Proposal to add provisions to the original OICA proposal concerning paragraph 7.5.2.2. to ensure that the vehicle approved for an industrial environment cannot be converted to adapt to residential environments without respecting the limits.

The presentation by the experts from UTAC/CERAM on the introduction of comprehensive, simple rating information to consumers, fleet operators and other stakeholders

72. The representative from UTAC/CERAM introduced GRPE-82-31-Rev-1 on the European Green NCAP and associated Green Vehicle Index (GVI) programs. The Chair requested the consortium to come back to GRPE when more results would be available. The representative from UTAC/CERAM confirmed more results would available in the coming months and another update could be envisaged when GRPE wishes to do so.

12. GRVA agreed to postpone the review of GRVA-07-38, a presentation on virtual testing prepared by the expert from France, at its next session.

7. The expert from France, Chair of the Informal Working Group (IWG) on Behaviour of M2 and M3 vehicles’ general construction in case of Fire Event (BMFE) introduced document GRSG-118-16, containing an overview of proceedings of the 8th and 9th sessions of the IWG on BMFE, the group’s activities and progress in the development of amendments to UN Regulations Nos. 107 and 118, and the schedule for upcoming sessions of the IWG. He invited GRSG experts to provide feedback on questions highlighted in the informal document. The expert also introduced document GRSG-118-02, containing a proposed amendment to UN Regulation No. 107.

8. GRSG considered GRSG-118-02 and requested its submission as an official document for consideration at the October 2020 session of GRSG. The Chair of GRSG invited delegates to submit further comments to be considered for addition to the proposal, if any.

Presentation on the use of simulation tools under type approval and in discussions on the validation of automated driving systems.

5. The expert from France introduced GRVA-04-07 informing on activities in his country concerning the development of a test centre for active safety, New Cars Assessment Programmes (NCAPs) activities, vehicle connectivity and automation.

28. The expert of OICA reported on a study with the aim to determine the inter-dependency between the rolling sound, rolling resistance and the main safety performances by carrying out tests according to regulatory or standard procedures (GRBP-70-25). The expert from OICA pointed out, that given the budget constraints, the study had focused on C1 tyres. The study results indicated a conflict between the rolling sound and safety performances, like wet grip, dry grip and lateral aquaplaning. According to the expert, a low level of rolling sound could not be proven as feasible without compromising other parameters essential for vehicle safety and CO2 emission reduction. He added that a full study report would soon be available. Various experts thanked OICA for the study and indicated they would further consider its results. The Chair invited experts to transmit their comments to OICA, if any.
