The Informal Working Group on Automotive Life Cycle Assessment decided not to submit the Working Document for the 95th GRPE session. The Mutual Resolution will not be submitted for adoption at the October 2026 GRPE session due to unresolved issues and lack of consensus. The leading team will prepare a status report for October 2026 GRPE describing progress, current status, remaining issues, and proposed way forward. A revised Terms of Reference extending the IWG mandate will be prepared. An additional meeting may be organized to determine the future work programme.
RD-ASEP includes technical background and vehicle application guidance for Real Driving Additional Sound Emission Provisions under UN R51.03 Supplement 7 Annex 9 for the mandatory monitoring phase between 07/2023 and 06/2024. RD-ASEP, referenced in GRB-68-03, applies to vehicles of category M1 and N1 equipped with internal combustion engines and covers engine speeds up to 95% of typical driving in speed ranges applicable to sub-urban conditions. A Sound Expectation Model predicts vehicle sound levels at randomly selected operation conditions by splitting measured pass-by test results into tyre rolling sound, mechanical no-load sound, and dynamic sound components, using reference values from Annex 3 type approval tests with logarithmic functions and parameter table slopes. Compliance assessment allows measured sound to exceed calculated expected sound by not more than 2 dB for maximum two test runs out of fifteen. Model validation with 2024 monitoring database confirms the tyre rolling sound and power train sound models represent well approved tyres and engines, with less than 5 dB typically separating pass-by run results from the limit.
The Informal Working Group on Advanced Emergency Braking System held its 2nd meeting on 18 June 2026. Australia had submitted documents GRVA/2026/21 and GRVA-25-36 proposing amendments to UN R152. For para. 2.14, the group agreed to insert a footnote stating “this value is understood to be a minimum value,” with a working document to be prepared for next GRVA. For para. 5.2.1.1, Australia withdrew its proposal to remove the 0.8s TTC warning condition after safety concerns were raised. CLEPA-OICA, UK and Australia will prepare a clarification proposal for next GRVA.
This document presents draft provisions for UN Regulation No. 11 concerning door latches and door retention components. Inspired by justifications in GRSP-79-19 and GRSP-78-48, amendments address vehicles equipped with Automated Driving System features (ADSF-1 and ADSF-2), extending requirements to vehicles of category X while excluding category Y. Key EDO additions include definitions for latch release controls, door handles, power loss, and unlock/unlatch operations. New performance requirements mandate intuitive latch release controls and door handles; power-assisted exterior and interior controls must remain functional for at least 60 minutes after power loss through secondary mechanical means, active secondary power supplies, or fail-safe principles. Annex 7 introduces a power loss test procedure verifying door operability following emergency events, with interior and exterior opening procedures conducted within 10 minutes after 60-minute power disconnection periods.
The agenda includes adoption of the provisional agenda and minutes from the thirty-eighth session; proposals for amendments to R155 concerning multistage vehicles, separate technical units and component approval, and remote operation for automated driving systems; review of cyber and software requirements in the ADS Regulation; application of RXSWIN to R156; administrative provisions in R155 and R156 regarding Type Approval Authority for CSMS/SUMS and issuing approvals for out-of-scope vehicle types; and preparation of GRVA 26.
AI IWG 12th session will be held October 26–27, 2026, at the Zennihon Truck Sogo Kaikan, 3rd Floor, Tokyo. October 26 runs 10:00–17:30 with reception at 18:30; October 27 runs 09:30–17:00. The meeting room opens 9:30 a.m. October 26 and 9:00 a.m. October 27. In-person attendance is limited to the first 50 registrants. Participants must complete the survey by September 25. JASIC staff contact information and accommodation recommendations are provided.
Proposal to amend para. 1.1. to clarify that the Regulation applies to vehicles of categories M1 and N1 with respect to latches, door retention components, latch release controls, and door handles to prevent the risk of occupants being thrown from a vehicle and to ensure evacuation at emergency events, insert new paras. 2.30. to 2.36. defining latch release control, door handle, retractable door handle, unlock, unlatch, door opening, and power loss, insert new para. 5.4. establishing exterior and interior door operation requirements, insert new para. 6.4. establishing requirements for latch release controls and door handles to be intuitive and to remain capable of operating after power loss for at least 60 minutes, and insert new Annex 7 establishing a power loss test procedure to verify door opening systems remain functional following an emergency event leading to loss of the vehicle’s ordinary power supply.
Proposal to insert new paragraphs in Section I providing background on GTR No. 1, discussions on door operation requirements including functional distinctions between unlocking, unlatching and opening, intuitive operation, continued operation after power loss, interior egress, exterior rescue access, retractable door handles, power-assisted door opening, and testing procedures, insert new paras. 3.25. to 3.31. defining latch release control, door handle, retractable door handle, unlock, unlatch, door opening, and power loss, insert new para. 4.3. establishing exterior and interior door operation requirements for doors providing direct occupant access, insert new para. 5.4. specifying that operating methods of latch release controls and door handles shall be intuitive, that power-assisted latch release controls shall remain capable of unlatching doors after power loss for at least 60 minutes by secondary mechanical means, active secondary power supply, or fail-safe systems, that power-assisted unlocking and unlatching controls shall remain functional after power loss for at least 60 minutes, that power-assisted door opening systems shall remain capable of opening doors by manual force after power loss, that door handles including retractable handles shall provide accessible gripping features after power loss, and that unlock means and latch release controls shall be unobstructed and directly visible from occupant positions and not located in storage devices, and insert new Annex 6 establishing power loss testing procedures for interior and exterior door operations with 60-minute waiting periods and 10-minute testing windows requiring repeated opening cycles up to five times per door.
117. No document was submitted under this agenda item.
118. The secretariat informed GRVA that an erratum for UN Regulation No. 152 was under preparation. He mentioned actions taken to correct the French version of Mutual Resolution No. 2.
