Session 2 | Geneva | 28 Jan-1 Feb 2019
Agenda Item 5. (d) Automatically Commanded Steering Function
Working Party on Brakes and Running Gear | Session 86 | 12-16 Feb 2018

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.

57. The GRRF chair mentioned that document ECE/TRANS/WP29/2018/35 would still contain square brackets. WP.29 agreed to remove the square brackets and to agree on transitional provision dates (as reflected in para. 92).

92. In ECE/TRANS/WP.29/2018/35, paragraphs 2.1.4., amend to read:

12.2.2.As from 1 September 2019, Contracting Parties applying this UN Regulation shall not be obliged to accept UN type approvals to the preceding series (02) of amendments, first issued after 1 September 2019.
12.2.3.Until 1 September 2021, Contracting Parties applying this UN Regulation shall continue to accept UN type approvals to the preceding series (02) of amendments to the UN Regulation, first issued before 1 September 2019.
12.2.4.As from 1 September 2021, Contracting Parties applying this UN Regulation shall not be obliged to accept type approval issued to the preceding series of amendments to this UN Regulation.

93. WP.29 noted the concern raised by the representative of OICA on the selection of an early date of application for the transitional provisions in paragraphs 12.2.3. and 12.2.4., which could create serious development difficulties, due to the introduction of new requirements compared to the very recently adopted 02 series of amendments, while vehicles are currently under development for the latter.

Working Party on Automated and Connected Vehicles | Session 1 | 25-28 Sep 2018

29. The expert from OICA presented ECE/TRANS/WP.29/GRVA/2018/2, as amended by GRVA-01-22 introducing provisions for ACSF systems of Category C with a so called 2-steps human machine interface for the lane change activation. The expert from France supported the proposal. The expert from the European Commission welcomed this proposal. The proposal received some comments from the experts from Germany, Korea, Netherlands, and Sweden namely on the deletion of some provisions, the proposed amendment to extend the time by which a lane change manoeuvre shall begin and the proposed Annex 9. GRVA invited interested experts to prepare a revised proposal addressing the comments received.

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.

Working Party on Automated and Connected Vehicles | Session 2 | 28 Jan-1 Feb 2019

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.

36. The expert from France introduced ECE/TRANS/WP.29/GRVA/2019/10, proposing clarifications to the tall-tell requirements for Corrective Steering Function (CSF), Emergency steering Function (ESF) and ACSF. GRVA adopted the proposal as amended and reproduced in Annex III. GRVA requested the secretariat to submit Annex III to the report as draft Supplement 1 to the 03 series of amendments to UN Regulation No. 79 to WP.29 and the Administrative Committee of the 1958 Agreement (AC. 1) for consideration and vote at their June 2019 sessions.

37. The expert from OICA introduced GRVA-02-24 (based on ECE/TRANS/WP.29/GRVA/2018/2), proposing to insert in the Regulation some provisions for ACSF of Category C with a two-step Human Machine Interface (HMI) approach. The expert from the Netherlands disagreed with the proposed seven seconds as the time during which the second deliberate action by the driver should take place while this time for the one-step HMI approach (latest time by which an automatic initiation should occur), already in force, is limited to five seconds. The expert from France supported the proposal and showed flexibility on the seven seconds value to reach consensus among CPs. The expert from Germany asked whether this proposal would allow one single vehicle to be equipped with both a one-step HMI and a two-step HMI and how the combination of both would work. GRVA invited OICA to consider the issues raised by the experts and requested the secretariat to distribute the proposal with an official symbol for review at its September 2019 session.
