20080269991 | Activation-Control Device for Occupant Crash-Protection Apparatus - A colliding-initial detecting section detects colliding-initial timing at which an impact level detected by an acceleration sensor in the inside of a vehicle reaches a predetermined threshold, and when the colliding-initial timing is detected, a one-shot timer is set. Meanwhile, an impact-judging section detects strong-impact occurrence timing at which the impact level detected by an acceleration sensor on the front reaches a predetermined threshold. When the strong-impact occurrence timing is within a time set by the one-shot timer from the colliding-initial timing, an And circuit outputs an activating signal activating an air bag to a driving section. | 10-30-2008 |
