Proposal to insert new clauses to section 8 of the Consolidated Resolution on the Construction of Vehicles (R.E.3) to add provisions 8.40.1. through 8.40.9. establishing requirements for:

• Periodic technical inspection of vehicles, including verification of proper condition and functionality through testing equipment, electronic vehicle interface, scan-tools and manual/visual inspection,
• access to in-vehicle data without changing approved vehicle design or affecting software integrity, functionality of installed safety systems, and cyber security measures,
• manufacturer provision of technical information for testing equipment, electronic vehicle interface, scan-tools and methods,
• vehicle construction providing access to Diagnostic Trouble Code with regard to identify failure of vehicle, equipment and parts,
• definition of failure,
• requirement that Diagnostic Trouble Code be accessible by scan-tools compliant with international standards without manufacturer-specific, user-specific, or tool-specific restrictions,
• cyber security measures not affected,
• application limited to authorized test centers and workshops.

Proposal to amend paragraph AI to introduce a link between existing text in Part A and new text in Part C regarding vehicle transformations, and insert new Part C providing guidance for the application of UN Regulation No. 155 to transformed vehicles. The proposal adds section 6 clarifying that the requirement for the Certificate of Compliance and type approval to be issued by the same Approval Authority applies only within the scope of the type approval granted to the manufacturer concerned, and does not restrict another manufacturer from obtaining a separate type approval and associated Certificate of Compliance from the responsible Approval Authority.

Summary of “Euro NCAP Technical Bulletin CA 101 – Crash Avoidance” for consideration in the context of UN R152.

GB 39901:2025 establishes technical requirements and testing methods for advanced emergency braking systems of vehicles of categories M₁ and N₁, based on UN Regulation No. 152, 02 series of amendments and China’s road accident data. Performance requirements cover collision warning and emergency braking for vehicle, child pedestrian, bicyclist, and powered two-wheeler targets, with car-to-car test speeds extended to 80 km/h for M₁ vehicles. The standard includes general requirements, functional safety, electromagnetic compatibility, robustness, false response testing, and optional simulation testing. Night-time scenarios were tested but not adopted as mandatory requirements pending international consensus on test methods.

Analysis of pedestrian accident data from the GIDAS database (accident years 2005 onwards) comparing day and night situations across crossing and along-carriageway scenarios. Night situations show higher fatality rates than day situations. Data presented for crossing scenarios with and without obstruction, at junctions, and along straight roads, with documented cases from pure car-to-pedestrian constellations.

Draft agenda for the Informal working group on Advanced Emergency Braking System meeting 24–25 September 2026. Welcome and Introduction. Approval of the agenda and previous meeting report (AEBS2-02-03). Confirmation of TOR of this informal working group (document GRVA-24-14/Rev.2). Accidentology: share accident data from other CP. Review of existing regulation, technologies and state of the art. Draft state-of-the-art performance requirements for collision scenarios involving pedestrians at night. Other business. List of action items and next meetings. 4th IWG: 2–4 November 2026 in Tokyo.

Presentation of traffic accident data for car-to-pedestrian collisions occurring at night in Japan. Approximately 65 to 70 per cent of traffic accidents for car to pedestrian in Japan occur at night-time. The data cover the 10-year period from 2015 to 2024 and analyse obstruction, pedestrian direction of crossing, collision point, walking speed, and age. Seventy per cent of pedestrians cross from the right at night. Accidents involving children aged 12 and under are extremely rare. Vehicle speeds range from 30 km/h to 60 km/h without obstruction and 40 km/h to 50 km/h with obstruction. The proportion of passenger cars equipped with AEBS night-time is approximately half.

Japan presents the current status of Advanced Emergency Braking System (AEBS) testing for passenger vehicles in night-time conditions under the Japan New Car Assessment Program (JNCAP). The document describes test procedures for car-to-pedestrian scenarios, including car-to-pedestrian farside (CPF) and car-to-pedestrian farside obstructed (CPFO) scenarios, conducted with and without street lighting. Test speeds range from 30 to 60 km/h. Test conditions specify tolerances for vehicle velocity, pedestrian target velocity, lateral position, collision point, yaw rate, steering angular velocity, and braking temperature.

