Proposal for revised transitional provisions under the regulation.

Proposal for corrections to the text and equations.

Proposal to allow Emergency Stop Signal (ESS) systems on motorcycles and related vehicles.

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.

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

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 introduce requirements for the approval of replacement brake lining assemblies for L-category vehicles.

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).

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.

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.

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 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 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.

Comments on the draft test procedures as described in the draft text of 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]”.
