Navigation system and method for supporting destination input in a navigation system
First Claim
1. A navigation system for a motor vehicle, comprising:
- a navigation module for route planning;
a display arrangement configured to display information including textual indications of location, additional items of information concerning the locations indicated by the textual indications of location, the additional items of information corresponding to respective destinations within the locations, each destination being assigned respective geographic coordinates, and the display arrangement being further configured to display route information;
an input arrangement configured to receive a hierarchical, interactive destination input by, in conjunction with the display arrangement and conditional upon a selecting of an ambiguous textual indication of location by a user, which ambiguous textual indication identifies a plurality of destination alternatives, each of which is displayed with the same name;
initially displaying the plurality of destination alternatives identified by the ambiguous textual indication as a list, without displaying the additional items of information,providing the user with a choice between a plurality of categories of additional information,receiving the choice from the user, andsubsequently displaying, in response to a user selection of a particular one of the plurality of destination alternatives, those additional items of information that correspond to the selected destination alternative and which belong to a category specified by the choice; and
a memory in which each destination alternative is stored together with corresponding geographic coordinates, and the geographic coordinates of the selected destination alternative are used to determine the additional items of information that correspond to the selected destination alternative.

Abstract
A possibility for simplifying the inputting of the destination in a motor vehicle navigation system by providing the user with useful additional items of information for the specification of ambiguous destination indications. Such a navigation system includes means for destination input, a navigation module for route planning, and means for displaying information, in particular indications of location, additional items of information concerning the indications of location, and route information, the means for destination input supporting a hierarchical, interactive inputting of the destination, by providing the user, in the case of ambiguous textual destination indications, with a choice of destination alternatives, including additional items of specifying information, until an unambiguous destination indication is made. The textual destination indications are stored together with corresponding geographic coordinates. The geographic coordinates are used for the determination of the additional items of information for the specification of destination alternatives.

4. A method for supporting an inputting of a destination in a navigation system for a motor vehicle, the navigation system including an arrangement for destination input, a navigation module for route planning, and an arrangement for displaying information including textual indications of location, additional items of information concerning the locations indicated by the textual indications of location, the additional items of information corresponding to respective destinations within the locations, each destination being assigned respective geographic coordinates, and for displaying route information, the method comprising:
-
performing, by an evaluation unit, the destination input in a hierarchical and interactive fashion by, conditional upon a selecting of an ambiguous textual indication of location by a user, which ambiguous textual indication identifies a plurality of destination alternatives, each of which is displayed with the same name; initially displaying the plurality of destination alternatives identified by the ambiguous textual indication as a list, without displaying the additional items of information, providing the user with a choice between a plurality of categories of additional information, receiving the choice from the user, and subsequently displaying, in response to a user selection of a particular one of the plurality of destination alternatives, those additional items of information that correspond to the selected destination alternative and which belong to a category specified by the choice, wherein in at least one query level of the destination inputting, the displaying the additional items of information that correspond to the selected destination alternative includes displaying additional items of textual information including geographic information, determined on the basis of geographic coordinates of the selected destination alternative. - View Dependent Claims (5, 6)
