Patent ID: 7587266

Claim:
A device for determining a collision object of a vehicle, the device comprising: setting means for setting a determination amount on a basis of at least one of an acceleration of a deformable member which is deformed due to an impact at a time of vehicle collision and a frequency component of the acceleration; correcting means for correcting the determination amount by removing an effect of acceleration of a vehicle body; and determining means for determining an object collided with the deformable member on the basis of the determination amount corrected by the correcting means, wherein the determination amount comprises a deforming speed of the deformable member, and wherein, the determining means comprises: deformation amount calculating means for calculating an amount of initial deformation from a reference value of the deforming speed on the basis of the deforming speed corrected by the correcting means, the reference value being previously set at a collided portion of the deformable member; return amount calculating means for calculating a return amount of deformation after being initially deformed as a return amount of deformation, on the basis of the deforming speed corrected by the correcting means; and collision object determining means for determining the object collided with the collision part according to the amount of deformation and the return amount of deformation.
