The invention provides an emergency braking end-changing keeping control method which comprises the following steps: when a train changes the end, a cab of a head train is in an activated state, a signal system sends an end-changing signal, an LCU device of the head train outputs a high-level signal to drive two emergency braking relays of the train to be electrified, and meanwhile, a single-core control train line drives two emergency braking relays of a tail train to be electrified; after the end changing signal lasts for a set time, the signal system sends a tail car cab activation signal, and after emergency braking relays of the head car and the tail car continuously keep a power-on state for 500 ms or more than 500 ms, the signal system cancels the end changing signal and the head car cab activation signal, only the tail car cab is activated, and the tail car cab is activated; the LCU device of the tail train outputs a high-level signal to drive two emergency braking relays of the train to be powered on, and meanwhile, the train line is controlled by a single core to drive two emergency braking relays of the head train to be powered on; and end changing is completed. According to the invention, emergency braking caused by activation interruption of the cab in the automatic end changing process of the vehicle can be avoided, and the running safety of the vehicle is improved.

    本发明提供一种紧急制动换端保持控制方法,列车换端时,头车司机室处于激活状态,信号系统发送换端信号,头车LCU装置输出高电平信号驱动本车两个紧急制动继电器得电,同时通过单芯控制列车线驱动尾车两个紧急制动继电器得电;换端信号持续设定时间后,信号系统发送尾车司机室激活信号,头车和尾车的紧急制动继电器持续保持得电状态500ms或大于500ms后,信号系统取消换端信号和头车司机室激活信号,仅尾车司机室激活,尾车LCU装置输出高电平信号驱动本车两个紧急制动继电器得电,同时通过单芯控制列车线驱动头车两个紧急制动继电器得电;换端完成。本发明可保证车辆在自动换端过程中不因司机室激活中断而施加紧急制动,提高车辆的运行安全。
