Abstract

In a method for operating an infotainment system of a motor vehicle for searching in a database in which at least one database entry with a distinct object identifier and corresponding metadata is stored a search term is entered into an input field of an input unit. During entering of the search term an input completion unit searches through a search history for a search term that matches the partial input already present in the input field. The input unit then completes the partial input in the search field on the basis of the search term found in order to provide an input suggestion. When the search term is entered, additionally a searching unit searches in the database for at least one database entry which has an object identifier or metadata that at least partially matches the partial input and/or updated content in the input field and this database entry is displayed to the user in a selection list that is different from the input field for selection.

Claims

1. A method, implemented at least by a computing device, for operating an infotainment system integrated within a motor vehicle, comprising:

entering, by a user, a search term in an input field of an input device;

selecting, by an input completion unit and during the entering of the search term, a matching search term from a search history, wherein the matching search term matching a partial input of the entered search term;

completing, by the input completion unit, the partial input in the input field based on the selected matching search term, thereby generating an input suggestion;

selecting, by a search unit during the entering of the search term and based on the input suggestion, at least one database entry with a distinct object identifier from a database, wherein

the database comprises a navigation database storing database entries such that each entry includes a name of a location as object identifier and metadata that describe the location, a media database storing data entries such that each entry includes a title as object identifier and metadata which describe a work of art having the title, and an address database storing data entries such that each entry includes a name as object identifier and metadata that describe a person or an institution identified by the name,

the object identifier or the metadata at least partially matching the input suggestion,

the input device, the input completion unit, and the search unit being each a component of the infotainment system,

the matching search term or the selected at least one database entry is selected in dependence on an actual geographical location of the motor vehicle,

the matching search term being never entered or used by the user in the search history and comprising at least one category derived from the metadata of the selected at least one database entry, and

the matching search term and the selected at least one database entry are searched in dependence on an operating mode of the infotainment system, wherein only the navigation database is searched when the operating mode is navigation mode, only the media database is searched when the operating mode is media mode, and only the address database is searched when the operating mode is telephony mode; and

displaying, by the search unit, the selected at least one database entry to the user in a selection list for selection by the user so that a discrepancy results between the input suggestion of the input field and the selected at least one data base entry displayed in the selection list, the selection list being different from the input field.

2. The method of claim 1, further comprising after the selection of the selected at least one database entry displayed in the selection list, storing the metadata associated with the selected at least one database entry in a search history of the search unit.

3. The method of claim 1, wherein in the search history, the matching search term and the at least one database entry are further selected in dependence on at least one of an actual geo-position of the motor vehicle, a predetermined target region and a predetermined prioritization.

4. The method of claim 1, wherein the matching search term and the selected at least one database entry include a part which phonetically matches the partial input.

5. The method of claim 1, further comprising generating a list from multiple matching search terms from the search history, the list containing at least one further input suggestion.

6. A motor vehicle comprising an infotainment system integrated therein, the infotainment system comprising:

a processor, implemented at least partially by hardware;

an input device, executed by the processor, having an input field for entering a search term by a user;

an input completion unit, executed by the processor, that selects a matching search term from a search history during the entering of the search term, wherein the selected matching search term matching a partial input of the search term, and the input completion unit completing the partial input in the input field based on the selected matching search term, thereby generating an input suggestion;

a search unit, executed by the processor, that selects at least one database entry with a distinct object identifier from a database during the entering of the search term and based on the input suggestion, wherein

the database including a navigation database storing database entries such that each entry includes a name of a location as object identifier and metadata that describe the location, a media database storing data entries such that each entry includes a title as object identifier and metadata which describe a work of art having the title, and an address database storing data entries such that each entry includes a name as object identifier and metadata that describe a person or an institution identified by the name,

the object identifier or the metadata at least partially matching the input suggestion,

the input completion unit or the search unit respectively selects the matching search term or the selected at least one database entry in dependence on an actual geographical location of the motor vehicle,

the matching search term being never entered or used by the user in the search history and comprising at least one category derived from the metadata of the selected at least one database entry, and

the matching search term and the selected at least one database entry are searched in dependence on an operating mode of the infotainment system, wherein only the navigation database is searched when the operating mode is navigation mode, only the media database is searched when the operating mode is media mode, and only the address database is searched when the operating mode is telephony mode; and

the search unit displaying the selected at least one database entry to the user in a selection list for selection by the user so that a discrepancy results between the input suggestion of the input field and the selected at least one data base entry displayed in the selection list, the selection list being different from the input field.
