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. A valve is provided for each of the hydraulic piping systems and is interposed between each reservoir and the master cylinder side reservoir and is actuated by the braking fluid pressure applied to the wheel brake device for each of the hydraulic piping systems. A drive consisting of a switching valve that communicates the reservoir for each hydraulic piping system and the reservoir on the master cylinder side when the hydraulic piping system cannot be used, and shuts off between the reservoir for the hydraulic piping system and the master cylinder side reservoir when braking hydraulic pressure is applied. In a hydraulic braking device having a slip control actuator, the hydraulic pressure supplied from the hydraulic pump for each hydraulic piping system during drive slip control is stored for each hydraulic piping system, and the hydraulic pressure is stored for the next drive slip control. A hydraulic braking device for a vehicle, characterized in that it is provided with an accumulator that supplies hydraulic pressure to wheel brake devices belonging to each hydraulic piping system.
