When driving in a daytime with high direct sunlight, it is difficult to secure visibility because of strong direct sunlight. In summer, there is a problem that the skin is damaged by strong ultraviolet rays flowing into the car. Several methods have been proposed for blocking. First, most cars have a car sun visor installed in the driver's seat and front passenger's seat to prevent obstructing the front view of the driver, but the sun visor has to be used in such a way that the driver spreads out at the bottom to block the sunlight when the driver is in the sun. This was only to block the sunlight coming into the area, regardless of the sunlight the driver felt.

Another direct sunlight blocking method is to attach the sunshade directly to the glass to block the sunlight, which can be used on the side glass but can not be used on the front glass. And, as with the sun visor, there was an inconvenience that the sunshade had to be moved when the position of the sunshine was changed while driving. Moving while driving was more likely to cause an accident. In addition, although a method of tinting the glass itself is used, there is a disadvantage that it is not ensured in the case of nighttime operation or rain, and it must be removed at the time of regular inspection. That is, the conventional sunlight blocking device does not block the sunlight of the range desired by the driver, and thus discomforts the mood of the driving driver, thereby hindering safe driving.

In the transparency control apparatus for a glass for a vehicle according to an embodiment, when a gesture of a predetermined user is sensed, the control unit determines transparency of a region of the glass for a vehicle corresponding to a position where the gesture is sensed.

In the transparency control apparatus for a glass for a vehicle according to an embodiment, the sensing section obtains illuminance information on the amount of light irradiated to the vehicle according to a time unit set based on weather information and time information of a place where the vehicle is located.

An apparatus for controlling transparency of a glass for a vehicle according to an embodiment further includes a user input unit for obtaining a user input requesting a transparency change for at least a partial area of the glass for a vehicle from a user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are block diagrams of an apparatus 100 for controlling transparency of a glass for a vehicle according to an embodiment.

The transparency control apparatus 100 (hereinafter, a glass control apparatus for a vehicle) for a vehicle glass according to an embodiment can control the transparency of a vehicle glass by applying a voltage to the vehicle glass provided in the vehicle. Here, the glass for a vehicle may be composed of a material such as a cholesteric LCD and a photonic crystal material, whose optical characteristics (for example, transparency) are changed according to changes in the magnitude of an applied voltage. For example, when a cholesteric LCD or a photonic crystal material is used to produce automotive glass, a voltage between 40 volts and 60 volts may be applied to convert the transparency of the automotive glass. Cholesteric LCD or automotive glass using photonic crystal materials can be converted to a transparent state at 45 volts or less and to an opaque state at 55 volts or more. However, the above-mentioned examples are only examples of the material constituting the glass for vehicles, and the material constituting the glass for vehicles is not limited thereto. On the other hand, the glass for vehicle is opaque depending on the applied power, and on the other hand, transparency can be maintained so that the user can see the outside of the vehicle inside the vehicle due to the nature of the particles.

1, an apparatus 100 for controlling transparency of a glass for a vehicle according to an exemplary embodiment may include a sensing unit 110, a control unit 120, and a voltage application unit 130. As shown in FIG. However, not all illustrated components are required. The on-vehicle glass control apparatus 100 may be implemented by a greater number of components than the illustrated components, and the on-board glass control apparatus 100 may be implemented by fewer components.

2, the glass control apparatus 100 for a vehicle according to one embodiment includes a user input unit 140, a communication unit 150 (not shown) in addition to the sensing unit 110, the control unit 120, and the voltage application unit 130. [ And a memory 160, as shown in FIG.

The sensing unit 110 acquires the illuminance information about the position information of the user who has boarded the vehicle and the light quantity irradiated to the vehicle. For example, the sensing unit 110 may determine the position information of the user based on whether the movement of the user is detected within a predetermined sensing range in the in-vehicle glass control apparatus 100. [

Also, the sensing unit 110 can measure the amount of light irradiated onto the vehicle glass provided in the vehicle. The sensing unit 110 may acquire illuminance information for each region when the amount of light irradiated for each region of the vehicle glass is different.

Meanwhile, the sensing unit 110 according to an exemplary embodiment may acquire illuminance information on the amount of light irradiated to the vehicle according to a time unit set based on weather information and time information of a place where the vehicle is located.

