Description

{VEHICLE AND VOICE COMMAND CONTROL METHOD OF VEHICLE}

The present invention relates to a vehicle, and more particularly to voice command control of a vehicle.

When a driver wants to use various functions of a vehicle, he or she basically operates physical buttons or a touch screen. Recently, with the advancement of voice recognition technology, it has become possible to perform the desired function through voice commands instead of directly operating physical buttons or a touch screen.

However, for some voice commands, the intended function is not performed immediately with a single utterance, but requires the driver's intervention in several steps. In such cases, the driver may not be able to fully concentrate on driving because he or she must perform a reaction related to the voice command until the voice command is finally executed.

According to one aspect of the present invention, the purpose is to minimize the intervention of a user (driver) when performing a voice command and to enable faster control based on a voice command.

The voice command control method of a vehicle according to the present invention for the above-described purpose comprises the steps of: receiving a quick execution voice command in a pre-arranged format; displaying a recommendation result related to the quick execution voice command on a display in response to receiving the quick execution voice command; and executing a control corresponding to the quick execution voice command based on the recommendation result after a preset time has elapsed after the display of the recommendation result.

In the voice command control method of the vehicle described above, the quick execution voice command in the pre-arranged format is in a form in which a pre-arranged prefix or suffix is added to mean the quick execution voice command.

In the voice command control method of the vehicle described above, the recommendation result related to the quick execution voice command includes a first recommendation result and a second recommendation result; the first recommendation result is executed without the user's selection after the preset time has elapsed, and the second recommendation result is executed by the user's selection within the preset time.

FIG. 1 is a drawing showing the exterior of a vehicle according to an embodiment of the present invention. An antenna (152) for receiving broadcast signals and communication signals is installed on the exterior of the vehicle (100). The broadcast signals may include radio signals and DMB (Digital Multimedia Broadcasting) signals. The communication signals may include call signals through mobile devices, GPS (Global Positioning System) signals, and telematics signals. The broadcast signals and communication signals received through the antenna (152) are transmitted to the AVN (see 200 of FIG. 2) provided inside the vehicle (100).

FIG. 2 is a drawing showing the interior of the vehicle shown in FIG. 1. As shown in FIG. 2, an AVN (200) and a steering wheel (202) are mounted on the front of the driver's seat. The AVN (200) is an integrated audio/video/navigation system and includes a display (214). The AVN (200) is based on voice recognition control. To this end, a voice recognition button (204) is mounted on the steering wheel (202). In addition, a microphone (206) is mounted on the upper part of the driver's seat. A speaker (216) is mounted on the left door of the driver's seat and the right door of the passenger's seat. The AVN (200) of the vehicle (100) according to an embodiment of the present invention is based on voice recognition control, and the voice recognition button (204), microphone (206), speaker (216), etc. can be used as auxiliary tools for voice recognition control of the AVN (200).

Figure 3 is a drawing showing the configuration of the AVN shown in Figure 2.

The AVN (200) shown in Fig. 3 is based on voice recognition control. As shown in Fig. 3, the configuration of the AVN (200) can be largely divided into elements for voice recognition function, elements for general input function, elements for broadcasting/communication function, elements for navigation function, elements for audio/video function, and elements that can be commonly used for multiple functions.

The components for the voice recognition function include a voice recognition button (204), a microphone (206), a voice recognition processing unit (308), and a command output interface (318). The components for the broadcast/communication function include an antenna (152), a tuner unit (354), a broadcast signal processing unit (356), and a communication signal processing unit (358). The components for the navigation function include a navigation database (362) and a navigation driving unit (364). The components for the audio/video function include an audio/video input unit (372) and an audio/video playback unit (374). The components for the general input function include an input unit (382). The components that can be commonly used for multiple functions include a memory (310), a control unit (312), a display (214), and a speaker (216). This functional division is not limited to what is described above, and an element for one function may be used for another function.

