GRRF-76-37/Rev.1 | Annotated provisional agenda for the 76th GRRF session Agenda updated by the GRRF secretariat with the latest informal document additions.

GRRF-76-15 | Proposal for Supplement 1 to the 00 series of amendments to Regulation No. 130 Proposal to include a footnote in the scope of the regulation alerting type approval authorities to the possibility for exemptions to the lane departure warning systems requirements based upon reasonable technical feasibility, cost/benefit, and/or other evidence. The broad notion is that LDWS is intended to prevent accidents due to inattention while driving long distances, especially on highways. Therefore, vehicles designed for purposes not given to such monotonous long-distance travel should, under this proposal, logically be exempted on a case-by-case basis from LDWS requirements.

The broad notion is that AEBS is intended to prevent accidents due to inattention while driving long distances, especially on highways. Therefore, vehicles designed for purposes not given to such monotonous long-distance travel should, under this proposal, logically be exempted on a case-by-case basis from AEBS requirements.

GRRF-76-17/Rev.1 | Proposal for Supplement 02 to the 01 series of amendments to Regulation No. 131 Proposal to include a footnote in the scope of the regulation alerting type approval authorities to the possibility for exemptions to the automatic emergency braking systems requirements based upon reasonable technical feasibility, cost/benefit, and/or other evidence. The broad notion is that AEBS is intended to prevent accidents due to inattention while driving long distances, especially on highways. Therefore, vehicles designed for purposes not given to such monotonous long-distance travel should, under this proposal, logically be exempted on a case-by-case basis from AEBS requirements.

The Russian Federation has developed a “Deceleration Calculator” for use in the UN R117 procedures. Following work by an ad hoc group (including NAMI, UTAC, and ETRTO) formed to review and validate this tool, Russia has prepared this new proposal, modifying the version (document GRB/2013/10) submitted at the last GRB session.

The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed ESC regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the ESC regulation.

GRRF-76-42 | Proposal for amendments to Regulation No. 90 Proposal to clarify that like original brake discs and drums, original brake lining assemblies & drum brake linings are also not subject to this regulation and to refine the definition of "m_axle" as the "maximum technically" permitted mass of the axle in alignment with the definition in Annex 11-Appendix 1, Table 1 of UN R13.

GRRF-76-36/Rev.1 | Proposal for amendments to ECE/TRANS/WP29/GRRF/2014/5 Proposal to clarify the intent of the selected paragraphs to ensure that systems with with one service brake meet braking performance requirements using only that brake system (i.e, without any assistance from the secondary brake system). There had been an interpretation that for systems with two service brakes each brake had to meet the requirements which would result in higher stringency levels than intended by the requirement for single brake systems. The proposal also clarifies the parts of the braking system that should be considered with respect to hydraulic brake and mechanical transmissions and further clarifies that the test procedures are designed to simulate a brake failure rather than produce one.

However, India believes the application of the amendments to three-wheelers requires additional consideration. Therefore, in order to proceed with amendments concerning CBS for two-wheelers, India proposes changes to the proposed text in order to allow further consideration of three-wheelers.
