33. The World Forum recalled the oral report of the Chair of GRRF given during the 170th session (ECE/TRANS/WP.29/1126, paras. 37-41) and approved the report.

3. GRRF also adopted the running order for the session as proposed in GRRF-82-01. The informal documents distributed during the session are listed in Annex I of the session report.

Explanation of proposals from the informal working group for corrections, restructuring, and amendments to UN R55.

16. The Chair of the IWG on Regulation No. 55 presented (GRRF-82-02) a proposal (ECE/TRANS/WP.29/GRRF/2016/28) introducing amendments to Regulation No. 55 on secondary coupling and the attachment points. The expert from Italy responded to the proposal (GRRF-82-05). GRRF supported this proposal as amended and reproduced in GRRF-82-33.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable. This revised proposal takes into account comments received during the February 2016 GRRF session.

13. The expert from CLEPA presented ECE/TRANS/WP.29/GRRF/2016/27, as amended by GRRF-82-03. GRRF supported the aim of this proposal. The proposal received several comments of editorial nature. GRRF agreed to keep both documents on the agenda of the next GRRF session.

14. The expert from CLEPA presented ECE/TRANS/WP.29/GRRF/2016/27, as amended by GRRF-82-03. Following discussions, the experts from the European Commission and from CLEPA presented GRRF-83-31. GRRF agreed to resume consideration of this subject and requested the secretariat to distribute this informal document with an official symbol at its September 2017 session.

Request for authorization to develop amendments to GTR No. 3 in order to:

1. align GTR 3 with Supplement 3 to the 03 series of amendments to UN Regulation No. 78 adopted at June 169/WP.29 (electromagnetic compatibility requirements for ABS, application of ABS provisions to three-wheelers, installation of emergency stop signal) and
2. clarify the possibility to install a means to disable the ABS function (‘ABS Switch’) under certain conditions.

24. The expert from Italy consulted GRRF (GRRF-82-04) on a proposal to develop an amendment to GTR No. 3 on motorcycle braking. He informed that Italy, at the forty-eighth session of AC.3, would propose to sponsor this amendment, harmonizing the provisions of the GTR and those in Regulation No. 78, dealing with Electromagnetic Compatibility (EMC), tri-cycles Anti-lock Braking Systems (ABS), Emergency Stop Signal and means to disable the ABS function (‘ABS switch’). The expert from Canada pointed out potential challenges related to the absence of specific EMC testing requirements for braking systems and the obligation to justify why mandating the fitment of ABS on tri-cycles. GRRF supported the content of GRRF-82-04. The expert from Italy volunteered to request the authorization to develop Amend. 3 to GTR No. 3 at the forty-eighth session of AC. 3 in November 2016.

Comments concerning failure modes in the event of a separation of the main coupling between a vehicle and a towed trailer in order to enable the trailer to be guided and/or stopped automatically.

16. The Chair of the IWG on Regulation No. 55 presented (GRRF-82-02) a proposal (ECE/TRANS/WP.29/GRRF/2016/28) introducing amendments to Regulation No. 55 on secondary coupling and the attachment points. The expert from Italy responded to the proposal (GRRF-82-05). GRRF supported this proposal as amended and reproduced in GRRF-82-33.

Proposal for amendments to the draft 04 series of amendments to Regulation No. 78. The draft 04 series proposes to align UN R78 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. As agreed at the previous session, GRRF reviewed ECE/TRANS/WP.29/2016/114 proposing a new series of amendments to Regulation No. 78 (submitted to WP.29 and AC.1 for review and vote at their coming sessions). The expert from IMMA introduced GRRF-82-06-Rev.1, proposing three minor corrections. GRRF reconfirmed ECE/TRANS/WP.29/2016/114, adopted the editorial corrections, as reproduced in Annex III and requested the secretariat to submit it to WP.29 and AC.1, as an informal document amending ECE/TRANS/WP.29/2016/114 at their November 2016 sessions.

FIA comments on data privacy provisions under UN Regulations including remarks concerning the work of the informal groups on automated driving (ITS/AD), automatic emergency calls systems (AECS), and automatically commanded steering functions (ACSF). The presentation covers issues such as protection of personal data, aggregation of data to protect individual identities, protection against unauthorized access (hacking), and prohibition against data use for purposes other than those specifically intended by a regulation. FIA proposes the deletion of data storage (DSSA) provisions under the draft texts for ACSF.

