International reference standards for harmonics and flicker testing define differing applicable supply voltage levels and operating frequencies. CLEPA proposes maintaining baseline requirements for UN R10.08 unchanged, testing according to standardized parameters of reference IEC standards. Contracting Parties with diverging local grid configurations should define tailored national requirements or propose harmonized evaluation methods directly within relevant IEC standard committees, as direct application or mathematical conversion of limits for diverging grids lacks standardized metrological foundation in IEC publications.

Document raises question on the use of a combination of Level I/II immunity tests based on ISO 7637-2:2011 in the 07 series given that the 06 series prescribed Level III.

During IWG-EMC 53rd meeting, Dutch delegation referenced the 2018 Stint accident in proposals to extend UN R10 radiated emissions below 30 MHz and immunity below 20 MHz requirements. Official forensic investigation reports by TNO and Dutch Safety Board ruled out electromagnetic compatibility as a causal factor. The Stint’s drive system was fully immune under UN R10 Annex 6 at 40 V/m. Level-crossing infrastructure fully complied with EN 50121 railway EMC standards. True root causes were mechanical, electrical, and homologation failures including braking deficiencies, electrical throttle flaw, and vehicle instability. OICA recommends rejecting any expansion of UN R10 scope based on this incident.

The agenda includes a roadmap for the 08 series of amendments with proposals from contracting parties and non-governmental organisations, discussion of numerous technical documents covering harmonics, flicker requirements, charging conditions, immunity testing, radiated emissions, and blind spot detection systems. Referenced documents include EMC-52-05, EMC-53-05, EMC-53-10, EMC-53-11/Rev.1 from previous sessions. Subsequent meetings are scheduled online from December 2026 through July 2027, with a face-to-face meeting proposed in November 2027.

Proposal to improve efficiency of test methods by adding a reference to SAE J1349 or applicable local regulations, in addition to UN R85 and ISO 1585, to para. 6.1.2. and para. 6.1.2.1., and delete the requirement for Current integration measurement from para. 5.2.1. The additions provide consistency throughout the regulation and clarify that test results obtained in accordance with applicable local regulations are considered valid. The deletion removes an inconsistency whereby only Current integration measurement specifies a frequency of 20 Hz, while other items specify at least 10 Hz, and eliminates inapplicable wording carried over from UN R154.

Proposal to:

• Amend para. 2.1.(a) to include fuel cell electric vehicles that have more than one propulsion energy converter,
• Add fuel cell electric vehicle preparation requirements to para. 6.3. requiring run-in in accordance with manufacturers recommendations and at least 300 km of fuel cell run-in with hydrogen refueled in accordance with manufacturers recommendations,
• Amend para. 6.5. to include FCEVs in initial REESS charge requirements,
• Amend para. 6.8.1. to include fuel cell temperature in operational metrics to be monitored and recorded throughout the test,
• Retitle para. 2.6. as Fuel cell architectures, and add paras. 2.6.1., 2.6.2., and 2.6.3. specifying power determination reference points and test procedures for fuel cell architectures.

Japan proposes to add a specific requirement for vehicle speed measurement frequency of 20 Hz in Table A3/1 of Annex 3, consistent with UN R154; revise para. 2.4 to clarify that both constant and transient cycles test methods are permitted; delete redundant text from para. 2.4.1 regarding test cycle requirements; and delete from para. 5.1 the requirement that resolution and method for SOCE availability be determined in agreement with authorities, as these are already specified.

Minutes from the 27th meeting of GRSP TF on AVRS held Wednesday 1st July 2026 online. The agenda and previous minutes were approved. EC reported from June WP.29-199 TF Expert FADS and presented WP.29-199-19. GRSP TF AVRS must complete crashworthiness regulation for Category Y and Pedestrian Protection R127, GRE TF AVSR ADS marker lamps, GRE IWG EMC refinements for ADS in 10R08, and GRPE TF AVRS amendments to UN Regulation No. 154. Regarding amendment proposals to UN Regulations Nos. 35 (ECE/TRANS/WP.29/2026/104) and 68 (ECE/TRANS/WP.29/2026/146), AC.1 postponed voting to the next session due to required quorum not being attained. EC presented updates on Y-category regulatory framework for N₁, Y-category Pedestrian Protection UN Reg 127, and UN Regulation No. 42 and 134. Next meetings scheduled 4th September, 5th October, week 4, 24th November or 1st December, and 7–11 December.

