Draft amendment to enable the approval of automated steering systems (e.g., lane-keeping/lane-changing assistance) for use at speeds above 10 km/h pursuant to discussions held during the 4th ACSF informal group session.

Summary of consensus reached during the 4th ACSF informal group session for a 4 second transition time under normal operating conditions and immediate warning under emergency conditions.

Amendment to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle, including specification of the connector through which electrical energy is supplied in the proposal

Proposal to consider a transition time between 2 and 4 seconds according to other variables (straight lane, curve, collision-imminent, lane change, etc.)

Presentation of results from Japan’s NTSEL research into the time required for the driver to transition from automated to manual steering modes and on driver/vehicle behavior throughout the transition period under various traffic scenarios.

Amendments to the Draft report of 3rd session referring to SE advice; adjustments in homework table.

Presentation on the concept of a minimum risk maneuver boundaries to define acceptable parameters for system-to-driver transition demands and system responses in cases of where the driver does not react.

Presentation proposing a requirement for defensive braking on vehicles equipped with ACSF because automated steering may result in driver inattention and therefore require compensating environment monitoring and automatic braking. This type of “protective braking” is viewed as a different order of braking than AEBS given that the principle involves maintaining of distances and avoiding accidents at speed rather than as an emergency or abrupt braking.

Comments on the draft amendment to UN R79 addressing automated steering as it stood at the end of the third ACSF informal group session. This document also raises links to rear vision (UN R46), AEBS (UN R131), and park assist systems.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

Progress report on the development of provisions for automatically commanded steering functions under UN Regulation No. 79.

Proposal to improve the wording of the draft amendment on lane-keeping assistance systems, based on document GRRF-79-04.

Input for the draft amendment to UN R79 to enable the type approval of automatically commanded steering functions for use at speeds above 10 km/h.

Proposal for modifications to document ACSF-02-03 submitted by Germany to enable the type approval of automated steering functions at speeds greater than 10 km/h.

Proposal for modifications to document ACSF-03-03 to enable the type approval of automated steering functions operating at speeds greater than 10 km/h.

Spreadsheet tool to calculate safety distances between vehicles as a function of speed and required braking distances.
