That is, the communication unit 132 communicates with the FOTA server 200 to receive a software file and an update file.

The communication unit 132 may transmit a request signal for providing update information based on a command from the control unit 133 .

The controller 133 may download the firmware update file from the FOTA server 200 ( 300 ), and determine a cache weight for the firmware update file based on difference data included in the downloaded firmware update file ( 310 ).

Also, the controller 133 may determine a cache capacity for the firmware update file based on the determined cache weight ( 320 ), and cache the firmware update file in the cache memory 137 based on the determined cache capacity ( 330 ). . The controller 133 may update at least one software stored in the storage unit 134 using the firmware update file cached in the cache memory 137 ( 340 ).

Specifically, at least one software capable of applying an update to each configuration of the vehicle 1 may be stored in the storage unit 134 . That is, as described above, software for each of the various control units of the vehicle 1 including the electronic control unit 140 is stored.

The controller 133 may request a firmware update file for software update from the FOTA server 200 , and if the update file exists, it may download the update file through the communication unit 132 . That is, a firmware update file (generally known as an update package or delta file) may be downloaded from the FOTA server 200 and cached in the cache memory 137 .

Such a firmware update file may include differential data for performing a partial update of software. The cache memory 137 may store difference data downloaded from the FOTA server 200 , and in this case, the difference data may be cached in the cache memory 137 .

The storage unit 163 may be provided separately from the telematics unit.

The storage unit 163 may store at least one piece of software. Specifically, at least one software capable of applying an update to each configuration of the vehicle 1 may be stored in the storage unit 163 . That is, as described above, software for each of the various control units of the vehicle 1 including the electronic control unit 140 may be stored.

The storage unit 163 includes a flash memory, a ROM (Read Only Memory), an Erasable Programmable Read Only Memory (EPROM), as well as a volatile memory such as S-RAM and D-RAM. It may include a non-volatile memory such as an electrically erasable programmable read only memory (EEPROM).

The cache memory 164 may store difference data downloaded from the FOTA server 200 , and in this case, the difference data may be cached in the cache memory 137 .

Here, the server 200 communicates with the vehicle 1 registered in advance.

The server 200 stores a software file for performing at least one function, an update file for each software, and transmits an update notification message to the vehicle 1 whenever an update file is generated, and the vehicle 1 When a request for providing the update file is received from the vehicle 1 , the update file is transmitted.

The server 200 may provide information on the update file for each software to the vehicle when confirmation of the update file not downloaded from the vehicle 1 is requested.

The server 200 may store information on the downloaded update file for each vehicle, and provide the undownloaded update file to the vehicle based on the stored information on the downloaded update file for each vehicle.

Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium storing instructions executable by a computer. Instructions may be stored in the form of program code, and when executed by a processor, may generate program modules to perform operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

The computer-readable recording medium includes any type of recording medium in which instructions readable by the computer are stored. For example, there may be a read only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.
