Abstract
In a method for triggering a passenger protection arrangement for a vehicle, a crash type is detected with the aid of at least one structure-borne noise signal, and the triggering takes place as a function of the crash type. For the crash type recognition, the structure-borne noise signal is evaluated in a predefined time period with regard to a change in amplitude.

1-10. (canceled)
A method for triggering a passenger protection arrangement for a vehicle, comprising:
- ascertaining a crash type with the aid of at least one structure-borne noise signal, wherein for the crash type ascertainment the structure-borne noise signal is evaluated in a predefined time period with regard to a change in amplitude;
- and
- triggering the passenger protection arrangement as a function of the ascertained crash type.
A control device for triggering a passenger protection arrangement for a vehicle, comprising:
- an interface configured to provide at least one structure-borne noise signal;
- an evaluation circuit having a crash-type determination module and a triggering module, wherein the crash-type determination module is configured to determine a crash type as a function of at least one structure-borne noise signal, the crash-type determination module having an analysis module for evaluation of a change in amplitude in a predefined time period, and wherein the triggering module is configured to generate a triggering signal as a function of the determined crash type;
- and
- a triggering circuit for triggering the passenger protection arrangement as a function of the triggering signal.
