Abstract

A system for enabling the hands-free use of a mobile telephone in a vehicle includes a processing circuit, a short-range communication unit and a microcontroller unit. The processing circuit calculates positional coordinates of the system. The short-range communication unit connects with the mobile telephones and receives positional coordinates of all nearby mobile telephones. The microcontroller unit receives the positional coordinates of the system and the mobile telephones, determines which mobile telephone is located in a defined position of the vehicle, and creates a wireless connection with the mobile telephone.

Claims

1. 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.

2. The vehicle of claim 1, wherein the processing circuit comprises a global positioning system receive.

3. The vehicle of claim 1, wherein the defined position is a range of where a driver'"'"'s seat is placed in the vehicle.

4. The vehicle of claim 1, wherein when the microcontroller unit determines that the mobile telephone is not located at the defined position, the microcontroller unit does not establish the connection for data transfers with the mobile telephone.

5. The vehicle of claim 1, wherein the hands-free system establishes the data connection with the mobile telephone via the short-range communication unit.

6. A vehicle comprising a hands-free system, the hands-free system comprising:

a processing circuit calculates positional coordinating 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 establish 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 range of values is stored in the microcontroller unit;

the microcontroller unit calculating absolute difference values between the ordinate of the mobile telephone and the ordinate of the hands-free system, 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 the absolute difference values between the ordinates of the mobile telephone and the hands-free system with the stored range of values, 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 absolute difference values between the ordinates of the mobile telephone and the hands-free system with the stored range of values.

7. The vehicle of claim 6, wherein the processing circuit comprises a global positioning system receive.

8. The vehicle of claim 6, wherein the defined position is a range of where a driver'"'"'s seat is placed in the vehicle.

9. The vehicle of claim 6, wherein when the microcontroller unit determines that the mobile telephone is not located at the defined position, the microcontroller unit does not establish the connection for data transfers with the mobile telephone.

10. The vehicle of claim 6, wherein the hands-free system establishes the data connection with the mobile telephone via the short-range communication unit.
