Hereinafter, preferred embodiments of the present invention will be described in more 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 the interior of the vehicle, and specifically controls the wind direction, wind speed, and air volume in the interior of the vehicle, including the vehicle. This is implemented through a combination of the open state of a window or sunroof (hereinafter, unified and described as a window).

That is, when information on the wind direction, wind speed and air volume in the vehicle desired by the user is input, various factors affecting the wind direction, wind speed and air volume in the vehicle are considered, so that the same or as similar wind direction, wind speed, and air volume can be implemented. It determines the degree of opening to each window or sunroof the vehicle contains.

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. Include.

The database unit 100 receives information on factors affecting the wind direction, wind speed, or air volume generated in the interior of the vehicle as the window of the vehicle is opened and converts it into a database.

For example, information about the windows of the vehicle, that is, information about the number of windows of the vehicle, the location of the windows, and the degree of opening of the windows may be provided in advance and converted into a database. In addition, information on the speed of the vehicle, that is, information on the speed of the currently driving vehicle may be provided in advance and converted into a database.

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

Furthermore, information on wind inside the vehicle may be provided in advance and converted into a database.

In this case, information on 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 the air conditioning or ventilation system such as an air conditioner or air conditioner inside the vehicle, and this information is a database through simulation, etc. It can be angry.

In contrast, the information on the wind inside the vehicle is substantially provided with information on the window of the vehicle and information on the speed of the vehicle, and an air conditioning or blowing system such as an air conditioner or an air conditioner inside the vehicle By adding information on the wind inside the vehicle generated by the vehicle, it can be databased through a simulation or the like, that is, a database through a simulation or the like in consideration of all factors affecting the wind inside the vehicle.

In this case, the wind inside the vehicle is affected by the degree of opening of the window, so that the wind provided from the outside is affected by the exterior design of the vehicle and the interior design of the vehicle.

Accordingly, when the database is converted through the simulation or the like, information on the exterior design or interior design of the vehicle is additionally input, so that information about the wind inside the vehicle is simulated and converted into a database.

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

Thus, when the information on the wind inside the vehicle is stored in a database, the database unit 100 includes the information classification unit 140 to classify the information on 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 are eventually changed according to combinations of the number of windows of the vehicle, the degree of opening of each window, and the vehicle speed. Of course, in this case, the vehicle's air conditioning or blowing system is additionally considered, and the wind direction inside the vehicle according to each combination of the number of windows of the vehicle, the degree of opening of each window, the speed of the vehicle and the air conditioning or blowing conditions. , Wind speed and air volume information can be classified in various ways.

For example, if the number of windows is 4, the degree of opening of the window is divided into 3 stages, the vehicle speed is divided into 10 stages, and the internal air conditioning or ventilation conditions of the vehicle are further divided into 5 stages, 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 wind direction, wind speed, and air volume information inside the vehicle in a database through a simulation or a wind tunnel experiment for each of the 4,050 cases.

In this way, the database unit 100 considers factors affecting the wind direction, wind speed, and volume of the wind inside the vehicle, and in each case, the wind direction, wind speed and air volume inside the vehicle are determined through simulation or wind tunnel experiment. Database of information.

In the user input unit 200, information on the wind direction, wind speed, and air volume in the vehicle required by the user is input by the user's input.

In this case, information on 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 be different from the wind direction, wind speed, and air volume actually databased by the database unit 100.

Accordingly, the determination unit 300 selects information that is the same as or most 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, when the same information exists, the determination unit 300 selects the corresponding information, and when the same information does not exist, the determination unit 300 selects information most similar to the information input by the user's selection. .

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

More specifically, when the wind direction, wind speed, and air volume information classified by the database unit 100 are different from the information input by the user's selection, the weight calculation unit 310 selects the most similar information, 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 air volume stored in the database unit 100 and the wind direction, wind speed and air volume by the user's selection include different individual elements, and unless all values are the same, the most similar information is selected. Standards are needed.

Accordingly, the most similar information can be selected very easily by comparing values derived by multiplying each of the first, second, and third weights by the wind direction, wind speed, and volume.

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 air volume. Thus, a value derived by assigning the first to third weights to information on the wind direction, wind speed and air volume classified and stored in the database unit 100, and information on the wind direction, wind speed, and air volume input by the user At, values derived by assigning the first to third weights are compared with each other to select information on the wind direction, wind speed, and air volume at the most similar values.

Of course, when the weight calculation results are compared, there may be a plurality of cases in which the same value is derived, and in this case, wind direction, wind speed, and air volume information determined to be most suitable can be selected.

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

That is, the similarity calculation unit 320 applies a similarity function to select the most similar information when the wind direction, wind speed, and air volume information classified by the database unit 100 are different from the information input by the user's selection. 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, a similarity function for the air volume may also be considered, but since the similarity for the air volume may be calculated in the same manner as the similarity function for the wind speed, a redundant description will be omitted.

Is the limit value of

Is located in the denominator of the fraction, so if its value is 0, it is replaced with an infinitesimal to avoid an undefined problem.

