|
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 for a Supplement 17 to the 03 series and a Supplement 12 to the 04 series to insert new Paragraph 6.2.5.1.1. into UN R79. If requested by the vehicle manufacturer, the vehicle may undergo up to ten figure eight manoeuvres, where each loop of the figure is 40m diameter at 10km/h speed with intact steering equipment, before the measurement of steering efforts with a failure in the steering equipment. This amendment aims to clarify pre-test conditions for measuring steering effort under a failure condition and to stabilize power steering oil temperature, particularly for vehicles of category N3 and M3. |

Proposal to insert new sub-paragraph 5.6.1.1.4.1 establishing that requirements of paragraph 5.6.1.1.4 shall not apply to ACSF Category A functions provided they are intended solely to support low-speed vehicle controllability manoeuvres in off-road environments, operate only until 5km/h with 1km/h tolerance, require deliberate driver activation, require driver presence in driver’s seat with fastened safety belt, and allow driver to retain control and override or deactivate the system at any time. |

| UN R79: Maximum RCP Operating range |
| Reference Number: GRVA-25-13 |
|
Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79. |

|
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 for a Supplement 17 to the 03 series and a Supplement 12 to the 04 series to insert new Paragraph 6.2.5.1.1. into UN R79. If requested by the vehicle manufacturer, the vehicle may undergo up to ten figure eight manoeuvres, where each loop of the figure is 40m diameter at 10km/h speed with intact steering equipment, before the measurement of steering efforts with a failure in the steering equipment. This amendment aims to clarify pre-test conditions for measuring steering effort under a failure condition and to stabilize power steering oil temperature, particularly for vehicles of category N3 and M3. |

Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79. |

Supporting presentation on the proposal to insert a new sub-paragraph 5.6.1.1.4.1 to exempt ACSF Category A functions intended solely to support low-speed vehicle controllability manoeuvres in off-road environments from the obstacle detection requirements of paragraph 5.6.1.1.4, provided the function operates only until 5 km/h with 1 km/h tolerance, is activated deliberately by the driver in off-road environments only, requires the driver to be in the driver’s seat with safety belt fastened, and allows the driver to retain control and override or deactivate the system at any time. |

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 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. |

| Reference Number: GRVA-24-11 |
|
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 for a Supplement 17 to the 03 series and a Supplement 12 to the 04 series to insert new Paragraph 6.2.5.1.1. into UN R79. If requested by the vehicle manufacturer, the vehicle may undergo up to ten figure eight manoeuvres, where each loop of the figure is 40m diameter at 10km/h speed with intact steering equipment, before the measurement of steering efforts with a failure in the steering equipment. This amendment aims to clarify pre-test conditions for measuring steering effort under a failure condition and to stabilize power steering oil temperature, particularly for vehicles of category N3 and M3. |

Proposal to insert new sub-paragraph 5.6.1.1.4.1 establishing that requirements of paragraph 5.6.1.1.4 shall not apply to ACSF Category A functions provided they are intended solely to support low-speed vehicle controllability manoeuvres in off-road environments, operate only until 5km/h with 1km/h tolerance, require deliberate driver activation, require driver presence in driver’s seat with fastened safety belt, and allow driver to retain control and override or deactivate the system at any time. |

| UN R79: Maximum RCP Operating range |
| Reference Number: GRVA-25-13 |
|
Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79. |
