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).

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”.

CLCCR comments on draft proposal on device to break the glass of emergency windows by France and Germany

Text as revised during the 10th BMFE informal group session.

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 permit the installation of manoeuvring lamps on trailers.

Proposal to permit the installation of manoeuvring lamps on trailers and increasing the number currently permitted to be installed on motor vehicles.

Revised proposal to increase the number of manoeuvring lamps on trailers according to the length of the trailer.

Proposal to permit the installation of manoeuvring lamps on trailers.

Proposal to increase the number of manoeuvring lamps on trailers according to the length of the trailer.

Proposal to increase the number of manoeuvring lamps on trailers according to the length of the trailer.

This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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 clarify and refine the draft amendments proposed in document GRSG/2015/17 “Proposal for the 03 series of amendments to UN Regulation No. 58”.

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.”
