COLLISION TYPE IDENTIFYING DEVICE

A collision type identifying device is disposed in a central portion of a vehicle main body and has first deceleration detecting device ( 22 ), peak time detecting device ( 32 ), required time detecting device ( 34 ), and type identifying device ( 36 ). The deceleration detecting device ( 22 ) detects a vehicle deceleration in the longitudinal direction. The peak time detecting device ( 32 ) 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 ( 22 ) to a first peak. The required time detecting device ( 34 ) 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 ( 36; 78 ) 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.
