Abstract

A first stroke sensor and a second stroke sensor in a braking control device detect the pedal depression amount. A brake ECU calculates a target wheel cylinder pressure by utilizing the detected pedal depression amount, and increases/decreases the wheel cylinder pressure by controlling the hydraulic actuator so as to achieve the calculated target wheel cylinder pressure. The brake ECU determines whether the brake pedal has been sharply depressed, by utilizing the pedal depression amount detected within a range thereof that is smaller than the pedal depression amount. If it is determined that the brake pedal has been sharply depressed, the brake ECU relaxes the restriction on the hydraulic pressure gradient at the time of increasing the wheel cylinder which is imposed when the brake pedal has not been sharply depressed.
