Abstract

A method for triggering restraint devices is described in which various algorithms determine values as a function of at least one sensor signal, which are combined to form a measure, and in which the restraint devices are triggered as a function of the measure influenced by at least one signal from a passenger-compartment sensor system.

Claims

1-10. -10. (canceled)

11. A method for triggering a restraint device, comprising:

determining values, in accordance with a plurality of algorithms, as a function of at least one sensor signal from a passenger-compartment sensor system;

combining the values to form a measure influenced by the at least one sensor signal; and

triggering the restraint device as a function of the one measure.

12. The method of claim 11, further comprising determining a triggering time and a type of restraint device as a function of the measure.

13. The method of claim 11, wherein the algorithms use a common measure.

14. The method of claim 13, wherein the measure is a crash severity.

15. The method of claim 14, further comprising ascertaining the crash severity as one of a velocity reduction and a forward displacement.

16. The method of claim 11, further comprising generating the at least one sensor signal via at least one of a pre-crash sensor system and a crash sensor system.

17. The method of claim 11, wherein the plurality of algorithms include at least two of the following algorithms:

a pre-crash algorithm, a frontal algorithm, a side-impact algorithm, an upfront algorithm and a rollover algorithm.

18. The method of claim 14, further comprising using the crash severity one of in a scalar manner, as a vector, and as a matrix.

19. The method of claim 14, wherein the crash severity is specific to one of a used algorithm, a crash type, and the restraint devices.

20. A device for triggering a restraint devices, comprising:

an arrangement to determine values as a function of at least one sensor signal from a passenger-compartment sensor system using a plurality of algorithms;

an arrangement to combine the algorithms to form a measure influenced by the at least one sensor signal; and

an arrangement to trigger the restraint device as a function of the one measure.
