FIG. 9 is a flowchart illustrating a representative control method of the present invention, and FIGS. 10, 11, 12, 13, and 14 are conceptual views illustrating the control method described with reference to FIG. 9.

Referring to FIG. 9, first, in the present invention, a step of sensing sound through the sensing unit 810 is performed (S910). In detail, the processor 870 may control the sensing unit 810 to sense sound.

At this time, the processor 870 may activate the sensing unit 810 to sense the sound based on the predetermined condition being satisfied.

Here, the preset condition is, for example, when there is a user request (or user input) to execute the mode for controlling the vehicle so that the volume of the sound generated by the driving of the vehicle does not exceed the preset volume, the inside of the vehicle If the user's status is a preset state (e.g., a sleep state, a reading state, a phone state, or when a plurality of users are in a conversation for a predetermined time or the like), the preset function (e.g., a video conference function or video playback) , Music playback, etc.) or when the state of the road surface being changed is changed (for example, when the road surface is turned into an asphalt road and becomes a dirt road, or rain or snow falls, etc.), Various conditions may be included, such as when converted.

The preset condition may be preset at the time of product release, or may be added / deleted or changed by a user's setting.

In addition, the processor 870 may control the sensing unit 810 such that the sensing unit 810 senses a sound every predetermined period or at all times.

In operation S920, the present invention identifies a sound generated by driving of the vehicle among the sensed sounds.

In detail, when a sound is sensed through the sensing unit 810, the processor 870 may classify the sensed sound into a sound generated by driving of the vehicle and a sound unrelated to driving of the vehicle.

For example, the sound generated by driving of the vehicle may include a sound generated by the engine, a wind blowing sound, a road friction sound, and the like. In addition, sounds that are not related to driving of the vehicle may include content sounds, human voices, surrounding vehicle sounds, ambient sounds, and the like.

Information regarding the type of sound generated by driving of the vehicle may be determined / changed by user setting, may be stored in the memory 140 of the vehicle 100, or the communication of the vehicle 100 may be performed. The device 400 may be received / stored / determined through an external server (eg, a cloud).

Thereafter, the present invention is a step of controlling the vehicle so that the volume of the sound generated by the driving of the vehicle does not exceed the preset level (S930).

Specifically, the processor 870 is based on the sound generated by the driving of the vehicle among the sounds sensed by the sensing unit 810, so that the volume of the sound generated by the driving of the vehicle does not exceed a preset size. 100 can be controlled.

In general, the loudness (eg, wind noise, engine sound, road friction sound, etc.) generated by driving of the vehicle may be proportional to the speed of the vehicle. That is, the volume of sound generated by driving of the vehicle may increase as the speed of the vehicle increases, and decrease as the speed of the vehicle decreases.

As an example, the processor 870 may not exceed a preset loudness (eg, dB) in the sensed sound generated by driving of the vehicle (eg, dB (decibel)). The driving speed of the vehicle can be controlled.

The predetermined size may be any value or may be a range having a second value from the first value. The preset size may be determined or changed by user setting.

On the other hand, controlling the vehicle such that the volume of the sound generated by the driving of the vehicle among the sensed sounds does not exceed a predetermined size (or smaller than the predetermined size) may be defined in the form of a mode.

Such a mode refers to a mode in which the vehicle is controlled so that the volume of the sound generated by the driving of the vehicle does not exceed a preset volume, and may be referred to as a silent mode or a silent driving mode for convenience.

The processor 870 may enter a mode for controlling the vehicle such that the volume of the sound generated by the driving of the vehicle does not exceed the preset volume, based on the satisfaction of the preset condition.

That is, when the mode is entered, the processor 870 may control the vehicle so that the volume of the sound generated by the driving of the vehicle does not exceed the preset volume.

The preset condition set to enter (or associated with) the mode may be analogously applied similarly to the preset condition described above.

