Addendum 1 to the Report of the GRRF on its 86th session

Proposal of requirements for L category vehicles. The original proposal addressed a broader range of issues and could not be finalized during the GRRF session. This document allows items where consensus was reached to move forward for WP.29 consideration.

Proposal to add replacement brake components for L₆ and L₇ (quadricycles) to the regulation, to correct references, and to clarify the text. This proposal aligns UN R90 with UN R78 (motorcycle braking).

Proposal as approved by GRRF to add tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed under UN Regulation No. 106 in order to permit their type approval in conformity with Regulation EU 167/2013 for imported tyres. The proposal adds kPa marking specifications for use in measurements and tyre testing. The proposal further includes changes to the text and addition of tyre size designations to Annex 5 and Annex 7:

1. Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7
2. Paras 3.2., 3.2.2. and 5.4. modified because “tyres submitted for approval” cannot bear an approval mark until approved and the “only” as it is written can be misunderstood. Para. 3.2.2. was aligned to the wording in other UN Regulations. Reference to para. 3.3 in paragraph 5.4. is deleted because paragraph 3.3 does not refer to specific markings
3. Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote
4. Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements
5. The amendment of Annex 5, Table 5 adds the value for the overall diameter (D) in column (*) that applies to tyres marked with classification code “I-3”
6. Annex 5, Table 6, Note 1 amended because most of the tyre sizes listed in the table, especially those identified by the “classification code I‐3” (i.e. Traction tread), are currently available in both versions: ‘implement’ to be used on agricultural machinery and ‘IND’ to be used on construction vehicles. The two types of tyres have the same type of size designation and the same dimensions. Therefore some manufacturers identify those tyres with the suffix ‘IND’ rather than with the suffix ‘IMP’ thus applying the variation of load capacity with speed as published in Annex 7 Part E. The reason for this proposal is to avoid a duplication of tables with a new table only replacing the suffix IMP with the suffix IND.
7. The addition of the footnote to Annex 5, Table 7 answers the request by GRRF to introduce appropriate formulae in the Regulation instead of continuously updating Annex 5.
8. References in Annex 7 corrected pursuant to the renumbering following the introduction of three new paragraphs in Supplement 15 approved during the 172nd session of WP.29.
9. Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.

Proposal as approved by the GRRF to introduce formulae for tyre sizes in Annex 5, Table B, add sizes in Annex 5, Part II, Tables C and E for old sizes that do not follow the guidelines/formulae applicable for high flotation tyres, amends footnotes in Annex 5, Part II, Table B in order to clarify categories of use, clarify tyre width tolerances, correct paragraph numbering and references, align the text editorially with UN R30 and to make other editorial improvements,

Changes and notes made to the ACSF informal group status report as part of the GRRF discussion on how to deliver approval requirements for ACSF B2 (lane-keeping at Level 3 automation) within the prescribed mandate of the group. The ACSF group is expect to deliver a draft text within the next nine months.

CLEPA presentation on the type approval process for replacement brake pads, linings, and drums and the impact of the new approval numbering system adopted under Revision 3 to the 1958 Agreement on approvals and markings of these products.

Proposal to resolve inconsistencies present from Supplement 2 to the 02 series of amendments resulting from the approval of proposals in documents GRRF/2014/23/Rev.2, GRRF/2015/22 and GRRF/2016/22. The proposal also introduces provisions for L category (motorcycle and related) vehicles.

Annex 1 of UN R55 concerns the type approval communication form. Item 9.3. requires information “For Class A mechanical coupling devices or components, including towing brackets”. Poland proposes to add “if fitted” to the description in order to avoid interpretations that brackets must be part of the approval (i.e., the approval may concern the coupling ball without additional attachments).

Updated version of document GRRF/2017/14 to amend UN R78 with regard to stop lamp activation. IMMA has proposed (document GRE/2015/42) to allow stop lamp activation under UN R53 through means other than application of the brakes (e.g., by electric vehicle regenerative braking). This proposal accordingly amends UN R78 regarding generation of the brake signal.

Revision 7 of Regulation No. 13 includes a former version of Figure 1B which was changed with Amend 4 to Revision 6 of UN Regulation No. 13. This correction is also needed for Revision 8, which contains the same error.

