Abstract

A starting apparatus for a passenger protecting apparatus includes a collision deciding unit, a control unit, and a trigger. The collision deciding unit makes a collision decision depending upon output of an acceleration sensor which detects acceleration at a time of collision. The control unit controls generation of a starting signal based upon a difference between output of a decelerating direction integrating unit, which integrates the acceleration signal of the acceleration sensor in the decelerating direction, and output of accelerating direction integrating unit, which integrates the acceleration signal of the acceleration sensor in an acceleration direction. The trigger outputs the starting signal based on output of the collision deciding unit and output of the control unit.

Dependent claims

A starting apparatus to start a passenger protecting apparatus for protecting a passenger in a movable body, comprising:

an acceleration sensor to detect and output acceleration of said movable body;
collision deciding means for deciding whether or not collision occurs depending upon the acceleration detected by said acceleration sensor;
decelerating direction integrating means for integrating the output of said acceleration sensor in a decelerating direction;
acceleration direction integrating means for integrating the output of said acceleration sensor in an accelerating direction;
control means for determining a difference between output from said decelerating direction integrating means and output from said accelerating direction integrating means;
and
trigger means for outputting a starting signal of said passenger protecting apparatus based on output of said collision deciding means and output of said control means.
