To provide a collision detecting apparatus for a vehicle, including an integrating apparatus for cumulatively integrating an output from the acceleration sensor when the output exceeds a specific calculation start level, and a collision detecting apparatus for outputting a collision signal when a cumulative integral value calculated by the integrating apparatus exceeds a threshold value. The collision detecting apparatus is intended to accurately perform a collision decision with a high responsiveness irrespective of the severeness of the collision. The collision detecting apparatus includes a differentiating apparatus D for differentiating the output G from the acceleration sensor S, and a correcting apparatus H for correcting the threshold value α on the basis of a differential value (dG/dt) calculated by the differentiating apparatus D.
A collision detecting apparatus for a vehicle comprising:
A method of detecting a collision of a vehicle comprising the following steps:
The method of detecting a collision of a vehicle according to claim wherein in a rigid collision of a vehicle the cumulative integral value ΣG exceeds the threshold value α−dG/dt with a second predetermined timing for providing an optimal control for actuating an air bag.
