Referring to FIG. 9 , first of all, according to the present disclosure, the process of sensing information associated with a vehicle through the sensing unit is carried out (S 910 ).
Specifically, periodically or when a specific condition occurs, the processor 170 may always activate the sensing unit 860 , and sense information associated with the vehicle through the sensing unit 860 .
Here, the information associated with the vehicle may include vehicle information (or driving status of the vehicle), surrounding information of the vehicle, and the like.
Furthermore, the information associated with the vehicle may include various conditions/situations disclosed herein.
Then, according to the present disclosure, the process of adjusting (changing) the transparency of the windshield based on that the sensed information satisfies a preset condition is carried out (S 920 ).
Specifically, when information associated with the vehicle is sensed through the sensing unit 860 , the processor 870 may determine (decide, detect, extract, sense) whether or not the information associated with the vehicle satisfies a preset condition.
Here, the preset condition may include various conditions as a preset condition to vary the transparency of the windshield.
For an example, the various conditions may include whether or not a driving speed of the vehicle is above a predetermined speed, whether or not a user approaches a reference region based on the vehicle, whether or not the approaching user is an authenticated user, whether or not another user approaches in a state that an authenticated user gets in the vehicle, a surrounding brightness of the vehicle, whether or not a preset object exists within a predetermined distance from the vehicle, whether or not a preset type of user input (or gesture) is received, and the like.
The transparency of the windshield in the present specification may vary within a reference range (for example, a range permitted by law regulations), for an example. For an example, the transparency may vary within a range of light transmittance of 70-100% in case of a front windshield (front glass), and the transparency may vary within a range of light transmittance of 40-100% in case of a left and a right windshield.
Hereinafter, a method of adjusting the transparency of the windshield when a preset condition is satisfied will be described in more detail with reference to the accompanying drawings.
The processor 870 of the vehicle control device 800 associated with the present disclosure may change the transparency of the windshield 810 when a driving speed of the vehicle 100 varies by a predetermined speed.
For example, as illustrated in FIG. 11A , the processor 870 may set the transparency of the windshield 810 to a first transparency when the speed of the vehicle 100 is a first speed (for example, 0 km/h).
As illustrated in FIG. 11B , when the speed of the vehicle 100 is changed to a second speed (for example, 30 km/h) different from the first speed as illustrated in FIG. 11B , the processor 870 may change the transparency of the windshield 810 to a second transparency different from the first transparency.
For another example, when the speed of the vehicle is less than a predetermined speed, the processor 870 of the present disclosure may control the windshield to allow the transparency of the windshield 810 to be a first transparency (for example. light transmittance of 40%). Furthermore, when the speed of the vehicle is above a predetermined speed, the processor 870 may change the transparency of the windshield 810 to be a second transparency (for example. light transmittance of 100%) different from the first transparency.
The processor 870 associated with the present disclosure may change the transparency of the windshield 810 when a variation amount of the vehicle driving speed is above a predetermined amount, and determine the transparency of the windshield 810 according to whether or not the driving speed of the vehicle is greater or less than a predetermined speed.
Furthermore, the processor 870 may vary the transparency of the windshield 810 in proportion to the driving speed of the vehicle or vary the transparency of the windshield 810 in inverse proportion to the driving speed of the vehicle.
Furthermore, the processor 870 may maintain the transparency of the windshield to be a first transparency below a first speed, maintain the transparency of the windshield to be a second transparency different from the first transparency, and vary the transparency of the windshield in proportion or inverse proportion to the speed of the vehicle between the first speed and the second speed.
When the transparency of the windshield varies based on the satisfaction of a preset condition, it may be possible to have various design changes to change it to be more transparent or non-transparent, and may be determined according to the user's setting or determined by the control of the processor (or controller).
The present disclosure may not be necessarily limited to embodiments disclosed herein, and it should be noted that the present disclosure may be also applicable in an inverse manner to the description disclosed herein. For example, when it is described in the present disclosure that the transparency of the windshield is changed to be more transparent as the speed of the vehicle increases, it should be understood that a case where the transparency of the windshield is changed to be more non-transparent as the speed of the vehicle increases is included in the scope of the present disclosure.
