Abstract

A system for closing carriage doors of a vehicle may include first and second carriage doors configured to open and close via respective first and second actuators. The system may also include a controller configured to receive signals indicative of angles of the first and second doors relative to closed positions. The controller may also be configured to determine respective first and second velocity profiles for the first and second carriage doors based on the angles of the first and second doors. In addition, the controller may be configured to control operation of at least one of the first and second actuators based on the first and second angles, such that the first carriage door and the second carriage door stay farther apart from one another than a predetermined threshold distance while closing.

First claim

What is claimed is:

1. A system for closing carriage doors of a vehicle, the system comprising:
a first carriage door configured to be opened and closed via a first actuator relative to a side of the vehicle on which the first carriage door is attached;
a second carriage door configured to be opened and closed via a second actuator relative to the side of the vehicle on which the second carriage door is attached; and
a controller configured to:
receive signals indicative of a first angle relative to the side of the vehicle at which the first carriage door is oriented;
receive signals indicative of a second angle relative to the side of the vehicle at which the second carriage door is oriented;
determine a first velocity profile for the first carriage door based on the first angle and the second angle;
determine a second velocity profile for the second carriage door based on the first angle and the second angle; and
control operation of at least one of the first and second actuators based on the first and second angles, such that the first carriage door and the second carriage door stay farther apart from one another than a predetermined threshold distance while closing.

2. The system of claim 1 , further comprising at least one sensor communicatively coupled to the controller and configured to send signals indicative of the first angle and the second angle.

3. The system of claim 1 , wherein the first carriage door is located closer to a front portion of the vehicle than the second carriage door, and wherein the second carriage door is located closer to a rear portion of the vehicle than the first carriage door.

4. The system of claim 3 , wherein the first carriage door closes before the second carriage door to prevent the first carriage door and the second carriage door from being closer to one another than the predetermined threshold distance while closing.

5. The system of claim 3 , wherein the second carriage door closes before the first carriage door to prevent the first carriage door and the second carriage door from being closer to one another than the predetermined threshold distance while closing.

6. The system of claim 1 , wherein the first carriage door closes before the second carriage door in response to the first angle being less than the second angle.

7. The system of claim 1 , wherein the second carriage door closes before the first carriage door in response to the second angle being less than the first angle.

8. The system of claim 1 , wherein first carriage door and the second carriage door begin moving toward a closed position at substantially the same speed.

9. The system of claim 8 , wherein movement of the first carriage door decreases in velocity relative to a velocity of movement of the second carriage door when the first carriage door and the second carriage door are closing and are less than thirty degrees from the closed position.

10. The system of claim 9 , wherein the first carriage door moves into the closed position after the second carriage door has moved into the closed position.

11. A method for closing carriage doors of a vehicle, the method comprising:
receiving, via a controller, signals indicative of a first angle, wherein the first angle is an angle at which a first carriage door is opened relative to a side of the vehicle on which the carriage doors are attached;
receiving, via the controller, signals indicative of a second angle, wherein the second angle is an angle at which a second carriage door is opened relative to the side of the vehicle on which the carriage doors are attached;
determining, via the controller, the first and second angle;
determining, via the controller, a velocity profile for the first carriage door based on the first angle and the second angle;
determining, via the controller, a velocity profile for the second carriage door based on the first angle and the second angle; and
controlling, via the controller, operation of at least one of a first actuator configured to open and close the first carriage door relative to the side of the vehicle on which the carriage doors are attached, and a second actuator configured to open and close the second carriage door relative to the side of the vehicle on which the carriage doors are attached, the operation being based on the first and second angles, such that the first carriage door and the second carriage door stay farther apart from one another than a predetermined threshold distance while closing.

12. The method of claim 11 , further comprising sending via at least one sensor communicatively coupled to the controller, the signals indicative of the first angle and the signals indicative of the second angle.

13. The method of claim 11 , further comprising controlling operation of at least one of the first and second actuators, such that the first carriage door closes before the second carriage door to prevent the first carriage door and the second carriage door from being closer to one another than the predetermined threshold distance while closing.

14. The method of claim 11 , further comprising controlling operation of at least one of the first and second actuators, such that the second carriage door closes before the first carriage door to prevent the first carriage door and the second carriage door from being closer to one another than the predetermined threshold distance while closing.

15. The method of claim 11 , further comprising controlling operation of at least one of the first and second actuators, such that the first carriage door closes before the second carriage door in response to the first angle being less than the second angle.

16. The method of claim 11 , further comprising controlling operation of at least one of the first and second actuators, such that the second carriage door closes before the first carriage door in response to the second angle being less than the first angle.

17. The method of claim 11 , further comprising controlling operation of at least one of the first and second actuators, such that the first carriage door and the second carriage door begin moving toward a closed position at substantially the same speed.

18. The method of claim 17 , further comprising controlling operation of at least one of the first and second actuators, such that the first carriage door decreases in velocity relative to a velocity of the second carriage door when the first carriage door and the second carriage door are closing and are less than thirty degrees from the closed position.

19. The method of claim 18 , further comprising controlling operation of at least one of the first and second actuators, such that the first carriage door moves into the closed position after the second carriage door has moved into the closed position.
