Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a wind control system according to an embodiment of the present invention.

First, referring to FIG. 1, the wind control system 10 in this embodiment controls wind in a vehicle interior, specifically controlling wind direction, wind speed, and air volume in the vehicle interior, but includes a vehicle. This is achieved through a combination of the open state of the window or sunroof (hereinafter, unified as a window).

That is, when information about the wind direction, wind speed, and air volume in the vehicle desired by the user is input, considering the various factors affecting the wind direction, wind speed, and air volume in the vehicle, the same or as similar a wind direction, wind speed, and air volume as possible can be realized. The degree of opening for each window or sunroof the vehicle contains will be determined.

More specifically, the wind control system 10 includes a database unit 100, a user input unit 200, a determination unit 300, a window opening unit 400, an additional adjustment unit 500 and a user output unit 600. Includes.

The database unit 100 is provided with information on factors affecting wind direction, wind speed, or air volume generated in the vehicle interior as the window of the vehicle is opened in advance to database it.

For example, information about the window of the vehicle, that is, the number of windows of the vehicle, the location of the window, the degree of opening of the window, and the like can be provided in advance and databased. In addition, information about the speed of the vehicle, that is, information about the speed of the current driving vehicle may be provided in advance and databased.

In this case, information about the window of the vehicle is provided through the window information input unit 110, and information about the speed of the vehicle is provided through the vehicle information input unit 120.

Furthermore, information about the wind inside the vehicle may also be provided in advance and databased.

In this case, information about the wind inside the vehicle is provided through the wind information input unit 130.

More specifically, the information on the wind inside the vehicle means information on the wind inside the vehicle generated by an air conditioning or air conditioning system such as an air conditioner or an air conditioner inside the vehicle, and this information is database through simulation, etc. Can be angry.

On the other hand, the information about the wind inside the vehicle is provided with substantially all the information on the window of the vehicle and the speed of the vehicle, and an air conditioning or air conditioning system such as an air conditioner or an air conditioner inside the vehicle is provided. By adding information about the wind in the vehicle generated by, it can be databased through simulation, etc., that is, it can be databased through simulation in consideration of all factors affecting wind in the vehicle.

In this case, the wind inside the vehicle is influenced by the external design of the vehicle because the wind provided from the outside also affects the degree of opening of the window, and is influenced by the interior design of the vehicle.

Accordingly, when it is databased through the simulation or the like, information on the external design or the internal design of the vehicle is additionally input, and information on the wind inside the vehicle can be simulated and databased.

As described above, the information on the wind in the vehicle is information stored in the database unit 100 through simulation or the like in advance, depending on the situation in which the wind is provided to the interior of the vehicle. It will include information about the wind direction, wind speed and wind speed inside the vehicle.

Thus, when the information about the wind inside the vehicle is stored as a database, the database unit 100 includes the information classification unit 140 to classify the information about the wind inside the vehicle.

More specifically, as described above, when information about the wind inside the vehicle is provided to the database unit 100, the provided information eventually includes wind direction, wind speed, and air volume information inside the vehicle. The wind direction, wind speed, and air volume information inside the vehicle will eventually change according to the number of windows of the vehicle, the degree of opening for each window, and each combination of the speed of the vehicle. Of course, in this case, the air conditioning or blowing system of the vehicle is also considered, and the number of windows in the vehicle, the degree of opening of each window, the speed of the vehicle, and the wind direction inside the vehicle according to each combination of the air conditioner or the blowing condition , Wind speed and air volume information can be variously classified.

For example, if the number of windows is 4, the degree of opening of the window is divided into 3 levels, the speed of the vehicle is divided into 10 levels, and the internal air conditioning or blowing state of the vehicle is further divided into 5 levels, the above The information classification unit 140 of the database unit 100 may classify wind direction, wind speed, and air volume information inside the vehicle for a total of 4,050 cases.

Thus, the database unit 100 may store and store the wind direction, wind speed, and air volume information in the vehicle for each of the 4,050 branches through simulation or wind tunnel experiment.