As described above, the present disclosure may provide a new windshield control method capable of varying the transparency of the windshield when the speed of the vehicle is sensed through the sensing unit, and the speed of the vehicle varies by a predetermined speed (or the speed of the vehicle is above a predetermined speed).
Referring to FIG. 12A , the processor 870 associated with the present disclosure may sense a user approaching the vehicle 100 through the sensing unit 860 . Then, when the sensed user enters a reference region based on the vehicle 100 , the processor 870 may change the transparency of the windshield.
Here, the reference region (A) may denote a predetermined region (space) based on the vehicle.
The reference region (A) may be set in various ways. For an example, the reference region may be a region capable of sensing an object through the sensing unit 860 or a space existing within a predetermined distance with respect to the vehicle 100 or a preset region.
When it is sensed through the sensing unit 860 that a user enters the reference region (A), the processor 870 may change the transparency of the windshield 810 . For example, when the user enters within the reference region (A) in a state that that the transparency of the windshield 810 is a first transparency (for example, light transmittance of 40%), the processor 870 may change the transparency to a second transparency (for example, light transmittance of 100%) different from the first transparency.
On the other hand, the transparency of the windshield may be changed when the sensed user is an authenticated user.
Here, the processor 870 of the vehicle 100 may determine whether or not the sensed user is an authenticated user in various methods.
For an example, when it is connected to the user's mobile terminal 1200 to enable wireless communication through the communication unit of the vehicle or the mobile terminal 1200 connected to enable wireless communication is a terminal that has successfully completed an authentication process in advance (subsequent to the entry), the processor 870 may determine the user who possesses the mobile terminal 1200 as an authenticated user.
For another example, when the user enters the reference region (A), the processor 870 may transmit a signal for checking whether or not there is an authenticated terminal, and when there is a response to the signal from the user's mobile terminal 1200 , the processor 870 may determine the user as an authenticated user. Here, the response may be a response signal transmitted from a previously authenticated mobile terminal when the terminal receives the signal.
For still another example, the processor 870 may determine whether or not a user who has entered the reference region (A) is an authenticated user using a camera or determine whether or not a user who has entered the reference region (A) is an authenticated user using a fingerprint recognition sensor, an iris recognition sensor or the like.
When a user who has entered the reference region (A) is an authenticated user, for an example, the processor 870 may change a non-transparent windshield 810 to be transparent. Here, being non-transparent may denote a case where light transmittance is less than a first reference value, and being transparent may denote a case where light transmittance is greater than a second reference value.
The first and the second reference value may be the same value or different values, and when they are different, the first reference value may be larger than the first reference value.
For an example, when an authenticated user (P 1 ) enters the reference region (A) in a state that the transparency of the windshield 810 is a first transparency as illustrated in FIG. 12A (a), the processor 870 may change the transparency of the windshield 810 from the first transparency to a second transparency as illustrated in FIG. 12A (b).
On the other hand, the present disclosure may not be necessarily limited to changing the transparency of the windshield only when a user who has entered the reference region (A) is an authenticated user. The present disclosure may change the transparency of the windshield even when an unauthenticated user enters the reference region (A).
Hereinafter, a case where a user entering the reference region (A) is an authenticated user and a case where the user entering the reference region (A) is an unauthenticated user will be described in a distinguished manner, but the description thereof may be modified and applied in various ways regardless of whether or not the user is authenticated.
On the other hand, the windshield 810 associated with the present disclosure may be a plural number 810 a , 810 b.
As illustrated in FIG. 12A (c), when the sensed approaches the vehicle, the processor 870 may determine a direction in which the sensed user approaches the vehicle.
The processor 870 may change the transparency of one 810 a of the plurality of windshields 810 a , 810 b based on a direction in which the sensed user (for example, authenticated user (P 1 )) approaches the vehicle 100 .
For example, the processor 870 may change the transparency of at least one windshield 810 a of the plurality of windshields 810 a , 810 b disposed in a direction in which the user (P 1 ) approaches.
