Abstract
A motor control device is provided which achieves redundancy while suppressing an increase in the number of parts and connection signal lines. The device includes angle sensors for detecting a rotation angle of a motor, a first microcomputer unit for controlling the motor based on a stroke sensor and receiving the detected value of the angle sensor, a second microcomputer unit for controlling the motor based on the stroke sensor and receiving the detected value of the angle sensor, and communication units for transmitting and receiving signals between the microcomputer units. The first microcomputer unit includes an angle sensor failure detecting unit for detecting a failure of the angle sensors, according to the detected value of the angle sensors, and a control angle of the motor created in response to the stroke sensor.
