Proposal to insert new paragraphs 3.1.1, 3.1.2, 3.2.2, and 4.6 to 4.6.6 in UN Regulation No. 157. The manufacturer shall provide approval authorities with a single point of contact, expected granting approval authority, and brief details of the ALKS and its ODD prior to application for approval. The granting approval authority shall inform receiving approval authorities of territories where ALKS can be active and provide specified information at least 30 days before granting approval. Receiving approval authorities may provide comments within 30 days, with disputes resolved per the 1958 Agreement. These provisions apply to both the original version and the 01 series of amendments, referencing WP.29/343.

Proposal to amend Annex 4, paragraph 3.5.4, to require the manufacturer to report critical incidents to the granting type-approval authority, and to insert new paragraph 3.5.4.1 requiring the type approval authority to upload information received from the manufacturer in English language to the secure internet database “DETA” without undue delay but no later than 14 days after receipt. A new Annex 7 provides guidance for data exchange via DETA in accordance with paragraph 3.5.4.1.

Proposal to amend UN R171 to modify paragraphs 5.5.4.2.8.2., 5.3.7.2.4.2., 5.3.7.2.6.1., 6.4.2., 7.2.3.1., 14.2., and Annexes 3 and 4. The amendments include clarifications regarding driver engagement determination, system boundary conditions, automatic acceleration in non-highway environments, system-initiated manoeuvres tracking, production discontinuation, documentation retention periods, supplier safety management arrangements, and test scenario specifications for bicycle and cyclist targets.

Consolidated proposal to clarify provisions in the original version of the Regulation. See GRVA/2026/16 for the proposed amendments.

Proposal with the amendments to UN R171 presented in the consolidated version in GRVA/2026/15. Modifications include: inserting new introduction paragraph 17 establishing the regulation on current technology with continuous review based on data; amending paragraphs on system boundaries, driver disengagement detection, manoeuvre initiation, and Risk Mitigation Function; clarifying driver state monitoring and visual engagement assessment; updating terminology for powertrain; deleting duplicate definitions; adding processes for safety management during operation phase; inserting definition of “Evidence”; clarifying base and extended test requirements; and updating language from “cyclist” to “bicycle” in test scenarios.

Consolidated version based on WP.29/2025/7 as amended by WP.29-195-05, WP.29/2025/144, GRVA-24-18, and GRVA-24-19. See GRVA/2026/18 for the proposed amendments.

Proposal to clarify UN R171 on Driver Control Assistance Systems (DCAS). The modifications include clarifications to definitions, adding “Highway-like road” definition; clarifications to system boundary detection, manoeuvre initiation, and driver disengagement requirements; amendments permitting withholding of hands-on requests on highway-like roads up to 130 km/h; clarifications on Risk Mitigation Function terminology; amendments allowing alternative strategies for lower-speed lane changes; addition of operational phase safety management processes; and clarifications on testing requirements and non-rule-based algorithm repeatability.

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 of 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 introduce clarifications and references to lane markings, including ELKS effectiveness not be adversely affected by magnetic or electrical fields per UN R10 05 series, vehicle operating instructions include situations where ELKS is automatically deactivated, referencing lane markings in UN R130 01 series amendments in paragraphs 6.5.2, 6.6.2.1, 7.2.1, and 8.2.1, amending tyre pressure and warning threshold test procedures, and inserting transitional provisions (May 2027-May 2029).

Proposal to amend paragraph 2.14. to clarify that road surface friction coefficient of at least the specified Peak Braking Coefficient represents minimum values; amend paragraph 5.2.1.1. to align collision warning requirements with pedestrian and bicycle scenarios, requiring collision warning no later than 0.8 seconds before emergency braking or at braking start if anticipation time is insufficient; amend paragraph 5.2.1.2. to clarify that emergency braking involves a braking demand of at least 5.0 m/s² to the service braking system, permitting higher demands during collision warning for short durations.

Proposal to amend paragraph 5.4.2.3. of the 01 series of amendments and the original version to UN R152 to require at least two deliberate actions by the driver where automatic deactivation of the AEBS function is a consequence of the driver manually switching off the ESC function of the vehicle. Footnotes 2 to 8 in the 01 series are renumbered to accurately reference correct footnotes. This revision addresses GRVA-24-04.
