I can.

The electromagnetic wave exposure preventing apparatus 100 may prevent a passenger in the vehicle 1 from being exposed to electromagnetic waves, and for this purpose, it may be mounted inside the vehicle 1.

The vehicle 1 described below is a vehicle including at least one electronic device 200, which is recently developed as an autonomous vehicle, an electronic vehicle, and a hydrogen fuel cell electric vehicle. It may be a concept including the like.

Referring to FIG. 2, the vehicle 1 to which the present invention is applied may be provided with the above-described electromagnetic wave exposure prevention apparatus 100. In addition, the vehicle 1 is provided with a plurality of electronic devices 200, a camera 300, a pressure sensor 400, a seat 500, an electromagnetic wave measurement sensor 600, and an access point (AP) 700 for a vehicle. Can be. The vehicle 1 shown in FIG. 2 is illustrative, and in addition to the components shown in the drawings, the vehicle 1 may be provided with any device and module required for driving.

Hereinafter, the operation of the electromagnetic wave exposure preventing apparatus 100 mounted in the vehicle 1 will be described in detail.

The database 110 may store locations of a plurality of electronic devices 200 included in the vehicle 1 and radio wave intensity (S/D) for each distance, respectively.

The plurality of electronic devices 200 included in the vehicle 1 are devices that operate by receiving electricity as power, and may be arbitrary devices that assist driving and driving. For example, the electronic device 200 may include a navigation module, a battery, a black box, an ignition system, a fuel injection system, a transmission system, an instrument and display module, a speaker, a radio, a Bluetooth module, a cassette and a CD player, and the like. .

As it operates using electricity, electromagnetic waves may be generated in the electronic device 200. Electromagnetic waves generated in the electronic device 200 are propagated in space from the source, and may have an intensity inversely proportional to the square of the propagation distance (propagation distance ² ).

Referring to FIG. 3, electromagnetic waves generated in the electronic device 200 may be propagated in a radial form along a specific direction in space from a position P of the electronic device 200. In this case, the intensity of the electromagnetic wave may be inversely proportional to the square of the propagation distance.

Each electronic device 200 may be provided at a preset position in the vehicle 1. In other words, when the vehicle 1 is produced, each electronic device 200 provided in the vehicle 1 may be mounted at a preset position according to the functional needs. In this case, the database 110 may pre-store the positions of all electronic devices 200 included in the vehicle 1.

More specifically, the database 110 may store the three-dimensional position P of each electronic device 200, respectively. Here, the three-dimensional position P is a position defined in the interior space 10 of the vehicle 1 to be described later, and may include information on the width (X), the length (Y), and the height (Z). In other words, the database 110 may store the three-dimensional position P of the electronic device 200 specified in the internal space 10 of the vehicle 1 for each electronic device 200.

Meanwhile, the radio wave intensity (S/D) by distance of the electronic device 200 is a parameter representing the intensity of the electromagnetic wave according to the distance separated from the electronic device 200, and is different depending on the type and operation state of the electronic device 200. It can have a value and can be predetermined by experimentation. In the database 110, radio wave intensity (S/D) for each distance corresponding to all electronic devices 200 included in the vehicle 1 may be stored in advance.

The radio wave intensity calculation unit 120 divides the internal space 10 of the vehicle 1 into a plurality of virtual areas (VA), and the location of each electronic device 200 stored in the database 110 and the radio wave intensity by distance. Based on (S/D), the electric wave intensity for the virtual area VA can be calculated, respectively.

The interior space 10 of the vehicle 1 may have any shape. The radio wave intensity calculation unit 120 may divide the inner space 10 of the vehicle 1 having a certain shape into a plurality of virtual areas VA. The divided virtual area VA may have any shape and arrangement.

In an example, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 along at least one horizontal plane. Accordingly, the plurality of virtual regions VA may be arranged in a row shape along at least one horizontal plane.

In another example, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 along at least one vertical plane. Accordingly, the plurality of virtual regions VA may be arranged in a column shape along at least one vertical surface.

