Proposal to improve the wording of the draft amendment on lane-keeping assistance systems, based on document GRRF-79-04.

Comments on the draft amendment to UN R79 addressing automated steering as it stood at the end of the third ACSF informal group session. This document also raises links to rear vision (UN R46), AEBS (UN R131), and park assist systems.

Comments on the draft test procedures as described in the draft text of document ACSF-04-20.

Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

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.

Proposal to amend the consolidated draft amendment to UN R79 to introduce technical requirements for Corrective Steering Functions and Level B1 ACSF under UN R79 (document GRRF/2016/45).

GRVA-1 agreed to reconsider based upon a formal document at GRVA-2 taking into account particularly concerns over the impact of the filtering change on tolerances and interpretation of results.

Proposal to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.

Proposal, based on document GRRF-86-13, to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

Proposal to amend the draft text (GRVA/2019/9) submitted to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:

1. inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
2. sampling rate of at least 100 Hz for dynamic testing,
3. specification of filters and cut-off frequency for determination of lateral acceleration,
4. option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

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.

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

Proposal to require require manufacturers to provide a method for objectively determining the moment of “Risk Mitigation Function” (RMF) initiation to enable assessment of the RMF warning signals and other driver warnings, hazard lights, and indicators in relation to the objectively determined RMF initiation point.

Proposal to require require manufacturers to provide a method for objectively determining the moment of “Risk Mitigation Function” (RMF) initiation to enable assessment of the RMF warning signals and other driver warnings, hazard lights, and indicators in relation to the objectively determined RMF initiation point.

UN R79 mandates verification that appropriate warning signals are provided to the driver based on the timing of a system intervention (e.g., in the case of a Risk Mitigation Function). This proposal aims to clarify the moment of initiation of the signals to facilitate the verification of driver warnings, hazard lights, and other indicators in relation to this objectively determined initiation point. The proposal requires manufacturers to define a clear and accessible method for objectively determining the moment of initiation.

Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.

For the purposes of type approval under any UN Regulation requiring the verification of the timing of a system intervention, manufacturers shall provide to the approval authority or its designated technical service information on the method by which the initiation of any system intervention can be objectively identified and retrieved, including specific flags, status bits, event codes on in-vehicle networks, or visual indications on screens; clear instructions and all necessary tools for the Technical Service to extract, access and interpret the signal identifying the initiation; documented procedures including corresponding data sources, resolution, and timing accuracy appended to the type approval test report; and, where a visual indication displayed on a screen is used, documented latency between the earliest internal point at which the system initiates the function and the moment the visual indication becomes visible on the screen, expressed as a fixed value with associated uncertainty, with the documented latency value used to correct the observed timing of the screen indication appended to the type approval test report.

Proposal to insert a new para. 5.1.12. requiring that manufacturers provide information on the method by which the initiation signal of any system intervention required by the Regulation can be objectively identified and retrieved, including specific flags, status bits, or event codes on in-vehicle networks, and that manufacturers provide clear instructions and all necessary tools for the technical service to extract and interpret the signal, with the procedure for identifying the initiation of the system intervention and corresponding data appended to the test report.
