Proposal based on GRSG/2026/38 to amend para. 2.18. to define end of event time separately for planar events and all other events, amend para. 2.20. to redefine engine throttle percent full, insert new definitions for Advanced emergency braking system (AEBS) and Trigger activated, amend para. 5.4.3. to modify crash test data requirements and reference UN Regulations Nos. 95 and either 94 or 137, and amend Table 1 in Annex 4 to modify data element requirements including changing Air bag warning lamp and other elements from conditional to Mandatory, adding AEBS event recording, modifying Yaw Rate recording intervals and sample rate, clarifying Vulnerable road user secondary safety system warning indicator status recording, modifying Accident emergency call system status recording interval, and revising footnotes regarding TTC calculation and AEBS requirements, effective upon entry into force of the 03 Series of Amendments.

European Commission priorities for EDR Step 3 include improving detection of vehicle-to-vulnerable road user collisions and low-severity vehicle-to-vehicle collisions through adjusting delta-v trigger thresholds, developing new jerk-based trigger criteria, and exploring ADS collision detection for EDR triggering in automated vehicles on a long-term timeline. Data elements and format must be ensured to remain up-to-date with new safety system developments and close gaps between light and heavy vehicles through reviewing data elements in light of newly regulated safety systems and mirroring DDAW, ADDW and DCAS data elements from UN R160 to UN R169 on short-term and ongoing timelines.

The Informal Working Group on Advanced Emergency Braking System held its 2nd meeting on 18 June 2026. Australia had submitted documents GRVA/2026/21 and GRVA-25-36 proposing amendments to UN R152. For para. 2.14, the group agreed to insert a footnote stating “this value is understood to be a minimum value,” with a working document to be prepared for next GRVA. For para. 5.2.1.1, Australia withdrew its proposal to remove the 0.8s TTC warning condition after safety concerns were raised. CLEPA-OICA, UK and Australia will prepare a clarification proposal for next GRVA.

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 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 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.

Proposal to add Observer Rating of Drowsiness (ORD) as a primary drowsiness assessment method alongside the Karolinska Sleepiness Scale (KSS) for the Driver Drowsiness Alarm Warning (DDAW) system. The proposal modifies warning thresholds to reference ORD level [D4], updates validation testing requirements in Annex 4 to include ORD assessment procedures with specified assessor training and concordance rate standards, and establishes measurement intervals of 5 minutes or less. Japan is conducting a driving simulator study to validate appropriate ORD warning thresholds for submission after the October 2026 session.

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.

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 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 agenda includes adoption of the provisional agenda and minutes from the thirty-eighth session; proposals for amendments to R155 concerning multistage vehicles, separate technical units and component approval, and remote operation for automated driving systems; review of cyber and software requirements in the ADS Regulation; application of RXSWIN to R156; administrative provisions in R155 and R156 regarding Type Approval Authority for CSMS/SUMS and issuing approvals for out-of-scope vehicle types; and preparation of GRVA 26.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.
