BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an obstacle display device and a display method using a media playback device for a vehicle. More specifically, the present invention relates to a vehicle mounted in a vehicle without providing a separate display device for indicating whether an obstacle exists around a conventional vehicle. The present invention relates to an obstacle display apparatus and a display method using a media playback apparatus for an automobile informing the presence or absence of an obstacle or an approaching object around a vehicle using a display unit and a speaker of a media playback apparatus.

As the number of cars increases, most cities suffer severe parking shortages, which is the main reason for the narrowing of parking spaces.

Therefore, if you park in a narrow space, you may park with a few dozen round trips, except for a very experienced driver, which also causes a lot of damage due to collision with an obstacle or collision with another adjacent car. .

Also, in the case of vans, there are many people who attach a separate mirror to the front of the car to check the distance, but in the case of the rear mirror, it is mounted inside and you can see the traffic situation behind the car through the rear mirror. It occupies a large part of the field of view of the rearview mirror mounted so that it is an obstacle to driving.

In order to improve these disadvantages, a technology for attaching a sensing sensor to identify obstacles in the rear of the vehicle and checking the distance to the obstacles in the rear is developed and applied to high-end vehicles.

The detection sensor is mainly implemented using an ultrasonic sensor.

The ultrasonic sensor uses an echo phenomenon of sound waves, generates ultrasonic waves, receives ultrasonic waves reflected from obstacles, and calculates time differences to measure distances to the obstacles. In addition, the sensor detects the distance using electromagnetic waves, but it is difficult to detect the distance when measuring the distance to a nearby object because of the nature of the electromagnetic wave. The disadvantage is that.

Therefore, a sensor using an ultrasonic wave is mainly used as a sensor mounted on an automobile.

Meanwhile, when a distance from an obstacle or the like is detected by the detection sensor, a separate display device is required to notify the driver of the distance.

For example, when an obstacle is detected at the rear, a warning sound is output, or a camera is mounted at the rear of the vehicle, and the image taken is displayed on the screen through a display device in the vehicle, or such an audio or visual warning is used. do.

In this case, if the distance to the obstacle is close, the frequency of occurrence of the warning sound is also made faster, thereby indicating that the risk of collision with the obstacle is high.

However, there is a disadvantage in that a separate display device must be included in a vehicle in order to perform the aforementioned distance sensing.

Hereinafter, an obstacle display device and a display method using the vehicle media player of the present invention will be described in more detail with reference to the accompanying drawings.

1 is an exemplary block diagram of an obstacle display apparatus using an in-vehicle media playback apparatus according to the present invention.

As illustrated, the obstacle display apparatus using the media playback apparatus for a vehicle according to the present invention includes one or more distance sensing sensors 100a and 100b, a warning data generator 200, and a display data generator 300. In addition, it may further include a warning sound generating unit 400, although not shown may further include a power control unit.

The distance detection sensors 100a and 100b are disposed in the vehicle to generate distance detection data with respect to the obstacle.

For example, since the presence of an obstacle behind the vehicle is most important to the driver, the distance detecting sensors 100a and 100b may be disposed at the rear of the vehicle. One or more distance sensing sensors 100a and 100b may be provided to extract direction information from an obstacle. In addition, the distance sensor may be arranged not only for the rear but also for detecting obstacles on the side, for example.

The warning data generation unit 200 receives distance detection data from the distance detection sensors 100a and 100b, and outputs a value that is less than or equal to a predetermined threshold distance among the distance detection data and direction information of an obstacle corresponding to the distance detection data that is less than or equal to the threshold distance. Generate warning data to include. The distance detecting sensors 100a and 100b and the warning data generating unit 200 may be configured to transmit distance sensing data through, for example, a wireless communication connection.

The threshold distance is, for example, a minimum value for informing the driver of the presence of an obstacle. For example, if the obstacle is within 1.6 m, the threshold distance is set to 1.6 m.

In addition, the direction information of the obstacle may be generated, for example, corresponding to a portion where the distance sensing sensors 100a and 100b are disposed.

