Abstract

The invention relates to a method for operating an infotainment system (10) of a motor vehicle in order to search in a database (12) in which at least one database entry (30) with a distinct object identifier (32) and corresponding metadata (38) is stored. A partial input (20) of a search term input is received by an input unit (14) from a user and an input completion unit (22) searches through a search history (24) for a matching search term (26). The input unit (14) then completes the partial input (20) on the basis of the search term (26) found to provide an input suggestion (28) and then a matching database entry (30) in the database (12) is determined (S14). The invention addresses the problem of providing in the infotainment system, for automatic input completion, a list of search terms that are useful for the input completion. To this end, after the search the metadata (38) from the determined database entry (30) is stored in the search history (24).

Description

Auto infotainment system with automatic input adjunct in the search term input

DESCRIPTION:

The invention relates to a method for operating an infotainment system of a motor vehicle to assist a user in entering a search term for a search in a database. For this purpose, an automatic input supplement is at the input of the search term would be realized by the process. The invention comprises also a motor vehicle having a correspondingly operated the method infotainment system.

When looking navigation destinations in a navigation database of a navigation system of a motor vehicle that a list of navigation targets is proposed on the basis of an already user-entered combination of letters that the user has previously been selected once during a previous search can be provided. A storage device for those already selected in a search navigation destinations is referred to as search history. The user can then directly select a list entry from the list to shorten the search term input. This term can then, if appropriate after entering more characters, a search in the navigation database will be used. The list described only contains items that are the user already known.

From DE 10 2006 057 921 A1 a possibility is known to determine a more extensive list of supplementary proposals. Then already carried out a search in a database based on the partial input already entered by the user after each entry of a character or group of characters and displayed the interest found after each entry. A posted for this search search unit can perform a free text search or full text search in the database based on a full-text index. The search can be limited to navigation destinations that are located within a predetermined radius around the current position of the navigation device. Finally, the search unit can also detect similar sounding at the free text search, but other written terms and record the set of possible targets. The disadvantage of a direct search for each input step that the search at first when the partial input already entered by the user to be very short, too much can cause many useless search results. In addition, a particularly powerful computer unit for complex search is necessary. From EP 2354984 A1 it is known in this regard that a full text search can be made expense poorer if not a single full-text index, but a plurality of index tables are used which are linked via a parent table. From document is further known that a single database record a database in addition to the eigentli- chen, can unique object names for navigation destinations and category data included that indicate, for example, that a particular navigation destination is a restaurant.

The invention has the object of providing a list of search terms with an infotainment system of a motor vehicle for an automatic entry supplementation in a keyword input, useful for entering supplement.

The object is achieved by a method according to claim 1 and a motor vehicle according to claim. 9 Advantageous developments of the invention are given by the subclaims.

The inventive method can be used for searching a database in which at least one database entry with a unique object identification and with the associated metadata is stored. Metadata is generally understood a statement in connection with the invention, which is not unique to a particular database entry, but may occur in multiple database entries. In particular, the metadata is category data indicating which category is assigned a specific database entry, so for example, whether it is a restaurant or a gas station. The process of the invention starts with the prior art approach to receive in a motor vehicle through an input unit of an infotainment system of a user with a search term input. For example, the user can thus type the search term with a keyboard or a touch screen or touch pad.

If the user has made a partial entry, so no complete input of a search, so a search term is searched by an input supplementary unit of the Infotainment system depending on the input part in a search history that matches the partial input. A Search History is in the context of the invention, a term memory, are stores where possible terms for automatic input complement overall. In a search history there are usually previously by the user in connection with previous Search the database of the search terms. A "suitable" keyword is one which has a portion that matches the partial input. In the method of the searched out appropriate search term is transmitted back to the input unit, where then the partial input by the user has already entered, on the basis completes the retrieved search term to an input proposal is thus completed. Seeking a user, for example, a Chinese restaurant called "Lo tusblume," the user may have entered as part of the input, for example, have the letters "Lotu." the search history, for example, from a previous search ago already contain the search term "Lotus flower". The so searched out from the search history search for "lotus flower" can now be used to supplement the partial input "Lotu" to the input suggestion "Lotus Flower". The user can then initiate immediately without further character input the search in a navigation database in order, for example, the address to experience the restaurant or establish the restaurant as a navigation destination, or continue the search term input to refine the search.

a matching database entry is through a search unit then in the database at least supplemented to the search term input, so for example, keyword "Lotus Flower" is searched. This usually results in at least a matching database entry. The user is then at least a matching database entry for selecting the desired database entry displayed. If it is only a single search results, so only a single matching database entry is found, it can be dispensed with the selection. therefore, in principle, at least determined in to the supplemented keyword input matching database entry by the method, either by the single uses appropriate database entry or made more matching records to choose from and then a user's selection is received. If there is now a selected search result before this current search, including search history needs to be updated. for S update uchhistorie is provided in the process in a known manner, to store the respective search term input underlying itself and / or the object name from the determined database entry, eg "Lotus". At the next keyword entry thus is thus in search history, the last keyword input or the object name determined last ready. In the case of the example "Lotus Flower" but nothing is saved, since this term was already in the Search History.

