Abstract

A system and a method are provided for navigating an arrangement of transportation, for example, a vehicle, an aircraft, a motor vehicle, or a ship, from at least one location to at least one destination, which minimize the demand on memory capacity required for voice recognition and conversion, the voice data entry being compared with subsets, for example, with sequential segments or with successive subsets of the navigation database elements stored in the memory unit.

Claims

1. A system for navigating an arrangement for transportation from at least one location to at least one destination, the system comprising:

at least one input device for entering at least one of the following;

a) a command,

b) the at least one location, and

c) the at least one destination; and

at least one voice data entry module assigned to the input device, the voice data entry module operable to recognize at least one voice data entry and convert the voice data entry into at least one corresponding system entry, the voice data entry module including;

a) at least one memory unit for storing elements of at least one navigation database,

b) a comparator for assigning at least one of the elements of the navigation database to the voice data entry in accordance with a comparison of the voice data entry with subsets, and

c) a routing arrangement for routing the assigned element to the system as at least one of a command, a location, and a destination.

2. The system according to claim 1, wherein the arrangement for transportation includes one of a vehicle, an aircraft, a motor vehicle, and a ship.

3. The system according to claim 1, wherein the elements of the at least one navigation database include at least one of command names, place names, street names, and points of interest.

4. The system according to claim 1, wherein the subsets include one of sequential segments and successive subsets of the elements stored in the memory unit.

5. The system according to claim 3, wherein the command names, the place names, the street names, and the points of interest are stored in the subsets according to one of the following:

a) at least one pattern of order, and

b) an assigned probability.

6. The system according to claim 5, wherein the at least one pattern of order includes an alphabetic pattern of order.

7. The system according to claim 1, wherein the voice data entry module is one of:

a) integrated into the system, and

b) located outside of the system and linked to the system.

8. The system according to claim 7, wherein the voice data entry module is connected to the system in one of the following ways:

a) via at least one data bus,

b) via at least one other electrical bus, and

c) via at least one optical interface.

9. The system according to claim 8, wherein the at least one data bus includes a Controller Area Network and the at least one optical interface includes at least one optical waveguide.

10. The system according to claim 1, wherein the memory unit includes at least one of a Compact Disc and a Digital Versatile Disc, and wherein the voice data entry module includes at least one of a Compact-Disc reading device and a Digital-Versatile-Disc reading device.

11. The system according to claim 1, wherein the memory unit includes at least one of a card unit and one other memory unit, and wherein the voice data entry module includes at least one of a data input unit and a card reading device.

12. The system according to claim 11, wherein the at least one card unit includes at least one of a PCMCIA-card and an ISO card.

13. A method for navigating an arrangement for transportation from at least one location to at least one destination, the method comprising the steps of:

entering, using at least one input device, at least one of the following;

a) a command,

b) the at least one location, and

c) the at least one destination;

performing a voice recognition via at least one voice data entry module in the input device, wherein at least one voice data entry is converted to at least one corresponding system input;

making elements of at least one navigation database available in at least one memory unit;

assigning at least one of the elements of the navigation database to the voice data entry in accordance with a comparison of the voice data entry with subsets, the comparison being performed by a comparator; and

routing the assigned element to the system as at least one of a command, a location, and a destination.

14. The method according to claim 13, wherein the arrangement for transportation includes one of a vehicle, an aircraft, a motor vehicle and a ship.

15. The method according to claim 13, wherein the elements of the at least one navigation database include at least one of command names, place names, street names, and points of interest.

16. The method according to claim 13, wherein the subsets include one of sequential segments and successive subsets of the elements stored in the memory unit.

17. The method according to claim 13, wherein results of respective comparisons are temporarily stored until a final evaluation.

18. The method according to claim 15, wherein the command names, the place names, the street names, and the points of interest are stored in the subsets according to one of the following:

a) at least one pattern of order, and

b) an assigned probability.

19. The method according to claim 18, wherein the at least one pattern of order includes an alphabetic pattern of order.

20. The method according to claim 13, wherein a recognized voice data entry is transmitted to the system in one of the following ways:

a) via at least one data bus,

b) via at least one other electrical bus, and

c) via at least one optical interface.

21. The method according to claim 20, wherein the at least one data bus includes a Controller Area Network and the at least one optical interface includes at least one optical waveguide.

22. The method according to claim 13, wherein the elements of the navigation database are stored on at least one of a Compact Disc and a Digital Versatile Disc.

23. The method according to claim 13, wherein the elements of the navigation database are stored in the input device on at least one of a PCMCIA-card, an ISO card, and one other memory unit.
