  • ELECTRIC POWER STEERING DEVICE
    Publication number: 20230001980
    Abstract: An electric power steering device includes a motor, a motor controller, first and second power source circuits, a power source switching circuit, and a voltage detector. The power source switching circuit is configured to switch between a first state in which the motor controller receives electric power from the first power source circuit but is cut off from the second power source circuit, and a second state in which the motor controller receives electric power from the second power source circuit but is cut off from the first power source circuit. The voltage detector is configured to detect the voltage of the first power source circuit. The power source switching circuit is configured to select the second state in a case where the voltage of the first power source circuit is less than or equal to a predetermined value, and select the first state in cases other than the case.
