The learning value information and the learning coefficient are created and registered in the menu structure database unit 4 at the time of learning coefficient setting processing or learning processing by the menu learning / structure construction unit 5 described later.
[0018]
For example, as shown in FIG. 2, the full menu information is composed of the first layer (main menu) in the highest layer to the fifth layer in the lowest layer. This full menu information is composed of process execution menu items for determining the execution of the process in the fifth layer, which is the lowest layer, and the first to fourth layers select the process execution menu items in the fifth layer. This is a menu item for selecting a process in the middle. The full menu is configured to display four menu items on one screen as operation menus on one screen. Note that the menu item for execution of processing may be set as the lowest layer not only in the fifth layer but also in the second to fourth layers.
[0019]
Further, the change menu information is constructed by limiting the number of hierarchies with respect to the full menu, and the menu learning / structure construction unit 5 determines and stores the process execution menu items and the process selection menu items in each hierarchy. Is done.
[0020]
Further, the menu structure database unit 4 stores menu item display data for displaying each menu item corresponding to each menu item. The full menu information is stored with the menu learning / structure construction unit 5 prohibited from changing the menu items.
[0021]
The menu learning / structure construction unit 5 uses various information registered in the menu structure database unit 4, and based on the driving load estimated by the driving load estimation unit 2 and the operation content of the operation unit 3, the following Do various processing.
[0022]
[Processing contents of menu learning / structure construction unit 5]
"Operation menu display process"
The menu learning / structure construction unit 5 inputs the driving load information from the driving load estimation unit 2 and the operation input signal from the operation unit 3 and displays them on the monitor unit 1 with reference to the full menu information and the changed menu information. The menu item display data to be read is read from the menu structure database unit 4 and displayed as a menu.
[0023]
When the operation learning unit 5 is operated and an operation input signal is input in a state where an operation menu including a plurality of process selection menu items is displayed, the menu learning / structure construction unit 5 selects the selected menu item. The operation menu set in the lower layer is displayed with reference to the transition relation information. The menu learning / structure construction unit 5 executes the selected process when an operation input signal from the operation unit 3 is input in a state where an operation menu including a plurality of process execution menu items is displayed. By referring to the function information corresponding to the menu item, a process execution command corresponding to the function information is output to the navigation / audio processing unit 6 or the like to execute the process.
[0024]
Specifically, the menu learning / structure construction unit 5 has “navigation”, “phone”, “email”, “audio” set as the menu items of the main menu in the first hierarchy, and “navigation”. The menu item display data to be displayed in the menu display area 12 in one screen is read out and displayed, such as button display of “”, button display of “telephone”, button display of “E-mail”, and button display of “audio”. Then, for example, when the “phone” process selection menu item indicated by the hatched portion in FIG. 2 is selected, an operation menu including four process selection menu items in the second hierarchy is displayed, and the second hierarchy is displayed. When the menu item for process selection of “call” is selected in, an operation menu composed of four menu items for process selection in the third hierarchy is displayed, and the process of “address book” is selected in the third hierarchy. When the menu item for work is selected, an operation menu consisting of four menu items for process selection in the fourth hierarchy is displayed. When the menu item for process selection of “work” is selected in the fourth hierarchy, An operation menu including four process execution menu items in the fifth layer is displayed. When the menu learning / structure construction unit 5 recognizes that the “office” process execution menu item has been selected in the fifth layer, an instruction to execute the process of calling the office is sent to the external communication device. send.
[0025]
Further, the menu learning / structure construction unit 5 performs display control of the changed menu information instead of the full menu information indicating the full menu based on the driving load estimated by the driving load estimation unit 2. In this example, for example, full menu information can be used when the vehicle is stopped, and only changed menu information can be used when traveling.
[0026]
"Menu item selection process"
The menu learning / structure construction unit 5 performs a menu item selection process for selecting four menu items to be presented in each layer constituting the change menu. That is, the menu learning / structure construction unit 5 limits the number of levels of the changed menu information in comparison with the full menu according to the driving load, and the menu items to be displayed in each limited level are based on the learning value information. select. At this time, the menu learning / structure construction unit 5 selects a process selection menu item that is frequently used from the learned value information, creates an integrated menu item that integrates a plurality of different functions, and further uses the usage frequency. Subdivide high processing selection menu items into higher layers.
