Abstract

The present invention relates to a navigation system in which that navigation system shows a configuration of a complicated intersection a driver is about to enter, and displays where to turn and a progression rate of the car on the path the driver is headed to. The navigation system comprises a Gyro sensor for detecting a rotation angle of the car; and route information from the Gyro sensor to generate the configuration of an intersection the user is supposed to enter and an arrow indicating a driving route to the user, and to display a progression rate of the car along the route; a display driving unit for displaying the configuration of the intersection and the arrow for route guidance, and a gradual progression rate of the car is indicated in the directional arrow.

Claims

1. A vehicle navigation system, comprising:

a controller configured to generate a map of an intersection, to generate a first indication for indicating a suggested route for passing through the intersection, and to generate a second indication for indicating a location of the vehicle and for indicating a progression of the vehicle, the location of the vehicle being indicated by a shape of the second indication, the progression of the vehicle being indicated as the vehicle changes said location by changing the shape of the second indication; and

a display unit for displaying the first indication on the map of the intersection and for displaying the second indication, wherein the controller is configured to display the second indication by gradually changing the shape of the second indication according to the progression of the vehicle.

2. The system according to claim 1, wherein the controller is configured to display the second indication in the first indication.

3. The system according to claim 2, wherein the controller is configured to display the second indication in the first indication according to the progression of the vehicle by gradually filling the first indication with color.

4. The system according to claim 2, wherein the controller is configured to display the second indication in the first indication according to the progression of the vehicle by gradually removing color from the first indication.

5. A vehicle navigation system, comprising:

a controller configured to generate a map of an intersection and to generate a first indication for indicating a suggested route passing through the intersection; and

a display unit configured to display the first indication on the map of the intersection and to display a second indication on the first indication, the second indication for indicating a location of a vehicle in the map of the intersection, wherein the controller is configured to display the second indication by gradually filling the first indication with color.

6. A vehicle navigation system, comprising:

a controller configured to generate a map of an intersection and to generate a first indication for indicating a suggested route passing through the intersection; and

a display unit configured to display the first indication on the map of the intersection and to display a second indication on the first indication, the second indication for indicating a location of a vehicle in the map of the intersection, wherein the controller is configured to display the second indication by gradually removing color from the first indication.

7. A vehicle navigation system, comprising:

a GPS unit configured to detect a location of a vehicle based on information from at least one GPS satellite;

a controller configured to generate a map of an intersection that the vehicle approaches and to generate a first indication for indicating a suggested route for approaching and for departing the intersection; and

a display unit configured to display the first indication on the map of the intersection and to display a second indication on the first indication, the second indication for indicating the location of the vehicle and for indicating a progression of the vehicle, wherein the controller is configured to gradually change a shape of the second indication according to the progression of a vehicle.

8. A vehicle navigation system, comprising:

a controller configured to generate a map and to generate a first indication for indicating a suggested route passing through an intersection included in the map; and

a display configured to display the first indication on the map and to display a second indication on the first indication, the second indication for indicating a location of a vehicle in the intersection, wherein the controller is configured to change a shape of the second indication according to a progression of the vehicle.

9. The vehicle navigation system according to claim 8, wherein the first indication is an arrow for indicating the suggested route.

10. The vehicle navigation system according to claim 8, wherein the controller is configured to gradually change the shape of the second indication.

11. The vehicle navigation system according to claim 10, wherein the controller is configured to gradually change the shape of the second indication from nothing into a shape of the first indication.

12. The vehicle navigation system according to claim 10, wherein the controller is configured to gradually change the shape of the second indication from a shape of the first indication into nothing.

13. A vehicle navigation system, comprising:

a GPS unit configured to detect a location of a vehicle based on information from at least one GPS satellite;

a controller configured to generate a map of an intersection that the vehicle approaches and to generate a first indication for indicating a suggested route for approaching and for departing the intersection; and

a display unit configured to display the first indication on the map of the intersection and to display a second indication in the first indication, the second indication for indicating the location of the vehicle and for indicating a progression of the vehicle, wherein the controller is configured to display the second indication in the first indication according to the progression of the vehicle by gradually filling the first indication with color.

14. A vehicle navigation system, comprising:

a GPS unit configured to detect a location of a vehicle based on information from at least one GPS satellite;

a controller configured to generate a map of an intersection that the vehicle approaches and to generate a first indication for indicating a suggested route for approaching and for departing the intersection; and

a display unit configured to display the first indication on the map of the intersection and to display a second indication in the first indication, the second indication for indicating the location of the vehicle and for indicating a progression of the vehicle, wherein the controller is configured to display the second indication in the first indication according to the progression of a vehicle by gradually removing color from the first indication.
