摘要:
A vehicle navigation system is presented for performing guidance along route which produces an intersection image upon controlling a drawing area of the intersection image on the basis of information and route regarding the intersection existing on the route which requires guidance. The navigation system display control unit determines the drawing area of the intersection image on the basis of map information stored in a memory, route information stored in a route memory and information concerning an intersection requiring route information and guidance prior to producing the intersection image. In addition, the display control unit judges whether the intersection which requires route guidance is larger than the predetermined limited scale rate, and if the intersection which requires guidance is larger than the predetermined image limit, the display control unit controls a display area by reducing the scale rate so as to be able to display the entire intersection or otherwise controls the display area so as to be able to display all routes within its intersection.

An image display device is provided that includes an information storage device in which names of destinations are stored; name obtaining unit for obtaining names from the information storage device on the basis of an input device and its operation; a display for displaying character strings on a menu screen; a name display unit for displaying names obtained by the name obtaining unit in respective rows in a plurality of areas on the menu screen; and a display change unit for displaying character strings of names in a plurality of rows upon determining whether character strings of names to be displayed cannot fit in the display area. When the operator operates the input device, names are obtained from the information storage device and if character strings of names to be displayed cannot fit in the display areas, the character strings of the names are displayed in a plurality of rows.

Systems, methods, and programs for rotating font data may store font data and a plurality of conversion tables, each conversion table corresponding to a preset rotational angle. The systems, methods, and programs may select one of the conversion tables in accordance with a required angle and may rotating the font data based on the selected conversion table. The systems, methods, and programs may further store map data. The systems, methods, and programs may generate name designations of display objects included in the map data in accordance with an arrangement of the display objects on a map and may determine the required angle in accordance with the arrangement of the display objects on the map. The systems, methods, and programs may rotate characters of the generated name designations according to the required angle to create rotated name designations and may display the map data including the rotated name designations.

A voice route-guidance system for vehicles which terminates its route-guidance when the vehicle arrives at the destination and even if the present position of the vehicle is measured with low accuracy. An approach judging unit judges that the vehicle approaches a point spaced apart from a destination by a predetermined distance. A guidance termination judging unit further judges whether or not there is a point in which the route-guidance should be carried out between the present vehicle position and the destination. From these judgments, the system judges that the vehicle approaches the point spaced apart from the destination by the predetermined distance and also that all the route-guidance has been terminated. Thus, a termination unit terminates the route-guidance.

A navigation device stores road data in a storage part. The road data includes a consecutive connection of a plurality of links as a link queue, the plurality of links acquired by sectioning a road length into a plurality of pieces. The navigation device includes a guidance part that performs route search and guidance to a destination using the road data. The link queue includes a standard link for which, based on a sectioned link of a specific road stored in the storage part, information relating to the sectioned link is stored as road-related information in the storage part, and an invariance link for which the road-related information is not stored in the storage part if there is no difference in the road-related information compared to an adjacent link in the link queue. A navigation road data creating device is also provided.

The present invention provides a navigation system for guiding a driver along an optimum route by comparing a route with preference on the traveling direction of a vehicle with a route with no preference on the traveling direction thereof when the driver is guided from the current position thereof up to a destination. To search for a route, a first route with preference on the traveling direction of a vehicle is calculated (1) and then, a second route with no preference on the traveling direction thereof is calculated (2). An appropriate route is selected from found routes according to a predetermined setting condition (3) and displayed on screen. The setting condition includes comparison of distances of respective routes and time lengths required for traveling thereon, ease of traveling, width and type of roads, scenery and the like. In a case where distances of the respective routes, for example, are compared with each other, if the distance of the first route is longer than the second route by at least a predetermined value, the second route is displayed, and if the first route is not longer than the second route by at least the predetermined value, the first route is displayed.

Navigation apparatuses, methods, and programs having conducted a search for an original driving route that goes through a plurality of destinations in a designated order and provided route guidance based on the original driving route, receive an input of a new destination. Upon receipt of the new destination, the apparatuses, methods, and programs designate an ordinal position of the new destination in terms of the designated order and receive an input of a destination change request. When the destination change request is received, the apparatuses, methods, and programs automatically delete one or more of the destinations in ordinal positions within the designated order that are before the ordinal position of the new destination, conduct a new search for a new driving route based on the new destination, and output the new driving route. When an added destination request is received, the apparatuses, methods, and programs conduct a search for the new driving route including the new destination, without deleting destinations in ordinal positions within the designated order that are before the ordinal position of the new destination.

Systems, methods, and programs for navigation guide to a destination along a searched route and receive road information and traffic information including traffic congestion information. If according to the received traffic congestion information, traffic congestion is detected on the guidance route, the systems, methods, and programs search a detour route to avoid such congestion. The systems, methods, and programs guide to a destination along the detour route. If traffic congestion which was previously avoided by the detour route is determined to have been eased, the systems, methods, and programs search for a new route and switches guidance from the detour route to the new route.