In another example, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 into a plurality of three-dimensional virtual regions VA. In other words, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 along at least one horizontal plane and a vertical plane. Accordingly, the plurality of virtual regions VA may be arranged in a three-dimensional matrix form along a horizontal plane and a vertical plane.

Hereinafter, for convenience of explanation, it is assumed that a plurality of virtual regions VA are arranged in a 3D matrix form.

4 is a view schematically showing the interior space 10 of the vehicle 1, and for convenience of explanation, various devices provided in the interior space 10 and the appearance of the vehicle 1 are omitted.

Referring to FIG. 4, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 into a 3D matrix form of 6 * 3 * 3 (horizontal * vertical * height). Accordingly, the interior space 10 of the vehicle 1 may be divided into a total of 54 virtual areas VA.

The radio wave intensity calculation unit 120 may calculate radio wave intensity for the divided virtual region VA based on the location of each electronic device 200 and the radio wave intensity S/D for each distance.

More specifically, the radio wave intensity calculation unit 120 may calculate a distance between the location of each electronic device 200 stored in the database 110 and each virtual area VA. Subsequently, the radio wave intensity calculation unit 120 may calculate the radio wave intensity for the virtual area VA by substituting the calculated distance into the radio wave intensity S/D for each distance stored in the database 110.

The calculation of the electric wave intensity for any one virtual area VA may be performed for all the electronic devices 200 included in the vehicle 1. For example, when a navigation module and a black box are provided in the vehicle 1, the radio wave intensity for one virtual area VA is calculated by considering both the electromagnetic waves propagating from the navigation module and the black box. Can be.

As shown in FIG. 4, when the internal space 10 of the vehicle 1 is divided into a plurality of three-dimensional virtual regions VA, the radio wave intensity calculation unit 120 includes a plurality of three-dimensional virtual regions VA. According to the distance between the and each electronic device 200, the radio wave intensity for the plurality of 3D virtual regions VA may be calculated, respectively.

The three-dimensional virtual region VA may be defined by three-dimensional coordinates in the interior space 10 of the vehicle 1, and the radio wave intensity calculation unit 120 includes the coordinates of each virtual region VA and the electronic device ( The distance between each electronic device 200 and the virtual area VA may be calculated based on the coordinates (Xe, Ye, and Ze) of the three-dimensional position P of 200).

Here, the coordinates of the virtual area VA may be arbitrary three-dimensional coordinates included in the virtual area VA. More specifically, the three-dimensional virtual area (VA) is an area having a virtual volume and can be defined by a certain range of width, height, and height, and the coordinates of the virtual area (VA) are arbitrarily selected within the range. Can be

When the distance between the 3D virtual area VA and each electronic device 200 is calculated, the radio wave intensity calculation unit 120 calculates each calculated distance by distance to each electronic device 200 stored in the database 110. By substituting in the radio wave intensity (S/D), the radio wave intensity for the 3D virtual region (VA) can be calculated.

As mentioned above, since the 3D virtual area VA is an area having a virtual volume, it may be defined by a 3D coordinate range rather than a specific coordinate. Accordingly, the distance between the 3D virtual area VA and each electronic device 200 may vary depending on the location in the virtual area VA, and the electric wave intensity calculated according to the distance is also based on the location in the virtual area VA. It can be different.

In order to prevent the calculation of different radio wave intensities for any one 3D virtual area VA, the radio wave intensity calculation unit 120 includes a center point Cp of a plurality of 3D virtual areas VA and each electronic device 200. ), it is possible to calculate the propagation intensity for a plurality of three-dimensional virtual regions VA, respectively.

Referring to FIG. 4, each of the 3D virtual regions VA may have a center point Cp. The center point Cp may be defined as the center coordinates Xc, Yc, and Zc of the three-dimensional coordinate range of the virtual area VA. For example, if the virtual area VA has a width in the range of Xa to Xb, a height in the range of Ya to Yb, and a height in the range of Za to Zb, the center point Cp of the virtual area VA is (Xc=( It may be defined as the coordinates of Xa+Xb)/2, Yc=(Ya+Yb)/2, and Zc=(Za+Zb)/2).

