Abstract
A control method of a hydraulic pressure source-driven type vehicle hydraulic pressure brake system in which no irritating noises or vibrations are produced during stoppage of the vehicle and which does not consume electric power in waste. When the vehicle stops and the surroundings become quiet, by detecting stoppage of the vehicle by a sensor for detecting the rotation of a wheel, stopping a motor for a pump for producing brake hydraulic pressure, and opening a solenoid valve in a master cylinder passage bringing the master cylinder and the wheel cylinder into communication with each other, it is possible to prevent noises or vibrations from the motor and wasteful consumption of electric power.