Once again, the preset condition is, for example, when there is a user request (or user input) for executing a mode for controlling the vehicle so that the volume of sound generated by the driving of the vehicle does not exceed the preset volume. When the user's state inside the vehicle is a preset state (for example, a sleep state, a reading state, a phone state, or when a plurality of users are talking for a predetermined time or the like), a preset function (for example, a video conference function). , Video playback, music playback, etc.), or when the state of the road surface being changed is changed (for example, when the road surface is turned into an asphalt road, becomes a dirt road, rain or snow falls, etc.) Various conditions may be included, such as when the driving mode is switched.

In addition, the predetermined condition is that the driver or passenger is sleeping in the autonomous driving mode, the driver or passenger is reading or calling, the driver and passenger are talking for a certain time, or the driving noise is increased by a certain size or more. And the like.

The processor 870 may determine (determine) whether the preset condition is satisfied based on the information sensed by the sensing unit 810.

Thereafter, the processor 870 may enter a mode for controlling the vehicle such that the volume of the sound generated by the driving of the vehicle does not exceed the preset level based on the satisfaction of the preset condition.

The processor 870 may control (or activate) the sensing unit 810 to sense the sound based on entering the mode.

For example, when the voice input unit 211 of the sensing unit 810 is deactivated and the preset condition is satisfied, the processor 870 enters the mode and based on entering the mode, The voice input unit 211 may be activated.

Thereafter, the processor 870 may sense a sound through the voice input unit 211, and control the vehicle such that a volume of the sound generated by driving of the vehicle is smaller than a preset size.

Meanwhile, when the preset condition is satisfied, the processor 870 may output a notification window to the display unit 820 to confirm whether to enter the mode.

Subsequently, based on receiving a user input of entering the mode in the state in which the notification window is output, the processor 870 controls the vehicle not to exceed the preset volume of the sound generated by driving of the vehicle. The mode can be entered.

Referring to FIG. 10, as illustrated in FIG. 10A, the processor 870 may detect a preset condition (eg, a user request is received or a preset function (video) through the sensing unit 810. Playback 1000a or video conferencing function 1000c), the driver or passenger is sleeping (1000b), the state of the road surface being changed (1000d), or the driving noise increases by a certain amount). It can be determined (judged) whether it is satisfied.

Thereafter, when the preset condition is satisfied (when any one of the preset conditions is satisfied), the processor 870 controls the vehicle so that the volume of sound generated by driving of the vehicle does not exceed the preset level. The notification window 1010 for checking whether to enter may be output to the display unit 820.

Thereafter, the processor 870 may enter the mode based on a user input indicating that the user enters the mode while the notification window 1010 is output.

In this case, as shown in FIG. 10C, when the processor enters the mode, the processor 870 includes at least one of a sound sensed by the sensing unit 810 or a sound generated by driving of the vehicle. The display unit 820 may be controlled such that the graphic object 1020 indicating the size is output to the display unit 820.

For example, the display unit 820 may be a cluster, and the display unit 820 may output a first graphic object indicating a speed of a vehicle and / or a second graphic object indicating a rpm of a vehicle engine. Can be.

In this case, when the mode is entered, the display unit 820, together with the above-described first and second graphic objects, includes a sound sensed by the sensing unit 810 or a sound generated by driving of the vehicle. The graphic object 1020 indicating at least one size (decibel) may be further output.

As another example, when entering the mode, the graphic object 1020 may be output to the display unit 820 instead of at least one of the first and second graphic objects. In this case, at least one of the first and second graphic objects may not be output.

However, the present disclosure is not limited thereto, and the processor 870 may directly enter the mode based on the satisfaction of the preset condition.

When the processor 870 enters the mode, the processor 870 may control (eg, autonomous driving) the vehicle 100 such that the volume of the sound generated by the driving of the vehicle does not exceed a preset level.

The processor 870 may set the preset size differently according to a type of a preset condition for entering the mode. For example, the preset size may be linked for each type of the preset condition.

For example, when a first type (for example, driver / passenger sleep) is satisfied among the preset conditions, the processor 870 may determine that the volume of sound generated by driving of the vehicle is the first of the preset sizes ( For example, the vehicle can be controlled not to exceed 40 dB).

