Working Party on Brakes and Running Gear | Session 79 | 16-20 Feb 2015

1. The Working Party on Brakes and Running Gear (GRRF) held its seventy-ninth session from 16 to 20 February 2015 in Geneva. The meeting was chaired by Mr. B. Frost (United Kingdom). Experts from the following countries participated in the work, following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, ECE/TRANS/WP.29/690/Amend.1 and Amend. 2): Australia, Belgium, Canada, China, Czech Republic, Denmark, Finland, France, Germany, Hungary, India, Italy, Japan, the Netherlands, Norway, Kuwait, Qatar, Russian Federation, Saudi Arabia, Spain, Sweden, Switzerland and the United Kingdom of Great Britain and Northern Ireland (UK). An expert from the European Commission (EC) also participated. Experts from the following non-governmental organizations (NGOs) participated: the European Association of Automotive Suppliers (CLEPA), the European Tyre and Rim Technical Organisation (ETRTO), the International Motorcycle Manufacturers Association (IMMA), the International Organization for Standardization (ISO), the International Organization of Motor Vehicle Manufacturers (OICA) and Rubber Manufacturers Association (RMA). Upon the special invitation of the Chair, the following NGOs participated: Bureau International Permanent des Associations de Vendeurs et Réchappeurs de Pneu (BIPAVER), the European manufacturers association of materials handling, lifting and storage equipment “Fédération Européenne de la Manutention” (FEM) Imported Tyre Manufacturers Association (ITMA), and the Verband der Automobilindustrie (VDA).

2. The Director of the UNECE Transport Division, Ms. E. Molnar, introduced to the delegates Mr. W. Nissler, Chief of the Vehicle Regulations and Transport Innovations Section. She announced that the next Inland Transport Committee (ITC) was scheduled to be held on 26-24 February 2015 and invited the delegates to participate. She concluded her statement by reporting on the latest UNECE Publication on sustainable development.

3. GRRF considered and adopted the agenda prepared for the seventy-ninth session (ECE/TRANS/WP.29/GRRF/2015/1 and Add.1) as updated and reproduced in GRRF-79-26, including all informal documents received until the session’s starting date.

4. GRRF also adopted the running order for the session as proposed in GRRF-79-01. The informal documents distributed during the session are listed in Annex I of the session report.

5. The secretariat introduced GRRF-79-25, announcing that the next GRRF session would take place on 15-18 September 2015 and recalling that the deadline for the submission of official documents would be 18 June 2015. These dates may be reconfirmed by the secretariat.

6. The expert from OICA, recalling its presentation at the seventy-eighth session of GRRF and the proposed alternatives proposed e.g. in GRRF-78-30 to explore possibilities of exemption for specific vehicle applications (e.g. off-road vehicles), sought for guidance on how to proceed. He explained that with the given texts of Regulations No. 130 and 131, vehicles not benefiting from Advanced Emergency Braking Systems (AEBS) or Lane Departure Warning Systems (LDWS) get individual single approvals, which is costly and time consuming. The expert from FEM explained that in their views mobile cranes vehicles should not be equipped with AEBS or LDWS.

7. GRRF preferred the proposed option to amend the introduction of Regulations Nos. 130 and 131, providing useful information to Contracting Parties applying these Regulations.

8. As no documents presented for technical change but only to discuss the splitting of the regulation, GRRF discussed this item in conjunction with item 10c. (see para. 45).

9. The Chair of the informal working group (IWG) on MVC reported on the activities of the group’s recent meetings in Gothenburg and Paris. He announced that the group was reviewing the coupling, braking, stability and steering aspects of MCV as well as on a definition of a Dolly. He sought guidance on the latter, whether this should be added to the R.E.3. or in a Regulation. He also sought guidance on whether the group should address articulated drawbars.

10. GRRF endorsed the status report. GRRF agreed that dollies should be dealt with as a vehicle and that the group should first address rigid drawbars and then, at a later stage, articulated drawbars.

11. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/GRRF/2013/13, adopted during the seventy-fifth GRRF session. The document remained on the agenda of GRRF, pending submission to WP.29 and AC.1 of the adopted text for Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment), 89 (Speed limitation devices), 130 (LDWS) and 131 (AEBS).

17. The Secretary of the IWG on Regulation No. 55. introduced GRRF-79-03 presenting the proposal to restructure the Regulation, separating performance requirements from the application requirements to be included in a new annex. GRRF supported this idea. The Secretary of the group informed that a draft outline was proposed in the working paper R55-08-05.

