Proposal for a minor editorial correction to the text. Paragraph 4.8. should read “Annex 2 to this Regulation gives an example of approval marks.” The current text refers to “examples” where there is only one provided.

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.

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.

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.

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)

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.

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 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.

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

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.

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

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

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 to add a tyre example regarding approval numbering in order to account for requirements under certain tyre regulations where the number of digits of some sections in the approval number may be amended.

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

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.

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.

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 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.
