Abstract:
An activation control apparatus for controlling activation of a passive vehicle occupant restraint mounted on a vehicle, said activation control apparatus comprising:an impact measurement sensor disposed at a predetermined position in said vehicle which measures an impact applied to said vehicle;an activation controller which compares a value calculated from the measurement of the impact by said impact measurement sensor with a threshold value that varies according to a specified threshold variation pattern, and controls activation of said passive vehicle occupant restraint based on the result of comparison;an impact detector disposed at a position ahead of said impact measurement sensor in said vehicle which determines whether or not the impact applied to said vehicle is not less than a specified reference value; anda threshold variation pattern changer which changes said specified threshold variation pattern to another threshold variation pattern when said impact detector determines that the impact applied to said vehicle is not less than said specified reference value.
