Abstract
A vehicle includes an automated driving assistance system that controls maneuvering of the vehicle under certain conditions. When the vehicle comes to a stop, the driving assistance system dynamically selects a threshold stop time corresponding to a duration of time that the vehicle can remain stopped before the driving assistance system will either detect a physical action from the user to resume automated driving assistance or time out and cease the driving assistance.
Claims20
A method, comprising:
- providing, with a driving assist system of a vehicle, automated driving assistance to a driver of the vehicle;
- monitoring one or more attention indicators of the driver;
- generating a map of a current location of the vehicle;
- selecting, with the driving assist system, a threshold stop time based on the one or more attention indicators and a resolution of the map of the current location;
- and
- resuming automated driving assistance responsive to detecting engagement of a mechanism by the driver if the vehicle has been stopped longer than the threshold stop time.
3 more elements
A vehicle, comprising:
- one or more cameras configured to capture images of a driver;
- a driver attention analysis system configured to analyze the images and to monitor attention indicators of the driver based on the images;
- a map system configured to store a map of a current location;
- and
- a driving assist system configured to provide automated driving assistance and to select a threshold stop time to resume automated driving assistance after a stop based on a resolution of the map and the attention indicators.
