Brake control device for railway vehicles

Abstract

This brake control device (1) for a railway vehicle controls a mechanical brake device that obtains a brake force by pressing a friction material against a rotating body that rotates when the railway vehicle travels, the brake control device comprising: an output target value calculation unit (12) that calculates a minute output target value, which is a target value of a minute pressing force of the friction material in response to a proximity control signal, which is a control signal to bring the friction material in proximity to the rotating body without generating a deceleration force in the railway vehicle; and a correction control unit (13) that receives input of the proximity control signal and, on the basis of a target deceleration, which is a deceleration set as a target for the railway vehicle, and an actual deceleration, which is the actual deceleration of the railway vehicle acquired by a deceleration acquisition means, makes a correction of reducing the minute output target value when the actual deceleration is higher than the target deceleration, and outputs the corrected minute output target value to the mechanical brake device.
