Disclosed are a brake apparatus for a vehicle and a control method thereof. According to one embodiment of the present invention, the control method of the brake apparatus for a vehicle comprising a reservoir for storing working fluid, a master cylinder connected to the reservoir, a wheel brake configured to receive hydraulic pressure from the master cylinder, a residual pressure control hydraulic line communicating with the reservoir and the wheel brake, a control valve installed on the residual pressure control hydraulic line, an input unit for generating the required braking pressure required for the wheel brake, and a controller for controlling the degree of opening of the control valve comprises the steps in which: the controller determines the pressure difference between the required braking pressure and the flow path pressure determined by the hydraulic pressure of the wheel brake; the controller opens the control valve when the flow path pressure is greater than the required braking pressure; and the control valve is controlled based on the difference between the required braking pressure and the flow path pressure. Therefore, the method can always match the braking pressure of the wheel brake to the required braking pressure.

    차량용 브레이크 제어장치 및 제어방법을 개시한다. 본 개시의 일 실시예에 의하면, 작동유체를 저장하는 레저버(reservoir); 레저버와 연결되는 마스터 실린더(master cylinder); 마스터 실린더로부터 유압을 제공받도록 구성되는 휠브레이크(wheel brake); 레저버 및 휠브레이크와 연통하는 잔압제어 유압라인(residual pressure control hydraulic line); 잔압제어 유압라인 상에 설치되는 제어밸브(control valve); 휠브레이크에 요구되는 요구제동압을 생성하는 입력부(input unit); 및 제어밸브의 개방 정도를 제어하는 제어기(controller)를 포함하는 차량의 브레이크 제어방법에 있어서, 제어기가 휠브레이크의 유압에 의하여 정해지는 유로압력과 요구제동압의 압력차를 판단하는 과정; 유로압력이 요구제동압보다 큰 경우, 제어기가 제어밸브를 개방하는 과정; 및 요구제동압과 유로압력의 차이를 기초로 제어밸브를 제어하는 과정을 포함하는 차량용 브레이크 제어방법을 제공한다.
