| Summary | 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. | ||||||||||||||||

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:
Paragraph 5.3.1.6. (former), renumber as 5.3.1.7. 51.

GRRF adopted the proposal as reproduced below: Insert a new paragraph 5.3.1.6., to read:
Paragraph 5.3.1.6. (former), renumber as 5.3.1.7. 53. GRRF requested the secretariat to submit both adopted proposals to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 79. |
