A steering system for a vehicle according to an example in the present disclosure includes a steering mechanism, which is mechanically disconnected from the steering wheel, to cause a turning wheel to be turned by a turning motor, and a control device that provides a motor command value to the turning motor. The control device has a control system including a feed-forward model for converting a target turning angle to a feed-forward value of a motor command value, and a disturbance observer including a inverse model of a model of a steering motor. Transfer functions respectively describing the feed-forward model and the model of the disturbance observer include a variable coefficient. The control device changes the variable coefficient based on information about road reaction force.
