Abstract
An analog signal processing system and decision logic for controlling airbag deployment includes low pass filter circuitry, differentiation circuitry and integration circuitry operable to receive an analog acceleration signal and provide a differentiated analog bandpass acceleration signal, a reduced bandpass analog acceleration signal, a low pass analog acceleration signal, an analog velocity signal and an analog displacement signal. An interface circuit receives the foregoing analog signals and converts such signals to a number of logic level signals based on comparison with a number of predefined analog threshold signals. A decision logic circuit receives the converted logic level signals and processes such signals to discriminate between severe and non-severe impact events, and control airbag deployment in accordance therewith.
