Claim:
1. A steering control device comprising: a steering unit mechanically separated from a turning unit for turning a turnable wheel and that receives steering input from a driver; a steering reaction force control unit programmed to set a steering reaction force characteristic based on a steering torque of the steering unit and a steering angle of the steering unit in which the steering torque increases as the steering angle of the steering unit increases, and apply a steering reaction force to the steering unit based on the steering reaction force characteristic; a curvature detection unit programmed to detect a curvature of a white line; an offset unit programmed to calculate an offset amount that increases as the detected curvature increases and that offsets the steering reaction force characteristic such that a neutral point of the steering is moved in a curve direction according to a magnitude of the detected curvature; a lateral acceleration detection unit programmed to detect a lateral acceleration of a host vehicle; and an offset suppression unit programmed to suppress an increase in the offset amount more as an absolute value of the detected lateral acceleration increases and to hold a maximum value of the absolute value of the detected lateral acceleration when the detected curvature is equal to or greater than a predetermined curvature.
