Information document submitted by the informal group on Complex Electronic Systems concerning work on clarifying Annex 6 of UN R79, especially with regard to the assessment of automated steering systems. A revision to paper, based upon a further meeting of the informal group, will be provided to GRRF-84. Please note that the phrase “Amend paragraph 5.1.10., to read:” should read “Amend paragraph 5.1.11”.

Draft amendment to UN R79, including provisions for emergency steering functions (ESF), Category C[1] ACSF for lane-change maneuvers, and updating of Complex Electronic Systems (CEL) Annex 6 provisions. This document was prepared during the 84th GRRF session for consideration during the special 85th GRRF scheduled to finalize a proposal for automated lane-change systems.

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF).

Revised proposal, as approved during the 84th GRRF session, to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.
