48. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2017/23 as amended by GRRF-84-22 with provisions to be included in UN Regulations Nos. 13, 13-H, 79 and 140 related to the stability control warning activation by Corrective Steering Functions and Automatically Commanded Steering Functions. The proposal received some comments. GRRF amended the proposal as reflected in GRRF-84-39.

49. GRRF agreed with the proposal as amended by Annex V of the GRRF session report and requested the secretariat to submit it [together with GRRF-84-22] as draft supplements to Regulations Nos. 13, 13-H, 79 and 140 to WP.29 and AC.1 for consideration and vote at their March 2018 sessions.

50. The expert from Germany on behalf of the Co-Chair of the IWG on Automatically Commanded Steering Function (ACSF) presented GRRF-84-02 with draft provisions for ACSF of Category [C1]. GRRF discussed values in square brackets in the document related to the scenario considered for the purpose of testing the performance of ACSF of C1 category. In particular, the definition of the point at which, following the beginning of the Lane Change Procedure, the driver’s reaction should be understood did not achieve consensus and created difficulties to agree on what is referred to as reaction time in draft para. 5.6.4.8.1. The expert from Japan presented GRRF-84-28 proposing derogations in case the maximum speed allowed in the territory of a Contracting Party would be lower than 130 km/h. GRRF agreed to defer GRRF-84-28 to the IWG on ACSF. GRRF considered the note from the secretariat (GRRF-84-24) reproducing comments received from Tesla Inc. GRRF also discussed GRRF-84-23 tabled by the experts from OICA and CLEPA on Emergency Steering Functions. GRRF requested the secretariat to consolidate the proposals as reflecting the current position and guidance of GRRF (GRRF-84-36) and to add this consolidation to the provisional agenda of the next session of GRRF (ECE/TRANS/WP.29/GRRF/2017/26). GRRF also requested the IWG on ACSF to review this document until the next GRRF session.

54. The expert from UK introduced GRRF-84-14 proposing amendments to the requirements in Annex 6 (Complex Electric control systems). GRRF reviewed in detail the proposal and requested the secretariat to include the amended proposal in the consolidated document GRRF-84-36 and ECE/TRANS/WP.19/GRRF/2017/27.

5. The Chair of GRRF recalled the purpose of ECE/TRANS/WP.29/GRRF/2017/27 proposing amendments to UN Regulation No. 79 with provisions for Automatically Commanded Steering Function (ACSF) of Category C, Emergency Steering Function (ESF) and clarifications to Annex 6. He mentioned that the Informal Working Group (IWG) on ACSF held two meetings and a webex conference since the September 2017 session of GRRF to review this document.

12. GRRF adopted ECE/TRANS/WP.29/GRRF/2017/27 with the amendments endorsed during this session concerning ACSF of Category C, ESF and Annex 6, as reproduced in Annex II to the session report and requested the secretariat to submit it as draft 03 series of amendments to UN Regulation No. 79 to World Forum for the Harmonization of Vehicle Regulations (WP.29) and Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their March 2018 sessions.

48. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2017/23 as amended by GRRF-84-22 with provisions to be included in UN Regulations Nos. 13, 13-H, 79 and 140 related to the stability control warning activation by Corrective Steering Functions and Automatically Commanded Steering Functions. The proposal received some comments. GRRF amended the proposal as reflected in GRRF-84-39.

49. GRRF agreed with the proposal as amended by Annex V of the GRRF session report and requested the secretariat to submit it [together with GRRF-84-22] as draft supplements to Regulations Nos. 13, 13-H, 79 and 140 to WP.29 and AC.1 for consideration and vote at their March 2018 sessions.

89. In ECE/TRANS/WP.29/2018/8, the title, for “Supplement 1 to the 01 series”, read “Supplement 17 to the 00 series”.

48. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2017/23 as amended by GRRF-84-22 with provisions to be included in UN Regulations Nos. 13, 13-H, 79 and 140 related to the stability control warning activation by Corrective Steering Functions and Automatically Commanded Steering Functions. The proposal received some comments. GRRF amended the proposal as reflected in GRRF-84-39.

49. GRRF agreed with the proposal as amended by Annex V of the GRRF session report and requested the secretariat to submit it [together with GRRF-84-22] as draft supplements to Regulations Nos. 13, 13-H, 79 and 140 to WP.29 and AC.1 for consideration and vote at their March 2018 sessions.

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.
