Proposal to expand alignment of UN R152 with UN R131-02 series, in particular to clarify that the Technical Service may test in any conditions within those specified by the performance requirement section of the regulation, with any other speeds within the prescribed speed range. In addition, the Technical Service may verify that the control strategy is not unreasonably changed or AEBS switched off in other conditions than those specified in the performance requirement section and the report of this verification shall be appended to the test report.

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.

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.

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.
