Abstract

A sensor system for an electric/electronic architecture in a vehicle, having at least one sensor module for capturing at least one physical variable and at least one first interface for communication with a first bus system, and to an associated electric/electronic architecture for a vehicle. At least one second interface for communication with a second bus system is present, data of the at least one sensor module being able to be output via both bus systems.

Claims

1. A sensor system for an electronic architecture in a vehicle, comprising:

at least one sensor module for capturing at least one physical variable;

at least one first interface of the sensor system connected to the at least one sensor module and to a first bus system for communication with the first bus system; and

at least one second interface of the sensor system connected to the at least one sensor module and to a second bus system for communication with the second bus system, wherein data of the at least one sensor module is able to be output via the first and second bus systems, wherein the data of the at least one sensor module is not routed via a control unit when output via the first and second bus systems.

2. The sensor system as recited in claim 1, wherein the at least one sensor module includes a first sensor module and a second sensor module for capturing the at least one physical variable.

3. The sensor system as recited in claim 2, wherein data of the first sensor module are able to be evaluated for a plausibility check of data of the second sensor module based on a comparison of the data of the first and second sensor modules, and wherein the data of the second sensor module are able to be evaluated for a plausibility check of the data of the first sensor module based on a comparison of the data of the first and second sensor modules.

4. The sensor system as recited in claim 2, wherein a supply line supplies the first interface, the first sensor module, and a voltage regulator with energy.

5. The sensor system as recited in claim 4, wherein the voltage regulator supplies the second interface and the second sensor module with energy.

6. The sensor system as recited in claim 1, wherein the first bus system includes a PSI5 bus system, and wherein the second bus system includes a CAN bus system.

7. The sensor system as recited in claim 6, wherein a line of the first bus system includes a supply line.

11. The sensor system as recited in claim 1, wherein:

the first sensor module includes a first signal line connection to the first interface,

the second sensor module includes a first signal line connection to the second interface and a second signal, and

the first sensor module and the second sensor module share a second signal line connection that connects the first and second sensor modules to each other.

8. An electronic architecture for a vehicle, comprising:

a first control unit;

a second control unit; and

a sensor system, the first and second control units communicating with the sensor system via at least one bus system, wherein the sensor system includes;

at least one sensor module for capturing at least one physical variable,

at least one first interface of the sensor system connected to the at least one sensor module and to a first bus system for communication with the first bus system, and

at least one second interface of the sensor system connected to the at least one sensor module and to a second bus system for communication with the second bus system, wherein data of the at least one sensor module is able to be output via the first and second bus systems, wherein the data of the at least one sensor module is not routed via a control unit when output via the first and second bus systems.

9. The electronic architecture as recited in claim 8, wherein the first control unit communicates with the sensor system via the first bus system, and wherein the second control unit communicates with the sensor system via the second bus system.

10. The electronic architecture as recited in claim 9, wherein the first control unit includes an air bag control unit, and wherein the second control unit includes an electronic stability program control unit.

12. The electronic architecture as recited in claim 8, wherein:

the first sensor module includes a first signal line connection to the first interface,

the second sensor module includes a first signal line connection to the second interface and a second signal, and

the first sensor module and the second sensor module share a second signal line connection that connects the first and second sensor modules to each other.
