The vehicle driving record apparatus 100 of the portable multimedia player 100, a wireless communication network 130, and a service server are shown in FIG. 140, a database 145, a speed sensor 150, and front and rear cameras 160a and 160b.

The vehicle driving record apparatus 100 of the portable multimedia player includes a shock sensor 102, a GPS module 104, a memory 106, a wireless module 108, a controller 110, a navigation module 112, and an image processing module. 114, a storage medium 116, an interface 118, and a display 120.

In the present invention, for the convenience of description, the shock sensor 102 is described as being mounted on the portable multimedia player, for example, but may also be attached to the vehicle.

The shock sensor 102 is driven when an impact greater than or equal to a threshold is applied to the vehicle to generate an interrupt signal, and outputs the generated interrupt signal to the controller 110.

In addition, the shock sensor 102 is connected to the speed detecting unit 150 attached to the vehicle, for example, when the vehicle is driven at a speed higher than a preset speed while the vehicle is driven at a predetermined speed or more, the shock sensor 102 is driven and interrupted. A signal is generated and the generated interrupt signal is output to the controller 110.

The GPS module 104 communicates with the GPS satellites to receive driving record data based on the current position of the vehicle. Here, the driving record data may be a driving speed of the vehicle, time information, accident point coordinate data of the vehicle through GPS satellite trajectory when an accident occurs.

The memory 106 is a non-volatile memory in which driving record data received by the GPS module 104 is stored under the control of the controller 110, for example, a flash memory.

The wireless module 108 is driven by an optional connection control signal generated from the controller 110 to connect the driving recorder 100 of the portable multimedia player to the service server 140 through the wireless communication network 130, and the memory The driving record data stored in the 106 or the storage medium 116 is received from the controller 110 and provided to the service server 140.

An example of the wireless module 108 is High Speed Downlink Packet Access (HSDPA).

The control unit 110 controls the driving recording apparatus 100 of the portable multimedia player as a whole, and in particular, in response to the interrupt signal generated by the shock sensor 102 for the present invention, the connection control signal is transmitted to the wireless module 108. By outputting, the wireless module 108 is driven. Accordingly, the driving record data stored in the memory 106 is stored in the database 145 interworking with the service server 140 through the wireless module 108, and the recent driving record data stored in the storage medium 116 is optionally stored. It is stored in the database 145 interworking with the service server 140 via the wireless module 108.

In addition, the controller 110 stores the driving record data stored in the memory 106 in the storage medium 116 when the interrupt signal is not received from the shock sensor 102 for a predetermined time, and then stores the driving data stored in the memory 106. By deleting the write data, the memory 106 is refreshed.

As the interrupt signal is received from the shock sensor 102, the controller 110 selectively drives the interface 118 to receive photographic data captured by the front and rear cameras 160a and 160b connected to the interface 118, and the storage medium. 116 or provide to service server 140 via wireless module 108.

The navigation module 112 is connected to the storage medium 116 to perform vehicle navigation or telematics terminal information processing.

The image processing module 114 performs a format conversion for configuring an image signal together with decoding such as decompression and decompression of multimedia data stored in the storage medium 116 so as to be displayed on the display unit 120, for example, an LCD. Do this.

The storage medium 116 stores various multimedia data, programs and data for providing a navigation function, and in particular, driving record data stored in the memory 106 by the controller 110.

The interface 118 is a means for connecting to an external device, for example, the front and rear cameras 160a and 160b. In particular, the interface 118 may include a wired interface such as IEEE1394, USB, or a wireless interface such as Bluetooth or an infrared communication module. Can be.

Here, the interface 118 is driven under the control of the controller 110 to provide the controller 110 with front and rear photograph data of the vehicle photographed by the front and rear cameras 160a and 160b.

The service server 140 stores the photo data or the driving record data transmitted through the wireless communication network 130 in the database 145.

The speed detector 150 is a speed sensor mounted on the vehicle, and detects the driving speed of the vehicle and provides the shock sensor 102.

A process of storing the driving record data by operating the driving recorder of the portable multimedia player having the above configuration will be described with reference to FIG. 2.

Referring to FIG. 2, when the vehicle starts to drive after the driving recording apparatus 100 of the portable multimedia player is installed in the vehicle (S200), the controller 110 drives the navigation module 112 and the GPS module 104. By activating the vehicle navigation function and the telematics function, driving record data received by the GPS module 104 is stored in the memory 106 (S202 and S204).

Then, the controller 110 determines whether an interrupt signal is received from the shock sensor 102 for a preset time (S206). That is, the shock sensor 102 generates an interrupt signal when a speed more than a predetermined value is sensed from the speed detecting unit 150, for example, when the vehicle travels at a speed greater than or equal to a preset value or when an impact greater than or equal to a threshold is applied to the vehicle.

As a result of the determination in step S206, when the interrupt signal is not received from the shock sensor 102 even after the preset time elapses, the controller 110 stores the driving record data stored in the memory 106 in the storage medium 116. (S208), the driving record data stored in the memory 106 is deleted (S210).

As a result of the determination in step S206, when an interrupt signal is received from the shock detection sensor 102 in a state where a preset time has not elapsed, the controller 110 generates a connection control signal to drive the wireless module 108 to store the memory 106. The driving record data stored in the driving record data is provided to the service server 140 through the wireless module 108 and the wireless communication network 130, and the service server 140 records the driving record provided from the driving recording apparatus 100 of the portable multimedia player. The data is stored in the database 145 (S212, S214).

When providing the driving record data to the service server 140, the controller 110 drives the interface 118 to record the front and rear photograph data of the vehicle photographed from the front and rear cameras 160a and 160b connected to the interface 118. The data is transmitted to the service server 140 or the front and rear picture data are stored in the storage medium 116.

In addition, the controller 110 retrieves the recently stored driving record data among the driving record data stored in the storage medium 116 and provides the same to the service server 140 through the wireless module 108, thereby providing the service server 140. In the database 145 linked to the

According to the present invention, the driving record data received through the GPS module 104 while driving the vehicle is stored in the memory 106, and when the accident occurs, the driving record data stored in the memory 106 through the wireless module 108 By providing the service server 140 and storing it in the database 145, it is possible to prevent the loss of the driving record data when an accident occurs.

The present invention is not limited to the above-described preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the invention as claimed in the claims. Such changes will fall within the scope of the claims.

As described above, the present invention stores the driving record data received through the GPS module during driving of the vehicle in the memory and then stores the driving record data stored in the memory to the service server through the wireless module in the database when an accident occurs. Therefore, it is possible to prevent the loss of driving record data in the event of an accident.