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

Thus, based on the similarity calculation result for the wind direction and wind speed of the first and second winds (the amount of wind can be calculated equally), the most similar wind can be selected, and through this, the same information as the information entered by the user Even if is not present in the database unit 100, the most similar wind direction, wind speed and air volume can be selected.

As described above, when information on the wind direction, wind speed and air volume of the inside of the vehicle is selected by the determination unit 300, the window opening 400 is The window is opened based on the condition of the condition or the blowing condition, 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 a wind that is the same or most similar 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 unit 400.

That is, if other conditions, that is, the number of windows, air conditioning or ventilation conditions inside the vehicle are constant, the wind that is the same or most similar to the wind selected by the user is blown inside the vehicle as the vehicle speed changes. To maintain, the degree of opening of the window must be varied. Accordingly, the window opening part 400 adjusts the degree of opening of the window 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 current wind direction, wind speed, and air volume inside the vehicle to the user. In FIG. 1, the user input unit 200 and the user output unit 600 are separately shown. However, as a method of realizing the present invention, one screen display device is a function of the user input unit 200 and the user output unit 600. Can be done.

Initially, when the user input unit 200 receives information on wind direction, wind speed and air volume, it should emphasize information on wind direction, wind speed and air volume that can be implemented in the current situation in preparation for information on wind direction, wind speed and air volume that cannot be implemented. I can.

Further, the user output unit 600, in addition to simply providing information on 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, it is possible to additionally provide information on wind direction, wind speed and air volume that can be implemented.

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

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

2 and 3, in the wind control method using the wind control system 10 according to the present embodiment, the method of wind control, that is, a step, will be described, and above, through the wind control system 10 Contents overlapping with the described content will be 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, information about the wind inside the vehicle is provided and stored in advance through the wind information input unit 130 (step S11), and in this case, refer to FIG. 1 for the attribute or content of the wind information provided. As described with reference.

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

In addition, information on 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, as already described, information on the external design or interior design of the vehicle may be additionally input to the database unit 100.

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 vehicle speed, and further, information on air conditioning or blowing in the vehicle As a basis, information on the wind direction, wind speed, and air volume inside the vehicle is classified for each combination of the information (step S14).

After that, the user inputs information on the wind direction, wind speed, and air volume inside the vehicle required by the user 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. It selects from information (step S30).

Thus, the window is opened based on the selected information (step S40). However, in this case, it is assumed that the opening of the window is affected only by the factor of the opening of the window, which affects the wind direction, wind speed, and volume of the wind inside 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 air conditioning or ventilation conditions inside the vehicle, the degree of opening of the windows, etc., but other conditions are kept constant. It is assumed that only the degree of openness changes.

More specifically, the determination unit 300 determines whether or not the same information as 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, if other conditions of the vehicle remain the same, that is, the speed of the vehicle is kept the same, and the air conditioning or blowing conditions by the air conditioner or air conditioner inside the vehicle are kept the same. If the case is the case, the window of the vehicle is opened equal to the degree of window opening in the same information stored in the database unit 100 (step S41).

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

Thus, based on the most similar information, 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 of selecting the most similar information in consideration of the weights for wind direction, wind speed, and air volume (step S32), and in the similarity calculation unit 320, the most similar information is applied by applying a similarity function. The method of selecting information (step S33) is the same as previously described with reference to FIG. 1, and thus, a duplicate 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 has the same or most similar wind direction, wind speed, and air volume as the wind selected by the user inside the vehicle with the opening of the window. Can be provided.

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

Furthermore, if the vehicle speed changes, other conditions, for example, the number of windows, air conditioning or ventilation conditions inside the vehicle are kept constant, the wind direction inside the vehicle due to the vehicle speed change, Wind speed and air volume will change. Therefore, in this embodiment, in order to maintain the same or 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 The degree of opening of the window may be additionally adjusted (step S60).

Thus, the user can feel the wind inside the vehicle in a state that is the same as or most similar to the previously selected wind direction, wind speed, and air volume, regardless of changes in the vehicle speed.

According to the embodiments of the present invention as described above, the wind direction, wind speed, and air volume inside the vehicle are changed according to the degree of opening of the window provided in the vehicle. Even at the same degree of opening, the wind direction, wind speed, etc. And the air volume varies. Accordingly, based on various information stored in the database unit, an optimal environment can be provided to the user by providing information that is the same or most similar to the information input by the user.

In particular, as the speed of the vehicle changes, the degree of opening of the window can be adjusted to maintain the same wind inside the vehicle, and as environmental information, information on the exterior or interior design of the vehicle, as well as the number of windows, opening by window By taking into account the degree, the speed of the vehicle, and the like, it is possible to consider all of the various information affecting the 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 user can select and provide an optimal wish desired by the user by considering a weight or applying a similarity function.

In addition, by providing information on wind direction, wind speed, or air volume that can be implemented based on various environmental information to the user, more various information is provided to the user so that a more comfortable indoor environment can be selected.
