Abstract: A method for triggering a restraining device in a motor vehicle is proposed, where a crash severity and an occupant categorization are implemented independently of each other. By linking the crash severity with the occupant categorization, the restraining device required for the vehicle occupants is triggered. The crash severity is subdivided in accordance with the triggering events frontal impact, side impact, rear impact or vehicle roll-over. A decisive advantage is that the crash severity is implemented independently of the occupant categorization.

Abstract: A system for sensing a head-on collision in a vehicle, where at least one upfront sensor is used as plausibility sensor, which provides a plausibility signal for a collision sensor located in the control device. The upfront sensor may be an acceleration sensor, which analyzes both the acceleration signal as well as the speed signal derived therefrom for a plausibility check. The results of this check are linked in an OR-operation in order to generate a plausibility signal. In an example embodiment, it is provided to buffer-store the plausibility signal in the control device for a predetermined time. This is of special interest for improved reliability in the event that the upfront sensor has been destroyed.

Abstract: A restraint system having a restraint device for protecting at least one passenger and a method for controlling a restraint system. The system and method act so as to 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.
