Presentation of the recommendations (see document GRRF/2014/7) of the expert group reviewing the transitional provisions of UN R13 pursuant to the decision to transfer the provisions on the electronic stability control (ESC) warning signal to UN R121 on controls and tell-tales. UN R13 contains 23 transitional provisions introduced to allow manufacturers to adapt to changes that have been made to the rule over time. The ad hoc expert group was formed to streamline these provisions by removing obsolete provisions and by applying uniform language.

Presentation of the recommendations (see document GRRF/2014/16) of the expert group reviewing the transitional provisions of UN R13-H pursuant to the decision to transfer the provisions on the electronic stability control (ESC) warning signal to UN R121 on controls and tell-tales. UN R13 contains eight transitional provisions (five of which are obsolete) introduced to allow manufacturers to adapt to changes that have been made to the rule over time. The ad hoc expert group was formed to streamline these provisions by removing obsolete provisions and by applying uniform language.

Presentation to explain OICA and CLEPA view that lane-keeping assist systems are not presently an appropriate subject for the development of a new regulation.

Analysis based upon data from the Swedish Traffic Accident Data Acquisition System (STRADA) to inform decision-making on future road safety targets and performance indicators.

Draft list of LKAS regulatory provisions pursuant to the discussions held during the first LKAS expert group session as prepared by the group secretary.

Complete draft of the new version of the regulation on heavy-duty braking prepared by the GRRF secretariat. This text includes Supplement 10 which clarifies the requirements in Annex 21 of UN R13 on the use of EVSC simulation, corrects a “copy and paste” mistake concerning a signature requirement made when copying text from Annex 11 into Annex 12, Appendix 4, and harmonizes UN R13 with the Federal Motor Vehicle Safety Standard FMVSS 135 on electric vehicle requirements with regard to the regenerative braking system (RBS).

Report of the 19-20 November 2013 special meeting to discuss whether to pursue a Japanese proposal to develop a new regulation for the approval of lane-keeping assist systems.

Proposal to specify that safety aspects of ESC systems can be assessed under this new regulation or under UN R13-H. 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.

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.

Proposed amendments to UN R13-H to confirm that the complex electronic control system (CEL) requirements may be satisfied through an approval conducted under another regulation (e.g., the pending new ESC and BAS regulations) and to delete the marking requirement concerning ESC systems which will no longer be within the scope of UN R13-H.

Explanation of Dutch concerns with the IMMA proposals on the measurement of brake efficiency and the use of a representative vehicle for testing.

Proposal to specify that safety aspects of brake assist systems can be assessed under this new regulation or under UN R13-H. 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 BAS 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 BAS regulation.

Proposal to clarify and align the text of UN R13 on heavy-duty braking with that of UN R107 on bus construction with regard to the exemption of articulated buses and coaches from the requirements for vehicle stability equipment. The text would specify that “Class I, Class A and articulated vehicles of categories M2 and M3” are exempted from the requirements.

Proposal to amend the draft text for the proposed new regulation on ESC which would extract the ESC provisions from the current UN R13-H on light vehicle braking systems. The intention is to clarify the meaning of the text in places where it is ambiguous when taken out of the context of UN R13-H.

Proposal to amend the draft text for the proposed new regulation on BAS which would extract the BAS provisions from the current UN R13-H on light vehicle braking systems. The intention is to clarify the meaning of the text in places where it is ambiguous when taken out of the context of UN R13-H.

Status report, including the current state of the draft text, on efforts to reach agreement on the introduction of provisions for electro-hydraulic systems into the test conditions for trailers with electrical braking systems.

Proposed corrections and clarifications to the draft text of the new regulation to separate ESC provisions from Regulation No. 13-H (document GRRF/2014/12).

India noted an erroneous reference to “ESC” in the original document where “BAS” was clearly intended.

Request from the chair of the former informal group on automated couplings between vehicles for a mandate to develop amendments to braking, steering, vehicle stability, couplings, and possibly other areas related to modular vehicle combinations either through a new working group or an existing one (e.g., the R55 informal group). The aim would be to enable type approval of components used in vehicle combinations.

India supports the purpose of the amendments to GTR No. 3 (GRRF/2014/4) and UN R78 (GRRF/2014/5) to provide same safety in the case of a failure in CBS as that of the conventional system of the two independent brakes for two wheelers. 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.

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.

Explanation of three options developed for handling the approval of electronic stability controls (ESC) and brake-assist systems (BAS) under regulaitons separate from UN R13-H (light vehicle braking) while fulfilling the requirements of complex electronic systems (CEL).

Reformatted 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.
