To enable it to be accurately determined that a door is closed with a strong force, by a simple and inexpensive constitution.SOLUTION: An air bag ECU 3a determines that centripetal acceleration associated with strong closing of a door is detected by right and left G sensors 2b and 2a, which are provided on right and left hinge doors of a vehicle, respectively. In this case, not a broadside collision against a vehicle 1 but the strong closing of the door is determined. When the presence of the strong closing of the door is determined, a threshold for determining whether or not acceleration detected by horizontal detection functions of the right and left G sensors 2b and 2a is caused by the broadside collision is switched to a threshold higher than usual.SELECTED DRAWING: Figure 1

    【課題】簡単かつ安価な構成により、ドア強閉を精度よく判別できるようにする。【解決手段】車両の左右のヒンジドアにそれぞれ設けた左側、右側Gセンサ2a,2bによりドア強閉に伴う向心加速度が検出されたとエアバッグECU3aにより判定されたときに、車両1への側面衝突ではなくドア強閉と判定する。そして、ドア強閉ありと判定したときに、左側、右側Gセンサ2a,2bの左右方向への検出機能により検出される加速度が側面衝突によるものかどうかを判断するためのしきい値を通常よりも高く切り換える。【選択図】図1
