China supports establishing a new task force or informal working group on vehicle data security and sees the need for a dedicated UN Regulation or Global Technical Regulation. Work can begin with applicability analysis of existing regulations, gradually establishing the main framework of the standard, the scope of data management, and handling of special cases. China is ready to act as a key contributor, offering typical use cases, design questionnaires based on GB 44497 and GB 44464, delivering terms of reference with other Contracting Parties, and proposing basic framework and specific requirements by February 2028.

OICA-CLEPA-EME comments on German proposal GRVA-25-07 to require the approval authority granting UN R155 or UN R156 type approvals to use CSMS or SUMS certificates signed by the same approval authority. OICA-CLEPA-EME identify that CSMS and SUMS are Management Systems covering entire manufacturer organizations, and mandating the same approval authority for Management Systems certificates and approvals will have significant consequences for original equipment manufacturers typically using multiple approval authorities in homologation. The submission proposes keeping text unchanged to allow different approval authorities for Management Systems certificates and type approval based on voluntary acceptance, implementing wording on information exchange if different approval authorities are involved, and establishing a horizontal approach for Management Systems with mutual recognition aspects considered.

In January 2022, an M₁ passenger vehicle with a detached tyre caused its Anti-lock Braking System to activate, preventing effective braking and resulting in collision with a stationary lorry. The coroner concluded the ABS functioned as intended but created an unsafe scenario by using the fastest rotating wheel as reference speed, and recommended changes to prevent future deaths. The UK proposal to amend UN R13-H would require manufacturers to affirm that strategies to achieve system objectives will not prejudice safe operation of systems under non-fault conditions, including failures of other systems involved in achieving system function such as tyres or wheels, and that documentation be supported by analysis showing how the system will behave upon any fault with bearing on vehicle control, performance, or safety, including faults with other systems involved in achieving system function.

Proposal to amend para. 3.5.1. of Annex 4 to require the manufacturer to demonstrate to the approval authority that effective processes, methodologies and tools are in place, up to date and being followed within the organization to manage the safety and continued compliance throughout the product lifecycle, and to demonstrate to the approval authority at least every three years that the safety management system continues to comply with these requirements.

Proposal to delete paragraph 1.2.6. excluding e-axle trailers with e-axles providing electric propulsion and/or incorporating an electric regenerative braking system from the scope of UN R13, and add definitions of “e-axle,” “e-axle trailer,” “dynamo function,” and “e-trailer”; add special requirements for power-driven vehicles supporting e-trailer operation, e-axle trailers equipped with dynamo function, and e-trailers of category O; add requirements for electric control lines conforming to ISO 11992-2:²⁰²⁷; specify message support and functional compatibility; and add provisions for electric regenerative braking, dynamo function, and propulsion, including parameters such as retarder torque demand priority, propulsion force limits, overriding mode activation at speeds below 15km/h, and vehicle stability function interaction.

Proposal to delete the draft “Reserved” paragraph 5.3.7.2.4.3. in GRVA/2026/18. Reserving paragraph 5.3.7.2.4.3. in the 01 series would mean that the subsequent paragraphs would be out of line with the numbering in the 02 series, making future amendments to UN R171 unnecessarily challenging.

Proposal to amend the original version (GRVA/2026/15), insert para. 5.3.7.2.1.13. to require the manufacturer to describe in the safety concept the system behaviour in case the driver is detected to be disengaged during a manoeuvre; amend the original version and the 01 series (GRVA/2026/15 and GRVA/2026/17), amend para. 3.5.1. of Annex 3 to require the manufacturer to demonstrate to the Type Approval Authority at least every three years that the safety management system continues to comply with requirements; amend the 01 and 02 series (GRVA/2026/17 and WP.29/2026/86), amend para. 2.3.2. of Appendix 2 of Annex 3; amend the 02 series (WP.29/2026/86), amend para. 4.2.5.2.19.2.1. of Annex 4; and amend the original version, 01 series and 02 series (GRVA/2026/15, GRVA/2026/17 and WP.29/2026/86), amend para. 4.2.5.2.14.1.2. of Annex 4 and para. 4.2.5.2.14.2.1. of Annex 4.

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.

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.

Proposal to revise the terms of reference and rules of procedures for the Informal Working Group on Advanced Emergency Braking Systems.

This document consolidates amendments to WP.29/2026/86 by GRVA/2026/14, GRVA-25-46, and GRVA-25-51. It proposes to amend para. 5.5.4.2.8.2., renumber reference to para. 5.3.7.2.1.1.1. to 5.3.7.2.4.10., amend paras. 5.3.7.2.4.2., 5.3.7.2.5.3.1., 5.3.7.2.6.1., 6.4.2., and 7.2.3.1., replace “definitely” with “definitively” in para. 14.2. and Annex 3 paras. 3.1.1.a and 3.1.1.b, insert new para. 16.2.3. effective 1 September 2029, amend Annex 1 para. 6.4., renumber reference in Annex 3 para. 3.5.7., amend Annex 3 Appendix 2 para. 2.3.2., amend text in Annex 4 diagrams at paras. 4.2.5.2.8.1.2., 4.2.5.2.10.1.1., 4.2.5.2.12.1.1., 4.2.5.2.16.1.3., and 4.2.5.2.20.1.3., delete second diagram in para. 4.2.5.2.14.1.2., amend paras. 4.2.5.2.14.2.1. and 4.2.5.2.19.2.1., and delete words in para. 4.2.5.2.19.1.1.

Proposal to modify the specified maximum remote controlled parking operating range from 6 m to 15 m. Large markets including Canada, USA, and China do not regulate maximum remote controlled parking operating range. Remote controlled parking systems exceeding 6 m operating range are already offered in the field. Radio wave-based ranging is inherently inaccurate due to complicated and varying electromagnetic environment in garage and changing orientation of remote device, requiring safety margin integration into product design, which reduces effective usable range below 6 m maximum. Extended range remote controlled parking systems have been used in the field for several years without negative feedback or identified safety threats.

Proposal to amend row 13© of the List of proposed decisions on the documents reviewed during the informal consultations (GRVA-25-04/Rev.2) to specify that GRVA partly included the work on DSSAD within the IWG on ADS remit, with items to be included comprising strategic directions and data elements structured as a separate workstream under an OPI’s coordination, and DSSAD activities related to data format, accessibility, survivability and location becoming part of IWG on EDR activities, with regular online meetings organized to ensure alignment and coordination between the two groups.