For example, when detecting a distance to an obstacle with respect to a rear portion of the vehicle, direction information may be generated to the left side of the rear side, the center of the rear side, the right side of the rear side, and the like.

The warning data includes direction information of these obstacles and information about the distance to the obstacles.

The display data generating unit 300 generates display data to be displayed on the display unit of the vehicle media player based on the warning data generated by the warning data generating unit 200.

That is, the conventional obstacle warning device is provided with a separate display device to display the presence of the obstacle.

However, the display data generation unit 300 of the present invention displays the distance and the direction of the obstacle using a display unit such as an LCD, which is arranged for displaying various kinds of information on the car media player, for example, car audio, mounted in the vehicle. It is composed.

Such display data is variably generated according to the distance to the obstacle or the direction of the obstacle.

For example, when the distance to the obstacle is 1.6 m or more, display data is generated so that no display is performed or a reverse warning message is output.

For example, when the distance to the obstacle is between 1.5 m and 1.6 m, and the obstacle is present on the left side of the rear surface, display data is generated to be displayed as "L1.5 R" and displayed on the LCD of the car audio.

For example, when the distance to the obstacle is between 0.30 m and 0.39 m, and the obstacle is present in the center of the rear surface, the display data is generated to be displayed as "L0.3 R0.3" and displayed on the LCD of the car audio.

In this manner, the presence, direction, and distance of obstacles can be simply displayed using a display unit of a conventional vehicle media player without having a separate display device.

In addition, the display data generating unit 300 may be notified of the presence of an obstacle, and at the same time, a warning sound may be output through a speaker of the vehicle media player.

To this end, the obstacle display device using the vehicle media reproducing apparatus according to the present invention may further include a warning sound generator 400.

That is, a plurality of speakers are arranged in the vehicle to reproduce sound output from the media playback apparatus for a vehicle.

For example, such a speaker may be disposed on the front left side, front right side, rear left side, rear right side, or the like of the vehicle.

The warning sound generating unit 400 generates a warning sound signal to be output through the speaker of the vehicle media player based on the warning data.

In this case, the warning sound signal may be generated by adjusting the occurrence frequency or volume based on the distance from the obstacle.

In other words, when the distance to the obstacle is close, the volume is generated loud or very fast.

In addition, the warning sound signal may be generated to control the plurality of speakers to recognize the direction of the obstacle.

In other words, if the obstacle is detected in the rear of the vehicle, if there is an obstacle in the center part of the rear, the speaker is controlled to output the warning sound signal at the same volume from the speakers arranged at the rear left and rear right at the same time. In the case where an obstacle exists in the rear left portion, the speaker may be controlled to output a warning sound signal only to the speaker disposed at the rear left side.

In addition, the obstacle display device using the media reproducing apparatus for a vehicle according to the present invention can be used, for example, when the vehicle moves backward or moves for parking.

In this case, the obstacle display apparatus using the vehicle media player according to the present invention outputs information such as the direction and distance of the obstacle by using the display unit or the speaker of the vehicle media player.

Therefore, there is a disadvantage in that an efficient obstacle warning is difficult when the power of the media reproducing apparatus for the vehicle is turned off when the vehicle is reversed or when moving for parking.

For this case, the obstacle display device using the vehicle media player according to the present invention may further include a power controller (not shown).

That is, when a warning about an obstacle is required, the power control unit may control the power of the vehicle media player for displaying the above-described display data or outputting a warning sound signal.

In this case, it is preferable that the power control unit controls the power of the media player for the vehicle when there is an obstacle only when the vehicle is not stopped, that is, when the vehicle is in a reverse state, while parking, or while driving. And display of data or output of a warning acoustic signal.

The warning data generating unit 200 or the display data generating unit 300 or the warning sound generating unit 400 or the power control unit (not shown) may be efficiently implemented to reduce the manufacturing cost by integrating the vehicle media reproducing apparatus. will be.

