Field of the Invention The present invention relates to a vehicle control device and a method thereof, and more particularly, to a vehicle control device and a method including a hands-free device for a vehicle and a voice alarm device, which enable each function of these devices to be controlled as human voice.

In general, one of the most commonly used systems for human driving is the audio system. Recently, as the spread of mobile communication terminals is becoming more common, audio with hands-free function is increasingly used, and a vehicle that outputs a voice message to a driver so that the driver can check the operation state of the vehicle. It is also common to mount alarms. In addition, voice recognition technology can be used to control audio and the like as the driver's voice.

The above audio system, hands-free system, and vehicle alarm system correspond to the optional devices mounted on the vehicle. If these devices are installed separately, the wiring of the car becomes very complicated and each device may collide with each other, resulting in an overall system instability. In addition, when such a device is installed separately, components that are included in duplicate are generated and a problem arises that the overall price is inevitably high.

Accordingly, the present invention is to solve the above problems according to the prior art, an object of the present invention includes a hands-free device, a voice alarm devices in the existing car audio system, and further uses a technology for recognizing the driver's voice It is to provide a control device and a method of a vehicle that allows the user to conveniently use each function.

First, the speech recognition technology, which is one of the technical features of the present invention, will be described.

Voice, text, and sign language exist as a means of communication between people. In particular, the spoken language is one of the means of communication between people who are easy to learn and can be used naturally by almost everyone. Speech recognition, a characteristic technical feature of the present invention, means that a computer understands a person's speech language. Voice recognition technology can be used to access the Internet with a human voice, receive a voice language from a computer, reduce the voice language, understand voice commands, and control a computer or various information devices.

Speech recognition technology is classified into various techniques according to parameters.

Let's look at the techniques of speech recognition according to the voice mode. The technique of recognizing that only one word is spoken is called Isolated Word Recognition, and the technique of recognizing that several words are spoken with a short rest period in the middle is called Connected Word Recognition. Recognizing the pronunciation of several words in succession is called Continuous Speech Recognition. Finally, extracting only a given key word from consecutive speeches is called keyword spotting. In the vehicle audio device according to the present invention, a plurality of words such as "turn on audio" and "turn off audio" are required, so that connection word recognition, continuous speech recognition, key word detection technique, etc., rather than isolated word recognition techniques that recognize only one word It is preferable to use.

In addition, the speech recognition technology is classified according to the speaker dependency as follows. First, Speaker Dependent is a technique for recognizing a specific speaker's voice. The speaker dependent technique requires a process of learning a device that a user inputs and recognizes a voice, and is characterized by using a speech recognition algorithm called Dynamic Time Warping. Second, there is Speaker Independent. Since it recognizes the voice of an arbitrary speaker, the user does not need to learn the recognizer in advance so that the user can conveniently use the voice recognition device. Such a technique is characterized by using algorithms such as Hidden Markov model (HMM) and Neural Network (NN). In the present invention, it is preferable to use the speaker independent method so that not only the motorist but also other occupants of the vehicle can use the car audio device.

Hereinafter, a configuration and operation of a control apparatus for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components even though they are shown in different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a block diagram showing the internal structure of a first embodiment of a speech recognition vehicle control apparatus having an audio system and a hands free system according to the present invention. A configuration of a first embodiment of a voice recognition vehicle control apparatus according to the present invention will be described with reference to FIG. 1.

The first embodiment of the apparatus for controlling a speech recognition vehicle according to the present invention may include a voice input unit 200, an interface unit 400, a voice comparator 300, a controller 100, and an audio system unit 500. .

The voice input unit 200 corresponds to a component that receives a voice command signal for controlling each function of the audio system or the hands free system. Of course, the voice input unit 200 also receives the user's outgoing call voice signal to support the hands-free function for the vehicle.

The voice input unit 200 may generally include a voice recognition microphone 210 and a voice amplifier 220. The voice input unit 200 is connected to the voice comparator 300 and transmits the voice command signal to the voice comparator 300 under the control of the controller 100. In addition, the voice input unit 200 may be connected to the interface unit 400 to transmit the user's outgoing call voice signal to the interface unit 400.

The voice recognition microphone 210 is a component that a user receives a voice command signal for controlling each function of the audio system or the hands-free system or an outgoing call voice signal in a busy state and converts it into an electric voice signal.

The voice recognition microphone 210 is connected to the voice amplifier 220 to transmit a voice command signal or a call voice signal to the voice amplifier 220.

