Abstract

A method for extending a reception range of a vehicle remote control system includes: receiving, at a repeater, a first radio frequency (RF) signal having inbound data packets indicating a vehicle function to be performed from a remote transmitter; generating, at the repeater, a second RF signal by placing outbound data packets indicating the vehicle function to be performed between the inbound data packets until reception of the first RF signal is complete; and transmitting, from the repeater, the second RF signal to a reception module of a vehicle remote control system.

Claims

1. A method for extending a reception range of a vehicle remote control system, comprising:

receiving, at a repeater, a first radio frequency (RF) signal having inbound data packets indicating a vehicle function to be performed from a remote transmitter;

generating, at the repeater, a second RF signal by placing outbound data packets indicating the vehicle function to be performed between the inbound data packets until reception of the first RF signal is complete; and

transmitting, from the repeater, the second RF signal to a reception module of a vehicle remote control system.

2. The method of claim 1, further comprising:

performing, in a vehicle, the vehicle function indicated by the inbound or outbound data packets of the second RF signal.

3. The method of claim 1, wherein the vehicle function indicated by the inbound or outbound data packets is associated with remote keyless entry or remote start.

4. The method of claim 1, further comprising;

reading, at the repeater, a strength of the first RF signal;

determining, at the repeater, if the strength of the first RF signal is above or below a threshold; and

not generating, at the repeater, the second RF signal if the first RF signal is above the threshold;

or

generating, at the repeater, the second RF signal if the first RF signal is below the threshold.

5. The method of claim 1, further comprising;

down-converting, at the repeater, the first RF signal to a base-band signal; and

filtering, at the repeater, the base-band signal prior to generating the second RF signal.

6. A method for learning a two-way transmitter/receiver initially incompatible with a vehicle remote control system, comprising:

receiving, at a repeater, a first signal including a command indicating a vehicle function to be performed from the two-way transmitter/receiver;

converting, at the repeater, the command to a second signal that is compatible with a wireless transmission scheme of the vehicle remote control system;

transmitting, from the repeater, the second signal to the vehicle remote control system.

7. The method of claim 6, further comprising:

transmitting, from the repeater, a third signal indicating that the first signal was received by the repeater or the vehicle remote control system to the two-way transmitter/receiver.

8. The method of claim 6, further comprising:

performing, by using the vehicle remote control system, the vehicle function indicated by the command of the first signal.

9. The method of claim 7, wherein the first signal and third signal are radio frequency (RF), ZigBee, Near Field Communication (NFC), Bluetooth, ultra-wide hand or infrared signals and the second signal is an RF signal.

10. A system for extending a reception range of a vehicle remote control system, comprising:

a repeater for receiving a first radio frequency (RF) signal having inbound data packets indicating a vehicle function to be performed from a remote transmitter;

generating a second RF signal by placing outbound data packets indicating the vehicle function to be performed between the inbound data packets until reception of the first RF signal is complete; and

transmitting the second RF signal; and

a remote control module including a reception module for receiving the second RF signal, the remote control module for instructing the vehicle to perform the vehicle function indicated by the inbound or outbound data packets of the second RF signal.

11. The system of claim 10, wherein the vehicle function indicated by the inbound or outbound data packets is associated with remote keyless entry or remote start.

12. The system of claim 10, wherein the repeater reads a strength of the first RF signal;

determines if the strength of the first RF signal is above or below a threshold; and

does not generate the second RF signal if the first RF signal is above the threshold;

or generates the second RF signal if the first RF signal is below the threshold.

13. The system of claim 10, wherein the repeater down-converts the first RF signal to a base-band signal;

and filters the base-band signal prior to generating the second RF signal.

14. The system of claim 10, wherein the remote control module is a factory-installed remote control module.

15. The system of claim 10, wherein the factory-installed remote control module has a first reception range and the repeater has a second reception range that is greater than the first reception range.

16. The system of claim 10, wherein when the remote transmitter is a two-way transmitter/receiver initially incompatible with the remote control module, the repeater receives a third signal including a command indicating a vehicle function to be performed from the two-way transmitter/receiver;

converts the command to a fourth signal that is compatible with a wireless transmission scheme of the remote control module; and

transmits the fourth signal to the remote control module.

17. The system of claim 16, wherein the repeater transmits a fifth signal indicating that the third signal was received by the repeater or the remote control module to the two-way transmitter/receiver.

18. The system of claim 16, wherein the vehicle function indicated by the command of the third signal is performed by using the remote control module.

19. The system of claim 17, wherein the third signal and fifth signal are radio frequency (RF), ZigBee, Near Field Communication (NFC), Bluetooth, ultra-wide band or infrared signals and the fourth signal is an RF signal.

20. The system of claim 16, wherein the remote control module is a factory-installed remote control module.

21. A method for extending a reception range of a vehicle remote control system, comprising:

receiving, at a repeater, a first radio frequency (RF) signal having inbound data packets indicating a vehicle function to be performed from a remote transmitter;

down-converting, at the repeater, the first RF signal to a base-band signal;

filtering, at the repeater, the base-band signal;

after filtering the base-band signal, generating, at the repeater, a second RF signal by placing outbound data packets indicating the vehicle function to be performed between the inbound data packets until reception of the first RF signal is complete; and

transmitting, from the repeater, the second RF signal to a reception module of a vehicle remote control system.
