Full title and description

Road vehicles — Local Interconnect Network (LIN) — Part 1: General information and use case definition. This part provides an overview of the structure and partitioning of the ISO 17987 series and defines the common terminology and primary use cases for LIN communication systems in road vehicles.

Abstract

This document gives an overview of the structure and the partitioning of the ISO 17987 series and outlines the use cases where the ISO 17987 series is used. The terminology defined here is common for all LIN communication systems and is used throughout the ISO 17987 series. It has been established to define and clarify LIN use cases for automotive applications.

Scope

ISO 17987-1:2025 establishes the high-level scope and purpose of the ISO 17987 series: to define terminology, describe the series partitioning (how parts are organized), and document the typical use cases for LIN in road-vehicle environments. It is intended to be the reference for how subsequent parts of the series (protocol, transport, electrical/physical layers, etc.) interrelate and where each is applied within vehicle systems.

Key topics and requirements

• Overview of the ISO 17987 series structure and part partitioning.
• Definition of common terminology and vocabulary used across all LIN parts.
• Documentation and classification of LIN use cases in vehicle subsystems (e.g., body electronics, sensors, actuators).
• Guidance on where to apply each part of the series (protocol, transport, network services, electrical/physical layer).
• Reference alignments to related in-vehicle network specifications and interoperability considerations.

Typical use and users

Used by automotive OEMs, Tier‑1 and Tier‑2 suppliers, ECU and module designers, in-vehicle network integrators, test and validation laboratories, tool vendors, and standards bodies. Typical applications include specifying LIN topology and behavior for body-control modules, sensor/actuator connections, and other low-speed in-vehicle sub-networks where LIN is appropriate.

Related standards

ISO 17987-1 is the introductory part of the ISO 17987 series. Other parts in the series (updated in 2025) cover the transport protocol and network layer services (Part 2), the protocol specification (Part 3), and the electrical/physical layer (Part 4). Older 2016 editions of some parts have been withdrawn and replaced by the 2025 editions.

FAQ

Q: What is this standard?

A: ISO 17987-1:2025 is the first part of the ISO 17987 series for Local Interconnect Network (LIN) in road vehicles; it provides general information, series structure and use case definitions for LIN.

Q: What does it cover?

A: It covers an overview of the series partitioning, common terminology for LIN systems, and the typical use cases where LIN is applied in vehicle architectures. It does not itself specify protocol bit-timings or electrical parameters (those are handled in other parts of the series).

Q: Who typically uses it?

A: Automotive manufacturers, module and ECU suppliers, system integrators, test houses, tool vendors and anyone designing or validating LIN-based sub-networks in vehicles.

Q: Is it current or superseded?

A: ISO 17987-1:2025 is the current edition (published 1 May 2025) and supersedes the previous 2016 edition of ISO 17987-1.

Q: Is it part of a series?

A: Yes. It is Part 1 of the ISO 17987 series; related parts cover transport protocol/network services (Part 2), protocol specification (Part 3), and electrical physical layer (Part 4), all updated in the 2025 revision cycle.

Q: What are the key keywords?

A: LIN, Local Interconnect Network, in-vehicle network, ISO 17987, terminology, use cases, transport protocol, network layer, protocol, physical layer.