As another example, when a second type (for example, video playback) different from the first type is satisfied among the preset conditions, the processor 870 may determine that the volume of sound generated by driving of the vehicle is one of the preset sizes. The vehicle may be controlled not to exceed a second size different from the first size (for example, 60 dB).

With such a configuration, the present invention does not only enter the silent mode based on satisfying the preset condition, but also according to the type of the preset condition. ) Can provide an optimized silent mode that can be set differently.

On the other hand, the mode is a first mode for controlling the vehicle (driving or autonomous driving) so that the volume of the sound generated by the running of the vehicle is less than the preset volume, and the sound generated by the running of the vehicle And a second mode of controlling the vehicle 100 to maintain the size at the preset size.

Here, in the first mode, as shown in FIG. 11A, a range in which the volume of the sound generated by driving of the vehicle is equal to or less than a predetermined size (for example, 80 dB) (for example, 0 to 1). 80dB) refers to the mode of controlling the vehicle (driving or autonomous driving). The first mode may be referred to as 'dB limit mode'.

In the second mode, as shown in FIG. 11B, the vehicle 100 is controlled (driving) such that the volume of sound generated by driving of the vehicle is maintained at a preset level (for example, 65 dB). Or autonomous driving). The second mode may be referred to as 'dB Cruise mode'.

That is, the processor 870 of the present invention may enter one of the first mode and the second mode when the preset condition is satisfied.

For example, when the vehicle enters the first mode while the vehicle is in autonomous driving mode, the processor 870 may cause the volume of the sound generated by the driving of the vehicle to exceed (or exceed) the preset volume. Range)) to control the vehicle (autonomous driving). In general, the first mode may be utilized in general roads, downtowns, national roads, and the like, where speeds are accelerated and decelerated.

As another example, when the vehicle enters the second mode while the vehicle is in the autonomous driving mode, the processor 870 controls the vehicle to maintain the volume of the sound generated by the driving of the vehicle at a preset level (autonomous driving). can do. In general, the second mode may be utilized on roads where a constant speed can be driven for a predetermined time or more, such as a highway.

The processor 870 may enter the first mode or the second mode based on a type of a preset condition. In addition, the processor 870 may enter the first mode or the second mode based on a user selection. In addition, the processor 870 may determine the first mode or the like based on the type of road on which the vehicle 100 is traveling or the state of the road on which the vehicle 100 is driving (whether or not the vehicle density is equal to or higher than a predetermined value, or the surrounding weather). A second mode may be entered.

As illustrated in FIG. 11, the display unit 820 may differently display graphic objects representing the magnitude of at least one of a sound sensed by each of the first mode or the second mode or a sound generated by driving of the vehicle. have.

In detail, when entering the first mode, the processor 870 may output the first graphic object 1020a corresponding to the first mode as illustrated in FIG. 11A.

In addition, when the processor 870 enters the second mode, as illustrated in FIG. 11B, the processor 870 may output a second graphic object 1020b corresponding to the second mode.

When entering the second mode, an indicator 1022 indicating a preset size of the second graphic object 1020b output to the display unit 820 may be output.

The processor 870 may control (autonomous driving) the vehicle such that the volume of the sound generated by driving of the vehicle is maintained at the volume of the sound corresponding to the position at which the indicator 1022 is output.

In addition, the processor 870 may change the preset size based on a user input. In this case, the indicator 1022 may be output at a position corresponding to the changed preset size. That is, the display position of the indicator 1022 may vary based on the change in the preset size, and may be moved (changed) to a position corresponding to the changed preset size.

As described above, the present invention subdivides the silent mode so that the dB limit mode for controlling the vehicle and the volume of the sound generated by the driving of the vehicle are preset in the volume of the sound generated by the driving of the vehicle. It can provide a new vehicle driving mode called dB Cruise mode, which controls the vehicle to remain.

Meanwhile, in the vehicle control apparatus 800 of the present invention, first route information may be set. The first route information may mean route information for reaching a destination input by a user from a current position of the vehicle 100.

