Driving support device, method, and computer program for supporting driving
View Patent ↗A driving support device includes a processor configured to detect a sign of sleepiness of a driver of a vehicle, based on a driver image representing the driver's head generated by a driver monitoring camera configured to take a picture of the driver's head, determine a response request to the driver, depending on environment around the vehicle or a travel condition of the vehicle, when a sign of the driver's sleepiness is detected, and notify the driver of the response request via a user interface provided in the vehicle.
1 . A driving support device comprising:
a processor configured to:
detect a sign of sleepiness of a driver of a vehicle, based on a driver image representing the driver's head generated by a driver monitoring camera configured to take a picture of the driver's head,
detect a predetermined feature in an area around the vehicle as one representing an environment around the vehicle,
determine a response request to the driver related to information represented on the detected predetermined feature as the response request, when a sign of the driver's sleepiness is detected,
notify the driver of the response request via a user interface provided in the vehicle;
determine whether the driver has made a response requested in the response request after notification of the response request, and
control the vehicle so as to stop the vehicle when the driver has not made the response even after a predetermined period from notification of the response request.
2 . The driving support device according to claim 1 , wherein when a sign of the driver's sleepiness is detected, the processor detects an action of the vehicle as the travel condition and determines a request for a response related to the detected action of the vehicle as the response request.
3 . The driving support device according to claim 1 , wherein the processor determines the response request, depending on the level of autonomous driving control applied to the vehicle.
4 . The driving support device according to claim 1 , wherein the processor determines the level of the driver's sleepiness, and
the processor determines the response request so that a more complicated response is requested as the level of the driver's sleepiness is higher.
5 . A method for supporting driving, comprising:
detecting a sign of sleepiness of a driver of a vehicle, based on a driver image representing the driver's head generated by a driver monitoring camera configured to take a picture of the driver's head;
detecting a predetermined feature in an area around the vehicle as one representing an environment around the vehicle;
determining a response request to the driver related to information represented on the detected predetermined feature as the response request, when a sign of the driver's sleepiness is detected;
notifying the driver of the response request via a user interface provided in the vehicle;
determining whether the driver has made a response requested in the response request after notification of the response request, and
controlling the vehicle so as to stop the vehicle when the driver has not made the response even after a predetermined period from notification of the response request.
6 . A non-transitory recording medium that stores a computer program for supporting driving, the computer program causing a processor mounted on a vehicle to execute a process comprising:
detecting a sign of sleepiness of a driver of the vehicle, based on a driver image representing the driver's head generated by a driver monitoring camera configured to take a picture of the driver's head;
detecting a predetermined feature in an area around the vehicle as one representing an environment around the vehicle;
determining a response request to the driver related to information represented on the detected predetermined feature as the response request, when a sign of the driver's sleepiness is detected;
notifying the driver of the response request via a user interface provided in the vehicle;
determining whether the driver has made a response requested in the response request after notification of the response request, and
controlling the vehicle so as to stop the vehicle when the driver has not made the response even after a predetermined period from notification of the response request.
