Description

Parking impact event video selection storage method of black box for vehicles}

The present invention relates to a method for selecting and storing a parking shock event image of a vehicle black box, which enables to selectively store an impact event image in a parking mode of the vehicle black box.

In general, a vehicle black box is recognized as an image storage device for recording vehicle accident images, which constitutes two channels with front and rear cameras, or four channels with front and rear and left and right cameras, and the two channels are Most of them are applied to small vehicles, and 4 channels are applied to large vehicles (eg, buses, etc.).

A conventional black box for a vehicle stores an image according to the impact (hereinafter referred to as a 'shock event image') when an impact is applied to the vehicle in the driving mode or the parking mode, and the impact event image is the time before and after the impact time. It includes video.

That is, in the vehicle black box, not only a collision accident with a person or a vehicle, but also an impact greater than a set standard value (eg, vibration due to opening and closing of a vehicle door or vibration when another vehicle passes adjacent to the vehicle) is transmitted to the vehicle. When the vibration is transmitted, the vibration is recognized as an impact, and the before and after images are saved based on the time when the vibration is transmitted.

However, in the conventional vehicle black box, when the shock event image is stored in the parking mode, the shock event image contains the driver's action (eg, opening and closing of the vehicle door) and vibration generated while another vehicle passes by even when the driver is located close to the vehicle. After judging , it is necessarily stored as a shock event image. Accordingly, in the prior art, when a driver wants to search for a stored shock event image according to an accident through the screen of a PC or a black box, it is stored by the action of the vehicle driver. It was not possible to distinguish the shock event images, and accordingly, it was inconvenient that a considerable amount of time was required to search only the specific shock event images according to the accident.

The problem to be solved by the present invention is that, when the black box is converted to the parking mode and the image of the shock event is stored, the driver is near the vehicle or the image of the shock event caused by the driver's action is excluded, and the driver can recognize while leaving the vehicle. An object of the present invention is to provide a method for selecting and storing a parking shock event image of a vehicle black box that can selectively store only an impossible shock event image.

The method for selecting and storing a parking shock event image of a vehicle black box, which is a means of solving the problems of the present invention, is (a) communication within the black box terminal when the black box terminal having the first communication module is switched to the parking mode from the stop of the vehicle checking whether the module and the second communication module in the driver's terminal are available for communication; (b) if the first communication module in the black box terminal and the second communication module in the driver's terminal are within the communicable area from the check in step (a), excluding the image storage of the impact event due to the driver's action; and, (c) if the first communication module in the black box terminal and the second communication module in the driver's terminal are out of the communicable area from the check in step (a), storing all images according to the impact event; will include

In addition, the first communication module in the black box terminal and the second communication module in the driver terminal are Bluetooth communication modules for short-range wireless communication.

In addition, in step (b), when the first and second communication modules are located within the communication available area, the image of the impact event stored in the black box terminal by the step (c) is transmitted to the driver terminal. ; will further include

In addition, the shock event caused by the driver's action in step (b) is a vibration shock according to the opening and closing of the vehicle door.

In addition, the image of the shock event that is excluded from storage in step (b) further includes a vibration shock generated by another vehicle driving at a close distance to the driver's vehicle.

As described above, in the present invention, when the black box is switched to the parking mode and the shock event image is stored, the driver is near the vehicle or the shock event image due to the driver's action is excluded, and the driver is out of the vehicle and the shock event cannot be recognized. It is to selectively store only the images, and through this, when the driver searches for the stored shock event images according to the accident through the screen of the PC or black box, the search is performed quickly and it is expected to reduce the time for identifying the cause of the accident. it can be

1 is a schematic block diagram for implementing a method for selecting and storing a parking impact event image of a vehicle black box according to an embodiment of the present invention, and FIG. 2 is an embodiment of the present invention. A control flow diagram showing the method is shown.

1 and 2 , the method for selecting and storing a parking shock event image of a vehicle black box according to an embodiment of the present invention includes a camera 11 , a memory 12 , and a control unit 13 in front of a vehicle or After configuring the first communication module 14 capable of short-range wireless communication in the black box terminal 10 at the rear of the vehicle, the driver terminal (eg, smartphone) 20 of the vehicle in which the black box terminal 10 is installed The second communication module 21 capable of short-range wireless communication is to selectively store the shock event image according to being located in the communicationable area with the first communication module 14 or out of the communicationable area, ( Steps a), (b), and (c) will proceed.

