摘　　要：文中介绍了以MSP430F149为控制器,以NRF2401为无线收发芯片的汽车自动限速系统。该系统能根据道路状况、天气、车型三种参数综合设定限速值,行车进入不同的路段,自动地改变限速值,司机无法更改。通过检测当前车速,并与限速值进行比较,当超速30S时,发出超速语言报警提示,并控制汽车油路,使车速保持在限速值附近,从而达到自动限制汽车行驶速度的目的。这将大大减少交通事故的发生。The paper introduces the car automated speed limit system based on MSP430F149 controller and NRF2401 wireless receive and dispatch chips. The system can set up aggregate speed limit number through the three kinds of parameters in road state, weather and car model. When entering different sections, the cars can automatically change speed limit number, but the drivers cannot do it. The system tests the present speed and compares it with speed limit number. When cars exceed the speed limit for 30S, the system sends out speeding language alarm prompt, controls automobile oil line, and keeps the speed near the speed limit number to automatically limit running speed of automobiles. All of these measures will greatly reduce traffic accidents.
