Claim:
1. A vehicular brake control device comprising: a hydraulic pressure brake mechanism provided at each wheel of a vehicle and configured to generate braking force in accordance with a brake hydraulic pressure; a hydraulic pressure control means including a pump and a motor configured to drive the pump, and configured to drive the motor, operate the pump, and control the brake hydraulic pressure generated at the hydraulic pressure brake mechanism to an appropriate hydraulic pressure; and a hydraulic pressure setting means configured to set a target pressure as a target of control by the hydraulic pressure control means, for the brake hydraulic pressure generated at the hydraulic pressure brake mechanism; wherein the hydraulic pressure control means has 1) a regular control state for controlling increase of the brake hydraulic pressure with regular pressurization performance, and 2) an inhibited control state with pressurization performance lower than the pressurization performance in the regular control state, to increase the brake hydraulic pressure, the hydraulic pressure setting means includes a hydraulic-pressure-increase filter configured to regulate increase of the target pressure in accordance with an increasing change of the target pressure, and a hydraulic-pressure-decrease filter configured to regulate decrease of the target pressure in accordance with a decreasing change of the target pressure, and performs, in the inhibited control state, filter regulation processing of setting an effect of inhibiting the change of the target pressure by the hydraulic-pressure-increase filter to be lower than an effect of inhibiting the change of the target pressure by the hydraulic-pressure-decrease filter, the inhibited control state is brought for traction control of inhibiting acceleration slip of the wheel, and the hydraulic pressure setting means performs the filter regulation processing in the inhibited control state to increase, in comparison to the regular control state, a difference between the effect of inhibiting the change of the target pressure by the hydraulic-pressure-increase filter and the effect of inhibiting the change of the target pressure by the hydraulic-pressure-decrease filter.