Alternatively, the center point Cp of the 3D virtual area VA may be preset and stored in the database 110. In this case, the radio wave intensity calculation unit 120 may divide the interior space 10 of the vehicle 1 into a plurality of three-dimensional virtual regions VA based on the preset central point Cp.

Referring to FIG. 4, coordinates (Xc, Yc, Zc) of 54 center points Cp may be set in advance in the database 110, and the radio wave intensity calculation unit 120 includes the vehicle 1 internal space ( 10) can be divided into 54 3D virtual regions VA having the same volume with the coordinates (Xc, Yc, Zc) of the 54 center points Cp as the center.

The radio wave intensity calculation unit 120 includes coordinates (Xc, Yc, Zc) of the center point (Cp) of the three-dimensional virtual region (VA) calculated or preset according to the above-described method, and the three-dimensional (3D) of the electronic device 200 A distance between each electronic device 200 and the virtual area VA may be calculated based on the coordinates Xe, Ye, and Ze of the location P.

Meanwhile, since the radio wave intensity calculated as described above is calculated by considering only the factors of the electronic device 200 provided inside the vehicle 1, it is necessary to consider the electromagnetic waves outside the vehicle 1 in calculating the radio wave intensity. .

To this end, at least one electromagnetic wave measurement sensor 600 may be provided at a predetermined measurement point inside the vehicle 1, and the radio wave intensity calculation unit 120 includes a location of each electronic device 200 and a radio wave by distance. Based on the intensity (S/D), it is possible to calculate the radio wave intensity for the measurement point. Then, the radio wave intensity calculation unit 120 determines a correction value by comparing the radio wave strength with respect to the measurement point and the measured value of the electromagnetic wave measurement sensor 600, and corrects the radio wave intensity for the virtual area VA according to the determined correction value. I can.

The electromagnetic wave measurement sensor 600 may be provided inside the vehicle 1 at a preset measurement point. The position of the electromagnetic wave measurement sensor 600 is not limited, but for convenience of description, it is assumed that the electromagnetic wave measurement sensor 600 is provided on the upper surface of the interior space 10 of the vehicle 1.

Referring back to FIG. 4, the measuring point provided with the electromagnetic wave measuring sensor 600 may be defined by three-dimensional coordinates (hereinafter, measurement coordinates (Xr, Yr, Zr)). The radio wave intensity calculation unit 120 calculates the distance between the three-dimensional coordinates (Xe, Ye, Ze) and the measurement coordinates (Xr, Yr, Zr) of each electronic device 200, and calculates the calculated distance for each electronic device 200 ), you can calculate the electric wave strength for the measuring point by substituting it into the electric wave strength (S/D) for each distance.

Meanwhile, the electromagnetic wave measurement sensor 600 may be provided at the measurement point to detect both inside and outside the vehicle 1 received as the measurement point.

The radio wave intensity calculation unit 120 may determine a difference between the radio wave intensity calculated for the measurement point and the measured value of the electromagnetic wave measurement sensor 600 as a correction value. In general, since the measured value of the electromagnetic wave measurement sensor 600 is a value in which both the electromagnetic waves inside and outside the vehicle 1 are sensed, it may be greater than the radio wave intensity calculated by considering only the internal electromagnetic waves of the vehicle 1. Accordingly, the radio wave intensity calculation unit 120 may determine a value obtained by subtracting the radio wave intensity calculated for the measurement point from the measurement value of the electromagnetic wave measurement sensor 600 as a correction value.

Since the determined correction value is a value corresponding to the electromagnetic wave outside the vehicle 1, the radio wave intensity calculation unit 120 can correct the radio wave intensity by adding the correction value to the radio wave intensity calculated for each virtual region VA. have.

The area setting unit 130 may set the plurality of virtual areas VA as the safety area SA or the danger area DA based on the radio wave intensity calculated for the plurality of virtual areas VA. Here, the danger area DA may be defined as a virtual area VA having a higher radio wave intensity than the safety area SA.

In order to distinguish between the safety area SA and the danger area DA, the area setting unit 130 may use a reference intensity. The reference intensity may be set as the intensity at which the electromagnetic wave starts to affect the human body, and may be determined in advance by an experiment and stored in the database 110.