The document describes a project to identify Advanced Emergency Braking Systems (AEBS) performance gaps by analysing real-world collision data from UK national research and police databases. The study characterised collision cases against the requirements of UN Regulation No. 152, using STATS19 and RAIDS data sources. Cases were filtered for eligibility, then scored against current test scenarios using weighted collision characteristics including subject vehicle speed, target vehicle speed, relative speed, ambient light, and overlap. Results indicate the coverage provided by relevant test scenarios and identify which characteristics may address gaps in AEBS operational performance.

Minutes of the eleventh meeting of the IWG on EV/HFCV Retrofit Systems held on 9 September 2026. The group adopted the provisional agenda and reviewed the draft UN Regulation on EV/HFCV retrofit systems. Key discussions addressed the regulatory concept for approval of the Electric Powertrain Retrofit System combined with installation requirements and vehicle testing, vehicle scope including possible exclusion of older vehicles and those subject to UN Regulations Nos. 155 and 156, and confirmation that HFCV provisions would remain as placeholders for later development. The updated working document will be circulated before submission to GRPE in October 2026.

Final draft proposal to:

• Amend para. 1.4. to clarify recording obligations for data elements when sensors lack design capability to meet format requirements,
• Amend para. 2.20. to define engine throttle as driver-requested acceleration torque demand,
• Amend para. 2.73. to define trigger activated,
• Amend para. 5.4.3. to clarify crash test requirements and specify data retrievability after impacts of severity levels set by UN Regulations Nos. 94, 95 or 137,
• Insert new paras. 12.12. through 12.17. establishing transitional provisions with dates from entry into force through 1 September 2035,
• Amend Annex 4 Table 1 to add data elements including occupant size classification, vulnerable road user secondary safety system warning indicator status, and advanced driver distraction warning time since warning issued, with modified recording intervals, sample rates, and ranges for existing data elements.

Minutes of the 48th SG-EDR conference call meeting held 15-16 September 2026. The group conducted final review of official documents for UN R160 and UN R169, reaching agreement on multiple technical specifications: DDAW recording duration of 60 minutes (bracketed for GRSG consideration), DCAS duration of 1000 seconds and 10 warnings, LDWS and data element frequencies of 4 Hz and 10 Hz respectively, yaw rate frequency increased to 10 Hz, and airbag warning lamp adjustments. Transitional provisions set for 2030 and 2035. EDR Step 3 workstream planning identified topics including triggering sensitivity, data elements, L-category vehicles, and data survivability. Governance discussion noted DSSAD separation under IWG ADS2, with EDR work continuing under potential new taskforce structure.

Document confirms homework points for consideration of night-time requirements for car-to-pedestrian scenarios in UN R152. Topics include vehicle categories M₁ and N₁, crossing and longitudinal collision types, farside/nearside pedestrian direction, pedestrian walking speed of 5 km/h, lighting conditions, collision points at 25%, 50%, and 75%, dummy types, vehicle activation speeds of 30–60 km/h without obstruction and 40–50 km/h with obstruction, and speed reduction. Daytime requirements discussion covers car-to-car speed reduction at 80 km/h, collision point revision, and car-to-pedestrian speed reduction review based on current technology.

This regulation establishes uniform approval provisions for Advanced Emergency Braking Systems (AEBS) fitted to motor vehicles of categories M₁ and N₁. The AEBS shall automatically detect imminent forward collisions with vehicles, pedestrians, or bicycles, provide driver warning, and activate vehicle braking to avoid or mitigate collision severity. The system must meet specified performance requirements under defined test conditions for car-to-car, car-to-pedestrian, and car-to-bicycle scenarios. Requirements include collision warning provision, emergency braking of at least 5.0 m/s², active speed ranges, driver interruption capability, deactivation controls, and warning indications. Testing procedures, vehicle conditions, target specifications, and virtual testing provisions are specified.

Proposal for a new UN Regulation establishing uniform provisions for type approval of Electric Powertrain Retrofit Systems (EPRS) designed for conversion of vehicles of categories M and N to full electric propulsion. The regulation does not apply to vehicles holding approval under UN R155 or UN R156. It sets out requirements for EPRS manufacturers, installers, markings, approval procedures, general and specific technical requirements for retrofit systems, installer authorization and training, documentation to be provided by manufacturers, conformity of production, modification and extension of approvals, and penalties for non-conformity.

