Abstract
A steering control device is applied to a steer-by-wire system in which a steering mechanism and a turning mechanism are mechanically separated. The steering control device applied to the steer-by-wire system controls a drive of a steering motor that functions as a reaction motor that applies reaction torque to a steering wheel. A steering wheel lock calculating unit of the steering control device performs a steering wheel lock drive control for calculating a drive command so as to output a lock torque for maintaining a rotation stop state of the steering wheel by energizing the steering motor when a predetermined condition is satisfied while a vehicle is parked or stopped. A power converter converts power supply electric power according to the drive command calculated by the steering wheel lock calculating unit and supplies the electric power to the steering motor.
