Abstract

See full text

In a steering control device configured to control a steering system where a steering torque required for steering a steering wheel is changed using a motor torque, a processing circuit includes a first calculation situation where a calculational hysteresis component for adding a first hysteresis characteristic to a torque component is calculated and a second calculation situation where the calculational hysteresis component for adding a second hysteresis characteristic to the torque component is calculated. In the second calculation situation after change from the first calculation situation, the processing circuit calculates a value corresponding to an origin in the second hysteresis characteristic at a time when the calculational hysteresis component enabling a value of the calculational hysteresis component at a timing of the change from the first calculation situation to be maintained is calculated, and calculates the calculational hysteresis component using the calculated value as the origin.
