Abstract
Various examples are directed to systems and methods for operating an autonomous vehicle. A vehicle system may configure an alertness monitor to send an alert prompt to a cockpit output device in response to not detecting a user input for an input threshold time. The vehicle system may detect an alertness condition change based at least in part on vehicle data describing the vehicle. In response to detecting the alertness condition change, the vehicle system may modify an alertness system parameter.
Claims20
An autonomous vehicle alertness monitor system, comprising:
- a cockpit output device to provide alert prompts to a user of an autonomous vehicle;
- a cockpit input device to receive inputs from the user of the autonomous vehicle;
- and
- at least one hardware processor unit programmed to perform operations comprising:
- sending an alert prompt to the cockpit output device in response to not detecting a user input from the user of the autonomous vehicle for an input threshold time, the sending based at least in part on an alertness monitor system parameter;
- detecting a change in a condition of the autonomous vehicle using vehicle data describing the autonomous vehicle;
- and
- in response to detecting the change in the condition of the autonomous vehicle, modifying the alertness monitor system parameter.
A method of operating an autonomous vehicle, comprising:
- sending an alert prompt to a cockpit output device in response to not detecting a user input from the user of the autonomous vehicle for an input threshold time, the sending based at least in part on an alertness monitor system parameter;
- detecting a change in a condition of the autonomous vehicle using vehicle data describing the autonomous vehicle;
- and
- in response to detecting the change in the condition of the autonomous vehicle, modifying the alertness monitor system parameter.
A non-transitory machine-readable medium comprising instructions thereon that, when executed by a processor unit, cause the processor unit to execute operations comprising:
- sending an alert prompt to a cockpit output device in response to not detecting a user input from the user of an autonomous vehicle for an input threshold time, the sending based at least in part on an alertness monitor system parameter;
- detecting a change in a condition of the autonomous vehicle using vehicle data describing the autonomous vehicle;
- and
- in response to detecting the change in the condition of the autonomous vehicle, modifying the alertness monitor system parameter.
