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.

Abstract: A vehicle navigation system includes a simulated run mode along with a normal navigation mode. In the simulated run mode, a simulated present position is calculated to move in accordance with simulated motion so that route guidance information is presented to the viewer in the same manner as during actual navigation. The simulated motion may be increased or decreased, may be stepped or continuous, and/or may be controlled in accordance with stored speed information on the roads of the route.

Abstract: An apparatus to facilitate volume control for route aural guidance. When supplying a guidance voice to a loudspeaker 34a, a voice control section 30 disconnects the loudspeaker 34a from audio and outputs the guidance voice through the loudspeaker. A volume control screen is displayed on a display section 28 where the user adjusts the volume by touching the screen. When the voice control section 30 switches a signal to the loudspeaker 34a, a mute circuit 40a is operated to mute the voice output before the voice is output through the loudspeaker 34a. When the user terminates volume adjustment, the voice control section 30 outputs a voice for volume confirmation or check at the adjusted volume through the loudspeaker 34a. The user can check the adjusted volume at this time.

Abstract: In a navigation apparatus for setting a route from a designated departure point to a destination and providing guidance along the route, there are provided, as map data used in route exploration, node data [FIG. 15(b)] comprising position information and information relating to the attributes thereof, intersection data [FIGS. 2-5(b), FIG. 15(b)] comprising information relating to intersections, and road data [FIGS. 2-5(a), FIG. 15(c)] comprising information related to roads. Information such as roads between intersections and intersections which are the starting and end points of roads are obtained from the intersection data and road data, and an optimum route is retrieved by comparing routes. The map data is put into the form of a layered structure, as shown in FIG. 1, a branch road network is developed in an upper-layer (2) connected to a trunk road network with respect to a higher-order layer (1) of the trunk road network, block division is performed, and exploration from a lower-order layer to intersections connected to a road network of the higher-order layer is successively repeated. The foregoing makes it possible to perform processing upon limiting the range of exploration, and to raise the speed of exploration processing. In addition, the work area needed for exploration can be reduced and storage data can be conserved.

Abstract: Even when the present position does not exist on a guide road after deviation from an established guide route, a guide road is identified and a more advantageous route is identified. Furthermore, only a minimum amount of required data are displayed on the map picture. The searching again is executed by taking the direction of progress of the car into consideration. Street names of the roads are displayed on the guide map, enabling a guide route to be easily recognized. A particular area is specified by a postal code number or by a telephone number, and the streets or the facilities in the specified area are displayed. This makes it easier to search the destination.

Abstract: An external storage device having navigation data and programs stored therein to perform a route search and provide route guidance, and a central processing unit which includes a program storage flash memory and program loading means for loading programs from the external storage device into the flash memory. The programs stored in the flash memory are run to perform a route search and provide route guidance. The central processing unit compares a version of each program stored in flash memory with a version of the program stored in external storage device, so that when the version of the program stored in the external storage device is more current than that stored in the flash memory, the program is loaded from the external storage device into the flash memory.

Abstract: In a navigation apparatus for a vehicle, after the present position of a vehicle is obtained, a position on a map which corresponds to the present position of the vehicle is obtained. Subsequently, the heading direction of the vehicle is detected. When the vehicle is traveling on the left-hand lane, coordinate conversion is performed such that a present position mark is shifted leftward from the center of the road by 1/4 of the road width. This makes it possible to display a route while preventing the route from overlapping with the centerline of the road. In another navigation apparatus for a vehicle, a structure-profiled map on which a structure-representing shape and a road are drawn is displayed so as to provide road guidance, wherein a route is displayed on the structure-profiled map along a road which is displayed for guidance. The display of the route is performed such that the route is shifted from the center line of a road toward a lane on which the vehicle is traveling. The route is displayed by using a pattern having a width corresponding to the width of the road in accordance with the lane of the road to be guided.

Abstract: Road or other guidance is provided by displaying a structure-shape map showing building shapes and roads. Drawing of building shapes on the map is restricted according to a specific condition, e.g. the travel condition of the vehicle, or the screen scroll mode, by setting the display color for building shapes to the same color as that for a background, or by not drawing any of them, thereby preventing the screen from becoming difficult to see even during scrolling. For the structure-shape map, a storage device (3) stores map data having a name and a coordinate string for each shape of various structures and information belonging to each structure. A guidance controller (4) decides colors, color densities, patterns thereof, etc. for shapes as display modes on the basis of information belonging to the structures, e.g. the classification and height of each structure, and other detailed information (e.g. scale of construction), retrieves information belonging to a structure concerned, together with information regarding surroundings, and displays, on a display (12), shapes and names according to the decided display modes, thereby giving guidance. The structure-shape map may be displayed centered on a structure having a telephone number retrieved by entry of the telephone number.
