Appeal No. 2001-2393
Application No. 09/197,878
1. In a vehicular supplemental restraint system
having a sensor providing a vehicle acceleration
signal, a restraint device and a controller for
deploying the restraint device for vehicle occupant
protection in a crash event when a filtered version
of the acceleration signal exceeds a deployment
threshold, the improvement wherein the controller:
initializes the deployment threshold at a
default level prior to the crash event;
determines an event progression signal during
the crash event based on the acceleration signal to
detect predefined progression levels of the crash
event;
determines a slope of the filtered acceleration
signal;
periodically adjusts the deployment threshold
based on the determined slope, provided that the
filtered acceleration signal is within an adjustment
range specified for the detected progression level
of the crash event.
