Consolidated draft for the approval of automated steering systems pursuant to the discussions and decisions of the 5th ACSF informal group session (January 2016).

Updated list of functions/capabilities per ACSF category, including B1 and B2 categories addressing “hands-on” and “hands-off” lane-keeping.

Test procedure application for advanced systems of category D depending upon the steering configuration per category B (B1:hands-on with detection system steering, B2: hands-off enabled steering).

OICA presentation on approaches and trade-offs in handling driver availability for transitions between automated vehicle system and human driver.

Table of requirements for automatically commanded steering function capabilities (e.g., hazard warning activation, driver alerts, minimum risk maneuvers, etc.) according the ACSF category.

Schematic flow of events and responses for automatically commanded steering functions, including transition demands and fall-back on minimum risk maneuvers by the system.

OICA and CLEPA note that the current work on ACSF does not address class O vehicles (trailers) and therefore leaves unsettled the issue of heavy-duty commercial vehicles. The two groups signal that the informal group must coordinate with the GRRF to ensure that trailers are eventually incorporated in the ACSF approval procedures under UN R79.

Proposed changes to the working draft text ACSF-04-20.

Overview of proposed test modes/procedures for Category E automatically commanded steering systems.

Presentation on paragraph 5.6.1.4 of the draft amendment to UN R79 intended to enable the approval of automatically controlled steering functions at speeds above 10 km/h. This paragraph concerns transitions between the human driver and the automated steering system.

Proposal to define and require countermeasures to ensure that a driver remains available to assume control of a vehicle from an automated lane-keeping/steering system as conditions warrant. This document proposes definitions for a “driver attention recognition [system/function]” and/or a “driver attention confirmation [system/function]”.

Comments on the draft test procedures as described in the draft text of document ACSF-04-20.

Updated version of the draft text under development within the ACSF informal group, based upon the previous version in document ACSF-04-20.
