MOTOR CONTROL DEVICE AND ELECTRIC BRAKE DEVICE USING THE SAME, AND MOTOR CONTROLLING METHOD AND ELECTRIC BRAKE CONTROLLING METHOD USING THE SAME METHOD

An object of the invention is to provide a motor control device capable of realizing a redundancy while suppressing an increase in the number of parts and the number of connection signal lines. The invention includes angle sensors and for detecting a rotation angle of a motor, MPU for controlling the motor based on a stroke sensor and receiving the detected value of the angle sensor MPU for controlling the motor based on the stroke sensor and receiving the detected value of the angle sensor and communication units and for transmitting and receiving signals between the MPUs and The MPU includes an angle sensor failure detecting unit for detecting a failure of the angle sensors and according to the detected value of the angle sensor the detected value of the angle sensor received through the communication unit and a control angle of the motor created in response to the stroke sensor
