Abstract
Navigation devices for vehicles, methods for producing data for searches, and methods for searching for guided routes are disclosed. Generally, a name of a first street is received, a search for second streets which are connected to an end point of the first street directly or via road links is performed, the second streets are displayed, a selection is received of one of the displayed second streets, and a branch point or an area at which the first street and the selected second street are connected with each other is stored as data for a search relating to the first street.
Claims17
A method for producing data for a search on a navigation device for a vehicle based on map data wherein a road is represented as a set of nodes and road links, the method comprising:
- receiving a name of a first street;
- searching for and displaying a plurality of second streets which are connected directly, or via a road link, to an end point of the first street;
- receiving a selection of one of the displayed second streets;
- and
- storing a branch point or an area at which the first street and the selected second street are connected with each other as data for a search relating to the first street.
A method for producing data for a search on a navigation device for a vehicle for a route search based on map data, wherein a road is represented as a set of nodes and road links, the method comprising:
- receiving a name of a first street;
- searching for and displaying at least one second street which is not connected to the first street, but is adjacent to the first street;
- receiving a selection of one of the displayed second streets;
- and
- storing an area at which the first street and the selected second street are adjacent to each other as data for search relating to the first street.
A method for searching for a guided route on a navigation device for a vehicle based on map data, wherein a road is represented as a set of nodes and road links, the method comprising:
- receiving a name of a first street;
- searching for and displaying a plurality of second streets which are connected directly or via a road link to an end point of the first street;
- receiving a selection of one of the displayed second streets;
- and
- displaying a map of a branch point or an area at which the first street and the selected second street are connected with each other.
A method for searching for a guided route on a navigation device for a vehicle based on map data, wherein a road is represented as a set of nodes and road links, the method comprising:
- receiving a name of a first street;
- searching for and displaying a plurality of second streets which are not connected to the first street, but are adjacent to the first street;
- receiving a selection of one of the displayed second streets;
- and
- displaying a map of an area at which the first street and the selected second street are adjacent to each other.
A navigation device for a vehicle for displaying a guiding route and guiding a driver to a destination, the navigation device comprising:
- storage means for storing map data representing a road, wherein the road is represented as a set of nodes and road links;
- input means for receiving a name of a first street;
- search data storage means for storing data for a search relating to the first street;
- display means for displaying guide information;
- and
- control means that is connected to the input means, storage means for storing map data, search data storage means, and display means,
- wherein in response to receiving the name of the first street, the control means searches the search data storage means for a second street which is connected directly or via a road link to an end point of the first street, and displays a map of a branch point or an area at which the first street and the searched second street are connected with each other.
A navigation device for a vehicle for displaying a guided route and guiding a driver to a destination, the navigation device comprising:
- storage means for storing map data representing a road, wherein the road is represented as a set of nodes and road links;
- input means for receiving a name of a first street;
- search data storage means for storing data for a search relating to the first street;
- display means for displaying guide information;
- and
- control means that is connected to the input means, storage means for the map data, search data storage means, and display means,
- wherein in response to receiving the name of the first street, the control means searches the search data storage means for at least one second street which is not connected, but is adjacent to the first street, and displays a map of an area at which the first street and the searched second street are adjacent to each other.