Revised proposal concerning remote-controlled parking (RCP). The new series 02 of Regulation 79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. The second proposal in the original document concerning regenerative braking and stop lamp activation will be discussed again as a revised formal document at the September 2018 GRRF session.

Proposal to add a paragraph to define the purpose of the “SS” marking introduce by the amendments to UN R106 on agricultural and related off-road tyres.

Germany proposed, in document GRRF/2017/24, to require automatic reactivation of a manually deactivated automatic braking system. One concern with the proposal invoked the need for prolonged deactivation under certain circumstances, such as when a vehicle is fitted temporarily with a snow plow. This proposal would explicitly require AEBS to be capable of detecting a blocked sensor (already implicit in the regulation) such that AEBS would not reactivate in such cases.

TyreGTR informal group presentation of Amendment 2 to the GTR on tires.

Marked up text of the tyre GTR Amendment 1 with improvements to the text (Phase 2A in the development of the regulation).

Norwegian request for GRRF comments on protection of steering gear and attachment to heavy vehicle frames. In a collision in Norway, the steering gear detached from the vehicle frame following a frontal collision such that the driver could no longer control the vehicle. Norway seeks input on strengthening the protection of steering gear in order to avoid such a situation.

Correction of a cross-reference error in the original documents GRRF/2018/5 and GRRF/2018/11.

Pursuant to Supplement 21 to UN R54 replacing PSI with kPa to indicate tyre inflation pressures, UN R109 requires updating. This proposal would allow both markings under UN R109 because the life cycle of the carcasses spans several years.

Proposal to correct a mistake in Supplement 17 to UN R75 (adopted document WP.29/2017/8). Annex 7, Paragraph 1.2., Footnote 1 should refer to UN R54, not UN R106.

Proposal to amend footnotes in Annex 5, Part II, Table B in order to clarify categories of use.

Session agenda updated pursuant to the latest informal document submissions.

The European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) requires vehicles to be equipped with a speed limitation device compliant with UN R89. UN R89 refers to speed limitation devices (SLD) and speed limitation functions (SLR) (i.e., aims to be technologically neutral). Russia requests GRRF confirmation that compliance with UN R89 can be achieved through either an SLD or SLF.

Possible scenarios for developing regulatory provisions for snow tyres under UN tyre regulations.

OICA counter-proposal to address the German concern over manual deactivations of AEB systems. The original document (GRRF/2017/24) proposed automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h. OICA proposes reactivation after 15 minutes of continuous operation at a speed above 70 km/h.

Proposal from Germany and the Republic of Korea to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

Revised proposal from OICA pursuant to comments received during the previous GRRF session to

1. exempt cases where the driver has temporarily deactivated the speed limiter from the warning requirement for excess speed in in order to reduce driver distraction
2. introduce throttle control via adjustment of the accelerator pedal position
3. to correct an editorial error in paras. 5.2.5.4.2. and 21.2.5.4.2.

Proposal of amendments to the proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems, defined as driver-actuated systems on off-road vehicles used for navigating exceptionally difficult terrain. OICA seeks to cover remote control applications for low speed manoeuvring not addressed in the original UK proposal.

This document presents two proposals. (1)The new series 02 of Regulation 79 introduced requirements for RCP (remote controlled parking) systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. (2) Proposal to permit illumination of the stop lamp for electric regenerative braking under 0.7m/s² deceleration in order to allow for “one-pedal driving” of electric vehicles.

A field study on tyre inflation pressures and TPMS fitment on passenger cars carried out in Sweden, Germany and Spain between November 2016 and August 2017. The study is the first of its kind worldwide covering all types of TPMS and taking into account the specific tyre inflation pressure recommendations for cold tyres as well as the actual tyre temperatures at the time of measurement.

Report on the development of AEBS requirements for light vehicles, including a note on the intention to seek GRRF approval for a new regulation on M₁/N₁ vehicle AEBS separate from the current UN R131 on heavy-duty vehicle AEBS.

Revised proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

Revised technical report to accompany the proposal for amendment 3 (concerning mainly ABS issues) to GTR 3.

Discussion of run-flat tyres and extended mobility tyres (EMT) in support of a general proposal to establish approval procedures for EMT under UN R30 and include EMT as “emergency mobility equipment” under UN R64. The proposal makes reference to recent activity on ISO 16992 regarding EMT test protocols.

