Zusammenfassung:	To provide a motor control device capable of realizing redundancy while suppressing an increase in the number of parts and the number of connection signal lines.SOLUTION: A motor control device comprises: angle sensors 102 and 103 for detecting a rotation angle degree of the motor; a MPU 107 that controls the motor based on a stroke sensor 117 and receives a detection value of the angle sensor 102; a MPU 108 that controls the motor based on the stroke sensor 117 and receives a detection value of the angle sensor 103; and communication portions 115 and 116 that transmit and receive signals between the MPUs 107 and 108. The MPU 107 includes an angle sensor failure detection portion 114 that detects failures of the angler sensors 102 and 103 from the detection value of the angular sensor 102, the detection value of the angular sensor 103 received through the communication portion 115, and a control angle of the motor generated according to the stroke sensor 117.SELECTED DRAWING: Figure 1 【課題】部品点数および接続信号線数の増加を抑えて冗長化を実現することができるモータ制御装置を提供する。【解決手段】モータの回転角度を検出する角度センサ１０２、１０３と、ストロークセンサ１１７に基づいてモータを制御すると共に角度センサ１０２の検出値を受信するＭＰＵ１０７と、ストロークセンサ１１７に基づいてモータを制御すると共に角度センサ１０３の検出値を受信するＭＰＵ１０８と、ＭＰＵ１０７，１０８間で信号の送受信を行う通信部１１５，１１６を備える。ＭＰＵ１０７は、角度センサ１０２の検出値と、通信部１１５を介して受信した角度センサ１０３の検出値と、ストロークセンサ１１７に応じて生成されたモータの制御角とから、角度センサ１０２、１０３の故障を検出する角度センサ故障検出部１１４を備える。【選択図】図１
