No vehicles have received certification under UN R175-00/01. The document lists representative ACPE-equipped vehicle models from various manufacturers and markets, detailing their sensor configurations, target objects, and operation speed ranges. Sensor types include ultrasonic sonar, monocular camera, stereo camera, and milli-wave radar. Target objects are stationary objects and pedestrians. Vehicles exhibit variation in forward and rearward equipment and low-speed braking function inclusion. Performance definitions differ by OEM and are not directly comparable across manufacturers or to UN R175 requirements.

Proposal to clarify components and functions of the ADS and other vehicle systems relevant to meeting the requirements of the regulation (paras. 5.3.1.4.2 (GTR)/7.3.1.4.2 (UNR)). The revised text specifies that other vehicle systems could include shared components or functions such as sensors, map data, and GNSS used for assistance systems or positioning. Information from outside the vehicle may be included if used to meet regulation requirements. The manufacturer could use different diagram types provided information is present, and additional information regarding wireless links could be included.

The change request seeks clarification that “real-time” operational and tactical functions of the DDT, particularly “sensing and perception” and “planning and decision”, could be achieved through real-time sensor inputs alone or through integration of sensor inputs with other contextual information such as map-based data, to aid technical inspectors during testing and assessment of ADS systems.

The ADS regulations (GTR and UNR) include definitions for reporting thresholds based on EDR triggering. Time-series data recording for heavy vehicles under UN R169 requires triggers and trigger thresholds to record data in specified time periods, which may not immediately precede, follow, or coincide with crashes. Last Stop, Safety Systems, and Sudden Deceleration triggers are unreliable crash indications. Sudden Deceleration is too sensitive for storing time-series data over several months. Optional SRS or a new independent trigger alongside Detected Collision offers the only viable possibility for effective time-series data recording.

Australia proposes to amend para. 2.14. to clarify that the nominal Peak Braking Coefficient value is understood to be the minimum value, and to amend para. 5.2.1.1. to simplify collision warning requirements for vehicles of category M₁. Industry objects the para. 2.14. amendment as unnecessary and potentially subject to misinterpretation as a requirement change. Industry agrees with dropping the 0.8-second prior warning requirement but finds the resulting text difficult to understand and proposes alternative wording that harmonizes para. 5.2.1.1. with paras. 5.2.2.1. and 5.2.3.1., specifying that a collision warning shall be provided no later than the start of emergency braking intervention.

This document contributes to consolidated text and a risk catalogue for artificial intelligence in the automotive sector. It defines AI as a field of computer science focused on creating systems capable of performing tasks requiring human intelligence, including learning, reasoning, problem-solving, natural language processing, and decision-making. High-priority AI use cases include perception, planning, and motion-control driving functions, as well as driver assessment systems. The document identifies 14 risks organized across five lifecycle stages: AI and use case specification, model architecture and training processes, data specification and management, verification and validation, and operation and in-use monitoring. It provides detailed risk descriptions and references emergent practices for managing these risks, including ISO/PAS 8800, NIST AI RMF, and EU AIA approaches. Lower-priority use cases referenced include AI-06-09 for periodic technical inspection and AI-06-12 for cybersecurity threat detection.

Proposals for revisions to Section I including highlighted deletions, addition of two paragraphs (2.3, 2.4) in Section II with a request to add safety benefits to para. 2.6, editorial requests for text placement in Section III introducing use case content, small editorial proposals in Section IV’s introduction, merging of whole lifecycle and organizational risks, removal of para. 4.6 (systematic performance disparities) in favour of para. 4.5, revision of para. 6.2 (concept drift), removal or moving of para. 6.5 to whole lifecycle risks, and substantive suggestions in Section V for deletion, merging and restructuring of Table 2 with standard and title references only. Annex 1 critiques the need for extended descriptions.

UN IWG CLIV presented a draft UN R regulation proposal for buses at May UN GRSP session covering physical inspection system with no sensing required. Discussions on light vehicle regulation, paused since early 2026, can now resume. Light vehicles will have sensing related performance requirements. ISO CPD surrogates availability will be crucial to implement the regulation. UN IWG CLIV will hold a 4-day workshop from 08–11 September, likely at UTAC/France, focusing on light vehicles, welcoming ISO CPD expert participation and presentations on ISO CPD status and test tools.

