Steering system

Provided is a steering system capable of suppressing an increase in behavior of a vehicle caused by a steering device that steers wheels or a resonance between vehicle movement and steering of the wheels. The present invention is provided with a steering control unit (54) that executes a limit control when a determination unit (53) determines that a steering-related frequency is a value within a resonance frequency band. This limit control is for an actual steering angle that is an actual steering angle (i) such that the actual steering angle is constantly a prescribed value, (ii) such that the absolute value of the actual steering angle gradually decreases from the prescribed value, (iii) such that the frequency of the actual steering angle becomes outside the resonance band, or (iv) The control of the front wheel steering device (3) or the rear wheel steering device (4) is controlled such that the absolute value of the actual steering angle is smaller than the absolute value of the latest value of the targe
