The vehicle 100 according to the disclosed invention aims at providing desired information to a desired projection point by adjusting a projection angle of the projection unit 150. [ At this time, the projection point may be a fixed specific point, and may be variable depending on time or an external situation. Hereinafter, for convenience of explanation, it is assumed that desired information is provided to a fixed projection point.

In order to provide desired information to the projection point fixed through the projection unit 150, the projection angle of the projection unit 150 must be adjusted as the vehicle 100 moves. Hereinafter, the control unit 160 controls the projection unit 150 150 will be described in more detail.

[

5, the vertical distance x from the projection point P to the front of the vehicle 100 changes from x1 to x2 as the vehicle 100 moves. At this time, the degree of change of the distance is determined based on the velocity v of the vehicle 100. For example, when the vehicle 100 moves at the first speed, the degree of change in distance from the projection point to the front of the vehicle 100 becomes larger than when the vehicle 100 moves at the second speed lower than the first speed. The control unit 160 calculates the vertical distance x1 from the projection point P determined on the basis of this principle to the front of the vehicle 100, the vertical distance y from the bottom surface to the projection unit 150, The projection angle a of the projection unit 150 can be controlled based on the speed information of the projection unit 150. [

The process of controlling the projection angle of the controller 160 may be expressed by Equations 1 to 3 below.

Equation 1

Equation 2

Equation 3

In Equation 1, a1 denotes a projection angle of the projection unit 150 at a first time, x1 denotes a vertical distance from the projection point to the front of the vehicle 100 at a first time, y denotes a vertical distance from the bottom surface to the projection unit 150, (150).

In Equation 2, a2 denotes a projection angle of the projection unit 150 at a second time, x2 denotes a vertical distance from the projection point to the front of the vehicle 100 at a second time, y denotes a vertical distance from the bottom surface to the projection unit 150, (150).

In Equation 3, v denotes the speed of the vehicle 100, and t denotes an interval from the first time to the second time, that is, the time when the vehicle 100 has moved to the projection point.

The control unit 160 can control the projection angle of the projection unit 150 based on the movement information of the vehicle 100 through the process of Equations 1 to 3. [

The control unit 160 may determine whether to project the image information according to the distance of the vehicle 100 from the projection point.

The control unit 160 may control the projection unit 150 to project the image information generated in the image forming unit 130 when it is determined that the vehicle 100 is separated from the projection point by a predetermined second distance. Thereafter, as the vehicle 100 advances toward the projection point direction, the projection angle of the projection unit 150 may be adjusted through the process described above to project image information at a desired point.

The control unit 160 may control the projection unit 150 not to project the image information if it is determined that the vehicle 100 has entered the third distance range set in advance according to the embodiment. Where the third distance may be a shorter distance than the second distance.

The control unit 160 may control the projection unit 150 to stop the projection of the image information at the projection point when it is determined that an obstacle exists between the vehicle 100 and the projection point or an obstacle exists at the projection point . On the other hand, the controller 160 can control the projection unit 150 to project the image information again if it is determined that the obstacle is removed. Here, the obstacle may be a concept including a pedestrian or another vehicle.

The control unit 160 may determine whether an obstacle exists by providing the image information collected from the photographing unit to the image processing process. However, the present invention is not limited thereto, and it is of course possible to determine whether an obstacle is present or absent through an infrared sensor installed in the vehicle 100 separately.

The control unit 160 can prevent damage to the pedestrian or other vehicles due to the projected image information through the control process as described above.

Hereinafter, various information projection methods of the vehicle 100 according to one embodiment will be described.

FIG. 7 is a view showing an information projection method in a child getting off mode of the vehicle 100 according to an embodiment. And FIG. 8 is a diagram illustrating an information projection method in an emergency mode according to an embodiment.

Referring to FIG. 6, the vehicle 100 according to an embodiment can project the image information to the rear side of the vehicle 100 in the passenger getting-off mode, thereby informing the passenger of the passenger's getting off.

Referring to FIG. 7, the vehicle 100 according to one embodiment can notify that the child is getting off by projecting image information on the side of the vehicle 100 in the child off mode. At this time, the vehicle 100 can determine a specific point of the vehicle positioned on the side of the vehicle 100 as a projection point.

