Presentation of issues regarding the UN R13-H provisions on complex electronic control (CEL) systems and the proposals to separate electronic stability controls (ESC) and brake assist systems (BAS) from the light vehicle braking regulation. Since ESC and BAS are subject to CEL provisions, this raises a question on how best to apply CEL across what would be three separate regulations (13-H, ESC, and BAS).

Revisions to document GRRF/2013/28 intended to simplify the transitional provisions.

Responses to document GRRF-75-19 detailing OICA’s remaining concerns over the proposal to refine the definition of “identical” discs and drums and to extend this to brake linings.

Proposal to insert missing item in the table of contents.

Corrections to the proposed series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements in UN R78.

Corrections to the proposed series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements.

Proposal to permit greater discretion in the performance of the fade tests should track safety considerations warrant. In view of several fatal accidents, the test tracks are concerned over requirements to bring the vehicle to a full stop repeatedly and rigidity of the requirement for 15 snubs in quick succession;

Proposals for LKAS regulatory provisions.

Presentation on the objectives and considerations behind the proposal to establish technical requirements for lane-keeping assist systems.

Concordance of existing texts from Japan, ISO, UN lane departure warning system (LDWS), and ADAS design principles pertinent to lane-keeping assist systems.

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 transfer electronic stability control 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-75-15.

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 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 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.

Proposal to improve the definition of “identical” parts as applied to replacement brake discs and drums and to introduce an “identical” part definition for brake linings. This documents supersedes document GRRF-75-18.

The proposed amendments would:

a) clarify possible confusion in the interpretation of the terms “inoperative” and “disconnected”;
b) update requirements for combined braking systems;
c) introduce the “K-method”; and
d) introduce the concept of a representative vehicle based on the
provisions of Regulation No. 13-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.

Proposal from the International Motorcycles Manufacturer Association (IMMA) to introduce amendments clarifying the current text on the use of Combined Braking Systems (CBS) into UN R78.

Updated proposal for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements under UN R78.

Proposal from Italy to clarify provisions concerning the use of Combined Braking Systems (CBS) in GTR No. 3.
