To prevent a steering angle recognized by a driver from being different from an actual steering angle when a driving mode is switched from an automatic driving mode to a manual driving mode.SOLUTION: A steering device 10 includes: a steering wheel 6 which is rotatable over an angle range exceeding 180° to each of left and right sides from a neutral position; a turning mechanism 11 which turns a wheel (3) so that a ratio K (=β/α) of a steering angle β to a turning angle α can be changed according to the steering angle β of the steering wheel 6; and a control device 15 which controls the ratio K of the turning mechanism 11. The control device 15 sets the ratio K to a first value (9, for instance) during traveling in a manual driving mode and sets the ratio K to a second value (3, for instance) smaller than the first value during traveling in an automatic driving mode. The second value is set so that the steering angle β corresponding to a maximum value of the turning angle α of a wheel stipulated by the turning mechanism 11 becomes less than 180°.SELECTED DRAWING: Figure 3
【課題】運転モードが自動運転モードから手動運転モードに切り替わるときに、運転者が認識する操舵角が実際の操舵角と相違することを防止する。【解決手段】操舵装置10は、中立位置から左右のそれぞれへ180°を超える角度範囲にわたって回転可能なステアリングホイール6と、ステアリングホイール6の操舵角βに応じ、操舵角βの転舵角αに対するレシオK(=β/α)を変更可能に車輪(3)を転舵する転舵機構11と、転舵機構11のレシオKを制御する制御装置15とを備える。制御装置15は、手動運転モードでの走行時にレシオKを第1の値(例えば、9)に設定し、自動運転モードでの走行時にレシオKを第1の値よりも小さな第2の値(例えば、3)に設定する。第2の値は、転舵機構11によって規定される車輪の転舵角αの最大値に対応する操舵角βが180°未満となるように設定される。【選択図】図3
