Agenda item 9. (c) Automatically Commanded Steering Function (ACSF)

Proposed changes to the draft amendments to UN R79 concerning ACSF B1 systems. The proposed new wording for the triggering condition of the warning (“any front tyre of the vehicle is crossing the lane marking”) is technically more specific than the original (“the vehicle is going to leave the lane”). The use of a haptic signal as an alternative to the acoustic signal achieves the goal pursued by Germany. This proposal is consistent with the warning strategy of AEBS specified in UN R131. In the case of M2 M3 N2 N3 vehicle categories, it is proposed to take as a base the requirements specified in UN R130 LDWS regulation, which achieves the goal.

53. The expert from Germany introduced ECE/TRANS/WP.29/GRRF/2016/45, containing four options as possible ways forward to progress on ACSF. The Secretary of the IWG on Automatically Commanded Steering Function (ACSF) gave a presentation reporting on the progress made by the group (GRRF-82-17). He reported on definitions proposed for ACSF of Categories A to E, clarifications proposed for Corrective Steering Functions (CSF) and new provisions proposed for RCP. GRRF acknowledged the status report received and agreed to work on an amendment to Option 4 as proposed by GRRF-82-12. The proposal for Option 4 received several comments in GRRF-82-08, GRRF-82-09, GRRF-82-14, GRRF-82-15, GRRF-82-18, GRRF-82-19 and GRRF-82-26.
