As an example of information accessed from the Internet 72, vehicle appliance 12 may download customizable horn tunes, turn signal noises, etc., from the Internet via garage door opener 56 and computer 66. Using this downloaded information, the vehicle's horn may then honk using a customizable horn tune and the vehicle speakers may emit a customized sound for the driver to hear each time the vehicle turn signals go on and off. Both the vehicle's horn and the vehicle's turn signal speakers are connected to vehicle electrical bus 34.
Vehicle appliance 12 may also communicate to home lighting device 68 via garage door opener 54 while vehicle 52 is located in the vicinity of garage 56. For example, the driver may use vehicle appliance 12 to communicate with home lighting device 68 via garage door gateway 54 to turn on lights in the home while the driver is in the vehicle and is ready to pull the vehicle out of garage 54. Likewise, the driver may also use vehicle appliance 12 to communicate with home security device 70 via garage door gateway 54 to turn on the security system after the driver has just pulled out the vehicle from garage 56.
If vehicle 52 is out of the vicinity of garage door opener 54, the driver may use cell phone 13 to make a cell phone call with computer 66 via the Internet 72 in order to establish communications with garage door opener 54. For instance, the driver may indicate to computer 66 that the lights of the home need to be turned on. In this instance, computer 66 conveys this information to garage door opener 54 which in turn controls home lighting device 68 accordingly. Similarly, the driver may use cell phone 13 to make a cell phone with computer 66 via the Internet 72 in order to advise the computer that home security device 70 needs to be turned on. In this instance, computer 66 conveys this information to garage door opener 54 which in turn controls home security device 70 accordingly.
In addition to making a cell phone call to computer 66 regarding the control of either home lighting and security device 68 and 70, the driver may make the cell phone call to the computer to inquire about the status of either of these devices.