The voice recognition button (204) allows a user (e.g., a driver) to execute and use composite functions such as audio functions, video functions, navigation functions, and information and communication functions of the AVN (200). To this end, the voice recognition button (204) supports one-key operation in the Push-To-Talk (PTT) manner. The voice recognition button (204) can be installed on the steering wheel (202) so that the user can conveniently operate it while driving. The steering wheel (202) is a steering device used to change the direction of travel of the vehicle (100) by moving the wheels of the vehicle (100) left and right. Since the user always holds the steering wheel (202) while driving, if the voice recognition button (204) is installed on the steering wheel (202), the user can conveniently operate the voice recognition button (204) while driving. In addition to the steering wheel (202), the voice recognition button (204) may be installed anywhere in the vehicle (100) so that the user can easily operate the voice recognition button (204) while driving.

The microphone (206) receives a voice signal spoken by the user while the voice recognition control function is running and converts the received voice signal into an electric signal. The microphone (206) may be a microphone provided for voice recognition control or may be a microphone shared with a hands-free microphone of the vehicle (100). In addition, the microphone (206) may be a microphone of a mobile terminal carried by the user. When using the microphone of the mobile terminal, the mobile terminal and the AVN (200) must be connected to each other through short-range communication such as Bluetooth.

The voice recognition processing unit (308) performs voice recognition on the electric signal converted by the microphone (206) and extracts voice command information as a result of the voice recognition. The voice command information extracted by the voice recognition processing unit (308) is transmitted to the control unit (312).

The command output interface (318) is for transmitting a signal of a control command corresponding to voice command information extracted as a result of voice recognition from the control unit (312) to the controlled target device.

The antenna (152) is a device for receiving radio waves in the air or sending radio waves into the air for the purpose of receiving broadcast signals or transmitting and receiving communication signals. The antenna (152) is communicatively connected to the tuner unit (354). Accordingly, radio waves received by the antenna (152) are transmitted to the tuner unit (354). The antenna (152) may be configured with multiple types of antennas for multiple different types of broadcast/communication signals.

The tuner unit (354) receives the radio waves received by the antenna (152) and converts them into intermediate frequency signals, etc. In addition, the tuner unit (354) converts the data signals to be transmitted into a form that can be transmitted into the air and sends them into the air through the antenna (152). In other words, the tuner unit (354) performs tasks such as extracting only signals of a specific band or combining data signals with carrier signals. The tuner unit (354) performs reception of broadcast signals and transmission and reception of communication signals. The broadcast signals may include radio broadcast signals and DMB (Digital Multimedia Broadcasting) broadcast signals. The communication signals may include satellite communication signals with Global Positioning System satellites (hereinafter referred to as GPS satellites). In addition, the communication signals may include communication signals for telematics. The signal to be received and processed in the tuner unit (354) is determined by the control signal transmitted from the control unit (312) to the tuner unit (354). For example, if the control unit (312) generates a control signal to the tuner unit (354) to receive a radio broadcast signal of a specific channel, the tuner unit (354) receives the radio broadcast signal of the corresponding channel in response to the control signal transmitted from the control unit (312). If the control unit (312) transmits a control signal and transmission data for transmitting a telematics signal to the tuner unit (354), the tuner unit (354) converts the transmission data into a form that can be transmitted into the air in response to the control signal transmitted from the control unit (312) and transmits the converted signal into the air through the antenna (152). In addition, the tuner unit (354) obtains information on the broadcast channel included in the broadcast signal. The broadcast signal input to the tuner unit (354) includes the name of the broadcast channel, service ID, and broadcast data. The tuner unit (354) extracts the name of the broadcast channel, service ID, and broadcast data included in the broadcast signal and transmits them to the broadcast signal processing unit (356) and the control unit (312) at the rear.

The broadcast signal processing unit (356) performs a series of signal processing by dividing the broadcast signal that has passed through the tuner unit (354) into a video broadcast signal and an audio broadcast signal. The series of signal processing performed in the broadcast signal processing unit (356) may include analog-to-digital conversion, digital-to-analog conversion, converting video data into a signal that can drive the display (214), etc.

The communication signal processing unit (358) processes communication signals with GPS satellites and telematics communication signals. That is, the communication signal processing unit (358) converts a received communication signal into a data form for transmission to the control unit (312), or receives data to be transmitted through the tuner unit (354) and antenna (152) from the control unit (312) and converts it into a signal in a communicable form.