Proposal for uniform provisions concerning approval of ADS marker lamps for power-driven vehicles and their trailers, and approval of vehicles with regard to installation of ADS marker lamps. Covers component approval requirements including luminous intensity, colour, and light distribution for front, rear, and side ADS marker lamps, and vehicle installation requirements including position, geometric visibility, electrical connections, and conformity of production procedures.

Report of the 34th meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements held on 22 September 2026. The group reviewed a draft proposal hybrid regulation for ADS marker lamp after an editorial meeting, going through the entire document and deleting unnecessary comments. Para. 9.26 regarding substitution will be placed in square brackets for further discussion at GRE, as Japan opposes it due to lack of scientific evidence. Paragraphs 10.6.2. to 10.6.5. regarding reciprocal incorporation with direction indicators were reworked, and justification text requires further development for the formal proposal. Document AVSR-34-02 will be sent to GRE-95 as an informal document.

Proposal to establish uniform provisions for approval of automated driving system (ADS) marker lamps for power-driven vehicles and their trailers, and approval of vehicles with regard to installation of such lamps. The regulation covers component approval requirements including technical specifications, photometric and colorimetric characteristics, light distribution, marking, and conformity of production procedures for Part I; and vehicle type approval requirements including application procedures, general and individual specifications for lamp installation, positioning, geometric visibility, electrical connections, and conformity procedures for Part II.

Draft report of the 33rd meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements held on 7 September 2026. The taskforce discussed ADS marker lamps, including a draft proposal for a hybrid regulation, research results from Korea on V2H communication systems, and a presentation by Japan. Key discussion topics included the allowance for substitution of front position lamps and DRLs by ADS marker lamps, lateral ADS marker lamp signalization for trucks, approval marking labels, and visibility angles for side ADS marker lamps. The taskforce agreed to conduct editorial work on the proposal on 16 September and hold a finalizing meeting on 22 September to prepare an informal document for GRE-95 in October.

Document lists work items for phase 2 of the IWG on Automated Driving Systems, organized by categories: ADS requirements covering Dynamic Driving Task (remote assistance, connectivity, MRC, priority vehicles and road safety agents); interactions between ADS and its user(s) (external HMI, feature activation and deactivation, ADS to ADAS transitions, HMI commonality, resuming control by fallback user); other ADS requirements (software parameter adaptation, DSSAD, non-DDT related tasks); manufacturer requirements (ISMR, safety case, ODD description, leading metric considerations); items affecting UN Regulation or GTR only (separate technical units, communication document, mutual recognition of SMS); and other items (drafting and text improvements, system updates and thresholds, end-to-end AI ADS, items remaining from FRAV/VMAD integration document). Each item identifies lead parties, priority levels, and status.

Table to facilitate consideration of ADS Phase 2 work items and their integration into an ADS2 IWG plan for 2026-2028.

Proposal to clarify para. 5.3.1.14 by replacing ‘end states’ with ‘possible vehicle resting positions’, adding examples of stopped in lane, stopped on shoulder, and stopped in parking spot, removing ‘feature’ from references to the ADS to provide flexibility, and adding requirement for the ADS to select a mitigated risk condition in addition to attempting to reach it.

Change request to amend para. 4.1.6.2. to add a condition that an ADSF-1 shall execute a fallback to an MRC if there is insufficient time available for transition or if it has not been possible to complete a system-initiated deactivation procedure. The revision ensures that in situations where an ADSF-1 does not have time to safely transition to the fallback user, it should fallback to an MRC to avoid having a fallback user that is unprepared and unable to safely take back control.

Proposal to insert new provisions requiring the system to inform users of deactivation procedure initiation and continuation using at least an optical signal and an auditory or haptic signal until completion or termination, escalate the warning using stronger and/or more frequent optical, auditory and/or haptic signals if the user is not re-engaging in the DDT within an expected time after deactivation initiation, maintain the escalated warning while the user is not re-engaging in the DDT, de-escalate the warning when the user is re-engaging in the DDT with sufficient time available for transition, include a haptic component when an immediate user response is required, and require manufacturers choosing to implement warning escalation for user-initiated deactivations to meet the same requirements as system-initiated deactivations.

Agenda for the 29th meeting of the GRSP Task Force on Advanced Vehicle Regulatory Support, scheduled for 5 October 2026. The meeting will address Y-category regulatory framework developments for N1 vehicles, Y-category pedestrian protection under UN R127, UN R42 matters from GRSP-79, Y-category exclusion in UN R134, and other business.
