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.
