The Informal Working Group on Advanced Emergency Braking System is scheduled for 22 April 2026, starting at 8:00 pm JST, 01:00 pm CET, and 7:00 am EST, finishing at 11:00 pm JST, 04:00 pm CET, and 10:00 am EST. The agenda includes confirmation of terms of reference and leadership in document AEBS2-01-02, proposal of timing in document AEBS2-01-03, planning of work, other business, and listing of action items and next meetings.

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.

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 delete footnote in paragraph 1; add bicycle impact avoidance to scope; amend paragraphs 2.13 and 2.14 regarding road adhesion definitions and Peak Braking Coefficient measurements; amend paragraph 5.4.2.3 requiring two deliberate actions for AEBS deactivation via ESC; renumber footnotes 2 through 9; and insert new paragraphs 5.4.4.1 to 5.4.4.3 to establish special provisions for vehicles equipped with an ADS.

The Informal Working Group on Advanced Emergency Braking System held its first session on 22 April 2026. Focus was confirmed on passenger cars of category M₁ and light vehicles under UN Regulation 152, with heavy vehicles explicitly excluded. The group’s Terms of Reference outline five core tasks. A meeting timeline from April 2026 to September 2028 was proposed, with delivery of an amendments proposal on UN Regulation 152 by September 2028. The co-Chairs called for accidentology data from all Contracting Parties.

Proposal to:

1. Clarify that the PBC values listed in para. 2.14. are minimum values,
2. Align the collision-warning requirements of para. 5.2.1.1. with those for the pedestrian and bicycle scenarios under paras. 5.2.2.1 and 5.2.3.1., and
3. Clarify para. 5.2.1.2. based on feedback from a recent public consultation in Australia.

Proposal to correct errors in the text of the 02 series and its supplements.
