Abstract

A method for controlling a Bluetooth connection includes connecting a terminal with a vehicle through a Bluetooth connection. The Bluetooth connection is disconnected according to a disconnection request of the terminal. It is automatically determined whether a Bluetooth communication of the terminal is available or not in the vehicle, when the disconnection of the Bluetooth connection is detected. The Bluetooth connection is requested again from the vehicle to the terminal, when the response indicating the Bluetooth communication is available is received from the terminal. The vehicle and the terminal are connected by requesting the Bluetooth connection again.

Claims

1. A method for controlling a Bluetooth connection, comprising steps of:

connecting a terminal with a vehicle through a Bluetooth connection;

disconnecting the Bluetooth connection according to a disconnection request of the terminal;

automatically determining whether a Bluetooth communication of the terminal is available or not in the vehicle, when the disconnection of the Bluetooth connection is detected;

requesting the Bluetooth connection again from the vehicle to the terminal, when receiving from the terminal a response indicating the Bluetooth communication is available; and

connecting the vehicle and the terminal by requesting the Bluetooth connection again.

2. A method for controlling a Bluetooth connection according to claim 1, wherein the step of automatically determining whether a Bluetooth communication of the terminal is available or not includes:

determining whether the Bluetooth communication is available or not to a previous terminal which has been connected immediately before the step of disconnecting the Bluetooth connection, and

when the Bluetooth connection between the previous terminal and the vehicle is not established, determining whether the Bluetooth communication is available from a highest priority terminal of terminals registered in a terminal registration mode for the Bluetooth connection of the vehicle in order of priority.

3. A method for controlling a Bluetooth connection, comprising steps of:

manually requesting, by a user of a vehicle, a Bluetooth connection of the vehicle and a terminal;

disconnecting the Bluetooth connection of the vehicle and the terminal when the requested Bluetooth connection is not established;

automatically determining whether a Bluetooth communication of the terminal is available or not in the vehicle, when the Bluetooth connection is detected;

requesting the Bluetooth connection again from the vehicle to the terminal, when receiving, from the terminal, a response indicating the Bluetooth communication is available; and

connecting the vehicle and the terminal by requesting the Bluetooth connection again.

4. A method for controlling a Bluetooth connection according to claim 3, wherein the step of automatically determining whether a Bluetooth communication of the terminal is available or not includes:

determining whether the Bluetooth communication is available or not to a previous terminal which has been connected immediately before the step of disconnecting the Bluetooth connection, and

when the Bluetooth connection between the previous terminal and the vehicle is not established, determining whether the Bluetooth communication is available from a highest priority terminal of terminals registered in a terminal registration mode for the Bluetooth connection of the vehicle in order of priority.

5. A method for controlling a Bluetooth connection, comprising steps of:

connecting a terminal with a vehicle through a Bluetooth connection;

changing a multimedia mode of the vehicle from a Bluetooth connection mode to a radio receiving mode or a terminal registration mode for the Bluetooth connection;

disconnecting the Bluetooth connection according to the change;

automatically determining whether a Bluetooth communication of the terminal is available or not in the vehicle, when the disconnection of the Bluetooth connection is detected;

requesting the Bluetooth connection again from the vehicle to the terminal, when receiving from the terminal a response indicating that the Bluetooth communication is available; and

connecting the vehicle and the terminal by requesting the Bluetooth connection again.

6. A method for controlling a Bluetooth connection according to claim 5, wherein the step of automatically determining whether a Bluetooth communication of the terminal is available or not includes:

determining whether the Bluetooth communication is available or not to a previous terminal which has been connected immediately before the step of disconnecting the Bluetooth connection, and

when the Bluetooth connection between the previous terminal and the vehicle is not established, determining whether the Bluetooth communication is available from a highest priority terminal of terminals registered in a terminal registration mode for the Bluetooth connection of the vehicle in order of priority.

7. A method for controlling a Bluetooth connection, comprising steps of:

connecting a terminal with a vehicle through a Bluetooth connection;

deleting the terminal from a terminal list registered in the vehicle for the Bluetooth connection;

disconnecting the Bluetooth connection according to the deletion;

automatically determining whether a Bluetooth communication of the terminal is available or not in the vehicle, when the disconnection of the Bluetooth connection is detected;

requesting the Bluetooth connection again from the vehicle to the terminal, when receiving from the terminal a response indicating the Bluetooth communication is available; and

connecting the vehicle and the terminal by requesting the Bluetooth connection again.

8. A method for controlling a Bluetooth connection according to claim 7, wherein the step of automatically determining whether a Bluetooth communication of the terminal is available or not includes:

when the terminal is deleted in a terminal list registered in the vehicle, determining whether the Bluetooth communication is available from a highest priority terminal of terminals registered in a terminal registration mode for the Bluetooth connection of the vehicle in order of priority,

when the terminal is not deleted in the terminal list registered in the vehicle, determining whether the Bluetooth communication is available or not to a previous terminal which has been connected immediately before the step of disconnecting the Bluetooth connection, and

when the Bluetooth connection of the previous terminal and the vehicle is not established, determining whether the Bluetooth communication is available from the highest priority terminal of terminals registered in the terminal registration mode for the Bluetooth connection of the vehicle in order of priority.

9. A method for controlling a Bluetooth connection comprising steps of:

requesting a Bluetooth connection to a terminal list registered in a vehicle for the Bluetooth connection, in a state in which the Bluetooth connection of the vehicle and the terminal is disconnected;

attempting the Bluetooth connection by repeating the request twice or more, when the Bluetooth connection is not established;

resetting a Bluetooth module provided in the vehicle, when the Bluetooth connection is not established even after the repeating of the request;

attempting the Bluetooth connection by repeating the request twice or more the Bluetooth connection to a terminal list registered in a vehicle, registering at least one of the list in the vehicle after the resetting of the Bluetooth module; and

providing a user of the vehicle with a message requesting to confirm a Bluetooth activation state of the terminal on a display device provided in the vehicle, when the Bluetooth connection is not established even after the repeating of the request.

10. A method for controlling a Bluetooth connection according to claim 9, wherein the step of requesting the Bluetooth connection to the terminal list registered in the vehicle includes requesting the Bluetooth connection from a highest priority terminal of registered terminals in order of priority, by requesting the Bluetooth connection to each of the terminals one by one according to the priority and by eliminating duplicate attempts of the Bluetooth connection request.
