This electric power steering device is provided with: a first control device capable of controlling a first actuator of a steering device; a second control device capable of controlling a second actuator of the steering device; and a third control device capable of switching between connection and interruption with at least one of the first actuator and the second actuator, the electric power steering device interrupting the connection between the first control device and the first actuator, connecting the third control device and the first actuator, and interrupting the connection between the third control device and the second actuator when the first control device fails. If the second control device fails, the electric power steering device interrupts the connection between the second control device and the second actuator, and connects the third control device and the second actuator. As a result, even if one of the plurality of control devices fails, a decrease in the total output of the electric motor can be suppressed.

    本发明所涉及的电动动力转向装置具有:第一控制装置,能够控制转向装置的第一致动器;第二控制装置,能够控制所述转向装置的第二致动器;以及第三控制装置,能够切换与所述第一致动器和所述第二致动器的至少一个连接和遮断,若所述第一控制装置故障,则所述电动动力转向装置遮断所述第一控制装置和所述第一致动器的连接,连接所述第三控制装置和所述第一致动器,若所述第二控制装置故障,则所述电动动力转向装置遮断所述第二控制装置和所述第二致动器的连接,连接所述第三控制装置和所述第二致动器。由此,即使多个控制装置中的一个故障,也能够抑制电动马达的总输出下降。
