  • Electric power steering apparatus
    Patent number: 8967321
    Abstract: An electric power steering apparatus includes an electric motor configured to apply an assist torque to an steering system of a motor vehicle, a rotational quantity detection unit for detecting a rotational quantity of the electric motor while the rotational quantity detection unit is in a wake-up state, and a counter electromotive voltage detection unit for detecting a counter electromotive voltage of the electric motor. When a main power supply of the electric power steering apparatus is turned off, the rotational quantity detection unit enters into a sleep state, and when a prescribed condition is established based on the counter electromotive voltage detected by the counter electromotive voltage detection unit, the rotational quantity detection unit transitions from the sleep state to the wakeup state.
