Patent ID: 8457818

Claim:
A train slide control device comprising: a slide control unit configured to control an electromagnetic valve unit and a relay valve; the electromagnetic valve unit having a supply valve that supplies supplied compressed air, through the relay valve, to a brake cylinder and an exhaust valve that adjusts a pressure of the supplied compressed air; the relay valve is configured to output a pressure of the brake cylinder according to the compressed air supplied from the electromagnetic valve unit; and the slide control unit includes: a velocity-difference detecting unit configured to detect a velocity difference of each wheel of a train, based on a velocity signal; a deceleration calculating unit configured to calculate a deceleration of the train based on the velocity signal; a sliding-amount determining unit configured to determine a sliding-amount of each wheel of the train based on the velocity difference and deceleration; and a brake-cylinder-pressure calculating unit configured to calculate a pressure control signal for controlling a pressure of the brake cylinder based on: the sliding-amount; a brake command for obtaining a predetermined deceleration; and a signal that indicates the pressure of the compressed air and pressure of the brake cylinder.
