V2H Communication System Research Results documents a National Project supported by Korea’s Ministry of Land, Infrastructure and Transport conducted across three phases from 2021 to 2026. The research develops vehicle-to-human communication technology for autonomous driving systems through study of communication cases, validation of V2H elements, technology development, and road demonstrations. Survey findings indicate hybrid projection and display approaches achieve 77.7% positive response rates. Trust in autonomous vehicles increased from 24.0% to 41.5%, and safety perception improved from 21.6% to 37.3%. Projection messages reduce pedestrian crossing decision time by 3.64 seconds and ensure 100% crossing decisions with yielding messages across all demographics. Cyan-colored text-based messaging demonstrates superior visibility and user preference ratings of 3.9 to 4.2 on a 5-point scale compared to symbol-based formats.

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 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 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:

• Amend Table 18 row 18,
• Delete Notes to Table 18,
• Amend Table 21 row 13,
• Delete Notes to Table 21,
• Amend Table 23 row 17,
• Amend Table 24 row 13,
• Delete Note 2 to Table 24,
• Amend Table 30 row HV,
• Amend Table 31 row HV.

Proposal to add one line to the Status table introducing new LED light source categories L2 and L3, amend para. 3.3. Group 1 to include categories L2 and L3, amend Annex 3 List of sheets to include L2/1 to 6 and L3/1 to 6, and insert new sheets L2/1 to 6 and L3/1 to 6 specifying essential electrical and photometric characteristics, electrical connector details, bin code resistor values, screen projection requirements, and normalized luminous intensity distribution for both new LED light source categories.

The agenda includes discussion of ADS marker lamps including a draft proposal for a hybrid regulation with remarks from the chairman on document AVSR-31-03/Rev.2 and GTB input consolidated in AVSR-31-02, miscellaneous items, and next steps including a working plan for future activities.

AVSR-33-05 supports requirements for ADS marker lamps to improve social acceptance, facilitate traffic management and enforcement, and ensure smooth emergency vehicle passage. The proposal recommends installation at front and rear with optional side installation, visibility angles equivalent to direction-indicators, continuous illumination without flashing or luminous intensity variation except nighttime dimming, permitted combined use with direction-indicators when the marker lamp turns off on the side where the direction-indicator operates, and applicability to vehicle categories M₁–M₃, N₁–N₃, L₆, L₇, and O when towed by automated driving vehicles.

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.

Presentation of a method of testing for immunity of vehicles of category M₁ to electromagnetic radiation for Blind Spot Detection (BSD)/Blind Spot Information System (BSIS) as defined in the latest series of amendments to UN R151. EMC immunity test criteria for BSD are added.

Proposal to:

• Insert new paras. 12.15. and 12.16. establishing that as from the official date of entry into force of the 09 series of amendments, no Contracting Party applying this UN Regulation shall refuse to grant or refuse to accept an IWVTA issued pursuant to this Regulation as amended by the 09 series of amendments, and that as from 1 September 2027, Contracting Parties applying this Regulation shall not be obliged to accept type approvals to any of the preceding series of amendments, first issued after 1 September 2027,
• Amend Annex 4, Part A, Section I (List of requirements for U-IWVTA) to update the series of amendments for various UN Regulations.

Proposal to amend the General Guidelines for United Nations regulatory procedures and transitional provisions. The document establishes transitional provisions for vehicles, vehicle systems and installation of equipment and parts in new vehicles, including provisions applicable to all series of amendments and specific provisions for the XX series of amendments. Contracting Parties may grant type approvals according to any preceding series and shall continue to grant extensions of existing approvals. As from the official date of entry into force of the XX series, no Contracting Party shall refuse to grant or accept type approvals under the XX series. As from 1 September Date (b), Contracting Parties shall not be obliged to accept type approvals to any preceding series first issued after that date. Until 1 September Date ©, Contracting Parties shall accept type approvals to the XX-1 series first issued before 1 September Date (b). As from 1 September Date ©, Contracting Parties shall not be obliged to accept type approvals issued to any preceding series, subject to special cases permitting continued acceptance of certain equipment/parts or vehicles/vehicle systems.

Proposal to amend para. 3.3.1.2. to specify that the value for ‘a’ in the approval marking shall be at least 5 mm, and add a new para. 3.3.4.4.1. establishing requirements for labels used for additional approval markings specific to the device, including durability for the useful life of the device, legibility, indelible letters and figures, and durable fixing that cannot be removed without destroying or defacing the labels.

Proposal to:

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.

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.

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 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 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.

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.

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.

The session reviewed and adopted the draft agenda and prior meeting minutes. Substantive discussions addressed proposals including harmonics observation time for vehicles and energy storage assemblies (EMC-54-02), conducting automated driving system active tests (EMC-54-03), quality guidance for technical service test reports (EMC-54-04), amending UN R10 based on related regulations (EMC-54-05-Rev.1), minimum dwell time guidance (EMC-54-06), non-durable protection shields clarification (EMC-54-07), and transient immunity (EMC-54-10-Rev.1). The group concluded that further investigation and revised proposals are needed for several items by the December 2026 session. Next meeting: 2–3 December 2026 online.