18. The Chair of the IWG on Regulation No. 55 introduced ECE/TRANS/WP.29/GRRF/2015/14, partially addressing the mandate defined in the terms of reference to the group. He announced that further work would be necessary to deliver the remaining items expected. The Chair of GRRF agreed to inform WP.29 about the necessity to extend the mandate duration of the group. The proposal received some comments. The Chair of the IWG volunteered to prepare a revised proposal for the September 2015 session of GRRF.

20. The expert from EC introduced GRRF-79-16, proposing to apply to tricycles the existing Anti-lock Braking Systems (ABS) requirements for Powered Two Wheelers (PTWs). The proposal was accepted in principle as it proposed a harmonization with the corresponding EU directive. As the proposed wording would also affect other L-category vehicles, the expert from EC volunteered to prepare a revised proposal for the September 2015 session of GRRF.

19. The expert from IMMA presented GRRF-79-16, proposing Electromagnetic Compatibility (EMC) requirements to be introduced in Regulation No. 78. The proposal received some comments.

33. The expert from ETRTO introduced GRRF-79-32, proposing amendments on the variation of load capacity with speed in Annex 7 to Regulation No. 106. GRRF requested the secretariat to distribute this document at its September 2015 session with an official symbol.

34. The expert from France presented ECE/TRANS/WP.29/GRRF/2015/3, amended by GRRF-78-10 and GRRF-79-28, introducing provisions for the type approval of retreaded snow tyres for use in severe snow conditions. The expert from Hungary introduced GRRF 79 27, providing some comments. GRRF adopted the proposal as amended (GRRF-79-28 and GRRF-79-34) by Annex III and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2015 sessions as draft Supplement 7 to Regulation No. 109.

35. The expert from the European Commission presented GRRF-79-35, informing the experts of GRRF about a study on safety-related aspects of tyre use.

36. The expert from Japan recalled the purpose of GRRF-78-14, presented at the seventy-eighth session of GRRF, proposing the deletion, in some circumstances, of the 10 km/h speed limit for systems operating an Automated Controlled Steering Function. The Chair of GRRF proposed to further discuss this item together with item 9(b) below.

39. The Chair of GRRF informed GRRF about the discussion held on ITS during the November 2014 session of WP.29. WP.29, for permitting GRRF to make progress at its seventy-ninth session, agreed that the IWG on ITS/Automated Driving (AD) would directly provide guidance to GRRF. This guidance is reproduced in GRRF-79-31. GRRF agreed to work during this session within the framework proposed by the IWG on ITS/AD and to consider regulating technologies remaining in the primary control of the driver at all time

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.

41. The expert from Sweden introduced ECE/TRANS/WP.29/GRRF/2015/2 as amended by GRRF-79-04, submitted by the LKAS small drafting group and introducing definitions and related LKAS requirements in to Regulation No. 79. The proposal received some comments. The expert from Japan introduced GRRF-79-29 in conjunction with item 12(b) below. GRRF agreed to resume discussion at its September 2015 session based on revised proposals.

42. The expert from Germany introduced GRRF-79-23 proposing Terms of Reference (ToR) for a IWG on Automated Controlled Steering Functions (ACSF). GRRF agreed with the proposed terms of reference as reproduced in Annex IV. GRRF also agreed that the IWG would submit a revision of the ToR at the next GRRF session in September 2015. The Chair informed that he would present the draft ToR to WP 29 in June 2015 but requested that at their first meeting the informal group should refine the ToR in line with comments received. The Chair also suggested that the timing suggested was very ambitious and recommended to the group that the plan of work should be extended to a more realistic date.

43. The GRSG Ambassador, on behalf of the GRRF Ambassador, presented GRRF-79-37 and reported on the activities of the IWG on IWVTA and its subgroups. GRRF noted that IWVTA was one of the main objectives associated with Revision 3 of the 1958 Agreement which was expected to enter into force in March 2016 if no adoption delay would occur. He recalled that the GRRF actions related to IWVTA should ideally be completed by February 2015.

44. The expert from OICA presented GRRF-79-08, superseding ECE/TRANS/WP.29/GRRF/2014/13 on the tyre installation for M1 vehicles. The proposal received some editorial comments. GRRF agreed to revisit this item at its September 2015 session on the basis of a revised proposal by OICA.

