BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for supporting a high-speed search function of a vehicle AVN system,

The present invention relates to an apparatus and method for supporting a fast search function. More particularly, the present invention relates to an apparatus and method for supporting a high-speed search function in an AVN (Audio Video Navigation) system for a vehicle.

Conventionally, when you turn the TUNE knob in the car audio or AVN, the file is searched and the desired file name is displayed. Press the TUNE knob to play the file. Each time you turn the knob, the previous or next one is skipped.

However, if you turn the TUNE knob to move to the previous or next song, if the number of songs is large, it takes a lot of time to find the desired song. For example, if you are currently listening to aOOOO.mp3 and want to find bOOOO.mp3, then aOOOO.mp3 is the first file and bOOOO.mp3 is the 1000th file. I can find it.

Meanwhile, conventionally, when a song is searched by the TUNE knob while driving, it is difficult to see the current searched song because it is difficult to view the screen.

Korean Patent Laid-Open Publication No. 2014-0051631 proposes a multimedia search apparatus for a vehicle AVN system. However, the above-described problem can not be solved because the device merely indexes media files in an integrated manner.

1 is a block diagram schematically showing an apparatus for supporting a multimedia file search function of a vehicle AVN system according to an embodiment of the present invention.

The multimedia file search function supporting device 100 is a device that supports a first unit search function using a TUNE knob in song search in an AVN system for a vehicle.

The multimedia file search function supporting device 100 enables a user to quickly and easily search for a desired song when searching for a song using the TUNE knob while playing a song in AVN as follows.

First, each time you turn the knob to search for songs with the TUNE knob, you can skip to the next or previous song, but skip to the beginning.

Second, when turning the knob to move to the next or previous song, when the beginning of the song name is changed, the beginning of the song is informed by voice guidance so that the user can check how much the current song is being searched.

Third, stop turning the knob and after a certain period of time, the currently selected file name is informed by voice guidance so that the user can check what the currently searched file is, without looking at the screen during operation.

Referring to FIG. 1, an apparatus 100 for supporting a multimedia file search function includes an input unit 110, a microcomputer (MICOM) 120, and a CPU 130.

The input unit 110 includes various hard keys in the AVN head unit, a TUNE knob, and the like. The input unit 110 transmits an event generated by a hard key, a TUNE knob or the like to the microcomputer 120.

The microcomputer 120 performs a function of processing a hard key input in the AVN. The microcomputer 120 also functions to process communication with the AVN external module.

The CPU 130 includes various programs operated on the OS. The CPU 130 controls the radio, the CD, the MP3 player, and the navigation system using these programs.

The multimedia file search function supporting apparatus 100 is used for searching for a song. In consideration of this point, the CPU 130 can perform a function of controlling the MP3 player. However, the control function of the CPU 130 in this embodiment is not limited to the MP3 player.

Next, various operation methods of the multimedia file search function supporting apparatus 100 will be described with an example.

Example 1) When the knob is turned and held

■ If the song currently being played starts with A

- When turning the knob to the right

: Go to the first song that starts with B. (If there is no song starting with B, the next alphabet start song)

: B is announced. (Other alphabets are the same)

- When turning the knob to the left

: Go to the first song starting with Z. (If there is no song starting with Z, the previous alphabet starting song)

: Z is spoken. (Other alphabets are the same)

■ If the currently playing song is a song that starts with a

- When turning the knob to the right

: Go to the first song that starts with b. (If you do not have a song that starts with a,

: L voice guidance. (The same for other initiators)

- When turning the knob to the left

: I go to the first song that starts with. (If you do not have a song that starts with a heh,

: I will give you a voice. (The same for other initiators)

Example 2) Turning the knob without pressing the knob

■ If the song currently being played starts with A

- When turning the knob to the right

: If the song starts with the next song A, it will not give any guidance.

: If the next song is a song that starts with B, voice will be spoken. (Other alphabets are the same)

- When turning the knob to the left

: If the song starts with the previous song A, it will not guide you.

: If the previous song is a song starting with Z, say "Z". (Other alphabets are the same)

■ If the currently playing song is a song that starts with a

- When turning the knob to the right

: If the next song begins with a, it will not guide you.

: If the next song starts with b, voice will be announced. (The same for other initiators)

- When turning the knob to the left

: If the previous song starts with a, it will not guide you.

: If the previous song starts with a heh, he will voice a voice. (The same for other initiators)

As described above, the multimedia file search function supporting device 100 does not jump to the previous or next music by turning the knob while holding the TUNE knob, but proceeds to the next music piece or the beginning music of the previous music.

When the operation of turning the TUNE knob is stopped, the multimedia file search function support apparatus 100 displays the searched file on the screen and confirms whether the TUNE knob operation is performed again within a predetermined time in this state.

