BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle driving record apparatus, and more particularly, to an apparatus for recording an image and location information in order to make it easy to identify who caused an accident by any process when an accident occurs while driving a vehicle.

Currently, the number of cars owned is increasing so that more than one car is owned per household, and the number of car accidents continues to increase with the increase in the absolute number of cars. However, in the case of an actual car accident, it is not easy to calculate who caused the accident and its error rate.However, even if the site is well preserved or there is a photograph of the site, these data are available after the accident. It is only the data obtained, and more information is often needed to calculate the error because it is not known what happened during the accident.

However, the conventional invention simply detects the occurrence of an accident by using a shock sensor or inertia, and at this time, a method of immediately recording a situation or recording a driving situation for a long time on a video tape has been proposed. The situation after suffering was not much different from the photographing after the accident, so it was not enough to be a data for understanding the situation properly, and it was impossible to grasp the progress of the accident because there was no information on the operation status of the vehicle.

To this end, it was proposed to install a black box inside the car and add a device that continuously records data such as the speed of the vehicle, but since the data stored in the black box is limited to the data that can be obtained inside the car, Except that they were running at a speed, it was not enough to fully explain the situation before and after the accident.

In order to overcome the drawbacks described above, the present invention provides an apparatus for recording the driving process of the vehicle as an image data while providing information on the driving of the vehicle so that the situation before and after the accident can be recorded. do.

In order to achieve the above object, the present invention provides a vehicle driving record apparatus, wherein the vehicle driving record apparatus includes: a camera unit for recording an image of the front of the vehicle;

A GPS unit for receiving a GPS satellite signal to obtain information such as a location signal, a speed, and a driving direction of the vehicle;

An input / output unit for receiving signals from the camera unit and the GPS unit, converting the signals into digital signals, and transmitting these signals to an external device as necessary;

A memory unit for storing a data signal received through the input / output unit;

It may include a control unit for controlling the operation of the camera unit, GPS unit, input / output unit, memory unit and the transmission of data between the device.

The vehicle may further include a sensor unit including one or more sensors for detecting an impact in order to detect that the vehicle has an accident.

The memory unit may be divided into one or more areas, and the vehicle driving information may be stored in the area, but when all of the memories are in use, the memory unit may delete the first memory area stored in chronological order and store the vehicle driving information again thereon.

It may further include an auxiliary camera facing upward to photograph the state of the traffic light.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. 1 is a block diagram showing the configuration of a vehicle driving record apparatus according to the present invention. As shown in the block diagram, the video camera unit 11 installed in any part of the vehicle and the GPS unit 12 generating a signal related to the driving of the vehicle from the satellite GPS and the video are generated. Receives an image signal input from the camera and GPS, converts it into a digital signal, sends it to the control unit along with the signal from the GPS, and sends / outputs the data converted into a digital signal to the input / output unit 13 for transmitting the data to the outside when the user requests it. The memory 14 for storing, the input / output unit, the control unit 15 for controlling the transmission of data between the memory and the impact sensor unit 16 for identifying whether there is an accident in the vehicle.

The video camera unit 11 may be buried or attached to a place where the visibility of the front of the vehicle can be secured, such as inside the vehicle or the outside of the bumper, to be mounted on the windshield or mounted on the dashboard. It may be. The video camera used should have enough resolution to check the license plate of the vehicle from far away in front of the vehicle. Recently, the compact camera has a sufficient resolution but its size is very small. You can also attach some space to the GPS.

In addition, the video taken by the video camera unit records the video automatically when the vehicle starts running, not at the moment of an accident or at any point of time like the existing products. Continue shooting while facing the direction. In this case, when using a tape or other storage medium, there may be a limit in the storage space, but in the present invention, the image is converted into digital data and the storage space is divided into several storage areas, so that the time sequence is the fastest when the storage space becomes full. It will delete the contents of the place and save it again. Therefore, the amount of memory for storage does not have to be excessive and efficient use is possible even if the size of the memory is small.

If necessary, the video camera unit may be composed of one or more cameras, and may be attached in each direction because an accident may occur not only in the front but also in the rear and the side. However, the front camera is coupled to a device such as GPS, but other cameras may be attached to other parts of the car.

In addition, it is also important about the operation of the car in the event of an accident, but it is very important to determine whether the car's progress signal was faulty. If the camera is pointing forward to the traffic light, there may not be a problem, but if the traffic light is not taken at the time of the accident, it may not help in handling the accident. Therefore, a separate camera should be provided so that the camera takes a more upward direction than the front so that a traffic light can always enter the field of view. However, since the camera takes only signals of a traffic light, the camera can have a resolution that can determine the shape and color of the traffic light well, thereby reducing the memory usage.

GPS unit is a device that finds the current position by using a few satellites orbiting the earth. Using GPS, you can get information about the position coordinates and speed of the car without attaching a separate device. Due to its wide spread, it is possible to receive time-based location information and speed information from the device, and it is also possible to produce a combination of GPS / navigation and the device according to the present invention.

The input / output unit receives a signal from the camera unit and the GPS unit and transmits the signal to the memory unit and the control unit, and includes a port for transmitting the information related to the driving record to the outside when the user wants to record the information to an external recording device. In addition, since the information from the camera unit is an analog signal, it is also possible to convert the information into a digital signal.

The memory unit stores position signals, speeds, and image signals from the input / output unit according to time. When data enters the memory unit, the time sequence is first deleted and the data is recorded again. If you erase and write every minute, processing speed will slow down. Divide the memory into several spaces with a certain size, and when the above space fills up, erase all the data in the space where the time sequence is fast to secure the free space. Done.

The sensor unit detects the presence of external shock and transmits it to the control unit. If an accident occurs, the sensor unit continues to record the image only for a predetermined time after the accident occurs. However, after the accident, there may be another accident in the accident handling process, so after the shock occurs, the sensor continues to record the image after the sensor detects it, but the memory space where the first accident occurred is not erased. Keep recording only until the moment it doesn't.

The control unit controls the operation of each unit and the transmission of data between the input and output unit, the GPS unit, the camera unit, the sensor unit, the memory unit.

2 is a flowchart showing the operation of the driving of the vehicle driving record apparatus according to the present invention. When the vehicle starts to drive, the camera takes a picture of the front of the vehicle and the GPS also receives the location information of the vehicle and records it in memory. When the storage space is divided into multiple spaces, the memory unit deletes the contents of the first recorded storage space and records the data again to store the information while the vehicle is running. When the vehicle receives a signal that an impact has been applied, the controller detects that an accident has occurred and records the video information and location information only for a certain time from the time of the accident to preserve the video information and location information. Help to deal with the incident.

3 is a view showing an embodiment of a vehicle driving record apparatus according to the present invention. LCD panel is attached to the front of the driving recorder of the figure and GPS is built in, so it is usually used for navigation for road guidance, but the back of the LCD panel has a built-in video camera to always capture the situation in the front. do. The sensor unit is mounted on the vehicle to detect the shock, and may be transmitted wirelessly such a shock signal.

Figure 4 is also a view showing an embodiment of the vehicle driving recorder and the figure shows a view from the back and the camera is not the center of the back of the driving recorder so that the camera is not covered when the recorder is mounted on the vehicle glass, etc. It is better to be installed in a biased manner. The camera taking the traffic light does not matter where it is installed unless it is obscured from above.

According to the invention as described above has the effect of fully recording the information on the operation of the vehicle to enable reliable accident handling even in the event of an accident.