The navigation database (362) includes data for implementing navigation. The navigation database (362) may be in the form of a memory card or a DVD (Digital Versatile Disc). In addition, navigation data provided from a mobile terminal connected via a wired/wireless link (e.g., CarPlay or Android Auto) may be utilized as the navigation database.

The navigation driving unit (364) configures a navigation screen on the display (214) using data provided from the navigation database (362). To this end, navigation setting information such as a destination, waypoint, and route type set by the user is provided from the control unit (312). In addition, to implement navigation, the current location information of the vehicle (100) obtained through communication with a GPS satellite is provided from the control unit (312).

The audio/video input unit (372) may be an optical disc drive. Alternatively, the audio/video input unit (372) may be a universal serial bus (USB) input/output device or an auxiliary input/output terminal (also known as AUX). Alternatively, the audio/video input unit (372) may be a Bluetooth device for wireless connection with a mobile terminal. The mobile terminal connected to the audio/video input unit (372) via Bluetooth may be a mobile phone or a portable digital audio playback device.

The audio/video playback unit (374) enables audio/video data input through the audio/video input unit (372) to be output to the speaker (216) or the display (214). For example, when the audio/video input unit (372) is an optical disc drive, the optical disc drive reads audio/video data recorded on an optical disc (CD/DVD/BD, etc.) and outputs the audio/video data, and the audio/video playback unit (374) converts the audio/video data output by the audio/video input unit (372) into a signal capable of driving the speaker (216) or the display (214) and transmits the signal to the speaker (216) or the display (214), thereby enabling the audio/video to be played. In the case of audio/video data provided from a medium other than an optical disc, the data may be converted into a signal capable of driving the speaker (216) or the display (214) while passing through the audio/video playback unit (374).

The input unit (382) may be at least one button provided on the AVN (300) or a touch screen implemented on the display (214). The user may select one of the composite functions of the AVN (300) by operating the input unit (382) and may make various settings so that the expected operation can be performed from the selected function. The voice recognition button (104) of the steering wheel (102) described above may also be included in at least one button constituting the input unit (382).

The control unit (312) is involved in the overall operation of the AVN (200) and performs necessary control. For example, in response to the operation of the voice recognition button (104), it drives an application related to the voice recognition function of the memory (310) so that the initial entry screen is displayed and a related voice guidance message is output. In addition, the control unit (312) receives voice command information provided from the voice recognition processing unit (308) and generates a control command corresponding to the corresponding voice command information so that control corresponding to the voice command information is performed. In addition, the control unit (312) can perform processing of broadcasting/communication signals. If audio/video data generated after processing of the broadcasting/communication signal is to be output to the speaker (216) or the display (214), it controls the corresponding audio/video data to be transmitted to the speaker (216) or the display (214), thereby enabling the output of necessary audio/video data. In addition, the control unit (312) controls the navigation database (362), the navigation driving unit (364), the display (214), and the speaker (216) when the user selects the navigation function so that the navigation can be implemented. In addition, the control unit (312) controls the audio/video data input through the audio/video input unit (372) to be played by the audio/video playback unit (374) and transmitted to the speaker (216) or the display (214), thereby enabling the output of the necessary audio/video data. In addition, the control unit (312) converts the name of the broadcast channel extracted from the broadcast signal by the tuner unit (354) into text and transmits it to the voice recognition processing unit (308).

The memory (310) stores various applications that are executed to perform each of the voice recognition function, broadcasting/communication function, navigation function, and audio/video function of the AVN (200), as well as screen display data, voice data, and sound effect data required for execution of the applications.

The display (214) outputs a video accompanying the performance of the voice recognition function, broadcasting/communication function, navigation function, audio/video function, and other composite functions of the AVN (200). For example, guidance screens, messages, video data, etc. for each function are output through the display (214).

The speaker (216) outputs audio accompanying the performance of composite functions such as voice recognition function, broadcasting/communication function, navigation function, and audio/video function of AVN (200). For example, guidance messages, sound effects, and audio data for each function are output through the speaker (216).

FIG. 4 is a drawing showing a method for performing a voice command of a vehicle according to an embodiment of the present invention.

