51. Referring to GRRF-78-27, the expert from CLEPA, on behalf of CLEPA and OICA, introduced ECE/TRANS/WP.29/GRRF/2015/37 proposing to align the requirements to be met in case of the steering system and the braking system of a vehicle share the same energy source with those of Regulations Nos. 13 and 13-H. GRRF adopted the proposal as reproduced below:
Insert a new paragraph 5.3.1.6., to read: | “5.3.1.6. | The requirements for the braking performance in paragraphs 5.3.1.4. and 5.3.1.5. above shall not apply if the braking system is such that in the absence of any energy reserve it is possible with the service brake control to achieve the safety requirement for the secondary braking system mentioned in: | | (a) Paragraph 2.2. of Regulation No. 13-H, Annex 3 (for M1-, N1-vehicles);
(b) Paragraph 2.2. of Regulation No. 13, Annex 4 (for M2-, M3-, N-vehicles).” |
Paragraph 5.3.1.6. (former), renumber as 5.3.1.7.

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 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”.

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.