Introductory statement to document GRRF-86-04 proposing amendments in order to provide a legal approval framework for extended mobility tyres under UN R30 and their recognition as “emergency mobility equipment” under UN R64.

Report of the expert group on agricultural coupling devices and components on the development of a new UN Regulation.

Proposal to correct Revision 2 of UN R55 to align with the text of Supplement 04 to 01 series of amendments. This proposal removes a subparagraph under paragraph 13.1 that should not have been included in the Revision.

Updated text of provisions from the informal group on ACSF for the approval of emergency steering functions and driver-initiated automated lane changing systems.

Proposal of provisions for the approval of emergency steering functions under Regulation No. 79.

Proposal to cease approvals under the 02 series of amendments from September 2020 in order to allow manufacturers adequate time to adapt to the new requirements;

• ESF, ACSF C and unexpectedly ACSF B1 (despite originally assumed to be compatible with ACSF C new requirements),
• new CEL assessment (documentation, tests…) whose scope is also extended to all non-complex electronic systems under series 03.

Regarding the application to “All Types” (e.g. for new registration), industry proposes to leave unchanged the existing vehicles on the market which are approved on the base of national of regional exemptions by Contracting Parties signatories of the UN R79 regulation, given the heavy technical impacts on ACSF C (sensor range…) which are indirectly affecting ACSF B1 systems that were initially assumed to be compatible with cat. C (e.g. 3s hands-off detection instead of 15s, lane centering prior to the lateral movement towards the marking etc.), and the add-on of requirements restricting design possibilities without clear safety benefits (e.g. the use of direction indicators to suppress the procedure).

Japan comments on the changes agreed by the informal group of experts which reviewed the content of Annex 6 and proposed (via document GRRF-85-1/Rev.1) to clarify the purpose of Annex 6 and ensure its suitability when used in the assessment of steering systems featuring advances in automation (i.e., ACSF). The proposal

1. corrects an editorial error by inserting a missing clause in paragraph 1, and
2. deletes the phrase “at least 10%” from paragraph 4.1.1. which changes the current meaning of text with regard to assessment of “the System”
   • Japanese technical services already verify each declared function by the manufacturer under the paragraph,
   • The wording “at least 10%” may result in a decrease in the number of tests where Japan believes number of tests should be decided by the Technical service considering which tests should apply.

Consolidated version of UN R106 including ETRTO proposed amendments (see documents GRRF/2018/6 and GRRF/2018/7).

This document presents changes agreed by an informal group of experts reviewing the content of Annex 6 since the 84th session of GRRF. The proposal aims to clarify the purpose of Annex 6 and ensure its suitability when used in the assessment of steering systems featuring advances in automation (i.e., ACSF).

Formal proposal from the ACDC informal group for consideration by GRRF for a new Regulation on uniform provisions concerning the approval of mechanical coupling components of combinations of agricultural vehicles.

This document consolidates previous documents GRRF/2017/19 and informal document GRRF-84-17 taking into account the request for addition of tyre sizes and tyre classification codes common in the United States and standardised by the Tire and Rim Association, but needed to be added to UN Regulation No. 106 in order to permit their type approval in order to conform to Regulation EU 167/2013 for tyres to be exported to Europe. It includes addition/modifications of some paragraphs to the main text of the Regulation as well as the addition of some tyre size designations to Annex 5 and Annex 7:

