33. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/19 proposing amendments to UN Regulation No.79 based on experience gathered by France, Germany and the Republic of Korea since the entry into force of the 03 series. The proposal received comments (see GRVA-04-09, GRVA-04-46). GRVA adopted the proposal as amended (GRVA-04-47) as reproduced in Annex III, as supplement to the 03 series of amendments to UN Regulation No.79 and requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their March 2020 sessions.

34. The expert from AVERA presented GRVA-04-53, introducing ECE/TRANS/WP.29/GRVA/2019/26, ECE/TRANS/WP.29/GRVA/2019/27 and ECE/TRANS/WP.29/GRVA/2019/28. The presentation contained videos, simulations and fleet data supporting the proposals for amendments to UN Regulation No. 79. The presenters referred to a driving demonstration organized by Tesla in conjunction with GRVA to justify their statements. The proposal received some comments. The contracting parties were not opposed to an evolution of the regulatory provisions based on experience, if the assurance of safety is provided. The expert from AVERE presented revised proposals GRVA-04-41 and GRVA-04-42 aimed at addressing comments received. GRVA noted that some parts of the proposals were also addressed by the proposal submitted by the expert from OICA and agreed to review it.

35. GRVA welcomed the proposal from the expert from the United Kingdom, who volunteered to lead activities on the review of the three AVERE proposals as well as the amendment proposal tabled by OICA in GRVA-04-08 with the aim to prepare a formal proposal until November 2019 in order to meet the deadline for submission of documents for the February 2020 session of GRVA.

35. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/9 based on GRRF-86-13 proposing clarifications of the Annex 8 testing provisions. The proposal received some comments from Japan, France, Germany and OICA. The expert from France agreed with the suggestion of GRVA to submit a revised proposal with more data for consideration at the September 2019 session. The experts from Japan, Germany and OICA were invited to share with GRVA their test data, supporting their positions.

48. The expert from Germany presented GRRF-86-13 tabled by the experts from Germany and from the Republic of Korea with a proposal for amendments to the ACSF testing provisions in Annex 8 of UN Regulation No. 79, based on the first experience gathered since the 02 series of amendments of UN Regulation No. 79 entered into force. GRRF welcomed the proposal and provided comments. The experts from Germany and the Republic of Korea volunteered to prepare a revised proposal aimed to avoid prescriptive requirements on the measurement instruments and providing more detailed justification e.g. on the sample rate and the filtering of the lateral acceleration data.

53. The expert from France introduced GRVA-01-38 (based on GRRF-86-13) addressing the accuracy of interpretation of data produced during system assessment. The expert from Germany welcomed the document and proposed to consider the filtering provisions together with the tolerances. Other experts welcomed the document and agreed to study it until the next session. GRVA agreed to resume consideration of this item at its January 2019 session.