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.

Unlock refers to transition of a doorlatch system into a state in which operation of the latch-release control is no longer inhibited, allowing the latch to disengage from the striker. Unlatching refers to transition into a state in which the latch and striker are no longer capable of withstanding separation forces, thereby allowing the door to move away from the vehicle body structure. Opening refers to the action by which a door is moved from its closed position to an open position through mechanical force or energizing an actuated device. Child Safety Lock System is a locking device which, when engaged, prevents operation of the interior door handle or other release device.

Clarifications to definitions: “Child-Safety Lock System” to clarify that it prevents unlatching when engaged, regardless of unlock state; amending “Unlock” to specify that child safety lock systems remain effective; amending “Unlatch” to define it as the transition where latch and striker no longer withstand separation forces; adding definitions for “Door Opening”, “Latch release control”, “Door handle”, and “Retractable door handle”.

Proposal to clarify the EDR trigger input in the case of vehicles approved to UN R169 (M₂, M₃, N₂, N₃) equipped with airbags (Supplemental Restraint Systems).

Comments on the proposal for a03 series of amendments to UN Regulation No. 160. Modifications include renumbering paragraph 2.2 as paragraph 2.25, deleting paragraph 2.25, and amending definitions for “End of event time,” “Engine throttle, percent full,” “Non-volatile memory,” and other terms. New paragraphs 2.71–2.82 introduce definitions for rollover protection system, advanced emergency braking system, blind spot monitoring system, and driver assistance systems. Paragraphs 5.3.1, 5.3.2, and 5.3.3 are amended to clarify triggering and locking conditions for rollover events and vulnerable road user events, and to establish time zero. Paragraph 5.4.3 clarifies crash test requirements.

CLEPA proposes standardized testing conditions for harmonics and flicker in UN R10 across countries with differing grid voltages and frequencies. Three cases are presented: Case 1 applies requirements to 220–240 V single-phase or 380–415 V three-phase at 50 or 60 Hz only; Case 2 permits multi-voltage operation but tests only at 220–240 V or 380–415 V; Case 3 applies scaled limits for region-specific operation at different voltages such as 100 V, with IEC 61000-3-3 and IEC 61000-3-11 marked not applicable due to impedance specifications limited to 220–250 V systems.

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.

This document is also available with tracked changes.

Additional validation work to support the the proposal to:
• Provide new evidence based on additional analysis.
• Compare MAW window validation and RDE results using work, fuel, and CO₂-based parameters.

Proposal to establish approval requirements for the particle emissions of replacement brake pads (based on the laboratory method established by GTR 24).

This proposal is to add Component and Separate Technical Units (STU) approvals regulatory supplement to the UN Regulation No. 159 for “Uniform provisions concerning the approval of motor vehicles with regard to the Moving Off Information System for the Detection of Pedestrians and Cyclist”
.

The Special Interest Group on Component & Separate Technical Unit (SIG-C&STU) for the Supplement of UN Regulations 151, 158, 159 and 166. Proposal adds Component and Separate Technical Units (STU) approvals requirements.

The Special Interest Group on Component & Separate Technical Units (SIG-C&STU) proposes amendments to UN R159, UN R158, UN R151, and UN R166 to add Component and Separate Technical Unit approvals. For UN R159, the proposal introduces a universal functional block structure separating Detection, Control, and Human Machine Interface functions, with Component or Separate Technical Unit fulfilling Detection and Control as minimum requirements. The regulation is restructured into three parts: vehicles without approved Component or Separate Technical Unit, vehicles with approved Component or Separate Technical Unit, and Component or Separate Technical Unit specifications. UN R158 adds new devices for Rear-View Camera Systems and Detection Systems to Part I, with corresponding installation requirements in Part II. The group requests written comments within four weeks and plans submission to Working Party 29 in June 2026.

Proposal to correct the wording in UN R43 (Safety Glazing). The expert from the European Association of Automotive Suppliers proposes amending paragraph 8.2.1.1. to modify a table listing tests for windscreens and glass panes of various types, including toughened glass, ordinary laminated glass, treated laminated glass, and glass-plastics. The amendment corrects the title of the optical distortion test listed in the table.

