Abstract
A steering control apparatus includes a steering angle feedback processing unit and an operation signal generation processing unit that operate a reaction force actuator to adjust a steering angle to a target steering angle that is a target value for the steering angle based on feedback control, an ideal-axial-force calculation unit that calculates an ideal axial force, a road-surface-axial-force calculation unit that calculates a road surface axial force, an axial-force allocation calculation unit that calculates a base reaction force in which the ideal axial force and the road surface axial force are allocated in a predetermined ratio, and a target steering angle calculation processing unit that sets a target steering angle based on the base reaction force. The steering angle feedback processing unit feeds back the target steering angle in which road surface information is incorporated through the road surface axial force, so that the steering angle is controlled.
