List of decisions taken during the GRVA session in Troy, Michigan (USA) for ratification during the formal GRVA session on 25 June 2024 in Geneva.

Proposal to clarify EMC requirements: "The effectiveness of the system shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by fulfilling the technical requirements and respecting the transitional provisions of 07 or later series of amendments to UN Regulation No. 10.” This proposal supersedes document GRVA/2024/3.

Proposal to clarify requirements in the scope requesting for reciprocal recognition with United Nations Regulation No. 131 (Advanced
Emergency Braking Systems (AEBS).

Proposal to clarify requirements in the scope requesting for reciprocal recognition with UN Regulation No. 152 (Advanced Emergency Braking System (AEBS) for M1 and N1 vehicles).

Proposal to enable use of virtual testing methodology as alternative methodology to the physical tests.

Proposal to introduce provisions for using virtual testing as an alternative to physical tests.

Proposal to introduce a mapping of requirements and references to ISO 24089:2023 (“Road vehicles–Software update engineering”) where such referencing could aid the understanding and/or implementation of UN R156 requirements.

Proposal to introduce provisions for using virtual testing as an alternative to physical tests in UN R152.

Proposal to introduce provisions for using virtual testing as an alternative to physical tests in UN R152.

Proposal to restore a footnote omitted during the preparation of the document.

Proposal to clarify the need to apply, when relevant, the Type II test as required by Annex 4 under paragraph 1.8.2.5 (b) in Annex 15 for alternative brake lining purposes.

Consolidated amendment of the ADS guidelines and recommendations, integrating the proposals in GRVA-19-12 and GRVA-19-13.

Proposal to allow periodical technical inspection testing and verification of heavy-duty braking systems without burdening the vehicle
owners/managers.

Proposal to clarify provisions concerning the type-IIA test and the test mass of vehicles authorized to tow trailer(s).

Proposal to amend the proposal to permit the use of a positive lock type system as an alternative to a friction type parking braking system.

Proposal for amendments to the proposal to permit the use of a positive lock type system as an alternative to a friction type parking brake system.

Proposal to facilitate a consistent approach across all Contracting Parties for Emergency Lane Keeping Systems (ELKS) covering vehicles of category M1 and N1. Currently the European Union mandates ELKS through EU Regulation 2021/646. This document proposes to align UN R130 with the EU regulation.

Proposal to clarify the provisions for full power steering systems such as steer by wire systems (based on discussions held under the EBSIG interest group addressing electro-mechanical braking systems under UN R13 and 13-H).

Proposal to introduce specific deceleration requirements for the Speed Electronically Power Assisted Cycles belonging to the Category L in UN R78.

Proposal to align UN R79 and UN R157 with UN R152 (AEBS for M1 and N1) regarding the conditions for automatic re-instatement of a system at the “initiation of each engine start / run cycle”.

Proposal to clarify provisions concerning the type-IIA test and the test mass of vehicles authorized to tow trailer(s) (responding to the proposal made in document GRVA/2024/7).

Proposal from the ADAS task force for editorial improvements and corrections to the new UN Regulation on the approval of Driver-Control Assistance Systems.

Proposal to update the regulation in line with technical advances and the emergence of a new type of braking system that employs stored electrical energy for both the control transmission and the energy transmission.

Proposal to align UN R13-H with technical advances and the emergence of a new type of braking system that employs stored electrical energy for both the control transmission and the energy transmission.

Proposal to facilitate a consistent approach across all Contracting Parties for Emergency Lane Keeping Systems (ELKS) covering vehicles of category M₁ and N₁.

Proposal to amend RE3 to align with UN R156 and other regulation requirements for use of the RxSWIN identification number.

Proposal to allow for the use of virtual testing as an alternative to physical tests.

Proposal to clarify the type-approval process concerning the reciprocal recognition of approvals to UN R131 and UN R152 (i.e., the conditions under which Contracting Parties applying both regulations are required to accept approvals under either regulation as equally valid for vehicles of category M₂ and for vehicles of category M₃/N₂ with a maximum weight below or equal to 8t and equipped with hydraulic braking).

Proposal to permit the use of a positive lock type system as an alternative to a friction type parking brake system.
