To provide a control device for a steering device, a control method for a steering mechanism and a steering system capable of suppressing the deterioration of a vehicle behavior while suppressing the discomfort feeling of a driver.SOLUTION: A control device according to the present invention is provided for a vehicle that includes a steering device configured to be able to independently control the turning angle of a wheel relative to the operated amount of a steering operation input member, and inputs, regardless of the operated amount of the steering operation input member, a control signal for returning the turning angle of the wheel to a neutral position or therearound to a steering actuator when a physical quantity relating to the actual yaw rate of the vehicle is greater than a physical quantity relating to an estimated yaw rate based on the operated amount of the steering operation input member and of the running state of the vehicle.SELECTED DRAWING: Figure 2 【課題】運転者の違和感を抑えながら車両挙動の悪化を抑止できる、ステアリング装置の制御装置、ステアリング機構の制御方法、及びステアリングシステムを提供する。【解決手段】本発明に係る制御装置は、操舵操作入力部材の操作量に対して車輪の操舵角を独立に制御可能に構成されたステアリング装置を備えた車両に設けられ、車両の実ヨーレイトに関する物理量が、操舵操作入力部材の操作量と車両の走行状態とに基づく推定ヨーレイトに関する物理量よりも大きいときに、操舵操作入力部材の操作量に係わらず、車輪の操舵角を中立位置付近に切り戻すための制御信号を操舵アクチュエータへ出力する。【選択図】図２
