Abstract

A method for training a trainable transmitter in a vehicle that includes receiving a request to enter a training mode of the trainable transmitter from a user, beginning a training mode of the trainable transmitter, receiving a control signal from an original transmitter associated with a remote control system, detecting a frequency and control data of the control signal. The method further includes determining if the control signal is a fixed code signal or a rolling code signal. If the control signal is a fixed code signal, storing the detected frequency and control data. If the control signal is a rolling code signal, comparing the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shifting the detected frequency to match one of the predetermined frequencies.

Claims

receiving a request to enter a training mode of the trainable transmitter from a user;

beginning a training mode of the trainable transmitter;

receiving a control signal from an original transmitter associated with a remote control system;

detecting a frequency and control data of the control signal;

determining if the control signal is a fixed code signal or a rolling code signal;

if the control signal is a fixed code signal, storing the detected frequency and control data; and

if the control signal is a rolling code signal, comparing the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shifting the detected frequency to match one of the predetermined frequencies.

2. A method according to claim 1, wherein the plurality of predetermined frequencies are associated at least one of remote control systems and manufacturers.

3. A method according to claim 1, wherein each of the plurality of predetermined frequencies are associated with a frequency range

4. A method according to claim 3, wherein the step of comparing includes comparing the detected frequency to a frequency range to determine if the detected frequency is included in the frequency range.

5. A method according to claim 1, further including storing the shifted frequency and control data.

6. A method according to claim 1, wherein the trainable transmitter is integrated into a vehicle interior element.

7. A method according to claim 6, further including associating the stored frequency and control data with an input device coupled to the trainable transmitter.

8. A trainable transmitter, comprising:

a receiver configured to receive signals; and

a control circuit coupled to the receiver and configured to;

receive a control signal from an original transmitter via the receiver,

detect a frequency and control data of the control signal,

determine if the control signal is a fixed code signal or a rolling code signal and if the control signal is a fixed code signal,

store the detected frequency and control data and, if the control signal is a rolling code signal, compare the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shift the detected frequency to match one of the predetermined frequencies.

9. A system according to claim 8, wherein the plurality of predetermined frequencies are associated at least one of remote control systems and manufacturers.

10. A system according to claim 8, wherein each of the plurality of predetermined frequencies are associated with a frequency range

11. A system according to claim 10, wherein the step of comparing includes comparing the detected frequency to a frequency range to determine if the detected frequency is included in the frequency range.

12. A system according to claim 8, further including a memory for storing the shifted frequency and control data.

13. A system according to claim 8, wherein the trainable transmitter is integrated into a vehicle interior element.

14. A system according to claim 13, further including an input device, wherein the control circuit is configured to associate the stored frequency and control data with the input device.

15. A trainable transmitter, comprising:

a control circuit coupled to the receiver and configured to;

receive a control signal from an original transmitter via the receiver,

detect a frequency and control data of the control signal,

determine if the control signal is a fixed code signal or a rolling code signal and if the control signal is a fixed code signal,

store the detected frequency and control data and, if the control signal is a rolling code signal, compare the detected control signal frequency to a plurality of predetermined frequencies and based on the comparison, shift the detected frequency to match one of the predetermined frequencies, and

generate a control signal in response to an actuation of an input device, the control signal including the control data and the detected frequency or the shifted frequency.

16. A system according to claim 15, wherein the plurality of predetermined frequencies are associated at least one of remote control systems and manufacturers.

17. A system according to claim 15, wherein each of the plurality of predetermined frequencies are associated with a frequency range

18. A system according to claim 17, wherein the step of comparing includes comparing the detected frequency to a frequency range to determine if the detected frequency is included in the frequency range.

19. A system according to claim 15, further including a memory for storing the shifted frequency and control data.

20. A system according to claim 15, further including an input device, wherein the control circuit is configured to associate the stored frequency and control data with the input device.
