COLLISION DETECTION DEVICE FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a collision detection device for a vehicle capable of detecting even the direction of impact together with strength of the impact when a vehicle collides with the other object.SOLUTION: A collision detection device for a vehicle is provided with at least three units of deformation measurement devices stuck in a state of mutually separately placing a plurality of strain measurement elements on a belt-like sheet along it, in which at least one of the deformation measurement devices is stuck along its extension direction to a main part of a bumper having a main part and a side part connected via a bending part to respective both ends of the main part, and at least the other one of the deformation measurement devices is stuck in the orthogonal direction to the extension direction to the bending part of the bumper, and at least the other one of the deformation measurement devices is stuck along the extension direction to the side part.SELECTED DRAWING: Figure 2 【課題】車両が他物体と衝突したとき、衝撃の強さと共に衝撃の方向をも検知することができる車両用衝突検知装置を提供する。【解決手段】複数個のひずみ測定素子が帯状シートにそれに沿って相互に隔置された状態に貼り付けられた変形測定装置を少なくとも３個備え、変形測定装置の少なくとも一つは、主部と該主部の両端の各々に曲がり部を経て繋がった側部とを有するバンパーの主部にその延在方向に沿って貼着され、変形測定装置の少なくとも他の一つは、バンパーの曲がり部にその延在方向に直交する方向に貼着され、変形測定装置の少なくとも他の一つは、側部にその延在方向に沿って貼着されている車両用衝突検知装置。【選択図】図２
