27. GRVA received a progress report from the expert from United Kingdom of Great Britain and Northern Ireland, Co-Chair of the Special Interest Group on UN Regulation No. 157 (GRVA-12-36) on the activities of the group. He introduced ECE/TRANS/WP.29/GRVA/2022/3 and ECE/TRANS/WP.29/GRVA/2022/4, aimed at proposing provisions addressing lane change manoeuvres and increasing the maximum design speed of ALKS, up to 130 km/h.

28. The expert from Germany introduced GRVA-12-20. She announced that some discussions were still taking place and that a revised document would be produced in the course of the week. The expert from EC recalled that the document had been discussed by the IWG on EDR/DSSAD and considered by GRSG, as it had been initially drafted as an amendment to UN Regulation No. 160 (EDR). He explained that following discussions, it was advised that the provisions should be inserted in UN Regulation No. 157, and that therefore the document had then been submitted to the Special Interest Group on UN Regulation No. 157. The expert from CLEPA confirmed that the industry did not have issues with the proposal but that a few last-minute clarifying amendments to the document were necessary. The expert from AAPC mentioned that he would circulate the proposal among his members, with the aim to provide feedback, if possible, during the week.

29. Later in the week, GRVA considered a revised document (GRVA-12-20/Rev.1). The expert from the United States of America, Co-Chair of the IWG on EDR/DSSAD, requested the possibility for her group to review the revised proposal, at a meeting taking place one working day after GRVA. Accordingly, GRVA agreed to keep the text contained in the document in square brackets.

30. GRVA reviewed GRVA-12-51 and GRVA-12-51/Rev.1 (note: document not available) prepared during the week and requested the secretariat to submit GRVA-12-52 (based on formal documents ECE/TRANS/WP.29/GRVA/2022/3, ECE/TRANS/WP.29/GRVA/2022/4 and informal documents GRVA-12-34, GRVA-12-35, GRVA-12-20/Rev.1 (including square brackets) to WP.29 and AC.1 for consideration and vote at their June 2022 sessions, subject to final review by GRVA at its May 2022 session.

23. The expert from EC proposed to strengthen tyre rolling resistance and wet grip performance requirements (GRBP-75-29 and GRBP-75-30). GRBP invited him to submit an official document for consideration at the next session. The experts from Germany and the Netherlands stressed the importance of rolling noise and the need to include it in the scope of the future modifications as well.

TF TA will address the tyres abrasion performance by determining a standardized measurement method which will allow for the quantification of the microplastic emissions in the environment. At the same time, the TF TA will investigate the correlation between abrasion rate and durability and consider the inclusion of both abrasion rate and durability

35. In cooperation with the Working Party on Pollution and Energy (GRPE), GRBP established a Task Force on Tyres’ Abrasion (TF TA) under the Co-Chairmanship of France and the European Commission, adopted its Terms of Reference (Annex IV, based on GRBP-75-39-Rev.1) and encouraged all experts to participate in the activities of TF TA. Many experts volunteered to contribute to the work of TF TA.

27. The expert from EC introduced, through a presentation (GRSG-123-30), the draft new UN Regulation No. XXX of VRU-Proxi on Direct Vision (ECE/TRANS/WP.29/GRSG/2022/7 and GRSG-123-09 amending it). He underlined that the new draft UN Regulation would enhance the direct visibility of vulnerable road users from the driver seat, by reducing to the greatest possible extent the blind spots in front of and to the side of the driver. As a follow-up to the EC presentation, the expert from Germany remarked that driver’s behaviour and skills to judge critical situations without technical assistance is increasingly important since more than 90 per cent of road accidents are estimated to result from some level of human error. Therefore, he introduced GRSG-123-08, to ensure among others, that automated vehicles are equipped with the technology to support the driver especially during low-speed manoeuvres. The expert from AAPC endorsed, in principle, the proposal but suggested replacing the term “automated vehicle” with “VRU collision system”. The expert from the United States of America supported the proposal but suggested sending it to IWG on Functional Requirements for Automated Vehicles (FRAV) to verify the consistency with already defined terminology. The expert from the United Kingdom expressed concern for the late submission of the document introducing substantive changes to the draft UN Regulation and seemingly introducing alternative technology. He therefor suggested discussion of GRSG-123-08 at another stage. The expert from Germany suggested discussing the document with the Automated/Autonomous and Connected Vehicles Working Group (GRVA) to determine consistent definitions. The expert from EC replied that the approach proposed by GRSG-123-08 was not new and not endorsed by the majority of contracting parties because the IWG mandate was for a unique technology for direct vision. The experts from Denmark, France, the Netherlands and the United Kingdom supported the position of EC to adopt the draft UN Regulation and discuss GRSG-123-08 at the October 2022 session of GRSG. The expert from the Russian Federation assumed that the new UN Regulation would apply to large trucks and buses (M3 and N3 categories of vehicles) according to the design configuration of the vehicle. The expert from EC confirmed it and clarified that there were options and protocols for manufacturers to follow also for small buses and trucks (N1, N2, M1 and M2). The expert from OICA acknowledged the merit of the proposal. However, he pointed out the issue of lack of harmonization of the three-dimensional point machine to correctly implement the proposed UN Regulation. The expert from Sweden supported the draft new UN Regulation. However, in his view, application on long vehicles would be challenging particularly in view of the changes proposed in GRSG-123-08.

