ABSTRACT:
If the impact acceleration G which exceeds the predetermined threshold value G.sub.TH is detected within a predetermined time (see step 124 in FIG. 2) after the speed integral value .DELTA.V which exceeds the predetermined threshold value V.sub.TH has been detected (see step 112 in FIG. 2), it is decided that such impact acceleration is caused by the underfloor interference or the seat slide and therefore the side air bag system is not started (see step 126 in FIG. 2). In contrast, if the impact acceleration G which exceeds the predetermined threshold value G.sub.TH is not detected within the predetermined time (see step 124 in FIG. 2) after the speed integral value .DELTA.V which exceeds the predetermined threshold value V.sub.TH has been detected (see step 112 in FIG. 2) it is decided that such impact acceleration is caused by the true clash and therefore the side air bag system is started (see step 120 in FIG. 2).
