Abstract
A method of performing passive countermeasures for an automotive vehicle (12) having a vehicle sensor complex (18) generating a vehicle sensor complex signal is provided. The method of performing passive countermeasures includes performing an accelerometer initiated passive countermeasure method and performing a sensor fusion initiated passive countermeasure method. An object is detected with a sensor fusion (14) and an object parameter signal is generated. The object parameter signal is compared with an object parameter threshold level. The sensor fusion initiated passive countermeasure method is terminated when the object parameter signal is greater than the object parameter threshold level.
