摘　　要：在能见度较低情况下，如何避免高速公路上汽车追尾是个急待解决的问题，提出了以单片机为核心的微机控制系统，利用超声波的特性来测量两车前后相对距离，介绍了超声波测距原理、系统的硬件和软件设计．很好地解决了汽车追尾问题．In visibility too weak, It is a problem flow to avoid back car from knocking down front one on highways. An microcomputer control system on single-chip processor is raised in this paper, to measure the car's relative distance in front or back by ultrasonic wave. The theory to measure distance by ultrasonic wave and design for system's hardware & software is introduced .The problem of preventing back car from knocking down front one is solved better.
