Text prepared by Germany to clarify electrical braking system and energy supply line requirements with regard to towed trailers, including proposals for voltage specifications and inclusion of electro-hydraulic transmission devices within such systems. The text also seeks to align terminology with comparable paragraphs in other UN Regulations.

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.

Status report, including the current state of the draft text, on efforts to reach agreement on the introduction of provisions for electro-hydraulic systems into the test conditions for trailers with electrical braking systems.

Proposal to introduce new requirements for trailers braked by an inertia (overrun) braking system.

Status report, including the current state of the draft text, on efforts to reach agreement on the introduction of provisions for electro-hydraulic systems into the test conditions for trailers with electrical braking systems.

Proposal for amendments to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

Proposal to remove all references to Annex 10 from Annex 13 by transferring the provisions concerning vehicles with and without anti-lock braking systems to Annex 10.

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.

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.

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.

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.

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.

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.
