Abstract
To provide a collision detecting apparatus for a vehicle, including an integrating member for cumulatively integrating an output from an acceleration sensor when the output exceeds a specific calculation start level and a collision detecting member for outputting a collision signal when a cumulative integral value calculated by the integrating member exceeds a threshold value, wherein the collision detecting apparatus is intended to accurately perform a collision decision by preventing the occurrence of an 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 member W for detecting that an output waveform from the acceleration sensor S is a specific periodical vibration waveform, and a correcting member H for correcting the threshold value &agr; 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.
