New proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.

Reference prepared by the WP.29 secretariat

Proposals by Germany and the Netherlands to clarify trailer requirements under UN Regulation Nos. 13 and 13-H, including the removal of design restrictions that prevent the use of electro-hydraulic and electro-pneumatic braking systems.

Proposal from Germany to introduce a new Annex 23 into UN Regulation No. 13 covering special additional requirements for trailers of category O2 without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices. In addition, the document proposes to further amend braking requirements for trailers under Regulation No. 13 and 13-H to address these new braking systems.

In the framework of the International Whole Vehicle Type Approval (IWVTA) discussion, it was agreed to split Regulation No. 13-H into three distinct Regulations: on Braking, on Brake Assist Systems (BAS) and on Electronic Stability Control (ESC). In order to complete this task and to ease the implementation work of Contracting Parties relying on the existing text of the Regulation to mandate BAS or ESC, new transitional provisions are proposed.

Proposal to add a trigger threshold requirement and to modify the sampling rate, deceleration limit and data selection criteria for category B brake-assist systems.

Under the International Whole Vehicle Type Approval (IWVTA) program, brake assist systems (BAS) and electronic stability controls (ESC) would be separated from UN R 13-H into new stand-alone regulations. This document has been prepared by an ad hoc group in order to ensure adequate transitional provisions to enable Contracting Parties to adapt to the new approach.