45. The expert from OICA introduced GRRF-79-05, GRRF-79-06 and GRRF 79 07 superseding official proposals for separate Regulations on Brake Assist Systems (BAS) (ECE/TRANS/WP.29/GRRF/2014/11) and on Electronic Stability Control (ESC) (ECE/TRANS/WP.29/GRRF/2014/12) extracted from Regulation No. 13 H (ECE/TRANS/WP.29/GRRF/2014/10). GRRF agreed that further work e.g. on the transitional provisions, was necessary to make sure that Countries mandating the fitment of ESC or BAS on the basis of the existing text of Regulation No. 13-H would be able to continue to mandate this fitment, unaffected by this extraction. The expert from UK agreed to lead an ad-hoc group of interested members on addressing the transitional provisions, to establish a methodology for all of the regulations that would need to be separated for IWVTA. GRRF agreed to reconsider this proposal at its September 2015 session.

46. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2015/12 as amended by GRRF-79-09 and ECE/TRANS/WP.29/GRRF/2015/13 as amended by GRRF-79-10 proposing a separate Regulation dedicated to Tyre Pressure Monitoring System (TPMS) and removing the provisions related to TPMS of Regulation No. 64. The expert from the Russian Federation presented GRRF-79-20-Rev.1 containing an alternative proposal for the drafted transitional provisions in GRRF-79-09. GRRF agreed to revisit this item at its September 2015 session on the basis of a revised proposal.

47. The expert from Japan introduced GRRF-79-14, presenting the modification that his country was implementing in its national legislation, introducing provisions mandating the fitment of advanced safety systems.

48. The secretariat introduced GRRF-79-25 reporting on the highlights of the 164th session of WP.29 relevant for GRRF. For more information, please refer to the session report ECE/TRANS/WP.29/1112.

49. The secretariat recalled the purpose of ECE/TRANS/WP.29/2015/35, proposed by the Working Party on Lighting and Light-Signalling (GRE), introducing new categories of agricultural vehicles.

50. The expert from Japan introduced GRRF-79-29, presenting the proposals on LKAS discussed under item 9(b) as well as GRRF-79-15 tabled by the expert from Japan and Germany, superseding ECE/TRANS/WP.29/GRRF/2015/4 and proposing amendments to Annex 5 to the Consolidated Resolution on the Construction of Vehicles (R.E.3) inserting provisions for Remote Controlled Parking (RCP) systems. Noting that traffic rules in some countries would require the driver being seated in the car during its motion, and also noting the preference of GRRF to not amend R.E.3 for this purpose, GRRF advised the authors of the proposal to consider a new Regulation for RCP. GRRF agreed to resume consideration on this item at its September 2015 session.

51. The secretariat recalled the ongoing discussion on definitions, acronyms, abbreviations and symbols used in regulations. The secretariat announced that the relevant documents (based on GRRF-76-03 and GRRF-78-04) were added to the definitions page on the WP.29 website.

52. GRRF did not receive any new proposal to be discussed under this agenda item.

Working Party on Noise | Session 62 | 1-3 Sep 2015

1. The Working Party on Noise (GRB) held its sixty-second session from 1 to 3 September 2015 in Geneva. The meeting was chaired by Mr. S. Ficheux (France). Experts from the following countries participated in the work following Rule 1(a) of the Rules of Procedure of the World Forum for Harmonization of Vehicle Regulations (WP.29) (TRANS/WP.29/690, Amend. 1 and Amend. 2): Austria; Belgium; China; France; Germany; Hungary; India; Italy; Japan; Netherlands; Norway; Poland; Russian Federation; Spain; Sweden; Switzerland; United Kingdom of Great Britain and Northern Ireland and the United States of America. An expert from the European Commission (EC) participated. Experts from the following non-governmental organizations also participated: International Council of Academies of Engineering and Technological Sciences, Inc. (CAETS); European Tyre and Rim Technical Organisation (ETRTO); International Motorcycle Manufacturers Association (IMMA); International Organization for Standardization (ISO); International Organization of Motor Vehicle Manufacturers (OICA) and World Blind Union (WBU).

2. GRB considered and adopted the agenda.

3. The expert from the Russian Federation introduced an updated text of Regulation No. 28, with the aim to align its provisions with the current rulemaking practice. (ECE/TRANS/WP.29/GRB/2015/7). This proposal received comments from the experts of France, India and OICA (GRB-62-20, GRB-62-18 and GRB-62-21-Rev.1, respectively). In particular, the expert from France proposed to include a modular approach to permit the introduction of other audible signals. GRB invited the expert from the Russian Federation to take these comments into account and to submit a revised document for consideration at the next session.

