Abstract

A navigation terminal for a vehicle includes: a boundary information acquisition unit acquiring at least one piece of boundary information, representing a boundary of a geo-fence, on a map; a path search unit searching for progress paths between a current position of the vehicle displayed on the map and the at least one piece of boundary information; a cross point calculation unit calculating a road cross point on at least one identified progress path, connected to the at least one piece of boundary information, based on a degree of proximity of the at least one identified progress path to the at least one piece of boundary information; and a warning issue unit outputting a warning when it is sensed that the vehicle is approaching the calculated road cross point.

Claims

1. A navigation terminal for a vehicle comprising:

a boundary information acquisition unit acquiring at least one piece of boundary information, representing a boundary of a geo-fence, on a map;

a path search unit searching for progress paths between a current position of the vehicle displayed on the map and extracted road boundary information among the at least one piece of boundary information having a highest priority of proximity to the current position of the vehicle;

a cross point calculation unit calculating a road cross point on at least one identified progress path, connected to the at least one piece of boundary information, based on a degree of proximity of the at least one identified progress path to the at least one piece of boundary information; and

a warning issue unit outputting a warning when it is sensed that the vehicle is approaching the calculated road cross point, wherein

the warning is a preliminary warning that is issued before the vehicle deviates from the boundary of the geo-fence, and

the at least one piece of boundary information is located on a road connected directly to the current position of the vehicle.

2. The navigation terminal according to claim 1, wherein the boundary information includes road boundary information passing through boundary points of the geo-fence and geographical boundary information neighboring the road boundary information.

3. The navigation terminal according to claim 2, wherein the boundary information acquisition unit includes:

a boundary information storage unit storing the boundary information including the road boundary information and the geographical boundary information; and

a boundary information extraction unit extracting the road boundary information from the stored boundary information and outputting the extracted road boundary information to the path search unit.

4. The navigation terminal according to claim 1, wherein the cross point calculation unit calculates a first road cross point extending inwardly from the road boundary information.

5. The navigation terminal according to claim 4, wherein when a distance between the current position of the vehicle and the road cross point is within a predetermined distance range, the warning issue unit determines that a risk state exists and outputs the warning.

6. The navigation terminal according to claim 5, wherein the warning includes a message warning displayed on a road, on which the vehicle travels, on the map or a voice warning outputted through a speaker of the vehicle.

7. The navigation terminal according to claim 1, wherein each of the boundary information, the current position of the vehicle, and the road cross point includes coordinate values including latitude and longitude.

8. A navigation terminal for a vehicle comprising:

a memory configured to store at least one program; and

a processor configured to execute the at least one stored program,

wherein when the processor executes the at least one stored program, the processor;

acquires at least one piece of boundary information, representing a boundary of a geo-fence, on a map,

searches for progress paths between a current position of the vehicle displayed on the map and extracted road boundary information among the at least one piece of boundary information having a highest priority of proximity to the current position of the vehicle,

calculates a road cross point on at least one identified progress path, connected to the at least one piece of boundary information, based on a degree of proximity of the at least one identified progress path to the at least one piece of boundary information, and

outputs a warning when it is sensed that the vehicle is approaching the calculated road cross point, and wherein

the warning is a preliminary warning that is issued before the vehicle deviates from the boundary of the geo-fence, and

the at least one piece of boundary information is located on a road connected directly to the current position of the vehicle.

9. A navigation server comprising:

an information reception unit receiving at least one piece of boundary information, representing a boundary of a geo-fence, from a navigation terminal and receiving a current position of a vehicle from a global positioning system (GPS);

a path search unit searching for progress paths between the current position of the vehicle displayed on a map and extracted road boundary information among the at least one piece of boundary information having a highest priority of proximity to the current position of the vehicle;

a cross point calculation unit calculating a road cross point on at least one identified progress path, connected to the at least one piece of boundary information, based on a degree of proximity of the at least one identified progress path to the at least one piece of boundary information;

a warning generation unit generating warning information when it is sensed that the vehicle is approaching the calculated road cross point; and

an information transmission unit transmitting the at least one piece of boundary information, the current position of the vehicle, the at least one identified progress path, and the calculated road cross point to the navigation terminal in real-time by applying the at least one piece of boundary information, the current position of the vehicle, the at least one identified progress path, and the calculated road cross point to the map, and transmitting the generated warning information to the navigation terminal, wherein

the warning information includes a preliminary warning that is issued before the vehicle deviates from the boundary of the geo-fence, and

the at least one piece of boundary information is located on a road connected directly to the current position of the vehicle.

10. The navigation server according to claim 9, wherein the boundary information includes road boundary information passing through boundary points of the geo-fence and geographical boundary information neighboring the road boundary information.

11. The navigation server according to claim 10, wherein the cross point calculation unit calculates a first road cross point extending inwardly from the road boundary information.

12. The navigation server according to claim 11, wherein when a distance between the current position of the vehicle and the road cross point is within a predetermined distance range, the warning generation unit determines that a risk state exists and generates the warning.
