Abstract
If deceleration in excess of a predetermined value is detected (step,in FIG.2), a speed integral value &Dgr;V as time integration of the deceleration is calculated (step,in FIG.2). A segment length of a characteristic curve of the speed integral value &Dgr;V in a predetermined range is calculated (steps,in FIG. 2). If it is decided that the segment length is smaller than a predetermined value l,(step,in FIG. 2), the crash is decided to be a low speed crash, etc. other than a soft crash. An air bag is inflated if the speed integral value &Dgr;V exceeds a predetermined threshold value V,, whereas the speed integral value &Dgr;V is incremented by a predetermined value &agr; (step,in FIG. 2) if it is decided that the segment length exceeds l,(step,in FIG. 2). Then, if it is decided that the speed integral value &Dgr;V exceeds the threshold value V,(step,in FIG. 2), inflation of the air bag is executed with detection of a soft crash.
