摘要： In a satellite navigation system, map data stored in a server is partially updateable. The map data is produced to be divided into a plurality of sets of map data mutually-independent set by set, and stored in the server. The map data is updated every set of the divided map data, according to necessities. Such update operations are addition of a new set of map data, deletion of a certain set of map data, and replacement of a certain set of map data with a new set of map data. The map data is formed into a layered structure composed of data of layers, blocks, and objects. For reloading the map data, it is sufficient that only one or more sets of map data that has been updated are delivered from the server to each terminal. Hence an amount of map data to be downloaded can be reduced.

摘要： A navigation device is provided with detailed map information of service areas and parking areas on freeways, and in the event that the vehicle to which the navigation device is mounted enters a service area for example while driving along the freeway which is a guided route, the navigation device reads out detailed map information of the service area which the vehicle has entered and displays a detailed map of this area such that the driver can readily understand the location of parking space, restaurants, stores, etc., and also displays the current position of the vehicle. Thus, in the event that the vehicle enters a service area or parking area while on a guided route, where what is within the area and where the vehicle is can be displayed in a readily understood manner, by the vehicle entering the area.

摘要： The present invention is directed to a navigation apparatus capable of performing a proper voice guidance even in such a case that signals transmitted from GPS satellites cannot be received, but a current location cannot be judged. The navigation apparatus of the present invention is featured by such a navigation apparatus in which signals transmitted from GPS satellites are received so as to measure a current location, the measured current location is displayed on a screen in connection with a map, a guidance route up to a destination place is set, and a guidance is notified every predetermined guidance point. In this navigation apparatus, when the signals transmitted from the GPS satellites cannot be received, if a current location is located on the guidance route, then a virtual current location is displayed in such a manner that the virtual current location is moved on the guidance route at a predetermined speed, and a guidance is notified every predetermined guidance point.

摘要： A link that is closest to a departure place of one's vehicle is detected by a route searching. When a U-turn route link to come back from the closest link by passing from the closest link through the U-turn route again to the closest link is detected, a U-turn guide is made, based on a signal of this detection, to the effect that a return is made to the present position after a U-turn.

摘要： A server in an information base determines a route (server route) from a place of departure to a destination, transmitted from a client terminal of a navigation unit via communication, using information in a server database. On the other hand, the client terminal determines a route (client route) from the place of departure to the destination using information in a client terminal database. Either the server or the client terminal determines whether or not the server route and the client route are identical based on information concerning guiding points of each route, and the client terminal then performs route navigation of a route in a section where the routes are identical using the information in the client terminal database and a route in a non-identical section where the routes are not identical using the information in the server database. In this way, the information in the client terminal database is effectively used in the route navigation and thereby an amount of information to be transmitted to the client terminal from the server is decreased.

摘要： A method and apparatus are provided for calculating potential paths between source and destination locations. First and second map databases are provided that are indicative of roadway networks for geographic regions bounded by region edges and containing source and destination locations. The first and second map databases, are non-adjacent, non-contiguous such that the region edges of the first map database are separate and distinct from region edges of the second map database. Potential paths are calculated through the roadway network of the first map database up to a node or segment at which each potential path intersects a region edge of the first map database, thereby defining a node/edge coordinate. A transition location is obtained in the second map database that geographically corresponds to the node/edge coordinate at which a given potential path intersected the region edge of the first map database. The calculation continues from the transition location through the roadway network of the second map database. The method and apparatus may include organizing the map databases into a map hierarchy to define tiers for the map databases. The calculation process searches potential paths utilizing the tier-one map databases until each potential path intersects a map edge of the tier-one map, databases. Thereafter, the search through potential paths continues automatically based on the lower tier map databases.

摘要： The method calculates by means of a navigation device an optimized route to a final destination, which is constrained to pass through at least one transition region of a real road network. Each transition region corresponds to a surface region of a stored digital map, which represents the road network with segments having resistances and nodes. The location and extent of each surface region are defined by a user of the navigation device. Relevant segments are stored in a via area list (VAL) in the navigation device. Route segments are optimized in the navigation device by a route-searching algorithm and are stored in route tables. Segment optimizations are executed and results are stored in separate sectional route tables. The overall resistance of the route is minimized under constraint that it passes through the at least one surface region. A navigation apparatus for performing this method is also described.

摘要： The invention provides a method for creating a real-time recording of a mobile vehicle route using a wireless communication system. The recording is initiated by the driver of the vehicle. Positional information is obtained for the vehicle at set time intervals using a global positioning system. The positional information is recorded by an on-board system and saved along with a nametag assigned by the driver. The vehicle initiates a call to a predetermined number and uploads the recording to a central storage location. The recorded route is displayed on a Web site and can be viewed and modified by an identified user.

摘要： In a navigation apparatus, a CPU searches for a plurality of routes from a starting point to a destination. These routes share the same starting point and the destination, but vary in their course along the way. Then for route selection, the CPU refers to position information provided by a locator to determine on which of the routes the user is now moving. In this manner, the navigation apparatus can automatically select one route from several derived through the route search.