1. ISO 4251-4 replaced by ISO 18805
2. Paragraph 2.33.2 deleted since new tables for IF and VF were added to Annex 7
3. Paras 3.2., 3.2.2. and 5.4. modified because “tyres submitted for approval” cannot bear an approval mark until approved and the “only” as it is written can be misunderstood. Para. 3.2.2. was aligned to the wording in other UN Regulations. Reference to para. 3.3 in paragraph 5.4. is deleted because paragraph 3.3 does not refer to specific markings
4. Para 6.1.2. amended to align the wording to the headers in Annex 5 and to correct the reference to the footnote
5. Para 6.2.1. amended to restore the proper references after renumbering resulting from the latest Supplements
6. The amendment of Annex 5, Table 5 adds the value for the overall diameter (D) in column (*) that applies to tyres marked with classification code “I-3”
7. Annex 5, Table 6, Note 1 amended because most of the tyre sizes listed in the table, especially those identified by the “classification code I‐3” (i.e. Traction tread), are currently available in both versions: ‘implement’ to be used on agricultural machinery and ‘IND’ to be used on construction vehicles. The two types of tyres have the same type of size designation and the same dimensions. Therefore some manufacturers identify those tyres with the suffix ‘IND’ rather than with the suffix ‘IMP’ thus applying the variation of load capacity with speed as published in Annex 7 Part E. The reason for this proposal is to avoid a duplication of tables with a new table only replacing the suffix IMP with the suffix IND.
8. The addition of the footnote to Annex 5, Table 7 answers the request by GRRF to introduce appropriate formulae in the Regulation instead of continuously updating Annex 5.
9. References in Annex 7 corrected pursuant to the renumbering following the introduction of three new paragraphs in Supplement 15 approved during the 172nd session of WP.29.
10. Annex 7, Part A amended to conform with Tire and Rim Association specifications for code designated diagonal tyres with speed symbol A8.

Proposal to add markings for the inflation pressure to be used for measurements and tests.

Proposal to introduce provisions for the approval of retreaded tyres marked with the alpine symbol (“3PMSF” or “snowflake symbol”).

In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of “new tyres” Regulations, this amendment:

1. Indicates that for the purpose of this Regulation “tyres” means “pneumatic tyres”, so all the text has been reviewed
2. Introduces a definition of :
   • “retreader” copy based on that “manufacturer” in the tyres regulations
   • Brand name", “Trademark”, “Trade description” and “Commercial name” as defined in the tyre regulations
   • Material manufacturer / material supplier
3. Takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres
4. Aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations

Consolidated version of UN R54 incorporating the proposed amendments in document GRRF/2018/5.

Proposal to clarify the purpose of UN R139 which was originally established through the extraction of brake assist system (BAS) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the BAS provisions were written to assess performance in cases where a vehicle was fitted with a brake assist system. As a stand-alone regulation, UN R139 applies only to vehicles that are equipped with BAS. Therefore, this supplement proposes to refine the text to remove the “if fitted” language and ensure that UN R139 can only be applied to a vehicle equipped with a BAS.

Proposal to remove “if fitted” language from the text to clarify that UN R140 can only be applied to a vehicle equipped with a ESC system. UN R140 was originally established through the extraction of electronic stability controls (ESC) provisions from UN R13-H on brake systems. Within the context of UN R13-H, the ESC provisions were written to assess performance in cases where a vehicle was fitted with an electronic stability control system. As a stand-alone regulation, however, UN R140 applies only to vehicles that are equipped with ESC. The proposal also would correct an apparent error in to Annex 4, paragraph 2.1. where the reference to “ISO 15037 Part 1:2005” should read “ISO 15037 Part 1:2006”.

Proposal to introduce formulae for tyre sizes in Annex 5, Table B, add sizes in Annex 5, Part II, Tables C and E for old sizes that do not follow the guidelines/formulae applicable for high flotation tyres, clarify tyre width tolerances, correct paragraph numbering and references, align the text editorially with UN R30 and to make other editorial improvements,

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems, defined as driver-actuated systems on off-road vehicles used for navigating exceptionally difficult terrain. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate off-road and the off-road location is confirmed throughout the whole period that the function is in use.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF).

Proposal to correct the paragraph numbering of the original proposal for amendments to Regulation No. 54 contained in document GRRF/2017/18. The introduction of new paragraphs by Supplement 21 and the separation of paragraph 3.1. into subparagraphs 3.1.1. and 3.1.2. result in the proposed paragraph 3.1.12. being renumbered as 3.1.13.

Proposal as approved by GRRF during its 84th session to correct references to paragraphs in Regulations Nos. 30 and 54 which need updating pursuant to renumbering in the source regulations.

Draft amendment to UN R79, including provisions for emergency steering functions (ESF), Category C[1] ACSF for lane-change maneuvers, and updating of Complex Electronic Systems (CEL) Annex 6 provisions. This document was prepared during the 84th GRRF session for consideration during the special 85th GRRF scheduled to finalize a proposal for automated lane-change systems.

