The invention discloses a backward rear-end collision emergency avoidance method and system based on a visual technology, and the method comprises the steps: obtaining the real-time position information and real-time driving parameter information of a vehicle and other vehicles on a lane according to a data collection unit carried by the vehicle; according to the real-time position information and the real-time driving parameter information, the driving path of the vehicle is planned; and according to the planned driving path, enabling the vehicle to realize backward rear-end collision emergency avoidance. A visual identification technology is adopted, a lane where a rear vehicle is located is rapidly judged through a lane line and a vehicle position relation, and then whether a collision risk exists or not is judged through pre-collision time, and a strategy of emergent acceleration or lane changing avoidance of the vehicle is adopted. According to the method, the defects of false triggering of emergency lane changing caused by inaccurate millimeter-wave radar recognition and inaccurate judgment of the lane position of a rear vehicle are effectively overcome, the surrounding environment of the vehicle is detected in real time through the whole-vehicle vision technology, and when the rear-end collision risk exists, the collision risk of the vehicle is reduced through the strategy of emergency acceleration or lane changing avoidance.

    本发明公开了一种基于视觉技术的后向追尾紧急避让方法及系统包括,根据自车携带的数据采集单元,获取自车与车道上其他车辆的实时位置信息以及实时行驶参数信息;根据实时位置信息以及实时行驶参数信息,对自车行驶路径进行规划;根据规划后的行驶路径,使得自车实现后向追尾紧急避让。采用视觉识别技术,通过车道线和车辆位置关系快速判断后车所在车道,进而通过预碰撞时间判断是否存碰撞风险,自车紧急加速或变道避让的策略。有效弥补毫米波雷达识别,对后方车辆车道位置判断不准,导致误触发紧急变道的缺陷利用全车视觉技术对车辆周围环境实时检测,当有后方追尾风险时,自车通过紧急加速或变道避让的策略,降低碰撞风险。
