That is, the location providing unit 10 may include a Global Positioning System (GPS) module.

The route search unit 20 searches for a route from the starting point to the destination when the user inputs a starting point and a destination through the input interface of the vehicle navigation. At this time, the route search method is not limited, and various routes may be searched by a preset method. On the other hand, even if the departure location is not separately input, the departure location may be set based on the current location of the vehicle provided from the location providing unit 10.

In other words, when the origin and destination are determined, the route search unit 20 searches for a route using link and node information. At this time, the route search unit 20 may load terrain feature information logically connected to the link from the map information unit 30 to be described later. Here, the topographical information may include buildings, tunnels, intersections, and the like.

The map information unit 30 provides precision map information including topographic information, and includes topographic information including buildings, tunnels, and intersections, as well as POI (Point of Interest), links, and node information. Map information can be provided.

In addition, the map information unit 30 may store a high-precision map including road structure and lane information. The high-precision map may include positioning information including at least one of a road structure and a lane's size (width, height), shape, color, pattern, location (interpolation point coordinates, etc.) and material (eg, iron, plastic, etc.). It may, but is not limited to this.

The orbital information unit 40 may provide orbital information for each time and season of the path searched by the path search unit 20. That is, the orbital information unit 40 may store the orbital information of the earth by season and time and provide it to the control unit 50, thereby predicting the backlight section and the direction.

The control unit 50 predicts the backlighting section and the backlighting direction corresponding to the route to the destination by using the orbital information of the earth input from the orbit information unit 40 and the information of the surrounding topography received from the map information unit 30. It is reflected in the route information and in the predicted backlight section, a specific area of the window of the vehicle is darkened to prevent glare of the driver and the passenger in advance.

More specifically, the control unit 50 includes a backlight information prediction unit 52 for predicting backlight information and a window control unit 54 for adjusting the transparency of the window 1 of the vehicle in response to the predicted backlight information. .

The backlight information prediction unit 52 may reflect the orbit information of each hour and season in the driving route through route search. That is, the backlight information prediction unit 52 may reflect the orbit information of the earth in the searched driving route and store information about the backlight section and the backlighting direction (left, right, front, rear) of the driving route in advance. In other words, the backlight information prediction unit 52 may predict a backlight area and a backlight direction of a path searched by the route search unit 20 based on the time and season orbit information from the orbit information unit 40. .

In addition, the backlight information prediction unit 52 may predict the final backlight section and the backlight direction by reflecting the terrain feature information in the backlight section and the backlight direction predicted based on the time and season orbit information. That is, the backlight information prediction unit 52 may be able to predict the actual backlight section by using the terrain feature information of the pre-built precision map because there may be no backlight due to the surrounding terrain feature even in the backlight region.

Also, the backlight information prediction unit 52 may calculate a backlight level. For example, the backlight information prediction unit 52 is based on at least one of the distance from the sun based on the time and seasonal orbit information, the number of terrain features over a set size based on the terrain feature information, the existence of a tunnel, and the intersection. The backlight level can be calculated.

In addition, the control unit 50 may reflect the final predicted backlight section and the backlight direction in the driving route. At this time, the backlight level may be reflected to express the backlight level. For example, the controller 50 may display red when it is determined to be a severe backlighting section, and yellow when it is determined to be a weak backlighting section, and blue when it is determined to be a normal backlighting section. I can express it. That is, for example, as described above, the control unit 50 may determine that the backlight is a severe backlight section when there is no terrain feature to be blocked by the backlight at a position closest to the sun.

The window control unit 54 reflects the backlight section and the backlight direction predicted by the backlight information prediction unit 52 on the driving path, and thus, when the vehicle is located in the predicted backlight section, adjusts the transparency of the window to correspond to the predicted backlight direction. Can be adjusted.

That is, as illustrated in FIG. 3, when the window control unit 54 is positioned in the final backlight section predicted by the backlight information prediction unit 52, the window control unit 54 is positioned in the predicted final backlight direction among all the windows of the vehicle. The transparency of the corresponding glass window can be adjusted to darken. In other words, when the window control unit 54 is influenced by the sun toward the left side of the driving direction, the electric signal of the windshield 1 on the driver's side can be darkened.

Meanwhile, in the present embodiment, the glass window 1 may be formed to include a dispersed particle display (SPD). That is, the control unit 50 cuts the electrical signal flowing through the glass window 1 so that the particles are arranged irregularly to control the darkening of the glass window, and the electricity flowing through the glass window 1 is connected to the particles so that the particle arrangement is arranged and thus transparency It can be controlled so that the glass window is brightened by increasing.