The UN IWG on Cyber Security and OTA issues held its 39th session on 3 September 2026. The provisional agenda (TFCS-38-01/Rev.3) and minutes from the 38th session (TFCS-38-13) were adopted. Regarding R155 amendments: multistage vehicle proposals (GRVA/2026/28, GRVA/2026/29, TFCS-39-08) will be submitted as informal documents with a merged paragraph; component approval proposals (TFCS-39-04) had STU references removed and discussion continues; remote operation for ADS proposals were not discussed but participants are invited to consider a general refresh of Annex 5. RXWIN application proposals (TFCS-39-05, TFCS-39-06, TFCS-39-07, TFCS-39-08, TFCS-39-09, TFCS-39-10, TFCS-39-11, TFCS-39-12) were presented; items 1, 4, and 6 were agreed, item 5 was agreed in principle, and items 2 and 3 regarding R155 and R157 applicability require revised wording. Netherlands expressed concerns about vehicle discontinuation and multiple type approvals. Administrative provisions regarding Type Approval Authority for CSMS/SUMS (GRVA/2026/30, TFCS-39-02, TFCS-39-07) were discussed without consensus. Out-of-scope vehicle approvals (TFCS-38-03) discussion was deferred to a separate workshop. Two informal documents will be provided to GRVA.

This document provides background material for an IWG EqOP workshop scheduled for November 2026 in Tokyo to draft conceptual ideas for assessing robustness of vehicles in frontal crashes using a holistic approach complementing current ATD-based requirements. The workshop aims to protect occupants of varying body height, weight, shape, and seating position by maintaining structural integrity and effective safety systems. Two sessions are planned: identifying issues needing solutions through field data and EqOP priorities from GRSP-78-07, and reviewing regulatory solutions including current regulations R16, R94, and R137, with consideration of ATD and HBM roles.

A study of 24 professional truck drivers investigated how drowsiness develops during real-road driving to test a DDAW system. At night, 17 of 24 drivers reached a KSS level of 8, with average time to reach KSS 8 being 56 minutes. Ten drivers chose to stop or were requested to stop in the sleep-deprived condition. A DDAW recording window of 600 s would fail to capture information relevant to the EDR, whereas time windows of up to one hour could provide important indications of increased driver fatigue.

Proposals for EDR Step 3:

• Improved triggering to increase detection rate of vehicle-to-vulnerable road user collisions and low-severity vehicle-to-vehicle collisions by considering delta-v and jerk-based trigger thresholds and developing updated triggering thresholds,
• Overwriting and multi-event issues by reviewing crash reconstruction experiences and developing updated requirements on overlapping events and overwriting,
• Data elements and formats to improve meaningfulness and close gaps by considering new data elements, modifications to data element format specifications, deviating recording duration, and focus on functions compared to specific systems,
• EDR for vehicles of category L₁–L₇ to establish relevant EDR requirements by understanding specificities of vehicles of category L₁–L₇ and developing triggering conditions, events, data elements, and survivability requirements.

For vehicles equipped with an Automated Driving System, it shall be possible to retrieve DSSAD time-stamp data elements specified under paragraph 5.2. of Annex 8 of UN Regulation No. 185 recorded within at least the last 30 seconds prior to triggering of the respective EDR event, regardless of whether the DSSAD and the EDR are implemented as a single system or as separate systems. The time-stamp data elements retrievable from the DSSAD shall include the record for the last activation or deactivation of the feature used at the time of the event within the same power cycle. The data elements shall be retrievable in the format specified in Annex 8 of UN Regulation No. 185, though DSSAD location data may be omitted and dates and times recorded may be replaced with information representing the time elapsed between the recording of each DSSAD data element and the triggering of the EDR.

Proposal to clarify that the EDR volatile memory buffer for last stop trigger activation shall accommodate data related to at least five different stops to be overwritten on a first-in first-out basis, and that data for the most recent stops shall be written to non-volatile memory in a way that does not interfere with the event record related to any other trigger of paragraph 5.3.1.

The document discusses amendments to UN R149 regarding road illumination device requirements. Illuminance and light intensity requirements have been amended multiple times over 16 years. The basis for type approval was adapted to 13.2 volts, increasing required values by approximately 40 per cent. In the 01 series, maximum values at 50L increased by a factor of 4 to improve visibility and pedestrian recognition. On dual carriageways, headlamp illuminance should exceed 8 lx@25m in point E50R/L and 16 lx@25m in point E75R. On motorways, E75R should exceed 36 lx@25m with half those values in E50L. However, increased light intensity increases glare risk for oncoming vehicles, particularly with levelling changes due to load.

The agenda includes adoption of the coordination and organization of work with reference to GRPE-92-14, EV/HFCV-02-02, GRPE-93-22-Rev.1, GRSP-78-17, GRVA-25-19, WP.29-199-16, and other documents, electrical safety review, braking, EMC, power determination and battery range, UN draft discussion, and any other business, with a next meeting scheduled for 8th October online.

