Smart antenna module
View Patent ↗A communication system is provided and may include a receiver that receives an analog signal, a processor in communication with the receiver that converts the analog signal to a digital signal, a control unit that receives the digital signal and communicates an executable command to a vehicle system, and a communication medium in communication with the processor and the control unit and facilitates communication of the digital signal therebetween. The receiver and the processor may be integrated into an antenna module.
1. A system comprising:
a receiver adapted to receive an analog signal;
a processor in communication with said receiver and operable to convert said analog signal to a digital signal;
a control unit adapted to receive said digital signal and communicate an executable command to a vehicle system; and
a communication medium communicating said digital signal between said processor and said control unit,
wherein said receiver and said processor are integrated into an antenna module.
2. The system of claim 1 , wherein said communication medium is a local interconnect network.
3. The system of claim 1 , wherein said analog signal is a radio frequency signal.
4. The system of claim 1 , wherein said antenna module includes a plurality of receivers adapted to receive said analog signal.
5. The system of claim 4 , further comprising a switching circuit adapted to select an optimal signal among said plurality of receivers based on a signal to noise ratio of said analog signal received by each of said plurality of receivers and which has a greatest signal to noise ratio and allow the optimal signal to be communicated to said processor.
6. The system of claim 1 , further comprising a plurality of antenna modules in communication with said control unit and each having a receiver adapted to receive said analog signal.
7. The system of claim 6 , further comprising a switching circuit adapted to select an optimal signal among the receivers of said plurality of antenna modules based on which said analog signal received by each of the receivers has a greatest signal to noise ratio and allow the optimal signal to be communicated to said processor.
8. The system of claim 1 , wherein said antenna module is disposed remotely from said control unit.
9. A method comprising:
receiving a wireless analog signal in an antenna module;
converting said analog signal to a digital signal in said antenna module;
receiving said digital signal in a control unit; and
generating a command signal based on said digital signal.
10. The method of claim 9 , wherein said digital signal is communicated from said antenna module to said control unit via a communication medium.
11. The method of claim 9 , wherein said antenna module includes a receiver and a processor.
12. The method of claim 9 , wherein said wireless analog signal is a radio frequency signal.
13. The method of claim 9 , wherein said antenna module is spaced apart from said control unit.
14. The method of claim 9 , further comprising receiving a second wireless analog signal in a second antenna module.
15. The method of claim 14 , further comprising selecting an optimal signal among the first and second analog signals based on which has a greatest signal to noise ratio and allowing communication of the optimal signal to the control unit.
16. The method of claim 9 , further comprising communicating said command signal to a vehicle subsystem.
17. A radio frequency reception system for a vehicle comprising:
an antenna module having a receiver adapted to receive a radio frequency signal and a processor adapted to convert said radio frequency signal to a digital signal;
an electronic control unit disposed in an instrument panel of the vehicle; and
a communication medium associated with said antenna module and said electronic control unit and providing electrical communication therebetween,
wherein said electronic control unit receives said digital signal via said communication medium and generates a command signal based on said digital signal to actuate a vehicle subsystem.
18. The radio frequency reception system of claim 17 , wherein said communication medium is a local interconnect network.
19. The radio frequency reception system of claim 18 , wherein said antenna module is spaced apart from said instrument panel.
20. The radio frequency reception system of claim 18 , further comprising a second receiver adapted to receive said radio frequency signal.
