Abstract

A system for data processing and storage in vehicles having a zone-based, central computing in-vehicle communications network architecture, includes a zone control unit (ZCU) that receives electronic messages from one or more sensors or electronic control units (ECUs) located within a zone of the vehicle, the ZCU comprising a protocol data unit (PDU) gating module that converts the electronic messages into a plurality of PDUs, and a switch-based Ethernet network that transmits the plurality of PDUs, using Ethernet protocol frames comprising the plurality of PDUs, to a central computing platform. The central computing platform includes an Ethernet handler module that decomposes the Ethernet protocol frames into individual PDUs for storage in a shared memory. The central computing platform further includes a plurality of parsing modules that are configured to access the individual PDUs from the shared memory and perform data processing on the individual PDUs.

First claim

What is claimed is:

1. A system for data processing and storage in vehicles having a zone-based, central computing in-vehicle communications network architecture, comprising:
a zone control unit (ZCU) that receives electronic messages from one or more sensors or electronic control units (ECUs) located within a zone of the vehicle, the ZCU comprising a protocol data unit (PDU) gating module that converts the electronic messages into a plurality of PDUs;
a switch-based Ethernet network that transmits the plurality of PDUs, using Ethernet protocol frames comprising the plurality of PDUs, to a central computing platform,
wherein the central computing platform comprises an Ethernet handler module that decomposes the Ethernet protocol frames into individual PDUs for storage in a shared memory, wherein the Ethernet handler module comprises a look-up table for decomposing Ethernet protocol frames based on FlexRay-originated PDUs into the individual PDUs for storage in the shared memory, and wherein the central computing platform further comprises a plurality of parsing modules that are configured to access the individual PDUs from the shared memory and perform data processing on the individual PDUs.

2. The system of claim 1 , wherein the ZCU further receives additional Ethernet protocol frames comprising a further plurality of PDUs from the switch-based Ethernet network and converts the further plurality of PDUs into electronic messages configured for sending to the one or more sensors or ECUs.

3. The system of claim 2 , wherein the switch-based Ethernet network further receives the additional Ethernet protocol frames from the central computing platform.

4. The system of claim 3 , wherein the Ethernet handler module is further configured to compose the further plurality of PDUs into the additional Ethernet protocol frames.

5. The system of claim 4 , wherein the plurality of parsing modules are configured to generate the further plurality of PDUs.

6. The system of claim 1 , wherein the electronic messages are formatted in one or more of controller area network (CAN), local interconnect network (LIN), and FlexRay.

7. The system of claim 1 , wherein the central computing platform comprises one or more of: an additional shared memory and an additional processing means, wherein the additional shared memory is accessible by the plurality of parsing modules and/or the additional processing means.

8. The system of claim 1 , wherein the Ethernet handler module receives the Ethernet protocol frames comprising the plurality of PDUs and provides the individual PDUs for storage in the shared memory on the basis of a blocking read and wait time schedule and/or a fixed cycle schedule.

9. The system of claim 8 , wherein the Ethernet handler module further comprises a buffer.

10. A vehicle comprising the system of claim 1 .

11. A method for data processing and storage in vehicles having a zone-based, central computing in-vehicle communications network architecture, comprising:
at a zone control unit (ZCU), receiving electronic messages from one or more sensors or electronic control units (ECUs) located within a zone of the vehicle,
at a protocol data unit (PDU) gating module of the ZCU, converting the electronic messages into a plurality of PDUs;
using a switch-based Ethernet network, transmits the plurality of PDUs, using Ethernet protocol frames comprising the plurality of PDUs, to a central computing platform;
at an Ethernet handler module of the central computing platform, decomposing the Ethernet protocol frames into individual PDUs for storage in a shared memory, wherein the Ethernet handler module comprises a look-up table for decomposing Ethernet protocol frames based on FlexRay-originated PDUs into the individual PDUs for storage in the shared memory; and
at a plurality of parsing modules the central computing platform, accessing the individual PDUs from the shared memory and performing data processing on the individual PDUs.

12. The method of claim 11 , further comprising receiving at the ZCU additional Ethernet protocol frames comprising a further plurality of PDUs from the switch-based Ethernet network and converting the further plurality of PDUs into electronic messages configured for sending to the one or more sensors or ECUs.

13. The method of claim 12 , further comprising receiving at the switch-based Ethernet network the additional Ethernet protocol frames from the central computing platform.

14. The method of claim 13 , further comprising composing at the Ethernet handler module the further plurality of PDUs into the additional Ethernet protocol frames.

15. The method of claim 14 , further comprising generating at the plurality of parsing modules the further plurality of PDUs.

16. The method of claim 11 , wherein the electronic messages are formatted in one or more of controller area network (CAN), local interconnect network (LIN), and FlexRay.

17. The method of claim 11 , wherein the central computing platform comprises one or more of: an additional shared memory and an additional processing means, wherein the additional shared memory is accessible by the plurality of parsing modules and/or the additional processing means.

18. The method of claim 11 , further comprising receiving at the Ethernet handler module the Ethernet protocol frames comprising the plurality of PDUs and providing the individual PDUs for storage in the shared memory on the basis of a blocking read and wait time schedule and/or a fixed cycle schedule.

19. The method of claim 18 , wherein the Ethernet handler module further comprises a buffer.
