Abstract:
A collision detecting apparatus for a vehicle comprising:an acceleration sensor (S) for detecting an acceleration upon collision of said vehicle; integrating means (I) for cumulatively integrating an output (G) from said acceleration sensor (S) when the output (G) exceeds a specific calculation start level (G0); and collision detecting means (C) for outputting a collision signal (X) when a cumulative integral value (&Sgr;G) calculated by said integrating means (I) exceeds a threshold value (&agr;); vibration waveform detecting means (W) for detecting that an output waveform from said acceleration sensor (S) is a specific periodical vibration waveform; and correcting means (H) for correcting the threshold value (&agr;) on the basis of detection of the vibration waveform by said vibration waveform detecting means (W) so as to lower a detecting sensitivity of said collision detecting means (C).
