Abstract

A user device includes a storage device that stores a program for a vehicular service, a signal generation unit that generates a certain sound wave signal depending on the vehicular service, and a signal emission unit that emits the generated sound wave signal. When one component of a vehicle receives and recognizes the emitted sound wave signal, the vehicle provides the vehicular service based on the emitted sound wave signal.

Claims

1. A user device, comprising:

a storage device that stores a program for a vehicular service;

a signal generation unit that generates a certain sound wave signal depending on the vehicular service; and

a signal emission unit that emits the generated sound wave signal,

wherein when one component of a vehicle receives and recognizes the emitted sound wave signal, the vehicle provides the vehicular service based on the emitted sound wave signal.

2. The user device of claim 1,

wherein if the vehicular service is plural in number, the signal generation unit generates a sound wave signal corresponding to a certain vehicular service selected by a user.

3. The user device of claim 1, further comprising:

a signal reception device that receives, from the vehicle, a feedback sound wave signal generated in response to the emitted sound wave signal; and

a display unit that displays certain information included in the feedback sound wave signal on a screen thereof.

4. The user device of claim 1, further comprising:

a communication device that transmits, to a server, a search signal generated as destination search is conducted by a user for a navigation service among the vehicular services, and receives, from the server, a search result signal indicating a result of the destination search,

wherein the signal generation unit generates a sound wave signal including the search result signal, and

the vehicle provides the navigation service based on the sound wave signal including the search result signal.

5. The user device of claim 1, further comprising:

a communication device that receives a location signal including certain location information from another device or server for a navigation service among the vehicular services,

wherein the signal generation unit generates a sound wave signal including the location signal, and

the vehicular provides the navigation service based on the sound wave signal including the location signal.

6. The user device of claim 1, further comprising,

an input device that generates a convenience control signal as at least one of seat setting, mirror setting, and steering wheel setting is selected by a user for a driving convenience service among the vehicular services,

wherein the signal generation unit generates a sound wave signal including the convenience control signal, and

the vehicle provides the driving convenience service based on the sound wave signal including the convenience control signal.

7. The user device of claim 6,

wherein the seat setting includes an angle and height of a seat, distance between a pedal and a seat, and a temperature of a seat,

the mirror setting includes a position of a room mirror, and positions of side mirrors, and

the steering wheel setting includes a position and a temperature of a steering wheel.

8. The user device of claim 1, further comprising:

an input device that generates an air-conditioning control signal as setting for an air-conditioning device of a vehicle is conducted by a user for an air-conditioning control service among the vehicular services,

wherein the signal generation unit generates a sound wave signal including the air-conditioning control signal, and

the vehicle provides the air-conditioning control service based on the sound wave signal including the air-conditioning control signal.

9. The user device of claim 8,

wherein the setting for the air-conditioning device includes temperatures of an air-conditioner and a heater, and a temperature, humidity, and ventilation in the interior of the vehicle.

10. The user device of claim 1,

wherein the sound wave signal comprises a plurality of symbols,

the symbols indicate different meanings depending on a certain frequency within an inaudible frequency band or combination of a plurality of frequencies within an inaudible frequency band, and

the storage device stores a mapping table, which pre-defines relationship between the symbols and the certain frequency or relationship between the symbols and the combination of the frequencies.

11. The user device of claim 1,

wherein the sound wave signal comprises a plurality of symbols,

the symbols indicate different meanings depending on a certain frequency within an audible frequency band, and

the storage device stores a mapping table, which pre-defines relationship between the symbols and the certain frequency.

12. A user device, comprising:

a storage device that stores a program for a vehicular service;

a signal reception device that receives a certain sound wave signal emitted from a vehicle; and

a processor that searches a vehicular service corresponding to the received sound wave signal to implement certain operation for the searched vehicular service.

13. The user device of claim 12,

wherein if the searched vehicular service is a vehicle diagnosis service, the processor extracts a vehicle state signal from the sound wave signal, and

if at least one of a plurality of factors composing a check factor list for the vehicle is abnormal, the vehicle state signal includes a vehicle abnormality signal generated in the vehicle.

14. The user device of claim 12,

wherein if the searched vehicle service is a vehicle diagnosis service, the processor extracts a vehicle state signal from the sound wave signal, and

the vehicle state signal comprises at least one of fuel information, oil information, internal temperature information and driving information.

15. The user device of claim 12, further comprising:

a display unit that displays certain information corresponding to the certain operation.

16. The user device of claim 13, further comprising:

a communication device that transmits the vehicle abnormality signal to a server, and receives a vehicle response signal indicating a responsive measure to the vehicle abnormality signal from the server.

17. The user device of claim 12,

wherein when the sound wave signal is received, the processor is controlled to generate certain sound or vibration.

18. The user device of claim 12,

wherein the sound wave signal comprises a plurality of symbols,

the symbols indicate different meanings depending on a certain frequency within an inaudible frequency band or combination of a plurality of frequencies within an inaudible frequency band, and

the storage device stores a mapping table, which pre-defines relationship between the symbols and the certain frequency or relationship between the symbols and the combination of the frequencies.

19. The user device of claim 12,

wherein the sound wave signal comprises a plurality of symbols,

the symbols indicate different meanings depending on a certain frequency within an audible frequency band, and

the storage device stores a mapping table, which pre-defines relationship between the symbols and the certain frequency.

20. A method for providing a vehicular service by using a sound QR system, the method comprising:

storing a program for a vehicular service;

receiving a certain sound wave signal emitted from a mobile device; and

searching a vehicular service corresponding to the received sound wave signal to implement certain operation for the searched vehicular service,

wherein the certain sound wave signal is transmitted through an inaudible or audible frequency band, and differently generated in the mobile device depending on the vehicular service.
