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.

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

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.

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.

Different in-use scenarios for automatically commanded steering functions.

Draft agenda for the first meeting of the informal working group on Automatically Commanded Steering Functions.

Proposal from Germany to include automatic steering systems under defined conditions for vehicle speeds above 10 km/h within UN Regulation No. 79.

This is a copy of the document prepared during the third LKAS ad hoc group session (document LKAS-03-09) proposing refinements to the draft amendment to UN R79 that would enable the type approval of lane-keeping systems that incorporate automatic steering functions operating above 10 km/h (document GRRF-78-14).

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.

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.

Reference prepared by the WP.29 secretariat

Proposal to adapt UN R79 in line with the proposed addition of camera-monitor systems to UN R46 (indirect vision). UN R79 refers to external mirrors in test procedures involving the vehicle turning circle. This proposal replaces the reference to mirrors with a broader reference to “indirect vision devices” that includes CMS.

Status of ITS/AD Informal Group consideration of guidance for WP.29 working parties on the regulation of automated driving technologies, especially concerning automatically commanded steering under UN R79.

Proposal to develop regulatory provisions that would enable the approval of automated steering systems (i.e., systems that control vehicle lateral movement) that operate at speeds higher than 10 km/h. The proposal originates from discussions on lane-keeping assistance systems and on automated driving.

Amendment to specify the connector through which electrical energy is supplied in the proposal to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle.
