To enable accurate discrimination by a simple and inexpensive constitution when discriminating between a broadside collision and an offset collision.SOLUTION: Horizontal acceleration is detected by a G sensor 4b for safing in an early phase of collision in association with generation of rotation of a vehicle 1 due to an offset collision of the vehicle 1. In this case, it is determined that the collision is not the broadside collision against the vehicle 1 but the offset collision. A threshold for determining whether or not acceleration detected by B pillar and C pillar sensors 2a, 2b, 3a and 3b after the early phase of the collision is caused by the broadside collision is changed from a usual sensitive threshold to an insensitive threshold higher than the sensitive threshold, by an air bag ECU 4b.SELECTED DRAWING: Figure 1

    【課題】側面衝突とオフセット衝突とを判別する上で、簡単かつ安価な構成により精度よく判別できるようにする。【解決手段】車両1のオフセット衝突が生じて車両1に回転が生じるのに伴い、衝突初期においてセーフィング用Gセンサ4bにより左右方向の加速度が検出されたときに、その衝突は車両1への側面衝突ではなくオフセット衝突であると判断し、エアバッグECU4bにより、衝突初期の後にBピラー、CピラーGセンサ2a,2b,3a,3b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、通常の敏感しきい値からこれよりも高い鈍感しきい値に切り換える。【選択図】図1