Speadsheet tool designed to calculate time and distance requirements based upon speeds of vehicle under test and test target motorcycle under the proposed procedures for evaluating Category C[1] ACSF automated lane-change systems.

Presentation by the WP.1 chairperson of traffic regulator perspectives on automated driving, cybersecurity, and related subjects.

Revised proposal, as approved during the 84th GRRF session, to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

Diagram illustrating the phases of a lane-change maneuver as envisioned by the Category C¹ ACSF amendment to UN R79.

Set of diagrams illustrating the phases and timing of the test procedure for an automated lane-change maneuver as envisioned by the draft amendment to introduce Category C¹ ACSF into UN R79. These figures include the vehicle under test and approaching motorcycle speeds and distances under the lane-change phases, including timing and duration of each phase.

Vehicle manufacturer perspectives on the permissibility of non-driving activities by the operator of a highly automated vehicle. This presentation relates to discussions between traffic regulators (represented by UN Working Party 1) and vehicle regulators (represented by UN Working Party 29) on responses under traffic laws and vehicle regulations to the advent of automated driving systems.

OICA presentation on a field study undertaken to collect data on tyre pressures of vehicles in use towards assessing the effectiveness of direct and indirect tyre-pressure monitoring systems on the maintenance of correct inflation levels.

Proposal to allow adaptation of speed and distance calculations in accordance with national speed limits since some nations enforce maximum speed limits below the 130 km/h used as the basis for the proposals on automated lane-change systems. Japan expects to refine the proposal in order to address mutual recognition concerns inherent in such recourse to national requirements. Japan further proposes clarification of the approaching vehicle (motorcycle) test target pending development of uniform test target specifications.

OICA/CLEPA comments on the proposal to restrict manual deactivation of AEB systems to speeds under 30 km/h, noting cases where, given the current state of the technology, manual deactivation (regardless of speed) is warranted.

This proposal supplements proposal GRRF/2017/23 which amends UN R13, R13H and R140, to allow the use of the ESC tell-tale to indicate the intervention on the steering angle of one or more wheels for the purpose of vehicle stability. The intention allow design options that avoid two optical warning signals (ESC flashing + constant CSF) during an ESC intervention.

Draft proposal to enable the approval of automated emergency steering systems intended to avoid or mitigate collisions. The proposal based on document ACSF-14-07 submitted by OICA and CLEPA which was discussed during the 14th meeting of the ACSF informal group. The square brackets indicates paragraphs which are still under discussion in the informal group.

Comments submitted to GRRF through the secretariat proposing amendments to the draft text on automated lane-change systems.

Presentation on remanufactured brake calipers as part of the discussion on whether such products should be subject to a new UN Regulation separate from UN R90. CLEPA does not believe these products require a new regulation.

Correction of a reference used in the original proposal for a new UN Regulation on agricultural vehicle couplings. In Annex 6, paragraph 1.7., 3.3.6. and 3.7.1.: The Term F_s is not needed and misleading. The vertical component of the test force is named F_v. This term should be used throughout the whole document concerning the vertical component of the test forces.

Working draft from the ACSF informal group to enable the approval of driver-initiated automated lane-change systems under UN R79.

Category G vehicles (defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3)) have specific characteristics that enable them to achieve traction on, and to traverse over, off-road terrain that would defeat and/or damage conventional road vehicles. In some situations, it would be safer for the driver to be able to manoeuvre the vehicle from outside. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate in this environment and the off-road location is confirmed throughout the whole period that the function is in use.

Proposal to

1. delete paragraph 3.1.15.3 as it is an unnecessary provision under self-certification systems and addresses deceleration measurement criteria referenced elsewhere in the regulation
2. clarify that the ABS tell-tale must be yellow
3. delete the prohibition on defeat devices due to the absence of objective and repeatable procedures for assess conformity necessary under self-certification.

Proposal to develop additional provisions under GTR No. 16 to allow for its alignment with Chinese tyre regulations.

Marked up version of GTR 16 identifying different requirements between the GTR and China’s tyre regulations.

Proposal of amendments to clarify the original text as proposed in GRRF/2017/14.

