WP.29 | Session 192 | 4-8 Mar 2024

6. The WP.29 Secretary reported that:

AC.2 reviewed the calendar of meetings for 2024. AC.2 noted that GRPE would cancel its May 2024 session and would organize a workshop instead. AC.2 agreed that GRVA organize a formal session on 25 June 2024 during the week of the 193rd session of WP.29 in order to formalise decisions that would be recommended during the informal GRVA session organized in Troy, Michigan, United States of America from 20-25 May 2024. AC.2 recommended WP.29 to support this decision.
AC.2 reviewed the calendar of meetings for 2025. AC.2 welcomed the organization of the May 2025 session of GRVA in the premises of ESCAP in Bangkok (Thailand) as an official session and recommended WP.29 to support this decision.
AC.2 discussed the coordination of work on Automated Driving System (ADS). AC.2 recommended to circulate to all subsidiary working parties (GRs) the two informal documents for information: GRVA-18-33 (related to the Regulatory Fitness for ADS) and GRVA-18-34/Rev.1 (related to review of UN vehicle regulations with regards to their relevance for software updates).
AC.2 discussed the collaboration between the Global Forum for Road Traffic Safety, WP.1, and WP.29 on Automated Vehicles and recommended that the WP.29 subsidiary bodies consider WP.29-190-07 during their next sessions.
AC.2 discussed the GR priorities noted in the draft Programme of Work (PoW) 2024 and requested the secretariat to reflect its suggestions e.g. on limiting the number of priorities in a revised version.
AC.2 noted the outcome of the Special session of the Executive Committee of the 1998 Agreement (AC.3), held on 20 December 2023 and noted that the advice by the United Nations competent office was still pending.
AC.2 discussed the extension of the IWG on EVS. AC.2 recommended the extension of its mandate to allow for continuation of the current work.
At the same time, AC.2 also recommended that the formalization of the special interest group on EVS is agreed to work on the amendment to UN Regulation No. 100 (Electric power trained vehicles), based on the result achieved so far by IWG on EVS.
AC.2 noted the withdrawal of ECE/TRANS/WP.29/2024/2 (agenda item 4.6.1) as requested by GRBP and expected an updated version for consideration at the June 2024 sessions of WP.29 and AC.1.
AC.2 approved the participation of the Association of European Wheel Manufacturers (EUWA) and Eurogas under Rule 1(d) of the WP.29 rules of procedures (TRANS/WP.29/690/Rev.2).
AC.2 recommended AC.4 not to convene.

90. For agenda item 4.6.1, WP.29 concurred with the GRBP request to postpone to the June 2024 session consideration of ECE/TRANS/WP.29/2024/2 (Proposal for Supplement 27 to UN Regulation No. 54), with the aim to combine it with another amendment proposal to the same UN Regulation that had been adopted by GRBP in February 2024.
