けたことを特徴とする車両用液圧式制動装置。 The wheel brakes for each wheel are controlled by the signal from the control unit, which is installed in the diagonal two-system hydraulic piping from the master cylinder to the wheel brake device for each wheel, and generates a signal based on the wheel speed signal from the wheel speed sensor. A hydraulic pressure control valve that individually controls the brake fluid pressure supplied to the device, and a hydraulic piping system that stores the brake fluid discharged from the wheel brake device when the brake fluid pressure is lowered by the operation of the hydraulic pressure control valve. a brake slip control actuator whose main elements include a reservoir, and a hydraulic pump that pressurizes brake fluid in a reservoir separate from the hydraulic piping system and supplies it to the upstream side of the hydraulic pressure control valve; A control unit is installed in each hydraulic piping of the system system, and detects and evaluates the wheel slip situation based on the signal from the wheel speed sensor installed on the wheel, and issues a signal.The control unit uses the signal from the master cylinder and the brake slip control unit. Switching control that isolates the actuator from the hydraulic pressure control valve and communicates the upstream side of the hydraulic pressure control valve with the master cylinder side reservoir via a pressure control valve that opens when the hydraulic pressure exceeds a predetermined value. The valve is interposed between one of the reservoirs provided for each of the hydraulic piping systems and the master cylinder side reservoir, and is actuated by braking hydraulic pressure applied to the wheel brake device of the hydraulic piping system. A driving slip comprising a switching valve that communicates between the one reservoir and the master cylinder side reservoir when the brake fluid pressure is not applied, and shuts off between the one reservoir and the master cylinder side reservoir when the brake fluid pressure is applied. In a hydraulic braking system having a control actuator, the hydraulic pressure supplied from the hydraulic pump for each hydraulic piping system during drive slip control is stored together, and the stored hydraulic pressure is applied to the wheel brake system during the next drive slip control. A hydraulic braking device for a vehicle, characterized in that it is provided with an accumulator that supplies water to the vehicle.
