In order to clearly describe the present invention, parts irrelevant to the description are omitted, and like reference numerals designate like elements throughout the specification.

An upgrade system and method of an AVN (Audio / Video / Navigation) head unit and ECUs using Bluetooth according to an embodiment of the present invention will be described with reference to FIGS.

1 is a view showing the configuration of an AVN head unit that can be upgraded through mobile communication according to the present invention, Figure 2 is a method for upgrading the AVN head unit and ECU using mobile communication in one embodiment of the present invention It is a flowchart for explanation.

As shown in FIG. 1, the upgrade system of AVN head units and ECUs using Bluetooth includes AVN, a data center 100 that is a manufacturer server of ECUs (Electronic Control Units), a Bluetooth mobile communication terminal 200, and an AVN head. The unit 300 is composed of ECUs 400 connected to a controller area network (CAN).

The data center 100 receives and stores new upgrade data by an administrator, and receives the download request from the Bluetooth mobile communication terminal 200 and transmits the data to the Bluetooth mobile communication terminal 200 through the mobile communication network.

The Bluetooth mobile communication terminal 200 has a built-in Bluetooth module for performing data communication according to the Bluetooth protocol, performs data communication according to the data center 100 and the wireless Internet protocol, and downloads upgrade data. The downloaded data is transmitted to the AVN head unit 300 through the Bluetooth module.

The AVN head unit 300 includes a Bluetooth module 310, a Bluetooth processor 320, an OS processor 330, an application processor 340, and a CAN interface 350.

The Bluetooth module 310 performs data communication with a mobile communication terminal in which the Bluetooth module is embedded, and the Bluetooth processing unit 320 stores update data received from the Bluetooth mobile communication terminal 200 through the Bluetooth module 310.
