To provide a vehicle collision determination device which can more surely suppress pressure fluctuation in a sensor tube when a road obstruction other than a pedestrian collides with a bumper.SOLUTION: A vehicle collision determination device comprises: a bumper beam 10 extended in a vehicle width direction; a bumper face 20 which is arranged in front of the bumper beam 10 and is extended in the vehicle width direction; an impact absorbing member 30 arranged between the bumper beam 10 and the bumper face 20; and a sensor tube 40 arranged between the impact absorbing member 30 and the bumper beam 10. The impact absorbing member 30 is formed in such a manner that its lower end height RH at its rear end is lower than its lower end height FH at its front end, and the sensor tube 40 is arranged in a lower position than the lower end height FH at the front end of the impact absorbing member 30.SELECTED DRAWING: Figure 3
【課題】歩行者以外の路上障害物がバンパに衝突した際に、センサチューブ内の圧力変動をより確実に抑制することのできる車両用衝突判定装置を提供する。【解決手段】車幅方向へ延びるバンパビーム10と、バンパビーム10の前方に配置され車幅方向へ延びるバンパフェース20と、バンパビーム10とバンパフェース20の間に配置される衝撃吸収部材30と、衝撃吸収部材30とバンパビーム10の間に配置されるセンサチューブ40と、を備えた車両用衝突判定装置において、衝撃吸収部材30は、前端における下端高さFHよりも、後端における下端高さRHが低く形成され、センサチューブ40は、衝撃吸収部材30の前端における下端高さFHよりも低い位置に配置される。【選択図】図3
