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 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.

Proposal to insert a new para. 5.1. requiring that features for design or aerodynamics in the head impact zone shall not impose an additional cause of danger to pedestrians and other vulnerable road users and shall not exhibit openings or contain materials that may increase the risk or seriousness of injury, and renumber paragraphs 5.1. to 5.2. as paragraphs 5.2. to 5.3. This aims to maintain pedestrian safety as requirements become mandatory for small-series vehicles according to Commission Delegated Regulation (EU) 2022/2236 from 7 January 2026, addressing hazards from openings in the head impact zone that may trap impacted heads or permit head intrusion and from bonnet materials like plastics that may deform or fracture, creating injury risks not currently addressed by UN R127’s component tests.

Proposal to insert a new para. 0 introducing supplements 4 and 5 to the 04 series of amendments extending the Regulation to vehicles of categories X and Y, amend para. 1 to modify scope provisions and add R-point clarifications for category X vehicles, amend para. 2.8 to revise the bonnet rear reference line definition including provisions for category Y vehicles without windscreens, amend para. 2.22 to clarify front structure definition for categories X and Y, amend para. 2.29 to specify occupant mass placement for categories X and Y, amend para. 2.32 to define side reference line for category Y vehicles, amend para. 2.44 to redefine windscreen test area for category Y vehicles, and amend para. 2.45 to adjust cowl monitoring area for category Y vehicles.

Proposal to transpose GTR-9 Amendment 3 (ECE/TRANS/WP.29/2024/77) on technical requirements for Deployable Pedestrian Protection Systems, amend Chapter 0 Introduction, amend para. 2. to add provisions for vehicles equipped with DPPS and measurements taken with system undeployed, delete footnotes 2 and 3 from para. 2.1., replace reference to 2.27. by 2.29. in para. 2.31., delete footnotes 5 and 6 from paras. 2.43. and 2.45., insert new paras. 2.50. to 2.61. defining DPPS-related terms including Deployment Time, Detection test area, Head Impact Time, Sensors and Testing of DPPS, amend para. 4.2. to delete approval number supplementation provisions, delete para. 4.4.3., amend paras. 5.2. to 5.2.2. to reference Annex 7 requirements when tested with DPPS activated, replace paras. 11.1. to 11.25. with transitional provisions and insert paras. 11.26. to 11.29. establishing that as from entry into force Contracting Parties shall not refuse type-approvals under 05 series amendments, as from 1 September 2031 shall not accept prior series approvals first issued after that date, shall continue accepting prior approvals first issued before 1 September 2031, and shall continue granting approvals using atypical windscreen fracture procedures until 1 September 2033, amend Annex 1 para. 9.23.1., amend text under Annex 2 heading, amend Annex 3 para. 3.2., and insert new Annexes 7 and 8 establishing test procedures for DPPS including prerequisites, HIT verification methods, headform test procedures, HBM qualification, and documentation requirements.

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.

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.

The 26th meeting of GRSP TF on AVRS is scheduled for Tuesday 22nd of May 2026 as an online meeting from 09:00 to 11:00 CEST. The agenda includes approval of the agenda and minutes, feedback from other meetings, consistency check of GRSP ADS fitness work, Y-category regulatory framework for N₁, Y-category pedestrian protection under UN R127, feedback on passive safety requirements for new steering equipment types, any other business, and dates for next meetings.

A decision was taken in mid-2025 to start drafting a new regulation for category Y vehicles. TF AVRS agreed to amend UN R127 to include Y-category vehicles. Supplement 5 to the 04 series of amendments proposes: for vehicles of category Y, dimensions based on front structural geometry shall determine exemptions ensuring equivalence to R-point criteria; Bonnet Rear Reference Line is defined for category Y vehicles without a windscreen; Front structure definition includes outer structures and, for category X and Y, automated driving sensors essential for vehicle operation; Normal ride altitude testing shall be at Unladen Vehicle Mass.