[0027]
Thereby, the menu learning / structure construction unit 5 changes the full menu shown in FIG. 2 to a change menu as shown in FIG. 3 or FIG. The change menu information shown in FIG. 3 and FIG. 4 is limited to the third hierarchy by the menu learning / structure construction unit 5 while the full menu exists up to the fifth hierarchy because there is a driving load during traveling. ing.
[0028]
Specifically, the change menu information shown in FIG. 3 and FIG. 4 includes a menu item 11 for selecting a process for selecting an audio function as the first layer, and a function for selecting different types of functions such as telephone and e-mail. Integrated menu item 12 for process selection, navigation / audio processing unit 6 for displaying a navigation function destination in process / selection menu item 13 for displaying a navigation function destination in navigation / audio processing unit 6 The menu item for presenting the process selection menu item 14 is selected. Here, if the use frequency of the process selection menu item 11, the process selection integrated menu item 12, the process selection menu item 13 and the process selection menu item 14 is high from the learning value information, the menu learning / structure construction unit 5 The determined menu item.
[0029]
Further, the process selection menu item 13 and the process selection menu item 14 include a process selection menu item for causing the full menu of FIG. 2 to select a navigation function in the first hierarchy. The menu items are subdivided to change the hierarchy from the second hierarchy to the first hierarchy.
[0030]
Further, in FIG. 3 and FIG. 4, the menu learning / structure construction unit 5 sets an integrated menu item 12 for process selection. The integrated menu item 12 for process selection is a menu item that does not exist in the full menu of FIG. 2 and is created by the menu learning / structure construction unit 5. In the process selection integrated menu item 12, as shown in FIG. 3, menu items for selecting an e-mail function and a telephone function are set in the lower layer as transition relation information regarding the change menu information.
[0031]
Specifically, in the lower layer (second layer) of the process selection integrated menu item 12, the process selection menu item 21 set in the lower layer of the process selection menu item for selecting the telephone function in the full menu. , 22, process selection menu items 23 and 24 set in a lower layer of the process selection menu item for selecting the e-mail function in the full menu are set. It is registered in the menu structure database unit 4 by the transition relation information that these menu items 21 to 24 for process selection are located in a lower layer of the integrated menu item 12 for process selection. Further, the process selection menu items 21 to 24 are the menu item for process selection for selecting the navigation function in FIG. 2 and 4 in the lower layer (second hierarchy) of the menu item for process selection for selecting the telephone function. Of the more than one menu item, the menu item is determined by the menu learning / structure construction unit 5 when the use frequency is high from the learning value information.
[0032]
Furthermore, in the lower layer (third layer) of the menu item 22 for process selection, menu items 31 to 34 for process execution set in the lower layer of the menu item for process selection “call” in the full menu. Is set. It is registered in the menu structure database unit 4 by the transition relation information that these menu items 31 to 34 for process execution are located in the lower layer of the menu item 22 for process selection. Further, the process execution menu items 31 to 34 are four or more process execution menu items in a lower layer (third to fifth layers) of the process selection menu item “call” in FIG. Among these, the menu item for process execution is determined by the menu learning / structure construction unit 5 when the use frequency is high from the learning value information.
[0033]
Another specific example of the process selection integrated menu item 12 is a process selection menu for selecting a telephone function as the second layer based on the learning value information of each menu item, as shown in FIG. Items 41 to 42 and a process selection menu item 44 for selecting an e-mail function are registered, and process execution menu items 51 to 54 are set as transition relation information as the third hierarchy for the process selection menu item 42. May be.
[0034]
Further, the process selection menu item and the process execution menu item may be detected in the operation history information divided into holidays or time zones and stored in the menu structure database unit 4. Thereby, when performing the operation menu display process, the menu learning / structure construction unit 5 changed the process execution menu item and the process selection menu item to be displayed with priority according to weekdays, holidays, or time zones. It can be changed menu information.
[0035]
"Learning process"
Further, the menu learning / structure construction unit 5 performs a learning process in which the learning value information of each menu item is changed by weighting (learning coefficient) in accordance with the operation of the operation unit 3. Here, the menu learning / structure construction unit 5 updates the operation history information indicating the operation history for each menu item in response to detecting the operation of the operation unit 3 in a state where various menu items are displayed. . The menu learning / structure construction unit 5 adds up the operation history information of each menu item in the lower layer set in the transition relation information for the process selection menu item, and uses the total value as a learning coefficient. To create learning value information divided by On the other hand, the menu learning / structure construction unit 5 uses the operation history information indicating the selected number of operations as learning value information for the menu item for process execution.
