Summary: | PROBLEM TO BE SOLVED: To generate car body deceleration expected by a driver, in the case of an increase step-in by the driver during pulse increase pressure control. SOLUTION: In an anti-skid control device, based on an output signal of a wheel speed sensor, controlling a hydraulic control valve so as to perform at least decrease pressure and pulse increase pressure in a brake fluid pressure of a wheel cylinder, a step-in amount of a brake pedal is detected, based on this detection signal, the step-in amount of the brake pedal is decided for whether it is increased or not. In the case of increasing the brake pedal step-in amount, duty ratio of pulse increase pressure control is changed so as to increase its increase pressure time ratio, based on the changed duty ratio, a brake hydraulic pressure of the wheel cylinder is controlled by pulse increase pressure. |
