Abstract
A steering control device includes a steering reaction force control unit that applies a steering reaction force to a steering unit in accordance with a steering reaction force characteristic that is based on steering torque and steering angle of the steering unit in which the steering torque increases as the steering angle increases. Upon applying the steering reaction force to the steering unit, an offset amount is calculated that is greater as a curvature of the white line increases, and a suppression offset amount is calculated that applies a predetermined limit to a change rate of the offset amount. When the steering torque that is opposite of the curvature is detected upon offsetting the steering reaction force characteristic, the predetermined limit is changed to a greater limit than the predetermined limit to suppress an increase in the offset amount.
