effective to avoid obstacles,to achieve safe driving.
