SYSTEM AND METHOD FOR INTEGRATED GARAGE DOOR OPENER AND VEHICLE ENTRY USING MULTI-FREQUENCY TRANSMITTER
First Claim
1. A portable device for controlling a vehicle remote keyless entry (RKE) system and a garage door opener (GDO), the device comprising:
- a controller for generating a function code in response to an operator demand signal and for selecting between a first and second transmission frequency, wherein the operator demand signal is at least one of a RKE demand signal and a GDO demand signal, and the first frequency is selected when the function code is generated in response to a RKE demand signal and the second frequency is selected when the function code is generated in response to a GDO demand signal; and
a multi-frequency transmitter electrically coupled to the controller and an antenna for transmitting the generated function code to at least one of a vehicle remote keyless entry system and a garage door opener at the selected frequency.

Abstract
A portable device for controlling a vehicle remote keyless entry (RKE) system and a garage door opener (GDO), the device including a controller and a multi-frequency transmitter. The controller generates a function code in response to an operator demand signal and selects between a first and second transmission frequency. The operator demand signal is at least one of a RKE demand signal and a GDO demand signal. The first frequency is selected when the function code is generated in response to a RKE demand signal and the second frequency is selected when the function code is generated in response to a GDO demand signal. The multi-frequency transmitter is electrically coupled to the controller and an antenna. The multi-frequency transmitter transmits the generated function code to at least one of a vehicle remote keyless entry system and a garage door opener at the selected frequency.

18. A method for controlling a vehicle remote keyless entry (RKE) system having a first operating frequency and a garage door opener (GDO) having a second operating frequency using a portable device having a controller electrically coupled to a multi-frequency transmitter, the method comprising:
-
determining when at least one of a RKE operator demand signal and a GDO operator demand signal is presented to the controller;
generating a RKE function code and a RKE security code using a predetermined RKE coding scheme when a RKE operator demand signal is presented to the controller;
generating a GDO function code and a GDO security code using a predetermined GDO coding scheme when a GDO operator demand signal is presented to the controller;
transmitting the RKE function code and the RKE security code at the first frequency using the multi-frequency transmitter when a RKE operator demand signal is presented to the controller; and
transmitting the GDO function code and the GDO security code at the second frequency using the multi-frequency transmitter when a GDO operator demand signal is presented to the controller. - View Dependent Claims (19, 20)
