The Task Force reviewed and approved regulatory amendments for ADS-equipped vehicles across multiple UN Regulations. Key decisions included adopting a simplified and consistent definition of ‘vehicle user’ for light-duty and heavy-duty vehicles, retaining original wording for warning signal transmission to ADS systems, and amending engine torque terminology under UN R49. Amendments were reviewed for UN R49, UN R83, UN R115, UN R154, UN R177, UN R179, and UN R180, with focus on consistency regarding ADS testing modes and an additional 25 kg mass allowance for vehicles of categories X and Y. The Task Force acknowledged that ADS operation may result in additional energy consumption not fully reflected in current testing procedures and agreed to seek GRPE guidance on possible future work.

Provisional agenda for the 35th meeting of the AVRS Task Force scheduled for 12 October 2026, including adoption of agenda, review of minutes from the previous meeting, discussion of a proposal for a Supplement to the 02 and 03 series of amendments to UN R154, discussion on ADS vehicles and their energy consumption and continuation of the Task Force mandate, a status report on GRPE-95, and any other business.

Task force in-session amendments to the proposal to amend para. 0. to introduce provisions for vehicles of category Y and Automated Driving Systems, amend para. 1.4. to exclude category Y vehicles and exempt certain category N₁ vehicles, add sentences to paras. 2.8., 2.22., 2.29., 2.32., 2.45. defining or clarifying applicability for category Y vehicles, amend para. 2.44. to define windscreen test area for category Y vehicles without windscreens, and replace language in para. 5.3.1.2. to refer to active ADS rather than ADS performing the Dynamic Driving Task.

Task force in-session amendments to the proposal to insert a new introduction paragraph accounting for vehicles of category X and Y, amend para. 6.1.5. to clarify that the exemption for driver assistance systems does not fully apply to automated driving systems where the perception system forms part of the driving function, and make editorial improvements replacing ‘disoriented’ with ‘misaligned’ and ‘driver assist systems’ with ‘driver assistance systems’.

Proposal to:

• insert a new paragraph 0 introducing the amendment to account for vehicles of categories X and Y, stating that the Regulation was originally drafted for vehicles with a driver and manual driving controls and is being extended to vehicles without a driver and without manual driving controls, that in manual driving mode no special provisions apply to vehicles equipped with an Automated Driving System other than vehicles of categories X and Y, and that vehicles of category Y are exempted based on front structure geometry rather than driver “R” point position
• amend paragraph 1.2 to provide that for vehicles of category X, the “R” point of the most forward passenger seat shall be taken instead of the R-point of the driver’s seat
• amend paragraph 1.3 to provide that for vehicles of category X, the “R” point of the most forward passenger seat shall be taken instead of the R-point of the driver’s seat
• amend paragraph 1.4 to delete the statement that this Regulation does not apply to vehicles of category Y and instead provide that vehicles of category N1Y where a specified equation is fulfilled are exempted
• amend paragraph 2.8 to revise the definition of “Bonnet rear reference line” and provide that for vehicles of category Y without a windscreen, the BRRL is defined as the geometric trace of the most rearward points of contact between the sphere and the front structure as it is traversed across the vehicle’s rearward edge
• amend paragraph 2.22 to provide that for vehicles of categories X and Y, automated driving sensors that are essential for the vehicle’s operation and cannot be stowed during driving should be considered part of the “Front structure”
• amend paragraph 2.29 to provide that for vehicles of category X, two passenger masses are placed on the front seats instead of driver and one passenger masses, and for vehicles of category Y, no occupant mass is added
• amend paragraph 2.32 to provide that for vehicles of category Y where A-pillars are non-existent, side reference lines also define the lateral limits for the total test area
• amend paragraph 2.44 to provide that for vehicles of category Y where a windscreen is non-existent, the windscreen test area is defined as the “Upper structure test area” with specified front, rear, and side boundaries
• amend paragraph 2.45 to provide that for vehicles of category Y where a windscreen is non-existent, the cowl monitoring area is bound in the rear by the front of the “Upper structure test area”
• amend paragraph 5.3.1.2 to provide that ARHSS shall automatically return to normal ride height while an ADS feature is active

This Regulation establishes uniform provisions for crashworthiness approval of N₁Y vehicles regarding fuel system integrity, electrical shock protection, and crash compatibility during frontal, rear, and lateral collisions. The provisions for frontal impact are based on UN R94 or UN R137 per manufacturer choice with Technical Service agreement; lateral impact provisions are based on UN R95; rear impact provisions are based on UN R153. Vehicles with maximum design speeds not exceeding applicable impact speeds shall be tested at their maximum design speed and comply with post-impact requirements. Crash Compatibility Criterion shall not exceed 40–45 g and Crash Compatibility Value shall not exceed 100–120 g×tonne. For vehicles derived from types already approved under UN R94, UN R137, UN R95, or UN R153, previous test results may be used if mass increases do not exceed 8 per cent.

Minutes from the 27th meeting of GRSP TF on AVRS held Wednesday 1st July 2026 online. The agenda and previous minutes were approved. EC reported from June WP.29-199 TF Expert FADS and presented WP.29-199-19. GRSP TF AVRS must complete crashworthiness regulation for Category Y and Pedestrian Protection R127, GRE TF AVSR ADS marker lamps, GRE IWG EMC refinements for ADS in 10R08, and GRPE TF AVRS amendments to UN Regulation No. 154. Regarding amendment proposals to UN Regulations Nos. 35 (ECE/TRANS/WP.29/2026/104) and 68 (ECE/TRANS/WP.29/2026/146), AC.1 postponed voting to the next session due to required quorum not being attained. EC presented updates on Y-category regulatory framework for N₁, Y-category Pedestrian Protection UN Reg 127, and UN Regulation No. 42 and 134. Next meetings scheduled 4th September, 5th October, week 4, 24th November or 1st December, and 7–11 December.

Proposal to insert a new Introduction section containing provisions for vehicles of categories X and Y, amend the Scope to include vehicles of categories X and Y with specific exemptions based on the “R” point or front structural geometry, amend definitions of “Bonnet rear reference line,” “Front structure,” “Normal ride attitude,” “Side reference line,” “Windscreen test area,” and “Cowl monitoring area” to address vehicles of categories X and Y, and amend paragraph 5.3.1.2. regarding Automated Riding Height Suspension System engagement conditions. Changes compared to document ECE/TRANS/WP.29/2026/53 are indicated by red markup.

Proposal to simplify text on AV screening in the GID Introduction section. The revised text condenses the explanation that AV screening amendments to WP.29 Regulations are outside the scope of the GID. The original lengthy paragraph explained WP.29’s screening process, task forces, and technical requirements for systems such as braking, steering, and lighting. The revised text concisely states that WP.29 has updated its regulations concerning aspects of the DDT to enable their application to ADS vehicles, and these AV-related amendments are outside the scope of this document.

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.