Information document submitted by the informal group on Complex Electronic Systems concerning work on clarifying Annex 6 of UN R79, especially with regard to the assessment of automated steering systems. A revision to paper, based upon a further meeting of the informal group, will be provided to GRRF-84. Please note that the phrase “Amend paragraph 5.1.10., to read:” should read “Amend paragraph 5.1.11”.

Proposal to correct erroneous cross-references in the original proposal GRRF/2017/17.

Proposal of additional footnotes to clarify terminology differences between the US and Europe to aid in the application of the regulation.

Proposal for new tables covering shallow-tread drive wheel tyres for agricultural tractors – normal section sizes and for additional specifications for high flotation tyre dimensions.

Proposal for extend the current mandate of the informal group until September 2018.

Highlights of the 171st (March 2017) and 172nd (June 2017) sessions of the World Forum relevant to the work of GRRF.

Report of the TyreGTR informal group chair on the group’s 16th session held in Moscow.

Objectives and rules of procedure for the informal group established to expand the scope of UN R131 to include M₁ and N₁ vehicles. The informal group proposal leaves open the option to develop AEBS requirements for these vehicles as a new UN Regulation.

Proposal to clarify the intent and rationale behind the proposal to simplify the verification of sufficient movement on the balancer without having to take measurements underneath the trailer in a potentially unsafe position.

Proposal to align the Russian text with the original English text. In the English versions, the title of Annex 1 (Communication concerning the approval or extension or refusal or withdrawal of approval or production definitely discontinued of a retreading production unit pursuant to Regulation No. 108) is essentially identical to that use for Annex 1 of UN R109. Therefore, this proposal amends the title of Annex 1 in the Russian version of UN R108 to coincide with that of the Russian version of Annex 1 in UN R109.

Proposal to restrict manual deactivation of AEB systems to speeds under 30 km/h. The proposal would require automatic reactivation of the AEBS when the vehicle speed exceeds 30 km/h.

Proposal to simplify the verification of the sufficient movement on the balancer without having to take measurements underneath the trailer in a potentially unsafe position.

Proposal from the informal working group on Agricultural Couplings.

Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

Technical report to accompany the proposal for amendment 3 (concerning mainly ABS issues) to GTR 3.

Proposal to update a cross-reference in paragraph 3.4. to read “3.1.2” pursuant to the earlier division of paragraph 3.1 into separate paragraphs 3.1.1. and 3.1.2.

Proposal to

1. correct the references to paragraph 3.17 in paragraph 3.1.12. to refer to 3.20
2. update a cross-reference in paragraph 3.4 to read “3.1.2.” pursuant to the earlier division of paragraph 3.1 into paragraphs 3.1.1. and 3.1.2. (consistent with UN R30)
3. delete the superfluous reference to paragraph 2.19 in paragraph. 4.1.1. (consistent with UN R30)
4. delete the word “existing” from paras. 6.1.1.2. and 6.1.2.2. (consistent with all the other tyre UN Regulations)
5. amend paragraph 6.1.4.2. to take into account the requirements for size designations in Annex 5
6. add a footnote to Annex 5, Part II, Table B to introduce the appropriate formulae in the Regulation (instead of Annex 5)
7. add a size in Annex 5, Part II, Table C for an old size that does not follow the guidelines/formulae applicable for high flotation tyres.

Proposal to

1. amend para 6.1.2. to align the wording to the headers in Annex 5 and to correct the reference to the footnote
2. amend para 6.2.1. to restore corrent references after renumbering made during recent Supplements
3. amend Annex 5, Table 5 to add the value for the Overall diameter (D) in column (*) that applies to tyres marked with classification code “I-3”.
4. amend Annex 5, Table 6, Note 1 to clarify use of the ‘IMP’ and ‘IND’ suffixes for agricultural implements and construction vehicles, respectively.
5. add a footnote to Annex 5, Table 7 is the to introduce the appropriate formulae in the Regulation (instead of via Annex 5)
6. correct cross-references in Annex 7 following the introduction of three new paragraphs in Supplement 15
7. amend Annex 7, Part A to conform with Tire and Rim Association (TRA) specifications for code designated diagonal tyres with speed symbol A8.

