GRRF-73-09

9. The expert from Sweden, chairing the informal group on Automated Connections between Vehicles (ACV), reported on the progress made by the group (GRRF-73-09). The informal group produced the informal document GRRF-73-15 proposing to amend UN Regulation No. 13 with provisions for Automated Connections between Vehicles. Following a discussion on the interoperability and safety provided by such systems, GRRF requested the informal group to provide some clarifications and a risk analysis for consideration at the next session of GRRF.

10. The expert from Sweden sought GRRF’s guidance on the part of the mandate of ACV informal group with respect to road trains. Some governmental experts expressed their wish to work on this matter. The expert from CLEPA reminded GRRF about the existence of GRRF-66-08. This document will be reinserted into the agenda of the next session of GRRF. At the request of the informal group, the chair provided guidance on the prioritization of work, proposing to finish the work on ACV and then to start to work on road trains. In this respect, the chair requested the informal group to review the terms of reference of ACV and to prepare an updated version if necessary.

11. The expert from OICA introduced a proposal for editorial corrections to Regulation No. 13 (GRRF-73-02). GRRF agreed to two of the three proposed changes and adopted the proposal as reproduced in Annex 3 to this report. The secretariat was requested to submit it to WP.29 and AC.1 for consideration at their March 2013 session as Corrigendum 2 to UN Regulation No. 13.

12. GRRF noted the state of discussions in WP.29 on dynamic or static references to other UN Regulations and private standards. GRRF welcomed the recommendation to proceed on a case by case approach. The expert from Japan introduced a proposal to insert in Regulations Nos. 13 and 13-H a reference to Regulation No. 10 and its 04 series of amendments. The experts from OICA and CLEPA proposed to make a reference to the 03 series, as the 04 series only defines new requirements for hybrid electric vehicles (HEV) and electric vehicles (EV) vehicles. OICA recalled the purpose of ECE/TRANS/WP29/GRRF/2011/34 and especially the justification part. GRRF agreed to resume the discussion at its next session. For this purpose, the Chair requested the secretariat to distribute GRRF-73-14 with an official symbol, to keep ECE/TRANS/GRRF/2012/21 and to reinsert ECE/TRANS/GRRF/2011/34 on the agenda.

13. The expert from Belgium recalled the work progress (GRRF-73-09) made by the informal group on AMEVSC proposing updated provisions of Annex 21 (and its appendix) to UN Regulation No. 13 dealing with the use of simulation tools duly validated to prove compliance of the vehicle stability function (ECE/TRANS/WP.29/GRRF/2012/2). The Secretary introduced GRRF-73-06. GRRF was supportive of the proposal but raised some detailed issues. The Chair invited GRRF to provide the Secretary of the informal group with written comments to allow a revision to be prepared as an official document for consideration by GRRF at its next session .

14. The Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2012/11 and GRRF-72-28 on the introduction of an electro-hydraulic transmission for electrical brake systems. The expert from the Netherlands reported on a first meeting with Germany and his intention to produce an enhanced proposal for consideration at the next session. GRRF agreed to resume the discussion at its next session, keeping these documents as a reference.

17. In the absence of the Secretary and the Chair of the informal group on the Regulation No. 55, the expert from Germany informed GRRF about the proposed of terms of reference (TOR) for the informal group as described in the working paper R55-01-02. GRRF agreed to review this document as an informal document at its next session.
