ISO 17361:2017/Amd 1:2023

Overview

ISO 17361:2017/Amd 1:2023 is an important amendment to the international standard focused on Intelligent Transport Systems (ITS), specifically addressing Lane Departure Warning Systems (LDWS). This standard, developed by ISO technical committee ISO/TC 204, defines the performance requirements and test procedures for LDWS to enhance road safety by alerting drivers when their vehicle unintentionally departs from its lane.

The 2023 amendment introduces key updates to testing speeds for different vehicle classes, reflecting the evolving technical and safety considerations in intelligent transport. By adhering to this standard, manufacturers and testing organizations ensure that LDWS technologies meet consistent quality and reliability benchmarks worldwide.

Key Topics

• Lane Departure Warning System Performance: The standard outlines how LDWS must perform under various driving conditions to reliably detect lane departures and warn drivers, reducing accident risks caused by unintentional lane drifting.

• Test Procedures: Defines rigorous procedures and scenarios to test LDWS effectiveness, including detection algorithms, warning timing, and system accuracy for different vehicle categories.

• Vehicle Classes and Speed Specifications: The 2023 amendment updates speed criteria - Changing speeds from “17 m/s for Class I and 20 m/s for Class II” to “20 m/s for Class I and 17 m/s for Class II,” reflecting nuances in vehicle dynamics and system response requirements.

• International Standardization: Harmonizes LDWS requirements across markets, facilitating global compatibility for ITS devices, easing regulatory compliance, and supporting international trade.

• Safety and Reliability: Emphasizes system robustness and real-world applicability to ensure LDWS contributes effectively to accident prevention and driver assistance.

Applications

• Automotive Manufacturing: OEMs integrate ISO 17361 compliant LDWS into vehicles to meet safety regulations and consumer expectations for advanced driver assistance systems (ADAS).

• Testing and Certification: Vehicle testing laboratories use the standard’s specified test procedures to verify LDWS performance for certification and regulatory approval.

• Intelligent Transport Systems Development: Developers of ITS technologies leverage this standard to design and validate lane adherence features that enhance automated vehicle safety.

• Road Safety Programs: Regulators and policymakers adopt the standard to set minimum performance thresholds for LDWS, promoting safer road environments.

• Aftermarket Safety Devices: Manufacturers of aftermarket lane departure warning products use these requirements to ensure compatibility and effectiveness with various vehicle types.

Related Standards

• ISO 26262 - Functional safety of road vehicles, covering safety requirements for electronic systems including LDWS components.

• ISO 14813 - Reference model for intelligent transport system architectures, supporting system-level integration of LDWS.

• ISO 19091 - Cooperative ITS, relates to how LDWS can be enhanced via vehicle-to-infrastructure communications.

• ISO/IEC 27000 series - Information security standards relevant to protecting LDWS software and communications.

• UNECE WP.29 Regulations - Vehicle safety and software update regulations that often reference international standards for ADAS systems.

Conclusion

ISO 17361:2017/Amd 1:2023 represents a critical evolution of the global framework for lane departure warning systems in intelligent transport. By clearly defining updated performance requirements and test methods, it supports safer roads and innovation in automotive safety technology. Adherence to this standard enhances LDWS reliability, facilitates regulatory compliance, and promotes harmonized ITS development worldwide. For automotive manufacturers, testers, and regulators, ISO 17361 remains a foundational document for advancing driving assistance systems that prevent lane departure-related accidents.
