Full title and description

Intelligent transport systems — Lane departure warning systems — Performance requirements and test procedures. This International Standard defines and sets performance and test requirements for in‑vehicle lane departure warning (LDW) systems intended to warn drivers of an unintended lane departure on highways and highway‑like roads; the document covers system definition, classification, functions and human–machine interface (HMI) aspects.

Abstract

ISO 17361:2017 specifies definitions, functional classifications, HMI requirements and test methods for lane departure warning systems (LDW). The standard applies to passenger cars, commercial vehicles and buses. LDW systems covered by the standard provide driver warnings only and do not require the system to perform automatic corrective steering or braking; temporary or irregular lane‑marking situations (for example roadworks) are excluded from the scope of the test procedures.

Scope

Specifies performance requirements and test procedures for lane departure warning systems that issue a warning when a vehicle is unintentionally departing its lane on highways and highway‑like roads. The standard addresses system definition, functional classification, human–machine interface (visual, audible, haptic warnings), and laboratory/road test methods to evaluate LDW behaviour under defined lane‑marking and driving conditions. Systems that take automatic corrective action to prevent lane departure are outside this standard’s remit.

Key topics and requirements

• Definition and classification of LDW system types (warning only; sensor technologies may include camera, radar, GPS and others).
• Functional requirements for when and how warnings are issued (including driver intent detection such as indicators/blinkers).
• Human–machine interface (HMI) requirements (visual, audible and haptic warning modalities and ergonomics).
• Performance metrics and pass/fail criteria for detection, false alarm rates and warning timing under specified road/lane‑marking conditions.
• Test procedures and conditions for laboratory and on‑road evaluation; exclusions for temporary or irregular lane markings (e.g., work zones).
• Applicability statements: passenger cars, commercial vehicles and buses; responsibility for safe vehicle operation remains with the driver.

Typical use and users

Used by automotive OEMs and Tier‑1 ADAS suppliers to specify and verify LDW functionality, by test laboratories and certification bodies for performance verification, and by regulators and safety assessors as a reference for ADAS behavior and test methods. Automotive systems engineers, HMI designers, ADAS validation teams and research organizations studying lane‑keeping and driver assistance systems are frequent users.

Related standards

Commonly referenced alongside automotive safety standards and ADAS guidance such as ISO 26262 (functional safety) and ISO 21448 (SOTIF — Safety of the Intended Functionality). Regulatory and type‑approval texts for steering/ADAS and LDW (for example UNECE regulations covering lane‑related functions) and industry test protocols (e.g., Euro NCAP ADAS test protocols) are often used in conjunction with ISO 17361.

FAQ

Q: What is this standard?

A: ISO 17361:2017 is an international standard that defines performance requirements and test procedures for lane departure warning systems in road vehicles, including definitions, classification and HMI requirements.

Q: What does it cover?

A: It covers warning‑only lane departure systems (how they detect lane departure, when they should warn the driver, HMI requirements and the tests to confirm performance). It explicitly excludes systems that perform automatic corrective actions to prevent lane departure and excludes test expectations for temporary or irregular lane markings.

Q: Who typically uses it?

A: Vehicle manufacturers, ADAS suppliers, test laboratories, regulatory assessors, and safety researchers use ISO 17361 to specify, validate and assess LDW performance.

Q: Is it current or superseded?

A: The 2007 edition was superseded by ISO 17361:2017 (Edition 2). The 2017 edition was reviewed/confirmed and an amendment (ISO 17361:2017/Amd 1:2023) was issued — the 2017 edition with the 2023 amendment is the current published version.

Q: Is it part of a series?

A: It is a stand‑alone ISO standard for LDW but is typically used together with broader automotive safety and ADAS standards such as ISO 26262 (functional safety) and ISO 21448 (SOTIF), plus regional vehicle‑type approval regulations for ADAS.

Q: What are the key keywords?

A: Lane departure warning, LDW, lane detection, ADAS, HMI, performance requirements, test methods, ISO 17361.
