To provide a driver-supporting device capable of estimating factors that cause diminishment of a driver's cognitive function, and to provide a driver-supporting system and a driver-supporting method therefor.SOLUTION: A driver-supporting device comprises: a driving state detection part for detecting at least one of a driver's vehicle-driving action, biological information during driving, and behavior of a vehicle; a cognitive function score calculation part for calculating a numerical value indicating a level of a driver's cognitive function, based on a detection result of the driving state detection part; a cognitive function property analysis part for analyzing the calculated numerical value as a cognitive function property related to one or more different brain functions; a cognitive function storage part for time-sequentially storing the numerical values calculated by the cognitive function score calculation part with respect to the same driver, and a result analyzed by the cognitive function property analysis part; a cognitive function diminishment factor estimation part for estimating main factors among a plurality of variable factors that cause diminishment of a driver's cognitive function, based on the stored content; and a driver-supporting part for supporting the driver based on an estimation result or information corresponding to the estimation result.SELECTED DRAWING: Figure 5

    【課題】運転者の認知機能の低下要因を推定することができるドライバー支援装置、ドライバー支援システム及びドライバー支援方法を提供する。【解決手段】ドライバー支援装置は、運転者による車両の運転行動と、運転中の生体情報と、車両の挙動のうち少なくとも1つを検知する運転状態検知部と、運転状態検知部の検知結果に基づいて、運転者の認知機能の高さを示す数値を算出する認知機能スコア算出部と、算出された数値を、1以上の異なる脳機能に関連する認知機能特性として分析する認知機能特性分析部と、認知機能スコア算出部が算出した同じ運転者に対する数値と認知機能特性分析部の分析結果とを時系列で記憶する認知機能記憶部と、記憶内容に基づいて、運転者の認知機能の低下を引き起こす複数の変動要因の中の主要因を推定する認知機能低下要因推定部と、推定結果又は推定結果に応じた情報をもとに運転者を支援するドライバー支援部と、を備える。【選択図】図5
