PROBLEM TO BE SOLVED: To provide a pedestrian collision detection device which reduces temperature dependence to stabilize the operation.SOLUTION: A pedestrian collision detection device 11 of the invention includes: a bumper support member 18; a foam material 20 disposed on a front surface of the bumper support member 18; and a duct 38 which guides air existing outside of a vehicle 10 into a hollow part 21 of the foam material 20. The structure allows outer air to flow into the hollow part 21 of the foam material 20 when the vehicle 10 travels. Thus, a temperature of the foam material 20 is decreased to allow the pedestrian collision detection device 11 to properly work.SELECTED DRAWING: Figure 4
【課題】温度依存性を減少させることで動作が安定化された歩行者衝突検知装置を提供する。【解決手段】本発明の歩行者衝突検知装置11は、バンパ支持部材18と、バンパ支持部材18の前面に配置されたフォーム材20と、車外の空気をフォーム材20の中空部21に導くダクト38とを備えている。これにより、車両10の走行時に外気をフォーム材20の中空部21に通風させることができるので、フォーム材20の温度を低下させ、歩行者衝突検知装置11を適正に動作させることが出来る。【選択図】図4
