The Informal Working Group on Prioritization adopted draft terms of reference for submission to AC.2 and WP.29, with endorsement planned for November 2026 and adoption in March 2027. The group discussed amendments to the terms of reference, including proposals by Sweden and the United Kingdom regarding wording and introductory verbs. Document IWG-Prio-02-04 on prioritization was approved for tabling to WP.29 and AC.2, then distribution to each GRX as a new agenda entry to enable WP.29 members to evaluate priorities from a consolidated numbered list.
Meeting report from an intermediate online session of Task Force EDO on 18 September 2026. Discussions covered wording for the safety case in GTR 1 and UN R11, with agreement to use the sentence in square brackets. For power assisted door opening systems, if a suitable maximum opening force value cannot be found, wording similar to UN R107 will be used without specifying a limit value. OICA/CLEPA were asked to prepare transitional provisions including AT and NT dates for submission no later than 2 November. The Task Force ‘Unlock’ will hold a meeting in October. Additional matters included reviewing UN R11 justifications and confirming requirements apply to first row seats only.
Consolidated text of UN R11 with new provisions to address the opening of doors in an emergency (e.g., post crash) marked in bold text.
Proposal to simplify the RD-ASEP SEM assessment method for electric vehicles using the Supplement 11 to UN R51 slope assessment approach, limit factor x between 0.10 and 0.95, apply AVAS as a uniform 66 dB(A) maximum up to 50 km/h, and replace the existing SEM-AVAS term with this revised strategy. The tyre rolling sound curve, acceleration term from UN R51.03 Supplement 11, and AVAS term aligned with UN R138 are applied, while no other SEM parts are used.
Notes from the 19th meeting of the Task Force Data Analysis, a sub-group of IWG RD-ASEP, scheduled for 2 November 2026. The meeting will discuss amendments to RD-ASEP including treatment of AVAS as a component, consideration of L_DYN definitions, a simplified assessment method for electric vehicles, rounding procedures, and temperature correction. Open items for TF-Editing include independence of test points, gear-shifting and HEV engine operation, dynamic jump, and low load cruising acceleration determination.
Minutes from the Task Force on Tyre Abrasion 53rd session held 29 October 2026.
