Abstract

An in-vehicle navigation device in which a route search block outputs a search result of a guiding route from an exit of the expressway to an entrance of the expressway by way of the selected facility to a display block to make the display block display the search result in a case where a present position detected by a present position detection block is on an expressway and where position of a target facility selected by a facility information selection block is outside the expressway.

Claims

1. An in-vehicle navigation device comprising:

a facility information designation part for designating information of a facility to be searched;

a threshold value setting part for setting a threshold value of a search criterion of the facility;

a present position detection block for detecting a present position of a vehicle;

a facility information selection block for selecting the facility satisfying the threshold value set by the threshold value setting part among information of the facility designated by the facility information designation part; and

a route search block that in a case where the present position detected by the present position detection block is on an expressway and where a position of the facility selected by the facility information selection block is outside the expressway, outputs a search result of a guiding route from an exit of the expressway to an entrance of the expressway by way of the selected facility to a specified display block to make the specified display block display the search result.

2. The in-vehicle navigation device as claimed in claim 1, wherein the route search block makes the display block display a total running distance from the exit of the expressway to the entrance of the expressway by way of the selected facility as a search result.

3. The in-vehicle navigation device as claimed in claim 2, wherein the route search block makes the display block display a running distance from the exit of the expressway to the selected facility and a running distance from the selected facility to the entrance of the expressway as a search result in addition to the total running distance.

4. The in-vehicle navigation device as claimed in claim 1, wherein the route search block makes the display block display a total predicted running time from the exit of the expressway to the entrance of the expressway by way of the selected facility as a search result.

5. The in-vehicle navigation device as claimed in claim 4, wherein the route search block makes the display block display a predicted running time from the exit of the expressway to the selected facility and a predicted running time from the selected facility to the entrance of the expressway as a search result in addition to the total predicted running time.

6. The in-vehicle navigation device as claimed in claim 1, wherein the route search block makes the display block display a search result of all facilities selected by the facility information selection block as a list.

7. The in-vehicle navigation device as claimed in claim 6, wherein the route search block makes the display block display running distances from the exit of the expressway to the respective facilities and running distances from the respective facilities to the entrance of the expressway as a list in addition to the search result of all facilities selected by the facility information selection block.

8. The in-vehicle navigation device as claimed in claim 6, wherein the route search block makes the display block display predicted running times from the exit of the expressway to the respective facilities and predicted running times from the respective facilities to the entrance of the expressway as a list as a list in addition to the search result of all facilities selected by the facility information selection block.

9. The in-vehicle navigation device as claimed in claim 1 further comprising a display content setting part for setting a portion of search content of the search result displayed as a list by the display block according to an operation, wherein the route search block displays the portion of search content set by the display content setting part as a highlighted image on a screen of the search result displayed as a list.

10. The in-vehicle navigation device as claimed in claim 1, wherein the route search block changes a threshold value set by the threshold value setting part to perform a search for a guiding route according to an area where the facility selected by the facility information selection block is located.

11. The in-vehicle navigation device as claimed in claim 10, wherein in a case where a density of map information of the area where the facility is located is higher than a basic density, the route search block changes the threshold value to a smaller value and in a case where the density of map information of the area where the facility is located is lower than the basic density, changes the threshold value to a larger value.

12. The in-vehicle navigation device as claimed in claim 1, wherein the route search block changes the threshold value set by the threshold setting part to perform a search for a guiding route according to a specific facility selected by the facility information selection block.

13. The in-vehicle navigation device as claimed in claim 1 further comprising a vehicle information acquisition part for acquiring information of the vehicle, wherein the route search block changes the threshold value set by the threshold value setting part to perform a search for a guiding route on a basis of information of the remaining amount of fuel acquired by the vehicle information acquisition part.

14. The in-vehicle navigation device as claimed in claim 1 further comprising a display content setting part for changing an order of display of a plurality of facilities displayed as a list by the display block.

15. The in-vehicle navigation device as claimed in claim 14, wherein the display content setting part changes the order of display of a plurality of types of facilities for each type according to a setting operation.

16. The in-vehicle navigation device as claimed in claim 14, wherein the display content setting part changes the order of display of a plurality of facilities of the same type for each brand name of the facilities.

17. The in-vehicle navigation device as claimed in claim 1, wherein in a case where the facility selected by the facility information selection block can not be reached within business hours of the facility, the route search block changes the facility to other facility to perform a search for a guiding route.

18. The in-vehicle navigation device as claimed in claim 1 further comprising an extra-vehicle information acquisition part for acquiring information other than that on the vehicle, wherein the route search block changes the threshold value of a total predicted running time set by the threshold value setting part to perform a search for a guiding route on a basis of road traffic information acquired by the extra-vehicle information acquisition part.
