Abstract

A system for opening and closing a garage door is provided. The system includes a vehicle communication module mounted to a vehicle, and a garage communication module, the vehicle communication module and the garage communication module preferably performing Bluetooth™ communication. On the basis of the communication of a vehicle identifier and engine state information, a garage door can be automatically opened and closed.

Claims

1. A system for automatically opening and closing a garage door, comprising:

a vehicle controller for controlling an operation of a vehicle and detecting vehicle information comprising an engine operation state;

a vehicle communication module mounted on the vehicle, said vehicle module being provided with an input port through which said vehicle information is input and containing an indicator that the vehicle is a registered vehicle;

a garage communication module having an output port, said garage module performing wireless communication with the vehicle module;

a garage controller generating a garage door opening/closing control signal using data input from said output port of said garage module according to whether the vehicle is registered or not wherein said garage controller generates the garage door opening/closing control signal according to an operating state of the vehicle that enters or exits a garage if the vehicle is registered; and

a garage door opening/closing device actuated by the garage door opening/closing control signal input from said garage controller, wherein said garage controller analyzes engine information input from said garage communication module and provides the garage door opening control signal to the garage door opening/closing device if an engine of the vehicle operates.

2. The system of claim 1, wherein both said vehicle communication module and said garage communication module are Bluetooth™

communication modules.

3. A method for automatically opening and closing a garage, comprising:

querying for a unique identifier of a vehicle that approaches a garage;

detecting said querying for the unique identifier of the vehicle;

transmitting the unique identifier of the vehicle if said querying is detected;

comparing the transmitted unique identifier of the vehicle to a predetermined registered identifier;

querying for vehicle information, including engine operating state, if the transmitted unique identifier is identical to the predetermined registered identifier;

detecting said querying for the vehicle information;

transmitting vehicle information if said querying is detected; and

analyzing said transmitted vehicle information and generating a garage door opening/closing control signal according to the engine operating state.

4. The method of claim 3, further comprising generating a garage door closing control signal if the unique identifier of the vehicle is not identical to the predetermined registered identifier in said comparing.

5. The method of claim 3, further comprising generating a garage door opening control signal if the engine of the vehicle starts to operate.

6. The method of claim 3, further comprising generating a garage door closing control signal if the engine of the vehicle stops.

7. The method of claim 3, wherein said querying and transmitting occur via wireless communication.

8. The method of claim 7, wherein said wireless communication employs a Bluetooth™

protocol.
