Abstract
A vehicle collision decision apparatus determines whether or not an occupant-protecting apparatus should be started in a collision by an occupant moving characteristics determining device. Also, whether or not the collision continues is determined in an acceleration change determining section. A determining threshold for a frequency component which indicates damage to the vehicle which is calculated in a frequency component calculating device is selected. The occupant-protecting apparatus is activated appropriately by monitoring the damage to the vehicle in the frequency component determining device by using the frequency component. By doing this, a vehicle collision decision apparatus which can determine the condition in the vehicle collision appropriately is provided.