In order to achieve a more meaningful automatic input complement is provided in the inventive method to store after searching in addition, the metadata from the determined database entry in the search history. in other words also information about a previously selected database entry is stored in the search history that the user has never entered himself. In the above example, in the Search History next to the already registered term "Lotus Flower", for example, now also in the search history from the metadata the name "Chinese Restaurant" are stored. This has the particular advantage that the user in a subsequent search, when it is, for example, in another city and it is clear that the restaurant "Lotus Flower" is too far away, he in a similar search for a restaurant, now, for example just can enter the partial input "Chin" and automatic input complement before beating the Einga- receives "Chinese restaurant". This is possible in the present process, although he has never even entered the search term "Chinese restaurant" or selected. Tests have shown that the additional storage of metadata leads to previously chosen search results in a drastic reduction in input costs.

The inventive method is very flexible. One embodiment provides that the database summarizes a navigation database environmentally, is stored in which the database entries each as a place name a Na me a location, that is in particular a city name, a street name, a name of a special navigation destination (point of inter- est) , the locality descriptive data is then in each database entry as metadata stored, such as a category name (restaurant, airport, Modegesc äft), a trade name (brand) of an operator (eg McDonald's®) or for example, a style, such as what sort of food one particular restaurant offers (eg vegetarian or chinese). The method is also suitable in the context of a media database for example, MP3 files or video files. This embodiment of the method provides then, that such media database includes database entries (ie song or movie title), and as metadata in each case comprises as an object name a title information describing the titled by the title art. Such metadata can thus specify, for example, a music genre or genre or artist or director.

The process can verwen- also associated with a database are det, which includes an address database in which the database records as an object name one name (ie, a name of a person or an institution) and metadata then information that each person named are described or institution stored.

A particular preferred embodiment of the method provides that, in the search history matching search term in dependence on a current geolocation of the motor vehicle and / or is retrieved from a predetermined target region and / or a predetermined prioritization. The basis of the current geo-position, as for example by a GPS receiver (GPS - Global Positioning System) can be determined, has the advantage that the user even when entering the metadata commonly held, as a rule, such as the restaurant category "Chinese restaurant "or the name of a Kettenbetrei- bers (McDonald's®), still receives a variety of results to its current location. the same applies to the basis of a given target region, so for example, a navigation destination. with a prioritization means that the user, for example, initially as an input proposal city ​​names given and displayed by big cities only when rejecting the proposal as a further input input proposal a city name of a smaller town is proposed from the search history. such prioritization can achieve that already USAGE the first or second input proposal for the user is dbar.

Another preferred embodiment of the method provides that in the search history matching the search term in response to an operation mode of the infotainment system, so dependent on context is searched. For example, whenever the user makes just one input to a navigation, only those search terms are included in the search history that have to do with navigation destinations. In contrast, if a search term input for example, a telephone call made, the search in the Search History also addresses and related metadata can be restricted. Important to differ here is that does not occur in the prior art search in a search history context sensitive, but only searching the database itself.

A further advantage results when a keyword is selected manufacturer in the search history, which has a portion that matches only part of the phonetically typing. so the user does not have to write exactly as it is stored in the search history to receive an input proposal the term. This is particularly in the process beneficial as are taken from the metadata search terms in the search history that the user has previously never wrote.

According to the invention may be formed as the input proposal, either a single keyword or a list of a plurality of matching search terms.

As stated above, one of the invention, a motor vehicle with an infotainment system. In the inventive automotive infotainment system is adapted to perform an embodiment of the method according to the invention.

The invention is once again explained in more detail using a concrete embodiment. For this purpose, the single figure shows a block diagram for an infotainment system, which carries out an embodiment of the inventive method. In the figure (Fig.) An infotainment system 10 and a database 12 are shown. The infotainment system 10 may be installed in a motor vehicle such as a passenger car. Through the infotainment system 10 functions can be provided as navigation assistance and internet access. The database 12 may also be part of the motor vehicle. You can also completely or partially by a vehicle-external device, such as a server on the Internet, be provided. The database 12 can be, for example, from a navigation database, an address database or a media database, or a combination.

