Proposal to amend rolling resistance provisions with regard to heavy-duty-use light trucks.

24. The expert from AAPC recalled GRBP-77-23 from the previous GRBP session and presented GRBP-78-33 with modifications to the rolling resistance values for LT-marked tyres. According to him, for reasons of safety and durability, some heavy-duty pickup trucks in a specific geographical region require LT-marked C3 tyres with performance characteristics suited to their use in rough terrains and for industrial/agricultural purposes which result in rolling resistance values higher than specified for C3 tyres in general. Therefore, he proposed to make an exception for such LT-marked C3 tyres in the rolling resistance tables.

25. The experts from France, ETRTO and OICA pointed out the need to study the proposal in more detail. Some experts feared that the requested exception for one region may have global implications. GRBP invited AAPC to liaise with the interested experts with a view to bringing more elements into consideration at the next session.

94. The representative of AAPC introduced GRPE-89-21. He requested guidance from GRPE on the best way to proceed to ensure full harmonization for OBD communication protocols in all regulatory tools under GRPE’s purview.

95. The representative of OICA confirmed that for light-duty vehicles, UN Regulations Nos. 83 and 154 were up to date, with a proposal to update UN GTR No. 15 expected for the next session of GRPE. He acknowledged SAE was the leading body on harmonized OBD communication protocols and highlighted the importance to be able to read Data Trouble Codes (DTCs) during periodic technical inspections.

96. The Vice-Chair mentioned OBD were used more widely than for emission related purposes, and that the newly created Vehicular Communication Task Force might be a good place to consider this topic if need be. The representative of OICA invited to reach out to SAE to know more about other OBD applications.

Request to allocate time on the agenda of the 78th session for consideration of performance requirements for tyres used on heavy-duty pickup trucks designed for professional tasks on rough terrains.

25. The expert from the American Automotive Policy Council (AAPC) briefly introduced GRBP-77-23 and requested that time be allocated for discussion at the next session. He pointed out that several Middle Eastern countries outside the 1958 Agreement implement national and regional requirements based on UN Regulation No. 117. In the region, specialized pickup trucks are used in oil fields, mining, agriculture, forestry and other rough terrains for heavy tasks. According to the expert, for safety and durability reasons, these vehicles require suitable tyres where the vehicle mass and tyre combinations do not permit compliance with the rolling resistance limits of UN Regulation No. 117. GRBP invited GRBP experts to provide feedback and agreed to address this issue in detail at the next session.

5. GRSG reviewed the proposals by IWG on EDR/DSSAD for Guidance on Event Data Recorder (EDR) Performance Elements Appropriate for Adoption in 1958 and 1998 Agreements (ECE/TRANS/WP.29/2020/100, as amended by GRSG-120-01 and GRSG-120-05), for a new UN Regulation on Event Data Recorder (ECE/TRANS/WP.29/2020/123, as amended by GRSG-120-02 and GRSG-120-05), and for a new 01 series of amendments to the new UN Regulation on Event Data Recorder (GRSG-120-03 and GRSG-120-05).

6. The expert from AAPC introduced document GRSG-120-06, on data elements for EDR. GRSG took note of the matters raised by the expert.

7. Following detailed technical discussions, including comments from experts from, Belgium, Germany, Italy, Japan, Netherlands, United Kingdom of Great Britain and Northern Ireland, United States of America, the European Commission, the AAPC and OICA, GRSG requested the secretariat to issue a consolidated version of amendments to document ECE/TRANS/WP.29/2020/100, proposal for Guidance on Event Data Recorder (EDR) Performance Elements Appropriate for Adoption in 1958 and 1998 Agreements Resolutions or Regulations, based on informal documents GRSG-120-01 and GRSG-120-05, as an official document with the unsolved elements between square brackets for consideration at the March 2021 WP.29 session.

8. GRSG adopted amendments to document ECE/TRANS/WP.29/2020/123, proposal for a new UN Regulation on Event Data Recorder, based on informal documents GRSG-120-02 and GRSG-120-05 and requested the secretariat to submit it as official document to WP.29 and AC.1 for consideration and vote at their March 2021 sessions.

9. Following detailed technical discussions, including comments from experts from, Belgium, Germany, Italy, Japan, Netherlands, United Kingdom of Great Britain and Northern Ireland, the European Commission and OICA, GRSG adopted a proposal for 01 series of amendments to the new UN Regulation on Event Data Recorder, based on informal documents GRSG-120-03 and GRSG-120-05 with square brackets removed related to the additional data elements (pages 22 and 23 of document GRSG-120-03) and requested the secretariat to submit it as official document to WP.29 and AC.1 for consideration and vote at their March 2021 sessions.

10. As the European Commission request to align transitional provisions with the dates provided by the EU General Safety Regulation did not find support by the other intervening contracting parties during the session, their representative envisaged that a related informal document would be provided by the European Commission to WP.29 for consideration at its March 2021 sessions, subject to the outcome of European Union internal process.