At this time, in this embodiment, the control unit 50 is described as controlling the electric signal flowing through the glass window 1 to be disconnected or connected, but a driving unit capable of separately controlling the electrical signal of the glass window may be provided.

As illustrated in FIG. 2, in the method of preventing glare when driving according to an embodiment of the present invention, first, when the origin and destination are input, the controller 50 receives a route searched from the route search unit 20. Then, the route search unit 20 searches for a route from the starting point to the destination when the user inputs the starting point and the destination through the input interface of the vehicle navigation (S10).

On the other hand, even if the departure location is not separately input, the departure location may be set based on the current location of the vehicle provided from the location providing unit 10.

Next, the control unit 50 predicts the backlight information of the route searched by the route search unit 20 (S20).

That is, the control unit 50 receives the orbital information of the route searched by the route search unit 20 from the orbit information unit 40 by time and season, and the route of the searched route based on the orbit information of the time and season. The backlight section and the backlight direction can be predicted.

Then, the control unit 50 receives the precise map information including the topographical information from the map information unit 30, and reflects the topographical information in the backlight section and the backlight direction predicted based on the orbital information of each time and season. , The final backlight section and backlight direction can be predicted.

That is, the control unit 50 may reflect the orbit information of the earth in the searched driving route and store information on the backlighting section and the backlighting direction (left, right, front, rear) of the driving route in advance.

In addition, the controller 50 may predict the actual backlight section by using the terrain feature information of the pre-built precision map because the backlight may be blocked by surrounding terrain features even in the backlight region.

Also, the control unit 50 may calculate a backlight level. For example, the control unit 50 sets the backlight level based on at least one of the distance from the sun based on the orbital information according to the time and season, the number of terrain features having a size greater than or equal to the set size based on the terrain information, the existence of a tunnel, and whether or not an intersection exists. Can be calculated.

Then, the control unit 50 may control the brightness by reflecting the backlight information on the driving path to the destination (S30), and adjusting the transparency of the glass window 1 when driving according to the backlight information (S40).

That is, the control unit 50 predicts the backlighting section and the backlighting direction corresponding to the path to the destination by using the orbital information of the earth input from the orbit information unit 40 and the surrounding topographical information input from the map information unit 30. This is reflected in the driving route information and in the predicted backlight section, a specific area of the window of the vehicle is darkened to prevent glare of the driver and the passenger in advance.

In other words, the controller 50 may adjust the transparency of the glass window to correspond to the predicted backlight direction when the vehicle is located in the predicted backlight section by reflecting the predicted backlight section and the backlight direction in the driving path.

That is, when the vehicle is positioned in the final predicted backlighting section, the control unit 50 darkens the glass window 1 corresponding to the final predicted backlighting direction to prevent glare, and the vehicle position is changed again to change the backlighting section If it is outside, the transparency of the glass window 1 may be increased to make it brighter in its original state.

Meanwhile, in the present embodiment, the glass window 1 may be formed to include a dispersed particle display (SPD). That is, the control unit 50 cuts the electrical signal flowing through the glass window 1 so that the particles are arranged irregularly to control the darkening of the glass window, and the electricity flowing through the glass window 1 is connected to the particles so that the particle arrangement is arranged and thus transparency It can be controlled so that the glass window is brightened by increasing.

In addition, the control unit 50 may reflect the final predicted backlight section and the backlight direction in the driving route. At this time, the backlight level may be reflected to express the backlight level. For example, when displaying the driving route to the navigation, the control unit 50 may display red when it is determined to be a severe backlighting section, and yellow when it is determined to be a weak backlighting section, and blue when it is determined to be a normal backlighting section. I can express it. That is, for example, as described above, the control unit 50 may determine that the backlight is a severe backlight section when there is no terrain feature to be blocked by the backlight at a position closest to the sun.

As described above, in the anti-glare device and method for driving according to an embodiment of the present invention, the backlight section is predicted in advance using the orbit information and the precision map of the earth and reflected in the driving route information, thereby causing glare due to backlight. The driver's glare can be prevented before doing so to reduce the risk of accidents. In other words, it is possible to quickly and accurately prevent the glare phenomenon by fundamentally canceling the glare phenomenon in the backlight area, thereby improving user satisfaction.
