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.

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.

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 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.
