The meeting will include welcome and opening remarks, adoption of the agenda, presentation of the rationale and Terms of Reference adopted by the 26th GRVA, presentation of the Task Force’s work perspectives and timeline for 2027 including expected achievements and key deliverables, invitations for dedicated presentations from Contracting Parties and non-governmental organizations on their contributions and ongoing work on scenarios, requests for participant feedback and priorities for 2027, and concluding remarks with agreement on next steps.
Proposal to amend UN Regulation No. 51 concerning approval of motor vehicles with regard to sound emissions. The document provides comprehensive specifications for noise measurement methods and limits for vehicles of categories M and N, including:
Draft agenda for the nineteenth meeting of the Task Force Data Analysis, a subgroup to IWG RD-ASEP, scheduled for 2 November 2026. The meeting will address continued discussion on amendments to RD-ASEP, including consideration of LDYN definition, simplified assessment methods for EV, rounding procedures, and temperature correction. Open items concern independence of RD-ASEP test points correlation assessment, gearshifting and HEV engine operation, dynamic jump, and low load cruising acceleration determination.
Minutes of a PMP hybrid session held 12 October 2026 at the Palais des Nations in Geneva. Discussion covered amendments to GTR 24 and UN R179 on heavy-duty brake emissions, including new limits for 2030, C-factor measurements, driving modes, brake functions, emission factor calculations, and compliance and conformity of production procedures. Topics included measurement setup, payload factor, test inertia determination methods, inter-laboratory study status with data from 5 labs, and removal of square brackets from GTR text. The group reviewed brake particle emission work from Phase 2 of the DfT programme and preliminary results from a calibration materials inter-laboratory exercise involving 8 labs, recommending continued use of emery oil for annual validation at 23 nm.
Meeting minutes documenting PMP discussions on amendments to Brakes GTR 24 and UN R179, including TF3a layout and testing topics, TF3b vehicles limited speed work, TF3c brake replacement parts with a new UNR to be introduced, and TF4 electromechanical brakes with no further progress. GTR and UNR informal documents on HD brakes were presented with trailers removed from scope, open points on PM Emission Factor units, caliper position, test input parameters, and cooling air flow value addressed, and a 3-month delay in round robin testing reported.
General guidance for drafting the baseline document on artificial intelligence in the automotive sector. The document emphasizes focusing revision on green text in AI-11-03, using change requests for substantive modifications processed during IWG plenary sessions, and integrating successful requests into a single master document. Four sections are addressed: Introduction (AAPC lead) to clarify purpose and scope; AI Uses & Benefits (OICA/CLEPA lead) to provide intuitive understanding and define terms; Risks (modifications by change request); and Risk Management (China and EME leads) to clarify operationalization in certification regimes while maintaining agreement-neutral, conceptual language at reference document level, avoiding prescriptive guidance.
