Abstract: Assist torque or reaction force torque with little unnatural feeling to a driver is applied. An ECU includes: a control amount calculation section that calculates a control amount for controlling magnitude of the assist torque or the reaction force torque with reference to steering torque applied to a steering member; and a control amount correction section that corrects the control amount calculated by the control amount calculation section with reference to a lateral G of a vehicle body, a steering angle of the steering member, and a steering angle speed of the steering member.

Abstract: A steering control device which applies an assist torque or a reaction torque to a steering member operated by a driver, includes: a torque loss estimation unit which estimates torque loss; and a correction amount calculation unit which calculates a correction amount according to a rack axial force estimation value calculated based on a roll rate when the torque loss estimation unit estimates the torque loss.
