Hydraulic brake for vehicle and control method therefor

A method of controlling a hydraulic brake for a vehicle including a first brake device and a second brake device configured to supply hydraulic pressure to wheel brakes of the vehicle, and a control unit including a first controller configured for controlling the first brake device and a second controller configured for controlling the second brake device, the method comprising:

• receiving, by the control unit, information for determining a status of the first brake device;
• determining, by the control unit, whether the first brake device is normally operated using the information for determining the status of the first brake device;
• and
• controlling, by the control unit, at least one of the first brake device and the second brake device to decrease a hydraulic pressure loss amount in the wheel brakes when the control unit concludes that the first brake device is not normally operated,
• wherein the receiving of the information for determining the status of the first brake device includes:
• receiving from the second brake device, by the control unit, information about hydraulic pressure supplied to the wheel brakes by the first brake device,
• wherein the method further comprises:
• determining, by the first controller, whether all of components of the first brake device are abnormally operated when the control unit concludes that the first brake device is not normally operated,
• wherein when the first controller concludes that all of the components of the first brake device are abnormally operated, the controlling of the at least one of the first brake device and the second brake device includes controlling the second brake device by the second controller to decrease the hydraulic pressure loss amount of the wheel brakes.
