The AEBS IWG held its initial meeting virtually on 22 April with about 50 attendees. Co-Chairs are Germany and Japan; Co-Secretaries are CLEPA and SAE. The IWG is requesting minor changes to its Terms of Reference. A schedule of meetings is planned from September 2026 through September 2028, including informal meetings for input from contracting parties and industry, discussion of requirements for speed reduction in nominal conditions, and investigation of false positives, with a draft regulation document planned for January 2028 and formal submission planned for September 2028.
The document requests guidance on the legal basis for provisions within UN Regulations extending beyond the End-of-Production date and which authority such provisions address. Examples include UN R171 requirements for manufacturers to demonstrate safety management systems to the Type Approval Authority every three years and report annually on Driven Coded Auxiliary System operation until production is discontinued, and UN R155 requirements for Cyber Security Management Systems to apply to the post-production phase when vehicles remain operational but are no longer produced. The document poses an additional question regarding vehicle safety when manufacturers cease operations and cannot fulfill post-deployment safety provisions.
Proposal to address REESS using offboard AC/DC chargers. Some vehicles with REESS use offboard AC/DC chargers, a configuration not described in UN R10. The proposal adds test configurations for vehicles charging through offboard AC/DC chargers to multiple annexes, including flowcharts defining charging mode configurations and specifications for AMN or DC-charging-AN or AN for offboard AC/DC chargers below 60 Vdc. The proposal is based on IWG-EMC-49-12e.
The CS/OTA Task Force held its thirty-seventh session on 21-22 April 2026 by video conference. The group adopted the provisional agenda and minutes from the thirty-sixth session. Discussions addressed proposals for amendments to UN R155 concerning multi-stage vehicle approvals and separate technical units, for which a subworking group was established. Proposals were also considered on type approval authority responsibility for cyber security management systems and remote operation of automated driving systems. The group reviewed cyber and software requirements in the ADS GTR and WP.29/2022/60 as amended by WP.29/2023/87, and discussed application of RXSWIN to UN Regulations, selecting option 2 for presentation to GRVA with R155, R156, and R89 square bracketed. The IWG mandate renewal was discussed, with potential new items including component and STU approval and software numbering proposals.
Draft formal submission (GRSP/2023/xx) for the May 2023 GRSP session to align UN R134 with Phase 2 amendments to GTR 13.
