This supplement would introduce provisions for fully automatic coupling systems and clarify references in the regulation to Regulation No. 10 on electromagnetic compatibility. This proposal combines two distinct proposals (document GRRF/2013/12 as amended by Annex II to the GRRF 75th session report and document GRRF/2013/13 not amended) approved by the GRRF at its September 2013 session.

Proposal of the ad hoc expert group on transitional provisions to clarify and update these terms within the heavy 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.

Proposal to permit greater discretion in the performance of the fade tests should track safety considerations warrant. In view of several fatal accidents, the test tracks are concerned over requirements to bring the vehicle to a full stop repeatedly and rigidity of the requirement for 15 snubs in quick succession;

Revisions to document GRRF/2013/28 intended to simplify the transitional provisions.

Presentation of issues regarding the UN R13-H provisions on complex electronic control (CEL) systems and the proposals to separate electronic stability controls (ESC) and brake assist systems (BAS) from the light vehicle braking regulation. Since ESC and BAS are subject to CEL provisions, this raises a question on how best to apply CEL across what would be three separate regulations (13-H, ESC, and BAS).

Proposal to require a vehicle sticker showing a diagram of the brake reference forces to facilitate their use in periodic technical inspections.

Suggested changes to the proposal to introduce the concept of “revision of approvals” into the UN Regulations under GRRF responsibility in order to align the UN Regulations with the EU Whole Vehicle Type Approval Directive 2007/46/EC.

Text prepared by the International
Organization of Motor Vehicle Manufacturers (OICA) and the European Association of Automotive Suppliers (CLEPA) to effect an extensive set of corrections and clarifications to formulas and references used UN Regulation No. 13, based on document GRRF-74-31.

Text prepared by the informal working group on Automated Connections between Vehicles (ACV) to introduce automatic coupling systems into UN Regulation No. 13.

Correction to ISO reference since Byte 3-4 of EBS 11 is only referenced in Part 2 of ISO 11992 and therefore the text should make explicit that reference along with amendment 1:2007. Also proposes to omit several redundant footnotes and references.

OICA notes the change in name of “ASTM” to “ASTM International”.

Supporting document to the proposal from the informal working group on Automated Connections between Vehicles concerning the referencing of ISO13044-2:2013 in the proposed amendments to UN Regulation No. 13.

Proposal for collective amendments of amendments to Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

Draft text of amendments to UN R13 to enable the use of automatic coupling systems pursuant to the deliberations of the 12th ACV informal group session.

Jost input for the automated couplings classifications proposal.

Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at 74th session to correct the Russian-version text.

Text as adopted by the Working Party on Brakes and Running Gear (GRRF) at its 74th session to clarify the requirements in Annex 21 of UN R13 on the use of EVSC simulation, to correct a “copy and paste” mistake concerning a signature requirement made when copying text from Annex 11 into Annex 12, Appendix 4, and to harmonize UN R13 with the Federal Motor Vehicle Safety Standard FMVSS 135 on electric vehicle requirements with regard to the regenerative braking system (RBS).

Text prepared by the Netherlands to suggest improvements and simplifications of the transitional provisions in UN Regulations 13 and 13H.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to remove the ESC control and tell-tale requirements from Regulations Nos. 13 and 13-H to Regulation No. 121 and to review the transitional provisions of both Regulations 13 and 13-H.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to introduce the concept of “revision of approvals” into regulations under GRRF responsibility.

The UN R13 and 13-H include procedures to filter out the effects of electric regenerative braking systems from the braking assessment. This proposal would allow test services to disconnect to RBS prior to running tests. It also would allow the use of DC Ampere-hour meter to measure charge states.

Several vehicle control regulations refer to compliance with UN Regulation No. 10 on electromagnetic compatibility. The proposal would revise these references to focus only on the technical (thus excluding administrative) requirements since some countries do not apply UN R10.

Proposal that would correct and clarify provisions within Annex 10 that apply not only to category O2 and O3 trailers, but also, as intended, to category O4 trailers.
