73. The representative of Australia introduced informal document GRVA-24-04 introducing editorial corrections (as well as GRVA-24-06). GRVA requested the secretariat to distribute it with an official symbol at the next session and requested the secretariat to submit annex V as part of the supplement to the 02 series of amendments to UN Regulation No. 152 (AEBS) for consideration and vote by WP.29 and AC.1 at their June 2026 sessions.

GRVA | Session 25 | 18-22 May

55. During the consultations, the expert from Japan, Co-Chair of the Informal Working Group (IWG) on Advanced Emergency Braking Systems (AEBS), presented the status report of the group (GRVA-25-49). He highlighted the outcome of the group’s first meeting, its proposal for amendments to the terms of reference (GRVA-25-50/Rev.1), and the tentative schedule of future meetings. The expert from Germany presented considerations regarding a Blind Spot Information System for the detection of bicycles and proposed exploring automatic brake intervention in the context of blind-spot-related safety, possibly under UN Regulation No. 151. The experts did not reach consensus and agreed to continue discussions in September 2026. The expert from Australia introduced ECE/TRANS/WP.29/GRVA/2026/21, aimed at addressing ambiguities in the 02 series of amendments to UN Regulation No. 152 and its supplements, as well as ECE/TRANS/WP.29/GRVA/2026/22, containing editorial amendments.

56. GRVA endorsed the status report of the IWG on AEBS (GRVA-25-49).

57. GRVA adopted the revised terms of reference for the IWG on AEBS (GRVA-25-50/Rev.1 reproduced in Annex III).

58. GRVA decided to defer ECE/TRANS/WP.29/GRVA/2026/21 and GRVA-25-36 to the IWG on AEBS.

59. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/22 and requested the secretariat to submit it to WP.29 and AC.1 as draft supplements to the original version and 01 series of amendments to UN Regulation No. 152 for consideration and vote in November 2026.

60. GRVA agreed to resume discussion of GRVA-25-08 in September 2026.