57. The expert from FIA presented GRRF-82-07 on data privacy and cybersecurity of (partly) automated driving and on Data Storage Systems for ACSF (DSSA). He advocated against potential DSSA installation requirements for data protection and cybersecurity reasons as, to date, no clarity would be provided on consumer protective measures. He stated that such systems could facilitate the collection (also over-the-air, outside of the vehicle) and interpretation of a large amount of data, that could easily be used against the driver, in various situations (e.g. for commercial, warranty, recall and liability purposes). He urged therefore GRRF to ban such systems as long as no fair and balanced relations among stakeholders would be guaranteed.

Proposal to amend “option 4” as presented in the proposal introduce technical requirements for Corrective Steering Functions under UN R79 (document GRRF/2016/45). Option 4 for consideration by GRRF proposes to amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1. The proposal includes:

• Clarification of Corrective steering function (CSF) incl. defining of new requirements;
• Establishment of new categories for automatically commanded steering function (ACSF): Categories A, B1, B2, C, D and E;
• Wording for requirements of Category A (incl. remote parking RCP), and Category B1.

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF. The Secretary of the IWG on Automatically Commanded Steering Function (ACSF) gave a presentation reporting on the progress made by the group (GRRF-82-17). He reported on definitions proposed for ACSF of Categories A to E, clarifications proposed for Corrective Steering Functions (CSF) and new provisions proposed for RCP. GRRF acknowledged the status report received and agreed to work on an amendment to Option 4 as proposed by GRRF-82-12. The proposal for Option 4 received several comments in GRRF-82-08, GRRF-82-09, GRRF-82-14, GRRF-82-15, GRRF-82-18, GRRF-82-19 and GRRF-82-26.

66. The secretariat introduced GRRF-82-10 reporting on the GRRF relevant highlights of the 168th and 169th sessions of WP.29. For more information, please refer to the session reports (ECE/TRANS/WP.29/1120, ECE/TRANS/WP.29/1123).

Proposal, consolidating document GRRF-82-08 with the proposed test procedures, revising “option 4” as presented in the proposal introduce technical requirements for Corrective Steering Functions under UN R79 (document GRRF/2016/45). Option 4 proposes to amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1. The proposal includes:

• Clarification of Corrective steering function (CSF) incl. defining of new requirements;
• Establishment of new categories for automatically commanded steering function (ACSF): Categories A, B1, B2, C, D and E;
• Wording for requirements of Category A (incl. remote parking RCP), and Category B1.

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF.

Updated version of the draft amendment to introduce provisions for corrective steering and Category B1 ACSF into UN R79 based upon discussions held during the afternoon GRRF session of 21 September.

Updated version of the proposal to introduce corrective steering and B1 level ACSF provisions into UN R79 prepared pursuant to discussions held among interested parties following the afternoon GRRF session on 21 September.

Updated version of the proposal to introduce corrective steering and B1 level ACSF provisions into UN R79 as agreed by the GRRF during its September 2016 session.

56. GRRF adopted GRRF-82-12-Rev.3, subject to confirmation in January 2017 by GRRF, and requested the secretariat to submit it to WP.29 and AC.1 as a draft Supplement 6 to the 01 series of amendments to Regulation No. 79 (Steering equipment) for consideration and vote in March 2017.

During its 8th meeting (Stockholm), the ACSF informal group decided that all functions to “assist the avoidance of a collision” would be excluded from the definition of “Corrective Steering Function”. ACSF decided to establish a new definition for “Emergency Steering Functions (ESF)” with specific requirements. The intention was to draft this definition during a second phase effort through which requirements for ACSF categories beyond B1 will be established. In order to enable the approval of ESF systems critical to road safety, OICA has prepared this proposal for an ESF definition and simple requirements based upon provisions for Complex Electronics (CEL) in Annex 6. A footnote has also been added to define the specific conditions for the approval of these systems, until uniform provisions are defined by the ACSF informal group.

58. The expert from OICA presented GRRF-82-13 proposing the introduction of provisions applicable for Emergency Steering Functions (ESF). GRRF supported the proposal but noted the absence of objective testing requirements to verify the safe operation of such systems at the time of Type Approval. Therefore, GRRF invited the IWG on ACSF to develop provisions for ESF.

In order to enhance the safety of B1 corrective steering functions (by reducing the probability of driver over-reliance and misunderstanding of system limitations), OICA proposes a minimum value of 0.8 m/s² for maximum lateral acceleration in place of the draft 1 m/s² for the speed range between 100-130 km/h for M1 and N1 vehicles. OICA believes that this would ensure that a system is capable under all conditions of generating the required minimum acceleration.

