Abstract
A steering device includes: an electric motor configured to apply a driving force to cause a wheel of a vehicle to roll; a transmission unit configured to transmit the driving force of the electric motor to the wheel; an input determination unitconfigured to determine whether an excessive external force equal to or greater than a predetermined force is input, or likely to be input, to the transmission unit via the wheel while the electric motor is applying the driving force; and a final target current setting unitconfigured to, in response to the input determination unitdetermining that the excessive force is input, or likely to be input, to the transmission unit, reduce the driving force of the electric motor so that a load on the transmission unit does not exceed an upper limit that is preset according to strength of the transmission unit.
