Minutes of the 26th meeting of GRSP TF on AVRS held on Tuesday 22nd of May 2026 online. The agenda and previous minutes were approved. Status reports were received from other groups, with a closing meeting on ADS fitness expected in June. GRSP reviewed consistency of ADS fitness work and UN Regulation 137 sensor updates. EC presented updates on UN Regulation N₁Y and UN Regulation 127 pedestrian protection. OICA raised discussion on frontal test procedures in Annex 3 referencing UN Regulation No. 94 for vehicles with maximum mass not exceeding 2,500 kg and UN Regulation No. 137 for vehicles with maximum mass exceeding 2,500 kg and not exceeding 3,500 kg. No comments were received on passive safety requirements for ADS steering systems. Future meetings are scheduled for 1–5 June, 1st July, 4th September, 5th October, 27th November, 1st December, and 7–11 December.

A new UN Regulation is being drafted for N₁vehicles of category Y (vehicles equipped with an automated driving system, not capable of manual driving exceeding 6 km/h, and not designed to carry occupants). The draft incorporates crash safety requirements from UN R94, UN R95, UN R137, and UN R153. Draft version 5 adds provisions for simplified approval procedures for previously approved vehicles, references UN R137 for vehicles between 2,500 and 3,500 kg, and clarifies B pillar references. Open issues include confirming non-applicability of lateral collision partial tests and clarifying which simplified procedures are permitted.

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.

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.

Proposal to amend para. 6.1.5. to state that sensors, cameras, radar devices, etc. being part of driver assist systems and automated driving systems may become damaged, disoriented or broken due to an impact as long as basic braking and steering performance remain intact. The amendment enables application of UN R42 to vehicles equipped with an Automated Driving System.

Agenda items include approval of the agenda and minutes of the previous meeting, feedback and status from GRSP-79, Joint closing meeting in Paris, and WP.29, Y-category Regulatory framework New for N₁, Y-category Pedestrian Protection UN Reg 127, UN Regulation No. 42, UN Regulation No. 134 Y-category exclusion, and any other business. Dates for next meetings are 4th September and 5th October with further meetings in November and December under consideration.

The 25th session of the GRSP Task Force on Automated Vehicles Regulatory Screening (AVRS) was held online on 28 April 2026. The Task Force discussed regulatory frameworks for Y-category vehicles, including mass compatibility and crash test exceptions, and reviewed UN Regulation 127 on pedestrian protection for Y-category vehicles. The Task Force also addressed UN Regulation 12 feedback and identified minor mistakes in three proposals: ECE/TRANS/WP.29/2026/63, ECE/TRANS/WP.29/2026/65, and ECE/TRANS/WP.29/2026/71, which require corrections before submission to WP.29.

TF-AVRS submitted a draft new Y-category Passive Safety Regulation to GRSP-79 in June 2026. The regulation addresses fuel system integrity, electrical shock protection, and crash compatibility for frontal, rear-end, and lateral collisions. The Task Force eliminated the R point problem, passenger compartment references, and A and B pillar designations, harmonised mass definitions, and consolidated numbering and cross-references. Open items include determining additional requirements, specific vehicle measurements, and finalising Annex elements. Subsequent informal documents are planned for GRSP-79, with working documents for GRSP-80.

UN R127 amendment proposals include defining pedestrian protection requirements for category Y vehicles. Scope exemptions for category Y vehicles shall use front structural geometry to determine exemptions, ensuring equivalence to R-point criteria. Definitions require adjustments including Bonnet Rear Reference Line for vehicles without windscreens, Front structure definition to include automated driving sensors, Windscreen test area redefined as Upper structure test area where windscreens are non-existent, and supporting definitions for Side reference line and Cowl monitoring area. Testing shall occur at Unladen Vehicle Mass.

Proposal to establish uniform provisions concerning approval of vehicles of category N₁ with regard to protection of fuel system integrity, protection against electrical shock, and vehicle crash compatibility in frontal, rear-end, and lateral collisions. The Regulation applies to vehicles of category N₁. Frontal impact provisions are based on UN R94 and UN R137 depending on vehicle mass. Lateral impact provisions are based on UN R95 without the side pole impact test. Rear-end impact provisions are based on UN R153. Vehicles must comply with fuel leakage limits, hydrogen storage system integrity requirements, and electrical safety standards for rechargeable energy storage systems. Post-crash hydrogen leakage shall not exceed 118 NL per minute, gas concentration shall not exceed 4.0 per cent for hydrogen, and containers shall remain attached at minimum one point. Electric power trains must meet protection against electrical shock, isolation resistance, and fire hazard requirements within 60 minutes post-impact. Conformity of production shall be verified on a statistically controlled random basis.

A new general safety regulation for vehicles of category Y is being drafted to collect relevant safety requirements. Vehicles of category Y with a maximum design speed not exceeding the impact speed specified in applicable frontal impact tests shall be exempted from frontal, lateral, and rear-end impact test procedures but must comply with applicable post-impact requirements concerning fuel leakage, hydrogen leakage, electrical safety, REESS electrolyte leakage, REESS retention, and fire or explosion hazards. The draft incorporates requirements from UN R94, UN R95, UN R137, and UN R153. Open issues include crash compatibility requirements for low-speed vehicles, applicability of partial tests, and defining front and rear structures for Y-category vehicles without occupants.

Proposal to insert a new para. 0 introducing amendments for vehicles equipped with an Automated Driving System, amend para. 1 to apply the Regulation to vehicles of categories M₁ and N₁ with specified exemptions and provisions for categories X and Y, amend the footnote to para. 1, amend para. 2.8 defining bonnet rear reference line with extended procedures for vehicles of category Y, amend para. 2.22 to include automated driving sensors in front structure for categories X and Y, amend para. 2.27 regarding mass in running order, amend para. 2.29 on normal ride attitude for categories X and Y, amend para. 2.32 on side reference line for category Y, amend para. 2.44 on windscreen test area for category Y without windscreen, amend para. 2.45 on cowl monitoring area, and amend para. 5.3.1.2 on Adaptive Ride Height Suspension engagement at low speeds.
