Proposal to permit the use of virtual testing as an alternative methodology to the physical tests. This approach requires the preliminary assessment of the methodology to be used.

Proposal based on ECE/TRANS/WP.29/GRPE/2021/14, as amended by Annex X of the report of the 83rd GRPE (Supplement 7 to the 06 series of amendments). Some modifications were not taken onboard in the 07 series of amendments (and Supplements 1, 2 and 3). For the remaining amendments included in this proposal, the justifications are:

1. UN R49 does not define linearity requirements for humidity sensors. As the humidity content of the intake air is an essential measure for the calculation of the specific exhaust emission, it is important to add requirement for humidity sensor. Reference: ISO 16183 the accuracy of the absolute humidity shall be +- 5%.
2. Typo error: the instrument should be now in NOx mode.
3. To clarify the operation procedure, make the text easier to be understood.

Proposal to add assembly plant(s) to the approval information document.

Proposal to allow higher tolerance for pressure measurement under paragraphs 4.7 and 4.8 (+ aligned intake and exhaust) in order to avoid refusal of test due to the non-compliance of pressure accuracy and based on the low impact on the αd. Value or approach (linearity?) to be discussed.

Proposal to correct inconsistencies in the time between the measurement of the end temperature and the end of the Type 1 test at 23°C for the ATCT family criterion check and in the f_jDyno force calculation.

Proposal pursuant to revisions made during the 26th VRU-Proxi informal group session.

Proposal makes a few minor adaptations and clarifications to the existing requirements.

25. The experts from France introduced ECE/TRANS/WP.29/GRSP/2022/18
and ECE/TRANS/WP.29/GRSP/2022/19, on behalf of the ad hoc group to develop an amendment that clarifies the definitions of the cowl monitoring and windscreen areas, as well as of the jerk area. The expert from the Netherlands recommended that a specific symbol in the type-approval marking should be added for vehicles approved using the specific provisions related to bonnet rear reference line. Accordingly, the experts from France and OICA introduced GRSP-72-41 and GRSP-72-44 amending respectively ECE/TRANS/WP.29/GRSP/2022/18 and ECE/TRANS/WP.29/GRSP/2022/19.

26. GRSP adopted ECE/TRANS/WP.29/GRSP/2022/18 and ECE/TRANS/WP.29/GRSP/2022/19, both as amended by annex IV of the session report. The secretariat was requested to submit the proposals as Supplement 2 to the 03 Series of Amendments (ECE/TRANS/WP.29/GRSP/2022/18) and as Supplement 1 to the 04 Series of Amendments (ECE/TRANS/WP.29/GRSP/2022/19) to UN Regulation No. 127 (Pedestrian safety) to the June 2023 sessions of WP.29 and AC.1.

Proposal to add category O to the scope

24. GRSP resumed discussion on a proposal of amendment to UN Regulation No. 100, tabled by the expert from CLCCR that would introduce provisions for a type of electric axle in a trailer (ECE/TRANS/WP.29/GRSP/2022/14 and GRSP-72-18 amending it). The expert from France presented GRSP-72-27, introducing some comments and amendments to the proposal. GRSP agreed to resume discussion on a revised proposal introducing provisions for a type of electric axle tabled by the expert from CLCCR in cooperation with the expert from France at its May 2023 session.

Proposal to clarify the requirements for safety-belt reminder systems on test procedure (first and second level warning), visual warning and requirements for Seat belt Reminder of rear seat row(s).

16. GRSP resumed discussion on a proposal (ECE/TRANS/WP.29/GRSP/2022/13) tabled by the expert from France on clarifying the assessment of the connection of the Safety-Belt Reminder (SBR) system in the case of removable seats. GRSP also noted a presentation (GRSP-72-23) to introduce a proposal for a new series of amendments (GRSP-72-22). The expert from France explained that the proposal would clarify the requirements for SBR systems on test procedure (first- and second-level warning), visual warning and requirements for SBR in the rear seat row(s).

17. GRSP agreed to resume discussion at its May 2023 session on a revised document combining GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13, as a new series of amendments. GRSP requested its experts to provide feedback on GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13 to the expert from France before the deadline for submission of official documents for the May 2023 session.

Proposal to ensure that the test procedures for retreaded tyres are aligned with the text adopted by WP.29 per document WP.29/2021/8 for UN R117.

Proposal to introduce an explanation clarifying the possibility for Approval Authorities to recognise Certificates of Compliance for Cyber Security Management Systems (CSMS) issued by the Approval Authority of another Contracting Party.

Proposal to require a vehicle stability function on vehicles with four axles commercial vehicles over 25 tons in light of their specific use.

Proposal to correct misalignment between GRSG/2022/10 as amended and adopted by the 123rd GRSG session and subsequently submitted for adoption by WP.29 during its November 2O22 session with document GRSG-123-15/Rev.1 as discussed and agreed during the 123rd GRSG session.

12. GRSG resumed consideration of the new UN Regulation No. [165] on reverse warning, with reference to UN Regulation No. 158 as the requirements for the pause switch. However, a proposal was yet to be provided by GRSG on this subject. GRSG also recalled that it was agreed to submit a proposal (GRSG-123-31) to IWG VRU-Proxi, for a possible amendment of paragraph 16.1.3.1. which would amend draft Supplement 2 to the original version of UN Regulation No. 158, that had been submitted for consideration and vote at the November 2022 sessions of AC.1 and WP.29 (ECE/TRANS/WP.29/2022/123). The expert from Japan informed GRSG that proposal had not yet been provided by IWG VRU-Proxi. Therefore, GRSG considered GRSG-124-29, tabled by the experts from France and Japan, proposing to remove the amendment of paragraph 16.1.3.1. since the opportunity for temporary obstruction without any countermeasure preserving safety was not acceptable. While awaiting a further proposal from the IWG, GRSG adopted GRSG-124-29. The secretariat was requested to submit ECE/TRANS/WP.29/2022/123 as amended by GRSG-124-29 (ECE/TRANS/WP.29/2022/123/Rev.1), deleting the proposed amendment to paragraph 16.1.3.1., for consideration and vote at the November 2022 sessions of WP.29 and AC.1. In the meantime, GRSG expected to consider at its March 2023 session, a new proposal of amendments to paragraph 16.1.3.1., revised by IWG VRU-Proxi.

55. GRVA discussed GRVA-14-54, prepared by the Secretary on the basis of input received, and proposing guidance to the GRs dealing with the screening of UN Regulations and UN GTRs. The proposal received comments from the experts from China, France (GRVA-14-53), Germany, Japan, the Netherlands and the Russian Federation as well as from OICA (GRVA-14-56). GRVA confirmed that ALKS was not in the scope of this screening. GRVA endorsed GRVA-14-54/Rev.1 with guidance for the experts from all GRs, involved in these activities. GRVA requested the Chair to inform AC.2 about this coordination between the GRs.

113. The expert from France presented GRVA-14-22, updating GRVA on national regulatory activities for the deployment of vehicles equipped with ADS in France. The expert from OICA welcomed this presentation and encouraged other countries to do the same, as such information was of crucial importance in order to develop ADS.

54. The expert from France introduced GRVA-14-36, informing GRVA on the work done by the Task Force (TF) on the fitness of GRVA UN Regulations and UN GTRs for ADS.
