System and method for gesture-based control of a vehicle door
First Claim
Patent Images
1. A vehicle, comprising:
- a door rotatably coupled with a door opening;
a power assist device coupled between the door and the door opening;
a sensor; and
a controller;
receiving a signal from the sensor;
identifying a first gesture by a user from a second set of data within the signal;
interpreting the first gesture as one of a door open command and a door close command by comparison of a movement of a tracked body part of a user to stored data relating respectively to the door open command and the door close command, wherein the stored data includes a first movement path, a first tolerance range from the first movement path, and a second tolerance range from the first movement path that is larger than the first tolerance range and the comparison of the movement of the tracked body part to the stored data includes determining if the movement is within the first tolerance range from the first movement path;
adjusting the first movement path in response to the movement being outside of the first tolerance range and within the second tolerance range on a first side of the first movement path over a predetermined number of repetitions; and
causing the power assist device to move the door to one of an open condition with respect to the opening in response to the door open command and a closed condition with respect to the door in response to the door close command.

Abstract
A control system for a vehicle door includes a power assist device coupled between a door and a door opening of the vehicle and a sensor. The system further includes a controller that receives a signal from the sensor, identifies a recognized user from image data within the signal, interprets a control gesture by the recognized user from video data within the signal, and causes the power assist device to move the door in response to the control gesture.

1. A vehicle, comprising:
-
a door rotatably coupled with a door opening; a power assist device coupled between the door and the door opening; a sensor; and a controller; receiving a signal from the sensor; identifying a first gesture by a user from a second set of data within the signal; interpreting the first gesture as one of a door open command and a door close command by comparison of a movement of a tracked body part of a user to stored data relating respectively to the door open command and the door close command, wherein the stored data includes a first movement path, a first tolerance range from the first movement path, and a second tolerance range from the first movement path that is larger than the first tolerance range and the comparison of the movement of the tracked body part to the stored data includes determining if the movement is within the first tolerance range from the first movement path; adjusting the first movement path in response to the movement being outside of the first tolerance range and within the second tolerance range on a first side of the first movement path over a predetermined number of repetitions; and causing the power assist device to move the door to one of an open condition with respect to the opening in response to the door open command and a closed condition with respect to the door in response to the door close command. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method for controlling opening and closing of a vehicle door, comprising:
-
receiving a signal from a sensor; identifying a recognized user from a first set of data within the signal; upon identifying a first gesture by a user from within the signal; comparing the first gesture to stored data relating to a door movement command, the stored data including a first movement path and first and second tolerance ranges from the first movement path; interpreting the first gesture as the door movement command, if the gesture is within the first tolerance range from the first movement path; and causing a power assist device to move the door in a manner corresponding with the door movement command; and upon identifying a first unknown gesture by the recognized user; receiving a command to designate the first unknown gesture as the door movement command; deriving a first movement path based on the first unknown gesture; storing the first movement path in memory in association with the door movement command; and adjusting the first movement path based on the first gesture being within a repeated deviation from the first movement path. - View Dependent Claims (10, 11, 12)

13. A vehicle, comprising:
-
a door rotatably coupled with a door opening; a power assist device coupled between the door and the door opening; a sensor; and a controller; receiving a signal from the sensor; identifying a recognized user from a first set of data within the signal; identifying a first gesture by the recognized user from a second set of data within the signal; interpreting the first gesture as one of a door open command and a door close command by comparison of a movement of a tracked body part of a user to stored data relating respectively to the door open command and the door close command, wherein the stored data includes a first movement path, a first tolerance range from the first movement path, and a second tolerance range from the first movement path that is larger than the first tolerance range and the comparison of the movement of the tracked body part to the stored data includes determining if the movement is within the first tolerance range from the first movement path; storing data including a second movement path in response to the movement being outside of the first tolerance range and within the second tolerance range on a first side of the first movement path over a predetermined number of occurrences; and causing the power assist device to move the door to one of an open condition with respect to the opening in response to the door open command and a closed condition with respect to the door in response to the door close command. - View Dependent Claims (14, 15, 16, 17, 18, 19)
