To provide a cognitive function evaluation system capable of evaluating a cognitive function level of an elderly driver based on a steering entropy value.SOLUTION: A system includes obtaining means for obtaining driving locus data on a vehicle driven by a person to be measured and measurement means for measuring a steering wheel rotation angle of the vehicle, and evaluates the cognitive function level of elderly drivers by a CPU that processes analysis means for analyzing the steering wheel rotation angle obtained by the measurement means and calculating a steering entropy value, spatiotemporal extracting means of extracting a specific time at a specific point while the vehicle is traveling, based on the driving locus data, and evaluation means for evaluating the cognitive function level of the person to be measured based on the steering entropy value at the specific point and the specific time.SELECTED DRAWING: Figure 4

    【課題】高齢ドライバーの認知機能レベルをステアリングエントロピー値に基づき評価することが可能である認知機能評価システムを提供する。【解決手段】測定対象者が運転する車両の走行軌跡データ取得手段と、前記車両のハンドル回転角の計測手段とを備え、前記計測手段で得られた前記ハンドル回転角を解析してステアリングエントロピー値を算出する解析手段と、前記走行軌跡データに基づいて、車両の走行中のうち特定地点の特定時間を抽出する時空間抽出手段と、前記特定地点・特定時間において、前記ステアリングエントロピー値に基づいて測定対象者の認知機能レベルを評価する評価手段、を処理するCPUにより、高齢ドライバーの認知機能レベルを評価する。【選択図】図4
