Document presents development of traumatic brain injury risk functions for frontal crash assessment. Brain strain-based injury risk functions were developed using human and non-human primate injury data from experimental studies, calculated using finite element brain models. Kinematics-based injury risk functions were derived by converting strain-based functions using correlations with head rotational kinematics metrics. Injury risk functions were developed for each kinematics-based metric selected through correlation analysis with maximum principal strain in brain tissue.

Status report on the 1998 Agreement global registry and compendium of candidates as of 13 November 2026. The document presents the current state of play for multiple UN GTRs across working parties GRVA, GRSP, GRPE, GRBP, and GRSG, including informal groups, technical sponsors, formal proposals, and draft UN GTR proposals. It details progress on items such as Automated Driving Systems, Electric Vehicle Safety, Equitable Occupant Protection, and various amendments to existing GTRs, with notes on AC.3 endorsements and adoption dates.

Report of the 57th session of the IWG on DETA held on 13 November 2026. The session covered the state of play with 153,000 approvals uploaded by 23 approval authorities, a new DETA software version introducing two-factor authentication and internal mail functionality with migration expected Q1/2027, widening the scope to include a scenario database for automated driving and potential use for sharing technical information on brake emission of non-original parts, amendments to guidelines for UNR155 reflecting changes to the new software version, and plans for a joint IWVTA/DETA workshop on 24 June 2027.

Draft minutes of the 17th meeting of the IWG EqOP held on 14 October 2026. The IWG’s strategic objective is to achieve more equitable and robust occupant protection for a diverse population through inclusive regulations and protection strategies that reduce injury risk below a tolerable threshold for as many occupants as possible. The priorities endorsed by GRSP remain rear impact protection, frontal impact restraint systems, and the assessment of injury types that are currently insufficiently addressed, particularly brain, soft-tissue neck, and lower-extremity injuries. The Chairs reviewed progress of task forces and introduced the proposed theme of the Tokyo workshop: robustness assessment of occupant protection.

The IWG on AI reports on its meetings held since July 2026 and activities including compilation of literature on regulated automotive safety systems using AI, creation of terms and definitions, listing of AI use cases, and work on an AI reference document (latest draft AI-11-03). An AI reference document is scheduled for submission as a formal working document to the June 2027 WP.29 session. Small drafting groups are creating proposed updates for introduction, section 2, and section 4 based on AI-11-03 as baseline.

Feedback from a dedicated workshop on virtual testing as an optional alternative to physical tests in UN Regulations and GTRs. The UK/EC proposal, based on UN R185 ADS, and OICA’s multi-layer approach are presented. Outstanding issues include authority and technical service qualification requirements, definitions and terminology, credibility levels, and uncertainties and safety margins. Participants proposed organizing another workshop in January, establishing a small working group, and requesting written contributions to improve the UK/EC proposal. A new status report is expected during the 201st WP.29 session.

Proposal to amend para. 2.10. to define Residual Rechargeable Electrical Energy Storage System (REESS), amend para. 4.1. of the Annex to specify REESS examples including traction battery, and amend para. 4.2. of the Annex to describe REESS management system with examples of range information, state of charge indicator, and battery thermal control. Amendments apply to both English and Russian versions to eliminate discrepancies and ensure unified approach.

Status report on PTI IWG activities. Work continues on diagnostic devices in PTI (ePTI), with proposal 99% ready. Amendment to Rule 4 for harmonization is in preparation. The group discussed PTI approaches for automated vehicles, reviewed new braking technologies (ETBS and Parking Lock Devices) with draft amendment for Rule 2 underway, and reviewed inspection challenges for LED lighting systems. Implications of new Euro 7 UN Regulations (Nos. 179 and 180) were assessed. Next activities include finalizing ePTI amendment, developing PTI approaches for automated vehicles, drafting amendment on new braking technologies, establishing coordination with GRE on lighting, and consulting relevant groups on inspection methods.
