Abstract

For the input of navigational target data into a navigation system by way of a facility for a mobile radio voice link, voice signals or signals derived therefrom, transmitted via the mobile radio voice link, are processed by a voice recognition device for recognizing spoken words. By way of at least one word recognized during this process, a comparison of targets with navigational target entries in a navigation database takes place. In the case of a positive result of the comparison, the corresponding navigational target entry is provided for input as navigation target in the navigation system.

Claims

1. A method of inputting navigational target data into a navigation system of a vehicle via a mobile communication device disposed in the vehicle, the method comprising the acts of:

processing, via a voice recognition device in the navigation system, voice signals received from the mobile communication device via a mobile radio voice link in order to recognize spoken words from a user of the navigation system as the navigational target data;

based on at least one word recognized during the processing act, comparing the navigational target data with navigational target entries stored in a navigation database in the navigation system;

when the navigational target data matches a particular navigational target entry from the comparing act, automatically accepting the particular navigational target entry as a navigation target in the navigation system without an input by the user;

when the navigational target data fails to match a particular navigational target entry from the comparing act, requesting an input from the user to accept or reject a potential navigational target, and, if the user does not accept or reject the potential navigational target within a predetermined time, automatically rejecting the potential navigational target entry as the navigation target in the navigation system;

displaying the particular navigational target entry on a display in the vehicle;

presetting at least one output rule for outputting the navigational target entry on the display; and

presetting at least one comparison rule for use in the act of comparing the navigational target data with navigational target entries based on the at least one word recognized by the voice recognition device;

wherein the navigational target entries include a category of the navigation target, the category corresponds to a point-of-interest, and the at least one word recognized by the voice recognition device is compared to the category of the point-of-interest and compared to a name of the point-of-interest.

2. The method according to claim 1, wherein:

in addition to comparing the navigational target data with the navigational target entries, the method further comprises performing a keyword comparison between at least one spoken word recognized by the voice recognition device and at least one navigational keyword stored in a database.

3. The method according to claim 2, wherein for comparing the at least one spoken word with the at least one navigational keyword, the method uses at least two spoken and recognized words which, in the spoken context, have a predetermined minimum distance and/or a predetermined maximum distance from one another.

4. The method according to claim 1, wherein for comparing the targets with the navigational target entries by means of the at least one word recognized by the voice recognition device, the method uses at least two spoken and recognized words which, in the spoken context, have a predetermined minimum distance and/or a predetermined maximum distance from one another.

5. The method according to claim 1, further comprising the act of selecting, via an input unit, the particular navigational target entry output on the display.

6. The method according to claim 1, further comprising the act of presetting at least one comparison rule for use in the act of comparing the navigational target data with navigational target entries based on the at least one word recognized by the voice recognition device.

7. The method according to claim 1, wherein an order of the spoken words is optionally taken into consideration in the comparing act.

8. The method according to claim 1, wherein, when requesting the input from the user to accept or reject the potential navigational target, a countdown indicating an amount of time left in the predetermined time is displayed on the display.

9. The method according to claim 1, further comprising, when an additional navigation target is recognized after selection of the navigation target, presenting an option to the user to select the additional navigation target as a new intermediate target along a route to the navigation target.

10. An input system for input of navigational target data into a navigation system of a vehicle via a mobile communication device disposed in the vehicle, comprising:

a voice recognition device disposed in the navigation system and configured to process voice signals received from the mobile communication device via a mobile radio voice link, the voice recognition device recognizing spoken words from a user of the navigation system as the navigational target data;

a target comparison device configured to compare at least one word recognized by the voice recognition device with navigational target entries stored in a navigation database in the navigation system, wherein

when the target comparison device matches the at least one word recognized by the voice recognition device to a particular navigational target entry, the target comparison device automatically accepts the particular navigational target entry as a navigation target in the navigation system without an input by the user; and

a display disposed in the vehicle that displays the particular navigational target entry;

wherein, when the navigational target data fails to match a particular navigational target entry from the comparing act, the target comparison device requests an input from the user to accept or reject a potential navigational target, and, if the user does not accept or reject the potential navigational target within a predetermined time, the target comparison device automatically rejects the potential navigational target entry as the navigation target in the navigation system;

wherein at least one output rule for outputting the navigational target entry on the display is preset;

wherein at least one comparison rule for use in the act of comparing the navigational target data with navigational target entries is preset based on the at least one word recognized by the voice recognition device; and

wherein the navigational target entries include a category of the navigation target, the category corresponds to a point-of-interest, and the at least one word recognized by the voice recognition device is compared to the category of the point-of-interest and compared to a name of the point-of-interest.

11. The input system according to claim 10, wherein an order of the spoken words is optionally taken into consideration when the target comparison device compares the at least one word recognized by the voice recognition device with the navigational target entries stored in the navigation database.

12. The input system according to claim 10, wherein, when the target comparison device requests the input from the user to accept or reject the potential navigational target, a countdown indicating an amount of time left in the predetermined time is displayed on the display.

13. The input system according to claim 10, wherein, when an additional navigation target is recognized after selection of the navigation target, an option is presented to the user to select the additional navigation target as a new intermediate target along a route to the navigation target.

14. A vehicle, comprising:

a navigation system into which is input navigational target data;

a mobile communication device;

wherein the navigation system includes;

a mobile radio voice link associated with the vehicle that receives voice signals from the mobile communication device; and
