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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.
