Change to the proposed text pursuant to agreement within the “LKAS Small Drafting Group” concerning the “means of detecting that the driver is likely to be no longer in primary control of the steering system” and related driver warning method(s).

Proposal to introduce lane-keeping assistance systems into the regulation. This document incorporates the agreed-upon definitions presented in document GRRF-78-05.

Proposal to introduce general performance guidelines into the annex on automated driver assistance systems in order to set initial safety considerations to guide the commercialization of this emerging technology.

Copy of a 2009 draft proposal to amend Regulation No. 13 to specify uniform requirements for towing trailers and motor vehicles which may tow more than one trailer (road train combinations).

Proposal to clarify the draft text to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.

Explanation of OICA’s requests to exempt certain vehicles from mandatory AEBS and/or LDWS requirements due to their uses and the technical limitations of these systems. For example, the sensors used by the systems cannot operate reliably on certain special purpose equipment (such as snow plows) where the equipment and the nature of the operating environment are prohibitive.

Proposal to modify the introductory comments of the LDWS regulation in order to emphasize the focus on highway driving and impracticality of deploying LDWS on certain types of vehicles such as off-road equipment or special purpose vehicles.

Proposal to modify the scope of the regulation in order to exempt certain vehicles from mandatory compliance with its provisions in cases where technical obstacles prevent the reliable use of lane-departure warning systems given the current state of the technology. This document includes a detailed explanation of the vehicle categories for exemption.

Vehicle manufacturers are currently implementing AEBS on a large variety of models, e.g. to fulfil mandatory requirements of some Contracting Parties. This implementation work confirms the concerns which were brought up for discussion during the AEBS/LDWS informal group activities and sheds light on a number of technical issues that appeared when installing obstacle detection devices on some specific vehicles, in particular in case of huge technical diversity and where the vehicle environment can have negative impact on system reliability and on its ability to operate. This proposal would alter the regulation scope to exempt such vehicles from mandatory compliance.

Proposal to modify the introductory comments of this regulation to explain the rationale for the exemption of certain vehicles from mandatory compliance with its requirements.

Proposal to modify the introductory comments in this regulation in order to explain the rationale behind the exemption of certain vehicles from mandatory compliance with its requirements.

Proposal to delete Annex 7 from the draft ESC regulation and replace the procedure for validating the test (road) surface condition with a reference to Appendix 6 to Annex 2 of UN R13-H. This change would ensure that the ESC regulation fully aligns with UN R13-H and with GTR No. 8 on ESC systems.

Presentation discussing the framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations.

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.

Supporting explanation for the proposal to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.

CLEPA proposed a framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations. This proposal revises the wording, focusing on ESC systems with relation to the requirements for complex electronic control systems under Regulation 13-H.

For testing purposes, UN R90 defines a “test group” as a grouping of parts having the same characteristics. The regulation then defines a “variant” as a part within a “test group”. However, the approval numbers under the rule stipulate the identification of each variant certified. As a result, the text technically requires certification of each individual part (variant) which was not the intention of the drafters. CLEPA raises this for information purposes with the intention to put forward a proposal at the next GRRF session.
