Abstract
Upon recognizing the shapes of buildings or facilities, the buildings or facilities can be identified and destinations can be designated simply and easily. The display of a house map and a road map is changed over depending upon predetermined conditions. This makes it easy to navigate to the destination. When the destination is shown on the house map, a guide route is identified on a road adjacent to the building at the destination. This makes it easy to see where in the vicinity of the destination the car arrives.

14. A navigation device for a vehicle, comprising:
-
a storage device storing house shape data that are related to house shapes representing shapes of places that are included in a predetermined region and are sectionalized on a plane, positions of the places, and data related to the places; a display for displaying a picture; means for generating house map data to display a house map by using the house shapes of the places that are included in the predetermined region and are sectionalized on the plane, the display displaying the house map as the picture based upon the house map data that are generated; means for generating road map data to display a road map by using a road network and geographical data included in the predetermined region, the display displaying the road map as the picture based upon the road map data that are generated; means for designating a point that becomes a destination; means for searching coordinates of the point that is designated; means for searching the house shape data in which the coordinates of the identified point are included in a range of the house shape data; means for generating for display as the picture data related to the place identified as the searched house shape data for the destination, the storage device also storing place data related to places that may be selected as drop-in places; means for searching from the place data places that correspond to a selected genre and that meet conditions that are input as drop-in places, displaying on the display the house shape of the identified place on the house map in a form distinguishable from house shapes of other places; means for designating a drop-in place out of recommended drop-in places that are displayed, then displaying the house shape of the designated drop-in place in a form distinguishable from the other recommended drop-in places; means for searching coordinates of the point designated as the drop-in place; means for identifying the house shape data in which the coordinates of the point of the designated drop-in place is included in the range of the house shape data for the drop-in place; means for setting a guide route to the destination and a guide route to the designated drop-in place; means for detecting a present position of a moving means, the display displaying the guide route together with the detected present position; means for determining whether the present position is within a predetermined distance from the destination when the guide route is being displayed; means for determining whether the house map or the road map should be displayed depending upon predetermined conditions, the house map displayed around the destination when the destination is set and the present position of the moving means is determined to be within a predetermined distance of the destination; means for determining whether a range of the house map for display lies outside a coordinate range of data of the house map that can be displayed; means for changing over the display of the house map to the road map when the range of the house map for display lies outside the coordinate range of data of the house map that can be displayed; means for storing in the storage device reduced scale data of the road map when the road map displayed is changed over to the house map; means for returning the display to the road map again on the reduced scale in effect when a road map display was previously changed over to the house map; means for determining whether the house map or the road map be displayed depending upon a manual operation by a user; means for determining whether the vehicle is moving; and means for inhibiting the display of the house map when it is determined that the vehicle is moving.

15. A navigation device for a vehicle, comprising:
-
means for calculating a route to a destination that is input; means for providing guidance to a user according to the calculated route; a storage device for storing data related to the calculated route, the storage device storing building data for indicating the shapes of integrated units; means for inputting a point to include the destination or a passing point; means for searching from the building data an integrated unit corresponding to the point that is input, wherein when the integrated unit is the destination, the means for calculating calculates the route to a point on a road adjacent to the identified integrated unit as an end point of the route. - View Dependent Claims (16, 17, 18)