[0036]
Specifically, as shown in FIG. 5, a process selection menu item (special A, for example, “audio”) and a process selection menu item (special B, for example, “E-mail”) included in the full menu information, processing Integrated menu items for selection exist in the same hierarchy, menu items A to D at the lower layer of the menu item for processing selection (specialized A), and menu items E to H at the lower layer of the menu item for selecting processing (specialized B) Suppose that menu items A, B, E, and F are registered in the lower layer of the integrated menu item for process selection. Note that each menu item shown in FIG. 5 is included in the change menu information.
[0037]
In such a state, for example, as shown in FIG. 6, the menu item A is 5 times, the menu item B is 4 times, and the menu item C is between the time the vehicle display device is turned on and the time it is turned off. Menu item D once, menu item E five times, menu item F four times, menu item G once, menu item H once selected, menu learning / structure construction from operation history information When the unit 5 recognizes, the menu learning / structure construction unit 5 adds the coefficient information “11” to the total value “11” of the menu items A to D set in the lower layer of the process selection menu item (specialty A). The value “11” multiplied by “1” is used as learning value information for the menu item for processing selection (specialized A), and similarly, the learning value information for the menu item for selecting processing (specialized B) is set to “11”. In addition, the menu learning / structure construction unit 5 multiplies the total value “18” of the menu items A, B, E, and F set in the lower layer of the process selection integrated menu item by the coefficient information “0.8”. The value “14.4” is used as learning value information for the menu item for process selection integration.
[0038]
Thereby, in the menu learning / structure construction unit 5, the process selection menu item for specialty A, the process selection menu item for specialty B, and the integrated menu item for process selection exist in the same hierarchy (for example, the first hierarchy). The display unit is controlled to display the integrated menu item for process selection having the highest learned value information as the menu item having the highest use frequency.
[0039]
Further, as shown in FIG. 6, when there is operation history information that the menu item A is selected 5 times, the menu item B is selected 4 times, and the menu items C to H are selected 0 times, the menu item for process selection ( The learning value information for the specialty A) is “9”, the learning value information for the process selection menu item (specialty B) is “0”, and the learning value information for the integrated menu item for processing selection is “7.2”. " Therefore, in such a case, the menu item for process selection (specialized A) is assumed to be most frequently used.
[0040]
Further, as shown in FIG. 6, the operation that the menu item A is selected 5 times, the menu item B is 4 times, the menu item C is 2 times, the menu item D is 1 time, and the menu items E to H are selected 4 times. If there is history information, the learning value information for the menu item for processing selection (specialty A) is “12”, and the learning value information for the menu item for processing selection (specialty B) is “16”. The learned value information for the integrated menu item for use is “13.6”. Therefore, in such a case, it is assumed that the menu item for process selection (specialized B) is most frequently used.
[0041]
Further, as shown in FIG. 6, when there is operation history information indicating that menu items A to H are all selected four times, a process selection menu item (specialized A) and a process selection menu item (specialized B) The learning value information for “16” is “16”, and the learning value information for the integrated menu item for process selection is “12.8”. Therefore, in such a case, it is assumed that the process selection menu item (specialized A) or the process selection menu item (specialized B) is most frequently used.
[0042]
"Learning coefficient setting process"
The menu learning / structure construction unit 5 performs a learning coefficient setting process for setting a learning coefficient to be used when performing the above-described learning process and registering it in the menu structure database unit 4.
[0043]
First, the process for setting the learning coefficient according to the relationship between the menu items included in the full menu information and the menu items included in the change menu information and the integrated menu items for process selection will be described.
[0044]
For example, FIG. 7 shows the first and second hierarchies of the change menu information (first to second hierarchies), and FIG. 8 shows the second hierarchy learning value information and the first hierarchy learning value information. The menu learning / structure construction unit 5 sets the learning coefficient for the process selection menu items (items 1 to 3) to “1”, and the menu selection for the process selection menu items (item 1-1, item 1-2). The learning coefficient is set to “1.1”, and the learning coefficient for the process selection integrated menu item A is set to “0.8”.
