Proposal to increase yaw rate recording frequency to 10 Hz. Yaw-rate data recorded at 2 Hz corresponds to one measurement every 500 ms; increasing to 10 Hz provides a measurement every 100 ms, resulting in a fivefold improvement in temporal resolution. This enhancement significantly improves ability to reconstruct pre-crash vehicle dynamics, identify vehicle instability onset and progression, and evaluate Electronic Stability Control functionality. A yaw-rate recording frequency of at least 10 Hz reduces temporal uncertainty from 500 ms to 100 ms and enables more accurate reconstruction of loss-of-control events, vehicle rotation, ESC interventions, and driving dynamical issues.

The agenda includes:

• DDAW system warnings and driver acknowledgement,
• microsleep detection requirements,
• system effectiveness under varied driving conditions and when DCAS is active,
• system functionality where driver occlusions occur,
• drowsiness thresholds for warnings,
• criteria for classifying false negatives,
• test methods,
• specificity and positive predictive value as performance metrics,
• observer-rated drowsiness,
• timing of future meetings.

The agenda includes:

• Coordination and organization of work,
• Pollution emission control in PTI covering PN measurement, NOx measurement, and Euro 7,
• Advanced Driver Assistance Systems and Automated Driving Systems using diagnostic devices for in-vehicle data access,
• Periodical technical inspections of automated vehicles,
• PTI provisions for brakes, lighting devices coordination approval and inspection,
• 1997 Agreement updates,
• Any other business including R.E.1 document from WP.1,
• Next meetings.

The 43rd session of the IWG on PTI convened on 8 May 2026 in Brussels. The group reaffirmed the need to strengthen integration between type approval and in-use inspection per WP.29 Whole-Life Compliance framework (WP.29/2023/89). At least 20 UN Regulations contain incomplete, non-harmonised PTI provisions. The IWG agreed to add “Review of PTI provisions in UN Regulations (1958 Agreement)” to its Action Plan and submit a proposal to WP.29 requesting endorsement. Work on diagnostic tools in PTI and automated vehicles inspection continues. The group reviewed recent amendments to UN Regulations Nos. 13 and 13-H for new braking technologies and identified challenges regarding LED replacement light source inspection.

Document presents automated shuttles as vehicles designed for public transport with autonomy by design, typically featuring fewer than 10 seats and often limited to 50 km/h maximum speed. Shuttles are deployed globally but are incompatible with current UN vehicle categories: category M₁ does not accommodate standing passengers and is incompatible with crashworthiness regulations, while M₂/M₃ Class A construction alignment is prevented by the fewer-than-10-seat threshold. Proposal calls for a workshop organized by the GRSG/GRVA task force on automated vehicle categories to engage stakeholders and confirm need for an international category or class, addressing administrative questions, alignment with M₂/M₃ regulations, seating capacity, dimensions, weight, speed limits, and bidirectionality options.

Proposal for conducting the ADS Active Test Specified in Annex 6 to clarify ADS Active Mode, clarify methods to activate ADS using test equipment or by modifying in-vehicle ADS-related ECU software, clarify test objects for ESA at component-level or system-level, and clarify test methods when ADS cannot be activated in an anechoic chamber, including testing in a non-active state using warning indicators and diagnostic functions, and testing when errors occur upon ADS activation. The proposal defines ADS Active Mode as representative ADS functions remaining operational using sensors whose inputs can be simulated within the anechoic chamber environment, with alternative test methods including application based on ESA or subsystem test results, testing with ADS not activated using steady-state driving conditions with pass/fail criteria verifying no communication errors, ECU malfunction, freeze, shutdown, or ADS system malfunctions occur, and testing with simulated sensor outputs using data from real-world driving or representative driving scenarios.

