The expert from the Russian Federation presented GRB-59-02 proposing a tyre rolling resistance test results evaluation using a mathematical algorithm, to be added as an alternative to the existing one in the text of the Regulation. He also presented the results of a validation study of the proposed algorithm for tyres of the C1 category performed in France, in cooperation with the Russian Federation (GRB-59-07 and GRB-59-08). GRRF noted that this proposal may be submitted by GRB to WP.29 as a supplement to UN Regulation No. 117. GRRF recommended further steps for a better understanding of the proposed method’s sensitivity, suggesting: (i) extending the validation study for tyres of categories C2 and C3 and (ii) verifying the application of the proposed alternative in the conditions of the conformity of production. The GRRF Chair invited the experts to provide their comments on the proposal to the GRB secretariat with a copy to the expert from the Russian Federation.

25. The expert from ETRTO presented GRRF-76-25, supporting ECE/TRANS/WP.29/GRRF/2013/20 amended by GRRF-76-06 as well as ECE/TRANS/WP.29/GRRF/2013/22 [concerning UN R106] and proposing the insertion of All Terrain Vehicle (ATV) tyres in UN Regulation No. 75.

26. In response to the proposal above, the expert from IMMA presented GRRF-76-41 supporting the insertion of provisions for ATV tyres in UN Regulation No. 106. GRRF agreed to revisit this subject at it September 2014 session on the basis of a revised proposal that the experts from IMMA and ETRTO agreed to prepare.

27. The expert from ETRTO introduced ECE/TRANS/WP.29/GRRF/2014/2 as amended by GRRF-76-41, inserting a new marking and, under “categories of use”, a definition for construction application (Industrial tractor) tyres. GRRF adopted this proposal as amended by Annex V of the session report and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2014 sessions as a part of the draft Supplement 11 to Regulation No. 106.

28. The expert from ETRTO also introduced ECE/TRANS/WP.29/GRRF/2014/15 clarifying the marking requirements in Regulation No. 106.

The documents presented two sets of proposals amending the introduction and scope of UN Regulations Nos. 130 and 131 exploring possibilities of exemption for specific vehicle applications (e.g. off-road vehicles).

6. Several Contracting Parties (CPs) expressed extensive concerns on these proposals. The expert from OICA expressed his intention to develop other options for consideration at the seventy-ninth GRRF session.

7. GRRF discussed this item in conjunction with item 10(c) (see para. 49).

8. The Chair of the informal working group (IWG) on ACV introduced GRRF‑78‑17 reporting on the outcome of the group’s recent meetings, recalling the completion of the work on ACV and proposing to focus on Modular Vehicle Combinations (MVC).

9. GRRF noted the proposed updated Terms of Reference of the IWG (GRRF‑78‑16), converting its denomination to MVC and expanding its mandate. Following the concerns expressed by the expert from Germany on potential work conflict and/or overlap between the IWG on Regulation No. 55 and the IWG on MVC, GRRF agreed to monitor both informal groups’ progress to avoid such redundancy. Finally, GRRF adopted GRRF‑78‑16 as reproduced in Annex II of the GRRF-78 report.

10. 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 UN Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new UN Regulations on Lane Keeping Assist System (LKAS) and Parking Assist System (PAS).

11. The expert from IMMA presented GRRF-78-52 addressing GRRF concerns about the absence of Electromagnetic Compatibility (EMC) requirements in to UN Regulation No. 78. GRRF agreed to resume consideration of this matter at its February 2015 session awaiting a presentation by IMMA on the difficulties at referring to the EMC requirements of UN Regulation No. 10 for vehicles of L-category.

12. The expert from Germany introduced GRRF-78-40 based on ECE/TRANS/WP.29/GRRF/2013/29 which detailed proposed amendments to UN Regulation No. 13 on provisions for electro-mechanical braking systems. GRRF acknowledged the status report. The experts from Germany and the Netherlands volunteered to prepare a revised proposal for consideration at the February 2015 session, addressing the remaining open issues.

13. The expert from Germany questioned the decision of GRRF taken in 2004 to exclude the use of the overrun brake for a full trailer (TRANS/WP.29/GRRF/2004/11) and not extended to electrical brakes according to Annex 14. The expert from the Netherlands noted that the conscious decision in 2004 to exclude overrun brakes for full trailers was design restrictive. He suggested that the corresponding provisions should be replaced by performance requirements.

14. The expert from OICA announced that ECE/TRANS/WP.29/GRSG/2014/12 and GRSG‑106‑35 had been withdrawn from the agenda of the 107th GRSG session. GRRF agreed on the removal of the item from the agenda.

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.

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.
