Abstract

A vehicle navigation system and navigation method thereof are disclosed. The vehicle navigation system comprises a location detector to acquire a current location of a vehicle, a calculation unit to calculate a navigation route from a departure location to a destination, a database including map data and a plurality of restrictions associated with restricted sites on the map data, the calculation unit calculates a navigation route from the departure location to the destination based on the map data and the plurality of restrictions. Thus, the vehicle navigation system may provide the navigation route excluding sites with possible restriction applied thereto.

Claims

1. A computer-implemented method for navigation applied in a vehicle navigation system, the vehicle navigation system comprises a database including map data and a plurality of restrictions associated with restricted sites on the map data, the method comprising:

determining a departure location and a destination of a vehicle;

determining a departure time of the vehicle;

estimating a driving speed of the vehicle;

estimating an arrival time at each midway point between the departure location and the destination based on the driving speed; and

calculating a navigation route from the departure location to the destination based on the map data, the plurality of restrictions stored in the database, the departure time and the arrival time.

2. The method of claim 1, wherein calculation of the navigation route further comprising:

calculating a base route from the departure location to the destination based on the map data;

determining whether the base route comprises the restricted sites;

determining whether the arrival time for any midway points located at the restricted sites matches restriction times for the restricted sites;

calculating a navigation route excluding the restricted sites from the departure location to the destination when the arrival time matches the restriction times for the restricted sites.

3. The method of claim 2, wherein the origin location is a current location of the vehicle.

4. The method of claim 2, wherein the departure location is determined by user input.

5. The method of claim 2, wherein the plurality of restrictions is determined according to official regulations.

6. The system of claim 2, wherein the plurality of restrictions is determined by user input.

7. A vehicle navigation system comprising:

a location detector to acquire a current location of a vehicle;

a calculation unit to calculate a navigation route from a departure location to a destination, to determine a departure time and to estimate an arrival time for each midway point between the departure location and the destination;

a database including map data and a plurality of restrictions associated with restricted sites on the map data; and

wherein the calculation unit calculates the navigation route from the departure location to the destination based on the map data, the plurality of restrictions stored in the database, the departure time and the arrival time.

8. The system of claim 7, wherein the calculation unit further calculates a base route from the departure location to the destination based on the map data.

9. The system of claim 8, wherein the departure location is the current location of the vehicle.

10. The system of claim 8, wherein the departure location is determined by user input.

11. The system of claim 7, wherein the plurality of restrictions for restricted sites is determined according to official regulations.

12. The system of claim 7, wherein the plurality of restrictions for restricted sites is determined by user input.

13. A storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform a navigation method applied in a vehicle navigation system, the vehicle navigation system comprises a database including map data and a plurality of restrictions associated with restricted sites on the map data, the method comprising:

determine a departure location and a destination of a vehicle;

determine a departure time of the vehicle;

estimate a driving speed of the vehicle;

estimate an arrival time at each midway point between the departure location and the destination based on the driving speed; and

calculate a navigation route from the departure location to the destination based on the map data, the plurality of restrictions stored in the database, the departure time and the arrival time.

14. The storage medium of claim 13, wherein calculation of the navigation route further comprises:

calculate a base route from the departure location to the destination based on the map data;

determine whether the base route comprises the restricted sites;

determine whether the arrival time for any midway points located at the restricted sites matches restriction times for the restricted sites;

calculate a navigation route excluding the restricted sites from the departure location to the destination when the arrival time matches the restriction times for the restricted sites.

15. The storage medium of claim 14, wherein the origin location is a current location of the vehicle.

16. The storage medium of claim 14, wherein the departure location is determined by user input.

17. The storage medium of claim 14, wherein the plurality of restrictions is determined according to official regulations.

18. The storage medium of claim 14, wherein the plurality of restrictions is determined by user input.
