Abstract: A method for performing Bluetooth pairing with a mobile device by a head unit of a vehicle includes: initiating a Bluetooth pairing procedure between the mobile device and the head unit; storing an address of the mobile device upon the initiation of the pairing procedure; detecting an error generated in the pairing procedure; and automatically retrying the pairing procedure using the stored address of the mobile device or terminating the pairing procedure, based on a type of the detected error.

Abstract: An in-vehicle Bluetooth pairing providing method and an apparatus using the same are disclosed. The Bluetooth pairing method in an in-vehicle head unit includes: initiating a Bluetooth automatic connection procedure with a pre-registered first user device upon application of power; canceling the initiated automatic connection procedure in accordance with user input; searching for a connectable user device; establishing a logical link with the searched user device; and transmitting a connection request message to the user device through the established logical link.

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.

Abstract: An in-vehicle Bluetooth load control method and an apparatus using the same are disclosed. A Bluetooth load dispersion method for an in-vehicle head unit includes assigning and retaining priority per profile, executing a first profile. When execution of second to n-th profiles is requested, executing the second to n-th profiles, comparing priority level assigned to the first profile with priority level assigned to the second to n-th profiles, and classifying the profiles as a main service and sub services based on a result of the comparison. Wherein is a natural number equal to or greater than 2 and is a total number of profiles in the plurality of profiles. Consequently, Bluetooth load is effectively controlled in a multi Bluetooth profile environment.

Abstract: An in-vehicle Bluetooth pairing method includes commencing an automatic Bluetooth connection procedure with a first user device when power is supplied to an in-vehicle head unit. A progress state of the commenced automatic Bluetooth connection procedure is checked according to a request of new user device registration. A disconnection procedure corresponding to the checked progress state is performed, and a pairing mode for the new user device registration is applied.

Abstract: A method for controlling a Bluetooth connection according an embodiment of the present disclosure includes requesting a confirmation of connectable profiles from a vehicle to a terminal, and responding to the connectable profiles in response to the confirmation request, requesting a first connection of the connectable profiles, determining whether a hands-free profile of the connected profiles is connected based on the connection request, and requesting a second connection of the hands-free profile of the connectable profiles prior to other profiles of the connectable profiles which are not connected, when it is determined that the connection of the hands-free profile is failed.

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.
