The control unit 190 estimates the discoloration and coloring degree of the glass module 210 of the sunroof 200 based on the current value detected by the current detection unit 140 and controls the voltage cutoff and supply accordingly. For example, the controller 190 cuts off power when a power exceeding the range of the reversible threshold voltage or current of the coloring or decoloring of the glass module 210 stored in the storage unit 170 is applied.

Connection and detection of the connector 150 can be performed by constructing a separate sensing unit (not shown). The controller 190 detects connection and disconnection of the connector 150 and controls the supply and cutoff of voltage for discoloration of the glass module 210 of the sunroof 200.

When the ion conductor 214 is composed of an electrolyte containing a eutectic mixture, it may have a wide applied voltage range.

5 is an exploded perspective view for explaining a state in which the connector 150 is disposed in the glass module 210 according to the embodiment. As shown in FIG. 5, the glass module 210 forms a bezel 222 in a form surrounding the glass module 210. A bezel portion 221 is also formed on the vehicle body so as to correspond to the sunroof region.

The lower glass substrate 211 and the lower electrode 212 of the glass module 210 may be integrally formed. The upper electrode 216 and the upper glass substrate 217 may also be integrally formed. At this time, either the width or the length of the lower glass substrate 211, the lower electrode 212, the upper electrode 216, and the upper glass substrate 217 may be larger than the electrochromic layers 213, 214, and 215 . A connector (second connector) 152 may be disposed on a glass substrate 217 formed larger than the electrochromic layers 213, 214, and 215. The area where the connector (second connector) 152 is disposed may be disposed on the sunroof bezel 222 so that it is not exposed.

A sunroof connector (second connector) (second connector) 152 is provided at a position corresponding to the position of one side of a bezel 221 formed in the vehicle body, that is, a connector (second connector) 152 disposed in the sunroof bezel 222 (First connector) 151 that is connected to the first connector 151 and the second connector 151 are disposed.

6, the connection and disconnection state of the connector 150 when the sunroof 200 is opened and closed will be described in detail.

6 is a cross-sectional exemplary view for explaining the sunroof closing and opening operation according to the present embodiment.

Referring to Fig. 6, in the example (a), the connectors 151 and 152 are interconnected with the sunroof 200 closed. The second connector 152 connected to the glass module 210 of the sunroof 200 and the first connector 151 existing in the bezel 221 of the vehicle body are connected. At this time, the glass module 210 receives a voltage through the connector 150. In the glass module 210, a change in the current (increase in the positive direction) occurs due to the applied voltage, and the coloring mode is executed accordingly. In addition, even when the sunroof 200 is closed, the applied voltage can be shut off under the control of the control unit 190. [ That is, when the voltage application is interrupted, the colored state or the discolored state of the glass module 210 already maintained is maintained. Also, when the voltage is applied in the reverse direction based on the control of the controller 190 even when the sunroof 200 is closed, the colored glass module 210 may be discolored.

(B) shows the state in which the sunroof 200 is open, that is, the connectors 151 and 152 are disconnected. The second connector 152 connected to the glass module 210 of the sunroof 200 and the first connector 151 existing in the bezel 221 of the vehicle body are spaced apart from each other. At this time, the glass module 210 maintains the colored state when the connector 150 is colored and separated from the connected state. Or the colored state is maintained, and then the color gradually changes to the decolored state.

The coloring and decoloring operation of the sunroof according to the present embodiment will be described in detail below with reference to FIGS.

FIG. 7 is an operational flowchart for explaining the sunroof coloring and discoloring operation according to the present embodiment, and FIG. 9 is an exemplary view for explaining voltage and current changing states in sunroof coloring and decoloring according to this embodiment.

7 and 9, the control unit 190 receives the sunroof operation control signal through the user input unit 160. Specifically, the control unit 190 receives the sunroof operation control signal through the user input unit 160, A control signal for closing or opening can be inputted.

In the present embodiment, a control signal for closing the sunroof is inputted.

If the sunroof closing request signal is detected, the controller 190 determines whether the connector 150 is connected or not (S720).

The control unit 190 detects the sunroof closed mode when the first connector 151 formed in the vehicle body and the second connector 152 formed in the sunroof 200 glass module 210 are detected to be coupled to each other (S730)

The control unit 190 determines whether the power is turned on in the sunroof closing mode in step S740. Specifically, the control unit 190 controls the power supply controller 120 to supply power to the sunroof 200, It is judged whether authorization is made.

The controller 190 controls the glass module 210 of the sunroof 200 to apply a voltage for coloring and the glass module 210 operates in a color mode or a color fading mode by a current generated according to the voltage (S750)

Specifically, it operates in the coloring or discoloring mode depending on the application direction of the applied voltage. For example, when the forward voltage is applied, the glass module 210 operates in the coloring mode. When the reverse voltage is applied, the glass module 210 operates in the decolorizing mode. Therefore, even if a voltage is applied, the glass module 210 may be colored or discolored depending on the direction of voltage application.

At this time, the control unit 190 may output status information according to the coloring or discoloring mode through the output unit 180. [ (S760) For example, the controller 190 controls the glass module 210 of the sunroof 200 to be in a closed state through the display unit 181, operates in a color mode according to the voltage applied, (Absorption rate) in various contents such as image, image, and text.

The control unit 190 receives the sunroof operation control signal in step S710 and confirms whether the connector 150 is connected in step S720. As a result, the controller 190 determines that the connection of the first connector 151 and the second connector 152 The glass module 210 determines that the sunroof 200 is in an open state (S770). Accordingly, since the supply of the voltage to be applied through the controller 100 is impossible, Transition from the colored state to the decolored state after the critical time.