In order to have a Regulation on the retreaded tyres with definitions and provisions structured in the same way of those previously introduced in amendments of “new tyres” Regulations, this amendment:

1. indicates that for the purpose of this Regulation “tyres” means “pneumatic tyres” (all text amended accordingly)
2. introduces definitions of:
   • “retreader” copy based on that “manufacturer” in the tyres regulations
   • Brand name", “Trademark”, “Trade description” and “Commercial name” as defined in the tyre regulations
   • Material manufacturer / material supplier
3. takes into account the rounding rules (already approved in the other tyre regulations) for the calculation of width and diameter of the tyres
4. aligns the title and the provisions of the para. 12 related to the names and addresses of Technical Services, Approved Laboratories and administrative Department with their equivalent in the tyres regulations
5. add some information in the certificate to the attention of the Type Approval Authorities for making easier the relationship between this one and the products
6. introduces:
   • In para. 6.4.4.1., the possibility for the material manufacturer or supplier of the pre-cured tread pattern to provide directly to the Type Approval Authority (or Technical Service) all the documents needed to demonstrate the retreaded tyres produced with this pre-cured tread pattern fulfil the requirements of paragraph 7.2. in order to be classified as a “snow tyre for use in severe snow conditions”
   • In para. 7.1.4.2. a new table of tolerances with the objective to properly take into account the requirements for size designations in Annex 5 in addition to what already expressed. The maximum overall width has been taken from the international Tyre Standard ETRTO and Tire and Rim Association.

Proposal to correct references to paragraphs in Regulations Nos. 30 and 54 which have to be updated pursuant to renumbering in the source regulations.

Proposal to

1. exempt cases where the driver has temporarily deactivated the speed limiter from the warning requirement for excess speed in in order to reduce driver distraction
2. introduce throttle control via adjustment of the accelerator pedal position
3. to correct an editorial error in paras. 5.2.5.4.2. and 21.2.5.4.2.

Revised proposal pursuant to GRRF discussions to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls (footnote 12). This proposal (following proposals GRRF/2016/27 as amended by GRRF-82-03 and proposal GRRF-83-31) 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.

Regulation No. 53 currently allows for the activation of the stop lamp by application of the brakes only. As already presented at a session of the Working Party on Lighting and Light-Signalling (GRE) (see ECE/TRANS/WP29/GRE/2015/42), IMMA is proposing to introduce the activation of stop lamps under more conditions than the application of the service brake only, e.g. also by regenerative braking. As noted in the report of seventy-fourth session of GRE, see ECE/TRANS/WP29/GRE/74, para. 30: “the proposal might need to be accompanied by a modification of Regulation No. 78 under GRRF.” Therefore, IMMA has prepared this proposal for Regulation No. 78. A revised corresponding proposal on Regulation No. 53 will also be submitted to the October 2017 session of GRE.

Revised set of amendments to improve and clarify the draft amendment to UN R79 for introduction of provisions for corrective steering and ACSF category A and B1 systems. In particular, the revised document seeks consensus on symbols and interaction between the system and driver, including specifications for notifications related to the status the driver’s hands on the wheel.

Proposal for a harmonized symbol with option for explanatory text to signify a request for and status of the driver’s hands on the steering wheel when the vehicle is in an ACSF mode.

Revised proposal, pursuant to GRRF-83 discussions, to amend the annex on complex electronic systems, in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level.

Proposal to clarify the intent of “a means of detecting that the driver is holding the steering control” by specifying that the vehicle manufacturer would define “holding the steering control” (e.g., one hand, two hands, firmness of grip, etc.) for each vehicle/system under test.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls (footnote 12).

Proposal for amendments to the draft amendment to introduce provisions for corrective steering and category A and B1 automatically commanded steering functions (ACSF) into UN Regulation No. 79 as agreed during the 83rd GRRF session.

Proposal for amendments to the draft amendment to introduce provisions for corrective steering and category A and B1 automatically commanded steering functions (ACSF) into UN Regulation No. 79 as agreed during the 83rd GRRF session, including the proposal to allow for the approval of systems that do not comply with the mandatory use of the color red for the “hands off” steering wheel warning symbol (introduced by this amendment) until 1 April 2020 for consideration by the World Forum.

Addition, based on document GRRF/2016/32, to the package of amendments developed by the informal working group on UN R55 (document GRRF/2017/3). The proposal aims to make clear to Technical Services and Authorities that in cases where no values for the maximum permissible towing vehicle and trailer masses and the maximum permissible static vertical imposed load on the tow device are declared by a vehicle manufacturer or where the declared maximum vertical value is zero, approval shall be refused.