The region setting unit 130 may set the virtual region VA as the dangerous region DA when the radio wave intensity calculated for the specific virtual region VA exceeds the reference intensity. Conversely, the area setting unit 130 may set the virtual area VA as the safe area SA if the radio wave intensity calculated for the specific virtual area VA is less than or equal to the reference intensity.

The vehicle control unit 140 may identify an occupant located in the danger area DA and control the seat 500 in the vehicle 1 to move the occupant to the safety area SA.

The vehicle controller 140 may identify a passenger through the internal camera 300. The camera 300 may be provided at an arbitrary location inside the vehicle 1. The position of the camera 300 is not limited, but in order to secure a wide angle of view, the camera 300 may be provided in front of the vehicle 1 to form a photographing angle toward the rear, and the vehicle 1 It is provided on the upper part of the) to form a photographing angle toward the lower part.

Referring to FIG. 5 as an example, the camera 300 may be provided on the upper portion of the vehicle 1 to form a photographing angle toward the lower portion. Accordingly, the camera 300 may form an angle of view for the entire interior space 10 of the vehicle 1. The camera 300 may provide internal image data of the vehicle 1 to the vehicle controller 140.

The vehicle controller 140 may identify the occupant's position based on the internal image data provided from the camera 300 and may identify the occupant located in the danger area DA based on the identified occupant's position. The vehicle controller 140 may use arbitrary object detection and object tracking algorithms known in the art to identify the location of the occupant.

When the occupant's position is identified, the vehicle controller 140 compares the identified occupant's position with the danger zone DA and the safety zone SA set by the zone setting unit 130, so that the occupant ) Or within the safe area (SA) can be determined. Referring to FIG. 5 as an example, the vehicle controller 140 may compare the identified occupant's position with the danger zone DA, and identify that the occupant is within the danger zone DA according to the comparison result.

The occupant may be defined by three-dimensional coordinates in the interior space 10 of the vehicle 1. The occupant's coordinates may be any three-dimensional coordinates included in the occupant's volume identified by the camera 300. More specifically, the occupant is a subject having a certain volume, and may be defined by a certain range of width, height, and height, and the occupant's coordinates may be arbitrarily selected within the range.

The vehicle controller 140 may determine that the occupant is within the danger zone DA if the occupant's coordinates are within the 3D coordinate range defining the danger zone DA.

When the occupant is identified in the danger zone DA, the vehicle controller 140 may control the seat 500 in the vehicle 1 to move the occupant to the safety zone SA.

At least one seat 500 may be provided in the vehicle 1, and the occupant may be seated on the seat 500 when boarding the vehicle 1. The seat 500 described in the present invention may be electronically controlled according to a control signal provided from the vehicle controller 140, or may be controlled by manual operation of a passenger.

The seat 500 may move forward or backward under the control of the vehicle controller 140, may move left or right, or may rotate in a horizontal direction. In addition, the sheet 500 may include a lower sheet 510 and an upper sheet 520 that is hinged to the lower sheet 510 to form a predetermined inclination with respect to the lower sheet 510. In this case, the upper sheet The seat 520 may rotate with respect to the lower seat 510 under the control of the vehicle controller 140.

The vehicle controller 140 may control at least one of movement, rotation, and inclination of the seat 500 to move the occupant located in the danger area DA to the safety area SA. Here, the movement of the sheet 500 may be a concept including forward, backward, and left and right movement, and the inclination of the sheet 500 may mean a slope formed by the upper sheet 520 with respect to the lower sheet 510. .

Referring to FIG. 6, the vehicle control unit 140 determines the occupant identified in the first danger area DA as a first safety area SA, and the occupant identified in the second danger area DA as a second safety area ( It is possible to control the sheet 500 to move to SA).

More specifically, the vehicle control unit 140 moves the occupant from the first danger zone DA to the first safety zone SA by reversing the seat 500 on which the occupant identified in the first danger zone DA is seated. I can make it.

