A hydraulic block of an electronic braking device for a vehicle includes a first input port and a second input port configured to receive a brake fluid from a main braking system, at least one oil chamber connected to one input port of the first input port and the second input port, a first output port and a second output port configured to discharge the brake fluid to a plurality of wheel brake apparatuses, a first inlet line configured to connect the first input port and the first output port to each other, and a second inlet line configured to connect the second input port and the second output port to each other, a first outlet line bifurcated from the first inlet line, a second outlet line bifurcated from the second inlet line, and a valve mounting unit mounted with a plurality of valves.

An integrated braking device for a vehicle equipped with wheel brakes includes a reservoir, master cylinder, bi-directional pumps each using hydraulic pressure oil from the reservoir for generating hydraulic pressure in first direction to apply braking force to the wheel brakes or generating hydraulic pressure in opposing second direction to control the hydraulic pressure oil from flowing to the reservoir, a hydraulic motor for driving the bi-directional pumps, inlet valves for controlling a hydraulic pressure from flowing from the bi-directional pumps to the wheel brakes, traction control valves each disposed between the master cylinder and each bi-directional pump to control flow of the hydraulic pressure oil inside the master cylinder, and a braking control unit for braking the vehicle by transmitting a driving signal to solenoid valves in the integrated braking device, the bi-directional pumps, and the hydraulic motor to control a flow of the hydraulic pressure.

A vehicle braking calibration system and related method includes a valve fluidly coupled with a vehicle braking system of a vehicle. The valve is configured to move between an open position and a closed position to control an amount of a fluid that is directed out of the braking system. A sensor detects one or more characteristics of the fluid that is directed out of the braking system. A controller determines a state of the braking system based on the one or more characteristics of the fluid.

A 3-way solenoid valve and a brake system for vehicle including same. The 3-way solenoid valve includes a valve chamber, valve block, a first operation assembly, a valve seat, and a second operation assembly.

A valve assembly with a valve body, which has a fluid passage designed as a fluid inlet and at least one fluid passage designed as a fluid outlet, is disclosed. A fluid chamber connecting the fluid inlet to the at least one fluid outlet is formed in the valve body. A movably mounted closing body is positioned in the fluid chamber. The closing body is guided axially and/or radially by at least one guide ball. The at least one guide ball is arranged between the closing body and a lateral delimitation of the fluid chamber. A fluid passage is formed in the radial direction of the valve body.

A brake driving apparatus includes a hydraulic valve block including a vent channel for discharging air to the outside, an electronic control device that includes an electrical component housing open in a direction of the vent channel of the hydraulic valve block and having a ventilation hole connected to an internal space and a filter attached to the electrical component housing to block the ventilation hole so that air can pass therethrough, and is supported by one side of the hydraulic valve block, and a vent sealing member that seals a space between the hydraulic valve block and the electronic control device and surrounds the vent channel, the ventilation hole, and the filter.

A brake system for motor vehicles may include an actuation device (e.g., brake pedal), a travel simulator to generate a feedback force on the actuation device, a first piston-cylinder unit having at least one piston that separates two working chambers that are connected via at least one hydraulic line to at least one wheel brake of a brake circuit, a control device and a pressure supply unit driven by an electric motor. At least one wheel brake may be assigned to each brake circuit, and each wheel brake may be connected to its associated hydraulic connecting line via a controllable switching valve. An outlet valve may be assigned to a single wheel brake or to a single wheel brake of each brake circuit in a hydraulic connection between the wheel brake and a pressure medium storage container, without any further valve disposed as such.

A pneumatic ABS valve device for a pneumatic brake system of a vehicle comprises a check valve mechanism for enabling a supply air flow from a supply port to a delivery port and blocking an air flow in the reverse direction. The check valve mechanism comprises a quick release insert disposed in an insert chamber, the quick release insert being placeable in a basic position for providing a chamber passage in the insert chamber enabling the supply air flow. The quick release insert is displaceable by an air pressure difference from the basic position into an activated blocking position, in which the chamber passage is at least diminished with respect to its basic position, in order to block an air flow from the supply port to the delivery port and enabling exhaust air flow.

[Problem] The present invention relates to a hydraulic control unit that includes a pump for increasing a hydraulic pressure of a brake fluid.

[Means for Resolution] The hydraulic control unit according to the present invention includes: a discharge channel from which the brake fluid is discharged, the brake fluid being pressurized by the pump; a pulsation reducing unit disposed in the middle of the discharge channel; and a controller controlling the pump and the pulsation reducing unit. The pulsation reducing unit includes: a valve housing; a fixed core fixed to the valve housing; a movable core received in the valve housing in an axially movable manner; a closing member interlocking with the movable core and closing the discharge channel; a coil disposed in a manner to surround the valve housing and the fixed core; and an inflow chamber which is formed by the valve housing and one end surface of the movable core, into which the brake fluid from the discharge channel flows, and whose volume can vary.