4. The expert from IMMA proposed to amend paragraph 8.2. of Regulation No. 41 on the conformity of production (ECE/TRANS/WP.29/GRB/2015/8), thus formalizing the interpretation agreed upon at the fifty-sixth session of GRB (ECE/TRANS/WP.29/GRB/54, para. 5). GRB adopted this proposal and requested the secretariat to submit it to the World Forum for Harmonization of Vehicle Regulations (WP.29) and the Administrative Committee (AC.1) for consideration and vote at their March 2016 sessions as a draft Supplement 4 to the 04 series of amendments to Regulation No. 41.

5. The expert from IMMA proposed to correct minor reference errors in Supplement 2 to the 04 series of amendments to Regulation No. 41 (GRB-62-05). GRB adopted this proposal, as contained in Annex II, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions.

6. The expert from IMMA also proposed to extend, until 1 January 2018, the 1 dB(A) allowance for motorcycles tested in the second gear (GRB-62-15). Taking into account interventions of the experts from Germany and EC, GRB did not support this proposal.

7. GRB noted that WP.29 and AC.1, at their June 2015 sessions, had adopted the consolidated proposal for the 03 series of amendments to Regulation No. 51 (ECE/TRANS/WP.29/2015/62).

8. The expert from OICA proposed to clarify the wording of Annex 3, paragraph 3.1.3. (GRB-62-19-Rev.1). GRB adopted this proposal, as contained in Annex III, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions as a draft Supplement 1 to the 03 series of amendments to Regulation No.51.

9. No new information was reported under this item.

10. No proposals were considered under this item.

11. No new information was reported under this agenda item.

12. The expert from the Netherlands presented a study (GRB-62-09 and Add.1) on noise emission from the Original Equipment Manufacturer (OEM) tyres of a specific size which were found to be around 1 dB(A) lower than the one from replacement tyres of the same size. The expert, thus, proposed to further reduce the limit values for OEM tyres in the 02 series of amendments to Regulation No. 117 (GRB-62-11 and Add.1).

13. The expert from Switzerland expressed his support for the general direction of the Dutch proposal. The experts from Germany and EC were of the view that, at this stage, it would be premature to tighten the tyre noise limits of Regulation No. 117. The expert from France called for a holistic approach to this issue. The experts from ETRTO and OICA expressed doubts about the representativeness of the tyre sample used in the Dutch study. The expert from ETRTO also delivered comments on the proposal for amendments to Regulation No. 117 (GRB-62-17). Finally, GRB invited all experts to further study the Dutch proposal and decided to revert to this issue at the next session.

14. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2015/27 and ECE/TRANS/WP.29/GRRF/2015/32 which would be considered at the forthcoming session of the Working Party on Brakes and Running Gear (GRRF) (15-18 September 2015). GRB experts were invited to review these documents and to provide their colleagues in GRRF with comments, if any.

15. The expert from IMMA proposed collective amendments to Regulations Nos. 9, 41, 63 and 92 to clarify that the provisions on fibrous materials are only applicable if such materials are in contact with exhaust gases (GRB-62-06-Rev.1). Following comments by the experts from Germany and OICA, GRB invited IMMA to revise the proposal and re-submit it to the next session, possibly as an official document.

16. The expert from China briefed GRB on the activities of the China vehicle noise standards working group (GRB-62-10). The experts from Japan informed GRB about the trends of noise regulation in Japan and gave an overview of the future policy for motor vehicle noise reduction (GRB-62-13-Rev.1 and GRB-62-12, respectively). The expert of ISO reported on the activities of his organization on interior noise, with the aim to review ISO 5128 (GRB-62-07). GRB took note of these presentations and felt that some of the issues raised could be included in the programme of work of GRB (see para. 27 below).

17. The expert from the Netherlands presented a policy indicator for road traffic noise emissions (GRB-62-14 and Add.1) that determines the effect of noise control at source on average noise levels at the dwelling facade and on estimated numbers of annoyed and sleep disturbed people. According to the expert, the indicator had been calculated for the Netherlands, showing a potential reduction of up to 50 per cent in annoyed and sleep disturbed people, if tighter limits for vehicles and tyres were introduced and road surfaces were improved. He also suggested that the policy indicator be applied for the whole EU. The experts from ETRTO and OICA commented on the proposed concept. The Chair proposed to continue the discussion in the future, taking into account comments from the industry.

