Abstract

Example vehicle unlocking systems and methods are described. In one implementation, a method detects a vehicle access device within a predetermined distance of a vehicle and determines a geographic location of the vehicle. The method also detects a time of day and determines previous door unlocking behavior associated with the vehicle access device. A vehicle access point is selected for unlocking based on the geographic location, time of day, and previous door unlocking behavior.

First claim

The invention claimed is:

1. A method comprising:
detecting a vehicle access device within a predetermined distance of a vehicle;
determining a geographic location of the vehicle;
detecting a time of day;
determining previous door unlocking behavior associated with the vehicle access device;
selecting, using one or more processors, a vehicle access point to unlock based on the geographic location, time of day, and previous door unlocking behavior;
unlocking the selected vehicle access point;
determining whether the user opened the selected vehicle access point; and
updating the door unlocking behavior associated with the vehicle access device based on whether the user opened the selected vehicle access point.

2. The method of claim 1 , further comprising detecting a day of the week, wherein selecting a vehicle access point to unlock is further based on the day of the week.

3. The method of claim 2 , further comprising selecting multiple vehicle access point to unlock based on the geographic location, time of day, day of the week, and previous door unlocking behavior.

4. The method of claim 1 , further comprising preventing unlocking of the selected vehicle access point if a user override contradicts unlocking of the selected vehicle access point.

5. The method of claim 1 , further comprising determining a direction from which the vehicle access device is approaching the vehicle, wherein selecting a vehicle access point to unlock is further based on the direction from which the vehicle access device is approaching the vehicle.

6. The method of claim 5 , further comprising predicting an intent of a user carrying the vehicle access device based on the geographic location, time of day, previous door unlocking behavior, and direction from which the vehicle access device is approaching the vehicle.

7. The method of claim 1 , wherein the vehicle access device is one of a key fob, a smartphone, a portable computing device, a tablet computer, and a smart watch.

8. The method of claim 1 , further comprising automatically opening the selected vehicle access point subsequent to unlocking the selected access point.

9. A method comprising:
detecting a vehicle access device within a predetermined distance of a vehicle;
determining a geographic location of the vehicle;
detecting a time of day;
determining previous door unlocking behavior associated with the vehicle access device;
selecting, using one or more processors, a vehicle access point to unlock based on the geographic location, time of day, and previous door unlocking behavior; and
detecting an environmental condition proximate the vehicle, wherein selecting a vehicle access point to unlock is further based on the environmental condition.

10. The method of claim 9 , wherein the environmental condition includes at least one of a temperature, an ambient light level, and a precipitation condition.

11. The method of claim 1 , wherein the vehicle access point is one of a vehicle door, a trunk, a tailgate, a sliding door, a hatch, a hood, and a gas tank refill door.

12. An apparatus comprising:
a vehicle access device;
a vehicle lock manager forming part of a vehicle and configured to communicate with the vehicle access device and detect the presence of the vehicle access device within a predetermined distance of the vehicle, the vehicle lock manager comprising a processing device programmed to:
detect a vehicle access device within a predetermined distance of the vehicle;
determine a geographic location of the vehicle;
detect a time of day;
determine previous door unlocking behavior associated with the vehicle access device;
select a vehicle access point to unlock based on the geographic location, time of day, and previous door unlocking behavior;
unlock the selected vehicle access point;
determine whether the user opened the selected vehicle access point; and
update the door unlocking behavior associated with the vehicle access device based on whether the user opened the selected vehicle access point.

13. The apparatus of claim 12 , further comprising an override manager configured to prevent unlocking of the at least one vehicle access point.

14. The apparatus of claim 12 , further comprising an environmental data manager configured to access data associated with environmental conditions proximate the vehicle.

15. A vehicle comprising:
a plurality of doors, each of the plurality of doors having an associated door lock; and
a vehicle lock manager coupled to the door locks associated with the plurality of doors, the vehicle lock manager configured to communicate with a vehicle access device, the vehicle lock manager including a processing device programmed to:
detect a vehicle access device within a predetermined distance of the vehicle;
determine a geographic location of the vehicle;
detect a time of day;
determine previous door unlocking behavior associated with the vehicle access device;
select a vehicle access point to unlock based on the geographic location, time of day, and previous door unlocking behavior;
unlock the selected vehicle access point;
determine whether the user opened the selected vehicle access point; and
update the door unlocking behavior associated with the vehicle access device based on whether the user opened the selected vehicle access point.

16. The vehicle of claim 15 , the vehicle lock manager further comprising an override manager configured to prevent unlocking of the at least one vehicle door.
