Method and apparatus for sensing a vehicle crash using crash energy

摘要

A method and apparatus is disclosed for providing a passenger restraint actuation signal for use in an actuatable passenger restraint system in a vehicle is provided. A sensor provides a signal indicative of crash acceleration. A crash energy value is determined from the crash acceleration signal and is compared against an energy threshold value. If the determined crash energy value equals or exceeds the energy threshold value, a passenger restraint actuation signal is provided.
