The invention discloses a vehicle emergency obstacle avoidance control method and system, and the method comprises the steps: judging whether there is an obstacle in front of a vehicle or whether the speed of a vehicle behind the vehicle exceeds a set threshold value or not according to the surrounding environment information of the vehicle; if the obstacle exists in front of the vehicle, first pre-collision time of the vehicle and the obstacle is calculated according to the driving state data of the vehicle and the speed and distance of the obstacle in front of the vehicle; whether the first pre-collision time is larger than a set threshold value or not is judged, if yes, it is indicated that no collision risk exists, and if not, it is indicated that the collision risk exists; if the speed of the vehicle behind the own vehicle exceeds the set threshold value, second pre-collision time of the own vehicle and the vehicle behind the own vehicle is calculated according to the driving state data of the own vehicle and the speed and the distance of the vehicle behind the own vehicle, and if the second pre-collision time is smaller than the set threshold value, a brake lamp is controlled to be turned on so as to remind the vehicle behind the own vehicle to keep a safe vehicle distance. And the driver of the vehicle is reminded of rear-end collision risk.

    本发明公开了一种车辆紧急避障控制方法及系统,方法包括根据车辆周边环境信息,判断车辆前方是否存在障碍物,或,自车车辆的后车车辆速度是否超过设定阈值;如果车辆前方存在障碍物,则根据自车车辆的行驶状态数据、前方障碍物的速度和距离,计算自车车辆与障碍物的第一预碰撞时间;判断所述第一预碰撞时间是否大于设定阈值,如果是,则表示不存在碰撞风险,如果否,则表示存在碰撞风险;如果自车车辆的后车车辆速度超过设定阈值,则根据自车车辆的行驶状态数据、后方车辆的速度和距离,计算自车车辆与后方车辆的第二预碰撞时间,如果所述第二预碰撞时间小于设定阈值,则控制刹车灯点亮,以提醒后车保持安全车距,提醒自车驾驶员有追尾风险。