In the description of the embodiment of the present invention, two terms, 'general voice command' and 'quick execution voice command', are used. Both the general voice command and the quick execution voice command are voice commands generated by the driver's utterance. Among these, the general voice command is a voice command in which the driver and the AVN (200) undergo several stages of two-way interaction (for example, the driver's option selection in several stages) between the driver's utterance and the actual control, and then the control corresponding to the voice command is finally performed. In contrast, the quick execution voice command is a voice command in which the stages of two-way interaction between the driver and the AVN (200) are minimized from the driver's utterance to the actual execution. In addition, the quick execution voice command may be a form in which, in addition to the form in which the stages of two-way interaction are reduced, the driver's intervention is relatively minimized compared to the general voice command, and the proportion of the preset automatic execution process may be greater than that of the general voice command.

For example, when opening a window of a vehicle (100), the driver must go through a number of selection processes, such as selecting the window to be opened and the degree of opening, before the window opening control is performed. A general voice command is performed through all of these preset processes to perform the final control, and can be registered in the form of 'window opening' or 'window opening'. In contrast, a quick execution voice command is performed through only some of the preset processes mentioned above to perform the final control, and can be registered in the form of 'quick window opening' or 'quick window opening'. In this form of quick execution voice command, 'quick' is a prefix assigned to distinguish a quick execution voice command from a general voice command. That is, a quick execution voice command can be created by adding a pre-arranged prefix to the very front of a general voice command. In an embodiment of the present invention, the prefix assigned to a quick execution voice command is not limited to 'quick', and various other prefixes may be used to indicate a quick execution voice command. For example, other prefixes that could be used to indicate a quick-action voice command could include words like 'immediate', 'express', 'quick', 'one-shot', and 'speed'. Also, a more specific prefix like 'quick-action' could be used instead of 'quick'.

You can also use suffixes instead of prefixes to distinguish quick-action voice commands. For example, you can add a suffix to the end of a regular voice command to distinguish it from a quick-action voice command, indicating that it is a quick-action voice command. For example, the regular voice command 'open window' or 'open window' can be expressed as a quick-action voice command such as 'open window quickly' or 'open window quickly'.

FIG. 4 illustrates how a general voice command and a quick execution voice command are generated and executed, respectively, in a method for executing a voice command of a vehicle according to an embodiment of the present invention.

As shown in Fig. 4, in response to the driver operating the voice recognition button (204) of the vehicle (100), the control unit (312) activates the voice recognition mode of the vehicle (100) (402). As the voice recognition mode is activated, an environment is created in which the vehicle (100) can receive a voice signal, analyze it, and recognize a voice command.

When a voice signal is received through the microphone (206) while the voice recognition mode is activated, the control unit (312) analyzes the voice signal and recognizes the voice command (404).

When a voice command occurs in this way, the control unit (312) checks whether the voice command is a quick execution voice command or a general voice command (406). The definition and distinction between quick execution voice commands and general voice commands have already been explained above.

If the currently occurring voice command is a general voice command ('No' of 406), the control unit (312) ensures that a predetermined control is performed through a preset process of the voice command (408). That is, when performing a voice command, the control unit (312) ensures that the final control corresponding to the voice command is performed by completely going through all preset processes without reducing or omitting the voice command execution process.

If the currently occurring voice command is a quick execution voice command ('Yes' of 406), the control unit (312) displays the system recommendation result on the display (214) of the AVN (200) as the first step in executing the quick execution voice command (410). The system recommendation result is a result recommended by the AVN (200) to execute the quick execution voice command, and may include a first recommendation result and a second recommendation result. Such a system recommendation result is explained as follows through Fig. 5.

FIG. 5 is a diagram showing the display of the system recommendation result in the vehicle voice command execution method according to an embodiment of the present invention. As shown in FIG. 5, the display (214) is provided with a system recommendation result display area divided into a first recommendation result display area (502) and a second recommendation result display area (504). The first recommendation result display area (502) displays the first recommendation result among the system recommendation results. The second recommendation result display area (504) displays the second recommendation result among the system recommendation results. The first recommendation result is the target that best matches the preset criteria (or has the highest priority) among the targets of the currently generated quick execution voice command. The second recommendation result is the target of the currently generated quick execution voice command, excluding the target of the first recommendation result, displayed in the order of matching the preset criteria (or in the order of high priority). The second recommendation result may be a single or a plurality of second recommendation results. The first recommendation result is executed automatically after a preset time has elapsed without a separate selection process by the driver, whereas the second recommendation result is executed only after a separate selection by the driver.

