Hereinafter, an embodiment of an apparatus and method for preventing vehicle collision using a head-up display according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a view illustrating a schematic configuration of a vehicle collision avoidance apparatus using a head-up display according to an embodiment of the present invention.

1, the vehicle collision avoidance apparatus using the head-up display according to the present embodiment includes a sensor unit 110, a travel direction detection unit 120, a head-up display 130, a control unit 140, And a camera unit 150.

The sensor unit 110 detects an obstacle in front of the vehicle or an obstacle behind the vehicle.

The sensor unit 110 detects a straight line distance and a position from the vehicle to the obstacle based on the traveling direction of the vehicle.

For example, the sensor unit 110 may include a LIDAR sensor, and the sensor unit 110 may further include other types of obstacle detection sensors (e.g., an ultrasonic sensor, an infrared sensor, etc.).

For reference, the LIDAR (Light Detection And Ranging) sensor is a sensor that can be used to measure the position coordinates of a reflector by emitting a laser pulse and measuring the time of reflected and returning.

The sensor unit 110 detects a signal reflected from an obstacle (e.g., a pedestrian, a vehicle, a wall, an object, and the like) in the viewing direction (or the vehicle traveling direction) to detect a distance between the obstacle and the vehicle, Can be detected.

The controller 140 determines the possibility of collision with the obstacle in the viewing direction (or the vehicle traveling direction) based on the information detected through the sensor unit 110. [

For example, when the vehicle passes the vehicle ahead of the road, the control unit 140 determines the possibility of collision with the preceding vehicle or the possibility of collision with the road guide. When the vehicle is parked, And the possibility of collision with the front and rear wall surfaces.

The traveling direction detecting unit 120 detects a direction in which the vehicle is running (e.g., straight ahead or backward). The traveling direction detecting unit 120 receives information on the traveling direction (e.g., straight ahead or backward) from the ECU of the vehicle or detects the traveling direction through a sensor (not shown) or the like that detects the direction in which the vehicle & can do.

The traveling direction information detected by the traveling direction detecting unit 120 is output to the controller 140. [

Accordingly, the control unit 140 outputs an image (e.g., a top view image or an overview view image) photographed through the camera unit 150 through the head-up display 130 based on the traveling direction information of the vehicle .

At this time, the controller 140 changes the output time point of the image (e.g., the top view image or the surround view image) (e.g., the driver's viewpoint, the observer's point of view, etc.) so that the user can recognize the close- (E.g. collision alarm information) by using a specific color or a specific image, or recommending a recommendation guideline (that is, collision avoidance information) that can avoid collision , Steering direction guidelines), thereby allowing the driver to adjust the steering to avoid collisions.

If the vehicle is capable of automatic steering (i.e., unmanned steering), the control unit 140 may perform automatic steering in a direction in which collision avoidance is possible.

The camera unit 150 includes at least one camera (CAM-1 to CAM-N) including a digital image sensor as a means for capturing an image of the surroundings of the vehicle (e.g., front, side, .

The camera unit 150 may include a Far Infra Red (FIR) camera and / or a CMOS camera (or a CCD camera).

For reference, the CMOS camera (or a CCD camera) captures light similar to that of a human eye because it acts to sense and project light in a visible light region. The FIR camera acquires an image by projecting light in an infrared band that a person can not see. Particularly, the FIR band has the advantage of distinguishing the temperature because the wavelength changes according to the temperature.

As shown in FIG. 2, the camera unit 150 includes at least four cameras CAM-1 to CAM-4 installed on the front / rear / left / right sides of the vehicle to implement the top view or the surround view image. In addition, in order to enhance the completeness of the top view or the surround view image and to prevent a shooting dead zone from being generated, an additional camera (CAM- 5, CAM-6) can be installed.

3 (a), the control unit 140 determines whether the image captured through the camera unit 150 based on the collision probability determined on the basis of the running direction information of the vehicle A view image or an ambient view image) according to a predetermined method and outputs the processed image through the head-up display 130.

