Monitoring device, storage medium storing computer program for monitoring, and monitoring method
A monitoring device has a processor configured to determine a degree to which a driver is participating in driving, determine whether a merging terrain exists in which an adjacent lane vanishes by merging with the traveling lane, within a predetermined range from a current location of the vehicle, and alert the driver to be attentive to vehicle surroundings regardless of whether or not the merging terrain exists, when it has been determined that the degree to which the driver is participating in driving is low and speed of the vehicle exceeds a reference speed, or to alert the driver to be attentive to the vehicle surroundings only when it has been determined that the merging terrain exists, when it has been determined that the degree to which the driver is participating in driving is low and the speed of the vehicle does not exceed the reference speed.
1 . A monitoring device comprising:
a processor configured to
determine a degree to which a driver is participating in driving,
determine whether or not a merging terrain exists in which an adjacent lane that is adjacent to a traveling lane in which a vehicle is traveling vanishes by merging with the traveling lane, within a predetermined range from a current location of the vehicle in a traveling direction, and
alert the driver to be attentive to the vehicle surroundings only based on determining that the merging terrain exists, determining that the degree to which the driver is participating in driving is low, and a speed of the vehicle does not exceed a reference speed.
2 . The monitoring device according to claim 1 , wherein the processor is further configured to determine that the degree to which the driver is participating in driving is low when the driver is distracted or the driver feels drowsy.
3 . The monitoring device according to claim 2 , wherein the processor is further configured to
determine whether or not the driver is distracted using a determination scale for a direction in which the driver is gazing, and
change the determination scale based on the current location of the vehicle and the location of the merging terrain, when it has been determined that the merging terrain exists.
4 . The monitoring device according to claim 1 , wherein the reference speed is in a range of 10 kilometer/hour to 20 kilometer/hour.
5 . A computer-readable, non-transitory storage medium storing a computer program for monitoring, which causes a processor to execute a process, the process comprising:
determining a degree to which a driver is participating in driving;
determining whether or not a merging terrain exists in which an adjacent lane that is adjacent to a traveling lane in which a vehicle is traveling vanishes by merging with the traveling lane, within a predetermined range from a current location of the vehicle in a traveling direction; and
alerting the driver to be attentive to the vehicle surroundings based on determining that the merging terrain exists, determining that the degree to which the driver is participating in driving is low, and a speed of the vehicle does not exceed a reference speed.
6 . A monitoring method carried out by a driver monitoring device and the method comprises:
determining a degree to which a driver is participating in driving;
determining whether or not a merging terrain exists in which an adjacent lane that is adjacent to a traveling lane in which a vehicle is traveling vanishes by merging with the traveling lane, within a predetermined range from a current location of the vehicle in a traveling direction; and
alerting the driver to be attentive to the vehicle surroundings based on determining that the merging terrain exists, determining that the degree to which the driver is participating in driving is low, and a speed of the vehicle does not exceed a reference speed.
