24. The proposal received some comments. The expert from Spain recalled the work done on this matter by the informal group on UN Regulation No. 90. GRRF requested that an overview of the differences between this proposal and the outcome of the IWG in 2009. GRRF agreed to revisit this item on the basis of this document or a revised proposal submitted by the expert from Italy taking into account all the comments received.

25. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/2013/63 (Draft UN GTR on tyres), amended by ECE/TRANS/WP.29/GRRF/2014/20 (adopted at the seventy-seventh session of GRRF), and ECE/TRANS/WP.29/2013/122 (the corresponding technical report).

26. The expert from France presented GRRF-78-18 introducing minor updates to ECE/TRANS/WP.29/2013/63 and ECE/TRANS/WP.29/2013/122. He added that the timeline for further development of the gtr had to be updated, taking into account the delay to adopt phase I. GRRF adopted GRRF-78-18 as amended by GRRF-78-47 and as reproduced in Annex III to this report. GRRF requested the secretariat to submit the proposal to WP.29 and AC.3 for consideration at their November 2014 sessions.

27. GRRF reviewed the ECE/TRANS/WP.29/GRRF/2014/20 containing the amendments defined at the seventy-seventh GRRF session. The Chair recalled that GRRF previously agreed that updates to the UN GTR on tyres would be proposed after its establishment in the global registry by AC.3 to keep it in line with the latest regulatory developments.

28. Finally, the expert from France advised GRRF that his country would not be able to sponsor phase 2 of the UN GTR on tyres once phase 1 was concluded.

29. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2014/25 concerning snow tyres for use in severe snow conditions, specifically the items to be listed in the communication form of Annex 1 to UN Regulation No. 117.

30. The expert from ETRTO presented GRRF-78-13 proposing a corrigendum to Supplement 2 to 02 series of UN Regulation No. 117. The proposal noted that the Supplement to UN Regulation No. 117 introducing limits for C2 tyres in paragraph 6.4.1.1. had been adopted after the parallel proposal introducing those for C3 tyres. It highlighted an unintended consequence whereby the limits for C3 tyre had been deleted. Following the discussion, GRRF agreed that, while the consequence was an error, it was not appropriate to correct the regulation using corrigenda and agreed to consider the proposal as a Supplement.

31. GRRF adopted ECE/TRANS/WP.29/GRRF/2014/25 as reproduced in Annex IV to this report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions as draft Supplement 7 to 02 series of UN Regulation No. 117.

32. The expert from the Russian Federation, Vice-Chair of the Working Party on Noise (GRB), informed GRRF that a revised version of ECE/TRANS/WP.29/GRB/2014/7, including some minor editorial amendments, had been submitted by GRB to WP.29 and AC.1 for consideration at their March 2015 sessions.

33. GRRF agreed to defer consideration of ECE/TRANS/WP.29/GRRF/2014/26 and GRRF‑78‑12 to its February 2015 session.

34. The expert from ETRTO presented GRRF-78-42 supporting ECE/TRANS/WP.29/GRRF/2013/20 as amended by GRRF-76-06 as well as ECE/TRANS/WP.29/GRRF/2013/22 aimed at inserting All Terrain (AT) tyres in UN Regulation No. 75.

35. The expert from IMMA recalled GRRF‑76‑38 analysing the possible alternatives to type approve AT tyres, taking into account the technical requirements in UN Regulations Nos. 54, 75 and 106. He introduced ECE/TRANS/WP.29/GRRF/2014/24 proposing the insertion of AT tyres in UN Regulation No. 106 as an alternative to the ETRTO proposal above.

36. Following the discussion GRRF adopted ECE/TRANS/WP.29/GRRF/2013/22 and ECE/TRANS/WP.29/GRRF/2013/20 as amended by GRRF-76-06, GRRF-78-45 and GRRF‑78-46 and as reproduced in Annex V. The secretariat was requested to submit them to WP.29 and AC.1 for consideration at their March 2015 sessions as draft Supplement 12 to UN Regulation No. 106 and Supplement 15 to UN Regulation No. 75, respectively.

37. The expert from France presented GRRF-78-10 proposing to introduce a new annex on snow tyre for use in severe snow conditions in to UN Regulation No. 109. GRRF agreed to revisit the document at its February 2015 session and requested the secretariat to distribute GRRF-78-10 with an official symbol at that GRRF session.

