Proposal to establish a Task Force on Swappable Batteries (TFSB) under GRPE. The task force will review WP.29 regulations and international standards to identify technical requirements for swappable-battery vehicles, focusing on commercial vehicles. It will define vehicle types, clarify vehicle type approval processes, and develop guidance documents. The task force will coordinate with other working groups including GRSP and GRVA, with deliverables expected by October 2027.

TF-AVRS screened UN Regulations for automated vehicle application, focusing on UN R83 and UN R154. Changes enable automated driving system vehicles to perform driver-conducted tests like coast-down tests and roller bench cycles. Modifications include defining vehicle users as drivers or ADS users, adjusting driver mass calculations for X and Y categories, and updating testing mode terminology. TF-AVRS proposes amendments to 17 UN Regulations and seeks guidance on addressing remaining topics.

The Electric Vehicles and the Environment informal group reported on amendments to UN Global Technical Regulations 21, 22, and 25 governing electrified vehicle power, battery durability for light-duty vehicles, and battery durability for heavy-duty vehicles. Proposed changes include revised test methods, boundary conditions, definitions, and alignment with UN Regulation transposition efforts. Future work includes investigating fuel-cell vehicles, charging power curves, and alternative test methods.

Proposal to establish a UN Global Technical Regulation for measuring brake particulate matter and particle number emissions from heavy-duty vehicles. The regulation defines laboratory test procedures using a brake dynamometer and the Worldwide Harmonized Heavy-Duty Vehicles Brake Cycle (WHBC), encompassing 20,353 seconds with 246 brake events across three driving segments. Tests require brake bedding with six WHBC repetitions, followed by emissions measurement. Laboratories must measure PM10 and PM2.5 mass gravimetrically and total and solid particle numbers (TPN10, SPN10) using particle counters. Technical specifications cover brake enclosure design, sampling tunnel configuration, climatic control, instrumentation calibration, and data reporting requirements to ensure reproducible and comparable brake emissions testing across regions.

Proposal to update UN R49 to accommodate Automated Driving Systems (ADS). The supplement modifies definitions, mass calculations, warning systems, and testing procedures to apply to vehicles without human drivers. References to drivers are replaced with “vehicle user” terminology, and special provisions are added for ADS-equipped vehicles in testing and operational requirements.

This Supplement proposes to update UN R154 to accommodate vehicles fitted with Automated Driving Systems (ADS), specifically categories X and Y. Amendments include new definitions for ADS-related terms, modifications to testing procedures, and updated references to vehicle construction standards. Driver-related systems are renamed to account for vehicles without human drivers. Special provisions establish requirements for ADS road load determination and testing modes, while messaging systems are adapted to send signals to ADS instead of or in addition to driver notifications.

Proposal to improve FTIR/QCL Analyser Examination (Para. 9.3.2.8.1, 9.3.2.9.1, 9.3.2.10, Appendices 10–11), including expanding the examination authority to include type-approval authorities and technical services, requiring witnessing of the testing at the instrument manufacturer’s facility, and introducing new appendices providing an examiner template and a verification certificate format, and to permit other techniques for the water quench check (Para. 9.3.2.9.9) to address the adverse effects of H₂O and CO₂ on the CLD’s NOx response and align with the provisions of 40 CFR 1065.750(e)(5).

Proposal to clarify the selection of the wheel load among vehicles with identical brake assemblies for particle emissions testing.

Proposal to correct several outdated references following structural changes to UN R154 (04 series of amendments), including updated appendix numbering in paragraphs 2.47, 2.48, and Annex 5, removal of “worst case certified energy consumption Part B family” from Table 4 reporting requirements, and correction of the vehicle survey reference to reflect its relocation to the 9 Series of amendments to UN R83.

Calibration of measurement equipment to PN10 measures more particles than calibration to PN23. It is therefore logical that compliance with a limit when measured according to PN10 demonstrates compliance with the same limit according to PN23 but this text should be added for legal certainty.

This proposal intends to establish a definition for ‘Hydrogen ICE vehicle’ and the related method for ‘trip validation’

Proposal to introduce optional calculation method for determining f₀ and f₂ road load coefficients, allow measurement of drivetrain delta on component dynamometer, permit evaluation of split runs to increase data base, and enable test vehicle configuration using interpolation method. The calculation method determines final f₀ and f₂ values considering theoretical delta between coast down vehicle and final vehicle. Component dynamometer measurement increases accuracy because not all combinations of road load relevant components can be assembled, allowing all component combinations to be evaluated independently.
