He welcomed the progress done on the drafting of guidelines for ADS safety. He explained that OICA would welcome proposals from Contracting Parties for ADS regulations based on the guidelines prepared by GRVA.

26. The representative of OICA advised to initiate a review of the UN Regulations and UN GTRs with regards to their fitness for ADS, including driverless systems, as these regulations might refer to drivers.

27. The Chair of GRVA explained that AC.2 discussed the need to review the UN Regulations and UN GTRs and was in the process of setting a coordinated approach.

28. The representative of the European Commission fully recognized the need to review the Vehicle Regulations, which were linked to drivers, to accommodate for automated/autonomous driving.

29. The representative of the United States of America advised that this task could require a phased approach, one phase being the identification of UN Regulations and UN GTRs of relevance and a second phase being the evaluation of the provisions and test requirements that might be linked to drivers.

30. WP.29 requested all GRs to perform a screening of the UN Regulations and UN GTRs of relevance until March 2023 and agreed to resume consideration of a coordinated approach for reporting to AC.2 and WP.29.

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.

He explained that: 33 contracting parties notified their DETA Focal Point, about 12400 approvals were uploaded by 13 contracting parties, about 5560 manufacturers were uploaded and could be selected in DETA by the Type-Approval Authority, and that 13 manufacturers were having access to their own approvals in DETA. He explained the situation with regard to contracting new features: the Unique Identifier module, the Mass Upload Functionality and the two-factor authentication to increase the security of the system. He reported on the activities of the group to reflect on possible extension of DETA to increase the attractiveness of the system for the contracting parties of the 1997 and 1998 Agreements and on the state of play with regards to the DETA summary document on UI marking.

69. The representative of OICA clarified that, while the Unique Identifier by default applies to all UN Regulations, the GR working parties should identify those UN Regulations for which the use of the Unique Identifier was not appropriate and should not be used. He also suggested that the draft contract for the UI development be reviewed with the various sponsors and finalised as soon as possible.

70. The representative from Germany, Chair of the IWG on DETA, presented (WP.29-185-13) a proposal for amendments to the ‘specifications and application guideline for the Unique Identifier (UI) module’, document ECE/TRANS/WP.29/2019/77 and (WP.29-185-12).

72. The representatives of Japan reported on the current status of discussions in the GRVA IWG on VMAD with regards to scenarios catalogues, which was still discussing this item at a high level of abstraction.

73. The representative of the United States of America explained that the IWG on FRAV was still discussing, among others, whether scenarios were needed for the development of ADS or for their performance assessment.

74. The representative of OICA recalled that the DETA database was designed originally for the purpose of type approval data exchange; therefore, it was not appropriate for all types of extensions which in fact would entail a totally new, separate database software.

75. The representative of the Netherlands agreed with the technical comment of the representative of OICA regarding the current function of DETA. He explained that WP.29 would need to reflect on modern ways to exchange information.

76. The Chair of GRVA suggested that the GRVA IWGs could advice whether these functions could be needed. He invited WP.29 to consider whether countries would want a centralized approach to exchange information or a decentralized way that all countries would need to implement.

77. The representative of Switzerland stated that it was premature to consider details. He advised to keep the discussion at a strategic level and focus on principles. He supported this discussion and advised that WP.29 embarked in a modern, flexible and dynamic way to address the technological progress brought by ADS.

78. WP.29 invited the IWG on DETA to further explore options and thanked Germany for continuing hosting DETA.

14. The expert from Germany wondered if it would be acceptable to drive, for a limited time, with one headlamp (passing beam) of the matched pair, as defined in paragraph 4.18. of ECE/TRANS/WP.29/GRE/2021/14. He recalled that, under the current requirements for periodical technical inspections in the European Union (e.g. paragraph. 4.1.1 (a) of directive 2014/45/EU), a non-working headlamp was a minor defect which would not impede passing the inspection. He added that footnote (a) to paragraph 5.2.2. in ECE/TRANS/WP.29/GRE/2021/14 might lead to an expectation that, in the worst-case scenario with one remaining headlamp of the matched pair, only 50 per cent of luminous intensity would be reached in some elements instead of 100 per cent for one headlamp.
