Presentation of the recommendations (see document GRRF/2014/16) of the expert group reviewing the transitional provisions of UN R13-H pursuant to the decision to transfer the provisions on the electronic stability control (ESC) warning signal to UN R121 on controls and tell-tales. UN R13 contains eight transitional provisions (five of which are obsolete) introduced to allow manufacturers to adapt to changes that have been made to the rule over time. The ad hoc expert group was formed to streamline these provisions by removing obsolete provisions and by applying uniform language.

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.

Correction of errors in the 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. The proposal notes the deletion of two pictograms referencing electronic stability controls (ESC).

Explanation of three options developed for handling the approval of electronic stability controls (ESC) and brake-assist systems (BAS) under regulaitons separate from UN R13-H (light vehicle braking) while fulfilling the requirements of complex electronic systems (CEL).

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 transfer brake assist system systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-14.
