To estimate an emotion of a driver regardless of a situation around his/her own vehicle such as the presence/absence of an obstacle.SOLUTION: A driver emotion estimation system 1 comprises: an intersection passage determination unit 50a which detects that a vehicle has passed an intersection; a feature amount derivation unit 50b which derives a feature amount of a driving behavior of a driver during the passage when it is detected that the vehicle has passed the intersection; a deviation degree calculation unit 50c which calculates a deviation degree of the derived feature amount from a standard value; and an emotion estimation unit 50d which estimates an emotion of the driver during the passage in accordance with the calculated deviation degree. The feature amount derivation unit 50b derives a first feature amount based on a face image of the driver as the feature amount of the driving behavior, and the deviation degree calculation unit calculates a deviation degree of the first feature amount.SELECTED DRAWING: Figure 3
【課題】障害物の存否等の自車両の周辺状況に関わらず、運転者の感情を推定する。【解決手段】運転者感情推定システム1は、車両が交差点を通過したことを検出する交差点通過判定部50aと、通過がなされたと検出されると当該通過中における運転者の運転行動の特徴量を導出する特徴量導出部50bと、導出された特徴量の標準値からの逸脱度を算出する逸脱度算出部50cと、算出された逸脱度に応じて当該通過中における運転者の感情を推定する感情推定部50dと、を備える。特徴量導出部50bは、運転行動の特徴量として、運転者の顔画像に基づく第1の特徴量を導出し、逸脱度算出部は、第1の特徴量の逸脱度を算出する。【選択図】図3
