Abstract
In brake control based on commands of a plurality of systems, an adjustment valve adjusts fluid supplied from a fluid source to a predetermined pressure to output the pressure-adjusted fluid. An output valve switches opening and closing based on a switching command. A skid detector detects whether a car is skidding or not and notifies a brake controller. The brake controller determines a pressure of fluid output by a control valve and issues a command to solenoid valves provided in the control valve. The brake controller issues a command to a discharge valve to discharge fluid from the discharge valve when a skid is detected. A relay valve adjusts pressure of fluid from the fluid source based on a higher pressure between a pressure of fluid output by the output valve and a pressure of fluid output by the control valve, to output the pressure-adjusted air to a brake cylinder.