For an example, when a user (for example, an authenticated user) approaches the left side of the vehicle, the windshield 810 disposed at the left of the vehicle may be changed from a first transparency to a second transparency different from the first transparency.
On the other hand, when an unauthenticated user approaches the vehicle 100 , (for example, when enters the reference region (A)), the processor 870 may maintain the transparency of the windshield 810 with no change.
However, as illustrated in FIG. 12B (a), when an unauthenticated user (P 2 ) enters the reference region (A) in a state that an authenticated user (P 1 ) exists within (gets in) the vehicle 100 , the processor 870 may change the transparency of the windshield as illustrated in FIG. 12B (b).
For an example, the processor 870 may change the transparency of the windshield located in a direction in which the unauthenticated user approaches from a first transparency to a second transparency different from the first transparency based on a direction in which the unauthenticated user approaches the vehicle 100 among a plurality of windshields.
For an example, when an unauthenticated user approaches the vehicle 100 (when the unauthenticated user enters the reference region (A)) in a state that an authenticated user gets in the vehicle (or an authenticated user exists in the reference region (A)), the processor 870 may control the transparency of the windshield to be transparent.
As described above, even if an authenticated user does not exist within the reference region (A), the processor 870 may change the transparency of the windshield based on an unauthenticated user (P 2 ) entering the reference region (A).
For example, when an unauthenticated user (P 2 ) enters the reference region (A) in a state that the transparency of the windshield 810 is a first transparency (for example, light transmittance of 100%) as illustrated in FIG. 12C (a), the processor 870 may change the windshield with the first transparency to a second transparency (for example, light transmittance of 40%) that is more non-transparent than the first transparency as illustrated in FIG. 12C (b).
Here, the processor 870 may change the transparency of a windshield 810 d disposed to correspond to a direction in which the unauthenticated user (P 2 ) approaches among a plurality of windshields. Here, the transparency of the windshield 810 d may be changed to be non-transparent.
On the other hand, though not shown in the drawing, when an authenticated user and an unauthenticated user enter the reference region (A) (approach the vehicle) at the same time, the processor 870 may change the transparency of the windshield 810 to be a lower transparency (for example, light transmittance of 70% or semi-transparent) than that of a case where only the authenticated user approaches (for example, light transmittance of 100%).
In other words, assuming that a first transparency set to the windshield in case where only the authenticated user approaches is 100%, and a second transparency set to the windshield in case where only the unauthenticated user approaches is 40%, the transparency of the windshield may be set to a third transparency between the first transparency and the second transparency.
Even when the authenticated user and the unauthenticated user approach the vehicle at the same time, the processor 870 may set the third transparency to be different according to a number of authenticated users and a number of unauthenticated users. For an example, the third transparency may increase light transmittance as a number of authenticated users increases, and decrease light transmittance as a number of unauthenticated users increases.
Through the foregoing configuration, the present disclosure may provide a vehicle and a vehicle control device provided with a windshield capable of changing the transparency of the windshield to be transparent in case where an authenticated user approaches the vehicle, and changing the transparency of the windshield to be non-transparent in case where an unauthenticated user approaches the vehicle.
On the other hand, the present disclosure may change the transparency of the windshield based on the satisfaction of various conditions as well as a speed of the vehicle and whether or not a user approaches the vehicle.
The processor 870 may adjust the transparency of the windshield 810 based on the surrounding brightness of the vehicle 100 sensed through the sensing unit 860 .
For example, as illustrated in FIG. 13A , when the surrounding brightness of the vehicle is brighter than a reference brightness, the processor 870 may set the transparency of the windshield to be a first transparency (for example, light transmittance of 40%).
For another example, as illustrated in FIG. 13B , when the surrounding brightness of the vehicle is darker than a reference brightness, the processor 870 may set the transparency of the windshield to be a second transparency (for example, light transmittance of 100%) that is more transparent than the first transparency.
In addition, the processor 870 may adjust the transparency of the windshield 810 based on the surrounding environment of the vehicle sensed through the sensing unit 860 .
For example, the processor 870 may set the transparency of the windshield to be different according to the sensed surrounding environment (for example, humidity, fog, snow, rain, etc.) of the vehicle.
