ABSTRACT:
An airbag trigger control system is provided with a first sensor which is disposed in a predetermined position in a vehicle body and outputs a signal corresponding to an impact exerted to the vehicle body, a trigger control system which triggers an airbag when a parameter determined on the basis of the signal output from the first sensor exceeds a predetermined threshold value, a second sensor which is disposed forward of the first sensor in the vehicle body and outputs a signal corresponding to an impact exerted to the vehicle body, and a threshold value changing device which changes the predetermined threshold value in accordance with the signal output by the second sensor. The second sensor outputs a predetermined signal at predetermined intervals, and the threshold value changing device changes the predetermined threshold value to a given value when the output signal of the second sensor is not detected in a predetermined number of successive control cycles.
