Abstract
A collision type identifying device is disposed in a central portion of a vehicle main body and has first deceleration detecting device (), peak time detecting device (), required time detecting device (), and type identifying device (). The deceleration detecting device () detects a vehicle deceleration in the longitudinal direction. The peak time detecting device () detects, as a first peak time (tp), a time from the excess of a preset threshold (GTH) by a waveform of the vehicle deceleration (G) detected by the deceleration detecting device () to a first peak. The required time detecting device () detects, as a required time (tn), a time when an integrated deceleration (VG) obtained through time quadrature of the vehicle deceleration (G) becomes equal to a predetermined integrated value set in advance. The type identifying device () identifies a vehicle collision type on the basis of the first peak time (tp) and the required time (tn). The collision type identifying device can identify a vehicle collision as one of a plurality of collision types at once.
