To enable smooth handover in a situation in which automatic driving is difficult, and to secure the comfort of the automatic driving by reducing a burden for allowing a driver to correctly grasp the situation of the automatic driving and a surrounding situation.SOLUTION: An information presentation device for a vehicle grasps time allowance until interference with each of a plurality of objects recognized by a system, extracts important objects to which a driver has to pay attention among the plurality of recognized objects on the basis of the time allowance, and outputs objects other than the important objects in an expression form weaker than in the important objects in presenting the recognized information to the driver. The driver can limit the direction of a monitoring object because the driver can intuitively and immediately grasp a situation on the basis of the narrowing-down of the object and the use of simple expression. When the time allowance of a TTC or the like is reduced due to a lane change of each object, the object is preferentially selected and presented as an important object.SELECTED DRAWING: Figure 4

    【課題】自動運転が難しい状況で円滑なハンドオーバを可能にすると共に、運転者が自動運転の状況および周囲の状況を正しく把握するための負担を軽減し、自動運転の快適性を確保すること。【解決手段】システムが認識している複数の対象物の各々に対する干渉までの時間余裕を把握し、認識している複数の対象物の中から運転者が注意すべき重要対象物を前記時間余裕に基づいて抽出し、認識している情報を運転者に提示する際に、重要対象物以外の対象物を、重要対象物よりも弱い表現形態で出力する。対象物の絞り込みと、簡易表現の利用により、運転者は状況を直感的に瞬時に把握可能になり、監視対象の方向も限定できる。各対象物の車線変更に伴ってTTC等の時間余裕が小さくなった場合に、これを重要対象物として優先的に選択し提示する。【選択図】図4