The sensing unit 110 includes a magnetism sensor 111, an acceleration sensor 112, a temperature / humidity sensor 113, an infrared sensor 114, an illuminance sensor 115, a position sensor But is not limited to, at least one of a GPS (Global Positioning System) 116, an air pressure sensor 117, a proximity sensor 118, and an RGB sensor 119. The function of each sensor can be intuitively deduced from the name by those skilled in the art, so a detailed description will be omitted.

The control unit 120 typically controls the overall operation of the glass control apparatus 100 for a vehicle. For example, the control unit 120 may include a sensing unit 110, a voltage application unit 130, a user input unit 140, a communication unit 150, a memory 160, and the like by executing programs stored in the memory 160 Can be controlled as a whole.

The control unit 120 selects at least a partial region of the vehicle glass provided in the vehicle based on the position information obtained by the sensing unit 110 and the obtained roughness information. For example, the control unit 120 can distinguish the vehicle glass as a plurality of regions, and calculate the illuminance values for each of the plurality of regions based on the obtained illuminance information. The control unit 120 can select at least a region where the calculated illuminance value exceeds the threshold value.

 The control unit 120 determines the transparency of at least some selected regions. On the other hand, the transparency can be determined based on the amount of light transmitted through the vehicle glass. For example, transparency can be classified into five values depending on the amount of light transmitted through the vehicle glass. In addition, the control unit 120 may acquire, from the memory 160, information about the magnitude of the voltage to be applied in order to control the in-vehicle glass according to the respective transparency values.

When the gesture of a predetermined user is sensed, the controller 120 determines the transparency of the region of the glass for the vehicle corresponding to the detected position of the gesture. The control unit 120 may change the transparency of the area of the glass for the vehicle when the gesture of the user sensed in the vehicle corresponds to the predetermined gesture. For example, when the user takes a gesture that hides his or her eyes due to the light irradiated inside the vehicle, the control unit 120 can detect the gesture of the user and change the transparency of the glass for the vehicle. On the other hand, the controller 120 can change the transparency of the area corresponding to the position where the user's gesture is sensed in the vehicle glass. Further, the transparency value of the vehicle glass can be determined according to the kind of the user's gesture.

The voltage application unit 130 applies a voltage to at least a part of the region selected according to the transparency determined by the controller 120.

The user input unit 140 may obtain a user input from the user of the in-vehicle glass control apparatus 100 requesting a change of the transparency of the selected region in the in-vehicle glass provided in the vehicle.

The communication unit 150 may include at least one component that enables communication between the vehicle glass control apparatus 100 and another terminal or between the vehicle glass control apparatus 100 and another server. For example, the communication unit 150 may include a WLAN communication unit, a Zigbee communication unit, an IrDA (infrared data association) communication unit, a WFD (Wi-Fi Direct) communication unit, an UWB (ultra wideband) communication unit, But is not limited thereto.

The communication unit 150 according to an exemplary embodiment may receive weather information of a place where the vehicle is located from another server.

The memory 160 may store a program for processing and controlling the control unit 120, and may store input / output data. For example, the memory 160 may store illuminance information obtained on a predetermined time basis. In addition, the memory 160 may store information on the magnitude of the voltage corresponding to the transparency value.

3 illustrates a method for controlling the transparency of a glass for a vehicle corresponding to a position of a user among the glass for a vehicle 310, 320, and 330 provided on each side of the vehicle, according to an embodiment of the present invention. Fig.

3, the vehicle glass control apparatus 100 according to an embodiment includes a first vehicle glass 310 on the front surface of the vehicle, and a second vehicle glass 320 and a third vehicle glass (330). 3, the first glass for a vehicle 310, the second glass for a vehicle 320 and the glass for a third glass 330 are exemplified. However, this is merely an example, (Not shown) can also be controlled by the glass control apparatus 100 for a vehicle.

The glass control apparatus 100 for a vehicle may detect movement of a user in the vehicle. For example, the in-vehicle glass control apparatus 100 can detect an operation such as a user turning a steering wheel, changing a gear, or the like in a driver's seat. The on-vehicle glass control apparatus 100 can calculate the illuminance values of the first vehicle glass 310 and the second vehicle glass 320 that can project light to the user located on the driver's seat based on the obtained illuminance information have.

