Concerns over the need to adapt UN R79 to technological progress

Document GRRF-74-37

18 February 2013

74th GRRF session (19-22 Feb 2013)

Current wording of UN R79 prevents the approval of positive steering of trailers using energy supply and electrical control from the towing vehicle because standards applicable to energy supply connectors and digital information interchange have not been established.

Submitted by CLCCR

Status: Superseded

75th GRRF session (17-19 Sep 2013)

3. (c) | Clarifications

9. (a) | Regulation No. 79

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.

9. (b) | Lane Keeping Assist System (LKAS) and Parking Assist Systems (PAS)
