    摘要： 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.

    摘要： A method and device for controlling the triggering of passive safety systems, such as airbags in vehicles, in response to criteria being detected that are to be interpreted as the existence of a dangerous impact. One of these criteria is the impact speed. A measure of the impact speed is ascertained in that first the instant of the impact onset of the vehicle against an obstacle is detected and then the instant is detected when the acceleration of the rigid support structure of the vehicle transitions from light to heavy acceleration. The time difference between the impact-onset instant and the acceleration-transition instant is a measure of the impact speed. To ascertain the instants, integral values of acceleration signals from acceleration sensors may be utilized and analyzed in an appropriate manner. The method and device are applicable, in particular, in the discrimination of impact processes at low driving speeds.

    摘要： A clear distinction between deployment and nondeployment situations is made by subjecting the measured acceleration of a vehicle to low-pass filtration, forming a deployment threshold as a function of the filtered acceleration signal, analyzing an acceleration signal, as soon as it is measured, in a first time segment to determine characteristic features indicating a crash event in which the restraint device should not be deployed and reducing the cut-off frequency of the low-pass filter for a predetermined time segment if a nondeployment situation of this type is detected.
