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.

Proposal to specify that safety aspects of brake assist systems can be assessed under this new regulation or under UN R13-H. The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed BAS regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the BAS regulation.

Proposal to amend the draft text for the proposed new regulation on BAS which would extract the BAS provisions from the current UN R13-H on light vehicle braking systems. The intention is to clarify the meaning of the text in places where it is ambiguous when taken out of the context of UN R13-H.

India noted an erroneous reference to “ESC” in the original document where “BAS” was clearly intended.

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).