In step (a), when the black box terminal 10 having the first communication module 14 is switched to the parking mode from the stop of the vehicle, the first communication module 14 in the black box terminal 10 and the second communication module 21 in the driver terminal 20 is to check whether the communication is possible area.

That is, in step (a), the first communication module 14 in the black box terminal 10 and the second communication module 21 in the driver terminal 20 are located in the short-range wireless communication area or short-range wireless communication. It is a check to determine if it is out of the realm.

For example, if the driver parks the vehicle and does not deviate from the short-range wireless communication area of Bluetooth adjacent to the inside of the vehicle or the outside of the vehicle, the first and second communication modules 14 and 21 are capable of short-range wireless communication, When the driver leaves the short-range wireless communication area of Bluetooth while moving away from the vehicle, the first and second communication modules 14 and 21 are unable to perform short-range wireless communication.

In step (b), from the check in step (a), if the first communication module 140 in the black box terminal 10 and the second communication module 21 in the driver terminal 20 are within the communication range, the It is to exclude the image storage of the impact event due to the driver's action through the camera 11 .

That is, in step (b), the image of the impact event that occurs when the driver opens and closes the door of the parked vehicle in a state where the first and second communication modules 14 and 21 are located within the short-range wireless communication area is Even if it is photographed by the camera 11, it is excluded from storing it in the memory 12, which is an impact event that occurs while a driver adjacent to the vehicle opens and closes the vehicle door, and the driver is aware of this. Accordingly, the image information of the impact event captured by the camera 11 is not stored in the memory 12 in the black box terminal 10 .

Here, in the step (b), the image of the impact event according to the driver's action captured through the camera 11 was not stored in the memory 12, but in addition, the driver is located around the vehicle and the first And in a state where short-range wireless communication of the second communication modules 14 and 21 is possible, an impact that can be recognized by the driver, that is, an image of an impact event caused by vibration generated by driving of another vehicle at a distance close to the driver's vehicle is displayed by the camera ( 11), this may also not be stored in the memory 12, because the driver recognizes vibrations caused by the driving of other vehicles while being located around the vehicle.

In step (c), from the check in step (a), the first communication module 14 in the black box terminal 10 and the second communication module 21 in the driver terminal 20 are out of the communication range and in a short distance. When wireless communication is not made at all, when a direct shock is applied to the driver's vehicle or when vibration is transmitted, the image of the shock event according to the shock or vibration is captured by the camera 11 and then stored in the memory 12 to save it.

That is, in the selective storage of the shock event image according to the embodiment of the present invention, when the driver's action or a vibration recognizable by the driver is generated, the controller 13 in the black box terminal 10 controls the camera ( 11) is not stored in the memory 12, but when a shock or vibration that the driver cannot perceive is applied to or transmitted to the vehicle as the driver moves away from the vehicle, the The control unit 13 stores all the shock event images captured by the camera 11 in the memory 12 .

Then, the driver can quickly search only the shock event image stored in the memory 12 in a state in which the driver is not aware, thereby reducing the time required to determine the cause of the accident.

On the other hand, as the driver approaches the vehicle, the second communication module 21 in the driver terminal 20 carried by the driver and the first communication module 14 in the black box terminal 10 installed in the vehicle perform short-range wireless communication. When this is possible, the control unit 13 in the black box terminal 10 may transmit an image of an impact event that the driver did not recognize, stored in the memory 12, to the driver terminal 20, and accordingly, the driver While checking the image of the shock event through the driver terminal 20 , it is possible to easily identify the cause of the accident according to the image of the shock event.

In the above, the technical idea of the parking impact event image selection and storage method of the black box for a vehicle of the present invention has been described with the accompanying drawings, but this is an exemplary description of the best embodiment of the present invention and does not limit the present invention.

Therefore, the present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the present invention as claimed in the claims. It is, of course, possible that such modifications are intended to be within the scope of the appended claims.
