1. A method for controlling an actuatable restraining device comprising the steps of:
- sensing a plurality of crash event indications;
classifying crash events in response to comparing the sensed crash event indications against one another to identify at least one of a forward rigid barrier crash event, an offset deformable barrier crash event, an angular crash event, and a small overlap crash event; and
controlling deployment timing of the actuatable restraining device in response to the classification of the crash event.
