Abstract
A steering device includes a steering member, a steering operation mechanism, a reactive force motor, a steering motor that drives the steering operation mechanism, a steering torque sensor, and an electronic control unit. The electronic control unit sets a manual steering angle command value. The electronic control unit computes a reactive-force-related composite angle command value. The electronic control unit computes a steering-related composite angle command value based on a steering-related automatic steering angle command value and the manual steering angle command value. The electronic control unit causes a rotational angle of the reactive force motor to follow the reactive-force-related composite angle command value. The electronic control unit causes a rotational angle of the steering motor to follow the steering-related composite angle command value. The electronic control unit estimates a first disturbance torque.
