Proposed changes to the draft amendment to UN R79 on automatically commanded steering functions.

UK input to confirm basic understanding of the proposed categories of corrective steering and automatically commanded steering functions and to propose requirements under each category.

Proposals to delineate the difference between corrective steering (driver assistance) and automatically commanded steering (automated driving) functions, clarify the definition of Complex Electronic Systems, require system deactivation when sensors are blocked, and to require indication of the level/version of software in use.

Proposal for a harmonized symbol with option for explanatory text to signify a request for and status of the driver’s hands on the steering wheel when the vehicle is in an ACSF mode.

Results of the April Amsterdam meeting to understand boundary conditions for rearward detection radar systems (essential to Category C lane-change ACSF).

Category G vehicles (defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3)) have specific characteristics that enable them to achieve traction on, and to traverse over, off-road terrain that would defeat and/or damage conventional road vehicles. In some situations, it would be safer for the driver to be able to manoeuvre the vehicle from outside. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate in this environment and the off-road location is confirmed throughout the whole period that the function is in use.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems, defined as driver-actuated systems on off-road vehicles used for navigating exceptionally difficult terrain. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate off-road and the off-road location is confirmed throughout the whole period that the function is in use.

This document presents changes agreed by an informal group of experts reviewing the content of Annex 6 since the 84th session of GRRF. The proposal aims to clarify the purpose of Annex 6 and ensure its suitability when used in the assessment of steering systems featuring advances in automation (i.e., ACSF).

Proposal to introduce provisions in UN Regulation No. 79 (Steering equipment) for the approval of Remote Control Manoeuvring (RCM) systems.

This document presents the output of an informal group of experts reviewing the content of Annex 6 on complex electronic systems. Its purpose is to update Annex 6 to ensure its suitability when used in the assessment of steering systems featuring advances in automation.

Proposal to clarify that M₁ and N₁ not approved as category G may be equipped with Remote Controlled Maneuvering systems provided they meet the requirements to be classified as such.

Proposal to clarify the assessments to be conducted by a technical service for complex electronic systems, particularly with regard to advanced driver assistance systems. The proposal includes a new definition to ensure the assessment includes system response to changes in the ambient and/or operating conditions, provisions to ensure that any disabled functions intended for use on a production vehicle are declared and assessed, and a footnote to clarify that the assessment must be reviewed and signed by the same type approval authority as the one responsible for issuing the approval to UN R79.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems.

Proposal to

1. correct numbering of paragraph 2.3.4.18.
2. limit the initial scope to M₁ and N₁ vehicles
3. further modify the numbering to clarify that remote-controlled maneuvering (RCM) is not a form of ACSF
4. clarify that all RCM are subject to the requirements of the Electronics Annex (Annex 6 to UN R79).

Proposal to ensure that the safety approach for complex electronics of remote controlled maneuvering addresses malfunctions, non-fault errors, and misuse.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems.

Proposal to update and clarify Annex 6 on requirements for documentation, fault strategy and verification of the safety of electronic systems and complex electronic vehicle control systems related to vehicle steering. The assessment particularly addresses driver assistance and automated steering.

Updated remote-controlled maneuvering proposal with editorial Improvements, clarification that the actuator of the function is to be included as part of the assessment along with the hardware and software on the vehicle, and to add requirements on the security of the connection between the remote-control device and the vehicle.

Proposal to allow ACSF-B lateral acceleration above the maximum limit value in cases where the lane position cannot be maintained by the vehicle (for example, on a tightening curve).

Comments on the proposal to allow continuous movement of the driver as an alternative to the continuous actuation of the remote-control device as a means to assure driver attentiveness during remote-controlled parking.

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

Copy of document GRVA-17-49.

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

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

Updated during the FADS session discussions.

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

Includes FADS session discussion.

Proposal to update the text in line with the establishment of UN R171 on DCAS.

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 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 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.

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 from the ADAS task force to extend the provisions clarifying the scope between this Regulation and UN R171 for the ACSF categories B1, B2, C, D, E to ACSF category A.
