Abstract

A method for controlling a Bluetooth connection includes turning off an ignition of a vehicle. It is determined whether a terminal connected to a Bluetooth system provided in the vehicle exists or not. When it is determined that the connected terminal exists as a result of determining, a disconnection command for the Bluetooth connection is transmitted from the vehicle to the terminal. The Bluetooth system waits for a time predetermined by the Bluetooth system, after transmitting the disconnection command. After waiting for the predetermined time, it is determined whether a disconnection confirmation message responding to the disconnection command is received from the terminal or not. When it is determined that the disconnection message is received as a result of determining whether the disconnection message is received or not, the Bluetooth system is caused to enter into a sleep mode.

Claims

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

determining whether a reboot is a normal reboot or not, when a Bluetooth system provided in a vehicle is rebooted;

when it is determined that the reboot is a normal reboot as a result of determining, automatically attempting the Bluetooth connection between the Bluetooth system and a terminal;

when it is determined that the reboot is not a normal reboot as a result of determining, waiting for a time predetermined by the Bluetooth system; and

after the predetermined time is elapsed, automatically attempting the Bluetooth connection between the Bluetooth system and the terminal,

wherein the predetermined time is a time to stably complete a disconnection operation of the Bluetooth connection between the Bluetooth system and the terminal.

2. A method for controlling a Bluetooth connection according to claim 1, wherein the step of rebooting the Bluetooth system includes rebooting the Bluetooth system when the level of a battery falls due to aging of the battery of the vehicle or a head unit of the vehicle is reset due to an error of the head unit.

3. A method for controlling a Bluetooth connection according to claim 1, wherein the step of waiting for the predetermined time includes waiting for the predetermined time in a standby mode.