When the TUNE knob operation is not performed again within a predetermined time (for example, 0.5 second) after the TUNE knob operation is stopped, the apparatus 100 for searching for multimedia file searches for the currently displayed file name on the screen. At this time, the multimedia file search function support device 100 voices voice as music.mp3 if it is searched. However, if the file name is too long, voice guidance is given only for a certain length. For example, the multimedia file search function supporting apparatus 100 provides voice guidance within 10 characters.

When the TUNE knob operation is performed again within a predetermined time, the apparatus 100 for supporting the multimedia file search function does not provide voice guidance.

On the other hand, the multimedia file search function supporting apparatus 100 can search for a file by turning the TUNE knob and play the corresponding file by pressing the TUNE knob while a desired file name is displayed.

Meanwhile, the multimedia file search function supporting device 100 stops turning the knobs when searching for a track / channel / file with the TUNE knob during playback of a CD, DMB, radio, or MP3 in the AVN, So that the user can check which track / channel / file is currently searched so that the user can easily find a desired track / channel / file without looking at the screen during operation. Hereinafter, this will be described in more detail.

When the operation of turning the TUNE knob is stopped, the device 100 for searching multimedia file search function displays the track / channel / file searched on the screen and confirms whether the TUNE knob operation is performed again within a predetermined time in this state.

If the TUNE knob operation is not performed again within a predetermined time (for example, 0.5 second) after the TUNE knob operation is stopped, the apparatus 100 for searching for a multimedia file searches for the currently displayed track / channel / file name on the screen. At this time, the multimedia file search function support device 100 voices voice as music.mp3 if it is searched. However, if the file name is too long, only a certain length of voice guidance is given. For example, only up to 10 characters are spoken.

When the TUNE knob operation is performed again within a predetermined time, the apparatus 100 for supporting the multimedia file search function does not provide voice guidance.

When the multimedia file search function supporting device 100 is searched and a desired file name is displayed, the corresponding track / channel / file is reproduced by pressing the TUNE knob.

2 is a flowchart illustrating an operation method of a multimedia file search function supporting apparatus of a vehicle AVN system according to an embodiment of the present invention.

First, when the TUNE knob is rotated (S205), the microcomputer 120 determines whether the TUNE knob is in a pressed state (S210).

If it is determined that the TUNE knob is in a pressed state, the microcomputer 120 determines whether the TUNE knob has made a left turn or a right turn. If it is determined that the TUNE knob has made a left turn, the CPU 130 searches for the first start song of the previous chorus, and if it is determined that the TUNE knob has made a right turn, the CPU 130 searches for the first chorus of the next chorus S215).

Thereafter, the CPU 130 guides the changed initial sound through the speaker (S220).

Thereafter, the CPU 130 displays the music name searched through the display device on the screen (S225).

Thereafter, when the rotation of the TUNE knob is stopped or the pressed state of the TUNE knob is also released (S230), the CPU 130 informs the music name currently being searched through the speaker and displayed on the screen by voice (S235). The CPU 130 may determine that the rotation of the TUNE knob is stopped when the TUNE knob does not operate again within a predetermined time (for example, 0.5 second) after the TUNE knob operation is stopped.

When the button is clicked without rotation of the TUNE (e.g., after the button is pressed down) (S240), the CPU 130 reproduces the music currently being searched and displayed on the screen (S245).

If it is determined in step S210 that the TUNE knob is not pressed, the microcomputer 120 determines whether the TUNE knob has made a left turn or a right turn. If it is determined that the TUNE knob has made a left turn, the CPU 130 searches for the previous song, and if it is determined that the TUNE knob has made a right turn, the CPU 130 searches for the next song (S250).

Thereafter, the CPU 130 determines whether the beginning of the searched song has been changed (S255).

If it is determined that the beginning of the searched song has not been changed, the CPU 130 performs the process from step S225. On the other hand, if it is determined that the beginning of the searched song has been changed, the CPU 130 performs the process from step S220.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention has been described with reference to Figs. Best Mode for Carrying Out the Invention Hereinafter, preferred forms of the present invention that can be inferred from the above embodiment will be described.

An apparatus for supporting a fast search function of a vehicle AVN system according to a preferred embodiment of the present invention includes a knob rotation sensing unit, an instruction object changing unit, a target information output unit, a power supply unit, and a main control unit.

A device with a high-speed search function can be driven when searching or reproducing a specific object in a vehicle AVN system.

The power supply unit supplies power to each configuration constituting the device supporting the high-speed search function. The main control unit performs a function of controlling the overall operation of each component constituting the high-speed search function supporting device. Considering that the device supporting the high-speed search function is provided in the vehicle AVN system, the power supply unit and the main control unit can be implemented by the vehicle battery and the MCU (or ECU), so that the power supply unit and the main control unit may not be provided in the present embodiment.

The knob rotation sensing unit senses the rotation of the knob mounted on the vehicle AVN system.

