Working draft from the ACSF informal group to enable the approval of driver-initiated automated lane-change systems under UN R79.

Category G vehicles (defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3)) have specific characteristics that enable them to achieve traction on, and to traverse over, off-road terrain that would defeat and/or damage conventional road vehicles. In some situations, it would be safer for the driver to be able to manoeuvre the vehicle from outside. This proposal seeks to permit remote manoeuvring capability provided that the vehicle is designed to operate in this environment and the off-road location is confirmed throughout the whole period that the function is in use.

Proposal for extend the current mandate of the informal group until September 2018.

This proposal supplements proposal GRRF/2017/23 which amends UN R13, R13H and R140, to allow the use of the ESC tell-tale to indicate the intervention on the steering angle of one or more wheels for the purpose of vehicle stability. The intention allow design options that avoid two optical warning signals (ESC flashing + constant CSF) during an ESC intervention.

Draft proposal to enable the approval of automated emergency steering systems intended to avoid or mitigate collisions. The proposal based on document ACSF-14-07 submitted by OICA and CLEPA which was discussed during the 14th meeting of the ACSF informal group. The square brackets indicates paragraphs which are still under discussion in the informal group.

Comments submitted to GRRF through the secretariat proposing amendments to the draft text on automated lane-change systems.

Proposal to allow adaptation of speed and distance calculations in accordance with national speed limits since some nations enforce maximum speed limits below the 130 km/h used as the basis for the proposals on automated lane-change systems. Japan expects to refine the proposal in order to address mutual recognition concerns inherent in such recourse to national requirements. Japan further proposes clarification of the approaching vehicle (motorcycle) test target pending development of uniform test target specifications.

Set of diagrams illustrating the phases and timing of the test procedure for an automated lane-change maneuver as envisioned by the draft amendment to introduce Category C¹ ACSF into UN R79. These figures include the vehicle under test and approaching motorcycle speeds and distances under the lane-change phases, including timing and duration of each phase.

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.

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.