The Informal Working Group on EV/HFCV Retrofit Systems held its tenth meeting on 2nd July 2026 in Brussels. The group reviewed progress reports presented to WP.29 Working Parties, referencing GRPE-92-14, GRPE-93-22-Rev.1, GRSP-78-17, GRVA-24-07, GRPE-94-06, and GRVA-25-19. Electrical safety will be reviewed later pending clarification on UN Regulation No. 100. The group excluded UN Regulation No. 155 from draft requirements to avoid cybersecurity complications. Braking requirements for retrofitted vehicles and applicability of UN Regulation No. 13/13-H require further assessment. Further coordination with the EMC Informal Working Group is required. The group distinguished battery range requirements for light-duty vehicles from heavy-duty vehicles.

Proposal for a task force to conduct discussions for drafting the regulation to incorporate the Euro 4-level requirements of UN GTR No. 2 into UN R40. Malaysia and Japan will serve as co-chairs. The Task Force shall review the Euro 4 level requirements and any relevant provisions of UN GTR No. 2 and assess their suitability for transposition into UN R40 under the 1958 Agreement framework. The Task Force shall develop draft regulatory text covering test procedures and test conditions, pollutant limit values and related technical parameters, reference fuels and associated testing requirements, administrative and type approval provisions, and transitional provisions and entry-into-force considerations. Target for submission of informal document for draft UN R40-03 is 96th GRPE scheduled in April 2027.

Draft text for a new UN Regulation on crashworthiness of vehicles of category N₁Y, including comments from France:

• Amend paragraphs 0.2.1., 2.4., 5.1., 5.2., 6.3.1., and Annex 3,
• Insert paragraphs 2.5., 2.6., 5.2.4., 5.2.4.1., 5.2.4.2., 5.2.4.3., 6.3.3., and 6.3.3.1.,
• Update annexes with test procedures for frontal, lateral, and rear-end collision and hydrogen fuel system integrity assessment post-crash for vehicles of category N₁Y, to ensure protection of fuel system integrity, protection against electrical shock from rechargeable energy storage systems, and vehicle crash compatibility in frontal, rear-end, and lateral collisions.

The Task Force on Lamps Under Parked Conditions will hold its 12th session as a hybrid meeting in Tokyo on 11 September 2026. The agenda includes discussion of Terms of Reference to modify the timeline, continuation of questionnaire discussion, and proposal for modification of UN R48 regarding lamp test modes and Energy Indicators for M₁ and N₁ vehicle categories. The session will also address follow-up and action items, review of existing Regulations and Standards, any other business, and confirmation of the next meeting.

The agenda includes a review of Terms of Reference from GRBP 78th Session (GRBP-78-13), report of Data Analysis Task Force, review of issues list, review of draft text, and discussion of UN R51 matters. Dates and locations of 2027 meetings will be determined.

The 15th RD-ASEP informal group session will be held at Nissan Technical Center Europe Spain in Barcelona. The venue is located 11 minutes walk from Mercabarna Metro Station Line 9S. Participants should make hotel reservations independently; options include areas near metro line L9S or city center near metro line L5, which connects with L9S. Participants must provide last name, first name, phone number, company name, and email in advance.

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:

• Transposition of UN-GTR 2 into UN R40 based on WP.29/2026/24 02 series amendments,
• Feedback from the previous session consolidated in EPPR-74-09-Rev.2,
• Maximum power determination discussions referencing prior documentation,
• Battery electric vehicle range determination standardization including SAE J2982 procedures,
• Deterioration factors in GTR 23 durability using EPPR-56-04, EPPR-65-04Rev.1, and EPPR-65-05 analyses.

Proposal to insert a new Introduction section containing provisions for vehicles of categories X and Y, amend the Scope to include vehicles of categories X and Y with specific exemptions based on the “R” point or front structural geometry, amend definitions of “Bonnet rear reference line,” “Front structure,” “Normal ride attitude,” “Side reference line,” “Windscreen test area,” and “Cowl monitoring area” to address vehicles of categories X and Y, and amend paragraph 5.3.1.2. regarding Automated Riding Height Suspension System engagement conditions. Changes compared to document ECE/TRANS/WP.29/2026/53 are indicated by red markup.

Analysis examined 14 cases in Japan where child fatalities occurred after children were left unattended in passenger vehicles of category M₁ and N₁ between January 1984 and April 2025. Indirect sensing could potentially have generated an alert in 13 cases, while direct sensing could potentially have generated an alert in 5 cases. Based on these findings, retaining indirect sensing as an option for UNR is proposed.

