Abstract

A control device and a method for triggering personal protection arrangement for a vehicle are provided, an energy reserve supplying electrical energy for the triggering. A control circuit is provided, which, as a function of the personal protection arrangement to be triggered, forms from the electrical energy at least one individual firing pulse for triggering the individual personal protection arrangement, with respect to a first firing pulse amplitude and a first firing pulse duration.

Claims

1-10. -10. (canceled)

11. A control device for triggering a personal protection arrangement for a vehicle, comprising:

an energy reserve, which provides electrical energy for the triggering;

wherein the energy reserve has a control circuit, which, as a function of the personal protection arrangement to be triggered, forms from the electrical energy at least one individual firing pulse for the triggering of the individual personal protection arrangement with regard to a first firing pulse amplitude and a first firing pulse duration.

12. The control device of claim 11, wherein, in a first time interval, the control circuit specifies the at least one firing pulse at a second firing pulse amplitude and a second firing pulse duration, and in a second time interval following the first time interval, at a third firing pulse amplitude and a third firing pulse duration, the second firing pulse amplitude being greater than the third firing pulse amplitude, and a third firing pulse duration, the second firing pulse amplitude being greater than the third firing pulse amplitude and the second firing pulse duration being shorter than the third firing pulse duration, and the first time interval is used for triggering a first personal protection arrangement, and the second time interval for triggering a second personal protection arrangement.

13. The control device of claim 12, wherein the control circuit has data that specify the first and the second time duration.

14. The control device of claim 13, wherein the data assign the first time interval to the first personal protection arrangement and the second time interval to the second personal protection arrangement.

15. The control device of claim 14, wherein the data are permanently stored or are generated as a function of a triggering decision.

16. A method for triggering a first personal protection arrangement for a vehicle, the method comprising:

providing an energy reserve for providing electrical energy for the triggering; and

as a function of the personal protection arrangement to be triggered, forming, using a control circuit, from the electrical energy at least one individual firing pulse for the triggering of the individual personal protection arrangement, with regard to a first firing pulse amplitude and a first firing pulse duration.

17. The method of claim 16, wherein the control circuit specifies the at least one firing pulse in a first time interval at a second firing pulse amplitude and a second firing pulse duration, and in a second time interval following the first time interval, at a third firing pulse amplitude and a third firing pulse duration, the second firing pulse amplitude being greater than the third firing pulse amplitude, and the second firing pulse duration being shorter than the third firing pulse duration, the first time interval being used to control first personal protection arrangement, and the second time interval being used to control second personal protection arrangement.

18. The method of claim 17, wherein the first and the second time interval are specified by arrangement of data.

19. The method of claim 18, wherein the data assign the first time interval to the first personal protection arrangement, and the second time interval to the second personal protection arrangement.

20. The method of claim 16, wherein the data are permanently stored or are generated as a function of a triggering decision.
