Patent ID: 6944525

Claim:
An airbag apparatus activation control apparatus comprising: a first sensor that is disposed at a predetermined position in a vehicle and that outputs a signal corresponding to an impact that occurs on the vehicle; activation control means for activating an airbag apparatus if a parameter value based on the signal outputted by the first sensor exceeds a predetermined threshold; a plurality of second sensors each of which is disposed at a position in the vehicle that is different from a position of the first sensor and each of which outputs a signal corresponding to an impact that occurs on a site in the vehicle related to the sensor; and threshold changing means for changing the predetermined threshold in accordance with signals outputted by the plurality of said second sensors on the basis of a threshold reduction map, wherein the threshold changing means sets a failsafe predetermined value, if at least one of the plurality of second sensors has a failure, and sets the predetermined threshold to the failsafe predetermined value when the predetermined threshold based on the signal from the at least one second sensor that does not have a failure is greater than the failsafe predetermined value.
