摘　　要：针对车辆追尾在道路交通事故中所占比重较大,分析车辆追尾事故发生的原因,运用道路交通流的跟驰理论,构建车辆防追尾数学模型,研究预防车辆追尾的有效方案。采用传感器、单片机、显示屏等构建硬件电路,运用C语言编程实现距离探测、制动控制等既定功能。采用模型车验证法对装置的功能进行检验,结果表明该装置具有优良的工作性能。Rear-end collision coutrols a large proportion of road traffic accidents.Causes of rear-end accidents were analyzed, mathematical models for such accidents were built with car-following theory of road traffic engineering, effective approach for avoiding rear-end collision was studied. Hardware circuits were designed with sensors, single chip, display screen and so on. Certain functions were realized via C language, such as distance measurement, braking control. Model cars were employed to test the performances of this device. Results show that the working performance of the device is good.