As described above, the database unit 100 considers factors affecting the wind direction, wind speed, and wind volume of the vehicle's interior, and, in each case, simulates or wind tunnel tests to determine the wind direction, wind speed, and wind volume of the vehicle's interior. Information about the database.

In the user input unit 200, information on wind direction, wind speed, and air volume inside the vehicle that the user needs is input by a user input.

In this case, information about the wind direction, wind speed, and air volume input by the user may be input by a user's direct input through a separate input display (not shown).

However, the wind direction, wind speed, and air volume directly input by the user's selection may differ from the wind direction, wind speed, and air volume that are actually databased in the database unit 100.

Accordingly, the determination unit 300 selects information identical or similar to the information input by the user's selection from the database unit 100.

That is, the determination unit 300 first determines whether or not the same information as the information input by the user's selection exists in the wind direction, wind speed, and air volume information classified and stored in the database unit 100.

Thus, if the same information exists, the determination unit 300 selects the information, and when the same information does not exist, the information most similar to the information input by the user's selection is selected. .

In this case, the determination unit 300 includes the weight calculation unit 310 and the similarity calculation unit 320, and selects the information most similar to the information input by the user's selection.

More specifically, when the information input by the user's selection is different from the wind direction, wind speed, and air volume information classified in the database unit 100, the weight calculator 310 selects the most similar information, the wind direction, The most similar information is selected by adding a weight to the wind speed or air volume.

That is, the wind direction, wind speed, and wind quantity stored in the database unit 100 and the wind direction, wind speed, and wind quantity according to the user's selection include different individual elements. If all values are not the same, the most similar information is selected. Standards are required.

Therefore, if the values derived by multiplying each of the wind direction, wind speed, and air volume by first, second, and third weights are compared with each other, the most similar information can be selected very easily.

In this case, the first, second, and third weights each have a value of 0% or more and 100% or less, and the sum of the first, second, and third weights must be 100%.

For example, a first weight of 40% may be assigned to the wind direction, a weight of 40% may be assigned to the wind speed, and a weight of 20% may be assigned to the wind volume. Thus, the values derived by assigning the first to third weights to the information on the wind direction, wind speed, and air volume stored in the database unit 100 and stored, and information on the wind direction, wind speed, and air volume input by the user In the above, the values derived by applying the first to third weights are compared with each other to select information on wind direction, wind speed, and air volume at the most similar values.

Of course, when comparing the weight calculation results, a plurality of cases may be generated that are derived with the same value, and in this case, the wind direction, wind speed, and air volume information determined to be the most suitable may be selected.

Alternatively, through the similarity calculating unit 320, the information most similar to the information input by the user's selection may be selected.

That is, the similarity calculating unit 320 applies a similarity function to select the most similar information when the information input by the user's selection is different from the wind direction, wind speed, and air volume information classified in the database unit 100. do.

In this case, the similarity function applied by the similarity calculating unit 320 includes a similarity function for wind direction and a similarity function for wind speed. In this case, the similarity function for the air volume may also be considered, but the similarity to the air volume may be calculated in the same way as the similarity function for the wind speed, and thus redundant description will be omitted.

Is located in the denominator of a fraction, so if the value is 0, replace it with an infinite number to avoid an undefined problem.

That is, if the wind stored in the database unit 100 is referred to as a first wind, and the wind selected by the user is referred to as a second wind, the wind direction of the first wind and the wind direction of the second wind are the above equation (1). The similarity can be determined through, and the wind speed in the first direction and the wind speed in the second wind can be determined through the equation (2).

Thus, the most similar wind can be selected based on the similarity calculation result for the wind direction and wind speed of the first wind and the second wind (the air volume can be calculated in the same way), through which the same information as the information input by the user Even if it does not exist in the database unit 100, it is possible to select the most similar wind direction, wind speed, and air volume.

