Excerpts from session reports

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 GRVA-07-29 superseded by GRVA-07-32.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.

GRVA | Session 9 | 1-5 Feb 2021

49. The expert from OICA introduced ECE/TRANS/WP.29/GRVA/2021/9 as amended by GRVA-09-30. She announced that the amendment to the tolerance in square bracket was withdrawn. GRVA adopted the proposal (without the amendment to the tolerance in para. 5.6.4.7.) and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2021 sessions.

GRVA | Session 14 | 26-30 Sep 2022

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.

GRVA | Session 11 | 27 Sep-1 Oct 2021

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.

GRVA | Session 13 | 23-27 May 2022

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.

GRVA | Session 15 | 23-27 Jan 2023

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.