Update on the ad hoc group discussing how to clarify UN R90 with regard to replacement brake components, including discussions on the merits of extending the scope to brake calipers which also relates to discussions on remanufactured components.

Document GRRF-83-08 proposes modifications to document WP.29/2017/10 proposing amendments to UN R79 to enable the approval of corrective steering and category A and B1 automated steering systems (ACSF).

OICA comments and questions regarding the EC proposal to amend the UN R79 annex on complex electronic systems to require auditing of methodologies used to ensure system safety at both concept and system level.

OICA request for confirmation that:

• the provisions for CSF, ACSF A and ACSF B1 will be introduced via a new supplement 06 to the current series of amendments to UN R79;
• the vehicles approved prior to the introduction of the new supplement will not be required to comply with it, even in case of an extension.

Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

Amendment, per GRRF discussions, to remove the proposal to require the use of kPa markings and the related transitional provisions from the broader set of amendments to UN R106 proposed in document GRRF/2017/9.

Comments concerning the clarity and utility of certain provisions in the proposal to amend the annex on complex electronic systems.

Proposed addition, based on document GRRF/2016/32, to the package of amendments developed by the informal working group on UN R55 (document GRRF/2017/3). The proposal aims to make clear to Technical Services and Authorities that in cases where no values for the maximum permissible towing vehicle and trailer masses and the maximum permissible static vertical imposed load on the tow ball are declared by a vehicle manufacturer or where the declared maximum vertical value is zero, approval shall be refused.

Proposal to add tyre and rim dimensions and to add a diameter code ‘d’ of 28.5 (Please note that the “28.5.5” shown in the table is a typo and should be “28.5”).

Proposal to amend the transitional provisions of the formal proposal to update UN R106 (GRRF/2017/9).

European Commission note on the publication of a recent study carried out by the environmental advocacy group Transport & Environment on the performance of indirect TPMS.

Revised proposal for a “Mutual Resolution on dimensions of tyres of certain size designations”.

Revised version of the proposal to include UN R106 tyre dimensions in a Mutual Resolution on tyre sizes. The amendment to the table listing the allowed nominal rim diameters (d) is needed to allow the approval of standardized sizes which exist and are already on the waiting list for type approval.

OICA presentation on its field study to develop data on TPMS performance and comments on the T&E test procedure for evaluating indirect TPMS. In particular, OICA states that the T&E methods did not represent normal use cases or correspond to the intent of UN R141 to address slow diffusion of air that leads to underinflation.

Proposal to extend the scope of UN R131 to include light vehicles in line with priorities in Japan, the EU, and USA with regard to the installation of AEB systems on passenger cars and light trucks.

Proposal to authorize the establishment of an expert group to draft test procedures and performance requirements for M1/N1 with regard to automatic emergency braking, including stationary and moving obstacles, and for pedestrian AEBS.

Proposal to delete passages under paragraph 3.1.15.2. referring to the “prediction of the vehicle deceleration” since no method for doing so is described in the regulation. Moreover, in a self-certification system, the requirement would have to be met for the actual vehicle deceleration. The proposal also substitutes switching between ABS modes for the terms “disable” and “deactivate” for greater clarity. Lastly, the proposal recommends the use of a clearly specified telltale design to signal the ABS operating status rather than to leave this function open to “…any other equivalent unequivocal indication of the disabled antilock brake system state.”

ACSF informal group revisions to the proposal to introduce corrective steering and B1 level (lane-keeping) automatically commanded steering functions provisions into UN R79. The proposal substantially revises the corrective steering test procedure, providing greater clarity over the procedure and requirements, and makes editorial corrections.

Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal to simplify the verification of sufficient movement on the balancer (of the compensator) without having to take measurements underneath the trailer in an potentially unsecured position and to correct the text of Annex 12 (Conditions governing the testing of vehicles equipped with inertia (overrun) braking systems). Intention to provide an objective calculation method as part of setting requirements for permissible “differential travel” or swivel.

Presentation to explain the rational behind the proposal of a new Annex 8 to the R55 introduced in the working document GRRF/2017/03.
