Proposal to adapt UN R79 in line with the proposed addition of camera-monitor systems to UN R46 (indirect vision). UN R79 refers to external mirrors in test procedures involving the vehicle turning circle. This proposal replaces the reference to mirrors with a broader reference to “indirect vision devices” that includes CMS.

Comments on document ACSF-03-03. In particular, the document raises the question of whether the proposed amendments should address software validation, the eventual use of external data from infrastructure or V2V sources, and responses to system/driver response failures.

Proposal to define and require countermeasures to ensure that a driver remains available to assume control of a vehicle from an automated lane-keeping/steering system as conditions warrant. This document proposes definitions for a “driver attention recognition [system/function]” and/or a “driver attention confirmation [system/function]”.

Proposals to clarify that references to “other road users” includes pedestrians and large animals and, with respect to ensuring the driver’s availability to assume control of the vehicle, a time frequency limit for driver monitoring systems based upon the time required to travel a distance of 1500 m with an upper limit of 180 seconds (i.e., the time required to travel 1500 m at 30 km/h).

Proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.

The Netherlands and Sweden note strongly urging consideration of system safety and software assessment issues before proceeding with approval procedures for Category B2 and/or E ACSF, including a discussion of the role, if any, of ISO 26262 under Annex 6.

Comments concerning the clarity and utility of certain provisions in the proposal to amend the annex on complex electronic systems.

Netherlands proposal for incorporating the UN Regulation on software systems (under development within the Cybersecurity/OTA task force) into UN Regulation No. 79 on steering. UN R79 is being updated to address the approval of automated steering functions. This document is a version of the regulation with a new paragraph 5.1.11.: “The performance of the steering system shall not be adversely affected by the software present in the system. This shall be demonstrated by compliance with the technical requirements and transitional provisions of Regulation No. X[Software Regulations], series of amendments or any later series of amendments.”

Proposal to specify a light general-purpose street motorcycle without fairings or windscreens having an engine capacity between 400 cm³ and 600 cm³ as the approaching vehicle in the testing of automated lane-change systems under UN R79.

Proposal to delineate the scope of UN R79 vis-à-vis the draft new UN Regulation on Driver Control Assistance Systems (DCAS).

Document GRVA-17-49 from the September 2023 GRVA session.

Copy of document GRVA-17-49.

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

Proposal to ensure that vehicles exhibiting functionality meeting the definition of ACSF-B2 or -E are required to comply with the 01 series of R171 (or later). The 01 series added the necessary technical requirements to ensure the safety of features that allow ‘hands-free’ operation or perform system-initiated manoeuvres.
