27. The GRRF chair informed WP.29 about the submission by GRRF of the revised Terms of Reference and Rules of Procedures of the informal group on Automatically Commanded Steering Functions (ACSF) as reproduced in the annex of the session’s report.

28. The representative of OICA wondered why the IWG on ACSF was prioritizing its work on the complex Category E ACSF systems instead of starting with the more basic categories, and using the experience so gained to develop the requirements for the higher categories. The Chair of GRRF answered that the IWG had chosen a top down approach, starting with the provisions for the Category E to make sure that the relevant requirements cascade down through the other ACSF Categories. The representative of Germany added that no delay was expected because of the approach chosen and that with this approach, all ACSF categories would be addressed.

22. The World Forum recalled the oral report of the Chair of GRRF given during the 167th session (ECE/TRANS/WP.29/1118, paras. 26-29) and approved the report.

3. GRRF also adopted the running order for the session as proposed in GRRF-80-01. The informal documents distributed during the session are listed in Annex I of the session report.

2.

Proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts. The proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.050 mm (the common OEM specification).

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.

Documents GRRF/2015/40 and 41 propose to align GTR 3 and UN R78 with the provisions for anti-lock braking systems used in other regulations. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. IMMA wishes to make the wording more technology-neutral, clarify test conditions considered impractical, and allow time for manufacturers to comply (i.e., add transitional provisions).

24. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/40 and ECE/TRANS/WP.29/GRRF/2015/41, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions.

He announced the following meeting is scheduled on 26-27 October 2015 in Paris. GRRF endorsed the status report.

There were no additional comments during the plenary session of GRRF-80.

The group agreed not to spend too much time on steering and coupling since the primary mandate of the group is to focus on braking.

Proposal to ensure that coupling balls do not block rear lighting and/or registration plates. In line with the EU General Safety Rule, Annex IV specification for application of UN R55, couplings that might block lighting or plates must be removable, repositionable, and unlockable in order to make it easier for users to remove them or reposition them when not in use (e.g., towing a trailer.) Coupling balls that are so designed as to be unable to block lighting or plates may still incorporate locks and/or require tools to remove or reposition.

20. The expert from EC introduced GRRF-80-29 aimed at addressing the situation where coupling balls are installed right in front of registration plates or rear fog lamps. The proposal received some comments and the expert from EC agreed to submit a revised proposal to the February 2016 session of GRRF.

26. The expert from Italy presented GRRF-80-31, introducing ECE/TRANS/WP.29/GRRF/2014/23/Rev.2 and GRRF-80-37 and proposing requirements for the approval of replacement brake discs for L‑category vehicles, taking into consideration the latest technologies available in the market as well as comments received during the previous session of GRRF. GRRF adopted the proposal with the following amendments:

(a) the proposed transitional provisions (paras 12.1 to 12.6) shall be deleted;
(b) The note under Table A15/2.9 shall read: “There are no groups…”

Under the International Whole Vehicle Type Approval (IWVTA) program, brake assist systems (BAS) and electronic stability controls (ESC) would be separated from UN R 13-H into new stand-alone regulations. This document has been prepared by an ad hoc group in order to ensure adequate transitional provisions to enable Contracting Parties to adapt to the new approach.

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.

IMMA presentation regarding the intention to propose emergency stop signal (ESS) provisions to UN R78 and GTR No. 3. ESS, which automatically activates hazard warning lights during forceful braking situations, already exists under UN R13-H for cars and trucks.

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).

In the framework of the International Whole Vehicle Type Approval (IWVTA) discussion, it was agreed to split Regulation No. 13-H into three distinct Regulations: on Braking, on Brake Assist Systems (BAS) and on Electronic Stability Control (ESC). In order to complete this task and to ease the implementation work of Contracting Parties relying on the existing text of the Regulation to mandate BAS or ESC, new transitional provisions are proposed.

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.

Proposal to introduce amendments to the test procedure and installation requirements of couplings belonging to classes K and L.

17. The Chair of the IWG on Regulation No. 55 introduced ECE/TRANS/WP.29/GRRF/2015/34, ECE/TRANS/WP.29/GRRF/2015/35, and ECE/TRANS/WP.29/GRRF/2015/36 presenting the outcome of the work done by the group and taking into account the comments received at the previous sessions of GRRF.

18. GRRF adopted the proposals, as reproduced Annex III (based on GRRF-80-41) to the session report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 55.

Proposal draft by the informal group on UN Regulation No. 55 to update this regulation with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

17. The Chair of the IWG on Regulation No. 55 introduced ECE/TRANS/WP.29/GRRF/2015/34, ECE/TRANS/WP.29/GRRF/2015/35, and ECE/TRANS/WP.29/GRRF/2015/36 presenting the outcome of the work done by the group and taking into account the comments received at the previous sessions of GRRF.

18. GRRF adopted the proposals, as reproduced Annex III (based on GRRF-80-41) to the session report and requested the secretariat to submit them to WP.29 and AC.1 for consideration at their March 2016 sessions, as Supplement 5 to the 01 series of amendments to Regulation No. 55.

Proposal to clarify and align the wording of Regulations Nos. 79, 13-H and 13.

