Claim:
1. A vehicular brake controller including a motor, a pump configured to be driven by the motor to suck and discharge brake fluid, a plurality of wheel cylinders connected to a discharge end of the pump by way of control valves, and a hydraulic pressure control means configured to control a braking hydraulic pressure generated at each of the wheel cylinders by controlling the motor and the control valves, wherein the hydraulic pressure control means includes a target pressure acquiring means configured to acquire a target pressure being a target value of a hydraulic pressure applied to each of the wheel cylinders by vehicle brake control, and an actual pressure obtaining means configured to obtain an actual wheel-cylinder pressure actually generated at each of the wheel cylinders, and, when the motor starts being driven to pressurize the wheel cylinder of a low-pressure-side wheel having the actual wheel-cylinder pressure lower than the actual wheel-cylinder pressure of any other of the wheel cylinders in a same system, performs hydraulic pressure restoration control of continuously driving the motor until the actual wheel-cylinder pressure of a high-pressure-side wheel having the actual wheel-cylinder pressure higher than the actual wheel-cylinder pressure of any other of the wheel cylinders in the same system falls in a predetermined range relative to the target pressure of the wheel, and performs shift suppression control of stopping pressurization of the wheel cylinder of the low-pressure-side wheel and turning OFF the motor when a difference between the target pressure and the actual wheel-cylinder pressure of the low-pressure-side wheel is less than a predetermined value.