The voice amplifier 220 amplifies the user's voice signal received by the voice recognition microphone 210. That is, the voice amplifier 220 is in charge of an amplification process for improving the signal-to-noise ratio of the input voice signal to a degree suitable for signal processing.

The voice amplifier 220 is connected to the voice comparator 300 and the interface 400. The transmitted voice command signal is transmitted to the voice comparator 300. On the other hand, the user's outgoing call voice signal is transmitted to the mobile communication terminal through the interface unit 400. The control unit 100 is responsible for the control of the voice signal transmission process.

The interface unit 400 is a component that serves as an exchange passage of an outgoing or incoming call voice signal between the mobile communication terminal and the vehicle control apparatus according to the present invention.

The interface unit 400 is connected to the earphone terminal of the external mobile communication terminal. Of course, the interface unit 400 may be configured to be connected to the 24-pin connection terminal of the external mobile communication terminal. In addition, the interface unit 400 according to the present invention is connected to the voice input unit 200 and the speaker unit 510 in the vehicle control apparatus.

Let us look at the process of transmission of the outgoing or incoming call voice signal according to the connection of the interface unit 400. The call voice signal of the third party received by the mobile communication terminal is output to the interface unit 400, which is transmitted to the speaker unit 510 of the vehicle control apparatus. Conversely, the user's outgoing call voice signal received by the voice input unit 200 is transmitted to the mobile communication terminal through the interface unit 400. Of course, the control of the call voice signal flow is the control unit 100.

A general hands-free system for automobiles is composed of an interface unit interconnected with a connection terminal of a mobile communication terminal, a voice recognition microphone for converting a user's voice signal into an electric voice signal, and a speaker for outputting voice received through a mobile phone. . In the vehicle control apparatus according to the present invention, the voice recognition microphone and the speaker are components commonly used for the car audio function and the voice recognition function as well as the hands-free function. In the present invention, there is an advantage that only the interface unit 400 is required to use the hands-free function.

The voice comparator 300 is a device that determines what command the user has made when the user commands the car audio system and the hands-free system by voice. In detail, the voice comparator 300 compares whether the voice command signal received from the voice input unit 200 matches voice data stored in the memory 310. At this time, the voice comparator 300 compares the voice command signal and the voice data by using the continuous voice recognition technique and the speaker independent voice recognition technique using a speech recognition algorithm such as HMM and NN among the speech recognition techniques described above. Can be.

The voice comparator 300 reports the result of the voice command signal and the voice data to the controller 100 when there is voice data matching the voice command signal. If the same voice data as the voice command signal cannot be retrieved, an error signal is transmitted to the controller 100.

Voice data for operating the audio system or the hands-free system are stored in the memory unit 310. The memory unit 310 is a storage device that stores voice data to be compared with a voice command signal of a user.

The memory unit 310 is connected to the voice comparator 300 to transmit voice data to be compared with the voice command signal. The memory unit 310 may be embedded in the voice comparator 300 or the controller 100 or may exist as an independent component. Since the user may add, change, or delete voice data stored in the memory unit 310, the user may adjust a service provided by the vehicle control apparatus according to the present invention to the user.

The controller 100 is a device that is in charge of the overall control of the vehicle control apparatus according to the present invention. Let us look at the characteristic control function of the control unit 100 of the vehicle control apparatus according to the present invention.

First, when the voice comparator 300 compares the voice command signal with the voice data, if there is voice data matching the voice command signal of the user, the voice comparator 300 transmits the result to the controller 100. At this time, the control unit 100 controls the corresponding function of the car audio system or the hands-free system according to the result.

For example, when a user commands an "audio volume up", the voice input unit 200 receives a user's voice command and transmits the voice command to the voice comparator 300. The voice comparator 300 retrieves voice data matching the received “audio volume up” voice signal and reports the result to the controller 100. The control unit 100 controls the audio system (control to increase the volume of the audio by one level) corresponding to the result. In addition, when a command of "call number 1" is made in relation to the hands-free function, the control unit 100 may control the hands-free system for calling the phone number stored in the speed dial number 1 through the same process.

Secondly, when the voice recognition function is activated, the controller 100 may control to automatically deactivate the voice recognition function when an error having no voice data matching the input voice command signal occurs several times or more. When the voice command signal is input, the voice comparator 300 may fail to search voice data matching the voice command signal. As described above, when such a phenomenon occurs, the voice comparator 300 transmits an error signal to the controller 100. The controller 100 memorizes the number of error signals transmitted from the voice comparator 300 and automatically stops the operation of the voice comparator when an error occurs several times. Through this process, the controller 100 automatically controls to stop the voice recognition function.

