Report from the 5th session of the informal working group on Automated Connections between Vehicles working on language to integrate such systems within UN R13 (heavy-duty braking) and UN R55 (mechanical couplings).

Denmark submitted document GRRF-71-19 (subsequently integrated into GRRF/2012/12) proposing to narrow the compatibility bands for control line pressure versus brake rate. This document challenges the proposed changes as effectively mandating electronic braking and imposing unwarranted costs.

Denmark submitted Document GRRF-71-18 (subsequently integrated into GRRF/2012/12) proposing to narrow the limits for coupling force control systems which are allowed to override the compatibility bands. This document argues against the proposed changes.

Denmark submitted GRRF-71-19 (subsequently in GRRF/2012/12) proposing a new paragraph to require a test point between the coupling head and the trailer relay emergency valve. This document argues that the requirement is already implicit within UN R13 and therefore, that the change is unnecessary.

This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.

The current text of UN R107 does not permit flexible straps for restraining rear-facing wheelchairs. CLCCR proposes to permit this option for enhancing wheelchair lateral stability.

Draft report of the 6th meeting of the informal group on automated connections between vehicles, pending approval at the 7th session scheduled for 2 May.

The draft report was revised to specify that “12 to 13m” is the standard EBS cable length on the majority of vehicles. The draft report read only “13m”.

Formal proposal from the European Liaison Committee of the Body and Trailer Building Industry (CLCCR) to ensure the lateral stability of a rearward facing wheelchair by restraint with a rigid device or with a flexible strap anchoring the wheelchair.

Proposal from the International Association of the Body and Trailer Building Industry (CLCCR) to ensure the lateral stability of a rearward facing wheelchair by restraint with a rigid device or with a flexible strap anchoring the wheelchair and its occupant.

Current wording of UN R79 prevents the approval of positive steering of trailers using energy supply and electrical control from the towing vehicle because standards applicable to energy supply connectors and digital information interchange have not been established.

At the 74th GRRF session, CLCCR presented document GRRF-74-37 which noted that a design restriction in UN R79 prevents trailers from using energy from a towing vehicle. Following discussion, a number of delegates indicated their support for an amendment to remove this restriction and enable the use of new technologies.

CLCCR recommendation to establish an expert group to further consider the German proposal to raise rear underrun protection device (RUPD) requirements. CLCCR raises concerns over the cost-benefit and in particular, over the relative effectiveness of higher requirements across the range of vehicle categories that would be affected.

Series of proposals to revise the positioning specifications for direction indicators, marker lamps, and reflectors on trailers (O category) and to make clarifications.

Proposal to enable the approval of positive steering of trailers using energy supply and electrical control from the towing vehicle because standards applicable to energy supply connectors and digital information interchange have not been established.

Proposal to clarify restrictions on the application of an RUPS according to specific vehicle chassis characteristics (e.g., stiffness, profile dimensions) under Annex 1 (item 9) the test set-up Annex 1 item 9 and to adapt the test procedure of Annex 5 (paragraph 1.1.3.) accordingly by the use of representative side rails. The proposal would also specify that the device used to distribute the test force over the stated flat surface be connected to the force actuator through a swivel joint since a wholly rigid set up can result in very different and unintended outcomes.

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.

Correction to document GRRF/2015/8 (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), updating a reference to a paragraph number that has changed.

Amendment to specify the connector through which electrical energy is supplied in the 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 and refine the draft amendments proposed in document GRSG/2015/17 “Proposal for the 03 series of amendments to UN Regulation No. 58”.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

Amendment 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, including specification of the connector through which electrical energy is supplied in the proposal

Document GRRF/2016/20 proposes 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, including specification of the connector through which electrical energy is supplied in the proposal. Although this proposal was approved in principle at the 80th GRRF session, it was agreed that the proposal would be reviewed at the 81st GRRF to define an open value [X] in paragraph 2.1.1. of Annex 5. It has subsequently been concluded that this change to paragraph 2.1.1. is not needed. Therefore, this proposal removes the change to the paragraph from GRRF/2016/20.

Revised approach to resolving the issues raised in Romania’s proposal GRSG/2015/21 to redefine the measurement criteria for determining appropriate seat spacing. This proposal has been developed collaboratively by Romania, OICA, and CCLCR with respect to discussions held by the type approval authorities of the member states of the European Union (TAAM). The proposal includes the use of a new testing gauge for the H dimension measurement.

Proposal to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their use on [traffic] roads may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

Updated proposal, revised for clarity, to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The proposal allows Type Approval Authorities to nonetheless exempt “vehicles where any LPD (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use” through the addition of new paragraphs.

Proposal for withdrawal based on to highlight the broader implications for vehicle design and usability for consumers resulting from this proposal. The lowering of the sideguard and reduction in ramp angle will give reduced flexibility for vehicles and trailer combinations in certain applications (i.e. loading roll-
on, roll-off vessels) and conflict with the road surface and local infrastructure (i.e. grounding out), which will lead to damage or reduced life of sideguards.
