Revised and updated version of the GRVA presentation (GRVA-08-23).

Proposal for amendments to the proposal to introduce provisions for electro-mechanical braking systems (submitted to WP.29 as document WP.29/2021/12).

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 address difficulty in Conformity of Production (CoP) routine obligations caused by unavailability of specifically prescribed hardware.

Proposal to clarify that DC voltage thresholds should be applied to pulsating DC voltages (also known as “switched” DC) that alternate voltages without a change in polarity.

Comments regarding "react to road users/traffic signs as good as a human driver”, “detectable collision” and presentation from France concerning vehicle configuration vs ADS safety.

OICA/CLEPA Input to the TF ADAS special session dedicated to RMF.

Proposal to clarify specific conditions concerning the interpretation of an AC voltage (rms).

Proposal for an alternative method to the actuation of the remote-control device for the use of RCP based on document GRVA-08-28.

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.

CLEPA draft as revised during the subgroup session. Marked up version with revisions also available.

Proposal to clarify the definition of “specific voltage condition” via a Supplement 1 to the 04 series of amendments to UN R94, Supplement 2 to the 05 series of amendments to UN R95, Supplement 2 to the 02 series of amendments to UN R137, and Supplement 2 to the original series of amendments to UN R153.

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).

ECE/TRANS/WP.29/GRVA/2021/15 was prepared by the expert from the European Association of Automotive Suppliers (CLEPA) to resolve the problem of fulfilling increasingly difficult Conformity of Production (CoP) routine obligations caused by unavailability of the specifically prescribed hardware.

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.

Document as revised during the 15th TPMSTI task force session.

Draft proposal to exempt certain vehicle configurations from the scope of UN R151.

Submitted by the ADS safety topics and DDT workstream pilot.

Submitted by the ADS safety topics and DDT workstream pilot.

Proposal to amend the provisions of ACSF of Category C with the main aim to include a truck – trailer data transmission.

Version 1.8.

Version 2.1.

Proposal to resolve problems with installation of stronger spring brake actuators in trailers to realize higher deceleration in the case of emergency braking caused by a cut of the supply line between towing vehicle and trailer.

Proposal to clarify the continuous support provided by the Automatically Commanded Steering Function of Category B1 after reaching its boundary conditions.

Proposal to amend the current support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for assessing the external dimensions of an ECRS.

Proposal to amend the current support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for assessing the external dimensions of an Enhanced Child Restraint System (ECRS).

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.

Proposal by the expert from the European Association of Automotive Suppliers (CLEPA) to include provisions for the type approval of Electro-Mechanical Braking (EMB) systems as state-of-the-art braking systems. This document supersedes ECE/TRANS/WP.29/GRVA/2021/24.

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 resolve problems with installation of stronger spring brake actuators in trailers to realize higher deceleration in the case of emergency braking caused by a cut of the supply line between towing vehicle and trailer.

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.
