Proposal to amend the Introduction of the regulation to highlight technical issues related to the installation of AEBS on some specific vehicles included in the scope of the regulation.

Proposal to insert a new Introduction section to the regulation in order to highlight technical issues related to the installation of LDWS on some specific vehicles included in the scope of the regulation.

Proposal to establish a uniform CoP inspection questionnaire to harmonize conformity of production administrative requirements across Contracting Parties under UN R90. The intent is to increase efficiency and lower costs due to the absence of mutual recognition of CoP certifications among approval authorities.

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

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.

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.

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

Presentation highlighting the growing use of carbon-ceramic (CSiC) brake discs and the need to address these products under UN R90 given that the replacement discs regulation is founded upon conventional cast iron technologies.

Updated version of the proposal to remove tables specifying general values for replacement discs and drums that are identical to the original (2.3.3.4) since such replacements must by definition have values identical to the corresponding original parts. The proposal also would change the maximum permitted thickness variation of discs for medium and heavy vehicles from 0.030 mm to 0.050 mm (the common OEM specification). This revised proposal clarifies that the proposal would revise the specifications for vehicles of categories M3, N3, O3 and O4 but retain the maximum permitted specification of 0.030mm for vehicles of categories M2 and N2.

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

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

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.

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

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

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).

Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

Document GRRF/2016/20 proposes 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. Although this proposal was approved in principle at the 80th GRRF session, it was agreed that the proposal would be reviewed at the 81st GRRF to define an open value [X] in paragraph 2.1.1. of Annex 5. It has subsequently been concluded that this change to paragraph 2.1.1. is not needed. Therefore, this proposal removes the change to the paragraph from GRRF/2016/20.

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