预防汽车追尾系统设计

The design of avoiding the rear-end collision system

介绍了预防公路追尾碰撞报警系统,系统由信息采集单元、中央控制单元、报警电路和显示输出单元构成。信息采集单元由4种传感器完成对车辆运行状态信号的采集,中央控制单元对输入信息进行分析、处理,完成防碰撞预测与判断功能,报警电路产生警报,提醒驾驶员采取措施以避免追尾碰撞事故发生,系统还具备显示功能。

The article introduces the warming system when a traffic accident caused by Rear-end collision between two cars . The system includes the collecting informatiosplay unit etc. First, the car running states are collected by fn unit, the central controlling unit, the alarm circuit and the diour 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.
