Abstract:
Brake fluid pressure control apparatus includes: fluid pressure passage from a fluid pressure source to a wheel brake; pressure regulating valve arranged on the passage; pump for feeding pressurized brake fluid to the passage between the valve and the wheel brake; motor for driving the pump; and controller which controls an electric current applied to the valve in accordance with target fluid pressure for the wheel brake to control fluid pressure supplied to the wheel brake. The controller includes: means for converting the target fluid pressure into fluid volume and calculating required flow rate from this fluid volume; means for calculating required rotation speed of the motor from the required flow rate and on the basis of efficiency of the pump; and means for increasing the electric current applied to the valve for a predetermined value when the required rotation speed exceeds actual rotation speed of the motor.