18. The expert from the Netherlands briefed GRB on the Dutch public campaign “Choose the Best Tyre” and on potential benefits of energy-efficient tyres and correct tyre pressure maintenance (GRB-62-01 and Add.1, GRB-62-02-Rev.1). The Chair recalled other Dutch studies on this topic and commended the experts from the Netherlands for the considerable work undertaken and interesting results. He also called for a holistic approach and closer cooperation between the governments and industry in this area.

19. The expert from the Belgian Road Research Centre (BRCC) presented a new solution for noise reducing pavements, namely the poro-elastic road surface which provides for extreme noise reduction in a range from 7 to 12 dB(A) (GRB-62-23). GRB thanked BRCC for this presentation and looked forward to further studies and presentations on the issue.

20. The experts from France and Germany, in their capacity of Co-chairs of the Informal Working Group (IWG) on a Quiet Road Transport Vehicles (QRTV) Regulation under 1958 Agreement, presented a draft QRTV Regulation (ECE/TRANS/WP.29/GRB/2015/9 and GRB-62-22).

21. The expert from WBU called for shared responsibility of drivers and vulnerable road users for road safety and requested that the Audible Vehicle Alert System (AVAS) of QRTV be “ON” while the vehicle is stationary and that the driver should not be able to deactivate (or pause) AVAS (GRB-62-03). He also referred to a study (GRB-62-16) suggesting that the proposed AVAS level of sound did not seem to make QRTV with AVAS more detectable to the average blind person than was QRTV without AVAS. According to the study, more research would be needed to determine a minimal noise level that would satisfy the desire to reduce noise emissions while remaining safe for pedestrians.

22. GRB recalled that AVAS provisions had been recently adopted in the European Union and were scheduled to be announced in the United States of America in November 2015. Therefore, GRB stressed the urgent need for a QRTV Regulation and decided to adopt ECE/TRANS/WP.29/GRB/2015/9, subject to minor editorial corrections. The secretariat was requested to submit it to WP.29 and AC.1 for consideration and vote at their March 2016 sessions. At the same time, GRB was of the view that the concerns raised by WBU should be studied further, also bearing in mind recent technologies that improve road safety. To address these issues, GRB agreed that the mandates of both IWG QRTV for a Regulation and IWG QRTV for a GTR should be extended and requested the Chair to seek the WP.29 consent.

23. GRB noted that WP.29, at its March 2015 session, had considered a list of acronyms and abbreviations used in Regulations (WP.29-165-17) and noted that the acronym RESS “Replacement Exhaust Silencing System” is used in Regulation No. 92. However, RESS is widely used as “Rechargeable Energy Storage System”, for example, in Regulations Nos. 10, 12, 94, 95 and 100. For this reason, WP.29 had requested GRB to introduce, in the medium term, an alternative acronym for “Replacement Exhaust Silencing System” in Regulation No. 92 (WP.29-165-16). GRB invited experts and, in particular, IMMA to study this issue and decided to revert to it at the next session.

24. No proposals were introduced under this item.

25. The secretariat informed GRB about the recent activities of the Subgroup on UN Regulation No. 0, in particular, about its proposal to introduce a new concept of “IWVTA vehicle type” which would group vehicles of a given type and with the same level of conformity.

26. The secretariat reported on the highlights of the 165th and 166th sessions of WP.29 (ECE/TRANS/WP.29/1114, ECE/TRANS/WP.29/1116, GRB-62-04).

27. The Chair presented a list of possible issues for the future GRB activities prepared at an informal meeting convened by the Chair in July 2015 (GRB-62-08). Various experts expressed their interest in pursuing specific items on the list and/or proposed new subjects. To take these comments into account and to prepare an updated and prioritized list, the Chair informed GRB about his intention to convene a second meeting of stakeholders at the beginning of December 2015, the results of which would be reported to the next session of GRB.

28. GRB was informed that Mr. Georges Dimitri (ETRTO) would retire and no longer attend its sessions. GRB thanked him for his contributions and wished him a happy retirement.

29. GRB took note that Mr. Masahito Yamashita (Japan) would no longer attend its sessions. GRB thanked him for his contributions and wished him success in his future career.

30. For its sixty-third session, scheduled to be held in Geneva from 16 (starting at 2.30 p.m.) to 18 (concluding at 5.30 p.m.) February 2016, GRB noted that the deadline for the submission of official documents to the secretariat would be 23 November 2015, twelve weeks prior to the session. The following provisional agenda was adopted:
1. Adoption of the agenda.
