Universal vehicle based garage door opener control system and method

A vehicle-based control system for use with a barrier operating system comprising a motor for opening and closing a barrier, a receiver in communication with the motor, and a remote transmitter for transmitting an activation signal, the activation signal comprising a radio frequency carrier signal modulated with a fixed codeword, the activation signal for receipt by the receiver for use in activating the motor to open and close the barrier, the control system comprising:

• (a) a transceiver to be mounted in a vehicle and configured to
• (1) receive an activation signal from the barrier operating system transmitter, and
• (2) transmit an activation signal for receipt by the barrier operating system receiver;
• and
• (b) a controller to be mounted in a vehicle in communication with the transceiver and a user input device, wherein the controller comprises a digital radio frequency memory (DRFM) and is configured to
• (1) store the fixed codeword of the received activation signal,
• (2) sample the carrier signal of the received activation signal using the DRFM and transfer the sampled carrier signal from the DRFM to the transceiver, and
• (3) control the transceiver to transmit an activation signal comprising the sampled carrier signal modulated with the stored fixed codeword in response to user input.

A vehicle-based control method for use with a barrier operating system comprising a motor for opening and closing a barrier, a receiver in communication with the motor, and a remote transmitter for transmitting an activation signal, the activation signal comprising a radio frequency carrier signal modulated with a codeword, the activation signal for receipt by the receiver for use in activating the motor to open and close the barrier, the control method comprising:

• (a) identifying an activation scheme having at least a variable codeword format associated therewith;
• (b) generating a variable codeword based on the identified activation scheme;
• (c) storing sampled versions of a plurality of radio frequency carrier signals in a digital radio frequency memory (DRFM);
• and
• (d) selecting a radio frequency carrier signal corresponding to one of the samnied versions of the radio frequency carrier signals based on the identified activation scheme, the sampled version of the selected radio frequency carrier signal and the generated variable codeword for use in transmitting an activation signal.
