To determine operation ability without causing an operational issue.SOLUTION: An operation ability determination system 10 comprises: an information acquisition section 13 which acquires information on a size of a vehicle and steering angle data indicating a time series change in a steering angle of the vehicle; an evaluation value calculation section 16 which calculates a prediction error between a predicted steering angle, at a second time point later than a first time point on the basis of the time series steering angle data acquired by the first time point and calculates, and an actual steering angle acquired at the second time point and obtains an evaluation value indicating a magnitude of a deviation in steering operation of a driver on the basis of the calculated prediction error; a cognition function evaluation section 17 which compares the obtained evaluation value with a predetermined determination threshold and evaluates operation ability of the driver on the basis of a comparison result; and a setting section 14 which sets at least either a time interval between the first time point and the second time point or the determination threshold on the basis of the acquired information on a size.SELECTED DRAWING: Figure 2

    【課題】運転に支障をきたすことなく運転能力を判定する。【解決手段】運転能力判定システム10は、車両のサイズの情報とともに、車両の時系列の操舵角の変化を示す操舵角データを取得する情報取得部13と、第1時点までに取得された時系列の操舵角データに基づいて第1時点よりも後の第2時点で予測される操舵角と、第2時点で取得された実際の操舵角との間の予測誤差を算出し、算出された予測誤差に基づいて運転者の操舵のぶれの大きさを表す評価値を算出する評価値算出部16と、算出された評価値を所定の判定閾値と比較し、比較結果に基づいて運転者の運転能力を評価する認知機能評価部17と、取得されたサイズの情報に基づいて、第1時点から第2時点までの時間間隔および判定閾値の少なくとも一方を設定する設定部14と、を備える。【選択図】図2