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF. The Secretary of the IWG on Automatically Commanded Steering Function (ACSF) gave a presentation reporting on the progress made by the group (GRRF-82-17). He reported on definitions proposed for ACSF of Categories A to E, clarifications proposed for Corrective Steering Functions (CSF) and new provisions proposed for RCP. GRRF acknowledged the status report received and agreed to work on an amendment to Option 4 as proposed by GRRF-82-12. The proposal for Option 4 received several comments in GRRF-82-08, GRRF-82-09, GRRF-82-14, GRRF-82-15, GRRF-82-18, GRRF-82-19 and GRRF-82-26.

54. The expert from Sweden commented on GRRF-82-14 informing that road construction standards would define design requirements (inclination profile) leading to the road side forces corresponding to 1 m/s² and that this value was even higher on roads designed for low speed. GRRF adopted the value 0.8 m/² proposed in this document for ACSF of categories A and B1 only, as a strict minimum, noting that it was taking account of a 0.2 m/² measurement uncertainty and that the value 0.8 m/² would de facto impose manufacturers to design systems according to a higher value in practice.

Proposed changes to the draft amendments to UN R79 concerning ACSF B1 systems. The proposed new wording for the triggering condition of the warning (“any front tyre of the vehicle is crossing the lane marking”) is technically more specific than the original (“the vehicle is going to leave the lane”). The use of a haptic signal as an alternative to the acoustic signal achieves the goal pursued by Germany. This proposal is consistent with the warning strategy of AEBS specified in UN R131. In the case of M2 M3 N2 N3 vehicle categories, it is proposed to take as a base the requirements specified in UN R130 LDWS regulation, which achieves the goal.

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF. The Secretary of the IWG on Automatically Commanded Steering Function (ACSF) gave a presentation reporting on the progress made by the group (GRRF-82-17). He reported on definitions proposed for ACSF of Categories A to E, clarifications proposed for Corrective Steering Functions (CSF) and new provisions proposed for RCP. GRRF acknowledged the status report received and agreed to work on an amendment to Option 4 as proposed by GRRF-82-12. The proposal for Option 4 received several comments in GRRF-82-08, GRRF-82-09, GRRF-82-14, GRRF-82-15, GRRF-82-18, GRRF-82-19 and GRRF-82-26.

49. GRRF received an oral report from the Secretary of the IWG on Intelligent Transport Systems / Automated Driving on the outcome of the latest meeting that took place one day before the start of this GRRF session. The Secretary referred to GRRF-82-16 containing the latest document discussed with elements determining the definitions of automation levels. He noted that it was intended to be a living document delivering the conceptual framework, while GRRF was dealing with technical requirements. GRRF noted the importance of the work done by the IWG and supported the view expressed by the Chair on the necessity to allocate more time for this IWG in the framework of the WP.29 activities.

35. The expert from ETRTO presented ECE/TRANS/WP.29/GRRF/2016/38, proposing amendments on tyre markings, similar amendments to those proposed by the expert from France (see ECE/TRANS/WP.29/GRRF/2016/37) and harmonized provisions with those in another EU Regulation (namely Regulation EU 167/2013) which defines vehicles of Category S as “interchangeable towed equipment”. GRRF amended the proposal, as reflected in GRRF-82-24-Rev.1.

37. GRRF agreed with the proposals above (see paras. 35-36) and requested the secretariat to keep the documents on the agenda of its January 2017 session.

28. The expert from ETRTO introduced GRRF-82-25 presenting the conclusions of their considerations on the development of the Amendment No. 2 to UN GTR No. 16. The expert from the Russian Federation proposed his leadership to develop this amendment and consulted GRRF on the necessity to establish an IWG on the Tyre GTR. He then introduced GRRF-82-31 proposing draft Terms of Reference for the IWG. GRRF endorsed the proposal as reproduced in Annex IV. The expert from the Russian Federation volunteered to request the authorization to develop Amend. 2 to GTR No. 16 at the forty-eighth session of AC. 3.

Proposal to amend the consolidated draft amendment to UN R79 to introduce technical requirements for Corrective Steering Functions and Level B1 ACSF under UN R79 (document GRRF/2016/45).

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF. The Secretary of the IWG on Automatically Commanded Steering Function (ACSF) gave a presentation reporting on the progress made by the group (GRRF-82-17). He reported on definitions proposed for ACSF of Categories A to E, clarifications proposed for Corrective Steering Functions (CSF) and new provisions proposed for RCP. GRRF acknowledged the status report received and agreed to work on an amendment to Option 4 as proposed by GRRF-82-12. The proposal for Option 4 received several comments in GRRF-82-08, GRRF-82-09, GRRF-82-14, GRRF-82-15, GRRF-82-18, GRRF-82-19 and GRRF-82-26.

