Abstract

A notification system includes: a first extraction unit configured to extract caution-required locations present within a predetermined distance range centered on a current position of a vehicle from a plurality of caution-required locations of which the positional information is previously acquired; a second extraction unit configured to extract caution-required locations present within a predetermined angle centered on a current traveling direction of the vehicle from the plurality of caution-required locations; a third extraction unit configured to extract, as a notification target point, a caution-required location where the current position of the vehicle is present within a predetermined angle range centered on the orientation of a link through which the vehicle is determined to pass by referring to map data holding information of a plurality of links in which positions and orientations are matched with each other, from caution-required locations extracted in common by both the first extraction unit and the second extraction unit; and an execution unit configured to execute a caution-required location traveling notification in accordance with the approach of the vehicle to the notification target point extracted by the third extraction unit.

Claims

1. A notification system comprising:

a first extraction unit configured to extract caution-required locations present within a predetermined distance range centered on a current position of a vehicle from a plurality of caution-required locations of which the positional information is previously acquired;

a second extraction unit configured to extract caution-required locations present within a predetermined angle centered on a current traveling direction of the vehicle from the plurality of caution-required locations;

a third extraction unit configured to extract, as a notification target point, a caution-required location where the current position of the vehicle is present within a predetermined angle range centered on the orientation of a link through which the vehicle is determined to pass by referring to map data holding information of a plurality of links in which positions and orientations are matched with each other, from caution-required locations extracted in common by both the first extraction unit and the second extraction unit; and

an execution unit configured to execute a caution-required location traveling notification in accordance with the approach of the vehicle to the notification target point extracted by the third extraction unit.

2. The notification system according to claim 1,

wherein a target speed, which is calculated for each of the caution-required locations and each of the links and becomes a target for safely passing through a caution-required location is included in the information of the plurality of links,

wherein the notification system further comprises:

a distance determination unit configured to determine whether or not the distance between the current position of the vehicle and the notification target point is within a predetermined distance;

a measurement unit configured to measure a traveling speed of the vehicle;

a speed determination unit configured to compare the traveling speed of the vehicle measured by the measurement unit and the target speed of the link of the caution-required location;

a first time determination unit configured to determine whether or not the vehicle reaches the notification target point from the current position of the vehicle within a first time threshold when the vehicle travels at the traveling speed measured by the measurement unit; and

a second time determination unit configured to determine whether or not the vehicle reaches the notification target point from the current position of the vehicle within a second time threshold when the vehicle travels at the traveling speed measured by the measurement unit, and

wherein the execution unit executes the caution-required location traveling notification in the notification target point, on the basis of determination results of the distance determination unit, the speed determination unit, the first time determination unit, and the second time determination unit.

3. The notification system according to claim 1,

wherein the execution unit provides an operation allowable angle range where the caution-required location traveling notification is allowed to be executed around the orientation of the notification target point and executes the caution-required location traveling notification when the current position of the vehicle is present within the operation allowable angle range.

4. The notification system according to claim 1,

wherein the execution unit does not execute the caution-required location traveling notification when a minimum speed of the vehicle within a past predetermined period of time exceeds a given speed.

5. The notification system according to claim 1,

wherein the caution-required location is a caution-required location where a caution is predicted and determined to be required when a vehicle passes through a certain point, on the basis of the traveling history of a plurality of vehicles that is previously generated.

6. An electronic device comprising:

a first extraction unit configured to extract caution-required locations present within a predetermined distance range centered on a current position of a vehicle from a plurality of caution-required locations of which the positional information is previously acquired;

a second extraction unit configured to extract caution-required locations present within a predetermined angle centered on a current traveling direction of the vehicle from the plurality of caution-required locations;

a third extraction unit configured to extract a caution-required location where the current position of the vehicle is present within a predetermined angle range centered on the orientation of a link through which the vehicle is determined to pass by referring to map data holding information of a plurality of links in which positions and orientations are matched with each other, from caution-required locations extracted in common by both the first extraction unit and the second extraction unit; and

an execution unit configured to execute a caution-required location traveling notification in accordance with the approach of the vehicle to the caution-required location extracted by the third extraction unit.

7. A notification method comprising:

a first process, executed by a first extraction unit, of extracting caution-required locations present within a predetermined distance range centered on a current position of a vehicle from a plurality of caution-required locations of which the positional information is previously acquired;

a second process, executed by a second extraction unit, of extracting caution-required locations present within a predetermined angle centered on a current traveling direction of the vehicle from the plurality of caution-required locations;

a third process, executed by a third extraction unit, of extracting a caution-required location where the current position of the vehicle is present within a predetermined angle range centered on the orientation of a link through which the vehicle is determined to pass by referring to map data holding information of a plurality of links in which positions and orientations are matched with each other, from caution-required locations extracted in common by both the first process and the second process; and

a fourth process of executing a caution-required location traveling notification in accordance with the approach of the vehicle to the caution-required location extracted in the third process.

8. A non-transitory computer readable medium storing a program when executed causes a computer to execute:

a first step of extracting caution-required locations present within a predetermined distance range centered on a current position of a vehicle from a plurality of caution-required locations of which the positional information is previously acquired;

a second step of extracting caution-required locations present within a predetermined angle centered on a current traveling direction of the vehicle from the plurality of caution-required locations;

a third step of extracting a caution-required location where the current position of the vehicle is present within a predetermined angle range centered on the orientation of a link through which the vehicle is determined to pass by referring to map data holding information of a plurality of links in which positions and orientations are matched with each other, from caution-required locations extracted in common by both the first step and the second step; and

a fourth step of executing a caution-required location traveling notification in accordance with the approach of the vehicle to the caution-required location extracted in the third step.