Proposal to amend para. 8.2.1.1. to replace “Optional distortion” with “Optical distortion” in the table of tests for windscreens and glass panes. The amendment corrects the title of the optical distortion test listed in the table.

Proposal to amend UN R159:

• Insert new title establishing a three-part regulatory structure for Moving Off Information Systems approvals,
• amend and renumber paragraphs throughout to reorganize content into Part I (vehicles regarding MOIS), Part II (vehicles regarding MOIS installation of approved Component or Separate Technical Unit), and Part III (MOIS Component or Separate Technical Unit),
• insert new paragraphs defining approval types and vehicle/component/STU classifications,
• amend definitions to clarify MOIS Component and Separate Technical Unit,
• establish permitted variations and representative test setup requirements,
• insert new Part II specifications and test procedures for installed approved-type systems,
• insert new Part III comprehensive specifications and test procedures for Component and STU covering detection, control, human-machine interface, automatic deactivation, information signals, collision warnings, and failure warnings,
• insert new Part III test procedures including static crossing tests, longitudinal stopping and moving-off cyclist tests, failure detection and automatic deactivation tests,
• insert new Annexes 2–7 providing communication and information documents for vehicle and component/STU approvals,
• renumber existing Annexes to 8 and 9,
• introduce approval mark provisions for components and STUs.

This document presents VDA 812-001 (05/2026), a recommendation for qualification of pyrotechnics and inflators for automotive restraint applications. The recommendation combines a Propellant Information Package and inflator ageing procedures. Propellant must demonstrate robustness against thermal stimulus of 107°C for 408h or 90°C for 1000h and moisture stimulus, with mechanical stability, density, and burn rate criteria assessed before and after ageing cycles. Inflator evaluation addresses structural safety, functional safety, effluents, performance characterization, and environmental simulation, including high temperature oven testing, accelerated heat ageing, and sequential environmental testing to ensure suitability for restraint systems.

Proposal to amend UN Regulation No. 129 to remove rebound head contact from the head acceleration requirement for all Child Restraint Systems. The regulation currently lacks consistency regarding whether rebound head movement is considered in testing. Variations in test bench design cause booster seats to pass in some laboratories but fail in others based solely on rebound contact. The proposal ensures consistency between different CRS types and reproducibility across laboratories with different test bench designs, and aligns with the approach in UN Regulations 94 and 137.

Proposal to clarify that the parking brake may be actuated while the vehicle is in motion via actuation of the vehicle’s service braking system by means of an auxiliary control which could be an Electronic Parking Brake (EPB) and to promote consistent interpretation of the activation conditions for an Emergency Stop Signal (ESS), including by application of the service braking system via the EPB control.

The e-Trailer Industry Group reports on discussions regarding electrically propelled and recuperating trailers. ISO 11992-2 Edition 4 is not safely implementable due to incompatibility with current UN regulations, missing PGNs, and risks of malfunction. ISO/TC 22/SC 31/WG 4 launched Edition 5, targeting publication in early 2027. Amendments to UN R13 and UN R100 are being developed in phases, with Phase 1 addressing trailer dynamo function and Phase 2 addressing e-axle trailers. Two workshops with Contracting Parties are planned to establish shared understanding and develop concrete parameter extensions for amending UN Regulations.

Proposal to insert new sub-paragraph 5.6.1.1.4.1 establishing that requirements of paragraph 5.6.1.1.4 shall not apply to ACSF Category A functions provided they are intended solely to support low-speed vehicle controllability manoeuvres in off-road environments, operate only until 5km/h with 1km/h tolerance, require deliberate driver activation, require driver presence in driver’s seat with fastened safety belt, and allow driver to retain control and override or deactivate the system at any time.

Proposal to amend para. 2.8 of Annex 8 to add subparagraph (c). The amendment addresses trailers utilizing service braking system energy reserves for automatic brake requirements. Current para. 2.8 includes options (a) and (b) requiring spring brake pressure reduction or corresponding pressure reduction in spring compression chamber. New subparagraph (c) permits alternative designs where combined service braking and parking braking system activation holds a laden trailer on 18 percent gradients at any service brake energy reservoir pressure from 850 kPa to 0 kPa, providing greater realization flexibility while maintaining required holding performance.
