Research plan for ACPE vehicle performance. Tests using actual vehicles will evaluate ACPE performance of vehicles on the Japanese market. Tests specified in UN R175 01 series will be conducted, along with tests under extended conditions with partially expanded test parameters. Test procedure for creeping vehicle specified in UN R175 01 series, paragraph 6.6.2, will be conducted. Activation limits of ACPE will be confirmed using distance to target and pedal application speed as test parameters. Tests will use one 2026 model year Suzuki Swift and one 2026 model year Daihatsu Move. Vehicle procurement by end of September, testing late October to November, data analysis by end of December, summary of research results early January.

Proposal for modifications to document ACSF-02-03 submitted by Germany to enable the type approval of automated steering functions at speeds greater than 10 km/h.

Proposal for modifications to document ACSF-03-03 to enable the type approval of automated steering functions operating at speeds greater than 10 km/h.

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.)

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

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.

NTSEL study into the effect of automated steering on the level of driver alertness. The data suggests an increase in drowsiness as measured by blinking/eyelid closing rates.

Breakdown of the requirements of the draft consolidated amendment (ACSF-06-28) for each category of ACSF.

Table of ACSF categories as defined by functions and requirements of the draft amendment to UN R79.

Consideration of the borderline in distinguishing between corrective steering functions and automatically commanded steering functions towards defining requirements for the approval of automated steering systems.
