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This document addresses the ramifications of introducing the proposals outlined in GRRF-72-07 (superceded by GRRF-72-07/Rev.1) specifically associated with semi-trailers.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

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.

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”.

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.