28. GRSG adopted ECE/TRANS/WP.29/GRSG/2022/7 as amended by annex VII to the session report. The secretariat was requested to submit the proposal as draft new UN Regulation No. XXX (VRU Direct Vision) to WP.29 and AC.1 for consideration and vote at their November 2022 sessions.

29. GRSG agreed to send GRSG-123-08 to IWG VRU-Proxi for further elaboration and resume discussion at its October 2022 session for possible amendments to the official proposal to WP.29 of new UN Regulation No. XXX (VRU Direct Vision).

30. GRSG agreed to send GRSG-123-25 and GRSG-123-26, tabled by the expert from Spain, to IWG VRU-Proxi for further elaboration.

27. The expert from EC introduced, through a presentation (GRSG-123-30), the draft new UN Regulation No. XXX of VRU-Proxi on Direct Vision (ECE/TRANS/WP.29/GRSG/2022/7 and GRSG-123-09 amending it).

78. The expert from OICA introduced GRVA-13-33 concerning the interpretation of the wording “new engine start/run cycle”. GRVA supported the interpretation 1 referred to in that document and requested that proper attention is given to the French translation of the corresponding text in the Regulation.

79. GRVA thanked the IWG for their work and contributions to finalise the work to update the requirements on AEBS for heavy duty vehicles.

31. The representative of the European Commission introduced informal document WP.29-187-25, a proposal prepared by the European Commission regarding a IPR policy. He stressed that this document was not agreed on by AC.2 and invited the representatives of the WP.29 member States to share their feedback with him. The representatives from Canada and the United States of America stated that more time would be needed to examine this document and the potentially new process.

32. WP.29 invited all the representatives to examine the informal document and send their feedback to the representatives of the European Commission to enable progress in the next meeting of AC.2 and WP.29 on this proposal.

GRPE asked all interested parties to provide written comments to the secretariat, with the intention still being to prepare a working document for the January 2023 session of GRPE.

GAR note: At the time of this writing, document GRPE-86-44 had not been published by the GRPE secretariat. You may wish to consult the list of informal documents for this GRPE session in case the document has since been made available.

30. The representative from the European Commission, Chair of the IWG on RDE, introduced GRPE-86-29 providing an update about the latest intention with the finalization of the new UN Regulation on RDE. She informed that more changes beyond the remaining square brackets would be needed and that a final text was expected to be available in the first weeks of July 2022. She kindly requested GRPE to accept a post session submission, and the consideration of the informal document through a written procedure over the summer.

31. GRPE agreed to consider a draft proposal for a draft new UN Regulation on RDE as post session informal document GRPE-86-45 to be shared by the secretariat with all GRPE participants mid July 2022. GRPE asked all interested parties to provide written comments to the secretariat before 19 September 2022, to prepare a working document for the January 2023 session of GRPE.

63. The Chair asked GRPE for their comments on the draft Framework Document on Vehicle Whole-Life Compliance (ECE/TRANS/WP.29/2021/148), as agreed during the last session of GRPE (ECE/TRANS/WP.29/GRPE/85, para. 71).

The representative from OICA introduced GRPE-87-08 and GRPE-87-09. The representative from Japan supported ECE/TRANS/WP.29/GRPE/2023/3 and GRPE-87-08. The representative from the European Commission had some objections to some elements included in GRPE-87-08 and sought further clarification to make sure over-regulation is not included in the proposal, as might be the case where requiring not to perform RDE trips in reverse gear.