[0045]
This is because the process selection menu item in the lower layer of the process selection menu item (item 1) and the process selection menu item (item 2) includes an integrated menu item for process selection and different processes in the full menu. Menu items (specialized A, B, E, specialized a, b, e) located in the lower layer of the menu item for selection are registered, and further, a menu item for selecting a process (item 3) and an integrated menu for selecting a process In item A, menu items (specialized f, h, m, q, specialized A, B, a, b) located in the lower layer of different menu items for processing selection in the full menu are registered. The menu items for processing selection (items 1-1 and 1-2) are menu items (special A, B, C, D, special E, and subordinate to the same processing selection menu item in the full menu). , Due to the fact that G) has been registered.
[0046]
Further, for example, FIG. 9 shows the second hierarchy and the third hierarchy of the change menu information (second hierarchy to third hierarchy), and FIG. 8 shows the learning value information of the third hierarchy and the learning value information of the second hierarchy. In this case, the menu learning / structure construction unit 5 sets the learning coefficient for the process selection menu item (specialized A, B, C, D) to “1”, and sets it as an integrated menu item for process selection (integration 1, 2). The learning coefficient is set to “0.8”.
[0047]
In the integrated menu item for process selection, menu items located in lower layers of different menu items for process selection in the full menu are registered, whereas menu items for process selection (items 1-1 and 1-1) are registered. In 1-2), menu items (special A, B, C, D, special E, F, G) located in the lower layer of the same process selection menu item in the full menu are registered.
[0048]
Next, as another learning coefficient setting process by the menu learning / structure construction unit 5, a case where the learning coefficient of each menu item is changed with time will be described.
[0049]
Here, FIG. 11 shows the change menu information, and FIG. 12 shows changes in the operation history information and the learning value information of the menu items of time “1” to “4” corresponding to the change menu information. 13 shows the time change of the learning coefficient. As shown in FIG. 13, in the menu learning / structure construction unit 5, for example, when no menu item is selected for a certain period of time, the learning coefficient is reduced by, for example, “0.8” units.
[0050]
When such processing is performed, the menu learning / structure construction unit 5 multiplies the operation history of the oldest time “1” to the operation history of the latest time “4” in FIG. Let it be a history.
[0051]
That is, as shown in FIG. 12, the operation history information for the operation at time “1” includes, for example, menu item A five times, menu item B four times, menu item C once, menu item D is 1 time, menu item E is 2 times, menu item F is 5 times, menu item G is 1 time, menu item H is selected 3 times and the learning value of the menu item for processing selection (specialized A, specialized B) The value of the information is “11”, and the value of the process selection integrated menu item is “13.6”. Then, at the next time “2”, when the menu item C is operated once, the menu item D is operated twice, the menu item E is operated three times, and the menu item E is operated once, the menu learning / structure construction unit As shown in FIG. 13, the operation history information value at time “1” is multiplied by a learning coefficient of 0.8 as shown in FIG. As a result, the menu learning / structure construction unit 5 sets the operation history information values of the menu items A, B, F, and G that are not operated at time “2” to “4”, “3.2”, “ 4 ”and“ 3.4 ”, and the values of the operation history information of the menu items C, D, E, and H are“ 1.8 ”,“ 2.8 ”,“ 4.6 ”, and“ 3. 4 ”. The value of the learning value information of the menu item for processing selection (specialty A) is “11.8”, the value of the learning value information of the menu item for processing selection (specialty A) is “12.8”, and integration for processing selection is performed. The value of the learning value information of the menu item is “11.2”.
[0052]
When the menu items B, E, and G are each operated twice at time “3”, and when the menu items D and G are respectively operated twice and twice at time “4”, the time elapses. Accordingly, the operation history information and the learning value information as shown in FIG. 12 are obtained by performing the same calculation with reference to the data of FIG. Thereby, the menu learning / structure construction unit 5 suppresses the learning value information from becoming too high by decreasing the learning coefficient with time.
[0053]
The menu learning / structure construction unit 5 not only changes the learning coefficient related to the changed menu item according to the relationship of the full menu information and the elapsed time as described above, but also from the driving load estimation unit 2. The learning coefficient may be changed according to the driving load. In this case, when the menu learning / structure construction unit 5 determines that the vehicle is traveling from the driving load, the learning coefficient is set high to facilitate learning, and when it is determined that the vehicle is stopped from the driving load. Makes learning difficult by setting the learning coefficient lower than when driving.
