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.

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.

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.

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 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.

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 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.

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.

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.

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

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).

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.

Correction of errors in the proposal of the ad hoc expert group on transitional provisions to clarify and update these terms within the light braking regulation, including provisions for extensions of type approvals granted according to the antecedent requirements of the original approval. These amendments also relate to the transfer of brake-related telltale provisions to UN R121. The proposal notes the deletion of two pictograms referencing electronic stability controls (ESC).

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).

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.

Proposal to clarify provisions on the use of Combined Braking Systems (CBS) and make some additional editorial improvements. This document contains GRRF/2014/05, GRRF/2014/06, GRRF-76-36 Rev 1 and updated by the comments raised at the seventy-sixth GRRF session.

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.

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.

Explanation of OICA’s requests to exempt certain vehicles from mandatory AEBS and/or LDWS requirements due to their uses and the technical limitations of these systems. For example, the sensors used by the systems cannot operate reliably on certain special purpose equipment (such as snow plows) where the equipment and the nature of the operating environment are prohibitive.

Proposal to modify the introductory comments of the LDWS regulation in order to emphasize the focus on highway driving and impracticality of deploying LDWS on certain types of vehicles such as off-road equipment or special purpose vehicles.

Proposal to modify the scope of the regulation in order to exempt certain vehicles from mandatory compliance with its provisions in cases where technical obstacles prevent the reliable use of lane-departure warning systems given the current state of the technology. This document includes a detailed explanation of the vehicle categories for exemption.

Vehicle manufacturers are currently implementing AEBS on a large variety of models, e.g. to fulfil mandatory requirements of some Contracting Parties. This implementation work confirms the concerns which were brought up for discussion during the AEBS/LDWS informal group activities and sheds light on a number of technical issues that appeared when installing obstacle detection devices on some specific vehicles, in particular in case of huge technical diversity and where the vehicle environment can have negative impact on system reliability and on its ability to operate. This proposal would alter the regulation scope to exempt such vehicles from mandatory compliance.

Supporting explanation for the proposal to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.

CLEPA proposed a framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations. This proposal revises the wording, focusing on ESC systems with relation to the requirements for complex electronic control systems under Regulation 13-H.

For testing purposes, UN R90 defines a “test group” as a grouping of parts having the same characteristics. The regulation then defines a “variant” as a part within a “test group”. However, the approval numbers under the rule stipulate the identification of each variant certified. As a result, the text technically requires certification of each individual part (variant) which was not the intention of the drafters. CLEPA raises this for information purposes with the intention to put forward a proposal at the next GRRF session.

IMMA comments on the suggestion to include a cross reference to UN R10 in UN R78 in order to ensure that electromagnetic interference does not affect electronic brake modules in a way that causes unsafe brake operation as was adopted for UN R13.

Text prepared by the experts from the LKAS small drafting group to introduce new definitions and the related LKAS requirements in to the text of UN Regulation No. 79.

Proposal to add a maximum supply line pressure of 900kPa when the compressor is at cut-out during testing of electronic braking systems (EBS). The aim is to prevent trailer EBS failure warnings/shut downs when detecting excessive supply line pressure.

Proposal to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle.

Proposal to clarify the definition of a “variant” in order to avoid unintended interpretations of the certification requirements that could result in additional financial and administrative costs. As currently worded the approval of a Test Group requires individual certification for each part contained within the Test Group. Some Test Groups can contain in the region of 30 part numbers. This would align the practice for brake discs and drums with that for brake linings.

This proposal adds text adopted during the December 2014 LKAS group session that will need to be incorporated, likely through an informal document, to the formal text submitted to the GRRF (document GRRF/2015/2).

The LKAS group proposes several options for the transitional period for consideration and eventual decision by the GRRF. Industry proposes a three-year period before entry into effect while some government representatives propose immediate entry into effect for new type approvals since they believe current LKAS systems already meet the requirements.