For further explanation, assume that a (not shown) user wants to specify a navigation destination in the infotainment system in the car. To this end, the user activates a navigation mode of the infotainment system 10. An input unit 14 Infotainment system 10 enables the user then to set a keyword input that is used for a search data to the navigation destination in the database 12th The input unit 14 may include an input device 16, such as a touchpad, buttons on a touch screen or a rotary-push control in a known manner.

Furthermore, an input field can by input unit 14 may be provided 18, shows where the user reasonable the characters already entered gets. The input unit 14 may be provided both by hardware components as well as by program modules of the infotainment system.

By means of the operating device 16 has already entered the user in the example, a partial input 20, such as the beginning of a place name to which he would like to drive. In the figure, the letters "AB" as the partial input 20 is symbolically indicated. To the infotainment system 10 also has an input supplementary unit is part 22. This may be a program module or a hardware component of the infotainment system 10 act also. The input supplementary unit 22 facilitates the user to input the place name. on the basis of the input part 20 is determined by the input supplementing unit 22, which place names, the user likely wants einge- ben. This place name is then input to the user as a suggestion.

To this end, in a step S10, the input portion 20 is transmitted from an input unit 14 to the input supplementing unit 22nd By entering supplementary unit 22, a possible Keywords are searched in a search history 24, the user might think. The search history 24 may comprise a memory in which the search terms may be stored from previous searches. In the present example, the input supplementing unit 22 takes in the search history 24 a matching keyword 26 ( "ABCDEF") and transmits it in a step S12 from the search history 24 14 to the input unit, the input unit 14 completes the partial input 20 on the display unit 18 to the found, matching keyword 26 and thus forms an input proposal 28 for the search term input by the user. the user can now accept this input proposal 28 when the place name fits. Instead of a single input proposal 28 also includes a list of multiple input images can be displayed. the user Takes the input proposal 28, so a search for a database entry in a known manner is performed term input on the basis of the search through the input unit 14 in a step S14.

For example, assume that a database record is located in the database 12 30, in which to the place name ( "ABCDEF") nor an address 32 ( "XYZ") is stored. The database entry 30 further includes still category data 34 (M1, M2). For example, the category data 34 may specify a category M1, in which the place name is arranged. For example, it can be a swimming pool or a gym, an airport or a restaurant. Just may be stored as a category M2, for example, that it is a location that is operated by a company with a specific company name. The address 34 and the category data 36, ​​metadata 38 constitute the database entry 30 to the place names 32 in the sense of the invention.

The Dätenbankeintrag 30 found is transferred to a step S16 to display a search result to the input unit 14 where it can then be displayed, for example, on the display unit 18, so that the user can acknowledge that it is the desired navigation destination.

Acknowledges to the user that it is the desired navigation destination, the metadata are transmitted 38 in a step S18 to the input supplementing unit 22, which then stores in a step S20, the metadata in the search history 24th

If the user is now in a subsequent search of the Bedieneinrich- tung 16, for example, the initial letters of the address 34 or, for example initial of M1 or M2, a matching keyword is also at this part entering back into the Search History 24 found then to is used to make an input proposal. This is possible even though the user has previously entered not the address 32 or category data 36th

So suggestions are collected in the Search History gradually adapted to the user. In summary, the inventive idea is that for once selected (not wanted, but already found and acknowledged by the user) search results metadata that are present on this search result, are also stored in a search history. The search history can be configured globally here, so for a search for each operating mode of the infotainment system, or even contextual, ie separately for example, telephony, navigation and media playback. Then the following search items parts of the metadata typed, so the metadata are proposed for the following search items if the letters already entered with on sluggish match in the metadata.

The search results as they are stored in the search history, are particular targets of a navigation system, so place names, street names, names of point-of-interests, brand names of operators of different locations, such as restaurants, and area types (restaurants, airports and the like) and styles (eg food type).

Preferably, the display of results from the search history is dependent upon a current geo-location, a predetermined region (EU, NAR North America) or an indication of the context in which wanted (navigation, phone book, etc.) or a prioritization criterion, that is, for example, which city ​​is the largest. In the hit list is preferably marked in color, which matches part of the matching search term from the search history with the input part.

A particularly preferred search in the Search History takes place at the phonemic level, gene to be taken into account different spelling variations.

Alternatively, or in addition to navigation data, the search results from the search history music data with artist, genre, song, station lists (transmitter) or telephone lists (call stacks, address books, favorites) are.

The total received so context-sensitive list of input proposals adapted always the more often the user uses the system better to a user.
