186.760 Definitions for KRS 186.760 to 186.779.
As used in KRS 186.760 to 186.779:
(1) "Automated driving system" means hardware and software that are collectively
capable of performing the entire dynamic driving task on a sustained basis,
regardless of whether it is limited to a specific operational design domain;
(2) "Dynamic driving task" or "DDT":
(a) Means all of the real-time operational and tactical functions required to
operate a vehicle in on-road traffic, including without limitation:
1.
Lateral vehicle motion control via steering;
2.
Longitudinal motion control via acceleration and deceleration;
3.
Monitoring the driving environment via object and event detection,
recognition, classification, and response preparation;
4.
Object and event response execution;
5.
Maneuver planning; and
6.
Enhancing conspicuity via lighting, signaling, and gesturing; and
(b) Does not include strategic functions such as trip scheduling and the selection
of destinations and waypoints;
(3) "DDT fallback" means the response by:
(a) The person or human driver to either perform the DDT or achieve a minimal
risk condition after occurrence of a DDT performance relevant system failure,
or upon operational design domain exit; or
(b) An automated driving system to achieve minimal risk condition, given the
same circumstances identified in paragraph (a) of this subsection;
(4) "Fully autonomous vehicle" means a motor vehicle equipped with an automated
driving system designed to function without a human driver as a level 4 or 5 system
under SAE J3016;
(5) "Human driver" means a natural person in the vehicle with a valid license to operate
a motor vehicle who controls all or part of the dynamic driving task;
(6) "Minimal risk condition" means a condition to which a person, human driver, or an
automated driving system may bring a vehicle after performing the DDT fallback in
order to reduce the risk of a crash when a given trip cannot or should not be
completed;
(7) "Operational design domain" or "ODD" means the operating conditions under which
a given automated driving system is specifically designed to function, including but
not limited to:
(a) Environmental, geographical, and time-of-day restrictions; and
(b) The requisite presence or absence of certain traffic and roadway
characteristics;
(8) "Public agency" has the same meaning as in KRS 61.870;
(9) "Request to intervene" means a notification by an automated driving system to a
human driver that the human driver should promptly begin or resume performance
of part or all of the dynamic driving task; and
(10) "SAE J3016" means the "Taxonomy and Definitions for Terms Related to Driving
Automation Systems for On-Road Motor Vehicles" published by SAE International
on June 15, 2018, as amended.
