Abstract:
1. An airbag control apparatus comprising: an acceleration detector for detecting acceleration in a longitudinal direction and lateral direction of a vehicle; a collision decision section configured to make a decision about a frontal collision and side-impact collision of the vehicle in accordance with detection outputs of said acceleration detector; and a driver for inflating front airbags for protecting occupants from the frontal collision and side airbags for protecting the occupants from the side-impact collision, in response to a decision output of said collision decision section, wherein said collision decision section suppresses the decision about the side-impact collision in accordance with collision information, about the frontal collision in the longitudinal direction of the vehicle, which collision information is included in the detection outputs of said acceleration detector, and an ECU makes a comparison of a derived magnitude of a frontal collision to a threshold magnitude value to generate a feedback communication through a level adjusting means, prior to determining an activation of the collision driver for inflating at least one side air bag, the comparison by the ECU allows for flexible logic circuit implementation with the detection of a collision other than the side impact collision by using the frontal collision decision as a trigger of the decision for suppression of the collision process.
