Abstract
A method and a control device for triggering passenger protection devices are provided, the passenger protection devices being triggered as a function of a first acceleration signal and/or a driving dynamics signal. The acceleration signal is corrected by an offset by a comparison with the driving dynamics signal.
Claims16
A control device for triggering a passenger protection device, comprising:
- a first interface adapted to provide at least one first acceleration signal of an airbag acceleration sensor system;
- a second interface adapted to provide at least one driving dynamics signal of a driving dynamics system that is separate from the airbag acceleration sensor system;
- an evaluation circuit adapted to trigger the passenger protection device as a function of at least one of the at least one first acceleration signal and the at least one driving dynamics signal;
- and
- an offset correction circuit adapted to correct the at least one first acceleration signal by an offset that is obtained by calculating a difference between the at least one driving dynamics signal and one of the at least one first acceleration signal and a value calculated from the at least one first acceleration signal.

A method for triggering a passenger protection device, comprising:
- triggering the passenger protection device as a function of at least one of:
- i) at least one first acceleration signal, and ii) at least one driving dynamics signal of a driving dynamics system that is separate from a sensor system that generates the at least one first acceleration signal;
- and
- correcting the at least one first acceleration signal by an offset that is obtained by calculating a difference between the at least one driving dynamics signal and one of the at least one first acceleration signal and a value calculated from the at least one first acceleration signal.
