Changes and notes made to the ACSF informal group status report as part of the GRRF discussion on how to deliver approval requirements for ACSF B2 (lane-keeping at Level 3 automation) within the prescribed mandate of the group. The ACSF group is expect to deliver a draft text within the next nine months.

Norwegian request for GRRF comments on protection of steering gear and attachment to heavy vehicle frames. In a collision in Norway, the steering gear detached from the vehicle frame following a frontal collision such that the driver could no longer control the vehicle. Norway seeks input on strengthening the protection of steering gear in order to avoid such a situation.

Proposal of amendments to the proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems, defined as driver-actuated systems on off-road vehicles used for navigating exceptionally difficult terrain. OICA seeks to cover remote control applications for low speed manoeuvring not addressed in the original UK proposal.

Proposal from Germany and the Republic of Korea to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

Draft proposal for automated lane-changes systems including maneuver initiation (activation of direction indicator) and a second deliberate action of the driver (two-step HMI).

Discussion presentation especially concerning the regulation of lane-keeping systems corresponding to SAE Level 3 automation criteria (vehicle under system control with human driver as fallback).

OICA input regarding variations in driver responses to system requests to take over control of the vehicle and the implications for system transition requirements.

Draft proposal from OICA and CLEPA to include provisions for lane-change systems involving a second deliberate action of the driver to initiate a system-assisted lane change, including blind spot detection to avoid collisions. OICA and CLEPA wish to have provisions for such Category C2 systems included in UN R79.

Vehicle and supplier industry perspectives on addressing lane-keeping and lane-change systems within the context of Level 3 and higher automation. Current automated steering provisions adopted under UN R79 implicitly refer to Level 2 automation where the driver is required to maintain constant engagement whereas higher levels of automation would enable the driver to engage in secondary tasks.

OICA discussion of lane-keeping systems (ACSF B2) in terms of the level of automation where Level 2 requires constant driver supervision of the system and engagement with the vehicle operating environment and Level 3 places the operation of the vehicle entirely under the control of the automated system with the human driver as a fallback option in the event the system detects conditions beyond its operational boundaries. OICA is concerned to ensure that B2 systems will be permitted under both levels of automation.

OICA proposal concerning specifications for Category C2 automated steering systems where a vehicle system assists the driver in effecting a lane change after the driver activates the turn signal and initiates the maneuver through a second deliberate action (under C1, the driver activates the turn signal and automated lane-change system to effect the maneuver automatically).

Proposal to introduce provisions for driver-initiated automated lane-change systems (Category C ASCF) and for automated emergency steering functions (ESF). This proposal includes amendments the annex on complex electronic systems (Annex 6), in particular, to require auditing of the methodologies used to ensure system safety at both concept and system level. The concept level specifically requires consideration of interaction with other vehicle systems.

Proposal to allow the use of the flashing electronic stability control (ESC) tell-tale to indicate the intervention of a corrective steering function (CSF) in cases where the CSF is controlled by the ESC (or other vehicle stability function) system. Outside such cases, CSF interventions are indicated by a continuous optical signal displayed for the duration of the intervention.