8, the vehicle 100 according to one embodiment may notify the surrounding vehicle 100 or the pedestrians of an emergency by projecting image information to a plurality of points around the vehicle 100 in the emergency mode . Here, a plurality of points around the vehicle 100 may be a specific point of at least one of a road or a lead.

The information display method in each mode is not limited to those shown in Figs. 6 to 8. According to the embodiment, the image information can be projected to a plurality of points even in the passenger getting off mode and the child get off mode, As shown in FIG.

In the foregoing, various embodiments of the vehicle 100 according to one embodiment have been described. Next, a control method of the vehicle 100 according to an embodiment will be described.

9 is a flowchart illustrating a control process of the vehicle 100 according to an embodiment of the present invention.

9, the control process of the vehicle 100 according to an embodiment may include collecting information about the vehicle 100 from the information collecting unit 120, Determining a projection point 220, controlling the projection angle 230 to project the image information to the determined projection point 230, and projecting the image information to the determined projection point 240.

The control process of the vehicle 100 according to the disclosed invention assumes that the image information projection mode of the vehicle 100 is preset in the input unit 110. [ The image information projecting mode of the vehicle 100 may include at least one of a bus stop entry mode, a passenger getting off mode, a child get off mode, and an emergency mode. Hereinafter, among the image information projection modes of the vehicle 100, The control procedure of the vehicle 100 will be described.

In the control process of the vehicle 100 according to the embodiment, the step of collecting information about the vehicle 100 from the information collection unit 120 may be performed (210).

The step of collecting information about the vehicle 100 may include at least one of collecting image information about the vehicle 100 or collecting sensor value information about the vehicle 100. [ Collecting the sensor value information about the vehicle 100 may include collecting sensor value information collected from the sensor array around the vehicle 100 through a communication unit provided in the vehicle 100. [ The sensor array can be installed around the bus stop to collect information on entry and exit of the vehicle 100 as described above and will not be described below in connection with the information collection process around the vehicle 100 .

When the information collected through the information collecting unit 120 is transmitted to the controller 160, a step of determining the projection point may be performed based on the collected information (220).

The step of determining the projection point based on the collected information may include determining a predetermined point of the bus stop as a projection point based on the image information collected by the photographing unit or determining a point spaced by a predetermined first distance from the preceding vehicle Determining a projection point, or determining a specific point of at least one of a road and a lead as a projection point.

When the projection point is determined, a step of generating image information to be projected onto the projection point may be performed according to the set projection mode. It is needless to say that the step of generating image information is not necessarily performed after determining the projection point, and may be performed simultaneously with or after the step of controlling the projection angle, which will be described later. The overlapping description of the steps of generating the image information will be omitted.

Once the projection point is determined, a step 230 may be performed to calculate the projection angle to project the image information to the determined projection point.

The step of calculating the projection angle includes calculating a projection angle of the projection unit 150 based on the vertical distance from the projection point to the front of the vehicle 100, the vertical distance from the bottom surface to the projection unit 150, And computing a projection angle. Here, the vertical distance from the projection point to the front of the vehicle 100 may vary as the vehicle 100 is moved, and may vary depending on the speed at which the vehicle 100 moves.

When the projection angle is computed, a step of projecting the image information to the projection point based on the computed projection angle information may be performed (240).

The control unit 160 may control the projection unit 150 so that the image information is projected to the projection point. According to the embodiment, when an obstacle is detected in at least one of the vehicle 100 and the projection point and the determined projection point in the process of projecting the image information to the projection point, the projection process of the image information may be interrupted.

More specifically, projecting the image information may include determining whether an obstacle is present between at least one of the vehicle 100 and the projection point and the determined projection point. The control unit 160 may temporarily suspend the projection of the image information if it is determined that an obstacle exists between the vehicle 100 and the projection point or at the projection point. On the other hand, if it is determined that the obstacle is removed, the control unit 160 can continuously project the image information at the projection point. Here, the obstacle may be a concept including a pedestrian or another vehicle, and a description overlapping with the above description will be omitted.

As described above, various embodiments of the vehicle 100 and the control method thereof according to the embodiment have been described. It is to be understood that the technical idea of the invention is not limited to the above-described embodiments, but is to be broadly construed as a concept including modifications within a range that can be easily conceived by those skilled in the art.
