The invention discloses an auxiliary emergency braking method and device for a rail transit vehicle. When the distance between an obstacle and a train is smaller than a braking safety distance when aconventional emergency braking system is adopted for braking at the current running speed, higher emergency braking pressure can be obtained through a newly added auxiliary emergency braking system, so that the braking safety distance of the train from the current running speed to the static state is shorter, the train is prevented from colliding with the obstacle, the probability of traffic accidents is reduced, and the running safety of the train is improved. According to the method, whether the auxiliary emergency braking system is started or not and which stage of braking pressure is started for the auxiliary emergency braking system are judged according to the distance between the obstacle and the train, unnecessary auxiliary emergency braking times and braking strength are reduced, and mechanical abrasion and train impact are reduced while traveling safety is guaranteed.

    本发明公开了一种轨道交通车辆辅助紧急制动方法及装置,当障碍物与列车之间的距离小于在当前运行速度下采用常规紧急制动系统制动时的制动安全距离时,通过新增的辅助紧急制动系统可以获得更大的紧急制动压力,使列车从当前运行速度到静止状态时的制动安全距离更短,避免了碰撞到障碍物,降低了交通事故发生的概率,提高了列车运行的安全性;该方法还根据障碍物与列车之间的距离判断是否启动辅助紧急制动系统以及启动辅助紧急制动系统哪一级制动压力,减少了不必要的辅助紧急制动次数和制动强度,在保障行车安全的同时减少了机械磨损和列车冲击。
