Abstract

Official abstract text for this publication.

A brake control system has a manual fluid pressure source and a power fluid pressure source. A fluid pressure actuator forms an X-pipe having a first channel and a second channel. The power fluid pressure source supplies the operating fluid to each wheel by using the first channel and the second channel. A channel system including the first channel and a channel system including the second channel can be isolated from each other by an isolation valve. The fluid pressure actuator includes a regulation unit configured to regulate a state of supplying the operating fluid such that a difference between a state occurring when the operating fluid is supplied to one of the first channel and the second channel after passing through the isolation valve, and a state occurring when the operating fluid is supplied to the other channel without passing through the isolation valve, is reduced.

First claim

Opening claim text (preview).

The invention claimed is: 1. A brake control system comprising: a manual fluid pressure source configured to increase the pressure of a contained operating fluid in accordance with an amount of a brake operation by a driver; a power fluid pressure source in which pressure accumulation by the operating fluid is possible with the use of power independent of a brake operation by a driver; a fluid volume control valve configured to control a fluid volume of the operating fluid to…
