BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 schematically illustrates an inventive communication system comprising the first communication module and the second communication module.



DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
In FIG. 1, a communication system 10 according to the present invention is schematically shown. The communication system 10 comprises a first communication module 11 and a second communication module 12. The first and second communication modules 11, 12 communicate with one another by means of a wireless communication interface 15 or a wireless communication link 15. The wireless communication interface 15 of the communication system 10 may comprise HomeLinkTM technology, which is a product of Johnson controls, Inc. However, it should be appreciated that other wireless systems could alternatively be used. The communication between the first module 11 and the second module 12 is either performed in an unidirectional manner or in a bidirectional manner. A bidirectional communication between the first and second communication modules 11, 12 is preferred.
The first communication module 11 is preferably located inside a vehicle 1. The second communication module 12 is preferably located in or assigned to a Garage Door Opener 3 (hereinafter also designated by GDO). Alternatively or additionally, the second communication module 12 could be located in or assigned to a home 2. The home 2 could be any house, apartment, office or the like. The GDO and/or the home 2 could be connected to the second communication module 12 wirelessly and/or by a landline (wire-bound).
Due to the 1-way, or preferably 2-way, communication, it is possible to exchange information and/or commands between the vehicle 1, the GDO 3 and/or the home 3 by means of the inventive communication system and vice versa. The communication between the vehicle 1 and the GDO/home 2, 3 is preferably a wireless communication over the communication link 15. The communication between the GDO 3 and the home 2 can be provided wirelessly and/or by a landline (wire bound).
The GDO 3 according to the present invention is any means to open a garage door and/or a gate. For example, one possible GDO 3 is the commercially available Chamberlain GOD system. The 1-way, or preferably 2-way, communication can be deployed within the HomeLinkTM system using the 1-way, or preferably 2-way, communication of the Chamberlain GDO systems. However, it should be appreciated that any other garage door opener or any other barrier system could be employed.
The vehicle 1 could be any vehicle known to a person skilled in the art. The vehicle 1 comprises means (e.g. the first communication module 12) that allow the 1-way, or preferably 2-way, communication with the GOD 3 and/or the home 2 system. The vehicle 1 preferably includes a global positioning system (GPS) or another location sensing means.
In one embodiment, a first information, or a vehicle status information, is communicated from the first communication module 11 of the vehicle 1 to the second communication module 12 of the GDO 3 and/or home 2 systems. The vehicle 1 knows its location through the GPS or other location sensing means and preferably communicates the first information to the GDO 3 and/or home 2 system as the vehicle 1 approaches the home 2 or gate barrier. Alternatively, the vehicle 1 could communicate the first information to the GDO 3 and/or home 2 upon activation of the GDO 3 from the vehicle 1. The first information could include tire pressure; exterior, interior or engine temperature; battery health or battery charge level; electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV) charging status; door lock status; window position status; headlight status; vehicle heading, e.g. the vehicle being pulled into the garage forwardly or the vehicle being backed into the garage; oil level, oil quality or the time/mileage until the next oil change; odometer reading; GPS/location data; and diagnostics information. The preferred first information sent from the vehicle 1 to the GDO 3 and/or home 2 are listed as follows:

    
    
        Tire Pressure
        Vehicle Temp—Exterior, Interior, Engine
        Fuel
        Battery—Health, State of Charge
        EV/PHEV charging status
        Doors Locked
        Windows Up
        Headlights on
        Vehicle ‘Heading’ (pulled in/backed in)
        Oil—Level, Quality, Time/Mileage to Change
        Odometer
        Washer Fluid
        GPS/Location Data
        Diagnostics
    
    


In another exemplary embodiment, the GDO 3 has a second information such as status information that can be communicated to the vehicle 1. Specifically, the GDO 3 has a second information, such as status information, that is useful to be communicated to the home 2 network systems. The second information could include garage door status (e.g. open, opening, closed, closing, diagnostics, etc.), light status (e.g. on, off or operating), safety photocell beam status (e.g. interrupted or fault), power line interruption status (e.g. length of interruption, brown out), garage intruder sensor status, information from a vehicle-in position sensor, information from a sound monitoring sensor, information from a magnetic sensor, information from an atomic clock, information from an ambient light sensor, information from a temperature sensor, information from a motion detection sensor or information from a camera. The second information of the GDO 3 preferably includes information from one or any combination of two and more sensors listed below:

    
    
        Door Status Open, Opening, Closed, Closing, Diagnostics, etc.
        Light Status On/Off, Operating
        Safety Photocell Beam Interrupted/Fault
        Power Line (120V) Interruption, Length of Interruption, Brown Out
        Garage Intruder sensor status
        Vehicle in position sensor
        Sound monitoring sensor
        Magnetic sensor
        Atomic Clock
        Ambient Light sensor
        Temperature sensor
        Motion Detection
        Camera
    
    


In still another exemplary embodiment, the home 2 has a second information such as home status information that can be communicated to the vehicle 1 and/or to the GDO 3. Preferably, the home status information is communicated to the vehicle 1 and to the GDO 3. The home network status could include security information; heating, ventilating and air conditioning (HVAC) information; settings information; power failure information; sprinkler system status or settings information; and rain sensor information. The second information of the home 2 preferably includes information from one or more of the following:

    
    
        Security
        Heating, Ventilating and Air Conditioning
        Settings
        Power Fail
        Sprinkler Status/Settings
        Rain Sensor
    
    