Proposal to renumber paragraph 5.8.4.2. as paragraph 5.8.4.3., insert new paragraph 5.8.4.2. requiring controls of electric side windows adjacent to the front seat row to be within reach and directly accessible, insert new paragraphs 5.8.8. and 5.8.8.1. to 5.8.8.2. requiring electric side windows of the front seat row to function for at least 2 minutes during vehicle submergence, and insert new Annex 11 prescribing submergence test procedures including container-based test, slope-entry test, and alternative test methods to demonstrate window opening capability under water.

Working draft proposal to:

• Amend paragraph 1.1. to include application to evacuation of occupants in emergency event
• Amend the definition of child safety lock system in paragraph 2.7.1. to specify prevention of unlatching when interior latch release control is activated and describe normal locked/unlocked logic when inactive,
• Amend the definition of full locking system in paragraph 2.7.2. to refer to interior latch release control,
• Amend the definition of door closure warning system in paragraph 2.9. to replace ignition with master control switch,
• Insert new paragraphs 2.30. to 2.38. defining latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• Insert new paragraph 5.4. establishing requirements for exterior and interior door operation including latch release controls, door handles, and unlocking means,
• Amend paragraphs 6.3.1. to 6.3.2. to address exterior and interior locking devices and full locking systems with reference to master control switch deactivation and alarm or acoustic warning provisions,
• Insert new paragraph 6.4. prescribing intuitive operation of latch release controls and door handles, requirements for power-assisted systems to function after power loss for 60 minutes, and door handle design for opening after power loss,
• Insert new paragraph 7.3. requiring testing of power-assisted latch release controls and door opening systems in accordance with Annex 7,
• Insert new Annex 7 establishing a power loss test procedure to verify door opening functionality from interior and exterior following main power supply disconnection, with 60-minute wait before testing and door opening completion required within 80 minutes after power disconnection based on GRSP-78-20/Rev.1 and GRSP-78-48.

Discussions to amend GTR 1 to require doors providing direct access for occupants to be equipped with an intuitively accessible exterior latch release control or alternatively in close vicinity to the door. The document notes that “intuitive,” “discoverable,” and “in close vicinity” are subjective terms difficult to assess objectively. It suggests defining these terms through objective criteria such as untrained first-time user performance testing within a specified timeframe, standardized ISO symbols, defined proximity zones relative to the door, and requirements balancing accessibility against inadvertent operation risks.

Proposals developed during the EDO session to:

• Amend para. 1.1. to include application to evacuation of occupants in emergency events,
• amend definitions of child safety lock system, full locking system, and door closure warning system,
• insert new definitions of latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• insert new para. 5.4. establishing requirements for exterior and interior door operation including latch release controls and door handles,
• amend para. 6.3.1. to reference exterior latch release control and insert para. 6.3.1.1. requiring full locking systems to activate only when vehicle master control switch is deactivated with specified measures,
• amend para. 6.3.2. for side rear doors,
• insert new para. 6.4. establishing requirements for intuitive operation of latch release controls and door handles, power-assisted systems capability after 60-minute power loss, and unobstructed positioning,
• insert new para. 7.3. requiring testing in accordance with Annex 7,
• insert new Annex 7 establishing power loss test procedures for interior and exterior door opening after main power supply disconnection.

The document addresses Part C verification of virtual distance for heavy-duty vehicle batteries. OICA reports pilot phase results from Volvo Group and Daimler Truck AG testing measurement procedures and accuracy under driving and stationary conditions. Key findings show measurement accuracy decreases significantly at lower power levels, with deviations of 0.3% to 4% at higher power. PTO system characteristics influence accuracy; internal PTOs performed better than bodybuilder-installed units. The document identifies challenges including formula correction needs, PTO family concept complexity, and proposes further testing before finalizing Part C requirements.

Proposal to amend footnote 25 to reduce the maximum number of recorded DCAS warnings from 15 to 10 per current ignition cycle. The justification presented cites data burden reduction while retaining information about habitual driver disengagement patterns. Supporting documentation references two autopilot collision cases—Florida 2016 and California 2018—where recorded warnings within existing data retention periods would have revealed repeated disengagement that current recording parameters miss, demonstrating that 10 warnings combined with extended recording duration enables identification of ineffective warning strategies.

