TL;DR: In this article, the authors present a vehicle motion control system, which includes wheel brake cylinders, an automatic hydraulic pressure generating apparatus for generating a hydraulic braking pressure irrespective of operation of a brake pedal, a hydraulic pressure control valve device disposed between the pressure generator and the wheel cylinders, and a controller for controlling the controller and the valve device in response to conditions of vehicle motion.

TL;DR: In this article, a vehicle motion control system for maintaining vehicle stability by controlling the braking force applied to at least one of the front and rear wheels of a vehicle is presented, on the basis of a condition of the vehicle in motion and irrespective of depression of a brake pedal.

TL;DR: In this article, a brake force distribution control system comprising wheel speed sensing is presented, where S1, S3 which detect wheel speeds 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 M2 calculating a difference between the standard wheel speeds VWSFR, VWSRR, respectively, and driving means M3 operating a pressure control valve unit FV depending on the differences so as to modulate brake force

TL;DR: In this article, a wheel brake pressure controlling system is described, which includes a microcomputer for estimating a turning of a vehicle, determining if a turning is in a over- or under-steer region, and for determining a wheel braking, the pressure of which is to be intensified if the turning of the vehicle lies in an over-or under-stretch region.

TL;DR: In this article, a feedback control portion is provided to produce feedback control pulse signals indicative of a difference between a target slip ratio and an actual slip ratio, and a feed forward control portion was provided to successively convert the target slip ratios in relation to a required braking force, a hydraulic braking pressure and an amount of hydraulic braking fluid, in sequence, and to convert the amount of braking fluid into a feedforward control pulse signal, regardless of the extent to which a brake pedal of the vehicle is depressed.
