Proposal for amendments to the requirements for Automatically Commanded Steering Functions (ACSF) of Category C, introducing specific provisions for the use of a lane change function with a two-step Human Machine Interface (HMI).

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.

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.

Proposal to introduce provisions for a “two-step Human Machine Interface” in the requirements for Automatically Commanded Steering Functions (ACSF) of Category C lane-change functions.

36. The expert from OICA presented GRVA-04-03, introducing ECE/TRANS/WP.29/GRVA/2019/24 proposing an alternative Human Machine Interface (HMI) for ACSF of Category C. The proposal received comments (and GRVA extended the discussion after the end of the official meeting time, without interpretation and without decisions or conclusions).

37. Following further discussion, GRVA adopted the proposal as amended (GRVA-04-43) and reproduced in Annex IV. GRVA requested the secretariat to submit it to WP.29 and AC.1, for consideration and vote at their March 2020 sessions.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF). This proposal includes amendments the annex on complex electronic systems (Annex 6), in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level. The concept level specifically requires consideration of interaction with other vehicle systems.

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:

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.
