Abstract
A sensor (22) senses crash acceleration and provides a crash acceleration signal indicative thereof. A processor (54) sums the crash acceleration signal with an occupant spring-mass model (56, 60) so as to provide an adjusted or "virtual" crash acceleration signal (64) more nearly representative of the actual acceleration of the vehicle occupant during a crash event. A discriminating circuit (70, 76, 80, 82, 90, 92, 84, 100, 104, 108, and 96) controls the actuatable restraining device (28) in response to the adjusted crash acceleration signal (64).
