To improve a feeling of operation of a driver at the time of an operation of increasing the turning of a steering wheel and at the time of an operation of returning the steering wheel, in a steering system of a vehicle in which a steering device including the steering wheel and a turning device for turning a wheel are connected by a signal.SOLUTION: A control device for controlling a reaction force device that applies reaction force torque to a steering wheel sets a virtual end angle, corresponding to a turning limit of a turning device, to a steering angle. When the steering angle approaches the virtual end angle, the control device gradually increases the reaction force torque as the steering angle approaches the virtual end angle. On the other hand, when the steering angle is away from the virtual end angle, the control device reduces the reaction force torque with respect to a change in the steering angle, with a gradient steeper than a gradient of a change in the reaction force torque with respect to a change in the steering angle when the steering angle approaches the virtual end angle.SELECTED DRAWING: Figure 3

    【課題】ステアリングホイールを含むステアリング装置と車輪を転舵する転舵装置とが信号によって接続される車両の操舵システムにおいてステアリングホイールの切り増し操作時と切り戻し操作時の両方において運転者の操作感を向上させる。【解決手段】ステアリングホイールに反力トルクを作用させる反力装置を制御する制御装置は、転舵装置の転舵限界に対応する仮想エンド角を操舵角に対して設定する。そして、操舵角が仮想エンド角に近づく場合、制御装置は、操舵角が仮想エンド角に近づくに連れて反力トルクを徐々に増大させる。一方、操舵角が仮想エンド角から遠ざかる場合、制御装置は、操舵角が仮想エンド角に近づく場合の操舵角の変化に対する反力トルクの変化の勾配よりも急な勾配で操舵角の変化に対して反力トルクを減少させる。【選択図】図3
