The invention provides an automatic braking control system and method and an urban rail train. The system comprises a brake control device and a brake release train line which are arranged corresponding to a bogie of a train; each brake control device comprises a brake non-release state normally open node, a forced release electromagnetic piston valve and an electronic control unit; one end of the brake non-release state normally-open node is connected with the positive electrode of the brake release train line, and the other end of the brake non-release state normally-open node is connected with the forced release electromagnetic piston valve in the brake control device; and the electronic control unit is used for controlling the normally-open node in the braking control device in the non-relieving state to be closed after detecting the braking non-relieving fault, so that the forced relieving electromagnetic piston valve in the braking control device is electrified to execute the braking relieving action. According to the method, the self-repairing of the braking non-relieving fault can be realized, so that the main track fault processing time is shortened, the train delay or delay caused by the braking non-relieving fault is reduced, and the train operation efficiency and the operation service quality are improved.

    本发明提供一种自动制动控制系统、方法及城轨列车。该系统包括:与列车的转向架对应设置的制动控制装置和制动缓解列车线;每个制动控制装置包括制动不缓解状态常开节点、强迫缓解电磁活塞阀和电子控制单元;制动不缓解状态常开节点,一端与制动缓解列车线正极连接,另一端与本制动控制装置中的强迫缓解电磁活塞阀连接;电子控制单元,用于在检测到制动不缓解故障后,控制本制动控制装置中的制动不缓解状态常开节点闭合,以使本制动控制装置中的强迫缓解电磁活塞阀得电执行制动缓解动作。本发明能够实现制动不缓解故障的自修复,进而缩短正线故障处理时间,减少因制动不缓解故障造成的列车晚点或延误,提高列车运行效率及运行服务质量。
