To estimate a driver torque corresponding to an operating state of an operation member.SOLUTION: A driver torque estimation device 130 is applied to a steering device 100 for turning a turning wheel 210 in response to an operation of an operation member 200 held to be operable by a combination of a plurality of mechanical elements. The driver torque estimation device 130 includes: a torque acquisition unit 131 that acquires the torque generated in the mechanical elements; a driver torque estimation unit 132 that, based on non-linear calculation, estimates driver torque, which is a force to be applied to the operation member 200 by a driver, by using the torque acquired from the torque acquisition unit 131; an operating-state specifying unit 133 that, based on movement information indicating a movement of the operation member 200, specifies a driver's operating state of the operation member; and an update unit 134 that, based on a specifying result of the operating-state specifying unit 133, updates a parameter value to be applied to the non-linear calculation that is used by the driver torque estimation unit 132.SELECTED DRAWING: Figure 2

    【課題】操作部材への操作状態に応じたドライバトルクの推定。【解決手段】複数の機械要素の組み合わせにより操作可能に保持される操作部材200の操作に応じて転舵輪210を転舵するステアリング装置100に適用されるドライバトルク推定装置130であって、機械要素に発生するトルクを取得するトルク取得部131と、運転者が操作部材200に加える力であるドライバトルクをトルク取得部131から取得したトルクを用いて非線形演算に基づき推定するドライバトルク推定部132と、操作部材200の動作を示す動作情報に基づき運転者の操作部材の操作状態を特定する操作状態特定部133と、操作状態特定部133の特定結果に基づき、ドライバトルク推定部132に用いられる非線形演算に適用されるパラメータ値を更新する更新部134と、を備えるドライバトルク推定装置130。【選択図】図2
