Brake control device

摘要

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.

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 be supplied from the power fluid pressure source toward a wheel cylinder for each wheel; an isolation valve capable of isolating fluid communication into both a first channel through which the operating fluid from the manual fluid pressure source can be supplied to a wheel cylinder for the left front wheel and that for the right rear wheel, and a second channel through which the operating fluid from the manual fluid pressure source can be supplied to a wheel cylinder for the right front wheel and that for the left rear wheel; and a regulation unit positioned in a channel between the first channel and the second channel and configured to regulate, when the operating fluid having passed through the fluid volume control valve is supplied from the first channel and the second channel to each wheel cylinder, a state of supplying the operating fluid and reduce a difference between a state of supplying operating fluid to one of the first channel and the second channel by passing through the isolation valve, and a state of supplying the operating fluid to the other of the first channel and the second channel without passing through the isolation valve.
