Proposal to amend para. 5.3.3.2. to clarify that steering shall remain possible with performance laid down in para. 6. for the intact steering system in case of control transmission failure, amend para. 6.1.1. to specify that tests shall be conducted on a level surface affording good adhesion at ambient temperature between 0°C and 45°C, with provisions for deviating conditions at manufacturer request with Technical Service agreement, and insert new para. 6.2.5.1.1. to permit vehicle manufacturers to request at least 10 “figure of eight” manoeuvres with 40 m diameter loops at 10 km/h speed prior to measurement of steering efforts with steering equipment failure.

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 amend para. 5.3.3.2. to correct a referencing error by replacing the reference to para. 5.1.4. with a reference to para. 5.3.1.1., which directly relates to mechanical parts of the steering transmission, thereby removing possible uncertainty or the need to liaise with the designated technical service or approval authority to confirm interpretation of the current text.

Proposal to develop UN GTR for both assisted and automated parking. The document presents parking product classifications in China, including assisted parking (park-in/park-out, cruising capability, remote-control variants) and automated parking systems. Current UN Regulations lack specific technical requirements, test methods, and test scenarios for parking functions. China is developing national standards GB for parking combined driver assistance systems and automated parking systems, with approval expected by end of 2026 and early 2027 respectively. The proposal suggests establishing a Task Force to study applicability of current UN Regulations to parking products, then determining whether to establish an IWG or formulate new regulations.

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.

Proposal to insert provisions on software identification and software updates into UN R13, UN R13-H, UN R79, UN R89, UN R130, UN R131, UN R152, UN R155, UN R156, UN R157, UN R171, UN R175, and UN R178 by adding definitions referencing Consolidated Resolution R.E.3 Annex 7, requiring manufacturers to provide Technical Services with information on hardware and software influencing performance, permitting vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles, clarifying that production discontinuation does not apply when manufacturers seek approval extensions for software updates of registered vehicles, and amending communication forms to include software identification numbers and related information.

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.

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.

Since the 24th (January 2026) GRVA session, the ADAS task force held an online session on 3 March 2026. A 02 series of amendments to UN R171 (GRVA-24-17/Rev.2) was approved and submitted to WP.29 as WP.29/2026/86. Draft supplements and consolidated and extracted versions for 00 and 01 series were prepared (GRVA-24-18-A, GRVA-24-19-A, GRVA-24-18-B, GRVA-24-19-B). For the 25th GRVA session, editorial modifications and consolidated and extracted versions were submitted (GRVA/2026/14, GRVA/2026/15, GRVA/2026/16, GRVA/2026/17, GRVA/2026/18). The task force seeks guidance on provisions for DCAS use on highway-like roads and feedback on existing provisions following practical implementation of UN R171. The ADAS task force will be maintained with a break in activities pending stakeholder inputs and concrete proposals.

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.

Proposal to amend paragraph 4.4.3. to add letter “X” preceding the approval number when ACSF of Category A, B1 or C have been exempted from technical requirements or when the steering system exhibits functionality defined as ACSF of Category B2, D or E; amend paragraph 5.6.1. to add provisions for vehicles equipped with ACSF of Category A unless equipped with a DCAS complying with UN R171; and amend paragraph 5.6.1.2.9. regarding deactivation of RCP systems based on detection of driver position and movement through a simple and obvious action.

Proposal to amend paragraph 4.4.3. to add a letter “X” preceding the approval number when ACSF of Category A, B1 or C are exempted from technical requirements or when the steering system exhibits ACSF of Category B2, D or E functionality, to require vehicles equipped with ACSF of Category A to fulfil requirements unless equipped with a DCAS complying with UN Regulation No. 171, and to require deactivation of RCP systems based on driver position detection through a simple and obvious action.

Proposal to amend paragraph 5.6.1.2.9. of UN R79 to require that for RCP systems based on detection of driver position and movement, the deactivation referred to in paragraph 5.6.1.1.3. shall be through a simple and obvious action that will be recognised by the system.

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 correct paragraph 5.6.1.2.9. of Supplement 1 to the 04 series of UN R79, Supplement 6 to the 03 series of UN R79, and Supplement 3 to the 02 series of UN R79. For RCP systems based on detection of driver position and movement, the deactivation referred to in paragraph 5.6.1.1.3. shall be through a simple and obvious action that will be recognised by the system.

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.