Proposal to establish a submergence test procedure requiring that at least one window per row of seats be capable of being fully opened after a vehicle enters water for occupant escape, with the window operable up to 2 minutes after submergence as designed by the manufacturer, defining container dimensions to accommodate the vehicle without wall or floor contact during the 2-minute period except when fully submerged, permitting open-water test sites provided they comply with test conditions while prohibiting freshwater lakes, reservoirs, and saltwater bodies, requiring the master control switch position allow window operation, specifying unladen kerb mass with measuring apparatus not changing axle reference load by more than 5 per cent, lowering the vehicle into water-filled container at horizontal angle 0–10 degrees with time zero defined as when lowering straps become slack and vehicle floats freely, requiring the vehicle remain in water for 2 minutes from time zero without floor contact until fully submerged, requiring window operation by remote system after 2 minutes with vehicle immersed, and permitting alternative subsystem tests demonstrating window opening functionality under submerged conditions.

The agenda addresses UN GTR 22, UN GTR 21, and UN GTR 25, with discussions on fuel cell vehicle proposals, open items, verification results, alternative test methods, and battery replacement provisions. A reminder notes that UN GTR 25 amendment 2 must be submitted to GRPE-96 by December 2026.

The agenda includes adoption of previous session reports, correction of errors in Regulation 150-01, improvement of direction indicator visibility, rearrangement of lamp provisions in Regulation 48, consistency checks for geometric visibility angles, baseline documents for Regulations 48, 53, 74, and 86, review of transitional provisions, discussion of apparent surface definitions, and submission preparation for GRE-95.

Proposal to insert new paragraphs in Section I defining the background, scope, and technical rationale for emergency door opening provisions addressing power loss scenarios, insert new paragraphs 3.25. to 3.31. in Section II defining terms including “latch release control”, “door handle”, “retractable door handle”, “unlock”, “unlatch”, and “power loss”, insert new para. 4.3. establishing requirements for exterior and interior door operation with intuitively accessible latch release controls and door handles on doors providing direct occupant access, insert new para. 5.4. specifying that latch release controls and door handles shall be intuitive, that power-assisted latch release controls shall remain capable of unlatching doors after power loss for at least 60 minutes through secondary mechanical means, active secondary power supply, or fail-safe systems, that power-assisted latch release and unlocking controls shall similarly remain functional after 60 minutes of power loss, that power-assisted door opening systems shall remain manually openable after power loss, that door handles including retractable door handles shall provide accessible gripping features to unlatched doors after power loss, and that unlocking means and latch release controls shall be unobstructed, directly visible, and not located in storage devices or obstructed by interior components, and insert new Annex 6 specifying test procedures for interior and exterior door operation after power loss, including vehicle preparation steps, 60-minute waiting periods, and opening procedures to be completed within 10 minutes with up to five cycles per door.

Proposal to improve the readability of the text by using only the wording “run flat tyre”, mentioning the alternative wording “ self supporting tyre” in a note.

This document proposes establishing a unified global testing method for determining system power and torque of heavy-duty hybrid electric vehicles (HD-HEV) and heavy-duty plug-in electric vehicles (HD-PEV). The proposal addresses the lack of standardized test methods by recommending hub-coupled dynamometer testing for vehicles with central drive systems and chassis dynamometer testing for other configurations. Testing should measure 30-minute continuous maximum power and torque under thermal equilibrium conditions. The document includes technical data from battery energy distribution analysis and recommends China lead formulation of this standard using chassis dynamometer verification.

Under GTR 25, a feasibility assessment proposes introducing a 5-year mid-term performance requirement threshold together with corresponding mileage and energy-throughput limits as an intermediate verification checkpoint for battery degradation. Based on analysis of State-of-Health data from vehicles with 5-year life and mileage ranging from 250,000 km to 350,000 km, the MPR value is set at 75%, which can cover 98% battery-durability performance. Specific mileage and energy-throughput limits are established for vehicle categories M₂, M₃, N₂, and N₃.

GTR 25 establishes alternative test and verification methods for heavy-duty vehicle energy consumption. China released test method GB/T 18386.2-2022 based on chassis dynamometers using continuous cycle and shortened methods. Test conditions include temperature of 25°C ± 5°C, initial battery SOC of 20%, and pre-conditioning soak and charge for minimum 6 hours and maximum 36 hours. The torque meter method measures road load without disabling regenerative braking, achieving resistance matching within 5% error. Test verification includes vehicle selection across mileage groups 0, 200,000, 400,000, and 600,000 km, with on-board data collection and sensor accuracy consistency analysis post-durability.

China introduces an assessment of low State of Charge Energy requirements for M-type vehicles using data from city buses and coaches. At low SOCE levels, available energy is reduced, requiring increased initial battery energy capacity to meet customer driving range expectations, leading to higher purchase costs and vehicle weight. China provides reasons supporting SOCE performance targets at an 8-year timeframe, including significant differences in vehicle types, operating conditions, business models, and battery specifications that vary by vehicle type, making uniform standards inefficient.