On the other hand, when the vehicle 100 is being stopped (or in a parking state) the processor 870 may control the transparency of at least one of a plurality of windshields 810 to be different from that of the remaining windshields based on whether or not a preset object exists within a predetermined distance from the vehicle 100 .
For example, referring to FIG. 14 , when the vehicle 100 is being stopped, the processor 870 may sense an object existing within a predetermined distance from the vehicle 100 .
The processor 870 may determine whether or not an object sensed through the sensing unit 860 is a preset object.
Here, the preset object may be a previously set object to vary the transparency of the windshield, and have various types. For an example, the preset object may be a wall (W) as illustrated in FIG. 14 or another vehicle though not shown in the drawing. Furthermore, the preset object may include all objects obstructing the user's passage between the vehicle 100 and the object.
When the sensed object is a preset object, and the preset object (W) exists within a predetermined distance from the vehicle 100 , the processor 870 may control the transparency of at least one windshield 1400 a of a plurality of windshields to be different from that of the remaining windshield.
For an example, the at least one windshield 1400 a of the plurality of windshields may be a windshield disposed at a side in which the preset (W) exists.
The processor 870 may set the transparency of the windshield 810 a disposed at a side in which the preset object (W) exists among the plurality of windshields to a first transparency (for example, light transmittance of 100%), and set the transparency of the remaining windshields to a second transparency (for example, light transmittance of 40%) different from the first transparency.
Through the foregoing configuration, it may be possible to provide a vehicle control device capable of allowing the transparency of a windshield disposed at a side in which passers-by are rare to be transparent and the transparency of a windshield at a side in which passers-by are frequent to be non-transparent.
On the other hand, the windshield 810 associated with the present disclosure may be formed to allow changing the transparency of a partial region of the entire region.
For example, as illustrated in FIG. 15 , the windshield 810 of the present disclosure may be set to allow partially changing the transparency on one windshield.
For an example, the processor 870 may vary only the transparency of a partial region 1500 a on the entire region of the windshield.
The processor 870 may partially vary the transparency of the windshield based on a position at which a user gets in the vehicle 100 , for example.
For example, as illustrated in FIG. 15 , the processor 870 may set the transparency of only a partial region 1500 a in which a driver gets in the vehicle on a front windshield to a first transparency (for example, light transmittance of 100%), and set the transparency of the remaining portion to a second transparency (for example, light transmittance of 70%).
In addition, the present disclosure may vary the transparency of a partial region of the windshield based on various conditions.
For example, as illustrated in FIG. 16A , when an authenticated user (P 1 ) approaching the vehicle 100 is sensed through the sensing unit 860 , the processor 870 may change the transparency of a partial region 1600 a of the windshield located in a direction in which the authenticated user (P 1 ) approaches.
On the other hand, as illustrated in FIG. 16B , when an unauthenticated user (P 2 ) approaching the vehicle is sensed, the sensing unit 860 may maintain the transparency of the windshield with no change.
On the other hand, as illustrated in FIG. 16C , when a touch is applied to the windshield, the processor 870 may change the transparency of a predetermined-sized region 1600 b around a position to which the touch is applied.
The region 1600 b may be a circular shape having a predetermined radius from a position to which the touch is applied or a region including a position to which the touch is applied.
The configuration of FIG. 16 may be carried out when an authenticated user performs an operation. For example, when an authenticated user applies a touch to one position of the windshield 810 , the processor 870 may change the transparency of a predetermined-sized region 1600 b around the one position.
While the touch is maintained on the windshield, the processor 870 may change the transparency of the region 1600 b . The processor 870 may restore the changed transparency on the region 1600 b based on the touch being released or restore the changed transparency on the region 1600 b after the passage of a predetermined period of time subsequent to releasing the touch.
On the other hand, the processor 870 may perform various functions based on a user gesture applied to the windshield 810 .
For example, when a tap gesture is applied to the windshield 810 with a first transparency (for example, light transmittance of 40%) as illustrated in FIG. 17A , the processor 870 may change the first transparency to a second transparency (for example, light transmittance of 100%) as illustrated in FIG. 17B .
