The amendments update footnotes across documents to reference the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8. The document modifies provisions related to Automated Driving Systems and Advanced Driver Assistance Systems sensors, test mass specifications, logical signal transmission, acoustic characteristics, category definitions, and occupant compartment requirements across multiple regulations.
The agenda includes discussion of Terms of Reference from GRBP-78-13, procedural update from GRB-68-03, Analysis Task Force Report, Editing Task Force Report, R51.04 Issues List Review, draft R51.04 text review, Inside and Outside Boundary Condition discussions, and confirmation of next meeting date and place as August 31–September 1 in Geneva, Switzerland.
The IWG EqOP held its 16th meeting on May 18, 2026, with 40 online participants from Contracting Parties and Industry. The agenda and minutes of the 15th meeting were approved. Three Task Forces—Rear-end assessment, Virtual crash testing, and Frontal impact and restraint systems—are operational with meetings planned in June 2026. A preliminary report to GRSP 79th session was presented and revised. Upcoming meetings include TF3 on June 11, TF4 on June 25, and TF2 on June 29-30. Each Task Force is invited to structure identified topics by prioritizing them and assigning short, medium, and long-term horizons, and to map contributions within the Task Force.
The agenda includes a workshop with two sessions addressing whether UNR17 dynamic testing should be mandatory and updates on ongoing research including CNCAP, Euro NCAP, EvaRID, BioRID, parametric study, and SET, discussion of a potential in-real-life workshop in October at BASt, and determination of the next meeting date.
Current RD-ASEP derives the regulatory level based on the certified value without accounting for margin against regulatory values of the certified value. RD-ASEP additionally regulates partial acceleration, unlike current ASEP which only stipulates full-throttle acceleration. It is proposed that RD-ASEP should take into account a margin against the regulatory values of the certification values, similar to current ASEP, to prevent quiet vehicles such as BEVs from being unfairly deemed NG.
In vehicles with automatic transmissions, upshifts during testing cause SEM expected values to be exceeded. The proposal addresses three cases: vehicles with non-locked gear ratios, vehicles with locked gear ratios, and vehicles with only one gear ratio. For Case 1, such data does not meet conditions in R51-03 Annex 9 “4.5.2. Non-locked transmissions” and require no SEM correction. For Case 2, the proposal adds text to Annex 9 (7), Appendix 1, paragraphs 3.4. and 3.5., permitting substitution of maximum engine speed nMAX(AA-BB)TEST for nBBTEST when the maximum engine speed between AA’ and BB’ exceeds the engine speed at BB’.
54. Mr. Moosong Pyun (Republic of Korea) would no longer attend the GRSG sessions, and the Working Party acknowledged his fruitful contributions to the work and wished him all the best for his future activities.