For example, in order to allow the user to recognize the proximity of the obstacle close to the obstacle during running or parking, the controller 140 controls the image displayed on the head-up display 130 (E.g., driver's viewpoint, observer's point of view) of the surrounding view image. In addition, the width of the vehicle is displayed as a line, and the top view image or the surround view image is displayed together so that the driver can easily get out of a narrow space.

Here, the driver's view is a view showing a near portion at an angle (direction) that can be displayed when the driver looks at it, and the viewer's view is a view Quot;

At this time, the close part (for example, the close part with a high possibility of collision) may be displayed in an enlarged manner or the color information of the corresponding side may be displayed differently depending on the proximity of a specific color (for example, (I.e., collision alarm information) may be additionally displayed using a particular image (e.g., a circle surrounding a proximity portion that is likely to collide, or an arrow pointing to a proximity portion, etc.).

3 (b), the controller 140 displays a recommendation (or recommendation) guideline (that is, a steering direction guideline) capable of avoiding a collision, thereby allowing the driver to adjust the steering direction Thereby avoiding collision with obstacles.

Here, the recommendation guideline does not merely indicate the direction in which the vehicle should travel (the direction toward the destination) nor the lane change information, but rather, the vehicle may proceed according to the adjustment of the steering wheel And the collision area with the obstacle on the predicted path and the collision possibility.

The control unit 140 may detect the steering angle of the vehicle for outputting the recommendation guide line and the auxiliary information, and may detect the steering angle of the vehicle by using the full-width or the back- It is possible to determine the possibility of collision with an obstacle to a direction (e.g., left side right side, etc.).

4 is a flowchart illustrating a method of preventing a vehicle collision using a head-up display according to an exemplary embodiment of the present invention.

As shown in FIG. 4, the control unit 140 displays the vehicle width information of the traveling direction (or the traveling direction) of the vehicle and the surround view image (or the top view image) together with the head-up display 130 (S101).

The surround view image (or top view image) is displayed together with obstacles in the vicinity of the direction in which the vehicle is traveling and lane information of the road on which the vehicle is currently traveling. By displaying the vehicle width information (e.g., front vehicle width information and rear vehicle width information) and the surround view image (or top view image) together as described above, even when the vehicle collision avoiding apparatus according to the present embodiment generates the vehicle collision information, May be aware of the possibility of collision in advance.

As described above, when the vehicle is running while displaying the vehicle width information (for example, front vehicle width information and rear vehicle width information) in the traveling direction (or running direction) of the vehicle and the surrounding view image (or top view image) (S102), the controller 140 displays auxiliary information for preventing collision according to the proximity of the obstacle and the vehicle (S103).

For example, the auxiliary information for preventing the collision according to the proximity of the obstacle and the vehicle is information displayed in order to allow the user to recognize the proximity portion of the obstacle which is likely to collide with the obstacle during running of the vehicle or parking.

The control unit 140 outputs the output timing (e.g., the driver's viewpoint or the observer's viewpoint) of the image (e.g., the top view image or the surround view image) output through the head-up display 130 to the driver It can be changed to the viewpoint or the viewer viewpoint. In addition, the controller 140 may enlarge and display the proximity portion (e.g., the proximity portion with a high possibility of collision) for the display of the auxiliary information.

If the vehicle is approaching an obstacle in the left / right direction, the color information of the corresponding side is displayed differently according to the proximity of the vehicle (e.g., red if the first reference is more than the second reference, Or blue in the case of approaching the third reference or more), and can be displayed by using a specific image such as a circle surrounding the proximity portion likely to collide or an arrow pointing to the proximity portion.

Further, as the auxiliary information, a recommendation (or recommendation) guideline (that is, a steering direction guideline) capable of avoiding a collision may be displayed.

For the sake of reference, the recommendation guidelines do not merely indicate the direction in which the vehicle should travel (direction toward the destination) or the lane change information, Collision area with the obstacle on the predicted path, and the collision possibility with the possible path (that is, the predicted path).

Therefore, the advisory guidelines may display alarm information that warns of a collision with an obstacle on the expected route, and auxiliary information that represents advised steering angle information to avoid collision with an obstacle on the expected route.
