摘要： A navigation system provides road guidance by displaying information relating to roads on a structure shape map, together with landmark information, in such a manner that only information around the present position is highlighted. The system retrieves road information in the direction of travel from the present position according to the vehicle speed, or road information within a predetermined angular or distance range in the direction of travel. Information relating to roads includes information indicating a one-way road, information indicating a road into which entry is prohibited, and information indicating a pedestrian crossing and a railroad crossing. These items of information are displayed by using marks, and the landmark information is displayed by using landmarks, thereby displaying information necessary for travel in a readily perceivable manner according to the travel conditions. When the vehicle enters a parking lot in the middle of the guidance for a route to a destination, the system searches for a route from the parking lot to the destination and outputs the found route by using a structure-shape map. The parking lot in this case is one within a predetermined walking distance from the destination. If the parking lot is in close proximity of the destination, further guidance is not necessary and the guidance is terminated.

摘要： A vehicular navigation system includes: a current position detection unit for detecting the current position of the vehicle; an information storage unit for storing map information for conducting route searching and for providing route guidance; an input unit for inputting a destination and inputting instructions for executing a search of the map information for a route from the current position detected by the current position detection unit to the destination; an output unit for outputting information for route guidance; and a central processing unit for temporarily memorizing a route detected by the route search and for outputting a signal to the output unit to provide route guidance according to the memorized route. The central processing unit judges whether or not one information storage unit has been replaced by another and, when replaced, if the destination has not been reached, conducts another route search from the current position to the destination.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： In a navigation system, user preferred road data is determined and stored during travel to supplement fixed road data such as map data, intersection data, node data, and destination data stored in CD-ROM for subsequent use in providing route guidance in accordance with user road preferences. The user preferred road data is the data of actual trips, and the preference of the user is reflected in the user preferred road data. To determine user preferences, either the user preferred road data is compared to the fixed road data or a searched route calculated from the user preferred road data and CD-ROM data is compared with the searched route calculated from CD-ROM data. By using the determined user preferences in route searching, it is possible to provide more elaborate route searching and route guidance in accordance with the preference of the user.

摘要： A navigation system calculates a route from a present position of a vehicle to a destination and provides guidance based on the calculated route. When the vehicle is within a given distance from a next approaching branch point requiring guidance, branch points existing within a given distance from next approaching branch point are determined and direction information for the branch points is acquired. The acquired direction information is compared with direction information at the next approaching branch point, and a common direction information is displayed based on the result of the comparison. Also, the navigation system according to the present invention detects a name of an interchange where the vehicle is to exit from the course and a distance to said interchange based on the present position of the vehicle in case the road where the vehicle is currently driven along is an expressway or a toll road. The navigation system according to the present invention calculates a route from the present position to the destination and properly calculates and provides guidance for the expected time of arrival at the destination as the vehicle moves.

摘要： In a navigation apparatus for a vehicle, an entire route from a start point to a destination is determined and the vehicle is guided to the destination in accordance with the determined route. In the navigation apparatus, an entire route from a start point to a destination is first determined. Route determination is performed for a part of the entire route in accordance with a request of a user, and the entire route to the destination is determined again based on the result of the determination performed for the part of the entire route. The navigation apparatus has a first remaining-distance displaying unit and a second remaining-distance displaying unit. The first remaining distance display unit displays an arrow indicating the route and the remaining distance to an intersection. The second remaining-distance display unit deletes the display of the distance provided by the first remaining-distance display unit and changes the length of the arrow, which indicates the route, as the vehicle advances.