38. The secretariat introduced GRRF-78-08 on ITS related activities conducted in 2014. He informed GRRF about the coming meetings of the IWG on ITS in Geneva on 11 November 2014 and the ITS round table in Brussels on 17 and 18 November 2014.

39. The expert from Japan presented GRRF-78-22 amending Annex 5 to the Consolidated Resolution on the Construction of Vehicles (R.E.3), to insert provisions for Remote Controlled Parking (RCP) systems. GRRF noted some comments and requested the secretariat to distribute GRRF-78-22 with an official symbol for consideration at the next GRRF session.

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.

42. The expert from Sweden presented GRRF-78-43, supporting GRRF-78-05 submitted by the LKAS small drafting group, introducing definitions and related LKAS requirements in to UN Regulation No. 79. The expert from OICA introduced GRRF-78-11 amending GRRF‑78‑05 and revising the warning requirements for the driver in the case that their attention to the task of steering could not be assured. GRRF agreed to resume discussion at its February 2015 session based on revised proposals.

43. The experts from Japan and Sweden presented GRRF-78-14 amending UN Regulation No. 79 aimed at (i) starting a discussion on the removal of the speed limitation for the Automatically Commanded Steering Function, (ii) introducing safety functions such as warnings and (iii) introducing On-Board Diagnostics (OBD) requirements permitting to verify the correct operational status of Electronic Systems assisting the steering. A number of GRRF experts considered some of those requirements to be design-restrictive. The Chair noted that the proposal was beyond the usual mandate of GRRF and he announced his intention to seek the guidance of WP.29 at its November 2014 session.

44. GRRF requested the secretariat to keep GRRF-78-14 as a reference document on the agenda, inform the IWG on ITS about this proposal and distribute GRRF-78-05 with an official symbol for consideration at the next GRRF session.

45. The secretariat 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 is expected to entry into force in March 2016. It was also noted that the GRRF actions related to IWVTA should ideally be completed in February 2015.

46. The GRRF Ambassador to IWTVA introduced GRRF-78-49 containing the highlights of the work progress of the IWVTA, the list of key documents and the calendar of meetings and actions.

47. The expert from OICA presented GRRF-78-28 amending ECE/TRANS/WP.29/GRRF/2014/13 on the tyre installation for M1 vehicles. The proposal received some comments. GRRF agreed to revisit this item at its next session on the basis of a revised proposal by OICA.

48. The expert from OICA announced that GRRF-76-13, GRRF-76-14, GRRF-76-18, GRRF-76-22 and GRRF-76-23 had been replaced by GRRF‑78‑19, GRRF‑78‑20 and GRRF‑78‑21.

49. The expert from OICA introduced the new documents as well as the proposals for separate UN 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 UN Regulation No. 13‑H (ECE/TRANS/WP.29/GRRF/2014/10). The Chair recalled the purpose of GRRF-76-33 and GRRF-76-34. OICA stated that GRRF-76-34 had been taken into account when drafting the proposals above. He introduced GRRF-78-29 proposing to delete the k-test method prescribed in Annex 7 and only keep the method prescribed in Appendix 2 to Annex 6 to align the UN Regulation with GTR No. 8. GRRF agreed to reconsider this proposal at its seventy-ninth session.

50. The expert from CLEPA introduced GRRF‑78‑41 proposing text addressing the specific question of how to deal with the original Annex 8 of UN Regulation No. 13‑H following splitting of the UN Regulation. The expert from OICA proposed some alternative wording (GRRF‑78‑50). GRRF agreed to reconsider at its February 2015 session the way to address the subject related to Annex 8.

51. GRRF agreed to resume consideration of this agenda item at its February 2015 session, based on three revised proposals by OICA and CLEPA.

52. The expert from OICA introduced GRRF-78-39 proposing a separate UN Regulation dedicated to Tyre Pressure Monitoring System (TPMS). He presented GRRF-78-48 proposing the corresponding amendments to Regulation No. 64, removing the provisions related to TPMS. He also presented GRRF-78-38, the corresponding consolidated version (based on UN Regulation No. 64 without the TPMS provisions). GRRF agreed to split UN Regulation No. 64 in two parts and to keep both proposals (GRRF-78-38 and GRRF‑78‑39) on the agenda of the seventy-ninth GRRF session.

