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 communicates, maintains, and reduces the brake fluid pressure supplied to the device, and a brake that is discharged from the wheel brake device when the brake fluid pressure is lowered by the pressure reduction operation of the fluid pressure control valve. For brake slip control, the main elements are a reservoir for each hydraulic piping system that stores fluid, and a hydraulic pump that pressurizes the brake fluid in the reservoir for each hydraulic piping system and supplies it to the upstream side of the hydraulic pressure control valve. In a vehicle hydraulic braking system equipped with an actuator, a switching control valve is installed in each hydraulic piping of the diagonal two-system system to communicate and cut off fluid in the hydraulic piping, and a brake is installed in a master cylinder. Two return pipes that individually communicate the master cylinder side reservoir that supplies fluid to the wheel brake devices of the driven wheels belonging to each hydraulic piping system, and each hydraulic pipe that is interposed between the two return pipes. An actuator for drive slip control consists of two switching valves that are operated by the hydraulic pressure applied to the valve, shut off the return piping when the hydraulic pressure is applied, and connect the return piping when the hydraulic pressure is not applied. When the idle state of the driving wheels is detected, the switching control valve is set to the cutoff side, the hydraulic pressure control valve installed in the hydraulic piping to the driven wheels is set to the pressure reducing side, and the hydraulic piping to the driving wheels is switched to the pressure reducing side. A hydraulic braking device for a vehicle, characterized in that a control unit is provided with control logic for switching a hydraulic control valve interposed therein to a communication side.
