4. The informal documents distributed during the session are listed in Annex I of the session report.

GRRF-78-02/Rev.2 | Updated agenda for the 78th GRRF session

GRRF/2014/18 | Provisional agenda for the 78th GRRF session

GRRF/2014/18/Add.1 | Annotated provisional agenda for the 78th GRRF session

5. The expert from OICA introduced GRRF-78-30, GRRF-78-32, GRRF-78-33, GRRF-78-34, GRRF-78-35, GRRF-78-36 and GRRF-78-37. 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.

GRRF-78-30 | Introduction of OICA proposal on AEBS-LDWS regulations Explanation of OICA's requests to exempt certain vehicles from mandatory AEBS and/or LDWS requirements due to their uses and the technical limitations of these systems. For example, the sensors used by the systems cannot operate reliably on certain special purpose equipment (such as snow plows) where the equipment and the nature of the operating environment are prohibitive.

GRRF-78-32 | Proposal for supplement 01 to the 00 series of amendments to UN Regulation No. 130 Proposal to modify the introductory comments of the LDWS regulation in order to emphasize the focus on highway driving and impracticality of deploying LDWS on certain types of vehicles such as off-road equipment or special purpose vehicles.

GRRF-78-33 | Proposal for supplement 01 to the original version of UN Regulation No. 130 (Scope) Proposal to modify the scope of the regulation in order to exempt certain vehicles from mandatory compliance with its provisions in cases where technical obstacles prevent the reliable use of lane-departure warning systems given the current state of the technology. This document includes a detailed explanation of the vehicle categories for exemption.

GRRF-78-34 | Proposal for supplement 01 to the original version of UN Regulation No. 131 (Introduction) Proposal to modify the introductory comments of this regulation to explain the rationale for the exemption of certain vehicles from mandatory compliance with its requirements.

GRRF-78-35 | Proposal for supplement 02 to the 01 series of amendments to UN Regulation No. 131 (Introduction) Proposal to modify the introductory comments in this regulation in order to explain the rationale behind the exemption of certain vehicles from mandatory compliance with its requirements.

GRRF-78-36 | Proposal for supplement 01 to the 00 series of amendments to UN Regulation No. 131 (Scope) Vehicle manufacturers are currently implementing AEBS on a large variety of models, e.g. to fulfil mandatory requirements of some Contracting Parties. This implementation work confirms the concerns which were brought up for discussion during the AEBS/LDWS informal group activities and sheds light on a number of technical issues that appeared when installing obstacle detection devices on some specific vehicles, in particular in case of huge technical diversity and where the vehicle environment can have negative impact on system reliability and on its ability to operate. This proposal would alter the regulation scope to exempt such vehicles from mandatory compliance.

GRRF-78-37 | Proposal for supplement 02 to the 01 series of amendments to UN Regulation No. 131 (Scope) Vehicle manufacturers are currently implementing AEBS on a large variety of models, e.g. to fulfil mandatory requirements of some Contracting Parties. This implementation work confirms the concerns which were brought up for discussion during the AEBS/LDWS informal group activities and sheds light on a number of technical issues that appeared when installing obstacle detection devices on some specific vehicles, in particular in case of huge technical diversity and where the vehicle environment can have negative impact on system reliability and on its ability to operate. This proposal would alter the regulation scope to exempt such vehicles from mandatory compliance.

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.

GRRF-78-16 | Terms of Reference for the GRRF informal group on Modular Vehicle Combinations (MVC)

GRRF-78-17 | Report from the informal working group on Modular Vehicle Combinations (MVC)

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).

GRRF/2013/13 | Proposal for collective amendments - Regulation Nos. 13, 13-H, 79, 89, and the LDWS and AEBS regulations Proposal for collective amendments of amendments to 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 Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

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.

GRRF-78-52 | Cross reference to Regulation No. 10 in Regulation No. 78 IMMA comments on the suggestion to include a cross reference to UN R10 in UN R78 in order to ensure that electromagnetic interference does not affect electronic brake modules in a way that causes unsafe brake operation as was adopted for UN R13.

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.

GRRF-78-40 | Report on the status of work on the issue of electro-hydraulic systems Status report, including the current state of the draft text, on efforts to reach agreement on the introduction of provisions for electro-hydraulic systems into the test conditions for trailers with electrical braking systems.

GRRF/2013/29 | Proposal for amendments to UN Regulation No. 13 Text prepared by Germany to clarify electrical braking system and energy supply line requirements with regard to towed trailers, including proposals for voltage specifications and inclusion of electro-hydraulic transmission devices within such systems. The text also seeks to align terminology with comparable paragraphs in other UN Regulations.

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.

GRRF/2004/11 | Proposal for a draft amendment to Regulation No. 13 Proposal to introduce new requirements for trailers braked by an inertia (overrun) braking system.

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.