Then, when a new tap gesture is applied to the windshield with the second transparency as illustrated in FIG. 17C , the processor 870 may lower or raise the windshield.
For example, when the new tap gesture is applied in a state that the windshield is closed, the processor 870 may lower the windshield. Otherwise, when the new tap gesture is applied in a state that the windshield is open, the processor 870 may raise the windshield.
Furthermore, the processor 870 may lower the windshield when the new tap gesture is applied in a state that the windshield is lowered by a predetermined distance.
On the other hand, the processor 870 may determine whether to change the transparency of the windshield, or lower or raise the windshield according to the type of a gesture applied to the windshield.
For example, when a first type of tap gesture (for example, short tap) is applied to the windshield, the processor 870 may change the transparency.
For another example, when a second type of tap gesture (for example, double tap) is applied to the windshield, the processor 870 may lower the windshield without changing the transparency.
For still another example, when a type of tap gesture (for example, long tap) is applied to the windshield, the processor 870 may raise the windshield without changing the transparency.
The processor 870 may determine whether to adjust the transparency of the windshield, or lower the windshield or raise the windshield based on at least one of a position to which the a gesture is applied and an intensity of the gesture as well as a type of the gesture applied to the windshield.
Furthermore, when the transparency of the windshield is changed based on the tap gesture, the processor 870 may change the transparency of the entire windshield 810 to which the tap gesture is applied or change only the transparency on a predetermined-sized region around a position to which the tap gesture is applied.
The characteristics of FIG. 17 may be carried out when an operation is performed by an authenticated user. However, the present disclosure may not be necessarily limited to this.
On the other hand, the processor 870 may adjust the transparency of the windshield 810 to be more transparent as a distance between a user (authenticated user (P 1 )) and the vehicle 100 decreases.
For example, as illustrated in FIG. 18 , when a distance between a user (authenticated user (P 1 )) and the vehicle 100 is d 1 , the processor 870 may set the windshield 810 to a first transparency (for example, light transmittance of 40%).
On the other hand, when a distance between the user (authenticated user (P 1 )) and the vehicle 100 is d 2 which is shorter than the d 1 , the processor 870 may set the windshield 810 to a second transparency (for example, light transmittance of 70%) that is more transparent than the first transparency.
The transparency of the windshield 810 may be more transparent as a distance between the user and the vehicle decreases.
On the other hand, when a preset user (P 4 ) (for example, police officer, civil servant, firefighter, etc.) is sensed within a predetermined distance (d 3 ) from the vehicle 100 , the processor 870 may change (set) the transparency of the windshield to be transparent (for example, light transmittance of 100%).
Through the foregoing configuration, it may be possible to provide a vehicle control device capable of controlling the transparency of the windshield in various ways based on the satisfaction of a preset condition.
On the other hand, the present disclosure may emit light or display information on the windshield as well as control the transparency of the windshield, thereby providing various user experiences (UXs) to a user.
FIGS. 19, 20, 21, 22, 23 and 24 are conceptual views for explaining various embodiments using a windshield according to an embodiment of the present disclosure.
The windshield associated with the present disclosure may emit light. For example, the windshield 810 may increase display brightness (screen brightness) to emit light to an outside of the vehicle.
For another example, a light source capable of emitting light to an outside of the vehicle may exist on at least part of the windshield.
When information associated with the vehicle sensed through the sensing unit 860 satisfies a preset condition, the processor 870 may control the windshield to allow at least one of a plurality of windshields to emit light.
For example, as illustrated in FIG. 19 , the processor 870 may allow at least one of the windshields 810 to emit light based on that a shock above a predetermined amount is applied to an outside of the vehicle, or an authenticated user approaches within a predetermined distance from the vehicle, or an authenticated user touches the vehicle 100 .
Here, the processor 870 may emit light on all the plurality of windshields, and emit light on only at least one windshield disposed at a side in which an unauthenticated user is located.
Through the foregoing configuration, the present disclosure may provide a user interface capable of sending a warning through the windshield.
Furthermore, when another vehicle 2000 performing parking or passing ahead is sensed as illustrated in FIG. 20 , the processor 870 may emit light on a windshield 2010 disposed in the direction of performing parking or passing ahead.
