Proposal to align the text with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.

Proposal to include three-wheeled category l vehicles within the scope of ABS testing under UN R78. This would align the scope with EU Directive 93/14/EEC.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

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.

Revised proposal by Italy to introduce requirements for the approval of replacement brake discs for L-category (motorcycle and related) vehicles pursuant to comments received at the September 2014 GRRF session.

Proposal to clarify the text in order to avoid additional administrative and financial costs to the applicant due to misinterpretation of the intent of the text.

Working document of the 2nd ACSF informal group session with session changes highlighted.

Comments on document ACSF-03-03. In particular, the document raises the question of whether the proposed amendments should address software validation, the eventual use of external data from infrastructure or V2V sources, and responses to system/driver response failures.

Spreadsheet tool to calculate safety distances between vehicles as a function of speed and required braking distances.

Proposal for modifications to document ACSF-03-03 to enable the type approval of automated steering functions operating at speeds greater than 10 km/h.

Proposal for modifications to document ACSF-02-03 submitted by Germany to enable the type approval of automated steering functions at speeds greater than 10 km/h.

Input for the draft amendment to UN R79 to enable the type approval of automatically commanded steering functions for use at speeds above 10 km/h.