Third, the controller 100 controls the flow of the voice signal when the user makes a call using the hands-free function. When a user makes a call using the invention according to the present embodiment, there may be an incoming call voice signal from a third party who is the user's conversation partner, an outgoing call voice signal of the user, and an acoustic signal generated from the audio. Appropriate control of the flow of the voice or sound signal allows the user to properly use the automotive audio system and the hands free system.

The controller 100 controls the speaker unit 510 to transmit only an incoming call voice signal from a third party among these three signals. Conversely, the control unit 100 controls to transmit only the outgoing call voice signal of the user received by the voice recognition microphone to the mobile communication terminal only through the interface unit 400. Lastly, the controller 100 controls the audio system to mute the audio system when the user is in a call and outputs only the incoming call voice signal to the speaker unit 510.

Finally, the controller 100 may control whether the hands-free function and the voice recognition function are driven. The user does not always need hands-free and voice recognition. In contrast, the vehicle control apparatus according to the present invention enables the user to activate only a desired function. For example, the user may stop the operation of the hands-free function through manipulation of the key button input unit 520 of the audio system unit 500. When the user manipulates the key button input unit 520, the key button input unit 520 transmits a control signal corresponding to the user's operation to the control unit 100, and the control unit 100 controls accordingly.

In this case, the controller 100 may control to activate the hands-free function and the voice recognition function when the car key exists in the ACC.IGN position even if the vehicle is not started.

The audio system unit 500 included in the first embodiment of the vehicle control apparatus according to the present invention will be described.

The audio system unit 500 has a configuration similar to that of a general automotive audio system. First, the audio system unit 500 may include a radio tuner 540, a tape player 550, a CD player 560, a key button input unit 520, a speaker unit 510, a display unit 530, and the like. have. Among them, the radio tuner 540, the tape player 550, and the CD player 560 have the same functions as the existing car audio and thus will not be described.

The speaker unit 510 included in the audio system unit 500 serves to generate a voice signal that can be heard by the user. However, unlike the existing car audio system, the speaker unit 510 of the present invention has a function of outputting not only an acoustic signal transmitted from a radio tuner 540, a tape player 550, a CD player, but also a voice signal of a call. Will also do.

The speaker unit 510 is directly and indirectly connected to the radio tuner 540, the tape player 550, and the CD player 560, and outputs sound signals generated from these components. In addition, the speaker unit 510 of the audio system unit 500 is also connected to the interface unit 400. Accordingly, the user can hear the incoming call voice signal from the third party through the speaker unit 510.

The key button input unit 520 of the audio system unit 500 corresponds to a component in which a user manually operates the audio system. In the present invention, the user can perform operations related to the hands-free system and the voice recognition function as well as the operation of the audio system using the key button input unit 520.

In the present invention, the display unit 530 of the audio system unit 500 is not only audio-related information such as volume, equalizer, radio channel frequency, but also information related to voice recognition function, hands-free function related information such as call time and caller indication. Can guide you visually.

2 is a block diagram showing the internal structure of a second embodiment of a speech recognition vehicle control apparatus having an audio system and a hands free system according to the present invention. The configuration of a second embodiment of a voice recognition vehicle control apparatus according to the present invention will be described with reference to FIG. 2.

The control device of the second embodiment adds a voice vehicle alarm function for guiding the state of the vehicle by voice to the first embodiment. The second embodiment of the speech recognition vehicle control apparatus according to the present invention is the voice input unit 200, the interface unit 400, the voice comparator 300, the control unit 100, the audio system unit 500 and the car check unit ( 600).

Since the functions of the voice input unit 200, the interface unit 400, the voice comparator 300, and the audio system unit 500 are the same as those of the first exemplary embodiment according to the present invention, a detailed description thereof will be omitted.

The vehicle check unit 600 is a component that checks the abnormality of various devices of the vehicle. As an abnormality of various devices of the vehicle, there may be a shock state of the vehicle due to the speed, theft, etc. of the vehicle while driving, a defect state of a component such as an engine of the vehicle, and the like.

The vehicle checking unit 600 is connected to the control unit 100 and transmits a check result of various devices of the vehicle.

For example, the car checking unit 600 continuously checks whether the speed limit is exceeded using the navigation function, whether a big shock is applied to the car, and the like. The vehicle checking unit 600 transmits a test result signal for the current state of the vehicle to the controller 100.

The controller 100 basically includes the functions of the controller 100 of the first embodiment according to the present invention. In addition, the control unit 100 according to the second embodiment controls the speaker unit 510 according to a check result signal for the presence or absence of various devices of the vehicle transmitted from the vehicle checking unit 600.