In FIG. 5, the first recommendation result display area (502) is formed on the right side of the display (214), and the second recommendation result display area (504) is formed on the left side of the display (214). In this case, the vehicle (100) is a so-called 'left-hand drive vehicle' in which the driver's seat is located on the left side, as shown in FIG. 2. In the case of a left-hand drive vehicle, the display (214) is generally located on the right side of the driver. This arrangement is intended to enable the driver located on the left side of the display (214) to more easily select the second recommendation result located on the left side of the display (214) (i.e., closer to the driver) using his right hand. If the vehicle (100) is a so-called 'right-hand drive vehicle' in which the driver's seat is located on the right side, the first recommendation result display area (502) may be formed on the left side of the display (214) and the second recommendation result display area (504) may be formed on the right side of the display (214) so that the driver in the driver's seat can select the second recommendation result with his or her left hand.

Returning to Fig. 4, when a preset time has elapsed from the time when the quick execution voice command is generated ('Yes' of 412), the control unit (312) performs the quick execution voice command (416) by reflecting the first recommendation result displayed in the first recommendation result display area (502) even if there is no driver selection. Here, the preset time may be, for example, 5 seconds.

Conversely, if the user (driver) selects one of the second recommendation results ('Yes' at 424) before the preset time elapses ('No' at 412), the control unit (312) performs a quick execution voice command (426) reflecting the user's selection. The user can select one of the second recommendation results to be performed when the first recommendation result is not what he or she wants.

The control unit (312) waits for a preset time to receive the user's selection, and if the user does not select one of the second recommendation results after the preset time has elapsed ('No' of 424), it performs a quick execution voice command (416) by reflecting the first recommendation result displayed in the first recommendation result display area (502) as described above.

FIGS. 6 to 11 are drawings showing examples of displaying system recommendation results when a voice command is performed by a vehicle according to an embodiment of the present invention.

First, Fig. 6 is a drawing showing a first example of displaying a system recommendation result when a voice command is performed by a vehicle according to an embodiment of the present invention. The example shown in Fig. 6 is a case where a driver utters “Guide me to a gas station near Yangjae Station ‘quickly’” to generate a voice command for guidance to a gas station. Here, ‘quickly’ is a prefix indicating a quick execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays the recommended results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), as shown in FIG. 6.

The first recommendation result display area (502) of Fig. 6 displays information on the most recently visited gas station. Since many drivers tend to choose a specific gas station and use it frequently, there is a high probability that they will use the most recently (immediately before) used gas station again in the future. Therefore, the first recommendation result display area (502) displays information on the most recently visited gas station.

The second recommendation result display area (504) of Fig. 6 displays information on gas stations with higher priority based on criteria different from those displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display information on gas stations with the highest number of visits by specific customers, gas stations located at the shortest distance from the current location, gas stations with the lowest gasoline prices, etc.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) starts providing route guidance to the gas station displayed in the first recommendation result display area (502). That is, based on a quick execution voice command generated by the driver, control corresponding to the quick execution voice command can be performed quickly without a separate selection process by the driver. In contrast, if the driver selects one of the multiple gas stations displayed in the second recommendation result display area (504) within a predetermined time (5 seconds), the control unit (312) starts providing route guidance to the gas station selected by the driver. That is, if the driver prefers the recommended results displayed in the second recommendation result display area (504) to the recommended results displayed in the first recommendation result display area (502), the driver can quickly perform the desired control (destination selection and route guidance) by simply touching the second recommendation result display area (504) of the display (214).

FIG. 7 is a diagram showing a second example of displaying a system recommendation result when a voice command is performed by a vehicle according to an embodiment of the present invention. The example shown in FIG. 7 is a case where a driver utters “Guide me to a cheap gas station near Yangjae Station that is ‘fast’” to generate a voice command for guidance to a gas station. Here, ‘fast’ is a prefix indicating that it is a fast-execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays the recommended results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), as shown in FIG. 7.

The first recommendation result display area (502) of Fig. 7 displays information on the gas station with the lowest gasoline price. If the driver's vehicle (100) is a diesel vehicle or an LPG vehicle, information on the gas station with the lowest diesel or LPG price may be displayed in the first recommendation result display area (502).

