PROBLEM TO BE SOLVED: To provide a vehicle collision detector capable of improving collision detection accuracy by reducing a clearance formed on the vehicle front side or rear side of a detection tube member within a groove portion formed in a bumper absorber.SOLUTION: A vehicle collision detector 1 comprises: a bumper absorber 2 provided in a vehicle bumper 7; a detection tube member 3 attached to a groove portion 2a formed in the bumper absorber 2 along a vehicle width direction, provided on a vehicle front side of a bumper reinforcement 9, and including a hollow portion 30a formed inside; and a pressure sensor 4 detecting an internal pressure of the hollow portion 30a of the detection tube member 3, and detects a collision of an object against the bumper 7 on the basis of a pressure detection result of the pressure member 4. The detection tube member 3 includes a bellows portion 31 that has a protrusion portion protruding from a surface on at least one of the vehicle front side and the vehicle rear side of an outer circumferential surface thereof.

    【課題】バンパアブソーバに形成された溝部内における検出用チューブ部材の車両前方側又は後方側に形成される隙間を小さくして衝突検知精度を向上させた車両用衝突検知装置を提供する。【解決手段】車両用衝突検知装置1は、車両のバンパ7内に配設されたバンパアブソーバ2と、バンパアブソーバ2に車幅方向に沿って形成された溝部2aに装着されると共にバンパレインフォースメント9の車両前方側に配設される内部に中空部30aが形成された検出用チューブ部材3と、検出用チューブ部材3の中空部30a内の圧力を検出する圧力センサ4とを有し、圧力センサ4による圧力検出結果に基づいてバンパ7への物体の衝突を検知する。そして、検出用チューブ部材3は、その外周面における車両前方側及び車両後方側のうち少なくとも一方の面に突設された突出部を有する蛇腹部31を備えている。【選択図】図2