53. The secretariat introduced GRRF-78-09, reporting on the highlights of the February 2014 session of ITC.

54. The expert from CLEPA introduced GRRF-78-31 on Advanced Driving Assist Systems (ADAS) and their levels of vehicle automation. He presented new technologies, such as Highway Autopilots and Valet Parking, which were under development and would require amendments to UN Regulations for vehicles to be type approved. GRRF welcomed this presentation. The Chair of GRRF encouraged all experts to continue sharing information on these types of innovations at the following GRRF session.

55. The secretariat introduced GRRF-78-15 reporting on the highlights of the 162nd (ECE/TRANS/WP.29/1108) and 163rd (ECE/TRANS/WP.29/1110) sessions of WP.29.

56. The secretariat introduced ECE/TRANS/WP.29/GRSG/2014/25 (initially proposed by the Working Party on Lighting and Light-Signalling (GRE)), as amended by GRRF‑78‑03 and introducing in to R.E.3, new categories of agricultural vehicles. The expert from the Russian Federation commented that the definitions proposed may create overlap especially when an agricultural vehicle could be classified as a Non Road Mobile Machinery (NRMM) and vice versa. The Chair of GRRF requested the experts to send their comments on this proposal to the secretariat.

57. Following the suggestion of the WP.29, the secretariat introduced GRRF-78-04 containing a list of definitions in the Regulations under the responsibility of GRRF. The Chair of GRRF recalled GRRF‑76‑03 and noted that no follow-up action was defined. The secretariat announced that it was looking for a central and suitable location on the website to collect this useful information.

58. Learning that Mr. Masashi Ishihara (Japan) and Mr. Jürgen Bräuninger (CLEPA) would retire and, therefore, no longer attend the sessions, GRRF acknowledged their considerable contributions to the activities of the group. GRRF wished them long and happy retirements.

59. The expert from CLEPA introduced GRRF-78-51 on difficulties linked to the definition of “variant” of brake disc/drum in UN Regulation No. 90. The expert informed that a proposal to UN Regulation No. 90 would be submitted to GRRF for consideration at its next session.

60. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and Amends. 1 and 2), GRRF called for the election of officers on Tuesday afternoon. Mr. B. Frost (United Kingdom) was unanimously elected Chair of GRRF for the sessions scheduled for the year 2015. Mr. H. Kubota (Japan) was elected Vice-Chair of GRRF for the same period.

29. The expert from CLEPA introduced GRRF-80-12 proposing amendments to provisions defined for equivalent brake discs and drums and a relaxation of the requirement on the thickness variation for interchangeable replacement discs or drums. The expert from OICA expressed some concerns. The experts from OICA and CLEPA agreed review the proposal together. GRRF requested the secretariat to distribute the proposal with an official symbol for its February 2016 session.

30. The Chair of GRRF recalled the establishment of GTR No. 16 (Tyres) in the Global Registry, the authorization to develop an amendment to GTR No. 16 (see ECE/TRANS/WP29/AC.3/42) and the sponsorship of the Russian Federation for this activity. The expert from ETRTO reported (GRRF-80-04, GRRF-80-05) and presented the status of the work done by the group of interested experts dealing with this amendment (GRRF-80-20, GRRF-80-21 and GRRF-80-22). GRRF explored the possible wording to be used to allow Contracting Parties to transpose at their wish some of the optional tests in the GTRs and therefore reviewed the precedent case of GTR No. 7. GRRF experts agreed to send written comments to the group of interested experts and to have a webex meeting in October, so that a formal proposal can be submitted for consideration at the February 2016 session of GRRF.

31. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2015/23 proposing to amend tyre dimensional requirements in Regulation No. 30. GRRF adopted the proposal with the following correction:

41. The expert from France introduced GRRF-80-17 proposing provisions for tyres designed for a “special” application that also fulfil the definition of a “snow” tyre. GRRF requested the secretariat to distribute this document with an official symbol at the next session of GRRF.

42. The expert from ETRTO presented ECE/TRANS/WP.29/GRRF/2015/30 proposing to amend the tyre dimensional requirements in Regulation No. 75. GRRF adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 16 to Regulation No. 75.

43. The expert from ETRTO presented ECE/TRANS/WP.29/GRRF/2015/31 proposing amendments related to Improved Flexion (IF) tyres and Very high Flexion (VF) tyres avoiding possible misunderstanding for the application of the EC Regulation No. 167/2013 that refers to Regulation No. 106. GRRF adopted this proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as Supplement 13 to Regulation No. 106.

