Abstract

An apparatus and method for providing partial networking support for a vehicle, and an electronic control unit including the apparatus. The apparatus includes a service ID extraction unit configured to extract service ID information from a controller area network (CAN) frame or an Ethernet frame; a table search unit configured to search a predefined partial network table for service information and network information corresponding to the service ID information; a frame generation unit configured to generate a partial networking Ethernet frame based on the found service information; and a frame transmission unit configured to transmit the generated partial networking Ethernet frame to a network based on the found network information.

Claims

1. An apparatus capable of providing partial networking support for a vehicle, the apparatus comprising:

a service ID extraction unit configured to extract service ID information from a controller area network (CAN) frame or an Ethernet frame;

a table search unit configured to search a predefined partial network table for service information and network information corresponding to the service ID information;

a frame generation unit configured to generate a partial networking Ethernet frame based on the found service information; and

a frame transmission unit configured to transmit the generated partial networking Ethernet frame to a network based on the found network information.

2. The apparatus of claim 1, wherein the predefined partial network table includes service IDs, each indicating a type of service to be offered, a bitmap for representing location information about where an electronic control unit required for provision of service is located on a bus, and VLAN IDs and MPLS labels for data forwarding, the service information searched by the table search unit includes both VLAN ID information and MPLS label information, each of which corresponds to the service ID, and the network information searched by the service information is the location information represented by the bitmap regarding where an ECU is located on a bus.

3. The apparatus of claim 2, wherein the frame generation unit generates a partial networking Ethernet frame based on information about the VLAN ID corresponding to the service ID information in a case of the network using a VLAN service.

4. The apparatus of claim 2, wherein the frame generation unit generates a partial networking Ethernet frame based on information about the MPLS label corresponding to the service ID information in a case of the network using an MPLS service.

5. The apparatus of claim 3, wherein the frame generation unit generates the partial networking Ethernet frame containing data including E-type data for indicating a type of frame, the VLAN ID for data forwarding and an operation instruction for an ECU.

6. The apparatus of claim 4, wherein the frame generation unit generates the partial networking Ethernet frame containing data including E-type data for indicating a type of frame, the MPLS label for data forwarding and an operation instruction for an ECU.

13. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 1.

14. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 2.

15. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 3.

16. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 4.

17. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 5.

18. An electronic control unit comprising the apparatus capable of providing partial networking support for a vehicle as claimed in claim 6.

7. A method of providing partial networking support for a vehicle, the method comprising:

extracting service ID information from a controller area network (CAN) frame or an Ethernet frame;

searching a predefined partial network table for both service information and network information corresponding to the service ID information;

generating a partial networking Ethernet frame based on the found service information; and

transmitting the generated partial networking Ethernet frame to a network based on the found network information.

8. The method of claim 7, wherein the predefined partial network table includes service IDs, each indicating a type of service to be offered, a bitmap for representing location information about where an electronic control unit required for provision of service is located on a bus, and VLAN IDs and MPLS labels for data forwarding, the service information searched by the table search unit includes both VLAN ID information and MPLS label information each of which corresponds to the service ID, and the network information searched by the service information is the location information represented by the bitmap regarding where an ECU is located on a bus.

9. The method of claim 8, wherein the generating of the partial networking Ethernet frame comprises generating the partial networking Ethernet based on information about the VLAN ID corresponding to the service ID information in a case of the network using a VLAN service.

10. The method of claim 8, wherein the generating of the partial networking Ethernet frame comprises generating the partial networking Ethernet based on information about the MPLS label corresponding to the service ID information in a case of the network using an MPLS service.

11. The method of claim 9, wherein the generating of the partial networking Ethernet frame comprises generating the partial networking Ethernet frame containing data including E-type data for indicating a type of frame, the VLAN ID for data forwarding and an operation instruction for an ECU.

12. The method of claim 10, wherein the generating of the partial networking Ethernet frame comprises generating the partial networking Ethernet frame containing data including E-type data for indicating a type of frame, the MPLS label for data forwarding and an operation instruction for an ECU.