Proposal to revise the weight threshold of M₃ vehicle category from 7.5 tonnes to 12 tonnes, split N-type trucks into three categories with light-duty trucks below 5 tonnes, medium-duty trucks above 5 tonnes and N₃ below 18 tonnes, and heavy-duty trucks above 18 tonnes, adjust year and mileage limits for N₂, N₃ medium-duty trucks to 8 years or 500,000 km, and establish energy throughput requirements: M₂ 120,000 kWh, M₃≤12t 300,000 kWh, M₃>12t 500,000 kWh, N₂≤5t 200,000 kWh, N₂>5t, N₃≤18t 400,000 kWh, N₃>18t 1,200,000 kWh.

HWT-PTI held meetings on 8 July, 13 August, and 19 August, with further meetings planned for 28 September, 3 November, and 24 November 2026. Work focuses on three items: revised wording for neutral state of passing beam under discussion, cut-off and kink point commenting on UN R149 Annex 5 and 6, and provision for PTI awaiting outcomes of earlier work items.

The 78th session of the GRE Informal Working Group on Simplification of UN Lighting and Light-Signalling Regulations was held in Brussels, 10-12 June 2026. SLR decided not to include a new Part 7 on Colour-fastness in Annex 6 to Regulation 150-01 and will submit a consolidated correction proposal to GRE-95. Discussion on apparent surface definitions and single lamp distance requirements will resume at SLR-79, with wider consideration of related topics including glare and direction indicator visibility. Baseline documents for Regulations 48, 53, 74, and 86 were reviewed and updated versions will be prepared for the next session. The next SLR meeting will be held in Tokyo on 7-11 September 2026.

This document discusses single lamp distance requirements in context of Apparent Surface simplification pursuant to discussions with Contracting Parties. The current 75mm separation value was not based on studies but on considerations. A 1999 IENGF Milano study concluded that larger distances are acceptable for symmetric constellations, with AFS lighting units spaced up to 200mm. A minimum 600mm separation is mandatory if right and left mounted functional unit identification is required. No evidence of increased accident risk, misidentification of signal, reduced conspicuity, or regulatory enforcement issues from current single lamp separation distances exists. The simplified CAD-based Apparent Surface concept will be based on light emitting surface with clear outer lens disregarded. GTB suspended work on this topic due to insufficient consensus and difficult stakeholder alignment, pending additional information on single lamp separation distance.

Japan submitted comments on RXSWIN assignment at the 38th CS/OTA IWG. Q.1 asks whether, when a type approval is extended from UN R156-00 to UN R156-01, RXSWIN may be assigned at extension time, and if a UN Regulation refers to RE.3 Annex 7 through a supplementary amendment after UN R156-01 transitional provisions become applicable, whether RXSWIN is assigned at that time. Q.2 asks whether Approval Authorities other than the Authority granting approval are expected to have access to the OEM’s Auditable Register, as access information appears provided only to the Approval Authority concerned through paragraph 9.5.2. Q.3 asks whether software updates affecting type approval can be performed under Regulations that do not reference RE.3 Annex 7.

Proposal to amend para. 7.2.1.2.2. to delete, in cases where RXSWINs are not held on the vehicle, the requirement that the manufacturer shall declare the software version(s) of the vehicle or single ECUs with the connection to the relevant type approvals to the Approval Authority and that this declaration shall be updated each time the declared software version(s) is updated, and add that the link between the software version(s) and the RXSWINs shall be declared.

Proposal to insert new paras. 27 and 28 in Part C Guidance for the application of UN Regulation No. 155 to transformed vehicles. Para. 27 states the requirement that the Certificate of Compliance and type approval are issued by the same Approval Authority applies only within the scope of the type approval granted to the manufacturer concerned. Para. 28 states where a vehicle manufacturer modifies a vehicle with existing type approval and applies for new type approval covering the modification, they need not use the same type approval authority as was used by the original vehicle manufacturer.

OICA, CLEPA, and CLCCR oppose the requirement in GRVA/2026/30 for a single Approval Authority to issue the Certificate of Compliance for CSMS/SUMS and vehicle type approval. They contend the approach would create multiple approvals of the same Management System, imposing administrative burden and creating unresolved legal consequences if a CoC is challenged. The organizations propose adding a new paragraph 5.1.5. instead of paragraph 5.1.3. e) to permit mutual agreement between Approval Authorities, allowing usage of a CoC issued by another Approval Authority, with such agreement documented in type approval documentation.

