1. A vehicle collision decision apparatus comprising:

  • an acceleration measuring device for measuring an acceleration which acts on a vehicle and generating an acceleration signal;

    an occupant movement characteristics calculating device for calculating occupant movement characteristics according to an acceleration signal which is measured by the acceleration measuring device;

    an occupant movement characteristics determining device for determining whether or not the occupant movement characteristics exceed a predetermined movement characteristics determining threshold;

    a frequency analyzing device for decomposing waveforms of the acceleration signal which are measured by the acceleration measuring device into frequency components;

    a frequency component determining threshold setting device for setting a predetermined frequency component determining threshold for the frequency component according to results by the occupant movement characteristics determining device;

    a frequency component determining device for determining whether or not the frequency component exceeds the frequency component determining threshold;

    a control signal generating device for generating a control signal for controlling an occupant-protecting apparatus according to results by the frequency component determining device.
