Abstract
A trigger device for a vehicle safety apparatus includes an acceleration sensor for detecting an acceleration of a vehicle and generating an electric acceleration signal representative thereof, an integration section for integrating the acceleration signal during each given integration period and generating an integration value representative of a result of the integrating, a determination section for determining whether or not a collision of the vehicle is present on the basis of the integration value generated by the integration section, and a trigger section for triggering the vehicle safety apparatus when the determination section determines a collision of the vehicle to be present. The determination section includes a differentiator for detecting a differential value of the acceleration signal which occurs at a given moment in the integration period, an adder for adding the differential value detected by the differentiator and the integration value generated by the integration section, and for generating an addition value representative of a result of the adding, and a sub-determination section for determining whether or not a collision of the vehicle is present on the basis of the addition value generated by the adder.