As described above, when information on the wind direction, wind speed, and air volume of the wind inside the vehicle is selected by the determination unit 300, the window opening 400 is the speed of the current vehicle, and furthermore, the air of the current vehicle. Based on the condition of conditioning or blowing, the window is opened based on the degree of opening of the window for deriving the wind direction, wind speed, and air volume.

Thus, based on the current state of the vehicle, the window may be opened so that the wind equal to or close to the wind selected by the user blows inside the vehicle.

Meanwhile, the additional adjustment unit 500 adjusts an additional window opening amount based on the degree of opening of the window opened by the window opening 400.

That is, if other conditions, i.e., the number of windows, the air conditioner or the air-conditioning condition inside the vehicle are constant, as the speed of the vehicle changes, the wind that is the same as or similar to the wind selected by the user is blown inside the vehicle. To maintain, the degree of opening of the window must be varied. Therefore, the window opening unit 400 adjusts the degree of opening of the window in order to maintain information on the wind direction, wind speed, and air volume of the selected wind in consideration of the speed of the vehicle.

The user output unit 600 displays and provides information on the wind direction, wind speed, and air volume inside the current vehicle to the user. In FIG. 1, although the user input unit 200 and the user output unit 600 are separately shown, a method of implementing the present invention is a screen display device having functions of the user input unit 200 and the user output unit 600. You can do

When the user input unit 200 initially receives information about the wind direction, wind speed, and air volume, the information on the wind direction, wind speed, and air volume that can be implemented in the current situation is emphasized in preparation for information on the wind direction, wind speed, and air volume that cannot be implemented. You can.

Further, the user output unit 600, in addition to simply providing information about the current wind direction, wind speed and air volume, based on the information selected by the determination unit 300, the vehicle including the speed of the vehicle In consideration of the current state, information on the wind direction, wind speed, and air volume that can be implemented may be additionally provided.

That is, when the same or the most similar wind direction, wind speed, and air volume are selected by the determination unit 300 according to the user's input or selection, in addition to providing corresponding information, the selected option is provided to provide various options to the user. Within the range similar to the information, information on wind direction, wind speed, and air volume that can be implemented inside the vehicle is additionally provided. Thus, the user can additionally select the wind direction, wind speed, and air volume based on the provided information, thereby increasing the user's choice.

2 is a flowchart illustrating a wind control method using the wind control system of FIG. 1. 3 is a flowchart illustrating the wind control method of FIG. 2 in more detail.

2 and 3, in the wind control method using the wind control system 10 according to the present embodiment, the method of the wind control, that is, the steps will be mainly described, and through the wind control system 10 previously Contents that overlap with the descriptions are omitted.

That is, in the wind control method, first, information about the window of the vehicle, information about the wind inside the vehicle, and information about the speed of the vehicle are stored in the database unit 100 (step S10).

More specifically, through the wind information input unit 130, information about the wind inside the vehicle is provided and stored in advance (step S11), and in this case, FIG. 1 shows the properties or contents of the wind information provided. As described with reference.

In addition, through the window information input unit 110, information on the number of windows in the vehicle and the degree of opening for each window is provided in advance and stored in the database unit 100 (step S12).

In addition, information about the speed of the vehicle is provided in advance through the vehicle information input unit 120 and stored in the database unit 100 (step S13).

Furthermore, it has already been described that the database unit 100 may additionally input information about the external design or internal design of the vehicle.

Thus, in the information classification unit 140 of the database unit 100, the number of windows provided, the degree of opening for each window, the speed of the vehicle, and furthermore, information about air conditioning or blowing in the interior of the vehicle On the basis of this, for each combination of the corresponding information, information on the wind direction, wind speed and air volume inside the vehicle is classified (step S14).

Thereafter, the user inputs information on the wind direction, wind speed, and air volume inside the vehicle that the user needs through the user input unit 200 (step S20).

Thereafter, the determination unit 300 compares the information classified and stored in the database unit 100 with the information input by the user, and stores the same information or the most similar information as the input information. Select from the information (step S30).

