ABSTRACT:
A two-step deployment control method for a supplemental inflatable restraint (SIR) in a vehicle. The deployment decision includes a "time to wait" step in which the control determines "when to deploy", and a "severity" step in which the control determines "whether to deploy". The "time to wait" step is based on an estimation of occupant displacement due to the crash, and the "severity" step is based on an estimation of the crash severity. The control method is modified to initiate earlier deployment when the acceleration data is indicative of a localized impact which does not involve the full front structure of the vehicle, such as an angle or pole impact.