44. The expert from the Slovak Republic introduced ECE/TRANS/WP.29/GRRF/2015/39 as amended by GRRF-80-16 proposing clarifications for Regulation No. 109. The expert from ETRTO recalled that the proposed clarifications would also be relevant for Regulations Nos. 30 and 54. GRRF agreed to resume consideration of these clarifications on the basis of a revised proposal that the experts from ETRTO and the Slovak Republic volunteered to prepare for the September 2016 session of GRRF.

45. The expert from France introduced ECE/TRANS/WP.29/GRRF/2015/32 together with the corresponding document relevant for Regulation No. 30 (see para. 34 above).

46. GRRF did not receive any other document to be discussed under this agenda item.

47. The Chair of GRRF presented the guidance document on automated driving proposed by the IWG on ITS/AD and endorsed by WP.29 at its June 2015 session. GRRF agreed to refer this document to the IWG on ACSF.

48. The expert from OICA invited the experts of GRRF to witness a demonstration of a vehicle equipped with an RCP system, with the driver being out of his car during the parking manoeuvre and controlling the car’s motion via a smartphone or a smart key. The experts were presented a well-functioning vehicle equipped with various sensors ensuring safety redundancies. A day before on 16 September 2015, the Ministers of Transport of the G7 Countries witnessed a similar demonstration at their meeting at the Frankfurt Motor Show. In their declaration, the transport ministers of the G7 States and the European Commissioner for Transport stressed that “A key prerequisite for the widespread deployment of innovative and reliable technologies in road transport is that modern vehicle systems are legally permissible and suitable for mass production. Revising, as appropriate, regulations applicable in the G7 states, and those established under the agreements administered by the UN World Forum for the Harmonization of Vehicle Regulations (WP.29) – is of crucial importance.”

49. The expert from OICA introduced GRRF-80-18 (i) presenting the system and those Regulations relevant for this system, (ii) concluding that RCP could be type-approved according to Regulations Nos. 79 and 13-H and (iii) in line with the requirements of the 1968 Vienna Convention on road traffic. The expert of GRRF expressed positive comments about the systems and agreed that clarifications should be added in the relevant Regulations to capture the benefits of such systems without compromising safety. The chair recalled that even though correctly type-approved, such system would still be subject to regulations related to the use of road vehicles. He added that the concern related to cyber security should be addressed.

50. The Chair of GRRF recalled various cases of cyber-attacks (“hacking”) disclosed in specialized media which were not only affecting automated driving vehicles but also conventional vehicles. The expert from the Russian Federation agreed that this subject should be reported to WP.29. He recalled that the Working Party on General Safety (GRSG) already manage regulations on the protection of vehicle against unauthorized use (UN Regulations Nos. 18 and 116). The expert from Japan also agreed that WP.29 should tackle this issue. He added that both the IWGs on ACSF and ITS/AD would have to tackle this issue within their current mandates. He mentioned that special attention would be needed for connected vehicles and especially those allowing “over the air” (OTA) updates. The expert from Germany stated that “eSecurity” is a serious issue and agreed that WP.29 should tackle this matter.

51. Referring to GRRF-78-27, the expert from CLEPA, on behalf of CLEPA and OICA, introduced ECE/TRANS/WP.29/GRRF/2015/37 proposing to align the requirements to be met in case of the steering system and the braking system of a vehicle share the same energy source with those of Regulations Nos. 13 and 13-H. GRRF adopted the proposal as reproduced below:

Insert a new paragraph 5.3.1.6., to read:

52. The Secretary of GRSG introduced ECE/TRANS/WP.29/GRSG/2015/12, proposing amendments to Regulation No. 79 related to the recent adoption of a Supplement to Regulation No. 43 introducing Camera-Monitoring-Systems. GRRF adopted the proposal.

53. GRRF requested the secretariat to submit both adopted proposals 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.

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

55. The Chair of GRRF recalled the activities done by the IWG on ACSF and proposed to postpone the discussion on LKAS (ECE/TRANS/WP.29/GRRF/2015/2 and GRRF-79-04) to make sure that the findings of the informal group could be reflected when working the technical provisions for LKAS. The expert from France agreed to present GRRF-80-08 at the February 2016 session of GRRF. GRRF agreed to resume consideration of this item at its nest session.

