Abstract
A computer based method for activating a vehicular safety device for passenger protection is disclosed. The method uses a centrally located front-end acceleration sensor and a passenger compartment sensor. When a crash situation is sensed, current acceleration data is integrated to produce velocity values for both sensor locations. Actual displacement values for the front-end sensor are calculated as well as displacement values based on absolute values of acceleration of that sensor. The velocity and displacement values are selectively used in at least three vehicle crash mode analyses. Examples of such crash modes are full frontal-like modes, pole-like modes and angle-like modes. When appropriate threshold values are exceeded, device activation for one or more activation stages is initiated.
