Previous Discussion(s)

Working Party on Brakes and Running Gear | Session 73 | 18-20 Sep 2012

2. GRRF adopted the agenda ECE/TRANS/WP.29/GRRF/2012/15, its Add.1 and the running order GRRF-73-01 without changes.

3. The expert from the EC reported on the progress made by the informal group on Advanced Emergency Braking Systems (AEBS). He presented an amendment to the Terms of Reference (AEBS-LDWS-01-07-Rev.3) necessary for completing the second step of work by the Informal Group. GRRF endorsed this amendment as reproduced in Annex II to this report. He reminded the Working Party that ECE/TRANS/WP.29/2011/92/Amend.1 and ECE/TRANS/WP.29/2011/93/Amend.1 were listed on the agenda of the November 2012 session of WP.29. He expected that the European Union would be in position to vote at that session.

4. GRRF noted that the informal group resumed its work on technical requirements on AEBS for vehicles of the category N2 below eight tons as well as the category M2. OICA presented their review of the issues associated with applying the technology to these vehicle classes noting the lack of real world experience (AEBS-LDWS-17-02-Rev.1). The expert from the EC reminded GRRF about the tight time line and the necessity to produce an informal document before the next session of GRRF to finish the work on time. GRRF noted the intention of the informal group to convene again in Paris on 7 December 2012 and in Geneva on 18 February 2013.

No report

5. The expert from OICA noted the lack of support for GRRF-72-02 and withdrew the document. GRRF agreed to remove this item from the agenda.

6. The Chair of the informal working group on “Alternative Method to assess the Electronic Vehicle Stability Control system” (AMEVSC) reported on the progress made by the group on the use of test reports according to Annex 19 of UN Regulation No. 13. He underlined the discussion that took place within the group on the rights and obligations when using a procedure of test reports linked to the 1958 Agreement and noted the progress made in understanding the differing acceptance of test reports by Contracting Parties. He volunteered to prepare an informal document for the next session of GRRF, providing answers to the questions raised during the discussion. The expert from CLEPA withdrew GRRF-72-17.

7. The expert from Denmark informed GRRF about the outcome of an informal meeting held in Brussels on 26 June 2012 dealing with the truck and trailer brake compatibility, coupling force control, and test points for Periodical Technical Inspections (PTI). He advised that the experts from OICA and CLEPA had provided the group with information about the functionalities of a coupling force control device. The group had noted that some studies have been done prior to the entry into force of the recent provisions on compatibility of truck and trailer brakes. The group had concluded that some time was necessary to permit the market penetration of the new technologies required by the latest series of amendments to UN Regulation No. 13. The group had concluded that the problem raised by Denmark is expected to be resolved as the new provisions in UN Regulation No. R13 take effect.

8. GRRF decided to remove this item from the agenda.

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.

15. GRRF had noted during its last session the submission to WP.29 by the Working Party on General Safety Provisions (GRSG) of ECE/TRANS/WP.29/2012/30 proposing to remove the ESC tell-tale requirements from UN Regulations Nos. 13 and 13-H and to insert these requirements into UN Regulation No. 121. GRRF had supported the text proposed in ECE/TRANS/WP.29/GRRF/2012/14. The experts from the Russian Federation and OICA proposed to clean up the transitional provisions and introduced GRRF-73-19 and GRRF-73-24, summarizing the transitional provisions of UN Regulations Nos. 13-H and 13 including explanations and useful details. The expert from OICA agreed to prepare an official document on the basis of these proposals for consideration at the next GRRF session. The Chair underlined the need for simultaneous adoption of amendments by WP.29 and AC. 1 and therefore suggested to keep ECE/TRANS/WP.29/2012/30 on the agenda of WP.29, awaiting the adoption by GRRF of amendments to Regulations Nos. 13 and 13-H. He expressed his intention to inform WP.29.

16. The expert from OICA presented ECE/TRANS/WP.29/GRRF/2012/16 to align Regulation No. 13-H with FMVSS 135 on electric vehicle requirement with special regard to the regenerative braking system. GRRF supported, in principal, the proposal and noted some comments. GRRF agreed to resume consideration of this subject at its next session.

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.

Please see item 5(b) for the discussions of this item.

