Abstract
An improved deployment method for a vehicular supplemental restraint system having an acceleration sensor and a restraint device to be deployed for occupant protection in a crash event, where the deployment is initiated when a filtered version of the acceleration signal exceeds a deployment threshold that is periodically adjusted based on one or more secondary measures of crash severity, including a vehicle speed measurement at the onset of the crash event, and the level of event progression. In a first embodiment, the vehicle speed measurement pertains to the ground or absolute speed of the vehicle at the onset of the crash event; in a second embodiment, the vehicle speed measure pertains to the vehicle speed relative to a detected obstacle at the onset of the crash event.
