To provide a brake control device capable of enhancing reliability of an emergency brake.SOLUTION: A brake control device 2 comprises: a brake controller 20; a regular electromagnetic valve 21 which operates according to brake control by the brake controller 20; an emergency electromagnetic valve 22 which directly operates according to an emergency brake command; and a relay valve 25 which sets pressure of air input through the regular electromagnetic valve 21 or emergency electromagnetic valve 22 to a command pressure, and feeds air in pressure corresponding to the command pressure to a brake cylinder 3. The brake controller 20 detects input of an abnormal signal related to the emergency electromagnetic valve 22 when detecting input of the emergency brake command, and performs valve control in abnormality detection time to the regular electromagnetic valve 21 when detecting input of the abnormal signal.SELECTED DRAWING: Figure 2
【課題】非常用ブレーキの信頼性を高めることができるブレーキ制御装置を提供する。【解決手段】ブレーキ制御装置2は、ブレーキ制御器20と、ブレーキ制御器20によるブレーキ制御に従って動作する常用電磁弁21と、非常用ブレーキ指令に従って直接動作する非常用電磁弁22と、常用電磁弁21又は非常用電磁弁22を介して入力される空気の圧力を指令圧力とし、当該指令圧力に対応する圧力の空気をブレーキシリンダ3に送出する中継弁25と、を備えている。ブレーキ制御器20は、非常用ブレーキ指令の入力を検知した場合に、非常用電磁弁22に係る異常信号の入力を検知し、当該異常信号の入力を検知した場合に、常用電磁弁21に対し、異常検知時の弁制御を行う。【選択図】図2
