Herein, the microphone 10, the audio / video means 30, the first and second speakers 20, 50, and the cluster 40 are not separately provided devices, but are basically provided in the vehicle. A / V system) and cluster.

The microphone 10 refers to a voice input device provided for a hands-free call for receiving a voice memo of the driver while driving, and the audio / video means 30 selects a recording function and through the microphone 10. When the voice memo is input, the voice memo is stored in the internal memory for recording, the voice memo is played according to a reproduction request, and the voice memo stored in the internal memory is transmitted to the cluster 40.

As shown in FIG. 2, the audio / video means 30 includes an operation unit 31 for setting a recording function, a playback function, an alarm function, and a cluster linkage function, and a real time clock (RTC) generator for providing time information. 32), a control unit 33 for controlling a recording function, a playback function, an alarm function, a cluster interworking function, and a file transfer function in association with the operation unit 31, and a voice for processing the recorded voice input through the microphone 10; The signal processor 34, the voice signal storage unit 35, which stores the voice processed by the voice signal processor 34 in the internal memory 36 as a voice memo, and the internal memory under the control of the controller 33.

(A) When the recording button is turned on while driving, switching to the voice memo mode (S101-S102), (b) After switching to the voice memo mode, if the driver's memo voice is input through the microphone 10, processing the voice signal and storing the voice memo in the internal memory 36 (S103-S105), (c) the internal memory When the voice memo stored in the storage unit 36 is requested, the voice memo stored in the internal memory 36 is reproduced and transmitted through the first speaker 20 (S106 to S107), and (d) the internal memory ( After storing the voice memo in 36), if the alarm function is set, checking the alarm time and automatically reproducing and transmitting the recorded voice memo when the alarm time comes (S108-S110), (e) the internal memory. Voice memos stored in (36) are clustered. When a draw registration request is generated, transmitting the voice memo stored in the internal memory 36 to the cluster 40 in association with the cluster 40 (S111-S112) and (f) the cluster 40. Registering the voice memo as a cluster sound (S113), and (g) reproducing and transmitting the voice memo as a cluster sound according to a reproduction request in the cluster 40 (S114).

In the step (g), when the driver's vehicle ride or welcome condition is reached in the cluster 40, the registered voice memo is reproduced and transmitted as a cluster sound.

The voice memo device and method using the audio / video device of the vehicle according to the present invention configured as described above will be described in detail.

First, when the driver needs to take an urgent note while driving, the driver turns on the recording button provided on the operation unit 31 of the audio / video means 30 without using a mobile device or finding a writing instrument. ) Or the voice memo button provided separately (on) (S101).

When the operation unit 31 or the voice memo button is operated in an on state, the control unit 33 determines by the voice memo function and controls the storage of the voice signal input to the voice signal processing unit 34 (S102). To S105).

For example, if the driver wants to take a memo (voice recording) while driving, the driver speaks a voice for the memo. That is, input a voice for a memo such as "Meeting 00 at 00:00 00 0 0 place" or input a voice memo for use as a cluster sound. Here, the voice memo for using as the cluster sound may be a voice memo such as "Please drive safely."

When the voice is input through the microphone 10, the voice signal processor 34 processes the input voice by a conventional voice processing technique (preprocessing, filtering, amplification, analog / digital conversion, etc.) to generate voice memo data. To the control unit 33.

When the voice memo data is transmitted, the controller 33 generates a voice file by mapping the voice memo data using date / time information obtained by using the real time clock generated by the real time clock generator 32 as a file name.

Subsequently, the controller 33 stores the generated voice file in the internal memory 36 through the voice signal storage 35. Here, the time information obtained through the RTC generator 32 may be used for automatic regeneration when setting the alarm function.

As such, the driver can record a memo by voice while driving safely without using a separate mobile device or taking a memo using a writing instrument while driving.

After recording the voice for memo, the driver requests a playback by operating the playback button provided in the operation unit 31 as necessary (S106). When the reproduction of the voice memo is requested by the operation unit 31, the control unit 33 reproduces the voice memo stored in the internal memory 36, and the reproduced voice memo is processed by the voice signal output unit 36. After it is sent through the first speaker 20. This allows the driver to listen to the voice memo, check the appointment or other memo (S107).

On the other hand, if the alarm function is set (alarm application, date / time, GPS-based, RTC-based) in the situation that the audio / video device is operating, the control unit 33 and the time information generated by the RTC generator 32 automatically; When the alarm is set, the registered alarm time is continuously compared, and when the current time reaches the alarm setting time, a pop-up notifies that the alarm function is activated, and automatically stores the voice memo stored in the internal memory 36. Play it. The voice memo reproduced in this way is transmitted to the first speaker 20 through the voice signal output unit 36 (S108 to S110).

3 is an example of an alarm function, a memo is recorded by the voice recording function, and the voice recording file is reproduced at the driver's request. In addition, the operator sets the alarm of the voice recording file through the alarm function. Alarm setting is made and voice recording file is automatically played when the alarm time comes.

Therefore, the driver can directly find the contents of the memo in the form of recording while driving, and can automatically recognize this through the alarm function without any inconvenience of checking the contents, the appointment time / promise contents, and the like.

In addition, as another feature of the present invention, the voice memo may be utilized as a cluster sound by interworking with the cluster 40.

For example, when the driver requests the driver to register the voice memo as a cluster sound through the key manipulation unit 31 (S111), the controller 33 moves to step S112 and clusters the voice memo stored in the internal memory 36. It transmits to the cluster 40 via the part 38.

The cluster 40 registers the voice memo transmitted in step S113 as a cluster sound.

That is, the voice memo such as "safe driving" is stored as the cluster sound, and the voice memo is registered in the cluster 40 by performing a data interface through the cluster linking unit 38. The voice memo stored in the cluster 40 may be used as a welcome sound. The audio / video means 30 and the cluster 40 may use a cluster audio data transmission interface.

Subsequently, in step S114, the cluster 40 plays back the voice memo as a cluster sound in response to a playback request and transmits the voice memo.

In this case, the cluster sound reproduction request automatically plays the registered voice memo and sends it as a cluster sound when the driver's vehicle is recognized or a welcome condition is reached. The cluster sound output in this way is transmitted through the second speaker 50.

4 illustrates an example of using a voice memo in connection with a cluster.

Voice memo is used to save the voice memo to be used as the cluster sound. When the interlocking function with the cluster sound is executed, the voice memo is generated as the cluster sound interworking file through the voice recording file editing function. Then, the generated cluster sound interworking file (data) is transmitted to the cluster. The cluster registers the transmitted cluster sound interworking data, and when the vehicle is in a vehicle or in a welcome condition, the cluster plays the registered cluster sound interworking file and transmits the registered cluster sound interworking file through the second speaker. Here, the editing function refers to a general audio editing function for generating specific voice memo data as audio sound.

Here, although the present invention has described the cluster sound transmission method between the audio / video means 30 and the cluster 40 as a cluster sound interworking file, the present invention is not limited to this, but the streaming form in the audio / video means 30 is provided. It is also possible to transmit the cluster sound to the cluster 40.

Therefore, the driver can change the sound of the cluster to his or her own preference using only the voice memo function, with or without additional equipment.

Although the invention made by the present inventors has been described in detail according to the above embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit and scope of the present invention. Self-evident to those who have
