Abstract:
Apparatus for controlling deployment of an occupant restraint in a motor vehicle crash, the apparatus comprising:means for receiving and sampling an acceleration signal; means for deriving a first oscillation value from consecutive values of the received and sampled acceleration signal in a first predetermined process; means for deriving a second oscillation value from the consecutive values of the received and sampled acceleration signal in a second predetermined process; means for activating a predetermined one of the means for deriving a first oscillation value and the means for deriving a second oscillation value on the basis of a reference datum so that a selected one of the first oscillation value and the second oscillation value is derived; and means for deriving an occupant restraint deployment signal from the received and sampled acceleration signal and the selected one of the first oscillation value and the second oscillation value.