40. The representative from OICA highlighted absolute legal clarity was needed, as stakeholders in other fora had made statement about attempts to make vehicles fail RDE tests, legally compliant but driven in unrealistic conditions.

41. The representative from the European Commission did not support GRPE-87-09, requesting to try and avoid repeat the sub-optimal situation that led to last resort decision in other GRPE legislation and confirmed the European Commission had no mandate to agree on the inclusion of 2 levels in UN Regulation on Global RDE. The representative from Italy understood the intention of the OICA’s proposal, and was open to OICA’s proposal in the spirit of harmonization that is operational.

42. The representative from the UK introduced GRPE-87-44 and GRPE-87-45 and supported an adoption of UN regulation on Global RDE during this session of GRPE.

43. Following additional activities from all concerned parties during the session, the representative from the European Commission introduced GRPE-87-49 as a revised proposal for a new UN Regulation on Global RDE which represented a consensus on the various proposals presented previously.

44. The representatives from France, Germany, Italy, Japan, the UK and the European Commission supported the proposal. GRPE agreed with the content of GRPE-87-49.

45. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/3 as amended by GRPE-87-49, as reflected in Addendum 2, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2023 sessions as draft new UN Regulation No. [XXX] on Global RDE.

Proposal to correct drafting errors within the 06 and 07 series of amendments.

48. The representative from the European Commission introduced ECE/TRANS/WP.29/GRPE/2023/5. He added that this proposal only applied to the 06 series of amendments to UN Regulation No. 49. GRPE supported the content of the proposal.

49. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/5 and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2023 sessions as draft new supplement to the 06 Series of Amendments to UN Regulation No. 49.

Proposal to permit the use of hydrogen (H2) as fuel for emissions type approval of heavy-duty vehicles.

50. The representative from OICA introduced GRPE-87-50, summarizing the proposals on the inclusion of hydrogen as a fuel for internal combustion engines in heavy duty vehicles. He introduced ECE/TRANS/WP.29/GRPE/2023/6 as amended by GRPE-87-30. The representative from the European Commission introduced GRPE-87-31 to support the previous proposal.

51. The representatives from France, Germany, Italy, the Netherlands and Sweden supported the proposal and congratulated all parties involved in the development of this proposal. The representative from the EC highlighted that hydrogen internal combustion engines were important to achieve heavy duty vehicles CO2 emission reduction targets. He also added that the scope of engines covered would be enlarged, as well as the inclusion of dual fuel engines in forthcoming amendments to the related legislation.

52. The representative from India also supported the proposal and requested additional information on the fuel specifications for hydrogen, informing that some parameters differ in UN GTR No. 15 compared to UN regulation No. 49. The representative from OICA confirmed fuel specifications are aligned between UN Regulations Nos. 154 and 49 but could not confirm they are the same in UN GTR No. 15. He explained that the difference might come from the different specifications for hydrogen whether they are used in fuel cells or internal combustion engines. The hydrogen purity needs to be better for fuel cells, explaining potential tighter tolerances if only one grade of hydrogen fuel is specified. He concluded by saying that a similar issue might arise in heavy duty applications when fuel cell trucks are being deployed more broadly.

53. The representative from France introduced GRPE-87-53. The representative from the European Commission clarified some of the content of this proposal.

54.

55. The representative from OICA informed GRPE that OICA was exploring the possibility to also include hydrogen as a fuel in older series of amendments to UN Regulation No. 49. He noted that adding hydrogen was expected to be straight forward in the 06 series of amendments, and that an assessment was on-going for such inclusion in the 04 and 05 series of amendments.

74. The Co-Chair of the IWG on EVE introduced ECE/TRANS/WP.29/GRPE/2023/8. The representative from OICA highlighted the need to deep dive into the testing procedure and praised the progress made so far. The Co-Chair of the IWG on EVE congratulated the productive work from the IWG on this matter, especially the constructive collaboration between the members from OICA and the representatives from the European Commission from JRC to deliver on the procedure in a timely matter.

75. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/8 and requested the secretariat to submit them to WP.29 and AC.3 for consideration and vote at their June 2023 sessions as request for authorization to develop a new UN GTR on in-vehicle battery durability for electrified heavy-duty vehicles.

Proposal to clarify conditions for use of the DETA Unique Identifier marking.

