Abstract
A steering control apparatus includes: a friction torque setting mechanism setting a friction torque value to be applied to a steering based on information representing a status of a vehicle; a target steering angle setting mechanism setting a target steering angle based on the set friction torque value; an adding friction torque setting mechanism setting an adding friction torque based on a deviation between the set target steering angle and a steering angle; and a steering friction torque controller controlling a friction torque applied to the steering by an actuator based on the set adding friction torque.
