Title:
ブレーキ制御装置
Document Type and Number:
Japanese Patent JP5456009
Kind Code:
B2
Abstract:
A brake control device includes a relay valve that generates a first drive pressure for driving a brake, from an air pressure generated by a first air supply source, based on an pilot pressure applied, and a double check valve that connects the relay valve and a second air supply source that generates a second drive pressure separate to the first air supply source, and that communicates the drive pressure which is generated in either the relay valve or the second air supply source, with the brake. The device also includes a variable load valve that outputs a first pressure according to a pressure of an air spring fitted on a vehicle side, a first solenoid valve group which generates the pilot pressure from the air pressure during service operation, and a second solenoid valve group which outputs, as the pilot pressure, a second pressure according to the first pressure output from the variable load valve during emergency operation.