Proposal to insert a new definition of functional test configuration, amend para. 2.1.1.2. to clarify that test conditions are agreed between manufacturer and technical service and that tables provide guidance which may be extended or amended depending on vehicle characteristics, add tables specifying basic vehicle test conditions for “50 km/h mode,” “Brake mode,” and “Active ADS Mode,” add an alternative “Brake mode” with active ADS for vehicles where braking mode cannot be applied with ADS operational without ADS feature(s) activated, add AECS and AVAS test condition tables, and insert a new table cross-referencing UN Regulations with specific provisions and test configurations to demonstrate compliance with UN R10.

Agenda for the 48th session of the Subgroup on EDR, a hybrid meeting scheduled for 15-16 September 2026 in Berlin. The agenda includes a final review of and potential amendments to official documents to GRSG regarding UN R160 and UN R169, discussion of the need for Step 3 and inventory of potential items for Step 3 workstream with presentations by IWG delegations expected, EDR for ADS, and a list of action items and schedule of future conference call meetings.

Proposal to amend, delete, and insert various provisions throughout a Guidance and Interpretation document on GTR 26 and UN R185 on Automated Driving Systems. The document supplements the proposal to supersede GRVA/2026/24 by providing the changes to the draft text separately from the restructuring and additions of GTR 26 references.

Document presents Korean research on event data recorder (EDR) data survivability in electric vehicles following post-crash fires. Analysis of nine Korean EV fire cases shows EDR data retrieval failed in three cases due to ACU damage in fully burned vehicles, while six cases achieved data retrieval despite water immersion from firefighting. The document proposes water immersion testing to assess EDR data survivability for inclusion in EDR Step 3, referencing international automotive standards for test method development.

Wrap-up of the 21st ADS IWG and 19th GRVA Workshop on ADS Brussels session held 14-17 July 2026. The session discussed and accepted numerous proposals to amend the Guidance Implementation Document (GID) for GTR 26/UNR 185, including modifications to introductory text, safety risk management requirements, reporting provisions for various operational issues, and safety management system guidance. The session also discussed activities for ADS IWG Phase 2 (2026–2029), including remote assistance, ODD description, external HMI, feature activation and deactivation, connectivity, software parameter adaptation, ADS/ADAS transition, DSSAD, ISMR, leading metrics, safety case, text improvement, implementation, system updates, MRC, priority vehicles, STU, and end-to-end technologies.

Status report on the ADS Workshop since the 25th GRVA, covering two meetings held in June and July 2026. Task 3 addressed interpretation and guidelines, with nearly 60 change requests discussed and concluded during the Brussels meeting. Four types of changes were needed to GRVA/2026/24: consolidation of approved changes, addition of GTR version references, revised number formatting, and editorial improvements. Two informal documents are provided for clarity: a clean revision (GRVA-26-09e) and a listing of substantive changes (GRVA-26-09a1e). The workshop seeks GRVA approval for submission to WP.29 in November 2026 for adoption in March 2027. The revision applies alphabetical headings aligned with ADS regulations structure, alphanumeric subheadings for explanations, and deletes consecutive numbering to avoid confusion with GTR and UN R185 paragraph numbers.

Status report on activities of the IWG on CS/OTA since the 25th GRVA session. The IWG reviewed proposals for amendment of UN R155 and its interpretation document for multi-stage vehicles, proposals for approval-authority arrangements and Certificates of Compliance for UN R155 and R156, proposals integrating software identification and update text across several UNRs outlined in RE.3, component and STU approval concepts, and remote operation and automated driving systems. The IWG proposes updating regulatory text and interpretation documents for UN R155, revisions to software identification and update text across several regulations, and revised Terms of Reference for a mandate till November 2029.

The IWG on AEBS held its second meeting virtually on 18 June 2026 and decided to submit ECE/TRANS/WP.29/GRVA/2026/38 for approval, an amendment adding a footnote to clarify that Sufficient nominal Peak Braking Coefficient should be understood as a minimum value. The IWG plans to collect accident data from jurisdictions, existing regulations, technologies, and state-of-the-art performance requirements for collision scenarios involving pedestrians at night. A schedule of future informal meetings is provided through January 2028, with a draft regulation planned for availability by January 2028 and formal submission by September 2028.
