Document Type and Number:
Japanese Patent JP2696518
Kind Code:
B2
Abstract:
A method of controlling a hydraulic braking pressure for a vehicle wherein a reference deceleration is set corresponding to an amount of braking operation, a standard hydraulic braking pressure is determined corresponding to the reference deceleration and an amount of electricity corresponding to the standard hydraulic braking pressure is applied to an actuator so as to allow the hydraulic braking pressure to be fed to a braking unit in dependence on the amount of electricity applied thereto so that ideal control for the hydraulic braking pressure is performed in correspondence to the quantity of braking operation. An apparatus for controlling a hydraulic braking pressure for a vehicle wherein its structure is simplified so as to carry out the aforementioned method. The apparatus is so constructed that a spool adapted to change over a communicated state between output port, input port and release port in dependence on an axial displacement thereof is slidably fitted in a housing having input ports leading to the hydraulic pressure sypply source, output ports leading to braking units and release port leading to an oil tank, an actuator adapted to generate a thrust force in dependence on an amount of electricity input thereinto is operatively connected to one ends of the spools and a hydraulic pressure chamber leading to the output port is formed in the housing to generate hydraulic force adapted to counteract against a thrust force while it is exposed to the other end face of the spool.
