Informal Document GRVA-05-09/Rev.1

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 stipulate that “Automatic deactivation by the system of the direction indicator is required only if the lane change manoeuvre is initiated automatically, or if the direction indicator control is not fully engaged (latched position) during the lane change manoeuvre.”