The second recommendation result display area (504) of Fig. 7 displays information on gas stations with higher gasoline prices than the gas stations displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display information on gas stations with gasoline prices of 1,530 won per liter, gas stations with gasoline prices of 1,560 won per liter, gas stations with gasoline prices of 1,600 won per liter, and the like.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) starts providing route guidance to the gas station displayed in the first recommendation result display area (502). That is, based on a quick execution voice command generated by the driver, control corresponding to the quick execution voice command can be performed quickly without a separate selection process by the driver. In contrast, if the driver selects one of the multiple gas stations displayed in the second recommendation result display area (504) within a predetermined time (5 seconds), the control unit (312) starts providing route guidance to the gas station selected by the driver. That is, if the driver prefers the recommended results displayed in the second recommendation result display area (504) to the recommended results displayed in the first recommendation result display area (502), the driver can quickly perform the desired control (destination selection and route guidance) by simply touching the second recommendation result display area (504) of the display (214).

FIG. 8 is a diagram showing a third example of displaying a system recommendation result when a voice command is executed by a vehicle according to an embodiment of the present invention. The example shown in FIG. 8 is a case where a driver utters “Send a text message to ‘fast’ Tae-sik Oh” to send a text message to a specific recipient registered in the phone book of the AVN (200). Here, ‘fast’ is a prefix indicating a fast execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays, as shown in FIG. 8, the recommendation results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), respectively.

The first recommendation result display area (502) of Fig. 8 displays information on the recipient to whom a text message was most recently sent.

The second recommendation result display area (504) of FIG. 8 displays information on other recipients to whom text messages were sent earlier than the recipients displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display information on a recipient who sent a text message on July 24, which is earlier than July 31, when the text message was sent to the recipient in the first recommendation result display area (502), or a recipient who sent a text message on April 1, which is earlier than that. Alternatively, information on a recipient who has no recent text message exchange history as the lowest priority may also be displayed.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) can create a text message transmission environment so that a text message can be transmitted to the recipient displayed in the first recommendation result display area (502). In this case, since the driver is driving, the content of the text message can be input based on the driver's speech and voice recognition function. In other words, the control corresponding to the quick execution voice command can be quickly performed without a separate selection process by the driver based on the quick execution voice command generated by the driver. In contrast, if the driver selects any one of the multiple recipients displayed in the second recommendation result display area (504) within the predetermined time (5 seconds), the control unit (312) creates an environment for transmitting a text message to the recipient selected by the driver. That is, if the driver prefers the recommendation results displayed in the second recommendation result display area (504) over the recommendation results displayed in the first recommendation result display area (502), the driver's desired control (text transmission) can be quickly achieved by simply touching the second recommendation result display area (504) of the display (214).

FIG. 9 is a diagram showing a fourth example of displaying a system recommendation result when a voice command is executed by a vehicle according to an embodiment of the present invention. The example shown in FIG. 9 is a case where a driver utters “Call Tae-sik Oh, who I spoke to yesterday, ‘quickly’” to send a text message to a specific recipient registered in the phone book of the AVN (200). Here, ‘quickly’ is a prefix indicating that it is a quick execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays the recommended results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), as shown in FIG. 9.

The first recommendation result display area (502) of Fig. 9 displays information on the most recent caller.

The second recommendation result display area (504) of Fig. 9 displays information on callers with a different priority from the callers displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display information on callers who called on July 17, which is earlier than August 3, the caller in the first recommendation result display area (502), or on May 3, which is earlier than that. Alternatively, information on callers with the lowest priority and who have not recently exchanged calls may also be displayed.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) makes a call to the caller displayed in the first recommendation result display area (502). That is, based on a quick execution voice command generated by the driver, control corresponding to the quick execution voice command can be performed quickly without a separate selection process by the driver. In contrast, if the driver selects one of the multiple callers displayed in the second recommendation result display area (504) within a predetermined time (5 seconds), the control unit (312) makes a call to the caller selected by the driver. That is, if the driver prefers the recommended results displayed in the second recommendation result display area (504) to the recommended results displayed in the first recommendation result display area (502), the driver can quickly perform the desired control (making a call) by simply touching the second recommendation result display area (504) of the display (214).