GRSG-106-35 | Controls, Tell-tale and Indicators: Focus on common space regarding the current regulation Presentation concerning the asynchronous use of an indicator space for communicating information to the driver. The presentation explains the concept of this "common space" that two or more symbols may share but only use one at a time. The presentation proposes that two or more symbols might be displayed sequentially in the same common space (i.e., alternately flashing symbols).

GRSG/2014/12 | Proposal for Supplement 9 to Regulation No. 121 Proposal to adapt the provisions for multi-function displays to technological progress. In principle, current displays can convey more information to the driver, including levels of severity or importance, while the current text was written when technologies were less flexible. As a result, the current provisions risk impeding the use of beneficial multi-function tell-tales. This text is based on informal document GRSG-105-21.

15. The expert from CLEPA introduced ECE/TRANS/WP.29/GRRF/2014/27, proposing amendments to Annexes 10 and 13 of UN Regulation No. 13. GRRF adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions as draft Supplement 13 to the 11 series of amendments to UN Regulation No. 13.

GRRF/2014/27 | Proposal for an amendment to Regulation No. 13 Proposal based on informal document GRRF-76-21 to remove all references to Annex 10 from Annex 13 by transferring the provisions concerning vehicles with and without anti-lock braking systems to Annex 10.

16. The Chair of the IWG on UN Regulation No. 55 introduced ECE/TRANS/WP.29/GRRF/2014/28 (based on ECE/TRANS/WP.29/GRRF/2014/14) and deleting references to the standard ISO 7641/1‑2012 as contained in the original proposal.

GRRF/2014/28 | Proposal for Supplement 4 to the 01 series of amendments to Regulation No. 55 Text prepared by the informal group of experts on Regulation No. 55 to introduce amendments on requirements for movable couplings, increased range of application of remote controls to couplings similar to C50-X and G50-X, possible increase of characteristic values of standard couplings and to include of further requirements on the mounting of couplings.

17. The chair of the IWG on UN Regulation No. 55 introduced GRRF-78-23 explaining the differences between standards ISO 7641:1983 and ISO 7641:2012. He reported on the meeting minutes (GRRF‑78‑25) and on the meetings status on Task Force Agricultural Couplings (TFAC) (GRRF‑78‑26). Finally he presented GRRF‑78-24 as a complete revision of UN Regulation No. 55. GRRF agreed to resume consideration of this proposal at its February 2015 session.

GRRF-78-23 | Comparison of ISO 7641:1983 and ISO 7641:2012 The expert group on UN R55 submitted document GRRF/2014/14 to update the requirements for mechanical couplings, including a proposal to replace the references to IS0 7641:1983 with ISO 7641:2012. In response to issues raised within GRRF, the experts prepared a new proposal (document GRRF/2014/28). This document would supplement the proposal by providing additional information on the differences between the 1983 and 2012 versions of ISO 7641.

GRRF-78-24 | Consolidated working draft of UN R55 introducing provisions for agricultural vehicle couplings Copy of the latest working draft of UN R55 containing amendments to introduce provisions for agricultural vehicle couplings as of 2 June 2014 (document TFAC-04-11).

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.

GRRF/2014/23 | Proposal for amendments to Regulation No. 90 Proposal by Italy to introduce requirements for the approval of replacement brake discs for L-category (motorcycle and related) vehicles.

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.

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.

GRRF-78-27 | Proposal for amendments to document GRRF/2014/19 on Regulation No. 79 Proposal to clarify the draft text to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source. This proposal would clarify and reaffirm that where there is “a failure in the energy supply, the steering system shall have priority”.

GRRF-78-44 | Explanation of CLEPA's proposal concerning steering systems that share the same energy source with the braking system Supporting explanation for the proposal to align UN R79 with UN R13-H concerning cases where the braking and steering systems have the same energy source.

GRRF-78-28 | Proposal for amendments to document GRRF/2014/13 (tyre installation) Proposal to clarify the inflated run-flat tyres are within the scope of this regulation while uninflated run-flat tyres fall exclusively under UN R64 and to remove references to UN R64 since this regulation and UN R64 exist as independent parallel tyre regulations. The proposal seeks to improve the wording, including to align more closely with EU Regulation (458/2011).

GRRF/2014/13 | Proposal for a new Regulation on Tyre Installation Proposal for a new regulation for the approval to tires installed on a vehicle. This regulations is proposed for use within the International Whole Vehicle Type Approval system in order to ensure proper tire fitment on a vehicle under IWVTA evaluation. This document supersedes GRRF-75-20.

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.

GRRF-76-13 | Proposal for amendments to document GRRF/2014/12 (Draft ESC Regulation) Proposal to specify that safety aspects of ESC systems can be assessed under this new regulation or under UN R13-H. The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed ESC regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the ESC regulation.

GRRF-76-14 | Proposal for amendments to document GRRF/2014/11 (Draft BAS Regulation) Proposal to specify that safety aspects of brake assist systems can be assessed under this new regulation or under UN R13-H. The objective of the proposed wording is to avoid redundant certification of the complex electronic control systems (CEL) aspects of ESC according to both the proposed BAS regulation and UN Regulation No. 13-H (keeping unchanged the level of safety). The proposal would permit the applicant to show evidence that CEL compliance has already been achieved according to Annex 8 of UN Regulation No. 13-H as an alternative to demonstrating compliance with the CEL annex of the BAS regulation.

