Abstract

A sensing algorithm for a dual stage airbag system is disclosed which applies a biased severity measure BSM to determine no-deployment, single-stage deployment or two-stage deployment of an airbag. A biased severity measure uses a bias factor to make a chosen severity measure in favor of the robustness or sensitivity of the algorithm, as desired. The sensing algorithm also employs a predicted occupant movement POM which must reach a preset occupant movement threshold before the biased severity measure is compared with first and second preset severity thresholds for determining actuation of the first and second stages of airbag actuation.