8. The expert of IWG SLR presented draft amendments to UN Regulations Nos. 148, 149 and 150 that introduce summary documents to be placed in the electronic Database for the Exchange of Type Approval documentation (DETA) to support the use of the Unique Identifier (UI) (ECE/TRANS/WP.29/GRE/2022/10, ECE/TRANS/WP.29/GRE/2022/11 and ECE/TRANS/WP.29/GRE/2022/12). GRE pointed out that a template summary document should be developed by IWG DETA and endorsed by WP.29. Awaiting WP.29 and/or IWG DETA guidance on the matter, GRE decided to continue consideration at the next session.

9. GRE noted that the use of UI for a particular UN Regulation should only be possible when the following two conditions are met:

• the corresponding summary document has been defined in the Regulation; and
• DETA is providing access to the Summary Document.

10. To stress these requirements, the expert from EC proposed an amendment (GRE-87-24-Rev.1). GRE adopted the proposal and requested the secretariat to submit it for consideration and vote at the March 2023 sessions of WP.29 and AC.1 as a draft Supplement to the 00 and 01 series of amendments to UN Regulations Nos. 148, 149 and 150.

11. In the context of possible replacement of traditional approval markings by UI, the expert from CITA presented a proposal with the aim to ensure the availability of sufficient information on the device for periodic and roadside inspections (ECE/TRANS/WP.29/GRE/2022/13 and GRE-87-07). GRE agreed to revert to this proposal at the next session.

32. The expert from the Informal Working Group on Electromagnetic Compatibility (IWG EMC) presented their status report and outstanding issues (GRE-87-21). The expert from EC reported on the results of their market surveillance tests of vehicles in different normal conditions of use (GRE-87-12-Rev.1) which had demonstrated that certain vehicles with new technologies (e.g. multiple propulsion engines) may have the electromagnetic emissions occasionally higher than the regulatory threshold. On that basis, the expert from EC requested an extension of IWG EMC mandate (GRE-87-25). GRE agreed that IWG EMC should take over the topic of ‘normal conditions of use’, as proposed by the expert from EC. Depending on the IWG EMC progress in the coming months, GRE decided to address, at its next session, possible amendments to the Terms of Reference of IWG EMC.

11. The expert from the European Commission, on behalf of the IWG on awareness of Vulnerable Road Users Proximity in low-speed manoeuvres (VRU-Proxi), informed GRSG of the work progress (GRSG-124-37). He added that the group had convened twice (in May and July 2022) to discuss improvement of UN Regulation No. 158 on the temporary obstruction of the monitor view. Phase 2 of the draft UN Regulation on Direct Vision was also discussed and IWG noted that vehicles powered by electric battery or hydrogen data were not yet available for an assessment of the level of adaptation that would be needed. Information and data on direct vision for high-capacity transport would be provided at the next session of IWG to support adaptation. He said that a contracting party had prepared a draft new UN Regulation for a highly automated system to take over control from the driver if a VRU danger was detected.

The existing transitional provisions do not address tyres produced in accordance with the applicable requirements and placed in distribution channels before 7 July 2026. Therefore, a new transitional provision is proposed based on the clause R.4 of part C – “Transitional provisions for replacement parts for vehicles in use” of the General Guidelines for United Nations Regulatory Procedures and Transitional Provisions in UN Regulations. It will clarify that new tyres manufactured before 7 July 2026 and approved according to the 02 or 03 series of amendment will be allowed to be sold and fitted on vehicles in use for additional period not exceeding 30 months from 7 July 2026.

Proposal to transpose the amendment 1 to UN GTR13, Phase 2 (GTR13-PH2). This proposal contains numbers of improvements to the original GTR to promote technical harmonisation and to achieve enhanced reproducibility and reproducibility of the test requirements, higher clarity and consistency, adaptation to technical progress,

33. The secretary of the Task Force to transpose Amendment 1 of UN GTR No. 13 into UN Regulation No. 134, introduced GRSP-72-17. GRSP noted that material compatibility, the remote Thermal Pressure Relief Device (TPRD), conformity of production and other elements proposed by GRSP-72-17 were still under discussion in the Task Force.

34. GRSP agreed to resume consideration on the transposition of UN GTR No. 13, Phase 2 into UN Regulation No. 134 on a reviewed proposal drafted by the Task Force at its May 2023 session. The proposal was expected to be submitted as an official document by 20 February 2023.