In addition, the vehicle control unit 140 increases the slope of the seat 500 on which the occupant identified in the second danger zone DA is seated to move the occupant from the second danger zone DA to the second safety zone SA. I can make it. In other words, the vehicle control unit 140 may rotate the upper seat 520 rearward to move the occupant from the second risk area DA to the second safety area SA.

It is natural that the above-described object tracking algorithm can be used to determine whether the occupant has entered the safety area SA.

In FIG. 6, only an example of moving the occupant to the safety area SA by reversing the seat 500 and increasing the inclination of the seat 500 is described, but the vehicle controller 140 moves, rotates and tilts the seat 500. The occupant may be moved to the safety area SA through various embodiments of controlling

As described above, the present invention controls the seat 500 of the vehicle 1 to move the occupant located in the electromagnetic wave danger area DA to the safety area SA, thereby protecting the occupant from electromagnetic waves.

On the other hand, electromagnetic waves may exert a worse influence on a specific body part of a passenger. For example, electromagnetic waves can have a worse effect on the genitals, eyes, and head than on other areas. Accordingly, the control operation of the vehicle controller 140 described above may be performed on a specific body part of the occupant.

To this end, the vehicle control unit 140 identifies the occupant's protection area (PP) located in the danger area (DA) through the internal camera 300, and controls the seat 500 to secure the identified protection area (PP). It can also be moved to the area SA. Here, the protective part PP is a body part vulnerable to electromagnetic waves, and may be preset as a genital organ, eyes, head, or the like.

Vehicle control unit 140 can identify the protection area (PP) of the occupant based on the internal image data provided from the camera 300, and the protection area (PP) is dangerous based on the location of the identified protection area (PP) It can be determined whether it is within the area DA. The object detection and object tracking algorithm described above may be used to identify the location of the protection site (PP), and in addition, various detection techniques used in the art may be used.

The protective part PP may be defined by any one 3D coordinate (eg, the center coordinate of the occupant's eye, the center of the genitals, and the center of the head) in the interior space 10 of the vehicle 1. The vehicle control unit 140 may determine that the occupant is within the danger zone DA if the coordinates of the protection area PP are within a 3D coordinate range defining the danger zone DA.

When the protection area PP is identified in the danger area DA, the vehicle controller 140 may control the seat 500 in the vehicle 1 to move the protection area PP to the safety area SA.

Referring to FIG. 7, the vehicle control unit 140 can identify the protection area PP as the head of the occupant, and move the head of the occupant identified in the danger area DA to the safety area SA. 500) can be controlled. More specifically, the vehicle controller 140 may increase the inclination of the seat 500 on which the occupant is seated to move the occupant's head from the danger area DA to the safety area SA. In other words, the vehicle controller 140 may rotate the upper seat 520 rearward so that the occupant's head moves from the danger area DA to the safety area SA.

Unlike shown in FIG. 7, the vehicle controller 140 may reverse the seat 500 as shown in FIG. 6 so that the occupant's head moves from the danger area DA to the safety area SA. .

As described above, the present invention identifies a specific body part of the occupant as a protective part (PP), and by moving the protective part (PP) located in the electromagnetic wave risk area (DA) to the safety area (SA), It can protect vulnerable body parts from electromagnetic waves.

On the other hand, the vehicle controller 140 controls the seat 500 to control the seat 500 when the occupant (or the occupant's protection area PP) is identified in the danger zone DA for more than a reference time to control the occupant (or occupant The protective part (PP) of the can be moved to the safety area (SA).

The vehicle controller 140 may continuously determine whether or not the occupant (or the occupant's protection area PP) is within the danger zone DA according to a predetermined period. The vehicle control unit 140 may count the time from a time point when it is determined that the occupant (or the occupant's protection area PP) is within the danger zone DA. When it is determined that the occupant (or the occupant's protection area (PP)) is continuously within the danger zone (DA) until the counted time becomes more than the reference time, the vehicle controller 140 performs the above-described seat 500 control operation. Can be done.

Meanwhile, the control operation of the vehicle controller 140 described above may be performed based on characteristics of the occupant. Hereinafter, the control operation according to the characteristics of the occupant will be described in detail.