When the rotation of the knob is sensed, the instruction target changing unit performs a function of changing an object that is currently indicated and an object whose first character is different from the object to be indicated. In this case, the object to be indicated includes a multimedia file such as a music file or a video file, a broadcast channel such as a track, a radio, or a TV.

The instruction change unit may use a target whose initial character is different from the target whose initial value is different or whose initial spelling is different.

The target information output unit performs a function of outputting information on the changed instruction target.

The apparatus for supporting the high-speed search function may further include a detection time measurement unit and a time difference determination unit.

The sensing time measuring unit measures the sensing time whenever the rotation of the knob is sensed.

The time difference determination unit determines whether the time difference between the current time and the previous time when the rotation of the knob is sensed is greater than or equal to a reference time difference.

When the apparatus for high-speed search function further includes a detection time measuring unit and a time difference determining unit, the object information outputting unit can output information about the object to be indicated when it is determined that the time difference between the current time and the previous time is equal to or greater than the reference time difference .

The high-speed search function supporting apparatus may further include a pressurization state determining unit.

The pressure state determination unit determines whether the knob is rotated in a pressed state when the rotation of the knob is sensed.

When the fast search function supporting device further includes a pressurization state determining unit, the instruction target changing unit changes the object whose first character is different from the first object each time the knob rotation is detected when it is determined that the knob is rotated in the pressed state, If it is determined that the knob is rotated in the unpressurized state, the object positioned in the next order of the object to be currently indicated can be changed to the indicated object each time the rotation of the knob is sensed.

The high-speed search function supporting apparatus may further include a next order object determining unit.

The order-of-arrival determining unit determines whether or not the object positioned in the next order of the target to be currently directed is changed to the indicated target each time the rotation of the knob is detected, As shown in FIG.

When the fast search function supporting device further includes a next order object determining unit, the object information outputting unit may output information about the object positioned in the next order if it is determined that the object positioned in the next order is a different object for the first character.

The fast search function supporting device may further include a target number comparing unit.

The target number comparison unit performs a function of determining whether the number of storage targets is equal to or greater than a reference number when searching a specific target among the storage targets in the vehicle AVN system.

If the fast search function supporting device further includes a target number comparing unit, the indication subject changing unit changes the first character to the indication target each time the rotation of the knob is detected when it is determined that the number of stored objects is equal to or greater than the reference number, If it is determined that the number of objects to be stored is less than the reference number, the object positioned in the next order of the object to be currently indicated can be changed to the object to be indicated each time the rotation of the knob is sensed.

Next, an operation method of the apparatus for supporting the high-speed search function of the vehicle AVN system will be described.

First, the knob rotation sensing unit senses the rotation of the knob mounted on the vehicle AVN system.

Then, when the rotation of the instruction object changeover knob is detected, the object whose current character is different from the current instruction object is changed to the instruction target.

Then, the target information output unit outputs information about the changed target object.

Meanwhile, when the knob rotation sensing unit senses the rotation of the knob, the sensing time can be measured each time the sensing time measuring unit senses the rotation of the knob. This step may be performed simultaneously with the step of sensing the rotation of the knob, but it may also be performed after the step of sensing the rotation of the knob.

After the sensing time measuring unit measures the sensing time, the time difference determining unit determines whether the time difference between the current time and the previous time when the rotation of the knob is sensed is equal to or greater than the reference time difference. This step may be performed before the step of outputting the information on the instruction target in this embodiment.

When it is determined by the time difference determination unit that the time difference between the current time and the previous time is equal to or greater than the reference time difference, the subject information output unit can output information about the current target.

Meanwhile, it is possible to determine whether or not the knob is rotated in the pressed state, when the pressing state determining unit senses the rotation of the knob, simultaneously with the sensing step, or between the sensing step and the changing step.

At this time, if it is determined that the knob is rotated in the pressed state, each time the rotation of the knob is detected, the object with the first character can be changed to the object to be indicated. On the other hand, if it is determined that the knob is rotated in the unpressurized state, the object positioned in the next order of the object to be currently indicated can be changed to the indicated object each time the rotation of the indicated object changeover knob is detected.

On the other hand, between the step of judging whether or not the knob is rotated in the pressed state and the step of outputting, each time the rotation of the knob is detected, , It is possible to judge whether or not the target positioned in the next sequence is the target different from the current target.

In this case, the target information output unit can output information on the target positioned in the next order if it is determined that the target located in the next order is the target of the first character.

On the other hand, before the detecting step, when the target number comparing unit searches for a specific target among the storage targets in the AVN system for the vehicle, it can be determined whether or not the number of target objects is equal to or greater than the reference number.

If it is determined that the number of objects to be stored is equal to or greater than the reference number, the first character is changed to another object each time the rotation of the knob is detected. If it is determined that the number of objects to be stored is less than the reference number, It is possible to change the target positioned in the next order of the current target to the target to be indicated.
