Abstract
A method of controlling a hands-free system for a vehicle includes connecting with a cellular phone through local area communication. A call conversation state is entered when a hands-free function activates. A call termination command is received from a driver. A call termination message is transmitted to the connected cellular phone. When a success message is not received from the connected cellular phone in response to the call termination message, the call termination message is retransmitted by a preset number of times until the success message is received.
Claims20
A method of controlling a hands-free system for a vehicle, the method comprising:
- connecting with a cellular phone through local area communication;
- entering a call conversation state when a hands-free function activates;
- receiving a call termination command from a driver;
- transmitting a call termination message to the connected cellular phone;
- and
- retransmitting, when a success message is not received from the connected cellular phone in response to the call termination message, the call termination message by a preset number of times until the success message is received.
A hands-free system for a vehicle, comprising:
- a local area communicator configured to exchange a signal with a cellular phone through local area communication;
- a user input configured to receive a call termination command from a driver during a call conversation state after a hands-free function is activated;
- and
- a controller configured to control the local area communicator to transmit a call termination message to the cellular phone connected with the local area communication upon receiving the call termination command, and to control the local area communicator to retransmit, when a success message is not received from the connected cellular phone in response to the call termination message, the call termination message by a preset number of times until the success message is received.
The hands-free system according to claim 11, wherein the controller compulsively transits the call conversation state to a call termination state when the success message is not received from the connected cellular phone after the call termination message is retransmitted by the preset number of times.
An audio/video/navigation (AVN) system for a vehicle for providing a hands-free function, the AVN system comprising:
- a Bluetooth module paired with a cellular phone and configured to exchange a signal with the cellular phone;
- a controller configured to execute the hands-free function with respect to a call performed through the paired cellular phone;
- and
- a user input configured to receive a call termination command from a driver during a call conversation state when the hands-free function is executed,
- wherein the controller controls the Bluetooth module to transmit a call termination message to the cellular phone upon receiving the call termination command, and to control a local area communicator to retransmit, when a success message is not received from the cellular phone in response to the call termination message, the call termination message by a preset number of times until the success message is received.
