Distribution system for selectively controlling and supplying brake pressure to wheels
First Claim
1. An apparatus for controlling wheel brake pressures in a plurality of wheels comprisingbrake pressure generating means (2,5) operated by a driver for generating a pressure which responds to a magnitude of operation by the driver;
- a source of constant pressure (21,
22) for producing a substantially constant high pressure;
selection means (64, 65, 61-63) for each wheel for selecting one of the pressure corresponding to the magnitude of operation and the high pressure produced by the source;
first intensifying/reducing means (312) for selectively supplying either pressure, selected by the selection means, or a low pressure to a front right wheel brake (51);
second intensifying/reducing means (334) for selectively supplying either pressure, selected by the selection means, or a low pressure to a front left wheel brake (52);
third intensifying/reducing means (356) for selectively supplying either pressure, selected by the selection means, or a low pressure to a rear right wheel brake (53);
and fourth intensifying/reducing means (378) for selectively supplying either pressure, selected by the selection means, or a low pressure to a rear left wheel brake (54).

Abstract
A brake force distribution control system comprising wheel speed sensing means S1, S3 which detect wheel speeds VWFR, VWRR of a front right wheel FR and a rear right wheel RR respectively, standard speed calculating means M1 calculating first speed value B and second speed value C from each of the wheel speeds VWFR, VWRR, and figuring out front medium value of VWFR, B and C and rear medium value of VWFR, B and C as standard wheel speeds VWSFR, VWSRR respectively, comparison means M2 calculating a difference between the standard wheel speeds VWSRR and VWSFR and driving means M3 operating a pressure control valve unit FV depending on the differences so as to modulate brake force of the rear right wheel RR relative to that of the front right wheel FR.
