Proposal to establish a Supplement to the 01 series of amendments to UN Regulation No. 171 on Driver Control Assistance Systems. The amendments modify technical requirements for system boundaries, driver disengagement detection, manoeuvre initiation, and driver unavailability response. New definitions for “Target Lane” and “Highway-like road” are introduced. Changes address system behaviour at boundary conditions, visual engagement criteria, and hands-off request withholding on highway-like roads. Testing and documentation requirements are revised to clarify Type Approval Authority responsibilities and manufacturer safety management processes during the operation phase.
The Task Force on Advanced Driver Assistance Systems held its 45th session on 3 March 2025 to review draft amendments to UN Regulation No. 171. Members confirmed editorial corrections to the 02 series of amendments and agreed to integrate them into a June WP.29 working document. CLEPA submitted three clarification proposals for the 02 series to be addressed via supplement if needed. Draft supplements to the original version and 01 series were introduced for GRVA consideration. The TF agreed to take a break before initiating Phase 4 development work and invited stakeholders to submit written proposals on future developments.
The meeting reviewed proposals for LED retrofit (LEDr) categories including H10 front fog lights and H9 high beam types for Regulation 37/RE.5. Key discussions addressed H10 failure requirements, H9 dual-voltage flux levels, and homogeneity requirements for B-type boxes. The task force also focused on market surveillance and enforcement mechanisms to ensure only approved LEDr products are used on public roads. The next meeting is scheduled for 20 April 2026.
Outcomes pursuant to Day 2 of the CLIV IWG session.
The 36th session of the Automotive Life Cycle Assessment IWG reviewed progress on a harmonised global methodology. SG7 will consolidate all comments by 1 April 2026 for line-by-line IWG review. Key unresolved items include PHEV methodology, component replacement approaches, and electricity modelling. Industry emphasised the need for a single global methodology and technology neutrality. The United States noted insufficient definition of methodological aspects. The group agreed to prioritise technical issues first, then policy-related issues, with virtual sessions in April and May. A decision point is targeted for 19 June 2026, with possible adoption at the October GRPE session. The IWG mandate extends to December 2026.
