Abstract

A system for diagnosing a vehicle terminal includes a WiFi dongle coupled to an external connection terminal of a vehicle to connect wireless communication between a vehicle diagnosis device and the vehicle terminal. A vehicle diagnosis device is configured to transmit an inspection start command to the vehicle terminal through the WiFi dongle, and inspect at least one of a Bluetooth function and a voice recognition function. The vehicle terminal is configured to download and store phone book data through Bluetooth paired with the vehicle diagnosis device, detect a phone book name in the stored phone book data, and enter a call making mode. The vehicle diagnosis device inspects the Bluetooth function according to whether the phone book data of the vehicle terminal is downloaded, and inspects the voice recognition function.

Claims

1. A system for diagnosing a vehicle terminal which is a multimedia product assembled in a vehicle assembly plant, the system comprising:

an IEEE 802.11 dongle coupled to an external connection terminal of a vehicle to connect wireless communication between a vehicle diagnosis device and the vehicle terminal, wherein

the vehicle diagnosis device is configured to transmit an inspection start command to the vehicle terminal through the IEEE 802.11 dongle and to inspect at least one of an IEEE 802.15.1 function and a voice recognition function in consideration of system information received from the vehicle terminal,

the vehicle terminal is configured to download and store phone book data through IEEE 802.15.1 paired with the vehicle diagnosis device, to detect a phone book name spoken with a voice from the vehicle diagnosis device in the stored phone book data, and to enter a call making mode, and

wherein the vehicle diagnosis device inspects the IEEE 802.15.1 function according to whether the phone book data of the vehicle terminal is downloaded, and inspects the voice recognition function according to whether the vehicle terminal enters the call making mode.

2. The system of claim 1, wherein the system information includes at least one of multimedia product classification information, classification information on a basic language applied to a multimedia product, IEEE 802.15.1 inspection application classification information, and voice recognition inspection application classification information.

3. The system of claim 1, wherein the vehicle diagnosis device provides the phone book name appropriate to a corresponding language through a voice speaker with reference to classification information on a basic language applied to the system information.

4. The system of claim 1, wherein the vehicle diagnosis device transmits the phone book data to the vehicle terminal when the IEEE 802.15.1 is connected with the vehicle terminal through pairing.

5. The system of claim 1, wherein the vehicle terminal matches a list of vehicle diagnosis devices used in the vehicle assembly plant with Mac addresses and stores the matched vehicle diagnosis devices and the Mac addresses, and performs IEEE 802.15.1 pairing with the vehicle diagnosis device through the Mac addresses stored in the list.

6. The system of claim 1, wherein when the vehicle terminal receives a voice recognition inspection start command from the vehicle diagnosis device, the vehicle terminal switches to a voice recognition standby mode, recognizes the phone book name spoken by the vehicle diagnosis device, and detects the phone book name from the phone book data.

7. The system of claim 1, wherein the vehicle diagnosis device transmits the inspection start command to the vehicle terminal through a wired cable connected to an on-board diagnostics (OBD) terminal, and initiates the diagnosis of the IEEE 802.15.1 and the voice recognition function.

8. The system of claim 2, wherein the multimedia product classification information includes audio, video, and navigation (AVN) information.

9. The system of claim 2, wherein the vehicle diagnosis device provides the phone book name appropriate to a corresponding language through a voice speaker with reference to the classification information on the basic language applied to the system information.

10. A method of diagnosing a vehicle terminal which is a multimedia product assembled in a vehicle assembly plant by a vehicle diagnosis device, the method comprising steps of:

a) connecting wireless communication with the vehicle terminal through an IEEE 802.11 dongle coupled to an external connection terminal of a vehicle, and transmitting an inspection start command to the vehicle terminal;

b) connecting to IEEE 802.15.1 according to a request of the vehicle terminal, and transmitting stored phone book data to the vehicle terminal through IEEE 802.15.1 communication;

c) determining that an inspection of the IEEE 802.15.1 is successful when receiving a phone book data reception completion message from the vehicle terminal; and

d) speaking a phone book name for a call making command through a voice output speaker, and determining that an inspection of the voice recognition function is successful when the vehicle terminal detects the phone book name from the phone book data and enters a call making mode.

11. The method of claim 10, wherein step a) includes:

recognizing information on a basic language applied to a multimedia product, and whether the inspection of the IEEE 802.15.1 or the voice recognition is applied based on system information received from the vehicle terminal.

12. The method of claim 10, wherein step d) includes:

selecting and speaking the phone book name according to a basic language applied to the vehicle terminal among phone book names stored in the phone book data.

13. The method of claim 10, further comprising after step (d):

storing vehicle identification information on a diagnosed vehicle or identification information and an inspection history of the vehicle terminal.

14. The method of claim 11, wherein step d) includes:

selecting and speaking the phone book name according to the basic language applied to the vehicle terminal among phone book names stored in the phone book data.

20. The system of claim 14, wherein the multimedia product classification information includes audio, video, and navigation (AVN) information.

15. A method of diagnosing an IEEE 802.15.1 function and a voice recognition function by interconnecting a vehicle terminal, which is a multimedia product assembled in a vehicle assembly plant with a vehicle diagnosis device, the method comprising steps of:

a) receiving, by the vehicle terminal, an inspection start command from the vehicle diagnosis device connected through an IEEE 802.11 dongle, and initiating a diagnosis mode;

b) detecting the vehicle diagnosis device and a Mac address stored in a system for diagnosing the vehicle terminal, requesting IEEE 802.15.1 pairing with the vehicle diagnosis device through the detected Mac address, and connecting the vehicle diagnosis device and the IEEE 802.15.1;

c) downloading and storing phone book data transmitted from the vehicle diagnosis device through IEEE 802.15.1 communication, and transmitting a phone book data reception completion message; and

d) recognizing a phone book name spoken by the vehicle diagnosis device and searching for the recognized phone book name in the stored phone book data, and transmitting a result of a success of entrance to a call making mode by using a telephone number of the phone book name to the vehicle diagnosis device.

16. The method of claim 15, wherein step b) includes:

receiving and storing the Mac address through the inspection start command, and then searching for the vehicle diagnosis device.

17. The method of claim 15, wherein step d) includes:

entering a voice recognition standby mode when receiving a voice recognition inspection start command from the vehicle diagnosis device, and transmitting a voice recognition standby mode state to the vehicle diagnosis device.

18. The method of claim 15, wherein the phone book data includes the phone book name and the telephone number for at least one language.

19. The method of claim 15, wherein after step d), further comprising:

deleting, by the vehicle terminal, the stored phone book data for diagnosing the IEEE 802.15.1 and the voice recognition and removing a test trace.
