The invention relates to a railway vehicle air brake control unit, a brake control device and an emergency brake control method. The air brake control unit includes: a filling solenoid; an exhaust electromagnetic valve, wherein a pipeline is connected with the air outlet end of the filling solenoid; a switching valve, wherein the gas inlet end of the switching valve is connected with a distribution valve through a pipeline; an empty and load vehicle valve, wherein a second air inlet end pipeline of the empty and load vehicle valve is connected with an air outlet end of the switching valve; and a double pre-control relay valve, wherein the first pre-control pressure input end of the double pre-control relay valve is connected with the air outlet end of the empty and load valve through the pipeline, the second pre-control pressure input end of the double pre-control relay valve is connected with the connecting end of the filling solenoid and the exhaust electromagnetic valve through the pipeline, and the air outlet end of the double pre-control relay valve is connected with a brake cylinder. According to the application, the problem of accidental emergency braking caused by the fault of the emergency braking electromagnetic valve is solved, and the reliability of the braking control function is improved.
