1. A vehicle collision decision apparatus comprising:

  • an acceleration measuring device which measures an acceleration of a vehicle and generates an acceleration signal;

    an occupant movement characteristics calculating device which calculates occupant movement characteristics according to the acceleration signal from the acceleration measuring device;

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

    a frequency analyzing device which decomposes a waveform of the acceleration signal into a frequency component;

    a frequency component determining threshold setting device which sets 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 which determines whether or not the frequency component exceeds the frequency component determining threshold; and

    a control signal generating device which generates a control signal that controls an occupant-protecting apparatus according to results by the frequency component determining device.
