Abstract

A trigger procedure for a restraint system for protection of the occupants in a vehicle, where short-time spectral analyses of at least one acceleration component of the vehicle structure are continuously implemented and at least one parameter characteristic for the deformation of the vehicle structure (trigger parameter) is calculated from several spectral components. The calculated trigger parameters are compared with one or more preset threshold values to make a decision on triggering of the restraint system.
