The present invention relates to a hydraulic block for redundancy of an electronic braking device for a vehicle. The hydraulic block for redundancy includes: a block body part; a hydraulic control port formed on the block body part, and connected with a first output line of a main braking device, and a first hydraulic braking line for hydraulic braking of one of front and rear wheels; a drain port formed on the block body part, and connected with a second output line of the main braking device, and a second hydraulic braking line for hydraulic braking of the other one of the front and rear wheels; and a hydraulic circuit part forming a fluid flow path in the block body part, housing a valve mounted on an electronic controller, and controlling a flowrate and pressure of fluids passing through the hydraulic control port and the drain port such that, in a redundancy situation, one of the front and rear wheels performs hydraulic braking through the hydraulic control port, and the other one of the front and rear wheels performs motor braking through the drain port. Therefore, the present invention is capable of miniaturizing and lightening a hydraulic block, thus reducing material costs.

    본 발명은 차량용 전자제동장치의 리던던시용 유압블럭에 관한 것으로, 블럭본체부와, 블럭본체부 상에 형성되고, 메인제동장치의 제1아웃풋라인, 전륜과 후륜 중 일측의 유압제동을 위한 제1유압제동라인과 연결되는 유압제어포트와, 블럭본체부 상에 형성되고, 메인제동장치의 제2아웃풋라인, 전륜과 후륜 중 타측의 유압제동을 위한 제2유압제동라인과 연결되는 드레인포트와, 블럭본체부의 내부에 유체의 유로를 형성하고, 전자제어장치에 장착된 밸브가 수용되며, 리던던시 상황에서 전륜과 후륜 중 일측은 유압제어포트를 통해 유압제동을 수행하고, 전륜과 후륜 중 타측은 드레인포트를 통해 모터제동을 수행가능하게 유압제어포트와 드레인포트를 통과하는 유체의 유량과 압력을 조절하는 유압회로부를 포함하는 것을 특징으로 한다.