GRRF-76-18 | Addendum to document GRRF/2014/10 (Proposal to amend UN R13-H pursuant to the separate ESC/BAS regulations) Proposed amendments to UN R13-H to confirm that the complex electronic control system (CEL) requirements may be satisfied through an approval conducted under another regulation (e.g., the pending new ESC and BAS regulations) and to delete the marking requirement concerning ESC systems which will no longer be within the scope of UN R13-H.

GRRF-76-22 | Proposal for amendments to the draft regulation on Brake Assist Systems Proposal to amend the draft text for the proposed new regulation on BAS which would extract the BAS provisions from the current UN R13-H on light vehicle braking systems. The intention is to clarify the meaning of the text in places where it is ambiguous when taken out of the context of UN R13-H.

GRRF-76-23 | Proposal for amendments to the draft regulation on Electronic Stability Control Proposal to amend the draft text for the proposed new regulation on ESC which would extract the ESC provisions from the current UN R13-H on light vehicle braking systems.

GRRF-78-19 | Proposal for amendments to document GRRF/2014/12 (Draft ESC Regulation)

GRRF-78-20 | Proposal for amendments to document GRRF/2014/11 (Draft BAS Regulation)

GRRF-78-21 | Proposal for amendments to document GRRF/2014/10 (Regulation No. 13H splitting)

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.

GRRF-76-33 | Proposal for amendments to document GRRF/2014/11 (new BAS regulation) India noted an erroneous reference to "ESC" in the original document where "BAS" was clearly intended.

GRRF-76-34 | Proposal for a new Regulation on Electronic Stability Control (ESC) Proposed corrections and clarifications to the draft text of the new regulation to separate ESC provisions from Regulation No. 13-H (document GRRF/2014/12).

GRRF/2014/10 | Proposal for amendments to Regulation No. 13-H Proposal for amendments to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

GRRF/2014/11 | Proposal for a new Regulation on Brake Assist Systems (BAS) Proposal to transfer brake assist system systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-14.

GRRF/2014/12 | Proposal for a new Regulation on Electronic Stability Control (ESC) Proposal to transfer electronic stability control systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-15.

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.

GRRF-78-41 | CLEPA Proposal Associated with Annex CEL and its Application to Functions or Systems Defined within a Separate Regulation Presentation discussing the framework for relating independent regulations on electronic subsystems of braking or steering systems to the primary braking/steering regulations.

This proposal revises the wording, focusing on ESC systems with relation to the requirements for complex electronic control systems under Regulation 13-H.

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.

GRRF-78-38 | Proposal to amend UN Regulation No. 64 to remove tire pressure monitoring system provisions This proposal was prepared by OICA and is based on the existing UN Regulation No. 64. It is aimed at moving the Tyre Pressure Monitoring System provisions into a separate Regulation.

GRRF-78-39 | Proposal for a new UN Regulation concerning the approval of vehicles with regard to their tyre pressure monitoring systems This proposal was prepared by OICA and is based on the existing UN Regulation No. 64. It is aimed at moving the Tyre Pressure Monitoring System provisions in a separate Regulation.

GRRF-78-48 | Proposal for amendments to UN Regulation No. 64 Proposal to delete references to tire-pressure monitoring systems under UN R64 (with the intention to establish them as a stand-alone regulation). This document presents only the amendments and complements the earlier document GRRF-78-38 that presented the consolidated version of UN R64 amended as proposed here.

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.

GRRF-78-03 | Proposal for amendments to the Consolidated Resolution on the Construction of Vehicles (R.E.3) Proposal to add classifications covering agricultural trailers and towed agricultural machinery in the Consolidated Resolution on the Construction of Vehicles (R.E.3).

GRSG/2014/25 | Proposal for amendments to ECE/TRANS/WP.29/78/Rev.3 on the Consolidated Resolution on the Construction of Vehicles (R.E.3) Proposal to add classifications covering agricultural trailers and towed agricultural machinery in the Consolidated Resolution on the Construction of Vehicles (R.E.3).

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.

GRRF-76-03 | Abbreviations and Acronyms used in the UN Regulations of GRSP, GRRF (and other GRs) (1958 Agreement) Results from the project to review and eventually harmonized technical terms and abbreviations used across UN Regulations.

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.

GRRF-78-51 | UN Regulation No. 90 approval numbers and certification issue For testing purposes, UN R90 defines a "test group" as a grouping of parts having the same characteristics. The regulation then defines a "variant" as a part within a "test group". However, the approval numbers under the rule stipulate the identification of each variant certified. As a result, the text technically requires certification of each individual part (variant) which was not the intention of the drafters. CLEPA raises this for information purposes with the intention to put forward a proposal at the next GRRF 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.
