摘要： An object of the present invention is to provide a steering control device capable of reducing a steering amount while securing operability of a driver according to a traveling condition. A steering control device 61 forming a steer-by-wire system, which has no physical connection between a steering shaft by a driver and an actual steered angle of a vehicle wheel, the steering control device including an actual steered angle calculation unit 74 that determines the actual steered angle based on a steering angle and a steering torque generated on the steering shaft. The actual steered angle calculation unit 74 controls the actual steered angle based on the steering torque in a region where the steering angle is equal to or smaller than a predetermined value, and controls the actual steered angle based on a parameter different from the steering torque when the steering angle is larger than the predetermined value or a changed steering torque gain from when the steering angle is smaller than the predetermined value.
