Abstract

There is provided an integrated electro-hydraulic brake system. The integrated electro-hydraulic brake system include a power source unit including an accumulator configured to store a pressure of a predetermined level, a pump configured to suck oil from a reservoir and discharge the oil to the accumulator in order to generate a pressure in the accumulator, and a motor configured to drive the pump; and an integrated hydraulic control device including a master cylinder having two hydraulic circuits and configured to generate a hydraulic pressure, a reservoir connected above the master cylinder and configured to store oil, an in-valve and an out-valve configured to control a pressure delivered from the accumulator to a wheel cylinder installed in each wheel, a shut off valve configured to control a fluid pressure delivered from the master cylinder to the wheel cylinder, a pedal simulator connected to the master cylinder and configured to provide a reaction force of a brake pedal, and a simulation valve installed in a rear end of the pedal simulator, wherein the power source unit is provided as a separate unit in order to isolate operating noises, and the integrated hydraulic control device and the power source unit are connected by an external pipe, and the out-valve is provided as a normally open type-solenoid valve that is used at low current ranges, normally maintains an open state in order to reduce heat generation, but is closed when a close signal is received, compared to a normally close type-solenoid valve that normally maintains a close state.

Description

[0001] This application claims priority from Korean Patent Application No. P2013-0155090 filed December 13, 2013, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to an electro-hydraulic braking system, and in particular, to an integrated electro-hydraulic braking system that provides an actuator including a master cylinder, a pedal simulator, etc., an electronic stability control (ESC), and as A hydraulic power unit (HPU) of a single unit. Background technique [0003] Recently, in order to improve fuel efficiency and reduce exhaust gas, hybrid vehicles, fuel cell vehicles, electric vehicles, etc. have been actively developed. A braking device, that is, the braking device of a vehicle braking system, must be installed in such vehicles. Here, the vehicle braking system refers to reducing the speed of a traveling vehicle or stopping the vehicle. [0004] A braking device of a common automobile braking system...
