Patent ID: 7568773

Claim:
A brake fluid pressure controller for a vehicle for controlling brake fluid pressures of a plurality of wheel brakes to respective target fluid pressures comprising: the plurality of wheel brakes; a fluid pressure-supply part configured to supply pressure to a brake fluid; at least one fluid pressure passage connecting the plurality of wheel brakes with the fluid pressure-supply part; a pump which is provided on each fluid pressure passage and capable of intensifying the brake fluid pressure; a revolution-controllable motor configured to drive the pump; a motor drive control part configured to control a revolution number of the motor; which further comprises: a target fluid pressure calculation part configured to set a target fluid pressure of the brake fluid for each of the wheels; a brake fluid pressure acquisition part configured to acquire a brake fluid pressure for each of the wheels; and a fluid pressure deviation calculation part configured to calculate a difference between the target fluid pressure set by the target fluid pressure calculation part and the brake fluid pressure acquired by the brake fluid pressure acquisition part; the motor drive control part driving the motor at a smaller number of revolutions in a case where a difference at the wheel brake between the target fluid pressure and the brake fluid pressure is less than a predetermined value, as compared with a case where the difference between the target fluid pressure and the brake fluid pressure is the predetermined value or more.
