Abstract: A motor driving redundancy device for an electronic parking brake includes a first motor-driving module configured to supply current to a motor, a first driver module configured to control the first motor-driving module, a second motor-driving module configured to drive the motor, a second driver module configured to control the second motor-driving module, a monitoring module configured to monitor a status of the first motor-driving module and the second motor-driving module, and a processor configured to, when a failure is detected in either the first motor-driving module or the second motor-driving module by the monitoring module, control at least one of the first motor-driving module or the second motor-driving module to drive the motor.

Abstract: A brake device for a vehicle includes a housing unit, a cylinder unit installed inside the housing unit, a motor unit connected to the cylinder unit and provides a rotational force, a screw shaft provided inside the cylinder unit and axially rotated by receiving the rotational force of the motor unit, a nut unit coupled to the screw shaft through a ball member and reciprocated in an axial direction of the screw shaft according to a rotation direction of the screw shaft, a piston unit coupled to the nut unit and moving in conjunction with the nut unit, and a bearing unit provided inside the cylinder unit, coupled to the screw shaft, and supporting an axial load when forming hydraulic pressure of the cylinder unit.

Abstract: An integrated electronic brake apparatus may include: a main control unit configured to receive one or more of an EPB signal, a value from a pedal sensor, a value from a cylinder pressure sensor, or a value from a wheel speed sensor, perform EPB control, drive a main brake valve and a brake motor for main braking of the vehicle according to an operation of a pedal, and drive an additional brake valve for additional braking; an auxiliary control unit configured to receive one or more of the EPB signal, the value from the pedal sensor, or the value from the wheel speed sensor when a driving signal is inputted thereto, perform EPB control, and control the operation of the EPB to perform a pseudo ABS operation; and a connection bus configured to connect the first and second areas mounted in one box, and transfer a signal transmitted/received between the main control unit and the auxiliary control unit.

Abstract: A master cylinder of a vehicle brake includes a housing, a motor, a screw, a moving piston, a guide, and a pressurizing part. The housing includes a port configured to move hydraulic fluid. The motor is connected to the housing and configured to supply rotation power. The screw is rotatably installed in the motor and configured to rotate in response to the rotation power. The moving piston is engaged with an outside of the screw, and is configured to move in a longitudinal direction of the housing in response to rotation of the screw. The guide is blocked by the housing and constrained from rotating, and is configured to constrain rotation of the moving piston and guide linear movement of the moving piston in the longitudinal direction. The pressurizing part is installed between the housing and the guide, and is configured to pressurize the guide via an elastic force.