Corrections to the proposal by the informal working group on Regulation No. 55 concerning vehicle combination applications to introduce:
(a) An amendment for the separation of requirement calculation procedures from the procedure of setting and certifying performance values.
(b) An amendment that adds procedures for requirement calculation for vehicle combinations that have hitherto not been accounted for in the Regulation.

17. The Secretary of the IWG introduced ECE/TRANS/WP.29/GRRF/2016/29 (amended by GRRF-82-27) with technical requirements for coupling devices for the purpose of modular vehicle combinations as well as “in-use” requirements for the combination of vehicles. The proposal, supported by GRRF, received some comments about the possibility to verify, at the time of type approval, the compliance with these “in use” requirements. GRRF questioned whether a driver could be requested to verify during a coupling phase the compatibility requirements defined in the proposal. The expert from CLEPA showed that calculation tools were available on the website of his company (www.vbg.se) and argued that it would be possible. GRRF agreed that this aspect of the proposal would need further consideration by the IWG who should recognise that new measures must be enforceable via type approval.

20. The expert from Germany volunteered to prepare a consolidated document encompassing all documents above (see paras. 16-19) while addressing the comments received. GRRF requested for this new document to be brought to the next session.

Revised proposal superseding document GRRF/2016/31. Proposals in GRRF/2016/31 to regulate the articulation angles of couplings as installed have been removed. The informal group on UN R55 could not reach agreement on this subject. As a result, this revised proposal by the informal working group on Regulation No. 55:
a) Corrects an error in Annex 5, figures 12 and 17; and
b) Introduces an amendment concerning identification of worst cases for design assessment.

19. The Chair of the IWG introduced ECE/TRANS/WP.29/GRRF/2016/31 (as amended by GRRF-82-28) proposing clarifications and an amendment to the worst cases identification provisions. GRRF supported the proposal.

Presentation concerning the inability to test O₃ recreation vehicle trailers equipped with electric braking systems for type approval certification under UN R13.

15. The Chair of GRRF invited the expert from RVIA to present GRRF-82-29. The expert from RVIA presented his association (being to date in the Economic and Social Council (ECOSOC) NGO accreditation process) and explained the difficulties of its members to receive approvals for their products according to Regulation No. 13 and sought guidance from GRRF on ways to address the issue. The expert from CLEPA stated that the products mentioned would not comply with several essential provisions of Regulation No. 13 and suggested to delete recreational vehicles of the scope of Regulation No. 13. The Chair wondered whether an NGO not yet successfully holding an ECOSOC accreditation would be entitled to make proposal to GRRF. The Secretary referred to the discussion held at WP.29 at its June 2016 session (see ECE/TRANS/WP.29/1123, para. 14 [note: this refers in principle to discussions on the EU-Japan-US “trilateral paper” which identified involvement of all stakeholders in the development of regulations as a WP.29 priority.]) and the need to keep WP.29 informed.

22. The expert from Germany introduced the proposal for Terms of Reference of IWG on the Agricultural Coupling Devices and Components revised by the IWG (GRRF-82-30). GRRF adopted the proposal, reproduced in Annex II. The expert from Germany submitted GRRF-82-37 to GRRF, providing a status report of the IWGs’ activities.

28. The expert from ETRTO introduced GRRF-82-25 presenting the conclusions of their considerations on the development of the Amendment No. 2 to UN GTR No. 16. The expert from the Russian Federation proposed his leadership to develop this amendment and consulted GRRF on the necessity to establish an IWG on the Tyre GTR. He then introduced GRRF-82-31 proposing draft Terms of Reference for the IWG. GRRF endorsed the proposal as reproduced in Annex IV.

Proposal by the informal working group on Regulation No. 55 concerning vehicle combination applications to introduce:
(a) An amendment for the separation of requirement calculation procedures from the procedure of setting and certifying performance values.
(b) An amendment that adds procedures for requirement calculation for vehicle combinations that have hitherto not been accounted for in the Regulation.

17. The Secretary of the IWG introduced ECE/TRANS/WP.29/GRRF/2016/29 (amended by GRRF-82-27) with technical requirements for coupling devices for the purpose of modular vehicle combinations as well as “in-use” requirements for the combination of vehicles. The proposal, supported by GRRF, received some comments about the possibility to verify, at the time of type approval, the compliance with these “in use” requirements. GRRF questioned whether a driver could be requested to verify during a coupling phase the compatibility requirements defined in the proposal. The expert from CLEPA showed that calculation tools were available on the website of his company (www.vbg.se) and argued that it would be possible. GRRF agreed that this aspect of the proposal would need further consideration by the IWG who should recognise that new measures must be enforceable via type approval.

Proposal by the informal working group on Regulation No. 55 and introduces a procedure to identify allowable combinations of performance values DC and V for drawbar coupling equipment.
