METHOD AND SYSTEM FOR PROVIDING OPTIMIZED ETHERNET COMMUNICATION FOR VEHICLE
First Claim
1. A method for allocating an address to an Electronic Control Unit (ECU) on an in-vehicle Ethernet network comprising:
- allocating a first address value to identify the in-vehicle Ethernet network;
allocating a second address value to identify a domain corresponding to the ECU;
allocating a third address value to identify a group of ECUs in the domain;
allocating a fourth address value to identify the ECU in the group; and
generating an Internet Protocol (IP) address including the allocated first to fourth address values,wherein the generated IP address is set as a fixed IP address of the ECU.

Abstract
Disclosed are methods for allocating an address to an Electronic Control Unit (ECU) on an in-vehicle Ethernet network and devices therefor. A method may include allocating a first address value identifying the in-vehicle Ethernet network, allocating a second address value identifying a domain corresponding to the ECU, allocating a third address value identifying a group of ECUs in the allocated domain, allocating a fourth address value identifying the ECU in the group, and generating an IP address including the allocated first to fourth address values. The generated IP address is set as a fixed IP address of the ECU.

11. A device for allocating an address to an Electronic Control Unit (ECU), the device comprising:
-
a unit configured to receive first information that identifies a domain connected to a gateway; a unit configured to receive second information that identifies the ECU in the domain; a unit configured to generate an IP address corresponding to the first information and the second information with reference to a pre-defined IP address allocation rule; and a unit configured to allocate the generated IP address to the ECU, wherein the ECU is connected to an in-vehicle Ethernet network. - View Dependent Claims (12, 13, 14, 15, 16)

17. A gateway for allocating an address to an Electronic Control Unit (ECU) connected to an in-vehicle Ethernet network, the gateway comprising:
-
a unit configured to receive an in-vehicle Ethernet routing table, in which IP addresses allocated to the ECU according to domains and groups of the in-vehicle Ethernet network are mapped, from an external device; a unit configured to set an IP address allocated to the ECU using the in-vehicle Ethernet routing table; and a unit configured to transmit the in-vehicle Ethernet routing table to the ECU using the set IP address, wherein the gateway and the ECU control transmission and reception of an IP packet using the in-vehicle Ethernet routing table. - View Dependent Claims (18, 19, 20, 21, 22)
