9. (a) | Regulation No. 79

48. The expert from CLEPA recalled, on behalf of CLCCR, the proposal ECE/TRANS/WP.29/GRRF/2016/20 previously adopted by GRRF with a scrutiny reservation. CLCCR reviewed the text in square brackets and proposed to delete it as proposed in GRRF-81-13. GRRF adopted the proposal as amended by Annex V to the report and requested the secretariat to submit it together with ECE/TRANS/WP.29/GRRF/2013/13 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.

9. (a) | UN Regulation No. 79

54. The expert from CLEPA introduced on behalf of CLCCR the proposal ECE/TRANS/WP.29/GRRF/2015/43 superseding ECE/TRANS/WP.29/GRRF/2015/8. The proposal received some comments and was amended during the session as reproduced in GRRF-80-40. GRRF agreed with the proposal but preferred to review it again in February 2016 in view of a possible adoption in June 2016 by WP.29 and AC.1.54

9. (c) | Automatically Commanded Steering Functions
8. (a) | Vehicle automation
9. (a) | Regulation No. 79

40. The expert from CLEPA, on behalf of CLCCR, introduced ECE/TRANS/WP.29/GRRF/2014/8 as amended by GRRF-79-02 and GRRF-79-21, aimed at removing a design restriction from Regulation No. 79 that prevents the approval of new technologies. The proposal received some comments. GRRF agreed to resume consideration on this item at its September 2015 session based on a revised proposal that the author volunteered to prepare. The secretariat agreed to consult the Working Party on Lighting and Light-Signalling on the issue of trailer mounted warning light.

9. (a) | Regulation No. 79 (Steering equipment)

40. At the request of the authors of ECE/TRANS/WP.29/GRRF/2014/19, GRRF agreed to withdraw the document. Instead, the expert from CLEPA introduced GRRF-78-44 supporting GRRF-78-27 on requirements to be met in cases where braking and steering systems have the same energy source. The proposed amendment attempted to clarify and align the wording of this UN Regulation No. 79 with that of UN Regulation No. 13-H. Following the discussion, GRRF agreed to revisit this subject at its February 2015 session on the basis of a revised proposal by CLEPA taking into account the comments received.

41. The expert from CLEPA, on behalf of CLCCR, introduced ECE/TRANS/WP.29/GRRF/2014/8 aimed at removing a design restriction from UN Regulation No. 79 that prevents the approval of new technologies. He explained that the proposal was not intended for immediate adoption and he invited all interested experts to send him their comments (colin.ross@meritor.com). GRRF agreed to resume consideration of this matter on the basis of a revised proposal by CLEPA.

37. On behalf of CLCCR, the expert from CLEPA proposed amendments to UN Regulation No. 79 (ECE/TRANS/WP.29/GRRF/2013/25) inserting new requirements for trailers with a steering control system utilising electrical energy from the towing vehicle. The proposal received some comments (GRRF-75-11). The expert from Japan noted the absence of a definition for “IP54”. GRRF agreed to resume consideration of this subject at its next session on the basis of a revised proposal.
