The invention belongs to the technical field of vehicle manipulation and control, and particularly relates to a calibration and fault identification method for a manned and unmanned line-selection brake device, the line-control brake device comprises a brake pedal, an angle sensor, a hydraulic pressure reducing valve, an electro-hydraulic proportional pressure reducing valve and a hydraulic control direction valve, and the requirements of electric control and manual mechanical operation can be met at the same time. According to the calibration method, according to the flow characteristics of the hydraulic pressure reducing valve and the electro-hydraulic proportional pressure reducing valve, the oil filling time can be shortened to the maximum extent, and meanwhile the brake valve has the fault recognition capacity. The brake-by-wire device and the calibration method can improve the brake response time on the basis of ensuring the safety of the drive-by-wire, and have a fault recognition function.