 For example, when a vehicle defect such as an engine of a vehicle is detected, the speaker unit 510 may control to send a message indicating that “the engine of the vehicle has an abnormality”, and the impact of the vehicle due to theft may be detected. If so, it may cause the speaker unit 510 to sound an alarm.

In addition, the controller 100 may control to activate the hands-free function, the voice recognition function, and the voice alarm function when the car key exists in the ACC.IGN position even when the vehicle is not started.

In particular, in relation to the voice alarm function, the controller 100 may instruct the vehicle check unit 600 to check a vehicle body shock due to theft even when the vehicle is completely turned off. When the vehicle is started or the car key is turned to the ACC.IGN position, the control unit 100 immediately controls to report to the user whether there is a problem with the vehicle while the engine is turned off.

The operation according to the second embodiment of the vehicle control apparatus according to the present invention including such components will be described. Since the operation of the first embodiment is included in the second embodiment, description thereof is omitted.

When the vehicle is powered on, the user may select which of the hands-free function, the voice alarm function, and the voice recognition function to be operated by using the key button input unit 520.

Basically, when the vehicle is started, the vehicle control apparatus according to the present invention is driven. Of course, as described above, when the key position of the vehicle is in ACC.IGN, the user can manually drive the vehicle control apparatus. At this time, the user can select which function to use.

The hands-free function may be activated by the user by operating the key button input unit 520, or the hands-free function may be automatically activated when an incoming call is received by the mobile communication terminal connected to the vehicle control device. In addition, the user may similarly drive the key button input unit 520 with a voice recognition function or a voice alarm function.

When the user activates the hands-free function, let's look at the operation process of the vehicle control apparatus according to the present invention.

In order to perform the hands-free function, the incoming call voice signal should be output to the speaker unit 510 so that the user can hear it, and the outgoing call voice signal should be transmitted to the mobile communication terminal. Let's take a look at this transfer process.

Let us look at the operation of the vehicle control device when receiving a third party voice call signal. The call voice signal of the third party is transmitted to the speaker unit 510 through the interface unit 400. At this time, the controller 100 determines whether the car audio system is currently in a call and performs control of transmitting only the voice signal of the third party received by the interface unit 400 to the speaker unit 510.

An operation in the case of sending a call voice signal of the user will be described. When the user pronounces the call voice, the voice recognition microphone receives the call voice signal and transmits it to the interface unit 400. At this time, the control unit 100 determines whether a call is currently made through the mobile communication terminal 410, and controls to transmit only the call voice signal to the interface unit 400.

Through this process, the user can use the hands-free function according to the embodiment of the present invention.

Let's take a look at the operation of the speech recognition function.

When the voice recognition mode of the car audio system is activated and the user commands the voice, the voice recognition microphone 210 of the voice input unit 200 receives the voice command signal of the user and transmits the voice command signal to the voice comparator 300. In this case, an amplification process of the speech signal may be added to increase the speech recognition accuracy. The voice amplification unit 220 included in the voice input unit 200 is in charge of amplifying the voice signal.

The voice comparator 300 determines whether the voice command signal received from the voice input unit 200 matches voice data for operating the audio system or the hands free system, and transmits the comparison result to the controller 100. In detail, when there is voice data matching the voice command signal, the voice comparator 300 transmits information corresponding to the voice command signal to the controller 100. On the other hand, when there is no voice data matching the voice command signal, the voice comparator 300 transmits an error signal to the controller 100.

If the controller 100 receives information corresponding to the voice data matching the driver's voice command signal, the controller 100 drives a corresponding function of the audio system or the hands free system according to the information. If an error signal is transmitted from the voice comparator 300, the controller 100 stores the number of consecutive occurrences of the error signal. The controller 100 stops the operation of the voice input unit 200 when the generation of the error control signal is repeated a predetermined number of times. If the input of the error control signal is repeated less than a predetermined number of times, the controller 100 prepares to receive a user's voice command again. Through this process, the controller 100 may control to automatically stop the voice recognition function in the car audio system.

Let's look at the operation of the voice alarm function of the vehicle control unit.

When the user activates the function of the voice alarm device, the vehicle checking unit 600 continuously checks the state of various devices of the vehicle. In addition, the vehicle checking unit 600 continuously reports the result of the abnormality check to the controller 100.

The control unit 100 receives check results for various devices of the vehicle and analyzes the result and transmits a message to the speaker unit 510. The error message is output as a voice signal from the speaker unit 510 included in the audio system unit 500.

