Systems and methods for enhancing operator vigilance
System, methods, and other embodiments described herein relate to enhancing operator vigilance without causing an adverse reaction. In one embodiment, a method includes receiving a disengagement likelihood; selecting a stimulus pattern that if executed adjusts a vehicle function; and executing the stimulus pattern if the disengagement likelihood is above a first threshold and below a second threshold.
1 . A system for a vehicle, comprising:
a processor; and a memory storing machine-readable instructions that, when executed by the processor, cause the processor to:
receive a disengagement likelihood of an autonomous vehicle function ceasing operative control;
select a time-varying stimulus pattern that if executed adjusts a vehicle function;
execute the stimulus pattern if when the disengagement likelihood is within a numerical range bounded by a lower threshold and an upper threshold above which an alert is issued;
detect an action by the driver countering the stimulus pattern; and
adjust the stimulus pattern to avoid a repeat of the action.
2 . The system of claim 1 , wherein the machine-readable instructions further includes an instruction that, when executed by the processor, cause the processor to:
alter how the stimulus pattern adjusts the vehicle function if the disengagement likelihood changes.
3 . The system of claim 1 , wherein to adjust the stimulus pattern to avoid a repeat of the action only occurs when the action satisfies a relationship condition specified in the stimulus pattern.
4 . The system of claim 1 , wherein the machine-readable instructions further includes an instruction that, when executed by the processor, cause the processor to:
prohibit the execution of the stimulus pattern if a restriction condition exists.
5 . The system of claim 1 , wherein the vehicle function controls an actuator.
6 . The system of claim 1 , wherein the vehicle function controls climate functions.
7 . The system of claim 1 , wherein the the vehicle function affects physical window settings.
8 . The system of claim 1 , wherein the machine-readable instructions to select or execute the stimulus pattern occurs regardless of any estimates of an operator vigilance.
9 . A non-transitory computer-readable medium including instructions that when executed by one or more processors cause the one or more processors to:
receive a disengagement likelihood of an autonomous vehicle function ceasing operative control;
select a time-varying stimulus pattern that if executed adjusts a vehicle function;
execute the stimulus pattern if the disengagement likelihood is within a numerical range bounded by a lower threshold and an upper threshold above which an alert is issued;
detect an action by the driver countering the stimulus pattern; and
adjust the stimulus pattern to avoid a repeat of the action.
10 . The non-transitory computer-readable medium of claim 9 , wherein the instructions to execute the stimulus pattern further includes to alter how the stimulus pattern adjusts the vehicle function if the disengagement likelihood changes.
11 . The non-transitory computer-readable medium of claim 9 , wherein to adjust the stimulus pattern to avoid a repeat of the action only occurs when the action satisfies a relationship condition specified in the stimulus pattern.
12 . The non-transitory computer-readable medium of claim 9 , wherein the instructions to execute the stimulus pattern include instructions prohibiting the execution of the stimulus pattern if a restriction condition exists.
13 . The non-transitory computer-readable medium of claim 9 , wherein the vehicle function controls an actuator.
14 . A method for enhancing operator vigilance, the method comprising:
receiving a disengagement likelihood of an autonomous vehicle function ceasing operative control;
selecting a time-varying stimulus pattern that if executed adjusts a vehicle function;
executing the stimulus pattern if the disengagement likelihood is within a numerical range bounded by a lower threshold and an upper threshold above which an alert is issued;
detect an action by the driver countering the stimulus pattern; and
adjust the stimulus pattern to avoid a repeat of the action.
15 . The method of claim 14 , wherein executing the stimulus pattern includes altering how the stimulus pattern adjusts the vehicle function if the disengagement likelihood changes.
16 . The method of claim 14 , wherein to adjust the stimulus pattern to avoid a repeat of the action only occurs when the action satisfies a relationship condition specified in the stimulus pattern.
17 . The method of claim 14 , wherein executing the stimulus pattern includes prohibiting the execution of the stimulus pattern if a restriction condition exists.
18 . The method of claim 14 , wherein the vehicle function controls an actuator.
19 . The method of claim 14 , wherein the vehicle function controls climate functions.
20 . The method of claim 14 , wherein the vehicle function affects physical window settings.
