This document summarises the reviews conducted by the GR working parties on the fitness for ADS of UN Regulations and GTR for application to ADS vehicles. This document represents the current opinions of the experts at the time of submission, and the recommendations contained inside may evolve significantly during the next steps of the process of reviewing and amending Regulations.

Proposal to clarify the requirements related to the Type IIA test.

Proposal to extend the scope of UN R155 to include all vehicles of Category L.

Proposal to align the UN R155 Interpretation Document with the proposal to extend the scope of UN R155 to Category L vehicles.

Proposal to differentiate between the scope of UN R79 and the proposed UN Regulation on Driver Control Assistance Systems (DCAS).

Proposal to align the regulation 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 the regulation 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. The proposal would also amend the requirements for the safety of electronic systems.

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

Proposal to clarify the provisions concerning the conditions for automatic re-instatement of the system at the “initiation of each engine start / run cycle”.

Proposal to clarify the conditions for automatic re-instatement of the system at the “initiation of each engine start / run cycle”.

Proposal to clarify provisions concerning the conditions for automatic re-instatement of the system at the “initiation of each engine start / run cycle”.

Proposal to clarify the conditions for automatic re-instatement of the system at the “initiation of each engine start / run cycle”.

Proposal on terminology about the status of the system following an “engine start / run cycle”.

Proposal for terminology about the status of the system following an “engine start / run cycle”.

Proposal to improve terminology concerning the status of the ACSF system following an “engine start / run cycle”.

Proposal to improve terminology concerning the status of the AEBS following an “engine start/run cycle”.

Proposal to improve terminology concerning the status of the AEBS following an "engine start / run cycle”.

Proposal to improve terminology concerning the status of the AEBS following an “engine start / run cycle”.

Proposal to improve terminology concerning the status of the AEBS following an “engine start / run cycle”.

Proposal to improve terminology concerning the status of the AEBS following an “engine start / run cycle”.

Proposal to improve terminology concerning the status of the system following an “engine start / run cycle”.

Proposal to ensure that vehicles exhibiting functionality meeting the definition of ACSF-B2 or -E are required to comply with the correct series of R171.

Proposal improve consistency in the bedding/burnishing procedure and to align the Communication Form with that of other UN Regulations.

Proposal to align UN R130 with the harmonised wording approved by WP.29 with regard to conditions for automatic reinstatement of a system at the “initiation of each engine start/run cycle”.

Proposals to resolve issues with accepting the approval of M₂, M₃ and N₂ vehicles to Regulation No. 152.

Proposal based on informal document GRVA-25-43 to amend Annex 4, para. 3.5.1. to require the manufacturer to demonstrate to the Type Approval Authority at least every three years that the safety management system continues to comply with requirements for software and hardware employed in the system. This amendment applies the same principle regarding Safety Management System compliance as specified in UN Regulation No. 171 on Driver Control Assistance Systems.

Proposal to amend UN R155 by inserting new para. 5.1.3.(e) establishing that the Certificate of Compliance for the Cyber Security Management System shall not be issued by a different Approval Authority than the one granting type approval, and amend UN R156 by inserting new para. 5.4. establishing that Approval Authorities shall not grant type approval if the Certificate of Compliance for the Software Update Management System has not been issued by the same Approval Authority granting type approval. Justification includes ensuring holistic cybersecurity assessment, clarifying reporting obligations under para. 7.2.2.2.(g), addressing unharmonized mutual recognition of management system certificates, maintaining consistency between regulations, and upholding the fundamental principle that approval authorities retain responsibility for all aspects of type approval.

Proposal to amend para. 3.5.1. in Annex 3 to require the manufacturer to demonstrate to the Type Approval Authority at least every three years that the safety management system continues to comply with requirements for software and hardware employed in the system to manage safety and continued compliance throughout the product lifecycle. This amendment resolves outstanding issues in the 01 series of amendments to UN Regulation No. 171.

Proposal to amend Annex 8, para. 3.4.1. to require that the strategy chosen shall not prejudice safe operation of the system due to failures with other systems involved in achieving the function of the system, and amend Annex 8, para. 3.4.4. to require that analysis of system behaviour on fault occurrence includes faults with other systems involved in achieving the function of the system, and to correct ‘safetys’ to ‘safety’. The proposal addresses a collision where tyre failure resulted in unsafe ABS activation. Although the 02 series clarified ABS as part of electronic control systems assessment, it does not explicitly state what is covered, potentially missing relevant faults or failures influencing system function. The additions ensure all relevant faults or failures are accounted for in manufacturers’ safety concept and analysis.

Copy of the proposal to establish a compendium of the test tools used in Global Technical Regulations (and UN Regulations) to permit such regulations test tools according to a single source rather than having to revise each regulation with each change in tool specifications.
