ABSTRACT:
A crash mode determining unit comprises first and second acceleration sensors disposed on both sides of a vehicle and a third acceleration sensor disposed almost at a center of the vehicle. A relative line integration length of one of the integrated outputs of the accelerations detected by the first and second acceleration sensors with respect to the integrated output of the acceleration detected by the third acceleration sensor is calculated. The relative line integration length of the integrated output becomes long when a crash mode is either a pole crash or a under-ride crash. Therefore, the crash mode of the pole crash or the under-ride crash can be determined by comparing the relative line integration length with a predetermined length.
