とを特徴とする車両用液圧ブレーキ制御装置。 A control unit is located in a connecting pipe connecting a master cylinder and a wheel brake device of a drive wheel, and receives a command from a control unit that evaluates control slip and/or drive slip of the drive wheel to brake the wheel brake device of the drive wheel. a hydraulic pressure control valve that controls hydraulic pressure; and a reservoir that stores brake fluid discharged from the wheel brake device via the hydraulic pressure control valve when the brake hydraulic pressure is reduced by the control of the hydraulic pressure control valve; pressurizing the brake fluid in the reservoir;
a first hydraulic pump that can be supplied to a main pipe connecting the master cylinder and the hydraulic pressure control valve; , a first valve device that normally communicates in both directions and blocks fluid communication from at least the discharge side of the hydraulic pump to the master cylinder side by the discharge pressure of the hydraulic pump;
a bypass pipe that bypasses the hydraulic pressure control valve and the first valve device in the connecting pipe and connects the wheel brake device and the master cylinder;
Normally, a second valve device that communicates with the brake fluid and shuts off during drive slip control is provided, and the reservoir is composed of a first reservoir that stores brake fluid in advance and a second reservoir that can store brake fluid. A second hydraulic pump whose discharge side is directed toward the suction side of the first hydraulic pump is provided in the conduit connecting the reservoir, and the second hydraulic pump is connected in series with the second valve device to the master cylinder side. A hydraulic brake control device for a vehicle, characterized in that it is provided with a check valve whose forward direction is .
