Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is defined by the scope of the claims.

It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms herein include plural forms unless the context clearly dictates otherwise. &Quot; comprises " and / or "comprising" when used in this specification is taken to specify the presence or absence of one or more other components, steps, operations and / Or add-ons.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing a vehicle head unit initializing apparatus according to an embodiment of the present invention.

2, the vehicle head unit initialization apparatus of the present invention includes a unique key management unit 210 for acquiring and storing a unique key of a vehicle and a user, and a head unit control unit 220 for transmitting an initialization signal to the head unit .

More specifically, when an initial head unit user performs service opening to a head unit management center using a unique key, a unique key required for initial opening includes a MAC address of the vehicle head unit, a VIN code of the vehicle, and a user ID And the management center stores the unique key acquired from the user in the unique key management unit 210 when the service is opened.

Thereafter, as the user uses the vehicle head unit, various personal information is necessarily stored in the head unit and the telematics system of the vehicle. To initialize the personal information of the user remaining on the system even after the user ends the service use, The management center sets personal information initialization.

It goes without saying that the initialization setting can be requested not only in the management center but also in the terminal, that is, the head unit of the vehicle. The user can not directly search for and delete the personal information of the terminal when the user forgets the initialization setting in the terminal and relinquishes or lends the vehicle to another person. .

At this stage, the initialization setting request at the center and the terminal is a kind of 'reservation request', which does not mean immediate deletion of personal information at the time of requesting, but means stopping the head unit service by the management center or stopping recording of personal information .

After the initialization setting, a new user who receives the vehicle or uses the head unit of the vehicle continuously uses the unique key to directly connect to the center or requests the use of the service through the terminal to restart the head unit, And compares the ID of the user with the ID of the newly inputted user.

Since the ID of the existing user is different from the ID of the new user after the comparison, the management center determines that the user of the vehicle head unit has been changed and transmits the head unit initialization command to the vehicle head unit.

After that, the head unit of the vehicle receiving the initialization command from the management center automatically initializes all the personal information of the previous user.

3 is a flowchart illustrating a method of initializing a head unit according to an embodiment of the present invention.

As shown in FIG. 3, the head unit of the vehicle first acquires a unique key of a new user to use (S310). If the acquired unique key of the user is different from the unique key of the previously stored user (S320), the head unit deletes the personal use history of the previous user (S330).

Here, the user's personal use history means that personal information stored in the head unit can cause financial and material damage to the user when the user's personal information is leaked. For example, it includes information such as a telephone directory stored in the system, a destination, a recent call list, recent location information, and a failure history.

The head unit of the present invention collects the MAC address and the VIN code through the communication module, and when the user connects to the terminal, the user's ID information is transmitted to the head unit management center. The management center then uses the MAC address, VIN code, and user ID mentioned above as vehicle identification information, and also serves as basic information for providing other services.

When the corresponding terminal service request signal is detected by the ID of another user, the management center checks the same terminal through the MAC address and the VIN code, and determines the change of the user by the user ID. If it is determined that the user has been changed, the management center transmits a signal for controlling the head unit.

The head unit receiving the signal deletes the personal information of the previous user in the terminal. When the deleted personal information is stored in the management center in the form of a database and judges connection to another terminal by the same user ID, It is also possible to provide a personal information delivery service to the terminal.

Hereinafter, the flow of information exchange between the head unit and the management center of the present invention will be described in more detail with reference to FIG.

4 is a flowchart illustrating a procedure for exchanging information between a head unit and a management center according to an embodiment of the present invention.

When the initial terminal is opened, the terminal (head unit) transmits the VIN code, MAC address, and user ID (A) information to the center. The center then stores the acquired information and identifies the terminal and completes the service opening. The user A uses various convenient services provided by the terminal and stops the use of the terminal due to the transfer or sale of the vehicle and sends a reservation signal for initializing the personal information to the center. The management center receives the initialization reservation signal and sets the initialization of the terminal so that connection by a new user is possible. Then, the new user B of the terminal connects to the terminal to use the terminal, and the terminal transmits the ID (B) of the new user to the center and the unique code of the other vehicle to the management center. The management center instructs the head unit to initialize the personal information of the previous user because the ID of the user has changed, the head unit initializes the personal information of the previous user, and transmits an initialization completion signal to the management center.

The management center of the present invention provides a vehicle terminal remote control service by receiving a personal information initialization setting request through a web service provided to a user when the user can not directly delete the personal information stored in the vehicle.

In summary, the present invention provides a method and apparatus for an existing user to initialize personal information stored in a head unit remotely at the time of transfer or sale of a vehicle.

In addition, the present invention identifies a vehicle and a head unit using a unique code of a vehicle and a unique code of a head unit, and automatically deletes a personal use history of a previous user when the ID of a user connected through the head unit is changed, It has the advantage of protecting information.

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention.

Therefore, the embodiments of the present invention are not intended to limit the scope of the present invention, and the scope of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents, which fall within the scope of the present invention as claimed.
