GB/T 43258.3-2023Road vehicles - Diagnostic communication over Internet Protocol (DoIP) - Part 3: Wired vehicle interface based on IEEE 802.3 (English PDF)

Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020,

Directives for standardization - Part 1: Rules for the structure and drafting of

standardizing documents.

This document is part 3 of GB/T 43258 Road vehicles - Diagnostic communication over

Internet Protocol (DoIP). The following parts have been issued for GB/T 43258:

— Part 2: Transport protocol and network layer services;

— Part 3: Wired vehicle interface based on IEEE 802.3;

— Part 4: Ethernet-based high-speed data link connector.

This document adopts ISO 13400-3:2016 Road vehicles - Diagnostic communication

over Internet Protocol (DoIP) - Part 3: Wired vehicle interface based on IEEE 802.3

by modification.

Compared with ISO 13400-3:2016, this document makes the following structural

adjustments:

— 4.2 corresponds to Clause 4 of ISO 13400-3:2016;

— Figures 3 ~ 8 correspond to Figures 2 ~ 7 in ISO 13400-3:2016;

— Tables 1 ~ 4 correspond to Tables 2 ~ 5 in ISO 13400-3:2016.

The technical differences between this document and ISO 13400-3:2016, and the causes

for these differences are as follows:

— REMOVE the reference and description of ISO 13400-1 which has been abolished;

— USE the normatively referenced GB/T 40822-2021 to replace ISO 14229 (see

Clause 3), to adapt to technical conditions in China and improve the operability;

— ADD "4.1 Symbol", to improve the usability of the document;

— ADD the definition of VpullupSource (see 4.1), to improve the usability of the

document;

— ADD the abbreviated terms GND, WoL and XFRM (see 4.2), to improve the

usability of the document.

1 Scope

This document specifies the vehicle communication interface and test equipment

requirements for a physical and data link layer based on IEEE 802.3 100BASE-TX.

This document applies to the design for the physical and data link layer in vehicle

communication interface and test equipment based on IEEE 802.3 100BASE-TX.

This interface serves as the physical basis for IP-based communication between the

vehicle and test equipment. This document specifies the following aspects:

— requirements for signal and wiring schematics in order to ensure physical layer

compatibility of the vehicle interface and Ethernet networks and test equipment

communication interfaces;

— discovery/identification of the in-vehicle diagnostic Ethernet interface;

— activation and deactivation of the in-vehicle diagnostic Ethernet interface;

— mechanical and electrical diagnostic connector requirements;

— this edition has been modified to include the identification of two Ethernet pin

assignments.

port of the patch cable are connected to the Rx pins on the destination port and

vice versa.

Depending on the Auto-MDI(X) capabilities of the Ethernet implementation, it is

possible that cross-linked connections or 1:1 connections can be used interchangeably.

This depends on the Auto-MDI(X) capabilities of the PHY. The Auto-MDI(X) feature

was developed to allow for plug and play use of both types of patch cable.