Through such a configuration, it is possible to simply display information such as the presence and distance of obstacles on the display unit of the vehicle media player.

2 is an exemplary flowchart of an obstacle display method using a media playback apparatus for a vehicle according to the present invention.

First, distance sensing data is received from at least one distance sensing sensor disposed in the vehicle to generate distance sensing data with an obstacle (S110).

For example, since the presence of an obstacle behind the vehicle is most important for the driver, a distance sensor may be disposed at the rear of the vehicle to generate distance detection data. In addition, at least one distance sensor may be provided to extract direction information from the obstacle. In addition, the distance sensor may be arranged not only for the rear but also for detecting obstacles on the side, for example.

Subsequently, warning data including a value less than or equal to a predetermined threshold distance and direction information of an obstacle corresponding to the distance sensing data less than or equal to the threshold distance is generated from the distance sensing data received in step S110 (S120).

The threshold distance is, for example, a minimum value for informing the driver of the presence of an obstacle. For example, if the obstacle is within 1.6 m, the threshold distance is set to 1.6 m.

In addition, the direction information of the obstacle may be generated corresponding to, for example, a portion where the distance sensor is disposed.

For example, when detecting a distance from an obstacle with respect to a rear portion of the vehicle, the direction information of the obstacle may be generated from respective distance sensing sensors disposed on the left side of the rear side, the center of the rear side, and the right side of the rear side.

The warning data includes direction information of these obstacles and information about the distance to the obstacles.

Thereafter, display data to be displayed on the display unit of the vehicle media playback apparatus is generated based on the warning data generated in step S120 (S130).

The display data is configured to display the distance and the direction to the obstacle, and is a signal form suitable for displaying on a display unit for an automobile media player such as an LCD.

In addition, it is also possible to display the presence of an obstacle using an LCD or the like and to output a warning sound through the speaker of the vehicle media player.

That is, a plurality of speakers are arranged in the vehicle to reproduce sound output from the media playback apparatus for a vehicle. For example, such a speaker may be disposed on the front left side, front right side, rear left side, rear right side, or the like of the vehicle. In the case of using such a speaker, information such as the presence of an obstacle, a distance, and a direction may be audibly provided to the driver.

To this end, a warning sound signal to be output through the speaker of the vehicle media player is generated based on the warning data generated in step S120 (S140).

In this case, the warning sound signal may be generated by adjusting the occurrence frequency or volume based on the distance from the obstacle. In other words, when the distance to the obstacle is close, the volume is generated loud or very fast.

In addition, the warning sound signal may be generated to control the plurality of speakers to recognize the direction of the obstacle. That is, if the obstacle is detected in the rear of the vehicle, if there is an obstacle in the rear center portion, a warning sound signal is generated so that the same volume is output from the speakers arranged at the rear left and rear right at the same time. If there is an obstacle in the left part of the warning sound signal can be generated to be output only from the speaker disposed on the left rear.

In addition, the obstacle display method using the media reproducing apparatus for a vehicle according to the present invention can be used, for example, when the vehicle moves backward or moves for parking.

In this case, the obstacle display method using the vehicle media player according to the present invention outputs information such as the direction and distance of the obstacle by using the display unit or the speaker of the vehicle media player.

Therefore, there is a disadvantage in that an efficient obstacle warning is difficult when the power of the media reproducing apparatus for the vehicle is turned off when the vehicle is reversed or when moving for parking.

For this case, the method may further include controlling power of the vehicle media reproducing apparatus (not shown) for displaying the display data generated in step S130 or outputting the warning sound signal generated in step S140.

This power control step is preferably displayed when there is an obstacle by controlling the power of the media playback device for the vehicle only when the vehicle is not stationary, i.e., when the vehicle is in a reverse state, while parking, or while driving. And display of data or output of a warning acoustic signal.

Through such a configuration, it is possible to simply display information such as the presence and distance of obstacles on the display unit of the vehicle media player.

Although the configuration of the present invention has been described in detail, these are merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. This will be possible. Therefore, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments.
