An apparatus is provided for detecting a vehicle crash condition and providing a signal indicative of such a crash condition. The apparatus includes a controller (46) that determines crash velocity and crash displacement signal in response to sensed crash acceleration. The controller (46) has a plurality of deployment criteria zones each defined by an associated range of crash velocity values and crash displacement values. Each of the plurality of deployment criteria zones has at least one associated crash metric. The controller (46) selects one of the plurality of deployment criteria zones in response to both the crash velocity value and the crash displacement value. The controller (46) further determines whether a crash metric of the selected deployment criteria zone indicates that a deployment crash condition is occurring. The controller (46) provides a deployment signal in response to the crash metric indicating a deployment crash condition is occurring. |
