The invention discloses an expressway automobile rear-end collision prevention system and a working method thereof. According to the system, a non-contact radio frequency identification mode based onRFID is adopted to realize vehicle positioning and vehicle speed identification, and early warning of vehicle tailgating is realized, so that the problem of failure of rear-end collision early warningwhen encountering curve obstacles in a rear-end collision prevention system based on laser and radar technologies is solved, the problem of poor real-time performance of rear-end collision early warning in the rear-end collision prevention system based on an image recognition technology is solved, and the problem that lanes cannot be distinguished in the rear-end collision prevention system basedon a global positioning technology is solved. The system is simple in structure; the position of a vehicle Cj is obtained by reading RFID non-contact radio frequency identification electronic tags placed at equal intervals PL on the center line of the traffic lane; and the system has 100% acquisition accuracy and shortest position acquisition time, is not influenced by weather factors and curve obstacles, and ensures the real-time performance of early warning of the vehicle rear-end collision prevention system.
本发明公开了一种高速公路汽车防追尾系统及其工作方法，该系统采用基于RFID非接触式射频识别的方式实现车辆定位和车速识别，预警车辆追尾，解决了基于激光、雷达技术实现的防追尾系统中遭遇弯道障碍物追尾预警失效的问题，解决了基于图像识别技术实现的防追尾系统中追尾预警实时性差的问题，解决了基于全球定位技术实现的防追尾系统中无法区分车道的问题。本发明系统结构简单，读取等间隔PL放置在行车道中心线的RFID非接触式射频识别电子标签的方式获得车辆Cj位置的方式，具有100%的获取正确率和最短的位置获得时间，不受天气因素影响、弯道障碍物影响，保证了防车辆追尾系统预警的实时性。
