For example, when the user using the vehicle diagnostic service 240 confirms the vehicle abnormality warning message, the vehicle abnormality signal is transmitted to the service center server 300 by the wireless communication of the user terminal 400, 300 to receive a vehicle response signal indicating a countermeasure against the vehicle anomaly signal, and the display of the user terminal 400 may display a measure related to the vehicle anomaly state.

This vehicle diagnostic service 240 may be implemented as follows.

According to one example, when at least one of the elements constituting the check element list for the vehicle is abnormal, the vehicle may emit an acoustic wave signal including a vehicle state signal (vehicle anomaly signal). The smartphone receives the sound wave signal including the emitted vehicle abnormality signal, so that the user A can receive the warning of the vehicle abnormality through the smart phone. For example, a vehicle anomaly warning may generate a vibration or a sound with the message 'brake anomaly warning'. The user A can confirm the warning message. If the user requests the diagnosis of the vehicle abnormality to the nearest service center through the wireless communication of the smartphone, the user A can take appropriate measures from the service center. For example, as a countermeasure against a brake over warning, 'B car AS center. First release the parking brake. If it still does not turn off, there is a shortage of brake fluid in the engine compartment. Please go to the nearest repair shop and repair. "

Such a vehicle diagnostic service 240 can provide vehicle diagnostic information, and it is easy to provide information on maintenance, and it is possible to promptly provide maintenance information and surrounding service center information before a failure occurs. In addition, when a failure occurs, the driver can be notified of the failure so that quick response is possible.

Referring to the left table of FIG. 7, each symbol has a different meaning according to a predetermined frequency range in the non-audible frequency band. In the present invention, the non-audible frequency band of 16,000 Hz to 19,900 Hz can be utilized.

For example, symbol 6 in the non-audible frequency band is defined as a first frequency range with frequencies of 17578.13 Hz (F1) and 18843.75 Hz (F2), symbol 8 is defined as 17859.38 Hz (F1) frequency and 18843.75 Hz ) Frequency. ≪ / RTI >

Further, referring to the right table of FIG. 7, each symbol has a different meaning according to a predetermined frequency in an audible frequency band. In the present invention, it is possible to utilize the audible frequency band of from 7,000 Hz to 11,000 Hz to enhance the sound or to utilize the audible frequency band of 7,000 Hz to 16,000 Hz to increase the recognition rate.

For example, within the audible frequency band, symbol 7 is defined as the first frequency by the 6281.25 Hz (F) frequency and symbol 8 is defined by the second frequency by the frequency of 7312.50 Hz (F).

There is a difference that the same symbol 8 is defined as the second frequency range in the non-audible frequency band and the second frequency is defined in the audible frequency band.

The storage device of the user terminal may store a mapping table that predefines the relationship between symbol and frequency range. A plurality of symbols may be determined by the mapping table, and a sound wave signal including the determined symbols may be used in the soundqualistic system.

In this way, the soundqualistic system can quickly and stably provide a variety of vehicle services with a high recognition rate even in a noisy environment by using a sound signal including a predetermined symbol in the non-audible frequency band or the audible frequency band.

For example, according to the result of experiment in the environment where 60dB of noise is generated as in the general assumption, it was possible to provide the car service with the recognition rate of 99% for the vehicle located within 3m of the user terminal, Respectively.

8 is a diagram showing an example in which the packet structure shown in FIG. 6 is used for a vehicle service.

8, "PN1A" in the header can mean ver.1A for Pilot Navi, "+ /" in the tail can mean termination, and the combination of header, data, , The object to be controlled, or the definition table.

If the data includes " 05 " in the data as shown in FIG. 8A, it can perform substantially the same function as the volume reduction button of the remote controller. If the data includes " 22 " It is possible to perform substantially the same functions as those described above.

If the data includes " 35 " in the data as shown in FIG. 8C, the path canceling control can be performed on the navigation apparatus. If the data includes " 52 "Quot; 61 " is included in the data as shown in FIG. 8E, the video device can be terminated.

It will be readily appreciated that a variety of electronic devices, including remote controllers, DMBs, navigation devices, audio and video devices, are connected to the vehicle in wired and wireless fashion and that the characters in each data can be varied.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
