Proposal to align requirements with technological progress to address steering systems with low steering gear ratios.
76. GRVA received an oral report from the expert from the Republic of Korea regarding the development of an amendment proposal to UN Global Technical Regulation (GTR) No. 8 (GRVA-12-13).
77. GRVA noted that following discussions, ECE/TRANS/WP.29/GRVA/2022/12 and ECE/TRANS/WP.29/GRVA/2020/34 were withdrawn by the experts from Canada and the Republic of Korea, respectively.
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.
86. GRVA agreed to resume consideration of this item at its next session.
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.
