Monday 18 May 2026 will cover adoption of the agenda, highlights of the March 2026 WP.29 session, artificial intelligence in vehicles, and connected vehicles including cyber security, software updates, data protection, and data communication. Tuesday 19 May will address automated and autonomous connected vehicles, including IWG on ADS, GRVA workshops, EDR/DSSAD deliverables, and UN R157. Wednesday 20 May will cover driver control assistance systems, UN R79, acceleration control, emergency lane keeping, and advanced emergency braking. Thursday 21 May will address advanced driver assistance systems covering UN Regulations Nos. 13, 13-H, 139, 140 and UN GTR No. 8, motorcycle braking, and UN R90. Friday 22 May will cover revision 3 to the 1958 Agreement and other business.
Proposal to amend Annex 8, para. 3.4.1. to require the manufacturer’s statement and explanation to address how the chosen strategy will not prejudice safe operation of systems involved in achieving the function of the system, such as tyres or wheels, and to require the Technical Service to assess the explanation and validation plan, and amend Annex 8, para. 3.4.4. to require documentation to include analysis of faults with other systems involved in achieving the function of the system and to require the Technical Service assessment to include inspection of the safety approach at vehicle level with confirmation of consideration of interactions with other vehicle systems. The proposal responds to a fatal collision where a tyre failure combined with ABS activation resulted in unsafe braking performance. Expanding the functional safety assessment beyond the braking system to include all relevant systems ensures all faults influencing system function are captured.
Proposal to amend para. 137 to describe the seventeenth workshop organized in Bangkok, Thailand, together with the twentieth session of the IWG on ADS, where participants reviewed updates to the GID document sections prepared by the OPIs, resulting in a revised version of the GID document considered mature enough for presentation at the twenty-fifth GRVA session, with agreement that remaining open items should be finalized at the July 2026 workshop in Brussels, Belgium, and several minor amendments to the draft GTR/UN-R text derived from the Bangkok meeting discussions modified the text of the draft GTR/UN-R.
The EV/HFCV Retrofit Systems IWG held three meetings since the last GRVA session and has compiled requirements for Electrical Safety (UN R100), Braking (UN R13/R13H), Cybersecurity (UN R155), and EMC (UN R10) with participation of respective GRs experts. Regulation drafting has started. Next activities include continuation of discussion on requirements, addressing net power and electric consumption determination, family and parent definition, and provisions for PTI, with regulation draft for EV retrofit to be delivered as informal document to the next GRPE session in October.
Proposal to insert new para. 3.1.1. and 3.1.2. requiring manufacturers to provide information to approval authorities prior to application and upon extension of type approval; insert new para. 3.2.2. requiring manufacturers to provide summaries of safety definitions, driver safety levels, traffic rules assessment, and testing for each territory where ALKS can be active; and insert new paras. 4.6. to 4.6.6. establishing procedures for approvals covering multiple territories, including notification of receiving approval authorities at least 30 days before approval, review periods, and dispute resolution under the 1958 Agreement. OICA and CLEPA do not support mandatory pre-announcement but would support sharing Safe Operation documentation and lists of compliant territories during the approval process.
Proposal to amend ECE/TRANS/WP.29/2026/137 to replace placeholder text “[ADS]”, “[XXX]”, and “[number of this Regulation]” with the UN Regulation number upon adoption, amend the cross-reference in paragraph 1.2. to “7.2.3.17.”, amend paragraph 6.2.2.3.8.1. subparagraph (b) to specify gaze directed to “the” driving task relevant area, remove brackets around “7.4.” in paragraph 11.2., add a period after the number in Annex 1 paragraph 5.1., amend Annex 1 Appendix 1 paragraphs 1.4.5. and 1.4.7., renumber paragraphs 1.4.12., 1.4.12.1., and 1.4.12.2. as 1.4.11.5., 1.4.11.5.1., and 1.4.11.5.2., amend Annex 1 Appendix 2, amend Annex 7 table 5 rows 1 and 2 column 7, remove brackets in Annex 8 paragraphs 5.3.1. and 5.3.2., and insert “Mandatory” in Annex 8 table row 1 column 2.
This Guidance and Interpretation Document (GID), based on GRVA/2026/3 as amended by GRVA-24-29 and WP.29-198-09, supports implementation of proposed UN Global Technical Regulation and UN Regulation on Automated Driving Systems. The GID, structured in table format with regulatory text and explanatory guidance with examples, facilitates interpretation of ADS requirements when applying them to particular vehicles or vehicle types. The document addresses ADS safety, system descriptions, operational design domains, performance in nominal, critical, and failure situations, interactions between ADS and users, manufacturer safety management systems, test environments including simulation credibility frameworks, safety cases, post-deployment safety monitoring, and compliance assessments including confirmatory testing. Materials will be restructured and refined for submission to GRVA’s September 2026 session.
Since the 24th session of GRVA, the Workshops on Automated Driving Systems held four sessions, with meetings in Shanghai and Bangkok. Administrative requirements for the draft UNR/GTR ADS require no further discussion. Task 3 developed interpretations and guidance for implementation, consolidated in a draft Guidance and Interpretation Document presented as informal document GRVA-25-20, with remaining items for refinement at a July Brussels hybrid joint IWG/WS session. The GID will be made available in English, French, and Russian, with the IWG ADS maintaining it. Formal adoption is projected for November WP.29 following September GRVA discussion.
GRVA may wish to review proposals for amendments to UN Regulation No. 78 (Motorcycle and Moped Braking), if any.
