Abstract: A head unit of a vehicle may include an antenna, a combo module supporting first communication and second communication using the same frequency through the antenna, and a controller for controlling the combo module to be switched to one of a first communication mode and a second communication mode. If the head unit is connected to an external device including a combo module supporting the first communication and the second communication simultaneously in the first communication mode and the second communication mode, the controller may synchronize a cycle of a first communication window and a second communication window with the external device. As such, device stability and efficiency may be improved.

Abstract: An audio-video-navigation (AVN) system for vehicles includes: a communication unit connected with a service or device; a memory storing at least one of first operation parameters or at least one of second operation parameters corresponding to a connected service or device; and a controller determining whether a normal operation is performed with the at least one loaded operation parameter and changing the at least one loaded parameter based on whether a normal operation is performed with the at least one loaded operation parameter. The controller performs a control operation to store at least one part of adaptively changeable predetermined parameters as the at least one of second operation parameters based on whether a normal operation is performed with the at least one loaded operation parameter.

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: Disclosed are a wireless connection system capable of conveniently connecting two devices through short-range wireless communication and a method of controlling the same. A method of controlling a mobile terminal performing wireless connection to a vehicle includes displaying a first menu corresponding to a first connection type and a second menu corresponding to a second connection type according to a first command, selecting the first menu or the second menu according to a second command, and performing automatic connection to the vehicle through a connection type corresponding to a menu selected by the second command. The first connection type uses information about whether a wireless connection address of the vehicle is equal to a pre-stored address and the second connection type uses the wireless connection address acquired from a digital code provided through the vehicle.

Abstract: Disclosed are a vehicle capable of changing an audio output mode according to audio streamed from a smart device connected thereto and a control method therefor. A method of changing an audio output mode in a vehicle Audio Video Navigation (AVN) system include setting a steaming channel through wireless connection to a smart device and the AVN system, determining whether navigation announcement voice is detected from streaming data received through the streaming channel, and if the navigation announcement voice is detected, changing the audio output mode from a mode in which the navigation announcement voice is not output through a vehicle speaker to a streaming mode in which the navigation announcement voice is output through the vehicle speaker.

Abstract: A method for controlling an electric device in a vehicle includes: establishing communication with a first mobile device previously recognized by the vehicle; collecting first pattern information from the vehicle; comparing the first pattern information with second pattern information stored in the first mobile device; and discovering a second mobile device based on the comparison of the first pattern information with the second pattern information.

Abstract: A vehicle capable of recognizing a driver having a mobile device includes a smart connector configured to acquire wireless connection information of the driver's mobile device from a wearable device connected to the mobile device. A head unit is configured to perform connection with the mobile device using the wireless connection information of the mobile device acquired from the smart connector.

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 performing connection through Bluetooth by a head unit of a vehicle with a mobile device which is paired with the head unit includes transmitting, by a controller, a first message for checking a link-key to the mobile device. The controller transmits, upon receiving a second message indicating that connection is refused from the mobile device, a third message for starting a new pairing procedure to the mobile device.

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: 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: 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.
