  "textContent": "A method of controlling a pump-driven type vehicle hydraulic brake system which can suppress pulsation of brake hydraulic pressure and makes it possible to accurately and quickly apply brake hydraulic pressure is provided. Using an equation between the pressure rising speed of the hydraulic pressure in the master cylinder (8) and the approximate required driving force of the motor (1), the driving force of the motor (1) is set from the pressure rising speed of the detected hydraulic pressure. The driving force of the motor (1) is controlled to minimize the hydraulic pressure difference between the brake hydraulic pressure increased by the preset driving force and the hydraulic pressure in the master cylinder (8), thereby bringing the brake hydraulic pressure substantially close to the hydraulic pressure in the master cylinder (8). Only for the remaining hydraulic pressure difference, the motor driving force is controlled with a small control output to quickly and precisely apply brake hydraulic pressure while suppressing pulsation of the brake hydraulic pressure.",
