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 hands-free system, comprising:

a processing circuit configured to calculate positional coordinates of the hands-free system;

a short-range communication unit configured to electronically couple with a mobile telephone and receive positional coordinates of the mobile telephone; and

a microcontroller unit configured to receive the positional coordinates of the hands-free system and the mobile telephone, determine whether the mobile telephone is located at a defined position of a vehicle, and establish a data connection with the mobile telephone that is located at the defined position.

2. The hands-free system of claim 1, wherein the processing circuit comprises a global positioning system receiver.

3. The hands-free system of claim 1, wherein the defined position is a range of a driver'"'"'s seat in the vehicle.

4. The hands-free system 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 data connection with the mobile telephone.

5. The hands-free system 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 configured to calculate positional coordinates of the hands-free system;

a short-range communication unit configured to electrically couple with a mobile telephone and receive positional coordinates of the mobile telephone; and

a microcontroller unit configured to receive the positional coordinates of the hands-free system and the mobile telephone, determine 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.

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

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.

11. The vehicle of claim 6, wherein the microcontroller unit analyzes positional coordinates of the mobile telephone in relation to positional coordinates of the hands-free system, and determines whether the mobile telephone is located at the defined position.

12. The vehicle of claim 11, wherein when the defined position is a range of where a driver'"'"'s seat is placed in the vehicle, a liner 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 compares an ordinate of the mobile telephone with an ordinate of the hands-free system, compares an abscissa of the mobile telephone with an abscissa of the hands-free system, further compares liner distances between the mobile telephone and the hands-free system with the stored liner distance, and determines whether the mobile telephone is located at the defined position based on comparison results.

13. The vehicle of claim 11, 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 calculates absolute difference values between the ordinate of the mobile telephone and the ordinate of the hands-free system.

15. A mobile telephone, comprising:

a control unit;

a processing circuit configured to calculate positional coordinates of the mobile telephone; and

a short-range communication unit configured to search for a hands-free system of a vehicle, establish a data connection with the hands-free system when the hands-free system is found, and output the positional coordinates to the hands-free system under the control of the control unit;

wherein the processing unit controls a hands-free function of the mobile telephone to turn on when the mobile telephone is located at a defined position of the vehicle, based on the positional coordinates of the mobile telephone in relation to positional coordinates of the hands-free system.

14. The vehicle of claim 15, wherein the microcontroller unit compares an ordinate of the mobile telephone with an ordinate of the hands-free system, compares an abscissa of the mobile telephone with an abscissa of the hands-free system, further compares the absolute difference values between the ordinates of the mobile telephone and the hands-free system with the stored range of values, and determines whether the mobile telephone is located at the defined position based on comparison results.

16. The mobile telephone of claim 15, wherein the processing circuit comprises a global positioning system receiver.
