Patent ID: 8565777

Claim:
A vehicle comprising a hands-free system, the hands-free system comprising: a processing circuit calculating positional coordinates of the hands-free system; a short-range communication unit electrically coupled with a mobile telephone and receive positional coordinates of the mobile telephone; and a microcontroller unit receiving the positional coordinates of the hands-free system and the mobile telephone, analyzing positional coordinates of the mobile telephone in relation to positional coordinates of the hands-free system, determining whether the mobile telephone is located at a defined position of the vehicle, and establishing a data connection with the mobile telephone that is located at the defined position; wherein when the defined position is a range of where a driver's seat is placed in the vehicle; a linear distance between the driver's seat and the hands-free system and a range of allowable error are stored in the microcontroller unit; the microcontroller unit comparing an ordinate of the mobile telephone with an ordinate of the hands-free system, comparing an abscissa of the mobile telephone with an abscissa of the hands-free system, comparing linear distances between the mobile telephone and the hands-free system with the stored linear distance, and determining whether the mobile telephone is located at the defined position based on the comparison of the ordinate of the mobile telephone with the ordinate of the hands-free system, the comparison of the abscissa of the mobile telephone with the abscissa of the hands-free system, and the comparison of the linear distances between the mobile telephone and the hands-free system with the stored linear distance.
