PROBLEM TO BE SOLVED: To provide a driving support device which can ensure traveling safety and prevent hindrance to interaction between occupants when there are a plurality of occupants.SOLUTION: A driving support device 1 comprises: a deviation determination part 22 for determining reduction in safety of a vehicle on the basis of a traveling state of the vehicle; and an alarming device 4 for alarming a driver when a determination value of the deviation determination part 22 has exceeded a determination threshold value. It comprises: a voice interaction device 10 which acquires voice of interaction between the driver and an occupant: a determination threshold value setting part 23 which makes a determination threshold value when the driver is speaking to an occupant greater than a determination threshold value when the driver is listening to an occupant; and an enthusiasm level determination part 24 for determining an enthusiasm level of the driver in the interaction on the basis of words that are included in the voice of the driver and the occupant who are engaged in the interaction. It reduces the determination threshold value when it is determined that the enthusiasm level of the driver in the interaction is high by the enthusiasm level determination part 24.SELECTED DRAWING: Figure 1 【課題】複数の乗員が乗車したときの走行安全性確保と乗員間の対話阻害防止とを両立することができる運転支援装置を提供する。【解決手段】車両の走行状態に基づいて車両の安全性の低下を判定する逸脱判定部２２と、この逸脱判定部２２の判定値が判定閾値を超えたときに運転者に警報を行う警報装置４とを備えた運転支援装置１である。運転者と同乗者との対話の音声を取得する音声対話装置１０と、運転者が同乗者に発話しているときの判定閾値を運転者が同乗者の発話を傾聴しているときの判定閾値よりも大きくする判定閾値設定部２３と、対話中の運転者及び同乗者の音声に含まれたワードに基づいて運転者の対話に対する熱中度を判定する熱中度判定部２４とを備える。熱中度判定部２４により、運転者の対話に対する熱中度が高いと判定されたとき、判定閾値を小さくする。【選択図】図１
