PROBLEM TO BE SOLVED: To quantitatively determine a degree of a sense of security obtained by an assistant front driver during high speed travel in a positional relation with an instrument panel.SOLUTION: A perceived line L passing through a first reference position α1 and a second reference position α2 is set in a vehicle side view. The first reference position α1 is on a line-of-sight direction δ1 of a first depression angle 1 in an assistant front driver J and defined as a position of a first forward distance (for example, 800 mm) where an actual distance matches with a perceived distance felt by the assistant front driver J. A second reference position α2 is on a line-of-sight direction δ2 of a second depression angle 2 which becomes a large depression angle and causes the actual distance and the perceived distance felt by the front assistant driver J to be matched and is set on a small distance (for example, 600 mm). An estimation value of a sense of security during high speed travel is decided according to a deviation of the distance between the perceived line L and data of the planned instrument panel. 【課題】インストルメントパネルとの位置関係において、高速走行時において助手席乗員がどの程度の安心感が得られるかを定量的に判断できるようにする。【解決手段】側面視において、第１基準位置α１と第２基準位置α２とを通る知覚ラインＬが設定される。第１基準位置α１は、助手席乗員Ｊにおける第１俯角 １の視線δ１上でかつ実際の距離と助手席乗員Ｊが感じる知覚距離とが一致する第１前方距離（例えば８００ｍｍ）の位置とされる。第２基準位置はα２は、大きい俯角となる第２俯角 ２の視線δ２上でかつ実際の距離と助手席乗員Ｊが感じる知覚距離とが一致すると共に小さい距離（例えば６００ｍｍ）の位置に設定される。知覚ラインＬと企画されたインストルメントパネルのデータとの距離の偏差に応じて、高速走行時での安心感の評価値が決定される。【選択図】 図７
