Abstract

In the case of a process for deactivating pyrotechnic actuators in vehicles, the actuators are triggered jointly if a code signal provided for this purpose and stored in the vehicle is fed from the outside. The two code signals are checked with respect to their conformity.

Claims

1. Process for deactivating pyrotechnic actuators in a vehicle, the process comprising the acts of:

storing a code signal in the vehicle for triggering the actuators; and

jointly triggering the actuators if an exteriorly fed code signal conforms to the code signal stored in the vehicle.

2. Process according to claim 1, wherein the act of jointly triggering the actuators triggers the actuators simultaneously.

3. Process according to claim 1, wherein the act of jointly triggering the actuators triggers the actuators successively at a defined time interval.

4. Process according to claim 1, further comprising the act of, for preparing a triggering operation, electro-mechanically manipulating an on-board power supply.

5. Process according to claim 2, further comprising the act of, for preparing a triggering operation, electro-mechanically manipulating an on-board power supply.

6. Process according to claim 3, further comprising the act of, for preparing a triggering operation, electro-mechanically manipulating an on-board power supply.

7. Process according to claim 1, wherein the code signal stored in the vehicle.

8. Process according to claim 2, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code.

9. Process according to claim 3, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code.

10. Process according to claim 4, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code.

11. Process according to claim 1, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code vehicle-individual signal and is centrally stored.

12. Process according to claim 2, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code vehicle-individual signal and is centrally stored.

13. Process according to claim 3, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code vehicle-individual signal and is centrally stored in an external memory.

14. Process according to claim 4, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code vehicle-individual signal and is centrally stored in an external memory.

15. Process according to claim 7, wherein the code signal stored in the vehicle is stored as a non-readable, non-overwritable code vehicle-individual signal and is centrally stored in an external memory.

16. Process according to claim 11, wherein the code signal stored in the external memory is stored as a signed accessible only to authorized persons.

17. Process according to claim 16, wherein identities of said authorized persons are stored when the stored code signal is supplied.
