This document was produced during an informal meeting (on 23 September 2020) of interested experts who reviewed the ALKS-related documents presented at GRVA on 24 September 2020.

Proposal including amendments submitted in GRVA-07-05 and superseding document GRVA-07-47.

Presentation concerning requirements related to electric regenerative endurance braking systems.

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.

Supporting information on the proposal to allow for parking brake warning device actuation after an electric control transmission system produces a stable parked state.

Proposal to ensure the continuity of the ASTM Method E1337 for the measurement of the Peak Braking Coefficient (PBC) by introducing a reference to the new American Society for Testing and Materials (ASTM) Standard Reference Test Tyre F2493.
