    摘要： According to the invention, when a target name is inputted using characters such as alphabet and numerics, strings of characters or numerics are compared with data of registered places each time one character is inputted, names of registered places including the inputted string of characters or numerics is listed, and the number of registered target names remaining on the list is displayed. When the target name is inputted in characters, the inputted data is compared with a list of the registered names having word components arranged in different orders with respect to a single official name by a forward match comparison, and the number of registered target names remaining on the list with forward match is displayed. When the number of the inputted characters or numerics increases and the number of registered target names remaining on the list decreases, a list of the registered place names is displayed. The target name is selected from this list. When the number registered target names remaining on the list is one, the target name is selected. A map of the vicinity of the target name thus selected is displayed.

    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： 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.

    摘要： In traveling toward a destination, locus data for routes traveled by a vehicle is repeatedly learned and stored, and a route is identified in route searching using the stored locus data. The stored locus data may be rearranged or deleted, and undesired locus data is not used in route searching. Storage of locus data may be limited to certain areas so as not to store undesired locus data. The geographical coordinates of the stored locus data are corrected, as required, and locus data such as links are correctly shown on a map.

    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： A navigation apparatus reduces route search time while providing guidance in conformity with drivers' preferences, by selectively conducting either a full-range route search or a more limited, local area search, in accordance with detected conditions and responsive to occurrence of an off-route event. For example, the full-range route search is conducted pursuant to a determination that the vehicle has gone straight at a predetermined number of certain intersections where current guidance has directed a turn.
