3. (c) Worldwide harmonized Real Driving Emissions (RDE) test procedure
|
39. The representative from the EC introduced ECE/TRANS/WP.29/GRPE/2023/3. This document is submitted by the experts of Japan and the European Commission. The text contains changes introduced into European legislation (Euro 6e) since the adoption of the previous version of the draft UN Regulation on RDE prepared by GRPE at its eighty-first session (ECE/TRANS/WP.29/GRPE/81/Add.2 and ECE/TRANS/WP.29/2020/120). The representative from OICA introduced GRPE-87-08 and GRPE-87-09. The representative from Japan supported ECE/TRANS/WP.29/GRPE/2023/3 and GRPE-87-08. The representative from the European Commission had some objections to some elements included in GRPE-87-08 and sought further clarification to make sure over-regulation is not included in the proposal, as might be the case where requiring not to perform RDE trips in reverse gear.
40. The representative from OICA highlighted absolute legal clarity was needed, as stakeholders in other fora had made statement about attempts to make vehicles fail RDE tests, legally compliant but driven in unrealistic conditions.
41. The representative from the European Commission did not support GRPE-87-09, requesting to try and avoid repeat the sub-optimal situation that led to last resort decision in other GRPE legislation and confirmed the European Commission had no mandate to agree on the inclusion of 2 levels in UN Regulation on Global RDE. The representative from Italy understood the intention of the OICA’s proposal, and was open to OICA’s proposal in the spirit of harmonization that is operational.

Proposal to clarify and improve the text of the new Real Driving Emissions type approval regulation per the following justifications:
- In paragraph 3.3.7. the text in brackets is a repeat of content in an Annex. It is good practice to keep definitions to one sentence where possible. Adding “of the tested vehicle” avoids any confusion with family test mass definitions.
- The syntax of the term “power-to-mass-ratio” (with hyphens between all words) should be consistent throughout the document.
- Where a requirement only applies to the approval authority which issued the approval this should be made clear in the text.
- Additional to the technical specifications listed in Annex 5, the Regulation assumes measurement accuracy of PEMS equipment. It therefore appears reasonable that the PEMS equipment is required to also deliver these measurement accuracy.
- As vehicles are designed to be driven predominantly forwards, and rearwards driving although normal practice is an exceptional situation, the possibility to drive rearwards for extended periods should be removed.
- “Velocity” as a physical term is a vector and has to be accompanied by a direction. For clarity this should be replaced with “speed”.
- A large (> 20 K) ambient temperature difference between one day and the next is not representative of real life and can result in unrepresentative catalyst performance. The possibility of a preconditioning at 23 °C followed by a test at below freezing should therefore be removed.

Proposal to introduce levels in the draft new UN Regulation on Real Driving Emissions type approvals based on the following: - Since RDE testing has been introduced in the European Union, there has been criticism of the difficulties encountered when planning a valid RDE test.
- This situation would be worsened by introducing the requirement for a test to be suitable for analysis according to both 3-phase and 4-phase concepts.
- As levels have already been introduced in Regulation No. 154 and these are becoming accepted and understood by technical services and approval authorities, the introduction of these levels in this Regulation would be a clear alignment.
- As the temperature boundary conditions from this draft Regulation are already being transposed into European legislation, OICA members see no need to differentiate between boundary conditions for the proposed levels.
- The inclusion of these few amendments would return the planning burden to that currently experienced in the EU, at least for markets which apply the 4-phase WLTP concept.

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

46. The representative from the European Commission, Co-chair of the IWG on RDE, introduced GRPE-87-51, requested a delay in the authorization to develop a new UN GTR on Global RDE. The representative from the US, Co-Chair of the IWG on RDE, supported the proposal and added that the activities would be paused and not ended, as the topic was important and should be tackled as soon as possible. As consequence, the Chair declared that the activities of the IWG on RDE are put on-hold until further notice.
47. GRPE adopted GRPE-87-51, as reflected in Annex IX to the session report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2023 sessions as revised authorization to develop a UN GTR on Global Real Driving Emissions (RDE).
