Proposal to insert para. 5.3.7.2.1.13. to require manufacturers to describe system behaviour when driver disengagement is detected during manoeuvres, amend para. 4.2.5.2.19.2.1. of Annex 4. to specify test execution with different target vehicle types or categories, overlaps, lane positions, and static target positions, amend para. 3.5.1. of Annex 3. to require manufacturers to demonstrate safety management system compliance to the Type Approval Authority at least every three years, amend para. 2.3.2. of Appendix 2 of Annex 3. to reference renumbered provisions, and amend para. 4.2.5.2.14.1.2. and 4.2.5.2.14.2.1. of Annex 4. to clarify test scenarios and target vehicle specifications.
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.
Proposal to amend WP.29/2026/139 to amend para. 4.2.2.3.8.1. subparagraph (b) regarding user engagement to resume the DDT, insert new para. 5.2.1.8.1. requiring manufacturers to document simulation toolchain scope and limitations, amend para. 5.2.1.3.1. regarding manufacturer management of relevant data, amend para. 5.3.1.16. describing ADS responses to failure situations, amend para. 6.3.2.2.3. regarding scenario assessment, amend para. 6.3.3.3.1. regarding confirmatory track testing provisions, amend Annex 5 Tables 3, 4, and 5 regarding scenario specifications and risk manoeuvre conditions, and amend Annex 6 para. 5.3.1. and 5.3.2. regarding DSSAD recording requirements and intervals.
Proposal to introduce new regional requirements from Contracting Parties, in particular from Euro 7 in the EU, including new particle number (PN10) provisions, a new SHED limit for evaporative emissions, updated On-board Fuel Consumption Monitoring provisions, and new annexes with requirements relating to in-vehicle battery durability and a new test for range of Pure Electric Vehicles at low temperatures for UN R154 (Worldwide harmonized Light vehicles Test Procedures (WLTP)).
Devices for monitoring on-board vehicle consumption of fuel and/or electric energy shall determine and store lifetime values of fuel consumed, distance travelled, and energy parameters specified in Appendix 5. Type-approval requires testing per Table A according to vehicle category and fuel type, including Type 1 emissions tests, evaporative emissions tests, durability, OBD checks, and OBFCM accuracy verification. Manufacturers must ensure OBFCM accuracy between −0.05 and +0.05 calculated using specified formulae comparing WLTP-determined and OBFCM-measured consumption. Conformity of production requires periodic testing and audits. Lifetime counter values shall be preserved from 1 January 2029 for new vehicle types; from 1 January 2030, type approvals for non-compliant vehicles shall not be accepted. OBFCM devices must provide standardised, unrestricted access to information via specified ISO and SAE standards.
TF-AVRS submitted a draft new Y-category Passive Safety Regulation to GRSP-79 in June 2026. The regulation addresses fuel system integrity, electrical shock protection, and crash compatibility for frontal, rear-end, and lateral collisions. The Task Force eliminated the R point problem, passenger compartment references, and A and B pillar designations, harmonised mass definitions, and consolidated numbering and cross-references. Open items include determining additional requirements, specific vehicle measurements, and finalising Annex elements. Subsequent informal documents are planned for GRSP-79, with working documents for GRSP-80.
Proposal to delete the draft “Reserved” paragraph 5.3.7.2.4.3. in GRVA/2026/18. Reserving paragraph 5.3.7.2.4.3. in the 01 series would mean that the subsequent paragraphs would be out of line with the numbering in the 02 series, making future amendments to UN R171 unnecessarily challenging.
Proposal to delete paragraph 1.2.6. excluding e-axle trailers with e-axles providing electric propulsion and/or incorporating an electric regenerative braking system from the scope of UN R13, and add definitions of “e-axle,” “e-axle trailer,” “dynamo function,” and “e-trailer”; add special requirements for power-driven vehicles supporting e-trailer operation, e-axle trailers equipped with dynamo function, and e-trailers of category O; add requirements for electric control lines conforming to ISO 11992-2:2027; specify message support and functional compatibility; and add provisions for electric regenerative braking, dynamo function, and propulsion, including parameters such as retarder torque demand priority, propulsion force limits, overriding mode activation at speeds below 15km/h, and vehicle stability function interaction.
91. GRVA adopted on 24 June 2025 the list of proposed decisions (GRVA-22-04/Rev.1), taken over in this report.
