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 unit that is disposed at a predetermined position in said vehicle and measures an impact applied to said vehicle, an impact detection unit that is disposed at a position ahead of said impact measurement unit in said vehicle and outputs a signal based on the observed impact applied to said vehicle at least by a collision, a threshold variation pattern selection unit that selects a working threshold variation pattern, which is used to control activation of said passive vehicle occupant restraint, among a plurality of available threshold variation patterns, based on the output of said impact detection unit; and an activation control unit that compares a specific value calculated from the observed impact by said impact measurement unit with a working threshold value, which varies according to the working threshold variation pattern selected by said threshold variation pattern selection unit, and controls activation of said passive vehicle occupant restraint based on a result of the comparison.
