Abstract

A vehicle-mounted navigation device comprises an image display means which performs guiding of a direction of travel only by display of an arrow when a vehicle is running on a guided route and which performs map display instead of said arrow display when said vehicle is off the guided route.

Claims

1. A vehicle-mounted navigation device comprising:

a memory means for storing map data and arrow data;

a position measuring means for measuring a present position of a vehicle;

a calculation means and an image display means for calculating a guided route from the present position to a destination and for selecting the displaying of said guided route from the present position to a destination and for selecting the displaying of said guided route on a map read out from said memory means and displaying an arrow indicating a direction of travel of the vehicle wherein the arrow can indicate the direction of travel with a map background and without a map background; and

said image display means for displaying the selected display contents, wherein said image display means displays the arrow indicating the direction of travel of the vehicle under normal condition and performs map display for a predetermined period of time in response to an input operation by a user.

2. A vehicle-mounted navigation device according to claim 1, wherein said image display means displays the arrow indicating the direction of travel of the vehicle under normal condition and performs map display when the vehicle is running off the guided route.

3. A vehicle-mounted navigation device according to claim 1, wherein said image display means displays the arrow indicating the direction of travel of the vehicle under normal condition and performs map display when setting the destination.

4. A vehicle-mounted navigation device according to claim 1, wherein said image display means displays the arrow indicating the direction of travel of the vehicle under normal condition and performs map display when the vehicle is positioned near the destination.

5. A vehicle-mounted navigation device comprising:

a display;

a memory;

a position sensor; and

a processor coupled to the display, the memory, and the position sensor, the memory storing map data and arrow data, the processor configured to calculate a guided route from a present position to a destination;

select for presentation on the display one of the guided routes on a map read from the memory, and an arrow indicating a direction of travel of the vehicle wherein the arrow can indicate the direction of travel with a map background and without a map background; and

display the selected one, wherein the processor is further configured to display the arrow indicating the direction of travel of the vehicle under normal conditions and outputting for display the map for a predetermined period of time in response to an input operation.

6. The vehicle-mounted navigation device according to claim 5, wherein the processor is further configured to output to the display the arrow indicating the direction of travel of the vehicle under normal conditions and output for display the map when the vehicle is traveling on the guided route.

7. The vehicle-mounted navigation device according to claim 5, wherein the processor is further configured to output for display the arrow indicating the direction of travel of the vehicle under normal conditions and outputting for display the map when setting the destination.

8. The vehicle-mounted navigation device according to claim 5, wherein the processor is further configured to output for display the arrow indicating the direction of travel of the vehicle under normal conditions and outputting for display the map when the vehicle is positioned near the destination.