Fig. 10 is a diagram showing a fifth example of displaying a system recommendation result when a voice command is executed by a vehicle according to an embodiment of the present invention. The example shown in Fig. 10 is a case where a driver utters “Open the ‘quick’ window” to generate a voice command to close the window of a vehicle (100). Here, ‘quick’ is a prefix indicating a quick execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays, as shown in FIG. 10, the recommendation results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), respectively.

The first recommendation result display area (502) of Fig. 10 displays settings for opening the window of the driver's seat. Since the seat with the highest frequency of seating among the seats of the vehicle (100) is the driver's seat, the frequency of opening the window of the driver's seat is also relatively higher than that of the windows of other seats. Accordingly, the first recommendation result display area (502) displays settings for opening the window of the driver's seat with the highest frequency of opening.

The second recommendation result display area (504) of Fig. 10 displays information on gas stations with higher priority than the window opening settings displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display settings for opening the windows of all seats (front seats) including the driver's seat and the passenger's seat, settings for opening all windows of the vehicle (100) (all windows of the driver's seat, passenger's seat, and the rear seat), etc.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) opens the driver's window, which is the window displayed in the first recommendation result display area (502). In other words, based on a quick execution voice command issued by the driver, control corresponding to the quick execution voice command can be performed quickly without a separate selection process by the driver. In contrast, if the driver selects one of the multiple window opening settings displayed in the second recommendation result display area (504) within a predetermined time (5 seconds), the control unit (312) controls the corresponding windows to be opened according to the window opening setting selected by the driver. In other words, if the driver prefers the recommended results displayed in the second recommendation result display area (504) to the recommended results displayed in the first recommendation result display area (502), the driver's desired control (opening of a specific window) can be quickly performed with a simple operation of simply touching the second recommendation result display area (504) of the display (214).

Fig. 11 is a diagram showing a sixth example of displaying a system recommendation result when a voice command is executed in a vehicle according to an embodiment of the present invention. The example shown in Fig. 11 is a case where a driver utters “Turn on the ‘quick’ air conditioner” to generate a voice command to turn on the air conditioner of a vehicle (100). Here, ‘quick’ is a prefix indicating a quick execution voice command according to an embodiment of the present invention.

When a quick execution voice command is generated by the driver's speech, the display (214) of the AVN (200) displays, as shown in FIG. 11, the recommendation results recommended by the system (AVN) based on the quick execution voice command in the first recommendation result display area (502) and the second recommendation result display area (504), respectively.

The first recommendation result display area (502) of Fig. 11 displays the operating conditions recently set for the air conditioner. For example, if the most recent air conditioner setting is 18°C for temperature, 3 for wind speed, and 'up/down' for wind direction, the control unit (312) displays this recent setting in the first recommendation result display area (502). There is bound to be an air conditioner setting that the driver usually prefers, and there is a high probability that the most recent setting is the driver's preferred setting. Therefore, the first recommendation result display area (502) displays the most recent air conditioner setting.

The second recommendation result display area (504) of Fig. 11 displays air conditioner settings that are different from the air conditioner settings displayed in the first recommendation result display area (502). For example, the second recommendation result display area (504) may display settings such as temperature being 'LOWEST', wind speed being 3, and wind direction being 'up/down', temperature being 18°C, wind speed being 7, and wind direction being 'up'.

If the driver does not make any selection after a predetermined time (e.g., 5 seconds), the control unit (312) operates the air conditioner with the setting displayed in the first recommendation result display area (502). In other words, control corresponding to the quick execution voice command can be performed quickly without a separate selection process by the driver based on the quick execution voice command generated by the driver. In contrast, if the driver selects any one of the plurality of air conditioner settings displayed in the second recommendation result display area (504) within the predetermined time (5 seconds), the control unit (312) controls the air conditioner to operate according to the air conditioner setting selected by the driver. In other words, if the driver prefers the recommendation result displayed in the second recommendation result display area (504) to the recommendation result displayed in the first recommendation result display area (502), the driver's desired control (operation of the air conditioner with a specific setting) can be quickly performed with a simple operation of simply touching the second recommendation result display area (504) of the display (214).