Electromagnetic waves can affect children even worse than adults. Accordingly, the control operation of the vehicle controller 140 described above may be performed only when the occupant is estimated to be a child.

To this end, in one example, the vehicle controller 140 estimates the height of the occupant through the camera 300, and if the estimated height is less than the reference height, the seat 500 is controlled to safeguard the occupant located in the danger zone DA. It can be moved to the area SA. Here, the reference height is a criterion for classifying adults and children, and may be set to, for example, 140 cm.

The vehicle controller 140 may estimate the height of the occupant based on the internal image captured by the camera 300. For example, the vehicle controller 140 may estimate the height of the occupant based on the angle of view occupied by the occupant in the captured internal image. In addition to the estimation operation based on the angle of view, various image analysis methods used in the art may be applied to the operation of estimating the height of the passenger.

When the height of the occupant is estimated, the vehicle control unit 140 compares the estimated height and the reference height, and performs a control operation of the seat 500 only when the estimated height is less than the reference height, so that the occupant located in the danger zone DA Can be moved to the safe area SA.

In another example, the vehicle controller 140 identifies the weight of the occupant through the pressure sensor 400 provided in the seat 500, and if the identified weight is less than the reference weight, the vehicle control unit 140 controls the seat 500 The occupant located in) can be moved to the safety area SA. Here, the reference weight is a criterion for classifying an adult and a child, and may be set, for example, 40 kg.

A pressure sensor 400 for sensing vertical pressure may be provided inside the seat 500. When the occupant is seated on the seat 500, a vertical pressure by the weight of the occupant may be applied to the pressure sensor 400, and the vehicle control unit 140 may identify the weight of the occupant through the pressure sensor 400. .

When the weight of the occupant is identified, the vehicle control unit 140 compares the identified weight and the reference weight, and performs the seat 500 control operation only when the identified weight is less than the reference weight, and thereby the occupant located in the danger zone DA. Can be moved to the safe area SA.

As described above, the present invention identifies a child in the vehicle 1 and moves the child located in the electromagnetic wave danger area DA to the safety area SA, thereby protecting a child who is relatively vulnerable to electromagnetic waves from electromagnetic waves. I can.

On the other hand, electromagnetic waves can have an even worse effect on pregnant women, the elderly, and patients. Accordingly, the control operation of the vehicle controller 140 described above may be performed in consideration of the physical characteristics of the occupant.

To this end, the vehicle control unit 140 determines whether the occupant is a protection target based on the occupant information stored in the database 110, and if the occupant is a protection target, the vehicle control unit 140 controls the seat 500 to control the occupant located in the danger zone DA. Can be moved to the safe area SA.

In the database 110, passenger information may be stored in advance. The occupant information may include information on the physical characteristics of the occupant, and may include, for example, information on whether a person is pregnant, age, or suffering from a disease.

In one example, in order to determine whether the occupant is the subject of protection, the vehicle controller 140 may identify the occupant through a human machine interface (HMI) inside the vehicle 1.

The HMI may perform a function of visually and aurally outputting information or status of the vehicle 1 to the driver through a plurality of physical interfaces. In addition, the HMI may receive various user manipulations to control the vehicle 1 and may output driving information to the occupant. To this end, the HMI may include a number of input/output modules.

When boarding the vehicle 1, the occupant can enter the passenger's unique information through the interface of the HMI. Here, the passenger-specific information is information for distinguishing individual passengers, and may include the passenger's name, resident registration number, ID, password, and the like.

The vehicle controller 140 may identify the occupant based on the input occupant's unique information, and identify occupant information corresponding to the identified occupant with reference to the database 110.

In another example, the vehicle controller 140 may identify the occupant through the camera 300 to determine whether the occupant is a subject of protection.

More specifically, the vehicle control unit 140 can identify the occupant by applying algorithms such as iris recognition and facial recognition to the image of the occupant photographed through the camera 300, and stores occupant information corresponding to the identified occupant in a database. It can be identified by referring to (110).