Preferably, the GDO 3 communicates with the home lighting system to turn garage light on. More preferably, when the GDO 3 is activated by the vehicle 1 or by the home 2 network. These lights could be ‘timed’ to turn on/off with the GDO 3 lights or some other time interval.
Preferably, the vehicle 1 comprises a remote start function/system. If the vehicle 1 senses that it is within a garage (and/or if the GDO 3 transmits the information that the GDO 3 is currently opened, closed, opening, closing, etc.), then the vehicle 1 sends the appropriate communication to the GDO 3 prior to starting the vehicle 1 from a remote command to assure that the garage door is open prior to starting the vehicle 1. Also, the vehicle system preferably assures that the vehicle 1 is secure for anti-thief. The remote start system follows the following steps: assure that the vehicle 1 is in the garage, open the garage door (if necessary), assure that the garage door is opened, start the vehicle 1 and optionally secure the vehicle 1 (e.g., lock the doors, roll up the windows and arm the alarm system). Specifically, these steps are listed as follows:

    
    
        Vehicle in Garage
        Garage door open/closed
        Assure door open
        Start vehicle
        Secure Vehicle (Lock, Windows, Armed)
    
    


When the vehicle 1 senses through the location sensing means described above that it is not in the proper position to have the door close without harm to property or life, a communication is sent from the vehicle 1 to the GDO 3 to ‘force’ the GDO 3 into the open position. This ‘automatic reverse request’ system can only force the GDO 3 ‘up’, or open, and it only occurs when the vehicle location and obstruction are known. These elements are listed below:

    
    
        Up-only command
        GPS/Location vehicle known
        Obstruction known
    
    


Additionally, the vehicle 1 preferably receives a communication from the GDO 3 that the garage door is opening or closing. The vehicle 1 is then able to compare its location to the garage door and warn the driver not to enter the garage if the garage door is closed or closing.
Preferably, the GDO 3 provides cycle information including when, how often and/or by whom the garage door has been opened in the past. The GDO 3 preferably stores and/or communicates cycle information to the vehicle 1 and/or the home 2 network. The GDO 3 cycle counter preferably includes information such as the date, the time since departure, a time/date stamp (e.g. with an atomic clock) and the amount of daylight. These elements are listed as follows:

    
    
        To date
        Since departure
        Time/Date stamp (atomic clock)
        Daylight/darkness
    
    


Preferably, the clock inside the GDO 3, the clock inside the home 2 and the clock inside the vehicle 1 all synchronize with one another.
Proper positioning of the vehicle 1 within the garage is desirable. Through the use of sensors and the 2-way communication between the GDO 3 and vehicle 1, a process is preferably developed to notify the driver that the vehicle 1 is positioned well within the garage. The GDO 3, therefore, preferably comprises and/or is connected to a sensor that senses the position and/or velocity of the vehicle 1 when the vehicle 1 is in or close to the garage. The sensors could also include a GPS or compass sensor; a beam broken sensor; and a vehicle speed sensor. The preferred sensors are listed as follows:

    
    
        GPS/Compass
        Beam Broken
        Vehicle Speed
    
    


Preferably, the garage interior lights are sensed by the GDO 3 and their status is communicated to the vehicle 1 and/or home 2 network. Based on the signal of the sensor appropriate actions are preferably initiated. GDO 3, vehicle 1 or home 2 could turn on the garage ceiling, or interior, lights as a function of an ambient light sensor and/or an atomic clock reading. In other words, the lights could be turned on in response to the garage being dark or in response to it being past a predetermined time. The factors for turning on the lights are listed as follows:

    
    
        GDO ambient light sensor
        Atomic clock reading
    
    


By means of the 1-way, or preferably 2-way, communication between the GDO 3 and the vehicle 1, data (e.g. files) are preferably communicated or exchanged that are preferably not associated with GDO 3 or the vehicle 1 functioning.
In another exemplary embodiment, a command from the vehicle 1 is communicated to turn the GDO 3 lights on, preferably without actuating the GDO 3. In other words, the vehicle 1 can turn on the garage lights without opening or closing the garage door.
In another exemplary embodiment, the GDO 3 comprises a learn functionality. Specifically, a ‘learn’ button for the GDO 3 can be placed within the vehicle 1 to improve the training process of the vehicle 1 to a particular GDO 3. The 2-way communication between the GDO 3 and vehicle 1 would facilitate this utility.
Preferably, the GDO 3 can be placed in a ‘vacation’ mode, which locks the GDO 3 from activation from remote transmitters. This function/command is preferably communicated to the GDO 3 from the vehicle 1.
As a vehicle 1 ‘approaches’ a GDO 3 the GPS/location information could be communicated from the vehicle 1 to the GDO 3. This could be useful to prepare the GDO 3 to activate (wake up) or notify individuals within the garage that a vehicle 1 is approaching. Among other actions, the GDO 3 could turn the lights on or play a sound notification in response to a vehicle 1 approaching.
Preferably, a sensor is placed with the garage. That sensor could be connected to the GDO 3 and/or the home 2 system and could sense garage intrusion (particularly if the garage is closed). If a garage intrusion is detected, the GDO 3 could communicate this status to the vehicle 1 as the vehicle 1 approaches the GDO 3 or upon vehicle 1 activating the GDO 3. This information could be communicated to the vehicle driver by the vehicle 1. The sensors could include a motion detect sensor, a fixed kit camera sensor or even the vehicle's alarm system. The preferred sensors are listed as follows:

    
    
        Motion Detect
        Fixed Kit Camera
        Utilize Vehicle Alarm
    
    


The foregoing invention has been described in accordance with the relevant legal standards, thus the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and fall within the scope of the invention.
