Abstract

Example door control systems and methods are described. In one implementation, a method receives image data from a camera mounted to a vehicle. The image data is analyzed by a door control system to determine whether a user is near the vehicle. If a user is identified near the vehicle, the method determines whether the user intends to open a garage door based on the image data.

First claim

The invention claimed is:

1. A method comprising:
receiving image data from a camera mounted to a vehicle;
analyzing, by a door control system, the image data to determine whether a user is proximate the vehicle; and
responsive to determining that a user is proximate the vehicle, determining whether the user intends to open a garage door based on the image data, wherein determining whether the user intends to open a garage door includes:
analyzing the user's current appearance based on the image data; and
determine whether the user intends to open the garage door based on the user's current appearance,

wherein analyzing the user's current appearance includes at least one of analyzing attire worn by the user and determining whether the attire worn by the user indicates that the user intends to leave the garage.

2. The method of claim 1 , wherein the door control system is contained within the vehicle.

3. The method of claim 1 , further comprising opening the garage door responsive to determining that the user intends to open the garage door.

4. The method of claim 1 , wherein analyzing the user's current appearance includes at least one of analyzing attire worn by the user, determining whether the user is carrying a briefcase, determining whether the user is carrying a backpack, and determining whether the user is carrying a suitcase.

5. The method of claim 1 , wherein analyzing the user's current appearance includes at least one of analyzing attire worn by the user and determining whether the attire worn by the user indicates that the user intends to drive the vehicle out of the garage.

6. The method of claim 1 , further comprising:
determining that the user unlocked at least one vehicle door; and
responsive to determining that the user unlocked at least one vehicle door, opening the garage door.

7. The method of claim 1 , further comprising:
receiving historical data indicating the user's previous appearance when opening the garage door; and
wherein determining whether the user intends to open a garage door includes comparing the user's current appearance with the user's previous appearance when opening the garage door.

8. The method of claim 1 , further comprising:
determining the current day and time;
receiving historical data indicating previous days and times that the user opened the garage door; and
wherein determining whether the user intends to open a garage door includes comparing the previous days and times that the user opened the garage door with the current day and time.

9. The method of claim 1 , further comprising:
receiving audio data from a microphone mounted to the vehicle;
analyzing, by the door control system, the audio data to determine words spoken by the user; and
wherein determining whether a user intends to open a garage door is further based on the words spoken by the user.

10. The method of claim 9 , further comprising:
receiving historical data indicating the words previously spoken by the user when opening the garage door; and
wherein determining whether the user intends to open a garage door further includes comparing the current words spoken by the user with words previously spoken by the user when opening the garage door.

11. A method comprising:
detecting a user proximate a vehicle;
receiving images of the user from a camera mounted to the vehicle;
analyzing, by a door control system, the images of the user to determine the user's current appearance;
receiving, by the door control system, historical data indicating the user's previous appearances when opening a garage door; and
determining, by the door control system, whether the user intends to open the garage door by comparing the user's current appearance with the user's previous appearances when opening the garage door,
wherein analyzing the images of the user to determine the user's current appearance includes at least one of analyzing attire worn by the user, determining whether the user is carrying a briefcase, determining whether the user is carrying a backpack, and determining whether the user is carrying a suitcase.

12. The method of claim 11 , wherein detecting a user proximate a vehicle includes analyzing data from at least one sensor mounted to the vehicle.

13. The method of claim 11 , wherein the door control system is contained within the vehicle.

14. The method of claim 11 , further comprising:
determining a current time of day;
accessing historical data associated with similar times of day; and
wherein determining whether the user intends to open the garage door further includes comparing the user's current appearance with the user's previous appearances at similar times of day.

15. The method of claim 11 , further comprising:
receiving audio data from a microphone mounted to the vehicle;
analyzing, by the door control system, the audio data to determine words spoken by the user; and
wherein determining whether the user intends to open the garage door is further based on the words spoken by the user.

16. A method comprising:
receiving image data from a camera mounted to a vehicle;
analyzing, by a door control system, the image data to determine whether a user is proximate the vehicle; and
responsive to determining that a user is proximate the vehicle, determining whether the user intends to open a garage door based on the image data, wherein determining whether the user intends to open a garage door includes:
analyzing the user's current appearance based on the image data; and
determine whether the user intends to open the garage door based on the user's current appearance,

wherein analyzing the user's current appearance includes at least one of analyzing attire worn by the user and determining whether the attire worn by the user indicates that the user intends to drive the vehicle out of the garage.

17. A method comprising:
receiving image data from a camera mounted to a vehicle;
analyzing, by a door control system, the image data to determine whether a user is proximate the vehicle;
responsive to determining that a user is proximate the vehicle, determining whether the user intends to open a garage door based on the image data;
determining that the user unlocked at least one vehicle door; and
responsive to determining that the user unlocked at least one vehicle door, opening the garage door.
