Abstract

A brake device for a vehicle including: a master cylinder unit configured to generate hydraulic pressure by pressing of a pedal; a reservoir connected to the master cylinder unit and configured to store oil; a driving unit operated by movement of the pedal and configured to receive electric energy through a plurality of batteries to supply rotation power; a hydraulic generation unit configured to rotate by receiving the rotation power of the driving unit and generate hydraulic pressure by rotation of a plurality of rotors; wheel cylinder units configured to receive the hydraulic pressure generated by the hydraulic generation unit and constrain rotation of wheels; and a control unit configured to detect whether the driving unit normally operates and control an operation of the driving unit to supply the hydraulic generation unit with the rotation power in an event of abnormal operation of the driving unit.
