Zusammenfassung:A vehicle crash sensing system and method are provided for sensing a vehicle crash event. The system includes a linear acceleration sensor located on a vehicle for sensing linear acceleration along a first sensing axis and generating a linear acceleration signal. The system has linear crash sensing logic for determining a crash event along the first sensing axis as a function of the sensed linear acceleration. The system also has signal processing circuitry for processing the linear acceleration signal and generating a processed linear acceleration signal. The system has an angular rate sensor located on the vehicle for sensing an angular roll rate of the vehicle about a second sensing axis and generating a roll rate signal. The system further includes rollover crash sensing logic for determining a rollover event of the vehicle about the second sensing axis as a function of the processed linear acceleration signal and the roll rate signal.
