Abstract:
A vehicular brake control apparatus comprising:brakes that apply braking forces corresponding to a pressure of a supplied operating fluid to wheels; a pump that force-feeds the operating fluid; a valve that adjusts the pressure of the operating fluid that is force-fed from the pump; and a controller that performs an operation control of the pump and the valve to control the pressure of the operating fluid to be supplied to the brakes when the controller determines that the braking forces are to be applied to the vehicle, wherein the controller controls a pressure-increasing gradient of a fluid pressure by controlling both the pump and the valve during a pressure-increasing control for increasing the pressure in the brakes, and wherein the controller controls the pressure-increasing gradient of the fluid pressure by performing a duty-driving operation of the pump with a duty ratio varying with time and a duty-driving operation of the opening and closing of the valve during the pressure-increasing control.