The current text of Annex 3 of UN Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4.), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13-H. Paragraph 1.1.2. of Annex 4 to Regulation No. 13-H requires the capacity of a certain number of sudden stops after the energy source failed ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.2.

The current text of Annex 3 of Regulation No. 79 covers requirements to be met in case the braking and the steering systems have the same energy source (paragraph 5.3.1.4), and the same energy supply (paragraph 5.3.1.5.). However these requirements are not aligned with those of Regulation No. 13. Paragraph 1.1.3. of Annex 7 to Regulation No. 13 requires the capacity for the system of a certain number of sudden stops, after the energy source failed, ONLY in the case where the secondary braking performances cannot be met without energy assisting the muscular energy: see paragraph 1.1.3.

The current text of the provisions in Regulation No. 79 could be interpreted as the required number of sudden stops that must be achieved irrespective of the service braking design, i.e. even in the case of assisted braking system.

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:

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.

Proposal to change the measurement units for drum speed from min^-1 to km.h^-1 in alignment with the requirements with other tyre regulations. The proposed text also aligns wording in Annex 7, Appendix 1 with the text of the Regulation.

40. The expert from the Slovak Republic introduced ECE/TRANS/WP.29/GRRF/2015/38 as amended by GRRF-80-15. GRRF agreed that only proposed minor correction to footnote 2 in Annex 7, Appendix 1 would be relevant. At the request of the Chair of GRRF, the expert from ETRTO agreed to introduce it in its revised proposal for amendments to Regulation No. 54 to be reviewed by GRRF at its February 2016 session.

Proposal to change the measurement units for drum speed from min^-1 to km.h^-1 in alignment with the requirements with other tyre regulations. The proposed text also aligns wording in Annex 7, Appendix 1 with the text of the Regulation. The proposal also corrects a reference to para. 3.2.13. of the Regulation and an incorrect boundary value of load index.

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.

Proposal to align the text with the provisions for anti-lock braking systems used in other regulations. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.

24. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/40 and ECE/TRANS/WP.29/GRRF/2015/41, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions. The expert from Canada submitted an alternative wording (GRRF-80-19) and recalled that an authorization from the Executive Committee AC.3 for developing an amendment to GTR No. 3 would be required. The proposal received some general comments related to road safety. The expert from IMMA briefly introduced GRRF-80-13 commenting the proposals to which the expert from EC responded (GRRF-80-24 and GRRF-80-25). A majority of experts expressed a specific concern related to condition (f). The expert from EC volunteered to prepare two revised proposals for the [February 2016] session of GRRF.

Proposal to align the text with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.

23. GRRF reviewed ECE/TRANS/WP.29/GRRF/2015/41 and GRRF-80-24 under agenda item 5(b) below.

24. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/40 and ECE/TRANS/WP.29/GRRF/2015/41, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions. The expert from Canada submitted an alternative wording (GRRF-80-19) and recalled that an authorization from the Executive Committee AC.3 for developing an amendment to GTR No. 3 would be required. The proposal received some general comments related to road safety. The expert from IMMA briefly introduced GRRF-80-13 commenting the proposals to which the expert from EC responded (GRRF-80-24 and GRRF-80-25). A majority of experts expressed a specific concern related to condition (f). The expert from EC volunteered to prepare two revised proposals for the [February 2016] session of GRRF.

21. GRRF agreed with the proposal of the expert from EC to reintroduce ECE/TRANS/WP.29/GRRF/2015/41 under agenda item 5(a) and to reconsider the proposal clarifying the possibility to install means to disable the ABS function in certain conditions for L-category vehicles. The expert recalled that a majority of experts expressed specific concerns related to the condition (f) in the proposal at the previous session and therefore agreed to delete it, as shown in GRRF-81-28. The proposal, received some comments to amend the text in a more stringent manner. The expert from IMMA advocated for transitional provisions aligned with those of Euro 5 in Europe. He added that the newly proposed wording was too restrictive and may exclude some vehicles that were already equipped with the feature. GRRF agreed therefore on longer transitional provisions for existing vehicle types, and also to not excessively restrict the kind of vehicle that could be equipped with the ABS off switch function, by softening the wording of these provisions. The Contracting Parties agreed on the amended proposal GRRF-81-28-Rev.1. The expert from Italy expressed a scrutiny reservation on the provisions related to the off road switch. GRRF adopted the proposal as reproduced in Annex III and requested the Secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as a new 04 series of amendments to Regulation No. 78, subject to final review by GRRF in September 2016.

Proposal to include three-wheeled category l vehicles within the scope of ABS testing under UN R78. This would align the scope with EU Directive 93/14/EEC.

22. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/42, 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 L6 and L7 category vehicles, some experts were of the opinion that transitional provisions would be necessary. The expert from EC volunteered to prepare a revised proposal for the February 2016 session of GRRF.

22. The expert from EC recalled the purpose of ECE/TRANS/WP.29/GRRF/2015/42, proposing to apply to tricycles the existing Anti-lock Braking Systems (ABS) requirements for Powered Two Wheelers (PTWs). The experts from IMMA and OICA agreed with the proposal. GRRF adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their June 2016 sessions, as part of the Supplement 3 to the 03 series of amendments to Regulation No. 78.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

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

Proposal to extend the possibility of actuating the service braking system to vehicles of categories M2 and N2 below 5t.

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.
