Abstract
In an air bag system of the type that inflates one air bag using a plurality of inflators, an air bag inflation control apparatus is provided that can make a proper determination of inflator activation mode and a correct decision to activate or not activate the inflators according to the severity of a collision. More specifically, the invention provides an activation control apparatus for an air bag system having a plurality of inflators for one air bag, which, upon detection of a vehicle collision, controls activation of the inflators in accordance with the severity of the collision, comprising: a first acceleration sensor 1, mounted in a position within a passenger compartment, for constantly detecting acceleration G at the mounting position; and a second acceleration sensor 2, mounted in a position within a crush zone in a forward part of a vehicle, for constantly detecting acceleration G' at the mounting position, and wherein: a decision to activate or not activate the plurality of inflators and determination of the activation mode of the inflators are determined by utilizing differences in characteristics among various values in various types of collision and by combining the …