Proposal to amend GRVA/2026/27, which proposes amendments to UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R139, UN R140, UN R152, UN R156, UN R157, UN R171, UN R175, and UN R178:

• Throughout these regulations, amend references to the Consolidated Resolution on the Construction of Vehicles (R.E.3) as document ECE/TRANS/WP.29/78/Rev.8,
• insert new definitions for Software Identification Numbers referring to R.E.3 Annex 7 para. 2,
• amend requirements for software identification to require manufacturers provide necessary information allowing Technical Services to uniquely identify hardware and software configurations,
• insert new provisions allowing vehicle manufacturers to apply for new approvals differentiating software versions for vehicles already registered in the market from new vehicles,
• amend production discontinuation provisions to clarify production is not considered definitively discontinued if manufacturer intends to obtain subsequent extensions of approval for software updates of registered vehicles,
• insert new items in annexes regarding additional information on software identification and software updates including R_xSWIN identification, whether held on vehicle, how to read if not held on vehicle, and relevant parameters for vehicle identification.

Proposed changes to align RxSWIN provisions with the RxSWIN template adopted through WP.29-197-06, remove the proposed requirement to comply with UN R156/01 or later from R157 and R171, remove amendments to UN R155 as decided by the IWG CS/OTA, apply the RxSWIN amendments also to earlier series of amendments in R13, R13-H, R79, R131, R152, R157, and R171, update references to the latest version of R.E.3, ECE/TRANS/WP.29/78/Rev.8, in earlier series, and correct paragraph references and improve structure in R89, R139, R140, R155, R156, and R171.

The first DETA/IWVTA Workshop was held on 17 June 17 2026 in Flensburg. DETA presentations covered focal points, scope broadening to non-type-approval data, and DETA usage for information sharing. IWVTA presentations addressed expectations, industry concerns about burden, and EU issuance and acceptance. Discussion included UN Regulations equivalence to EU emission regulation, template improvements for Part III, and a proposed Asia workshop.

CLEPA supports the general approach in the current draft UN R for children left in vehicles regulation. Systems shall detect presence of children through a technology neutral approach based on performance requirements. Door-logic based systems have known weaknesses and are insufficient as standalone solutions. Systems shall appropriately address situations where children are unknowingly or knowingly left in vehicles, with suitable test cases covering real-life relevant situations and child restraint system installations. CLEPA proposes replacing references to in-direct plus or direct sensing systems with sensing system throughout the regulation.

Proposal to amend UN Regulation No. 142 to clarify that a maximum speed warning label specifying the lowest value of the maximum speed capability of fitted snow tyres displayed inside the vehicle in a prominent position readily and permanently visible to the driver can be via a permanent physical label or an electronic display, and in case of an electronic display the warning can be shown permanently or when the respective speed limit is approached, reached or exceeded, and to provide that the speed warning label shall not be required for vehicles of categories X and Y equipped with an ADS.

Proposal to amend GRVA/2026/26, based on GRVA-25-18, insert new para. 3.2.2. requiring manufacturers of Automated Lane Keeping Systems active in multiple Contracting Parties to provide summaries of how traffic rules were identified and assessed, specific testing carried out, and a single point of contact, insert new paras. 4.8. to 4.8.6. establishing approval procedures requiring the granting approval authority to inform receiving approval authorities at least 30 days before approval with manufacturer information and safety statements, permit receiving authorities 30 days to provide comments, require disputes to be settled under the 1958 Agreement, and apply these requirements mutatis mutandis to extension approvals, and insert footnotes [Y] and [X] providing for periodic review and specifying contact methods via WP.29/343 online platform or document.

Proposal to insert new para. 3.2.2. requiring manufacturers of Automated Lane Keeping Systems active in multiple Contracting Parties to provide information on traffic rules identification, territory-specific testing, and contact details, insert new paras. 4.8. to 4.8.6. establishing procedures for multi-territory approvals including notification of receiving approval authorities within 30 days, review and dispute resolution processes, and extension requirements, insert footnote [X] specifying communication via UNECE online platform or ECE/TRANS/WP.29/343 document, and insert footnote [Y] noting periodic review by GRVA.

Proposal to insert new para. 3.3. requiring that the use of non-durable protection shields (e.g., non-integral ferrite blocks, aluminium foil) shall be prevented, and if used, shall be duly described in the information document and test report.