When the occupant information is identified according to the method described above, the vehicle controller 140 may determine whether the occupant is a protection target based on the identified occupant information. More specifically, the vehicle controller 140 may determine the occupant as a protection target when the occupant is determined to be pregnant, an elderly, or a patient based on the occupant information.

The vehicle controller 140 may perform a control operation on the seat 500 only when it is determined that the occupant is a protection target. The details of controlling the seat 500 to move the occupant from the danger zone DA to the safety zone SA have been described with reference to FIG. 6, and thus a detailed description thereof will be omitted.

As described above, the present invention identifies a pregnant woman, an elderly person, and a patient in the vehicle 1 as protection targets, and by moving the protection target located in the electromagnetic wave risk area DA to the safety area SA, It is possible to protect passengers with physical characteristics vulnerable to electromagnetic waves.

On the other hand, before the control operation of the vehicle control unit 140 described above, the area setting unit 130 is the height of the occupant identified through the internal camera 300 is less than the reference height, or the pressure sensor provided in the seat 500 ( If the weight of the occupant identified through 400) is less than the reference weight, or the vehicle control unit 140 determines that the occupant is a protection target, the reference strength used to distinguish the safety area SA and the danger area DA is determined. Can be reduced.

In other words, when the occupant is estimated to be a child or the occupant is a subject of protection such as a pregnant woman, an elderly person, or a patient, the area setting unit 130 may set the risk area DA based on a more stringent standard. That is, by decreasing the previously set reference intensity, the number of dangerous areas (DA) in which the radio wave intensity exceeds the reference intensity may increase, and accordingly, the control frequency of the vehicle controller 140 for the seat 500 is further increased. can do.

On the other hand, the vehicle controller 140 may switch the driving mode of the vehicle to the autonomous driving mode when the occupant identified in the danger zone is located in the driver's seat.

As mentioned above, the vehicle 1 to which the present invention is applied may be an autonomous vehicle. Accordingly, the vehicle 1 may include an autonomous driving module that generates an autonomous driving path and controls the operation of the vehicle 1 according to the generated autonomous driving path.

In the driving control of such an autonomous driving module, algorithms for maintaining the gap between vehicles, preventing lane departure, lane tracking, traffic light detection, pedestrian detection, structure detection, traffic situation detection, autonomous parking, etc. can be applied. Various algorithms used in the art may be applied to move the vehicle 1 to the destination along the driving route.

Such an autonomous driving module may be selectively operated according to an operator's manipulation. For example, if the occupant wants to control the operation of the vehicle 1 by himself, the occupant may manually control the vehicle 1 after turning off the autonomous driving module. On the other hand, when the occupant wants the vehicle 1 to run autonomously, the occupant may turn on the autonomous driving module to allow the vehicle 1 to travel by itself.

Meanwhile, the vehicle controller 140 may determine whether the occupant identified in the danger area DA is located in the driver's seat. More specifically, at least one of the plurality of virtual areas VA described above may be preset as a driver's seat, and the vehicle controller 140 is a virtual area VA in which the occupant identified in the danger area DA is preset as the driver's seat. It can be determined whether the occupant is located in the driver's seat depending on whether it is within or not. Since the method of determining whether the occupant is within a specific virtual area VA has been described above, detailed descriptions will be omitted here.

When it is determined that the occupant identified in the danger zone is located in the driver's seat, the vehicle controller 140 may identify the driving mode of the current vehicle. The driving mode may be divided into a manual driving mode in which the above-described autonomous driving module is in an off state, and an autonomous driving mode in which the autonomous driving module is in an on state.

When the current driving mode of the vehicle is identified as the manual driving mode, the vehicle controller 140 may switch the driving mode to the autonomous driving mode by turning on the autonomous driving module prior to controlling the above-described seat 500. Accordingly, when the above-described seat 500 control operation is performed, the vehicle 1 runs by itself even if the occupant located in the driver's seat does not operate the vehicle 1 separately, so driving stability may be ensured.

In addition to the above-described seat 500 control operation, the vehicle controller 140 may supply power applied to at least one of the plurality of electronic devices 200 in operation when the occupant is identified in the danger zone DA. Can be blocked.

