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,

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, by eliminating duplicate attempts of the Bluetooth requests;

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.
