Abstract
A computer based method for activating a vehicular safety device for passenger protection is disclosed. The method uses two front-end acceleration sensors and a passenger compartment sensor. When a collision situation is sensed, current acceleration data is integrated to produce velocity and displacement values for the sensor locations. The velocity and displacement values are selectively used in at least three vehicle collision mode analyses. Examples of such collision modes are a full frontal mode, an angle mode and an offset deformable barrier mode. Each collision mode has sub-modes corresponding to the desired levels of airbag inflation. When appropriate threshold values are exceeded, device activation for one or more activation stages is initiated.
