Final report on the development of Amendment 2 to the GTR on motorcycle braking submitted for consideration and approval by the World Forum.

This proposal is presented by the Chair of the Lane Keeping Assistance System (LKAS) adhoc group in order to improve the wording of document ECE/TRANS/WP.29 /GRRF/2015/2, and to resolve pending questions with regard to the warning provision. The group was not able to achieve consensus on the application dates of the amendments (wording remaining in square brackets).

This proposal of the IGCMS-II amends the provisions on steering equipment according Regulation 79 to include vehicles equipped with devices for indirect vision such as camera-monitor devices. Various steering effort test provisions depend on the turning circle which currently excludes external mirrors. The text is amended to exclude as well external camera’s for camera-monitor devices. The proposal would replace the reference to rear-view mirrors with the term “devices for indirect vision” to encompass exterior CMS devices.

Presently, it is not fully clear whether an anti-lock braking system (ABS) switch-off or altering mode is permitted on L-category vehicles, whereas it is clearly not allowed on other vehicle categories. This proposal is aimed at ensuring a consistent approach for all motor-vehicles equipped with anti-lock braking systems, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13.

Discussions have arisen within GRRF concerning failure warnings for trailer direction indicators and brake lights. This paper alerts GRE to the absence of a standardized approach to communicating such lighting failures for trailers which may be a subject for consideration under UN R48.

This is a copy of the proposal submitted to the GRRF (i.e., document GRRF-78-14) to introduce lane-keeping assistance systems (LKAS) into the UN Regulation No. 79. In particular, this relates to the current UN R79 provision that limits automatic steering functions from operating at speeds above 10 km/h.

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 clarify and align the wording of Regulations Nos. 79, 13-H and 13.

The current text of Annex 3 of UN Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4.), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13-H. Paragraph 1.1.2. of Annex 4 to Regulation No. 13-H requires the capacity of a certain number of sudden stops after the energy source failed ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.2.

The current text of Annex 3 of Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13. Paragraph 1.1.3. of Annex 7 to Regulation No. 13 requires the capacity for the system of a certain number of sudden stops, after the energy source failed, ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.3.

The current text of the provisions in Regulation No. 79 could be interpreted as the required number of sudden stops that must be achieved irrespective of the service braking design, i.e. even in the case of assisted braking system.

IMMA wishes to make the wording more technology-neutral, clarify test conditions considered impractical, and allow time for manufacturers to comply (i.e., add transitional provisions).

Proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts.

This work originates from a 2009 draft proposal to amend UN R13.

Comments on the draft amendment to UN R79 addressing automated steering as it stood at the end of the third ACSF informal group session. This document also raises links to rear vision (UN R46), AEBS (UN R131), and park assist systems.

Presentation proposing a requirement for defensive braking on vehicles equipped with ACSF because automated steering may result in driver inattention and therefore require compensating environment monitoring and automatic braking. This type of “protective braking” is viewed as a different order of braking than AEBS given that the principle involves maintaining of distances and avoiding accidents at speed rather than as an emergency or abrupt braking.
