1. A device for detecting a collision of a vehicle based on a collision acceleration of the vehicle detected by an acceleration detecting means, said device comprising:
- a collision force calculating means for calculating an estimated collision force based on the collision acceleration, an estimated velocity of the vehicle, calculated from the collision acceleration, and an estimated displacement of the vehicle, calculated from the estimated velocity; and
a collision determining means for discriminating a collision based on the estimated collision force.
