- 車両の衝突時の加速度を検出する加速度検出手段と、
該加速度検出手段の検出結果から得られる衝突波形に基づいて車両の衝突形態を判別する衝突形態判別手段と、
予め類別した車両の衝突形態に対応する複数の基準波形が記憶された記憶手段と、を備え、
前記衝突形態判別手段が、前記記憶手段に記憶された基準波形と、前記加速度検出手段の検出結果から得られる衝突波形との相似度に基づいて、車両の衝突形態を判別すると共に、前記基準波形上に設定した複数の特徴点と前記衝突波形上に設定した複数のサンプリング点との残差の和に基づいて前記相似度を求めることを特徴とする衝突判別装置。 - 請求項1に記載の衝突判別装置において、
前記残差は、前記特徴点と前記サンプリング点との最小差であることを特徴とする衝突判別装置。 - 請求項1又は2に記載の衝突判別装置において、
前記衝突形態判別手段は、前記衝突波形及び前記基準波形を正規化した上で前記相似度を求めることを特徴とする衝突判別装置。 - 請求項1〜3の何れか一項に記載の衝突判別装置において、
前記衝突波形は、前記加速度検出手段の検出結果から算出された前記車両の変位と、当該車両の加速度とに基づいて形成されたものであることを特徴とする衝突判別装置。