In this case, the first route information is route information that can arrive at the destination in the shortest time to reflect the real-time traffic situation, route information that can reach the destination in the shortest distance, or can arrive at the destination using only the free road. It may be route information or route information that may arrive at a destination using a comfortable road (for example, a highway, a road having a certain number of traffic lights or less). The first route information may be set in the navigation system 770, and the processor 870 may control the navigation system 770.

As shown in FIG. 12A, in the state in which the first route information is set, the vehicle control apparatus 800 controls the vehicle so that the loudness of the sound generated by driving of the vehicle does not exceed a preset level. The mode may be entered.

In this case, as illustrated in (b) of FIG. 12, the processor 870 may search for the second route information capable of traveling so that the loudness of the sound generated by the driving of the vehicle does not exceed the preset size. have.

For example, the processor 870 may drive the vehicle 100 to the destination based on map information previously stored in the navigation system 770 or the memory 140 or map information received through communication with an external server. In this case, the road capable of driving may be selected so that the sound generated by the driving of the vehicle does not exceed a preset size, and the second route information may be searched (set, generated) using the selected road.

Thereafter, as shown in FIG. 12B, when the processor 870 enters the mode in a state where the first route information is set, the processor 870 may preset the volume of sound generated by driving of the vehicle. Information 1200b related to the second route information and information 1200a related to the first route information may be output to the display unit 820 (or the navigation system 770).

The

information

1200a and 1200b related to the first and second route information may include information such as a driving time, a driving distance, an average loudness of the sound generated when driving the corresponding route, and a maximum loudness of the sound.

Information about the volume of sound generated when driving the corresponding path may be received by an external server (or cloud). For example, the external server (or cloud) may receive sound volume information generated by the driving of the vehicle from another vehicle currently driving on each road included in the corresponding path. Based on this, the processor 870 receives the loudness information on the road corresponding to the second route information from an external server, and based on this, the average loudness of the sound generated when driving the corresponding route or the highest of the sounds. The size can be calculated.

Subsequently, when one of the information 1200a related to the first path information and the information 1200b related to the second path information is selected, the processor 870 selects a vehicle based on the path information corresponding to the selected information. Can control (autonomous driving)

Further, when one of the information 1200a related to the first path information and the information 1200b related to the second path information is selected, the processor 870 selects the selected one as shown in FIG. 12C. The route information 1210 corresponding to the information may be output to the display unit 820 (or on the map information).

As such, the present invention may provide a new user interface capable of selecting (or changing) route information of a vehicle such that a sound generated by driving of the vehicle is less than or equal to a preset size.

On the other hand, as described above, the loudness generated by the driving of the vehicle may be proportional to the traveling speed of the vehicle. For example, if the running speed of the vehicle is the first speed, the loudness is the first loudness, and if the running speed of the vehicle is the second speed slower than the first speed, the loudness is greater than the first magnitude. It may be a small second size.

The processor 870 controls the vehicle 100 based on the speed limit regardless of the loudness of the sound generated by the vehicle when the vehicle 100 is determined to be driving on the road on which the speed limit is defined. (Autonomous driving)

For example, as shown in FIG. 13A, the vehicle 100 may be driving on a road on which a speed limit is defined. The speed limit may include a maximum speed 1300a and a minimum speed 1300b.

When the vehicle 100 enters a mode for controlling the vehicle such that the volume of the sound generated by the driving of the vehicle is smaller than the preset volume while driving on the road where the speed limit is defined, the preset volume (or It may be a problem of controlling the vehicle based on the generated sound) or controlling the vehicle based on the speed limit.

For example, when it is necessary to drive the vehicle 100 at a first speed in order to control the vehicle such that the volume of the sound generated by the driving of the vehicle is smaller than a preset volume, the first speed may be lower than the minimum speed. have. Here, the first speed may mean a maximum traveling speed of the vehicle such that the volume of the sound generated by the driving of the vehicle becomes a preset loudness.

This may be an embodiment in the first mode described above. For example, when the preset magnitude is set to a first value (for example, a value smaller than the volume of sound generated when the vehicle runs at the minimum speed), the first speed may be slower than the minimum speed of the speed limit. Can be. In this case, since the vehicle must be driven at a speed slower than the speed limit, traffic congestion or accident risk increases.