Through the foregoing configuration, the present disclosure may provide a windshield capable of increasing an amount of light in a space located in the direction of performing parking or passing ahead to prevent an accident due to another vehicle.
On the other hand, when a distance to another vehicle sensed through the sensing unit 860 is less than a reference distance, the processor 870 may emit light on a windshield 2100 a disposed at a side of the another vehicle.
For example, as illustrated in FIG. 21 , when a distance to another oncoming vehicle 2000 is less than a reference distance in a state that the vehicle 100 is traveling, the processor 870 may emit light on the windshield 2100 a disposed at a side of the another vehicle.
On the other hand, as illustrated in FIG. 22 , the processor 870 may emit different colors of light on windshields. The processor 870 may determine the color of light emitted on a windshield based on the user's setting or information associated with a vehicle sensed through the sensing unit.
Through the foregoing configuration, the present disclosure may provide a windshield that can be modified in various ways according to circumstances or a user's preferences.
On the other hand, the present disclosure may display screen information on a windshield.
Here, screen information may include all types of information that can be displayed on a display device. For example, the screen information may include various types of information such as a text, an image, a video, an icon, a graphic object, a page, and the like.
The windshield 810 of the present disclosure is able to display screen information. Furthermore, the processor 870 may display different screen information on the windshield 810 based on information associated with the sensed vehicle.
For example, as illustrated in FIG. 23 , when another vehicle 200 approaches within a predetermined distance through the sensing unit 860 , the processor 870 may display first screen information 2300 (for example, warning message) on the windshield.
For another example, as illustrated in FIG. 24 , when connected to a smart key or an authenticated user's mobile terminal to enable communication, the processor 870 may display second screen information 2400 (for example, an icon indicating the current status of the vehicle) associated with the vehicle on the windshield 810 .
Through the foregoing configuration, the present disclosure may provide a user interface capable of displaying various information through the windshield.
According to an embodiment of the present disclosure, there are one or more following effects.
First, the present disclosure may have an effect capable of providing a new vehicle control method capable of varying the transparency of a windshield according to a speed of the vehicle.
Second, the present disclosure may provide a vehicle control device and a vehicle capable of varying the transparency of a windshield according to whether or not a user approaches the surrounding of the vehicle and an approaching user is an authenticated user, thereby having an effect capable of providing convenience to allow the authenticated user to more conveniently see an inside of the vehicle from an outside as well as enhancing security to disallow an unauthenticated user to see an inside thereof.
Third, the present disclosure may irradiate light or display screen information in addition to the transparency of the windshield based on information associated with the vehicle, thereby having an effect capable of effectively notifying a notice or notification information to nearby vehicles.
The effects of the present invention may not be limited to those effects, and other effects which have not been mentioned can be obviously understood by those skilled in the art from the appending claims.
The foregoing vehicle control device 800 may be included in the vehicle 100 .
Furthermore, the operation or control method of the foregoing vehicle control device 800 may be analogically applicable to the operation or control method of the vehicle 100 (or controller 170 ) in the same or similar manner.
For example, the control method of the vehicle 100 (or control method of the vehicle control device 800 ) may include sensing information associated with a vehicle through a sensing unit, and adjusting the transparency of a windshield provided in the vehicle based on that the sensed information satisfies a preset condition.
The above process may be carried out by the controller 170 provided in the vehicle 100 as well as by the vehicle control device 800 .
Furthermore, every function, configuration or control method executed by the vehicle control device 800 may be executed by the controller 170 provided in the vehicle 100 . In other words, every control method disclosed herein may be applicable to the control method of the vehicle, and also applicable to the control method of the control device.
The foregoing present invention may be implemented as codes readable by a computer on a medium written by the program. The computer-readable media may include all kinds of recording devices in which data readable by a computer system is stored. Examples of the computer-readable media may include ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage device, and the like, and also include a device implemented in the form of a carrier wave (for example, transmission via the Internet). In addition, the computer may include a processor or controller. Accordingly, the detailed description thereof should not be construed as restrictive in all aspects but considered as illustrative.
