摘要：A crash detection apparatus of a vehicle includes acceleration sensors mountedon different positions of a vehicle, each for detecting an acceleration at its position. Acrash mode identifying section identifies a crash mode of the vehicle in accordance with atime difference between timings at which integral values obtained by integrating theindividual acceleration signals supplied from the acceleration detectors exceed athreshold value. In accordance with the crash mode, a reference threshold value of acomparator for making a crash decision is determined. This makes it possible to

implement a crash detection apparatus of a vehicle capable of making a responsive crashdecision even in an asymmetric crash in which only one side of the vehicle is deformed andthe occurrence of a large acceleration signal is delayed.
