摘要： 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.

摘要： A navigation system including a present-position sensing system for sensing a present position; information storage medium for storing map information; an input device for entering into the system the destination, a roundabout point, a bypass, and the location desired to be traversed for entry of input indicating the execution of a route search from the present position sensed by the present-position sensing system to the destination; an output device for outputting information route guidance; and a central processing unit including a route searching capability for searching for a route to the destination; a route storage capability for provisionally storing the identified route; and route guidance control for sending a signal for performing route guidance to the output device. When the roundabout point or bypass is entered in the system, a search cost for roads and intersections near to the roundabout point or bypass is raised so that route search processing can be performed. When the location desired to be traversed is set, roads near to the location desired to be traversed are retrieved for search purposes. In travel guidance, a present-position mark is displayed in either a continuous mode or a blinking mode depending on the state of travel.

摘要： A navigation system includes input means (1a) for entering a telephone number; an information storage device (3) for storing telephone-number data (3a), in which a location name inclusive of a set of coordinate is stored for each telephone number, address data (3b) in which an address is stored for each set of coordinates, and map data (3c); a central processor (4) having telephone-number retrieval means (4a) for retrieving, from the information storage device, location coordinates and location name of a telephone number entered by the input means, and address-data retrieval means (4b) for retrieving address data corresponding to the location coordinates of the telephone number entered by the input means; and display means (1b) for displaying a location name and address, which have been retrieved by the central processor, as well as a map centered on the location. Designation and entry of a location are performed by displaying the location name and address retrieved by entry of a telephone number, as well as the map centered on said location, on the display means. Since the amount of data is broken up into the telephone-number data and address data, the amount of telephone-number data can be reduced.

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.
