PROBLEM TO BE SOLVED: To accurately determine damage to a component member of a vehicle bumper.SOLUTION: A collision detection device for a vehicle comprises: an acceleration sensor 22 for detecting an acceleration of a vehicle; a pressure sensor 48 provided to a vehicle bumper for determining a collision against a collided object and detecting a pressure in a space of a pressure tube having the space formed in it; and a control device 12 which, when an acceleration of not less than a predetermined threshold value has been detected by the acceleration sensor 22 and an increase in the pressure has been detected by the pressure sensor 48, determines that damage of such an extent that it affects next determination of collision has occurred to a component member of the vehicle bumper.SELECTED DRAWING: Figure 1

    【課題】車両用バンパの構成部材の損傷を正確に判定することを目的とする。【解決手段】車両の加速度を検出する加速度センサ22と、被衝突体への衝突を判定するために車両用バンパに設けられ、内部に空間が形成された圧力チューブの空間内の圧力を検出する圧力センサ48と、加速度センサ22によって予め定めた閾値以上の加速度が検出され、かつ圧力センサ48によって圧力の上昇が検出された場合に、次回の衝突判定に影響するレベルの損傷が車両用バンパの構成部材に発生したと判定する制御装置12と、を備える。【選択図】図1
