Comments on the structure and content of the draft reference document on artificial intelligence in regulated automotive safety systems. Notes a six-month timeline for adoption by WP.29 in June 2027, with formal submissions due by March 2027. Recommends prioritizing a future-proof repository of information on potential AI-related risks and risk management that can be maintained through standard WP.29 processes. States current regulatory frameworks are sufficient to address unreasonable safety risks from AI use in vehicles. Suggests the document should include introductory explanatory text for non-specialists, clear definitions of technical terms, accessible risk summaries, and a developed risk-management section to support WP.29 regulatory activities.

Proposed Terms of Reference and Rules of Procedures for the AC.2/WP.29 Informal Group on Prioritization. The IWG-Prio shall develop recommendations on prioritizing activities based on alignment with strategies, regulatory urgency, safety and environmental benefits, resource implications, duplication avoidance, interested parties, and governance of legal instruments. The IWG-Prio shall conduct high-level review of ongoing and proposed activities, develop recommendations regarding initiation and continuation of regulatory activities, identify opportunities to improve efficiency of WP.29 activities including coordination among groups and meeting scheduling, and provide a framework for common understanding of prioritization. The IWG-Prio shall prepare recommendations for non-binding guidance material and proposed procedures for consideration by AC.2 and WP.29 no later than their November 2028 session. The IWG-Prio shall be placed under WP.29, open to all WP.29 participants, chaired by one of the Vice-Chairs of WP.29, and shall operate in English with decisions reached by consensus.

Proposal to amend para. 6.27.9.1. to exclude direction indicator lamps and dipped-beam headlamps from the 700 cd maximum luminous intensity limitation on or above the HH line when used as answer-back signals, allowing these devices to operate with their original specifications, while maintaining the restriction on front fog lamps, rear fog lamps, and stop lamps.

Proposal to amend para. 2.4.10. to define a pair for vehicles of categories M, N and O as one or more lamp(s) extending from left to right-hand side, amend para. 2.4.11. and 2.4.12. to define single and multiple lamps and interdependent lamp systems marked Y, amend para. 5.5. and its sub-paragraphs to establish requirements for paired lamps including symmetry and photometric characteristics, amend para. 5.7.2.2. and 5.7.2.3. to specify installation requirements for single lamps, delete para. 5.7.2.4. concerning positioning and length requirements, amend para. 5.18.2. regarding assembly of lamps marked D, add para. 4.7.3. to UN Regulation No. 148 requiring a pair to contain at least one light source on each side, and amend para. 4.8.1.3. to clarify photometric measurement procedures when lamps use multiple light sources.

Draft priority work programme for GRE addressing simplification and update of UN Regulations Nos. 48, 53, 74, 86, 148, 149 and 150 to become future proof and technology neutral with performance-based test requirements by 2027; further development of EMC requirements in 08 series of amendments to UN Regulation No. 10 by 2028; reduction of lamp glare with recommendations by 2026; lighting performance visibility and glare prevention by 2027; development of ADS marker lamps for automated vehicles; new LED replacement light sources categories; adaptation to technical progress; energy indicator and lamp test mode by 2027; optical sensor requirements; and sustainability considerations.

Proposal to amend para. 4.5.5. to permit the internal structure of optical components and the texture of the outer lens of a lamp to incorporate one manufacturer logo built by transparent or non-transparent components, subject to conditions: only the logo of the vehicle manufacturer or body manufacturer brand name is allowed; the enclosed light emitting surface of the logo shall not exceed 100 cm²; graphic marks, emblems, words, or combinations smaller than 5 cm² are not to be considered as a manufacturer logo; the logo light emitting surface does not have to be symmetrical; and stop lamps, direction indicator lamps, reversing lamps, and side-marker lamps shall not incorporate a logo unless the rearmost side-marker lamp is grouped, combined, or reciprocally incorporated with the rear position lamp.

Meeting report documenting discussions on proposed amendments to the driver drowsiness alert warning (DDAW) system regulation. Topics addressed include: clarification of warning acknowledgement and continued monitoring; mandatory microsleep detection as a distinct safety-critical event; expanded operating conditions for system effectiveness; interaction between DDAW and Driver Control Assistance Systems (DCAS); system performance under driver occlusions such as eyewear; drowsiness warning thresholds and advisory information; false negative event classification methodology; test participant selection and validation procedures; specificity and positive predictive value as performance metrics; and Observer Rated Drowsiness (ORD) as an alternative to KSS measurement. The IWG discussed these proposals to inform development of a 01 series of amendments to UN Regulation No. 182.

Presentation comparing results of Switzerland’s NExUS study on electric vehicles and internal combustion engine vehicles with RD-ASEP Sound Expectation Model predictions. NExUS study objective was to compare EVs with ICE vehicles of the same consumer segment to better understand EV modelling. Key findings show overall sound levels of EVs and modern ICEs are close under constant speed, while ICE sound is higher under low-speed acceleration. RD-ASEP SEM predictions align closely with NExUS measurements for both accelerated and constant speed conditions.
