24. The Chair regretted that GRVA did not have enough time for reviewing the proposal submitted by the expert from AVERE and also for the proposal submitted by the expert from the United Kingdom of Great Britain and Northern Ireland. GRVA agreed to consider these two items at its September 2020 session.
34. The expert from AVERA presented GRVA-04-53, introducing ECE/TRANS/WP.29/GRVA/2019/26, ECE/TRANS/WP.29/GRVA/2019/27 and ECE/TRANS/WP.29/GRVA/2019/28. The presentation contained videos, simulations and fleet data supporting the proposals for amendments to UN Regulation No. 79. The presenters referred to a driving demonstration organized by Tesla in conjunction with GRVA to justify their statements. The proposal received some comments. The contracting parties were not opposed to an evolution of the regulatory provisions based on experience, if the assurance of safety is provided. The expert from AVERE presented revised proposals GRVA-04-41 and GRVA-04-42 aimed at addressing comments received. GRVA noted that some parts of the proposals were also addressed by the proposal submitted by the expert from OICA and agreed to review it.
35. GRVA welcomed the proposal from the expert from the United Kingdom, who volunteered to lead activities on the review of the three AVERE proposals as well as the amendment proposal tabled by OICA in GRVA-04-08 with the aim to prepare a formal proposal until November 2019 in order to meet the deadline for submission of documents for the February 2020 session of GRVA.
39. The expert from OICA introduced ECE/TRANS/WP.29/GRVA/2020/22, amended by GRVA-07-20 with proposed amendments to the provisions on ACSF of Category C. He explained that GRVA-07-20 also incorporated GRVA-07-15, GRVA-07-16 and GRVA-07-19. He withdrew GRVA-07-18. The expert from AVERE supported the OICA proposal. GRVA-07-29 superseded by GRVA-07-32. GRVA had remained divided on such amendments since its fourth session.
44. The expert from AVERE introduced GRVA-07-15. GRVA requested the secretariat to distribute this document with an official symbol at its next session. He also introduced GRVA-07-16 amendment proposals to ACSF of Category C. The experts from the Netherlands and Denmark expressed reservations with the document. GRVA could not reach consensus.
43. The expert from AVERE introduced ECE/TRANS/WP.29/GRVA/2020/7 and ECE/TRANS/WP.29/GRVA/2020/8 (and their respective amendments in GRVA-05-08 and GRVA-05-24), proposing amendments to the ACSF provisions, resuming the discussion started in September 2019. He mentioned the support provided by the expert from the United Kingdom. The experts from Sweden and France provided comments. The experts from Denmark, Finland, the Netherlands and Norway expressed concerns. The expert from the Netherlands explained that the dynamics problems reported by the manufacturer, member of AVERE, were not due to the provisions in the Regulation but were due to design choices made by this manufacturer. The experts from the European Commission, Korea and United Kingdom and Northern Ireland supported the proposals; the expert from OICA, too. The expert from the Russian Federation proposed alternative proposals (GRVA-05-59) improving the text. The expert from the United Kingdom proposed GRVA-05-57 aimed at addressing the comments expressed by the expert from Sweden. GRVA reviewed all revised proposals produced by the expert from AVERE during the week but remained divided. GRVA agreed to review a revised proposal at the sixth session of GRVA, if time allows.
44. The Chair of GRVA noted the division of GRVA on this matter. He proposed that GRVA performs a general review of the Regulation at its September 2020 session.
47. The expert from AVERE introduced ECE/TRANS/WP.29/GRVA/2021/7, a revised amendment proposal to the Automatically Commanded Steering Function (ACSF) of Category B1 provisions in UN Regulation No. 79 (maximum lateral acceleration aymax). The expert from the Netherlands opposed to the proposal, as it could generate mode confusion and overreliance on the market. The experts from France, the European Commission and UK supported the proposal. The expert from Germany suggested that the proposal is further discussed by a task force. GRVA agreed to keep the proposal on hold.
