1. Update from RDE IWG GRPE January 2019 From the sponsors: European Union Japan Korea

2. Background
During last GRPE meeting, EU, Japan and Korea requested the creation of an RDE IWG
The GRPE accepted the proposal during its June 2018 meeting
Creation of RDE IWG accepted by AC.3 in its June 2018 meeting
The relevant portions from the minutes are reported in the following slides

3. 147.          The representative of the European Union … requests authorization to develop a new UN GTR on Global RDE. She highlighted the importance of this request, both technically and politically, with emissions control strategies now being globally developed by vehicle manufacturers.
148.          The timeline to develop the new UN GTR on Global RDE is ambitious due to the urgency to tackle the topic in a harmonized, coordinated approach. The process will be opened to all contracting parties interested in developing or improving their own national regulatory procedures.
149.          The representatives of Japan and the Republic of Korea supported the document and expressed the wish to participate in the IWG on Global RDE.
150.          The representative of the United States of America expressed his support for GRPE to begin exploring a harmonized test procedure on RDE, as soon as possible, through the work of an IWG on Global RDE.

4. 151.          He expressed his support of a data-driven approach that would be inclusive of input from all the contracting parties, and that it would not be pre-determined that the European RDE is the only approach which should be considered.
152.          The representative of the United States of America expressed his belief that more time will be needed to be able to consider all inputs from all contracting parties.
153.          The representative of the United States of America stated that this work could lead to a UN GTR, though he did not believe that it was necessary at this time to make this decision. He added that an IWG should be formed to explore the development of a harmonized RDE methodology and at a future meeting of WP.29/AC.3 it could be decided, based on a more inclusive input from the contracting parties, if a UN GTR under the 1998 Agreement  would be the appropriate approach.

5. 154. The representative of the United States of America stated that if AC.3 decides to move forward with the development of a UN GTR on Global RDE, the United States of America would participate in the early stages of the development. However, if the process was not data-driven nor inclusive of input from all contracting parties to the 1998 Agreement, the United States of America would consider exercising the right as a contracting party to make clear that it would not support the eventual adoption of a UN GTR for this new methodology AC.3 took into consideration the comments of the representative of the United States of America and granted authorization to develop a UN GTR on Global RDE. The request for authorization to develop a new UN GTR on Global RDE is reproduced in annex V of this report.

6. 156. The Chair of GRPE congratulated all the parties who showed interest in participating in the development strengthened so as to ensure the adequate operation of state-of-the-art emission control systems in normal conditions of use He emphasized that the development of a harmonized real driving emissions test procedure would centralize expertise and resources for improved emissions measurement. This would also support significant economies of scale across the automotive sector.

7. Meetings The group met already on: 11-12 September 2018 in Brussels
27-28 November 2018 in Brussels
9 January 2019 in Geneva
And planned next meeting for 1-2 April 2019 in Japan

8. Confirmed Roles: Chair: European Union (P. Dilara)
Vice-chairs: Japan (Y. Kono) and Korea (J. Park)
Secretaries: OICA (P. Mendoza-Villafuerte), JASIC (N. Ichikawa)

9. 1st Meeting
Presentation of development of the RDE methodology in Europe
Presentation of Japanese methodology
Presentation and discussion of the joined text of the two methodologies, based on the RDE4 version
Discussion on ToR
Work is needed in order to understand how other CPs driving and boundary conditions can be taken into account

10. 2nd Meeting Presentation of Indian RDE methodology
Presentation of the scope of the US work for RDE development
Continuation of the discussion on a consolidated text
Presentation by JRC of changes made in the RDE4 act
Presentation of the OICA position

11. 3rd Meeting Presentation of Korean RDE methodology
Presentation by JRC of testing guidelines and of RDE data and tool available by JRC
Discussion on creation of a common RDE database with data relevant for the further development of RDE GTR
Discussion on ToR, tasks and timeline

12. Work on the RDE GTR GTR should contain only technical procedures
The group is considering how to adapt the procedures in order for them to work in various regions
Extra testing may be required
The issue of how to deal with the uncertainty of measurements is still open
CEN is developing a standard on the performance of PEMS
In case this is not ready in time, we will need to take this up in the GTR

13. Detailed task list-1 Driving and emission data collection: 1 June 2019
Evaluation of Temperature and Altitude boundaries using regional needs: first delivery by 1 April 2019 meeting in Tokyo
Evaluation of cumulative altitude gain: 1 April 2019
Introduction of certification lab cycles other than WLTP (FTP, MIDC,…): first delivery on 1 October 2019, final delivery end 2019*
*in case the work cannot be performed in time for having a draft text by end of 2019, maybe to be postponed for second phase.

14. Detailed task list-2
Evaluation of trip composition: first delivery April meeting, final for June 2019
Annex on uncertainty of measurements: October 2019
Evaluation of trip severity/trip dynamics: First delivery for June 2019
