摘要

If an impact acceleration Gt in excess of a predetermined value is detected (step 102), a speed integral value &Dgr;V is calculated (step 110) and a length of a line segment of the impact acceleration with a passage of time is calculated (steps 112, 114). If a rate of an increment of the speed integral value &Dgr;V to the length of the line segment within a predetermined interval is smaller than a predetermined value R, it is decided that resonance is caused. Then, it is decided (step 122) whether or not the speed integral value &Dgr;Vt exceeds a new threshold value which is set on the more negative side from a threshold value &Dgr;VTH which is defined by V(G), by a predetermined value &agr; (step 120). If it is decided that the speed integral value &Dgr;Vt exceeds the new threshold value, an inflation of an air bag is carried out (step 124).
