55. The expert from OICA introduced ECE/TRANS/WP.29/GRVA/2019/22 with amendments to the testing provisions to accommodate the latest innovations for steering systems. The expert from the Republic of Korea proposed clarifications. GRVA noted that this work stream may impact UN GTR No. 8. GRVA agreed to keep UN Regulation No. 140 and UN GTR No. 8 aligned.

56. The expert from OICA presented GRVA-04-44 drafted together with the secretariat, incorporating the proposal of the expert from the Republic of Korea and also identifying the corresponding paragraphs in UN GTR No. 8. The expert from Korea supported the document and announced that his country can volunteer to sponsor an amendment to UN GTR No. 8. GRVA requested the secretariat to distribute this document with an official symbol at its next session.

61. The expert from OICA, recalling the purpose of GRVA-04-44, introduced ECE/TRANS/WP.29/GRVA/2020/12 with an amendment proposal of the normalized angle (A) amplitude requirement when performing the “sine with dwell” test procedure described in UN Regulation No. 140. He explained that this amendment would be necessary as the current requirement was not suitable for some future steering equipment which would have significantly lower steering gear ratios.

62. The expert from the Republic of Korea introduced GRVA-05-11 proposing to keep the text of UN Regulation No. 140 and UN GTR No. 8 aligned. The experts from the United States of America and Canada offered comments and agreed to review the proposal.

63. GRVA adopted ECE/TRANS/WP.29/GRVA/2020/12 as amended by Annex V of the session report (based on GRVA-05-56) and requested the secretariat to submit it to WP.29 and AC.1 as draft supplement to UN Regulation No. 140 for consideration and vote at their June 2020 sessions. GRVA supported the initiative of the Republic of Korea. GRVA invited the representative of the Republic of Korea to proceed with the submission of an authorization request to amend UN GTR No. 8 at the next session of the Executive Committee of the 1998 Agreement (AC.3).

Proposal to allow for the use of the maximum operable steering wheel angle of a steering system’s design in cases where the normalized angle as calculated under the regulation cannot meet the fixed values of the regulation (i.e., between 270 and 300 degrees). The intention is to enable approval of eventual systems (e.g., steer-by-wire) that may use low steering gear ratios.