The in-vehicle glass control apparatus 100 can change the transparency of the first vehicle glass 310 and the second vehicle glass 320 when the calculated illuminance value exceeds a preset threshold value. For example, the in-vehicle glass control apparatus 100 may change the first glass for a vehicle 310 and the second glass for a vehicle 320 opaque. Here, the transparency values of the first glass for a vehicle 310 and the second glass for a vehicle 320 can be determined based on the illuminance value. Here, the in-vehicle glass control apparatus 100 may store in advance information on the transparency value corresponding to the illuminance value so that the driver can maintain an optimized visual field during driving.

4 is a view for explaining a method of controlling transparency by selecting at least a partial region according to the amount of light irradiated for each region of the glass for a vehicle according to an embodiment of the present invention.

Referring to FIG. 4, the vehicle glass provided in the vehicle can be distinguished into a plurality of regions. The vehicular glass control apparatus 100 can calculate the illuminance value for each distinguished area. The in-vehicle glass control apparatus 100 can select a part of the area where the calculated illuminance value exceeds the threshold value.

The glass control apparatus 100 for a vehicle may apply a predetermined voltage to the selected partial areas 411, 413, and 415 to change the transparency of the selected partial area. The glass control apparatus 100 for a vehicle according to an embodiment of the present invention is designed to prevent the time from being delayed in order to change the transparency by applying a voltage to the entire area of the glass for a vehicle. And the voltage can be applied only to the selected regions 411, 413, and 415.

5 is a view for explaining a method of controlling the transparency of a glass for a vehicle by detecting a user's gesture according to an embodiment of the present invention.

Referring to FIG. 5, the glass control apparatus 100 for a vehicle according to an embodiment can detect the gesture of a user and control the transparency of the glass for vehicles 510 and 515 provided in the vehicle. Further, the position, area, and transparency value of the vehicle glass controlled according to the type of the user's gesture can be determined. The in-vehicle glass control apparatus 100 can previously store the position, area, and transparency value of the vehicle glass corresponding to the user's gesture in the memory.

For example, when detecting the first gesture 520 of the user, the glass control apparatus 100 for a vehicle may change the transparency of the glass for cars 510 and 515 corresponding to the detected position of the first gesture 520 have. According to another example, the on-vehicle glass control apparatus 100 can select a glass for a vehicle corresponding to a position where the gesture is sensed when a user detects a gesture hiding his / her eyes due to sunlight. The glass control apparatus 100 for a vehicle may select a region where the illuminance value exceeds a threshold value for the selected glass for a vehicle and apply a voltage to the selected region to increase the opacity.

On the other hand, according to another embodiment, the in-vehicle glass control apparatus 100 can select an area corresponding to the user's gesture on the in-vehicle glass based on the user's gesture. For example, when the user draws a figure with a finger within a predetermined distance range from the vehicle glass, the vehicle glass control apparatus 100 can select the vehicle glass region corresponding to the figure. The in-vehicle glass control apparatus 100 can control the transparency of the selected in-vehicle glass region. Here, the transparency can be determined according to the distance between the vehicle glass and the position where the user's gesture is sensed. However, this is only an embodiment, and the present invention is not limited thereto.

In addition, the vehicle glass control apparatus 100 according to an embodiment can obtain illuminance information for each region when the amount of light irradiated for each region of the vehicle glass is different.

In step S620, the in-vehicle glass control apparatus 100 determines the transparency of at least a part of the area of the vehicle glass provided in the vehicle based on the obtained position information and the obtained roughness information.

The on-vehicle glass control apparatus 100 selects at least a partial area of the vehicle glass provided in the vehicle based on the obtained positional information and the obtained roughness information. For example, the in-vehicle glass control apparatus 100 can distinguish the in-vehicle glass into a plurality of regions, and calculate the illuminance values for each of the plurality of regions based on the obtained illuminance information. The in-vehicle glass control apparatus 100 can select at least a region where the calculated illuminance value exceeds the threshold value.

The vehicle glass control apparatus 100 according to an embodiment determines the transparency of the area of the vehicle glass corresponding to the position where the gesture is sensed when the predetermined user's gesture is sensed. The vehicle glass control apparatus 100 can change the transparency of the area of the vehicle glass when the gesture of the user detected in the vehicle corresponds to the predetermined gesture.