50. The expert from AVERE introduced ECE/TRANS/WP.29/GRVA/2021/10 proposing revised amendments to the ACSF of Category C provisions (time range during which the lane change manoeuvre is initiated) in UN Regulation No. 79. The experts from UK, European Commissions and Japan supported the proposal. The expert from Korea supported the proposal and indicated that a longer time than the one proposed would be preferable. The expert from the Netherlands opposed to the proposal for the same reasons as the one expressed in September 2020. The expert from Norway also opposed to the proposal. He wondered about the possible benefits of stretching the limits. The expert from France supported the proposal but pointed out inconsistencies in the drawing compared to the provisions in the text. The expert from OICA supported the proposal. The expert from AVERE provided answers to the statements and questions raised. The Chair asked if all doubts were cleared. The experts from the Netherlands, Sweden, Germany and Finland still had reservations to the proposal but agreed that it could be further discussed at a task force meeting.
70. GRVA agreed, following the recommendation of the TF on ADAS, to keep ECE/TRANS/WP.29/GRVA/2021/9 and ECE/TRANS/WP.29/GRVA/2021/10 on its agenda for the January 2023 session.
71. The expert from OICA introduced GRVA-14-25, detailing an amendment proposal to the provisions on the activation of Automatically Commanded Steering Function of Category C to reduce the driver’s confusion.
72. The expert from Japan supported the proposal. The expert from the United Kingdom of Great Britain and Northern Ireland supported the intention of the proposal and suggested to review the text proposed.
73. The expert from Germany was not in favour of GRVA-14-25. He suggested to address this concern via a better human-machine interface requirement.
74. The expert from OICA presented GRVA-14-24/Rev.1, aimed at addressing the comment from the expert from Germany. The expert from Germany welcomed the modifications proposed but still had concerns with the wording of paragraph 5.6.4.5. because it would introduce a weak requirement, difficult to verify. GRVA agreed in principle with the aim of the proposal but required an improved wording for consideration at its January 2023 session.
72. GRVA noted that the review of ECE/TRANS/WP.29/GRVA/2021/9, ECE/TRANS/WP.29/GRVA/2021/10 and ECE/TRANS/WP.29/GRVA/2021/11 by the Task Force on ADAS was still ongoing. The expert from AVERE withdrew ECE/TRANS/WP.29/2021/7.
72. GRVA agreed to keep ECE/TRANS/WP.29/GRVA/2021/9 and ECE/TRANS/WP.29/GRVA/2021/10 on the agenda for the September 2022 session.
94. The expert from OICA offered to withdraw ECE/TRANS/WP.29/GRVA/2011/9, even though the content of the proposal was still relevant and important for his organization. Similarly, the expert from AVERE withdrew ECE/TRANS/WP.29/GRVA/2021/10. GRVA agreed that the Task Force on ADAS would aim at addressing the matters, too.
95. The expert from OICA introduced ECE/TRANS/WP.29/GRVA/2023/6, as amended by GRVA-15-30. He recalled the context of the proposal, already discussed at the fourteenth session of GRVA. He mentioned that their proposal received comments (GRVA-15-09) and that he addressed them with the amendment included in GRVA-15-52. The secretariat read the letter of the expert from Sweden, absent, who expressed support for ECE/TRANS/WP.29/GRVA/2023/6, as amended by GRVA-15-09.
96. The expert from OICA presented GRVA-15-53 with further provisions for an automatic change to a standby mode. GRVA agreed that a “suitable time delay” was one option to ensure that the vehicle has already reached a regular lane of travel, but GRVA could not identify a fixed time value and therefore agreed that such value could be subject to agreement between the manufacturer and the technical service during the approval process.
97. Following discussions, GRVA reached agreement on GRVA-15-54 and agreed to note in this report the justification and context related to GRVA-15-53, as summarized in para. 96 above.
98. GRVA adopted ECE/TRANS/WP.29/GRVA/2023/6, as amended by GRVA-15-54, and requested the secretariat to submit it as a supplement to the 03 series and 04 series of amendments to UN Regulation No. 79 (steering equipment) to WP.29 and AC.1 for consideration and vote at their June 2023 sessions.
