5, the user (specifically, the driver) operates the first input unit 111 to drive the wiper 20 (step 200) so as to wipe off the water flowing through the windshield 17 when snow or rain is present during operation.

As the wiper 20 is driven, the water flowing through the windshield 17 is wiped off and the driver can secure a field of view.

Then, the driver operates the second input unit 112 to drive the audio device 55 (202) in order to listen to the music broadcasted in the favorite music or radio program.

As the audio device 55 is driven, a sound source is output to the vehicle 1, and the driver is driving while listening to the music.

However, if the driving cycle of the wiper 20 and the beat of the sound source do not coincide with each other when the user is listening to the music while driving the wiper 20, the driver can not listen to music by concentrating on the music.

At this time, the driver inputs the timing synchronization signal to the control unit 130 by operating the time synchronization button of the third input unit 113 in order to concentrate and listen to the music by aligning the driving cycle of the wiper 20 with the timing of the sound source (step 204) .

Accordingly, the beat extraction unit 140 receives the control signal from the control unit 130, extracts the beat of the currently reproduced sound source through the audio device 55, and transmits the beat of the extracted sound source to the control unit 130 (206).

Then, the control unit 130 transmits a wiper drive signal to the wiper module 150 to change the driving period of the wiper 20 according to the beat of the extracted sound source.

Accordingly, the wiper module 150 calculates 208 the driving period of the wiper 20 using the beat of the sound source currently reproduced through the audio device 55, and outputs the driving period of the wiper 20 to the audio device 55 (210) in accordance with the beat of the sound source output through the sound source.

Accordingly, the driving cycle of the wiper 20 is synchronized with the beat of the sound source reproduced by the audio device 55, so that the user of the driver or the like can listen to music by using the wiper 20, (212).

In step 214, it is determined whether the sound source output through the audio device 55 has been changed while listening to the music by synchronizing the driving cycle of the wiper 20 with the beat of the sound source reproduced by the audio device 55.

If it is determined in step 214 that the sound source of the audio device 55 is changed, the control unit 130 transmits a control signal for extracting the changed sound source to the beat extraction unit 140.

Accordingly, the beat extraction unit 140 receives the control signal from the control unit 130, extracts the beat of the changed sound source, and transmits the beat of the extracted sound source to the control unit 130 (216).

The control unit 130 feeds back to the step 208 to change the driving period of the wiper 20 in accordance with the beat of the changed sound source, and proceeds with the subsequent operation.

Accordingly, the wiper module 150 recalculates the driving cycle of the wiper 20 using the beat of the changed sound source through the audio device 55, and changes the driving cycle of the wiper 20 to match the beat of the changed sound source The operation is repeated.
