Braking hydraulic pressure controller

Abstract

Abstract PURPOSE:To make braking force distribution approximate to an ideal, by setting desired braking hydraulic pressure according to the relative displacement between springing and unspringing of a car, while operating a solenoid valve, controlling confined pressure, with inlet hydraulic pressure and the said desired braking hydraulic pressure. CONSTITUTION:A hydraulic pressure setting device 75 of a microcomputer 73 outputs a desired braking hydraulic pressure signal Sc upon operation by means of a relative displacement signal Sp of springing and unspringing of a car out of a displacement detecting device 71. A comparing device 77 closes a solenoid valve 21 when inlet hydraulic pressure Pm becomes larger than the desired braking hydraulic pressure, As a result, with confined pressure in an enclosure chamber 51, set load of a spring 63 is thus set to a proper value.