56. The Chair of GRRF recalled that the draft Terms of Reference (ToR) for the IWG on ACSF were endorsed by GRRF and WP.29 but subject to minor amendments. The expert from Germany on behalf of Germany and Japan presented GRRF-80-03 proposing a revised version of the ToR. GRRF adopted the revised terms of reference as reproduced in Annex V to the session report.

57. The expert from Germany, on behalf of the Co-Chairs of the IWG on ACSF introduced GRRF-80-38 presenting the status of the work done of the IWG on ACSF. The IWG is proposing five categories of ACSF independently of any automation levels definitions as well as testing procedures for the proper assessment of the safety performance of these functions. GRRF endorsed the status report and agreed to resume consideration of this agenda item at its next session.

58. The GRRF Ambassador presented GRRF-80-42 reporting on the activities of the IWG on IWVTA and its subgroups. GRRF noted the progress done by the IWG. GRRF also noted that the pre-testing task force would test procedures related to Regulation No. 0 and that GRRF actions related to IWVTA should ideally be completed by February 2016.

59. In absence of new proposals tabled by the expert from OICA, the Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2014/13 amended by GRRF-79-08 proposing a draft Regulation on tyre installation and that the expert from OICA agreed to table a revised proposal addressing the comments received. The expert from Japan tabled GRRF-80-26 addressing concerns expressed at the seventy-ninth session of GRRF. The expert from EC kindly informed GRRF that the lack of harmonization between the draft UN Regulation and the existing EC Regulation 458/2011 might prevent the EU from applying this regulation. The expert from OICA submitted GRRF-80-36 at the end of the session for review and comments by the experts of GRRF in view of the submission of an official document for the February 2016 session of GRRF.

60. The expert from the UK recalled, on behalf of the group of interested experts dealing with this matter, the purpose of 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). She then introduced ECE/TRANS/WP.29/ GRRF/2015/33 as amended by GRRF-80-32 proposing transitional provisions 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. GRRF agreed to reconsider this proposal at its February 2016 session.

61. The recalled the purpose of 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 from Regulation No. 64 the provisions related to TPMS. No document was submitted before the start of the session. The expert from OICA submitted at the end of the session GRRF-80-34 and GRRF-80-35 for review and comments by the experts of GRRF in view of the submission of an official document for the February 2016 session of GRRF.

62. GRRF did not receive any new document to be discussed under this agenda item.

63. GRRF did not receive any document to be discussed under this agenda item.

64. In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and Amends. 1 and 2), GRRF called for the election of officers on Tuesday afternoon. Mr. Frost (United Kingdom) was unanimously elected Chair of GRRF for the sessions scheduled for the year 2016. Mr. Murai (Japan) was elected Vice-Chair of GRRF for the same period.

65. The secretariat introduced GRRF-80-14 reporting on the highlights of the 165th and 166th sessions of WP.29 relevant for GRRF. For more information, please refer to the session reports.

66. The secretariat reported that GRSP was using the abbreviation “VSF” as “Vehicle Seat Fixture” and proposed to stop using “VSF” as “vehicle stability function”. GRRF didn’t support this idea as “VSF” was not only used as an abbreviation but also VSF is part of an approval mark for certain vehicles type-approved according to Regulation No. 13.

67. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2015/44 proposing to extend the possibility of actuating the service braking system as described in Regulation No. 89 to vehicles of categories M2 and N2 below 5t. Some experts expressed concerns related to the risk of “hot brakes” phenomena when the (adjustable) speed limitation device would function down hills. The expert from OICA agreed to provide more information about the proposal to be presented at the February 2016 session of GRRF. GRRF agreed to resume consideration on this item at its February 2016 session and requested the secretariat to dedicate an agenda item to Regulation No. 89.

68. The expert from IMMA introduced GRRF-80-33 proposing to allow the optional fitment of Emergency Stopping Signals for motorcycles. GRRF welcomed the idea and agreed to resume consideration of this proposal at its February 2016 session.

69. Learning that Mr. Masahito Yamashita (JASIC) would no longer attend the sessions, GRRF acknowledged his great cooperation with GRRF and wished him all the best for his new responsibilities.

70. Learning that Mr. Georges Dimitri (ETRTO) would retire and, therefore, no longer attend the sessions, GRRF acknowledged their considerable contributions to the activities of the group. GRRF wished them long and happy retirements.
