Abstract:
An activation control apparatus of an airbag apparatus, comprising:a first sensor that is disposed at a predetermined position in a vehicle body and that outputs a signal corresponding to an impact that occurs on a vehicle; an activation control means for activating the airbag apparatus if a parameter based on the signal outputted by the first sensor exceeds a predetermined threshold; a second sensor that is disposed forward of the predetermined position of the first sensor within the vehicle body and that outputs a signal corresponding to an impact that occurs on the vehicle; threshold setting means for setting one value of at least three values as the predetermined threshold based on the signal outputted by the second sensor; and threshold switching means for, if the one value of the at least three values has been set as the predetermined threshold by the threshold setting means, switching the predetermined threshold to another value of the at least three values, wherein the threshold switching means switches to the another value after the second sensor continues for a predetermined time to output a signal for which the threshold setting means sets the predetermined threshold to the another value, and further wherein the predetermined time is based on a difference between the one value and the another value.