A first control method of a vehicle having an audio system and a hands-free system according to the present invention corresponding to such a vehicle control apparatus will be described step by step with reference to FIG. 3. 3 is a flowchart illustrating the operation of the vehicle control method according to the present invention.

As shown in Figure 3, the vehicle control device is a vehicle driven or ACC. If a car key is present in the IGN position, it is driven by the user's manual operation. In this case, the vehicle control apparatus according to the present invention may allow the user to select which function is activated. The user can select whether to activate each of the hands free function and the voice recognition function. (S100)

The control method of the vehicle control apparatus according to the present invention will be described with respect to the hands-free function.

The user may manually activate the hands-free function and automatically activate the hands-free function when an incoming call is received by the mobile terminal connected to the vehicle control device (S1100).

When the hands-free function is activated, a control method when a third party call voice signal is received by the mobile communication terminal will be described. The vehicle control apparatus outputs the call voice signal only through the speaker unit to the incoming call voice signal of the third party received by the mobile communication terminal. (S1110)

When the hands-free function is activated, a control method for transmitting a call voice signal of a user through a mobile communication terminal will be described. First, the vehicle control apparatus receives a user's outgoing call voice signal. The vehicle controller transmits only the outgoing voice call signal pronounced by the user to the mobile communication terminal. (S1120)

In the first control method of a vehicle having an audio system and a hands-free system, a method of controlling a speech recognition function will be described.

The user may activate the hands-free function by using a key button input of the audio system. (S1200)

The vehicle control device receives a voice command signal of a user for controlling each function of the audio system or the hands free system. If the voice command signal is not received, the vehicle control apparatus continues the process of waiting for the user's voice command signal. (S1210)

In this process, the vehicle control apparatus may amplify the voice command signal to increase the voice recognition accuracy. (S1220)

The vehicle controller compares the voice command signal with voice data for driving an audio system or a hands free system. (S1230)

If there is voice data matching the voice command signal, the vehicle controller controls a corresponding function of the audio system or the hands-free system according to the comparison result. (S1240)

If the same voice data as the voice command signal does not exist in step S1230, the vehicle controller generates an error signal. (S1250)

If the error signal is generated more than a predetermined number of times, the vehicle controller automatically stops the voice recognition function, and if an error less than the set number of times occurs, the vehicle control apparatus automatically returns to the previous step of S1210 waiting for the user's voice command. (S1260)

Through such a control method, an audio system and a hands-free system in the vehicle can be controlled using voice recognition technology.

A second embodiment of a method for controlling a vehicle having an audio system and a hands free unit according to the present invention will be described step by step with reference to FIG. 4. 4 is a flowchart illustrating an operation of a vehicle control method according to a second embodiment of the present invention. The control method of the second embodiment adds a voice vehicle alarm control method to the control method according to the first embodiment.

As shown in FIG. 4, the vehicle control apparatus basically starts control with the driving of the vehicle. In this case, the vehicle controller may allow the user to select which function is activated. In the vehicle control method according to the second embodiment, the user may select whether the hands-free function, the voice alarm function, and the voice recognition function are activated. (S2000)

The hands-free function and the voice recognition function have already been described, so let's take a look at the control method when the user activates the voice alarm function. (S2300)

The vehicle control apparatus checks whether there is an abnormality according to the driving state of the various devices of the vehicle. (S2310)

The vehicle control apparatus outputs a guide voice message to the speaker according to the check result of the various devices of the vehicle. (S2320)

Through such a control method, not only the audio system and the hands-free system in the vehicle can be controlled using voice recognition technology, but also the voice alarm function can be controlled.

The vehicle control apparatus and control method according to the present invention as described above can optimize the vehicle by integrating the hands-free, voice alarm, and voice recognition functions in addition to the existing audio functions.

Conventionally, in order to implement a function of hands-free, voice alarm, and voice recognition in a vehicle, there has been inconvenience of having to purchase and install each module separately. When implementing a function using each module as described above, a problem arises that it is expensive. Wiring becomes complicated because overlapping components common to use the three functions are overlapped. In addition, since there must be a plurality of control units for controlling each function, a case in which each function collides frequently occurs frequently, which inconveniences the user.

When implementing the vehicle control apparatus and the control method according to the present invention, since only one device is required to implement the first, hands-free, voice alarm, and voice recognition function, the cost can be saved. Secondly, in the case of configuring only one component, such as the control device according to the present invention, since there are no overlapping components, wiring can be efficiently performed. Finally, since only one control unit is required to control each function, the risk of collision can be greatly reduced in operating each function.
