Embodiment Construction

[0037] exist figure 1 A circuit block diagram of the first embodiment of the present invention is shown in . The control device SG according to the invention is explained in detail with the aid of this block diagram. A control unit SG is accommodated in the vehicle FZ, said control unit SG being connected to various components. Only those external and internal components of the control device that are necessary for understanding the invention are shown here by way of example.

[0038] Various accident sensors, such as a structure-borne sound sensor KS, an acceleration sensor BS1, a pressure sensor DS, and an environment sensor US, are connected to the control device SG. Further sensors, such as driving dynamics sensors and / or rotational speed sensors, etc., can be connected in addition to or instead of the aforementioned sensors. Various installation positions in this vehicle FZ are known to the skilled person. The structure-borne sound sensor system KS and the acceleratio...

Abstract

A method is proposed for activating at least one security means (FDR, PS1), which comprises a first step of acquiring at least two features (M1, M2, M3) from at least one signal of an accident sensor system, in order to calculate a feature vector from the acquired features (M1, M2, M3). Subsequently, in a second method step, a classification of the calculated feature vector is performed with the aid of a classifier (MSVM) on the basis of the statistical learning theory, in order to classify the feature vector in one of at least three possible feature classes (K1, K2, K3). An activation of the security means (PS1, FDR1) according to an activation guidelines (T1, FLIC1, T2, T2, FLIC2) for the feature class (K1, K2, K3) in which the feature vector was classified is provided as a third method step.

Description

technical field [0001] The invention relates to a method for activating at least one safety device according to claim 1 , a control device for activating at least one safety device according to claim 10 , a computer according to claim 11 program, and a computer program product according to claim 12. Background technique [0002] Existing triggering algorithms for personal protection devices such as airbags do not analyze the movement history of the vehicle, or do so only imprecisely, in order to carry out an optimized triggering of the safety device. In the existing system, the triggering decision is mainly obtained based on the acceleration signal that occurs in an accident and is measured by the acceleration sensor. Predictive systems, such as "pre-crash", try to pre-condition the triggering algorithms, for example by means of radar or laser sensors. However, these signals have not yet been combined with the information of other sensors installed in the vehicle, or have ...
