Abstract: A brake fluid pressure controller for a vehicle includes: wheel brakes; a master cylinder for supplying pressure to a brake fluid; at least one fluid pressure passage connecting the wheel brakes with the master cylinder; a pump provided on each fluid pressure passage for intensifying the brake fluid pressure; a revolution-controllable motor for driving the pump; a motor drive control part for controlling motor revolutions; a target fluid pressure calculation part for setting a target fluid pressure of the brake fluid; a brake fluid pressure acquisition part; and a fluid pressure deviation calculation part for calculating a difference between the target fluid pressure and the brake fluid pressure. When the difference is less than a predetermined value, the motor drive control part drives the motor at a smaller number of revolutions, as compared with a case where the difference is the predetermined value or more.
