Abstract
A braking pressure control apparatus for a braking system having brake cylinders including a pressurizing device capable of pressurizing a working fluid and controlling a pressure of the pressurized fluid, a plurality of pressure control valve devices each of which is disposed between the pressurizing device and at least one of the brake cylinders and is operable to control flows of the fluid between the pressurizing device and the corresponding at least one brake cylinder, for thereby regulating the fluid pressure in the corresponding at least one brake cylinder, and a pressurizing-device control device operable to control the pressurizing device for controlling an output pressure of the pressurizing device on the basis of an operating state of each of the pressure control valve devices, which operating state determines the state of fluid flow between the pressurizing device and the corresponding at least one brake cylinder.
