Request to develop an amendment to the GTR 8 testing provisions to accommodate the latest innovations for steering systems which have significantly low steering gear ratio (i.e. quick steering characteristics).

64. The representative of the Republic of Korea introduced ECE/TRANS/WP.29/2020/99 requesting an authorization to work to adapt the UN Global Technical Regulation (UN GTR) No. 8 to the technical progress with the aim to amend the testing provisions to accommodate the latest innovations for steering systems. AC.3 endorsed the request and requested the secretariat to distribute with an AC.3 symbol

The objective of this proposal is to develop, in the framework of the 1998 Agreement, an amendment to UN Global Technical Regulation (GTR) No. 8 on Electronic Stability Control to amend to the testing provisions to accommodate the latest innovations for steering systems which have significantly low steering gear ratio (i.e. quick steering characteristics).

5. The Secretary presented GRVA-05-28, with the highlights of the November 2019 session of the World Forum for Harmonization of Vehicle Regulations (WP.29). He highlighted, among others, the question raised by WP.29 to the subsidiary bodies concerning the use of the Unique Identifier in relation with e.g. installation marking provisions. He referred to ECE/TRANS/WP.29/1149 for more details.

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).
