He proposed to introduce in a new 02 series of amendments provisions regarding the performance of AEBS for vehicles of category M1 and N1 and to introduce in a new 03 series of amendments provisions addressing the performance of such systems for those vehicle categories and the detection of pedestrians. He introduced GRRF-83-18 proposing terms of reference for the Informal Working Group (IWG) on AEBS. The expert from OICA noted the challenging timeline proposed.

7. GRRF supported the proposal made by the expert from Japan and endorsed the draft Terms of Reference proposed for the IWG on AEBS as reproduced in Annex II of the session report.

8. The expert from OICA introduced GRRF-83-22, proposing clarifications to the provisions related to the stability control optical warning in Regulations No. 13, 13-H and 140. He explained that, to date, braking regulations explicitly permitted the use of the Electronic Stability Control (ESC) flashing symbol for the purpose of showing interventions of systems related to the vehicle stability function (e.g. traction control etc.). He added that with the proposed clarification, it would be clarified that the use of the ESC flashing symbol would be permitted for indicating the intervention of individual steering control for vehicle stability such as Corrective Steering Functions, if related to the vehicle stability function.

9. GRRF agreed to resume consideration of this document while reviewing the proposal on Automatically Commanded Steering Function (ACSF) under agenda item 9.

10. GRRF did not receive any new document to be discussed under this agenda item.

11. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/GRRF/2013/13, adopted during the seventy-fifth GRRF session. The document remained on the agenda of GRRF, pending submission to the World Forum for Harmonization of Vehicle Regulations (WP.29) and the Administrative Committee of the 1958 Agreement (AC.1) of the adopted text for Regulation No. 89 (Speed limitation devices).

12. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRRF/2017/2 proposing to delete an obsolete provision in Annex 5 to Regulation No. 13.

25. The expert from Spain reported on behalf of the Special Interest Group (SIG) on Regulation No. 90 on the outcome of the group following two meetings (GRRF-83-26). He mentioned that the group of experts considered a list of issues for future consideration. He added that the group already reached a common understanding about the type definition interpretation of replacement parts. He concluded that a final report would be delivered at the September 2017 session of GRRF, with a potential recommendation for the establishment of an informal working group on Regulation No. 90 (and corresponding draft terms of reference), if the experts would conclude that it is necessary. He announced that the next meeting of the SIG would be organized in April 2017 and requested that the secretariat circulate an invitation by email.

26. The experts from OICA and CLEPA expressed concerns with elements of the presentation of the expert from Spain. The Chair of GRRF noted the number of items for consideration and advised the group of experts to define priorities and to separate the work that would cause an extension of scope of the Regulation e.g. replacement calipers.

27. The expert from Spain recalled the discussion that took place at the seventy-fifth session of GRRF (ECE/TRANS/WP.29/GRRF/75, para. 49) and that was related to safety issues on proving grounds or on public roads linked to braking tests.

GRRF noted that Annex 5 was containing non-metric tyre sizes not in line with the general formulae contained in the Regulation; therefore, GRRF wondered whether the right approach would be to introduce the appropriate formulae in the Regulation instead of continuously updating Annex 5. The expert from ETRTO agreed to address this proposal and to submit, if suitable, revised proposals for consideration at the next session.

37. The expert from ETRTO presented GRRF-83-15 with new tyres sizes to be included in Annex 5. GRRF adopted the proposal.

38. The expert from ETRTO presented a revised proposal ECE/TRANS/WP.29/GRRF/2017/9 with provisions which were already supported at the last session. He introduced the revised transitional provisions related to new marking requirements. The experts from EC and UK proposed an alternative wording (GRRF-83-14). Both proposals received several comments. Therefore GRRF agreed to adopt the agreed provisions that would not be subject to transitional provisions and to remove the others, as reproduced in GRRF-83-23.

39. GRRF requested the secretariat to submit the adopted proposals ECE/TRANS/WP.29/GRRF/2017/9 amended by Annex VI (based on GRRF-83-23 and GRRF-83-15) as well as ECE/TRANS/WP.29/GRRF/2016/39 as draft Supplement 15 to Regulation No. 106 (Agricultural tyres) to WP.29 and AC.1 for consideration and vote at their June 2017 sessions.
