Abstract
A steering control device includes an electronic control unit. The electronic control unit is configured to calculate a target rotation angle of a shaft rotating with a turning operation of turning wheels based on a steering angle of a steering wheel acquired from a rotation angle of a reaction motor, to calculate a command value based on the target rotation angle and a steering torque acquired from a torsion angle of a torsion bar twisting with an operation of the steering wheel, and to compensate for the torsion angle by adding the torsion angle as a compensation value to the steering angle. The electronic control unit is configured to change a value of the torsion angle that is added to the steering angle according to a degree of change of a state variable used to calculate the command value.