The radio wave intensity (S/D) for each distance of the electronic device 200 in operation may be used to calculate the radio wave intensity for the virtual area VA. The vehicle control unit 140 may identify at least one electronic device 200 that is not required to be operated among a plurality of electronic devices 200 in operation in order to reduce the electric wave intensity of the vehicle 1 interior space 10 as a whole. I can.

For example, the vehicle control unit 140 may identify at least one of a display module, a speaker, a radio, a Bluetooth module, a cassette, and a CD player that are not necessarily required to operate while the vehicle 1 is driving, and the identified electronic device ( 200) can be cut off.

The electric wave intensity of the interior space 10 of the vehicle 1 may be reduced as a whole according to the power cut-off operation of the vehicle controller 140.

Meanwhile, among the plurality of electronic devices 200, a display module may visually output driving information of a vehicle, and a speaker may audibly output driving information. Here, the driving information may include a current driving state of the current vehicle, information necessary for driving, information expected during driving, and the like. For example, the driving information may include a current vehicle location, a driving route, an external image, a speed, a fuel level, a real-time fuel economy, a signal violation on a driving route, and a position of a speed prevention camera.

When the vehicle control unit 140 cuts off power applied to the electronic device 200 that does not necessarily require operation, the vehicle control unit 140 may cut off only one of the display module and the speaker.

More specifically, the vehicle control unit 140 may cut off power applied to any one of the display module and the speaker having a greater radio wave intensity. For example, when the radio wave intensity generated by the display module is greater than the radio wave intensity generated by the speaker, the vehicle controller 140 may cut off power applied to the display module and supply power to the speaker. Conversely, when the radio wave intensity generated by the speaker is greater than the radio wave intensity generated by the display module, the vehicle controller 140 may cut off power applied to the speaker and supply power to the display module.

Accordingly, even if the supply of power to some electronic devices is limited in order to reduce the intensity of radio waves in the vehicle 1, one of the display module and the speaker can output driving information, and the occupant visually or audibly recognizes driving information can do.

Meanwhile, the vehicle 1 may be equipped with a vehicle AP 700. The vehicle AP 700 may be wirelessly connected to an adjacent base station through radio waves transmitted and received through an antenna provided outside the vehicle 1. The vehicle AP 700 may transmit a radio wave having a predetermined size inside the vehicle 1 to relay a connection between a wireless communication device provided in the vehicle 1 and an adjacent base station.

Meanwhile, the occupant terminal may be defined as a terminal possessed by the occupant. The occupant can board the vehicle 1 while holding the occupant terminal. The intensity of radio waves generated by the occupant terminal may increase in proportion to the distance between the occupant terminal and the connection target. For example, when the occupant terminal is directly connected to the base station than when the occupant terminal is connected to the vehicle AP 700, stronger radio waves may be generated in the interior space 10 of the vehicle 1.

The vehicle controller 140 guides access to the vehicle AP 700 (Access Point) when the occupant is identified in the danger zone DA in order to reduce the radio wave intensity of the vehicle 1 internal space 10 as a whole. Setting data can be provided to the passenger terminal.

The setting data is data for changing the settings of the occupant terminal, and may be data for setting a Wi-Fi function of the occupant terminal. Accordingly, the occupant terminal receiving the setting data may access the vehicle AP 700 through a Wi-Fi function.

Further, the setting data is a message notifying the need to change the setting to the occupant terminal, and may be a message guiding the setting of a Wi-Fi function. The occupant who recognizes the message can set the Wi-Fi function of the occupant terminal, and accordingly, the occupant terminal can access the vehicle AP 700 through the Wi-Fi function.

When the occupant's terminal accesses the vehicle AP 700, the electric wave intensity of the interior space 10 of the vehicle 1 may decrease as a whole.

As described above, the present invention cuts off power applied to the electronic device 200 in the vehicle 1 if the occupant is within the danger zone DA, or by inducing the occupant to access the vehicle AP 700, the vehicle ( 1) The electromagnetic waves generated within can be reduced overall.

The above-described present invention is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those of ordinary skill in the technical field to which the present invention belongs. Is not limited by
