The navigation device 400 is classified into an in dash type and an on dash type according to an installation type in the vehicle 200. The desiccation type navigation device (vehicle navigation) is inserted into a predetermined space allocated in a dash board of the vehicle 200 and fixedly mounted. The navigation device (vehicle navigation device) of the on-demand type is mounted on a dashboard of the vehicle 200 or installed using a constant support near it, and thus can be detached and carried from the vehicle 200.

The navigation (vehicle navigation) device 400 according to the present embodiments includes such an instant type and on-demand type navigation (vehicle navigation) device, and in addition, from a GPS (Global Positioning System) satellite in the vehicle 200. It includes all of the information processing apparatus capable of receiving and / or processing traffic information, such as various portable terminals that can perform a navigation function in conjunction with the GPS receiver for receiving the transmitted navigation message.

As shown in FIG. 6, the navigation device 400 receives a global positioning system (GPS) signal received from a satellite, and based on the received GPS signal, the navigation device (telematic terminal 200 or mobile communication). A GPS module 401 for generating first vehicle position data of the same position as that of the terminal 100; A dead-reckoning (DR) sensor 402 for generating second vehicle position data based on a driving direction of the vehicle and the speed of the vehicle; A storage unit (or memory) 404 for storing map data (including map data predetermined according to a scale ratio) and various information; A vehicle estimated position is generated based on the first vehicle position data and the second vehicle position data, and the generated vehicle estimated position and a link in the map data stored in the storage unit 404 (map matching link or map matching road). A map matching unit 403 for matching and outputting the matched map information (map matching result); A communication unit 408 for receiving real-time traffic information from the information providing center and / or surrounding vehicles through the wireless communication network 500 and performing telephone communication; A controller 407 for generating road guidance information based on the matched map information (map matching result); A display unit 405 for displaying road guidance maps (including interest point information) included in the road guidance information and the traffic information; And a voice output unit 406 which outputs road guide voice information (road guide voice message) included in the road guide information and a voice signal corresponding to the traffic information.

The controller 407 automatically changes the scale of the map data based on the distance from the current location to the guide point. For example, the controller 407 detects the distance from the current position to the guide point, and if the distance from the current position to the guide point is long so that the detected distance can be displayed on the display unit 405. The map data is automatically reduced so that the user can recognize the guide point (when the detected distance cannot all be displayed on the display unit 405), and if the distance from the current location to the guide point is short. The map data is automatically enlarged to display the guide point in detail (close to the guide point). Here, the guide point refers to the turn point closest to the current position among a plurality of turn points existing from the current to the destination.

When the controller 407 cannot display all of the distances (paths) from the current location to the guide point due to the scale of the currently displayed map data, the controller 407 moves from the scale of the currently displayed map data to the guide point. The map data included in the scale of the map data indicating the distance (path) of the data is retrieved from the storage unit 404, and the retrieved map data is automatically and sequentially displayed on the display unit 405. For example, the control unit 407 is a scale (e.g., scale) of map data indicating a distance (path) from the scale of the currently displayed map data (e.g., 200 meters scale) to the guide point from the current position. Map data included in the 400-meter scale (for example, 200-meter scale, 250-meter scale, 300-meter scale, 350-meter scale, 400-meter scale map data) is automatically and sequentially displayed on the display unit 405. .

For example, the map matching unit 403 generates a vehicle estimation position based on the first position data and the second position data, and generates the estimated vehicle position and the map data stored in the storage unit 404. The links within the link are matched according to the link order, and the matched map information (map matching result) is output to the controller 407. The map matching unit 403 may output road attribute information, such as a tomographic road or a double layer road, included in the matched map information (map matching result) to the controller 407. In addition, the function of the map matching unit 403 may be implemented in the controller 407.

The storage unit 404 stores map data. At this time, the stored map data includes geographic coordinates (Geographic Coordinate or longitude coordinates) for displaying latitude and longitude in degrees and seconds (DMS unit: Degree / Minute / Second).

Judge.

When the path (distance) from the current location to the guide point cannot all be displayed on the display unit 405 (for example, the path from the current location to the guide point at the current map scale). When it is impossible to display all of the above), the map data is automatically reduced so that the user can recognize the guide point. For example, the control unit 407 may be a scale (eg, 0.5 mile scale map) of map data indicating a route from the current position to the guidance point from the scale of the currently displayed map data (eg, 150 ft scale map data). The preset map data (for example, 200ft, 250ft, 300ft, 350ft, ..., 0.45mile scale map data, etc.) included in the data is retrieved (S14).
