Abstract

Methods and systems are provided for an automated door system for a vehicle. In one example, the method for a vehicle may include operating an automated door system to enable hands-free actuation of a set of door vehicles while the height of the vehicle is not changing and when the vehicle height is changing, suspending operation of the automated door system until the floor has stopped changing height.

First claim

The invention claimed is:

1. A method for a vehicle, comprising:
during a first vehicle condition where a floor height of the vehicle is not changing;
operating an automated door system to enable hands-free actuation of a set of doors of the vehicle; and
during a second vehicle condition where the floor height of the vehicle is changing;
suspending operation of the automated door system until the changing of the floor height is stopped.

2. The method of claim 1 , wherein operating the automated door system includes receiving information from one or more sets of sensor to enable the hands-free actuation of the set of doors and wherein the one or more sets of sensors includes RFID tags and photoelectric sensors.

3. The method of claim 1 , wherein operating the automated door system to enable the hands-free actuation of the set of doors includes actuating unlocking and/or opening of one or more of a side door, a rear door, and a bulkhead door of the vehicle.

4. The method of claim 1 , wherein operating the automated door system during the first vehicle condition includes operating the automated door system when the floor height of the vehicle is at a first position or a second, higher position.

5. The method of claim 1 , wherein suspending operation of the automated door system during the second vehicle condition includes receiving a request to adjust the vehicle to the second vehicle condition, and wherein the request includes a signal from one or more of an input device, a user input, and sensor input.

6. The method of claim 5 , wherein receiving the request from the input device includes receiving the request from one or more of a button in the vehicle, a button on a key fob, and an input to an application on a mobile device.

7. The method of claim 5 , wherein receiving the request from the user input includes receiving the request as one or more of a voice command and a gesture.

8. The method of claim 5 , wherein receiving the request from the sensor input includes receiving the signal at one or more of a motion sensor, a RFID system, a photoelectric system, a key fob proximity to the vehicle, and a camera feed.

9. A method for an automated door system for a vehicle, comprising:
adjusting a floor height of the vehicle between a first height and a second height, the second height higher than the first height, in response to a request from a user;
activating the automated door system at a door when the floor height is held stationary at the first height or the second height; and
upon holding the floor height at the first height;
opening the door at a first speed; and

upon holding the floor height at the second height;
determining a position of the user relative to the door and adjusting the opening of the door based on the position of the user.

10. The method of claim 9 , wherein adjusting the floor height of the vehicle includes varying a distance between a skateboard chassis of the vehicle and a ground surface.

11. The method of claim 9 , wherein activating the automated door system at the door includes enabling automated unlocking and/or opening of the door and wherein the door is one of a side door, a rear door, and a bulkhead door.

12. The method of claim 9 , wherein adjusting the opening of the door based on the position of the user includes opening the door at a second speed, slower than the first speed, in response to the user being within a threshold distance of the door, and wherein the threshold distance is a radius of an arc of the door when the door is swung open.

13. The method of claim 12 , wherein adjusting the opening of the door based on the position of the user includes one or more of suspending opening of the door and providing an alert to the user, until the user is positioned beyond the threshold distance of the door.

14. The method of claim 9 , wherein determining the position of the user relative to the door includes receiving information from one or more of an RFID system and a photoelectric system.

15. The method of claim 9 , wherein activating the automated door system at the door includes determining that a vehicle control unit, the vehicle control unit configured to control the automated door system, is awake and in a stand-by mode.

16. The method of claim 9 , wherein adjusting the floor height of the vehicle includes deactivating the automated door system while the floor height is changing.

17. A system for a vehicle, comprising:
an automated door system activated by one or more of a manual mechanism and a set of sensors; and
a controller configured with executable instructions stored in non-transitory memory that, when executed, cause the controller to:
adjust a floor height of the vehicle in response to a request for a change to the floor height and operate the automated door system according to the floor height and a position of a user relative to a door to be opened, and wherein the automated door system is operated according to the floor height based on adjustment of the floor height between a lower position and a higher position.

18. The system of claim 17 , wherein the lower position is a kneeling position of the vehicle, the kneeling position corresponding to a decreased floor height relative to the floor height when the vehicle is navigating.

19. The system of claim 17 , wherein the manual mechanism includes one or more of a push button at the door, a key, a button at a key fob, and a button at a dashboard of the vehicle.

20. The system of claim 17 , wherein the set of sensors includes one or more of an RFID tag coupled to a RFID sensor and photoelectric sensors.
