<p>PROBLEM TO BE SOLVED: To provide an operation control device appropriately acting even on a rough road, during hammering, and the like. SOLUTION: An operation control device for an air bag device provided with a plurality of inflators for one air bag has a first acceleration sensor 1 for constantly detecting acceleration G of an installation pant in a cabin, and a second acceleration sensor 2 installed in a front crash zone of a vehicle body so as to constantly detect acceleration G' of the installation part. On the basis of characteristic difference in various collision forms based on the first time integrated value V time-integrated on the basis of acceleration signals from the first acceleration sensor 1, the second time integrated value V' time- integrated on the basis of acceleration signals from the second acceleration sensor 2, and the integrated value difference (Vd=V'-V) between the second time integrated value and the first time integrated value, or the variation Gd=d(Vd/dt) of the integrated value difference, these values are appropriately combined to judge the necessity of operating a plurality of inflators and the operating form of the inflators.</p> |
