Input from the GRVA task force on the screening of WP.29 regulations for their fitness in application to Automated Driving Systems and ADS vehicles (FADS).

Guidance from GRVA regarding the review of WP.29 regulations for applicability to vehicles equipped with driving automation systems.

Report on the background and development of the text for a new UN GTR on laboratory measurement procedures for brake particulate emissions.

Proposal based on the 07 series of amendments to remove elements which covered by UN R154 (WLTP), to include references to the draft UN Regulation on Real Driving Emissions (RDE), and to update In-Service Conformity (ISC) requirements for the purposes of establishing regional type approval equivalence. The proposal is incomplete. The EC expects to provide missing elements before the 87th GRPE session in January 2023. This document is available with mark-ups in pdf version and in docx format.

Proposal to permit the use of hydrogen (H2) as fuel for emissions type approval of heavy-duty vehicles.

Proposal to postpone the work on a GTR until after pending national/regional legislation has been enacted (e.g., Euro 7 and US proposal on light vehicle emissions).

Proposal to harmonize the requirements of the 06 and 07 series of amendments, align with UN R48 wording to ensure consistent type-approval test conditions with the introduction of the 08 series of amendments (to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption). The aim of the document is to reach consensus to enable adoption of a proposal during the next GRPE session (88th session in June 2023).

Proposal for changes to the draft amendments to the 05, 06, and 07 series per the following justifications:

1. In GRPE-86-12, the introduction of SAE J 1979-2 was proposed for Series 05, 06 and 07 of Regulation No. 83. Due to the different structure of Series 05 and 06 compared to 07, this proposal was not adopted. This proposal introduces the new standard to Series 05 and 06 and aligns the standards with Series 07.
2. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). These standardisation body have to be informed.
3. Alignment of wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence, where “or engine” was missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.
4. Align Paragraph 6.5.1.3. with GTR No. 15 to avoid ambiguity.

Proposal to ensure consistency in the vehicle categories within scope across emissions regulations and with regional requirements within Europe.

1. The current scope of the proposed UN Regulation on RDE (GRPE/2023/3) does not cover all vehicle categories within scope of other UN emissions regulations relevant for light duty vehicles and is inconsistent with regional legislation within the UK and Europe.
2. The proposed amendment seeks to allow Contracting Parties to optionally apply this regulation for vehicle category N2 and for M2 vehicles above 3,500 kg technical permissible maximum laden mass when the reference mass is below 2,610 kg. This would enable equivalent coverage of the scope to regional requirements in Europe and the acceptance of a full UNECE emissions regulation package for those vehicle categories in that region.
3. Provisions relating to the extension of type approvals to vehicles with a reference mass not exceeding 2,840 kg have also been applied to categories M2 and N2 where Contracting Parties are applying the broader scope of vehicle categories.
