Abstract

A safety-relevant system (S) in a vehicle comprises an electrical unit (EE) with at least one signal line input (SE). The signal line input (SE) is connected to a signal line. The electrical unit (EE) additionally comprises a supply connection (VA) for feeding the electrical unit (EE) with electrical energy. For supplying electrical energy to the electrical unit (EE), the signal line is in addition electrically coupled to the supply connection (VA) of the electrical unit (EE).

First claim

The invention claimed is:

1. A safety-relevant system (S) in a vehicle, comprising
an electrical unit (EE) comprising at least one signal line input (SE) which is connected to a signal line, the electrical unit (EE) further comprising a supply connection (VA) for feeding the electrical unit (EE) with electrical energy, the signal line further being electrically coupled to the supply connection (VA) of the electrical unit (EE) for supplying electrical energy to the electrical unit (EE), wherein the supply connection (VA) comprises a positive supply connection and a negative supply connection, and
an emergency supply energy storage device (ES) comprising an energy storage connection (ESA) which is electrically coupled to the positive supply connection or to the negative supply connection for supplying electrical energy to the electrical unit (EE), the emergency supply energy storage device (ES) further being electrically coupled to the signal line for supplying electrical energy to the emergency supply energy storage device (ES).

2. The safety-relevant system (S) according to claim 1 , wherein the emergency supply energy storage device (ES) comprises a super capacitor.

3. The safety-relevant system (S) according to claim 1 , wherein the electrical unit (EE) comprises an electrical actuator.

4. The safety-relevant system (S) according to claim 3 , wherein the electrical actuator is a DC motor.

5. The safety-relevant system (S) according to claim 3 , wherein the signal line is a motor power line.

6. The safety-relevant system (S) according to claim 5 , wherein the signal line is provided for transmitting data.

7. The safety-relevant system (S) according to claim 6 , wherein the electrical unit (EE) comprises a sensor.

8. The safety-relevant system (S) according to claim 1 , wherein the signal line is provided for transmitting data.

9. The safety-relevant system (S) according to claim 8 , wherein the electrical unit (EE) comprises a sensor.

10. The safety-relevant system (S) according to claim 1 , wherein the safety-relevant system (S) is an electrical door lock system of the vehicle.

11. The safety-relevant system (S) in a vehicle, comprising
an electrical unit (EE) comprising at least one signal line input (SE) which is connected to a signal line, the electrical unit (EE) further comprising a supply connection (VA) for feeding the electrical unit (EE) with electrical energy,
an emergency supply energy storage device (ES) comprising an energy storage connection (ESA) which is electrically coupled to the supply connection (VA) of the electrical unit (EE) for supplying electrical energy to the electrical unit (EE), the emergency supply energy storage device (ES) further being electrically coupled to the signal line for supplying electrical energy to the emergency supply energy storage device (ES).

12. The safety-relevant system (S) according to claim 11 , wherein the emergency supply energy storage device (ES) comprises a super capacitor.

13. The safety-relevant system (S) according to claim 11 , wherein the electrical unit (EE) comprises an electrical actuator.

14. The safety-relevant system (S) according to claim 13 , wherein the electrical actuator is a DC motor.

15. The safety-relevant system (S) according to claim 13 , wherein the signal line is a motor power line.

16. The safety-relevant system (S) according to claim 15 , wherein the signal line is provided for transmitting data.

17. The safety-relevant system (S) according to claim 16 , wherein the electrical unit (EE) comprises a sensor.

18. The safety-relevant system (S) according to claim 11 , wherein the safety-relevant system (S) is an electrical door lock system of the vehicle.

19. The safety-relevant system (S) according to claim 11 , wherein the signal line is provided for transmitting data.

20. The safety-relevant system (S) according to claim 19 , wherein the electrical unit (EE) comprises a sensor.
