In order to avoid the false triggering and non- triggering of automotive airbags,an intelligent airbag con-troller is designed on the basis of genetic neural network model.Firstly,on the basis of a developed hardware sys-tem of airbag controller,a full- vehicle finite element model and a multi- rigid- body model of the occupant restraintsystem for the target vehicle type are established and validated.Secondly,the airbag initiation manner and the opti-mal ignition time are determined through simulation analysis.Then,an intelligent control algorithm of airbag is de-signed in light of improved genetic neural network model,with its effectiveness being finally verified by a sled test.Experimental results show that the designed intelligent airbag controller helps identify the collision dynamicscorrectly and predict the initiation time accurately.
