Abstract

A vehicle and a method for controlling the same are provided. In particular, linking information of a broadcast signal having been output during a turn-off mode is transmitted to a DAB receiver upon receiving a turn-on signal. The vehicle includes a Digital Audio Broadcasting (DAB) receiver that is configured to receive a first DAB signal that corresponds to a selected first broadcast signal. In addition, a speaker outputs the first broadcast signal based on the received first DAB signal or a first frequency-modulation (FM) signal corresponding to the first broadcast signal. In response to receiving a turn-on signal, a controller transmits linking information of the first broadcast signal from among linking information of a plurality of broadcast signals to the DAB receiver to output the first broadcast signal output during a turn-off mode.

First claim

What is claimed is:

1. A vehicle, comprising:
a Digital Audio Broadcasting (DAB) receiver configured to receive a first DAB signal that corresponds to a selected first broadcast signal;
a speaker configured to output the first broadcast signal based on the received first DAB signal or a first frequency-modulation (FM) signal that corresponds to the first broadcast signal; and
a head unit configured to transmit linking information of the first broadcast signal from among linking information of a plurality of broadcast signals to the DAB receiver in response to receiving a turn-on signal, to output the first broadcast signal been output during a turn-off mode.

2. The vehicle according to claim 1 , wherein after receiving the linking information of the first broadcast signal from the head unit, the DAB receiver is configured to transmit an acknowledgement (ACK) signal to the head unit.

3. The vehicle according to claim 2 , wherein after receiving the acknowledgement (ACK) signal from the DAB receiver, the head unit is configured to transmit linking information of the remaining broadcast signals other than the first broadcast signal to the DAB receiver.

4. The vehicle according to claim 3 , wherein when a second broadcast signal is selected during transmission of the linking information of the remaining broadcast signals other than the first broadcast signal, the head unit is configured to determine transmission or non-transmission of linking information of the second broadcast signal.

5. The vehicle according to claim 4 , wherein the head unit is configured to first transmit the linking information of the second broadcast signal from among the remaining broadcast signals other than the first broadcast signal, in response to determining that the linking information of the second broadcast signal is not transmitted to the DAB receiver.

6. The vehicle according to claim 1 , wherein the linking information includes frequency-modulation (FM) frequency information for receiving an FM signal used to output a corresponding broadcast signal.

7. The vehicle according to claim 1 , wherein when intensity of the received first DAB signal is equal to or less than a predetermined threshold value, the DAB receiver is configured to confirm a first FM frequency from the linking information of the first broadcast signal.

8. The vehicle according to claim 7 , further comprising:
a frequency-modulation (FM) receiver configured to receive the first FM signal that corresponds to the first broadcast signal using the confirmed first FM frequency.

9. The vehicle according to claim 8 , wherein the head unit is configured to operate the speaker to output the first broadcast signal based on the first FM signal received by the FM receiver.

10. The vehicle according to claim 1 , wherein the head unit includes a head unit storage unit configured to store linking information of the plurality of broadcast signals upon receiving a turn-off signal.

11. The vehicle according to claim 10 , wherein the head unit storage unit is configured to store linking information of the plurality of broadcast signals including the first broadcast signal.

12. The vehicle according to claim 10 , wherein the head unit further includes: a controller configured to transmit linking information of the first broadcast signal output during the turn-off mode from among the linking information of the plurality of broadcast signals stored in the head-unit storage unit to the DAB receiver, in response to receiving the turn-on signal.

13. A method for controlling a vehicle that includes a Digital Audio Broadcasting (DAB) receiver configured to receive a first DAB signal that corresponds to a selected first broadcast signal, the method comprising:
terminating, by a head unit, an output of a first broadcast signal in response to receiving a turn off signal;
transmitting, by the head unit, linking information of the first broadcast signal from among linking information of a plurality of broadcast signals to the DAB receiver in response to receiving a turn-on signal; and
outputting, by the head unit, the first broadcast signal using the first DAB signal or a first frequency-modulation (FM) signal obtained based on the linking information of the first broadcast signal.

14. The method according to claim 13 , further comprising:
transmitting, by the DAB receiver, an acknowledgement (ACK) signal to the head unit in response to receiving the linking information of the first broadcast signal stored in a head unit storage unit.

15. The method according to claim 14 , further comprising:
transmitting, by the head unit, linking information of the remaining broadcast signals other than the first broadcast signal to the DAB receiver, in response to receiving the acknowledgment (ACK) signal.

16. The method according to claim 15 , wherein the transmitting of the linking information of the remaining broadcast signals other than the first broadcast signal to the DAB receiver includes:
when a second broadcast signal is selected while the linking information of the remaining broadcast signals other than the first broadcast signal is transmitted to the DAB receiver, determining, by the head unit, whether linking information of the second broadcast signal is transmitted to the DAB receiver.

17. The method according to claim 16 , wherein the transmitting of the linking information of the remaining broadcast signals other than the first broadcast signal to the DAB receiver includes:
first transmitting, by the head unit, linking information of the second broadcast signal from among the remaining broadcast signals other than the first broadcast signal in response to determining that the linking information of the second broadcast signal is not transmitted to the DAB receiver.

18. The method according to claim 13 , wherein the linking information includes frequency-modulation (FM) frequency information for receiving an FM signal used to output a corresponding broadcast signal.

19. The method according to claim 13 , wherein the outputting of the first broadcast signal includes:
selecting, by the head unit, any one of the first DAB signal or the first FM signal in response to intensity of the first DAB signal.

20. The method according to claim 19 , wherein the outputting of the first broadcast signal includes:
confirming, by the head unit, a first FM frequency based on the linking information of the first broadcast signal when the intensity of the received first DAB signal is equal to or less than a predetermined threshold value.

21. The method according to claim 20 , wherein the outputting of the first broadcast signal further includes:
receiving, by the head unit, the first frequency-modulation (FM) signal that corresponds to the first broadcast signal using the confirmed first FM frequency.

22. The method according to claim 21 , wherein the outputting of the first broadcast signal further includes:
outputting, by the head unit, the first broadcast signal based on the first FM frequency.

23. The method according to claim 13 , further comprising:
storing, by the head unit, the linking information of the plurality of broadcast signals in a head unit storage unit in response to receiving the turn-off signal.

24. The method according to claim 23 , wherein the storing of the linking information of the plurality of broadcast signals includes:
storing, by the head unit, linking information of the plurality of broadcast s