When the speed limit is the minimum speed 1300b, the processor 870 may generate the minimum speed even if the loudness generated by the vehicle traveling when the vehicle travels at the minimum speed is greater than the preset level. The vehicle may be autonomous.

In other words, even if the processor 870 enters the mode, the (maximum) speed of the vehicle such that the volume of the sound generated by the driving of the vehicle is smaller than the preset loudness is the first speed, and the first speed is increased. When lower than the minimum speed, the vehicle may be controlled (autonomous driving) at the minimum speed instead of the first speed.

In other words, even when the vehicle enters the mode, when the vehicle is driving on the road on which the speed limit is defined, the vehicle control apparatus 800 may control the vehicle based on the speed limit.

In addition, in the above-described second mode, the speed of the vehicle such that the volume of the sound generated by the driving of the vehicle is maintained at the preset level may be the second speed. At this time, the second speed may exceed the maximum speed of the speed limit. For example, when the preset size is set to a second value (eg, a value greater than the volume of sound generated when the vehicle runs at the highest speed), the second speed may be faster than the maximum speed.

In this case, the processor 870, the speed of the vehicle to maintain the volume of the sound generated by the running of the vehicle at a predetermined volume, the second speed is exceeding the maximum speed of the speed limit In this case, the vehicle may be controlled (autonomous driving) at the maximum speed instead of the second speed.

In addition, even when the vehicle enters the mode, when the vehicle is driving on the road where the speed limit is defined, it may be understood that the vehicle control apparatus 800 controls the vehicle based on the speed limit.

As illustrated in (b) of FIG. 13, the processor 870 may control (autonomous driving) the vehicle at the minimum speed even if the volume of the sound generated by the driving of the vehicle is greater than the preset volume.

In this case, the volume of the sound generated by the current driving of the vehicle may be output to the graphic object 1020 on the display unit 820. In addition, the processor 870 controls the graphic object 1020 to notify that the loudness of the sound is greater than a preset size, and indicates information (for example, why the loudness of the sound is larger than the preset loudness). 1300 may be output to the display unit 820.

Thereafter, when the vehicle 100 leaves the road where the speed limit is defined, the processor 870 may have a loudness greater than a preset level as shown in FIG. 11C. The vehicle can be autonomous to be small.

Through this configuration, the present invention can provide a new control method that can control the vehicle in consideration of the speed limit when entering the silent mode on the road where the speed limit is defined.

On the other hand, while the vehicle is in the manual driving mode, the processor 870 may enter a mode for controlling the vehicle such that the sound generated by the driving of the vehicle is smaller than the preset size based on the satisfaction of the preset condition. have.

In this case, as shown in FIG. 14, the display unit 820 may include a HUD.

In addition, when the processor 870 enters the mode in the manual driving mode, the processor 870 may display the graphic object 1400 for guiding the vehicle driving path such that the volume of sound generated by driving of the vehicle does not exceed a preset level. The display may be output to a display unit (eg, a HUD).

Through this configuration, the present invention provides a new user interface that allows a driver to drive a vehicle along the graphic object 1400, so that the driver can manually drive the vehicle so that the volume of sound generated by the driving of the vehicle does not exceed a preset level. Can be provided.

The vehicle control apparatus 800 described above may be included in the vehicle 100.

In addition, the operation or control method of the vehicle control apparatus 800 described above may be analogously applied to the operation or control method of the vehicle 100 (or the control unit 170).

For example, the control method of the vehicle 100 (or the control method of the vehicle control apparatus 800), the step of sensing the sound, the sound generated by the driving of the vehicle among the sound sensed through the sensing unit is identified. And controlling the vehicle such that the volume of the sound generated by driving of the identified vehicle does not exceed a preset level.

Each of the above steps may be performed by the controller 170 provided in the vehicle 100 as well as the vehicle control apparatus 800.

In addition, all functions, configurations, or control methods performed by the vehicle control apparatus 800 described above may be performed by the controller 170 provided in the vehicle 100. That is, all the control methods described herein may be applied to the control method of the vehicle or may be applied to the control method of the control device.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded.
