Proposal to align requirements with technological progress to address steering systems with low steering gear ratios.

95. The expert from Korea, technical sponsor to the amendment to UN GTR No. 8 (see ECE/TRANS/WP.29/2020/99), introduced GRVA-09-36 amending ECE/TRANS/WP.29/GRVA/2020/34, a revised proposal for amendment to UN GTR No. 8 aimed at accommodating new types of steering equipment, low gear systems, not being able to reach the 270 degree request in the sine with dwell test.

96. The expert from Canada expressed reservation with the revised proposal as it would still open the door to safety issues. He explained that the last paragraph of the amendment proposal should only belong to the test procedure and not to the requirement. He explained that this was up to the test facility or manufacturer to perform the test to reach the maximum operable steering angle without overshoot and not for the regulation to accommodate such overshooting risk with a tolerance.

97. GRVA requested the expert from Canada to work together with the expert from Korea so that progress could be achieved until the next session.

83. The expert from Korea, technical sponsor to the amendment to UN GTR No. 8 (see ECE/TRANS/WP.29/2020/99), recalled the purpose of ECE/TRANS/WP.29/GRVA/2020/34 (as amended by GRVA-09-36), a revised proposal for amendment to UN GTR No. 8 aimed at accommodating new types of steering equipment, low gear systems, not being able to reach the 270 degrees request in the sine with dwell test.

84. GRVA noted the oral report from the expert from the Republic of Korea on their consultations with Canada and OICA regarding the amendment proposal to UN GTR No. 8.

85. The expert from Canada provided oral comments on the amendment proposal to the GTR, that the secretariat reproduced in GRVA-11-41.

Proposal to introduce provisions for recently developed steering systems that have significantly lower steering gear ratios (i.e. quick steering characteristics).

59. The expert from the Republic of Korea introduced ECE/TRANS/WP.29/GRVA/2020/34 proposed in accordance with ECE/TRANS/WP.29/2020/99 that provides the authorization to develop an amendment to UN Global Technical Regulation (UN GTR) No. 8. The experts from the USA inquired how the amendment to UN GTR No.8 would solve the issue raised. The expert from the Republic of Korea recalled the context of the proposal, addressing new steering systems with low gear rations. The expert from OICA recalled that this technical discussion took already place under the 1958 Agreement. The expert from Canada offered comments (GRVA-07-64) and questioned the need for a tolerance. He stated the need to verify the impact on safety of such proposal. The experts from the USA and the Netherlands advised to start future activities of this nature under the 1998 Agreement, first.

60. GRVA agreed to resume discussion on ECE/TRANS/WP.29/GRVA/2020/34 (or on a revised proposal) and on the report corresponding to this amendment at its next session.

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

149. The representative of the Republic of Korea presented the work progress on an amendment to UN GTR No. 8. He recalled that AC.1 adopted, at its June 2020 session, amendments to UN Regulation No. 140 (ESC) for allowing new innovative steering systems which have a significantly lower steering gear ratio. He added that, for the sake of keeping the consistency between the UN Regulation No. 140 and UN GTR No. 8, the Republic of Korea had submitted a proposal for amendments to UN GTR No. 8 at the September 2020 GRVA session. He recalled that the proposal submitted received comments from Canada and that no consensus had been reached so far. He explained that there had not been a heightened sense of urgency for completion of this work as this new technology was not yet deployed on the market.

150. The delegate from the United States of America explained that he had similar views as delegates from Canada and proposed the organization of consultations involving the interested stakeholders. The representative of the Republic of Korea welcomed this initiative, and informed stakeholders that attempts would be made to organize consultations before the end of September 2021.