[0054]
"Learning process, learning coefficient setting process"
Next, a processing procedure for performing learning processing and learning coefficient setting processing by the menu learning / structure construction unit 5 having the above-described functions will be described with reference to the flowchart of FIG. In the description of this processing procedure, a case will be described in which the third hierarchy of the change menu information including the first hierarchy to the third hierarchy is displayed on the monitor unit 1.
[0055]
First, in the state where the operation menu including, for example, four process execution menu items is displayed on the monitor unit 1, any one of the processes is executed in response to the operation unit 3 being operated by the driver (driver). When the menu learning / structure construction unit 5 recognizes the selection of the menu item for use (step S1), the process proceeds to step S2.
[0056]
In step S <b> 2, the menu learning / structure construction unit 5 determines whether or not the same menu item (function) for process execution is selected unexpectedly. That is, the menu learning / structure construction unit 5 determines whether or not the ratio and interval at which a certain menu item for executing the same process with respect to the driving time (starting time of the vehicle display device) is equal to or greater than a predetermined threshold. By doing so, it is determined whether or not a certain menu item for process execution has been selected several times in a certain time.
[0057]
Then, the menu learning / structure construction unit 5 determines that it is not a sudden operation when it is determined that the ratio or interval at which a certain menu item for executing the same process is selected is not equal to or greater than a predetermined threshold, and the process proceeds to step S3. On the other hand, if it is determined that the ratio or interval at which a certain menu item for executing the same process is selected is equal to or greater than a predetermined threshold, it is determined that the operation is a sudden operation, and the process proceeds to step S4.
[0058]
In step S3 and step S4, the menu learning / structure construction unit 5 executes the learning coefficient setting process as described above.
[0059]
In step S3, the menu learning / structure construction unit 5 sets the value of the learning coefficient related to the processing execution menu item operated in step S1 to a value that is not unexpected and stores it in the menu structure database unit 4. Then, the process proceeds to step S5. At this time, the menu learning / structure construction unit 5 sets the reference value of the learning coefficient according to the determination that it is not sudden in step S <b> 2 to “1”, and from the driving load from the driving load estimation unit 2. When it is determined that the vehicle is traveling, the learning coefficient is changed from the reference value “1” to “1.2”, while when it is determined that the vehicle is stopped, the learning coefficient is set to the reference value “1”. Leave.
[0060]
On the other hand, in step S4, the menu learning / structure construction unit 5 sets the value of the learning coefficient related to the processing execution menu item operated in step S1 to a value for sudden occurrence, and the menu structure database unit 4 And proceed to step S5. At this time, the menu learning / structure construction unit 5 sets the reference value of the learning coefficient according to the determination that it is not sudden in step S2 to “0.8”, and the driving from the driving load estimation unit 2 When it is determined that the vehicle is running from the load, the learning coefficient is changed from the reference value “0.8” to “1”, while when it is determined that the vehicle is stopped, the learning coefficient is set to the reference value “0”. .8 ".
[0061]
In step S5, the menu learning / structure construction unit 5 modifies the operation history information of the menu item for processing execution selected in step S1 using the learning coefficient set in step S3 or step S4. A learning process stored in the menu structure database unit 4 is performed. Further, in this step S5, using the operation history information after the correction of the process execution menu item selected in step S1, the process selection for the second layer located in the upper layer of the process execution menu item is selected. The learning value information of the menu item is calculated, and the process proceeds to step S6.
[0062]
In step S5, the menu learning / structure construction unit 5 changes the learning coefficient based on the passage of time described above, and operates the process execution menu item and the process selection menu item that are not selected in step S1. The history information is changed, and a learning process for correcting the learning value information of each process selection menu item is also performed.
[0063]
In step S6, the menu learning / structure construction unit 5 determines whether or not the configuration of the operation menu including the second-level process selection menu item for which the learning value information is calculated in step S5 is changed. That is, in the menu learning / structure construction unit 5, among the menu items for process selection registered in the same second hierarchy as the process selection menu items for which the learning value information is calculated in step S5, the menu learning / structure construction unit 5 displays the second hierarchy. It is determined whether or not the configuration of the menu item for processing selection to be changed is changed.