Proposal to amend Table 2 in Annex 4, paragraph 4.3. to add “Scanning receiver parameters” as heading and add footnote b to minimum dwell time columns stating the selected dwell time shall, in addition, consider the cycle time of certain vehicle functions, e.g. the wiper system, amend Table 2 in Annex 5, paragraph 4.3. to add “Scanning receiver parameters” as heading and add footnote a with identical language, and amend Annex 6, paragraph 4.1. to add language that the selected dwell time shall, in addition, be sufficient for the observer(s) to assess all related vehicle functions, while also considering the cycle time of certain vehicle functions, e.g., the wiper system.

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.

Proposal to require test reports provided by manufacturers to comply with paragraph 3.3. and to be attached to the test report of the technical service.

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 amend Annexes 11 and 17 to specify an observation time of 2.5 min for quasi-stationary equipment as defined in Table 4 of IEC 61000-3-2, with the equipment operating in the mode expected to produce the maximum total harmonic current under normal operating conditions. Currently, UN R10.07 does not specify an observation time, which may lead to different interpretations of the test method and case-by-case agreement during type approval. Specifying 2.5 min would provide a consistent observation and averaging period for vehicle and ESA type-approval tests without changing existing test conditions, limits, or evaluation method.

The IWG RD-ASEP is developing a mandatory test procedure to assess compliance with paragraph 6.2.3 of UN R51.04, ensuring vehicle noise emissions at various speed, load, and acceleration conditions are linked to vehicle physics without defeat devices. R51.04 RD-ASEP expands testing from full acceleration only to any acceleration position, increases vehicle speed range from 20–80 km/h to 1–100 km/h, adds vehicle performance criteria, requires random test points for approval rather than manufacturer declaration, and can test gears and loads previously unavailable. An updated GRB-68-03 will accompany R51.04. Submission targets include informal draft September 2026 and expected working document adoption February 2028, with TOR extension requested through 2028.

This document requests sound model documentation through a series of questions. Two models are documented: sonROAD18, last updated October 2024, uses more than 10 vehicle classes and describes sound power levels using propulsion noise and rolling noise components with spectral model coefficients, vehicle speed, road gradient corrections, pavement corrections, and air temperature corrections. The reference pavement is ACMR8 with porosity less than 8%. NExUS, last updated 2025, uses two vehicle classes comparing battery electric vehicles and internal combustion engine passenger cars, describing sound power levels using spectral model coefficients, speed, and acceleration parameters. The reference pavement is dense asphalt concrete AC 11 S. Both models use omnidirectional directivity and position sources 0.05 m above road surface.

sonROAD18 is a Swiss road traffic noise emission model based on CNOSSOS-EU formalism, covering more than 10 vehicle categories with speed ranges 20–130 km/h, calibrated using over 700,000 pass-bys from 2015–2017. NExUS is a research model for noise from battery electric and internal combustion engine passenger cars during acceleration in urban scenarios, based on more than 3,000 real drive trajectories recorded in 2024, with speed ranges 0–60 km/h. Both models predict noise emissions via propulsion and rolling noise components using three octave bands.

An improvement intended to increase vehicle robustness in Annex 3 creates more difficulties in RD-ASEP assessment. Small variations in Annex 3 parameters may result in unexpected substantial exceedances in Annex 7. Minimal changes in the calculated tyre share at the anchor point may cause vehicles to fail Annex 7. The regulation should ensure realistic test effort and workload for compliance verification, as current requirements may require up to 180 combinations per type across test tracks, temperatures, driving modes, and tyres.

RD-ASEP includes technical background and vehicle application guidance for Real Driving Additional Sound Emission Provisions under UN R51.03 Supplement 7 Annex 9 for the mandatory monitoring phase between 07/2023 and 06/2024. RD-ASEP, referenced in GRB-68-03, applies to vehicles of category M₁ and N₁ equipped with internal combustion engines and covers engine speeds up to 95% of typical driving in speed ranges applicable to sub-urban conditions. A Sound Expectation Model predicts vehicle sound levels at randomly selected operation conditions by splitting measured pass-by test results into tyre rolling sound, mechanical no-load sound, and dynamic sound components, using reference values from Annex 3 type approval tests with logarithmic functions and parameter table slopes. Compliance assessment allows measured sound to exceed calculated expected sound by not more than 2 dB for maximum two test runs out of fifteen. Model validation with 2024 monitoring database confirms the tyre rolling sound and power train sound models represent well approved tyres and engines, with less than 5 dB typically separating pass-by run results from the limit.

Proposal to add a new example and update text based on discussions by the OPI group aimed at finalizing the GID. The revised text adds that the ADS does not transit to a safe state in accordance with the manufacturers defined response as documented in the safety case, and removes provisions regarding the chosen stop location. The group agreed to further work in the next phase on situations where the chosen stop location could have contributed to a collision involving the ADS vehicle before it has moved from that location.
