The invention discloses a rail transit vehicle emergency braking method and system, the system comprises a first braking system and a second braking system, when the rail transit vehicle needs to arrive at a station, the first braking system is started, and when the front of the rail transit vehicle encounters an obstacle, the distance X between the rail transit vehicle and the obstacle is measured through a distance measuring system; when the distance X is larger than or equal to the first braking safety distance, the first braking system is started, when the distance X is smaller than the first braking safety distance and larger than or equal to the second braking safety distance, the second braking system is started, and when the distance X is smaller than the second braking safety distance, the first braking system and the second braking system are started. And an anti-collision system is started, so that damage is reduced.

    本发明公开了轨道交通车辆的紧急制动方法及系统,本发明包括第一制动系统和第二制动系统,当轨道交通车辆要到站时,启动第一制动系统,当轨道交通车辆的前方遇到障碍物时,通过测距系统,测量处轨道交通车与障碍物间的距离X,当距离X大于或等于第一制动安全制动距离时,启动第一制动系统,当距离X小于第一制动安全制动距离,且大于或等于第二制动安全距离时,启动第二制动系统,当距离X小于第二制动安全距离时,启动第一制动系统和第二制动系统,并开启防碰撞系统,减少损伤。