[0064]
If the menu learning / structure construction unit 5 determines that the configuration of the operation menu in the second hierarchy is not changed, the menu learning / structure construction unit 5 determines that the configuration of the operation menu changes while proceeding to step S7 to end the learning process. In that case, the process proceeds to step S8.
[0065]
In step S8, the menu learning / structure construction unit 5 configures each of the operation menus in the first layer in response to the change of the process selection menu item that configures the operation menu in the second layer in step S6. The learning value information about the process selection menu item is corrected by calculating using the learning value information of the second-level process selection menu item after the change, and the process proceeds to step S9.
[0066]
In step S9, the menu learning / structure construction unit 5 determines whether or not the configuration of the first-level operation menu including the process selection menu item for which the learning value information has been calculated in step S8 is changed. That is, the menu learning / structure construction unit 5 performs the same determination as in step S5 for the first hierarchy.
[0067]
If the menu learning / structure construction unit 5 determines that the configuration of the operation menu in the first hierarchy is not changed, the menu learning / structure construction unit 5 determines that the configuration of the operation menu changes while proceeding to step S7 to end the learning process. In that case, the process proceeds to step S10.
[0068]
In step S10, the menu learning / structure construction unit 5 configures each of the operation menus in the first layer in response to the change of the process selection menu item that configures the operation menu in the first layer in step S9. The learning value information for the menu item for process selection is corrected by calculating using the operation history information of the menu item for process selection in the first hierarchy, the process proceeds to step S7, and the learning process ends.

[Effect of the embodiment]
As described above in detail, according to the vehicular display device according to the present embodiment, in addition to the full menu information, change menu information in which the number of layers is more limited than the full menu information is created, Depending on the situation, you can use any of the menu information to select a process, taking into consideration the special environment such as driving, and the number of times of selection is fixed, so for example when an operation menu is created according to the operation history Even so, the user's operation burden is not increased.
[0070]
In addition, according to the display device for a vehicle, based on the operation history information for each process selection menu item and the process selection menu item, the changed menu information is preferentially displayed so that the menu item having a higher frequency of selection is displayed. Therefore, the menu items frequently used by the user can be prioritized, and the operation burden on the user can be reduced.
[0071]
Furthermore, according to the vehicle display device, the operation history is detected by dividing it into weekdays, holidays, or time zones, and the menu items to be displayed with priority according to the weekdays, holidays, or time zones are changed. Even a user who uses different functions can reduce the operation burden.
[0072]
Furthermore, according to the vehicular display device, the change menu information is created by subdividing a frequently used process selection menu item into a higher layer process selection menu item. When the setting process and the display setting process are frequently used as compared with the processes of other navigation functions, the menu items related to the destination setting process and the display setting process can be displayed in the upper hierarchy.
[0073]
Furthermore, according to the vehicle display device, the change menu information is created by creating an integrated menu item for processing selection that integrates a plurality of different menu items, so the menu items to be displayed in one screen are limited. Even in this case, it is possible to select more functions than the limited number of menu items, and further reduce the operation burden on the user.
[0074]
Furthermore, according to the vehicle display device, a learning coefficient for changing the learning speed is set for each process selection menu item and process execution menu item, and the operation history for each menu item is changed based on the learning coefficient. Since the change menu information is created, the learning speed of each menu item can be changed corresponding to various situations.
[0075]
Furthermore, according to the vehicle display device, the learning speed of the menu item in the lower layer of the integrated menu item for processing selection is set to be higher than the learning speed of the menu item in the lower layer of the menu item for processing selection included in the full menu information. Since the learning coefficient is set so as to be delayed, the menu item for processing selection included in the full menu information can be displayed in preference to the integrated menu item for processing selection, and the integrated menu for processing selection unfamiliar to the user It is possible to prevent the items from being frequently displayed and increasing the operation burden on the user.
[0076]
Furthermore, according to the vehicular display device, the learning coefficient is set so that the learning speed becomes slower as the time elapses after each menu item is selected, so that frequently used menu items are displayed. It is possible to reduce the user's operation burden by increasing the probability of performing the operation.
[0077]
Furthermore, according to the vehicle display device, the learning coefficient is set so that the learning speed becomes faster as the driving load is higher. The operation burden can be reduced.
[0078]
The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it is possible to change.
