  "textContent": "The invention provides a collision detecting apparatus for a vehicle, including an integrating means for cumulatively integrating an output from an acceleration sensor when the output exceeds a specific calculation start level, and a collision detecting means for outputting a collision signal when a cumulative integral value calculated by the integrating means exceeds a threshold value, wherein the collision detecting apparatus is intended to accurately perform collision decision by preventing the occurrence of erroneous detection based on a vibration waveform of acceleration of the vehicle due to, for example, riding past a stepped portion. The collision detecting apparatus includes a vibration waveform detecting means(W) for detecting that an output waveform from the acceleration sensor(s) is a specific periodical vibration waveform, and a correcting means(H) for correcting the threshold value( alpha ) on the basis of detection of the vibration waveform by the vibration waveform detecting means(W) so as to lower a detecting sensitivity of the collision detecting means (C).",
