預(yù)防汽車追尾系統(tǒng)設(shè)計(jì)

介紹了預(yù)防公路追尾碰撞報(bào)警系統(tǒng)，系統(tǒng)由信息采集單元、中央控制單元、報(bào)警電路和顯示輸出單元構(gòu)成。信息采集單元由4 種傳感器完成對車輛運(yùn)行狀態(tài)信號(hào)的采集，中央控制單元對輸入信息進(jìn)行分析、處理，完成防碰撞預(yù)測與判斷功能，報(bào)警電路產(chǎn)生警報(bào)，提醒駕駛員采取措施以避免追尾碰撞事故發(fā)生，系統(tǒng)還具備顯示功能。

Abstract：The article introduces the warming system when a traffic accident caused by
Rear-end collision between two cars . The system includes the collecting information
unit , the central controlling unit, the alarm circuit and the display unit etc. First, the
car running states are collected by four sensors, Then, All of the collecting
information is analyzed and judged by a single chip microcomputer, forecasting and
judging will be complicated, If there is a hidden trouble of rear-end collision
accident, an alarm will be given ,In addition, display unit is designed.
Key words：sensor collecting information rear-end collision alarming system
