child restraint with a restraint system for protecting at least one passenger, and methods for controlling a withdrawal scheme

摘要

A restraint system having a restraint device for protecting at least one passenger and a method for controlling a restraint system are proposed, which act so as to transform using a wavelet transformation, a signal measured by an acceleration sensor into a frequency range and in order to determine from the transformed signal the optimal triggering time point for the restraint device. For this purpose, the wavelet-transformed signal, on the one hand, is used for determining features in order to determine a crash type, and, on the other hand, to determine the braking acceleration energy. If the braking acceleration energy lies above a preestablished threshold value and if the identified crash type requires a triggering of the restraint system, then the restraint system is triggered.
