Report of the 99th session of the EVE IWG held September 8-9, 2026, covering discussions on UN GTR 21, UN GTR 22, and UN GTR 25. Topics included Japan’s proposal to revise UBE certified value calculations, China’s proposal to incorporate fuel cell vehicles under GTR 21, China’s proposals for vehicle category modifications and minimum performance requirements under GTR 25, Japan’s proposals for measurement requirements under GTR 21, assessment of alternative test methods for GTR 25, and open items across all three GTRs. The group confirmed target dates of March 2028 for GTR 21 and GTR 25 amendments.

Analysis of pedestrian accident data from the GIDAS database (accident years 2005 onwards) comparing day and night situations across crossing and along-carriageway scenarios. Night situations show higher fatality rates than day situations. Data presented for crossing scenarios with and without obstruction, at junctions, and along straight roads, with documented cases from pure car-to-pedestrian constellations.

GB 39901:2025 establishes technical requirements and testing methods for advanced emergency braking systems of vehicles of categories M₁ and N₁, based on UN Regulation No. 152, 02 series of amendments and China’s road accident data. Performance requirements cover collision warning and emergency braking for vehicle, child pedestrian, bicyclist, and powered two-wheeler targets, with car-to-car test speeds extended to 80 km/h for M₁ vehicles. The standard includes general requirements, functional safety, electromagnetic compatibility, robustness, false response testing, and optional simulation testing. Night-time scenarios were tested but not adopted as mandatory requirements pending international consensus on test methods.

Status of the A-LCA informal group activities and schedule for A-LCA Subgroup 2 meetings.

Summary of “Euro NCAP Technical Bulletin CA 101 – Crash Avoidance” for consideration in the context of UN R152.

Draft agenda for the Informal working group on Advanced Emergency Braking System meeting 24–25 September 2026. Welcome and Introduction. Approval of the agenda and previous meeting report (AEBS2-02-03). Confirmation of TOR of this informal working group (document GRVA-24-14/Rev.2). Accidentology: share accident data from other CP. Review of existing regulation, technologies and state of the art. Draft state-of-the-art performance requirements for collision scenarios involving pedestrians at night. Other business. List of action items and next meetings. 4th IWG: 2–4 November 2026 in Tokyo.

Draft amendments concerning lamps under parked conditions presented in a consolidated revision of UN R48.

Terms of reference and rules of procedure for the Task Force on Lamps Under Parked Conditions (TF-LUPC). TF-LUPC shall review the requirements of the current suite of lamps under parked conditions and develop proposals within the framework of UN R48 pertaining to Energy Indicator and Lamp test mode. The task force is open to all GRE participants. Two Co-Chairs (Japan/Netherlands) and a Secretary (OICA) shall manage it. Decisions shall be reached by consensus. STEP 2 aims to present an informal document at GRE’s ninety-fifth session in October 2026 and a formal document at the ninety-sixth session in April 2027 for submission to WP.29 as part of the 10 series of amendments.
