To appropriately estimate an action probability of a driving action to be performed in response to a traffic state by a driver of an object vehicle to be a driving support object.SOLUTION: An action probability estimation device includes: a risk calculation section for calculating a risk index value being a numerical value indicating largeness of a collision risk between a traffic participant in the periphery of an object vehicle and the object vehicle; and a probability estimation section for estimating an action probability being the probability to perform a predetermined driving action by a driver in the object vehicle based on the risk index value and driver characteristics being the characteristics of the driver of the object vehicle. The driver characteristics include: a self-confidence level being a numerical value indicating the height of the self-confidence on his/her driving skill of the driver; and a situational performance level being a numerical value indicating largeness of a tendency to perform an action though recognizing danger.SELECTED DRAWING: Figure 3
【課題】運転支援の対象となる対象車両の運転者が交通状況に応じて実行し得る操縦行動の行動確率を、適切に推定する。【解決手段】行動確率推定装置は、対象車両の周囲の交通参加者と対象車両との衝突リスクの大小の程度を表す数値であるリスク指標値を算出するリスク算出部と、リスク指標値と、対象車両の運転者の特性である運転者特性と、に基づいて、運転者が、予め定めた所定の操縦行動を対象車両において実行する確率である行動確率を推定する確率推定部と、を備え、運転者特性は、運転者の、自分の運転スキルについての自信の高低の程度を表す数値である自信レベル、及び危険と知りながら行動を敢行する傾向の大小の程度を示す数値である状況的敢行性レベルを含む。【選択図】図3