Thus, a window is opened based on the selected information (step S40). However, in this case, it is assumed that the opening of the window is influenced only by the factor of opening the window, the factors affecting the wind direction, wind speed, and air volume of the interior of the vehicle. That is, as described above, the wind inside the vehicle is variable depending on the speed of the vehicle, the number of windows, the condition of the air conditioning or blowing inside the vehicle, the degree of opening of the window, etc. It is assumed that only the degree of opening changes.

More specifically, the determination unit 300 determines whether information identical to the information input by the user exists in the information stored in the database unit 100 (step S31).

Thus, if it is determined that the same information exists, when the other states of the vehicle remain the same, that is, the speed of the vehicle remains the same, the air conditioning or air conditioning by the air conditioner or air conditioner inside the vehicle remains the same. If it is the case, etc., the window of the vehicle is opened in the same manner as the window opening degree in the same information stored in the database unit 100 (step S41).

Alternatively, in the determination unit 300, if the same information as the information input by the user does not exist in the database unit 100 (step S31), the weight is considered (step S32), or the similarity function By applying (step S33), the most similar information is selected among the information existing in the database unit 100.

Thus, based on the most similar information, similarly, assuming that other factors affecting the wind inside the vehicle are constant, the window of the vehicle is opened (step S42).

In this case, in the weight calculation unit 310, a method for selecting the most similar information in consideration of weights for wind direction, wind speed, and air volume (step S32), and in the similarity calculation unit 320, the similarity function is applied to the most similar The method of selecting the information (step S33) is the same as that already described with reference to FIG. 1, and redundant description is omitted.

As described above, when the window of the vehicle is opened with the same information or similar information (step S40), the wind having the same or the most similar wind direction, wind speed, and air volume selected by the user in the interior of the vehicle together with the opening of the window This can be provided.

Additionally, in the present embodiment, through the user output unit 600, based on information selected by the user and information stored in the database unit 100, for the wind direction, wind speed, and air volume that can be implemented inside the vehicle. Additional information may be provided (step S50), and the user may select a new wind direction, wind speed, and air volume based on this.

Furthermore, when the speed of the vehicle changes, if other conditions, for example, the number of windows, the air conditioner or the air condition of the interior of the vehicle, etc. are maintained constant, the wind direction inside the vehicle due to the speed change of the vehicle, Wind speed and air volume will change. Therefore, in this embodiment, in order to maintain the same or the most similar wind direction, wind speed, and air volume as the user's selection, that is, to maintain selection information in the determination unit 300, when the vehicle speed changes The degree of opening of the window can be further adjusted (step S60).

Thus, the user can feel the wind inside the vehicle in the same or most similar state to the selected wind direction, wind speed, and air volume, regardless of the speed change of the vehicle.

According to the embodiments of the present invention as described above, the wind direction, wind speed, and air volume in the vehicle change according to the degree of opening of the window provided in the vehicle. And the air volume is varied. Therefore, based on various information stored in the database unit, by providing the wind of the same or the most similar information to the information input by the user, it is possible to provide an optimal environment for the user.

In particular, as the speed of the vehicle changes, the degree of opening of the window can be adjusted so as to keep the wind inside the vehicle the same, and as environmental information, information on the exterior or interior design of the vehicle, as well as the number of windows and opening by window By considering the degree, the speed of the vehicle, etc., it is possible to consider all of various information that affects wind direction, wind speed, or air volume.

In this case, if the same information as the information selected by the user does not exist, the optimal wind desired by the user may be selected and provided by considering weights or applying a similarity function.

In addition, by providing the user with implementable wind direction, wind speed, or air volume information based on various environmental information, the user is provided with various information to select a more comfortable indoor environment.

Although described above with reference to the preferred embodiment of the present invention, those skilled in the art may variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that you can.

The in-vehicle wind control system according to the present invention and the in-vehicle wind control method using the same have the possibility of industrial use that can be used to control the wind direction, wind speed, or air volume of the vehicle interior.
