Proposal to improve the consistency of the text with regard to “motive power” references.

Counter-proposal from OICA to a German proposal (GRSP/2019/18) to address vehicles with active suspensions and amend the definitions and specifications and Annex 1, Part 1. This document supersedes previous OICA submissions GRSP-67-07 and GRSP-68-18.

Revised proposal to allow alternative test methods for heavy duty vehicles in order to improve applicability of the requirements to vehicles of categories M₂, M₃, N₂ and N₃, superseding GRSP/2021/12.

Proposal by the experts from OICA to add some further suggestions to GRSP-70-12

Revised proposal prepared by the secretariat pursuant to discussion of GRSP/2021/28, proposing to align UN R127 with provisions set out in the revised General Safety Regulation (EU) 2019/2144 that will apply in the European Union in accordance with the proposed transitional provisions. The proposal also covers a specific provision on optional monitoring of headform contact with A-pillars, windscreen header and cowl and proposes inconsequential adaptations and clarifications to the existing requirements.

Discussion on ECE/TRANS/WP .29/GRSP/2021/19

Expands the scope and covers: M1 with a maximum permissible mass not exceeding 3,500 kg; M1 with a maximum permissible mass exceeding 3,500 kg and a low “R” point and N1.

Proposes alternative test methods for heavy duty vehicles in order to improve applicability of the requirements to vehicles of categories M2, M3, N2 and N3.

Argument for revising the PBC values used in the regulation based on technological progress in tyres and impact on road-friction parameters.

Proposal to amend the peak braking coefficient and related test method provisions.

Given that UN R94, 95 and 137 refer only to vehicle categories M₁ and N_{1</, the proposal would add references to UN R29 and 66 to specify an impact severity level for heavier vehicle categories for data retrieval performance limits.}

Comments on the proposal from Germany to require electrically operated parking brake systems to automatically activate when the driver leaves the vehicle cabin and/or the motor is stopped.

Proposal of improvements to the draft text regarding limitations on continued ACSF support after exceeding the system boundary conditions.

Proposal to clarify AEBS restart, including that an automatic engine restart (stop/start systems) does not require a reactivation of the AEBS, to allow for electromagnetic compatibility demonstration via the 06 series of amendments to UN R10, to move provisions for Indication of an ongoing initialization from the section on failure indications to a separate paragraph, and to make an editorial correction.

Proposal to amend provisions related to the AEBS peak braking coefficient.

Proposal to align the wording with regard to “dry road affording good adhesion” across the series to avoid confusion with use of “dry road” under different contexts by other regulations.

Proposal to clarify the text with regard to transitional provisions and extension of approvals.

Proposal for an alternative to the actuation of the remote control device for the use of Remote-Controlled Parking functions.

This proposal seeks to permit manoeuvring assistance in certain low speed driving situations. The proposal is identical to that briefly presented as document GRVA-07-24 at the seventh session of GRVA (September 2020).

Proposal for amendments to the proposal to allow up to seven seconds between the start of the lane change procedure and the start of the lane change manoeuvre.

Proposal to clarify the existing text on continued support of an Automatically Commanded Steering Function of Category B1 if the boundary conditions are exceeded. It proposes to clarify that under certain circumstances, e.g. if there are no lane markings present or if the vehicle has already drifted substantially out of the lane such that the lane may no longer be recognized, a continuation of support may no longer be possible or reasonable.

Input on the proposal from Germany to require electrically operated parking brake systems to automatically activate when the driver leaves the vehicle cabin and/or the motor is stopped.

Proposal to amend Supplement 3 to the 01 series of amendments to clarify the conditions under which the braking signal for vehicles equipped with automatically commanded braking and/or regenerative braking is to be generated.

Proposal to allow the parking brake warning device to be actuated only once the electric transmission of the parking brake is in a stable state securing the park brake application.

The proposal is to ensure that the adhesion of the road surface will not limit AEBS performance during test.

Proposes to align the wording with regard to “dry road affording good adhesion” also in the 02 series of amendments with the purpose of avoiding confusion with other regulations that might refer to a “dry road” in a different context

Proposal to clarify the different interpretation from Authorities and Technical Services on how the requirements of paragraph 5.2.22.2. are to be understood with regard to the conditions under which the signal is still to be generated.

Proposal to clarify provisions regarding the actuation of the parking brake warning device to cover the case of electric control transmission systems where there may be a transition between parked (applied) and un-parked (released) braking states. The aim is to reduce risks of user confusion by specifying that the warning device would be actuated only after the parking brake has achieved a stable applied state.