18. The expert from IMMA introduced GRRF-73-10 proposing to clarify some provisions, simplify the test procedures in UN Regulation No. 78. IMMA also introduced GRRF-73-11 proposing similar amendments to the test procedures in GTR No. 3. GRRF noted the intention and provided some immediate comments. GRRF also noted that an amendment to the GTR will require the sponsorship of a Contracting Party to the 1998 Agreement before the proposal is transmitted to WP.29.

19. The expert from IMMA invited all GRRF experts to submit their comments by email (grrf@unece.org). He volunteered to prepare revised proposals, taking into account the comments received for consideration as official documents at the next session of GRRF.

20. The expert of FEMFM introduced GRRF-73-04 taking into account some remarks received during the last session of GRRF. He recalled the purpose of the proposal and underlined that so called “chemically and physically identical replacement brake lining assemblies” and “chemically and physically identical drum brake linings” should not have to be tested but should be approved on the basis of the homologation of the original equipment supplier. In that case, the applicants for approval should only demonstrate that they supply the brake lining assemblies or the drum brake linings for the vehicle or brake manufacturer as original equipment for the specific model/models for which approval is being sought, and that they produce the parts under the same production conditions, quality assurance system, and with the same results of the conformity of production tests as for the original parts.

21. The expert of Spain reported some weaknesses in a similar case (for discs and drums), where this type of provision was already in force. Based on this experience, he underlined the need to be precise. He added, the goal is to make sure that only original manufacturers can use this procedure. GRRF reviewed the wording of the informal document and the expert of FEMFM invited GRRF to send him any further contributions to allow him to submit in due time an updated wording in the form of an official document for consideration at the next session of GRRF.

No report

22. The expert from France introduced GRRF-73-03 proposing the technical report on the development of the tyre GTR. GRRF noted a number of comments. The expert from France volunteered to submit a revised proposal for consideration at the next session of GRRF as an official document.

23. The secretary of the tyre GTR informal group reported on the progress made. He presented the text of a draft GTR (ECE/TRANS/WP.29/GRRF/2012/22) which GRRF partially reviewed, taking into account the amendments proposed in GRRF-73-12, GRRF-73-13, GRRF-73-22 and GRRF-73-25. GRRF agreed that the informal group should continue to work on the draft GTR and to hold their next meeting immediately before GRRF on Monday 18 February 2013. From this meeting GRRF anticipate an updated final text for adoption during its 74th session.

24. GRRF agreed to consider this subject together with item 7(d).

25. The expert from ETRTO presented a minor amendment to UN Regulation No. 106 (ECE/TRANS/WP.29/GRRF/2012/20). GRRF adopted this document and requested the secretariat to submit it to WP.29 and AC. 1 as Supplement 10 to UN Regulation No. 106.

26. The Chair recalled the purpose of ECE/TRANS/WP.29/2012/54 harmonizing the definitions of “snow tyres” and “snow tyres for use in severe snow conditions” in UN Regulations Nos. 30, 54 and 117, for further consideration by GRB. The Chair of GRB presented GRRF-73-05, a proposal generated by GRB during its session in September 2012 which slightly modifies the GRRF proposal. GRB preferred to remove the marking M+S from UN Regulation No. 117. Only “snow tyres for severe condition” with the “Alpine Marking” are entitled to the bonus on limit values set in the Regulation (e.g. for “rolling noise”). GRRF endorsed the proposal by GRB as reproduced in GRRF-73-05-Rev.1 and agreed to submit it to WP.29 and AC.1 for consideration at their November 2012 sessions together with ECE/TRANS/WP.29/2012/54 as Supplement 02 to the 02 series of amendments to UN Regulation No. 117 (see WP.29-158-09).

27. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2012/17 amending UN Regulation No. 117, introducing the possibility to use a test track according to the new ISO standard 10844:2011. The expert from ETRTO preferred to insert transitional provisions into the proposed amendments (GRRF-73-26). GRRF endorsed the amendments proposed by GRB (GRRF-73-17) and confirmed there was no conflict with on-going amendments under consideration at GRRF.

28. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2012/18 correcting the provisions of the temperature compensation in Regulation No. 117. GRRF noted that this proposal had been simultaneously transmitted to GRB who had made recommendations for submission to WP.29 and AC.1 for consideration at their March 2013 sessions as Supplement 03 to the 02 series of amendments to UN Regulation No. 117.
