GRVA | Session 12 | 24-28 Jan 2022

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.

GRVA | Session 13 | 23-27 May 2022

28. The expert from the United Kingdom of Great Britain and Northern Ireland reported on the outcome of the Special Interest Group on UN Regulation No. 157 (GRVA-13-44). He explained that the group addressed open issues in ECE/TRANS/WP.29/2022/59: the scope and requirements for lane change capability for systems operating above 60km/h, the provisions for intentional lane crossing and evasive lane crossing, the additional DSSAD elements to be recorded related to lane changes, transitional provisions, the final review of the annex including the testing provisions and further clarification of text, as reflected in GRVA-13-43. He also highlighted potential future activities of the group, such as developing an interpretation document for UN Regulation No. 157 on the model of those developed for UN Regulations Nos. 155 and 156.

29. The expert from the United States of America, Co-Chair of the IWG on EDR/DSSAD, mentioned that the group reviewed the DSSAD provisions in the document and proposed amendments.

30. The expert from OICA welcomed the updates developed by the group. He mentioned that his delegation had still a few minor points, that would need to be addressed.

31. The expert from the United States of America advised to address the last remaining points during the week.

32. GRVA further exchanged on clarifications to the proposed text for a new series of amendments to UN Regulation No. 157 and reviewed GRVA-13-43, GRVA-13-43/Rev.1 and GRVA-13-43/Rev.2 during the week. The secretariat produced a consolidated version (GRVA-13-48 and GRVA-13-48/Rev.1) which was amended by the group on the last day.

33. GRVA adopted GRVA-13-49 and requested the secretariat to submit it, as ECE/TRANS/WP.29/2022/59/Rev.1, to WP.29 and AC.1 for consideration and vote at their June 2022 sessions.

GRVA | Session 14 | 26-30 Sep 2022

29. The expert from Japan, Co-Chair of the IWG on Event Data Recorder (EDR) / Data Storage Systems for Automated Driving (DSSAD), presented GRVA-14-39, recalling the mandate of the group, providing an overview of the group’s activities and listing the activities of the group since the May 2022 session of GRVA. He explained that the group clarified the primary objective of DSSAD, which was to record data to evaluate and monitor the overall safety performance and identify when ADS was in control of vehicles. GRVA agreed with the group’s suggestion that, while data obtained from DSSAD could be used for other purposes including liability, this was not the primary goal or objective of the DSSAD requirements.

30. He reported that the Co-Chairs of the IWG on EDR/DSSAD held discussions with the Co-Chairs of the Special Group on Automated Lane Keeping System (ALKS) and OICA to review ECE/TRANS/WP.29/2022/59/Rev.1 and replace ‘Abortion of Lane Change Procedure’, that is to be recorded, by ’Abortion of Lane Change Manoeuvre’, as proposed in ECE/TRANS/WP.29/GRVA/2022/16 under agenda item 4(d).

31. GRVA reviewed GRVA-14-40 (Inventory of best ADS storage practices (Review of the existing national / regional activities and a proposed way forward for DSSAD)) and adopted GRVA-14-40/Rev.1, a version including updates by the expert from France. GRVA requested the secretariat to submit it to WP.29 for information at its November 2022 session.
