Title:
RAILROAD CAR BRAKE CONTROL DEVICE AND RAILROAD CAR BRAKE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/123556
Kind Code:
A1
Abstract:
This railroad car brake control device comprises: a brake control unit (11) that outputs a control signal designating a brake pressure on the basis of a brake command; and an output unit that adjusts the pressure of fluid to be supplied from a fluid source according to the brake pressure and outputs the pressure-adjusted fluid. In the brake control unit (11), a required braking force calculation unit (22) calculates a required braking force which is a braking force required to obtain the deceleration designated by the brake command. A temperature calculation unit (24) calculates the temperature of a friction material of a mechanical brake device. A friction coefficient calculation unit (25) calculates the coefficient of friction of the contact surface between the friction material of the mechanical brake device and a rotating body. A brake pressure calculation unit (26) calculates the brake pressure from the required braking force and the coefficient of friction.
