Three options are presented for the document package. Option 1 proposes a Working Document to be submitted by 22 July 2026, with non-agreed items excluded from both memorandum and Informal Document, and a new section created to record non-agreement items. Option 2 proposes a Working Document submitted by 22 July 2026 and an Informal Document drafted by interest parties including Japan for submission during the 95th GRPE in October, titled Interim Guidance for A-LCA to assist practitioners with CFP calculation. Option 3 proposes a Working Document submitted by 22 July 2026 and an Informal Document produced by A-LCA IWG for submission during the 95th GRPE in October, with the same title and aim.
Y-category vehicles are equipped with an Automated Driving System and not designed to carry occupants. They may develop aggressive front structures that could harm passenger cars in accidents. The proposal introduces the Occupant Load Criterium (OLC), derived from velocity-time graphs in crash tests, as a compatibility assessment criterion. OLC multiplied by vehicle mass indicates impact aggressivity. Data from ODB tests show OLC values range from approximately 22 to 35 g across various vehicles. The proposal suggests using a maximum OLC × mass value to prevent excessively aggressive vehicle front structures while keeping current passenger car designs unaffected.
A decision was taken in mid-2025 to start drafting a new regulation collecting relevant safety requirements for Category Y vehicles. UN R127 on pedestrian safety performance could be directly amended to include Y-category vehicles instead of including requirements in a new regulation. TF AVRS agreed to amend UN R127 to include Y-category vehicles. A draft regulation (v4) is available proposing supplement 5 to the 04 series of amendments, including amendment suggestions in scope to determine exemptions for Y-category vehicles based on front structural geometry dimensions rather than R-point criteria.