Also, even if the control unit 190 detects the closed state of the sunroof 200 (S730), the glass module 210 maintains the previously colored or discolored state in the state where no voltage is applied.

At this time, the controller 190 may output information on whether the sunroof is open or closed or discolored through the output unit 180. In operation S790,

Specifically, the controller 190 controls the glass module 210 of the sunroof 200 to be in an opened state or a closed state through the display unit 181, , And outputs information on the degree of discoloration (absorption rate) with time in various contents such as image, image, and text.

The coloring and decoloring operation of the sunroof according to the voltage application as described above will be described with reference to Fig. 9 (a).

Referring to FIG. 9A, a voltage for coloring the glass module 210 is applied during a voltage application period (ON) as indicated by a line 910 showing a power supply state. The voltage applied to the glass module 210 may be 2V.

The glass module 210 is colored as shown in the absorption diagram line 930 in Fig. (B) during the period Fw during which the voltage is applied in the normal direction. Particularly, in the first section Fw_a of the voltage application period Fw, the coloring rate of the glass module increases rapidly. The coloring ratio is increased at a low speed in the second section Fw_b when the critical time elapses during the voltage application period ON (when the coloring proceeds beyond the threshold value).

Then, when the reverse voltage Rev is applied, the glass module 210 transitions to the decoloring mode. At this time, in the first period (Rev_a) of the reverse voltage section (Rev), the decoloring rate of the glass module 210 rapidly decreases. In the second period (Rev_b) where the critical time has elapsed, the discoloration mode is terminated.

Therefore, in the embodiment, when the connector is contacted and a voltage is applied to the glass module, the coloring mode is advanced. If the voltage is not applied to the glass module even if the connector is disconnected or the connector is in contact, It is ..

Hereinafter, the voltage control operation in the sunroof color mode operation will be described in detail with reference to Figs. 8 and 9. Fig.

Fig. 8 is an operational flowchart for explaining the sunroof coloring control operation according to the present embodiment.

8 and 9, in a closed state of the sunroof to which the connector 150 is connected, the controller 190 controls the power supply to the window module 210 of the sunroof 200, Mode (S751).

The current detector 140 detects the current applied to the glass module 210. Specifically, the driving unit 130 senses a variable current amount corresponding to the discoloration operation of the glass module 210, and the current detection unit 140 detects the current sensed by the driving unit 130. In operation S752,

The control unit 190 estimates the degree of coloring of the glass module 210 based on the current detected by the current detecting unit 140. More specifically, the control unit 190 determines whether the glass module 210 has discolored And the driving unit 130 senses a current application. At this time, the current measuring unit 140 measures the current sensed by the driving unit 130, and the control unit 190 confirms the coloring information based on the current measured by the current measuring unit 140.

The control unit 190 determines whether the current change amount detected by the current detection unit 140 is less than or equal to the reference change amount. Or whether the current value is equal to or greater than the reference current value. Accordingly, the degree of coloring of the estimated glass module 210 is compared with the reference coloring degree based on the amount of current detected by the current detecting unit 140 (S754)

The controller 190 cuts off the power applied when the coloring of the glass module 210 progresses beyond the reference value according to either the current change amount, the reference current value, or the degree of coloring (S755).

9 (b) is a graph showing changes in the amount of current due to coloration or discoloration of the glass module 210. As shown in FIG.

9 (b), the controller 190 applies a current 940 during the coloring period (ON), and the coloring of the glass module 210 proceeds.

In the early stage of the coloring period (ON), the amount of current flowing into the glass module 210 is high, but the amount of current decreases as the coloring progresses.

The controller 190 checks whether the current variation detected by the current detector 140 is within the threshold level or the current value reaches the threshold value or less. The critical range of the current change amount may be -75 to 10 μA / sec. The threshold value range of the current value may be -1.2 to 2.8 mA. The control unit 190 may estimate the coloring rate of the glass module 210 according to the amount of current change or the amount of current detected by the current detection unit 140 to determine whether the coloring rate has reached a critical range. The coloring rate threshold range can be expressed as the transmittance T%. However, the critical range of the current change amount, the critical range of the current value, and the threshold value range for the coloring rate described above may vary depending on the embodiment or the characteristics of the element.

If the current value is within the critical range or the coloring rate reaches the critical range as described above, the controller 190 cuts off the voltage to supply the voltage to the glass module 210 .

In the example of FIG. 9 (b), the voltage supply is stopped when the current falling period in the coloring period ON coincides with the above-mentioned condition and reaches the threshold range 945a. Thus, by shutting off the voltage supply in the critical range as described above, the voltage supply efficiency can be improved and the glass module 210 can be prevented from deteriorating.

Also, even if the voltage supply is interrupted, the colored state can be maintained (950) by the memorial effect during the critical time.

In addition, the current increases in the positive (+) direction during the period of the colored state where the voltage is supplied, but the current increases in the negative (-) direction in the decolored section in which the voltage supply is interrupted. Therefore, after the supply of the voltage is stopped, the glass module 210 is maintained in the colored state by the memorial effect, but is discolored after the critical time. The memorial effect may vary depending on the characteristics of the materials constituting the electrochromic layers 412, 413 and 414 of the glass module 210.

The control unit 190 may detect the coloring state and the discoloring state by checking the amount of current according to the voltage application as described above, and may output the coloring rate and discoloration ratio information through the output unit 180 so that the user can recognize the amount.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
