Abstract

A vehicle interface input receiving method comprises operating a controller to selectively enter or refrain from entering a user input device controlling mode. While in the user input device controlling mode, the method determines a presence of first and second contact conditions at first and second predetermined locations, respectively, with the first contact condition being on a vehicle steering wheel, and controls a user input device to change from a deactivated state to an activated state in response to the simultaneous existence of the first and second contact conditions. Also, an indicator provides an indication of the activated state, and the user input device is maintained in the activated state while the first contact condition continues to exist. The user input device provides input to the controller in the activated state and refrains from providing such input in the deactivated state, and afterward returns to the deactivated state.

First claim

What is claimed is:

1. A vehicle interface input receiving method comprising:
operating a controller to enter a user input device controlling mode;
operating the controller to determine a presence of a first contact condition representing contract at a first predetermined location on a vehicle steering wheel and a second contact condition at a second predetermined location while the controller is operating in the user input device controlling mode;
operating the controller to control a user input device to change from a deactivated state to an activated state in response to the first and second contact conditions simultaneously existing at the first and second predetermined locations, respectively, while the controller is operating in the user input device controlling mode;
operating an indicator to provide an indication of the activated state while the user input device is in the activated state;
operating the controller to maintain the user input device in the activated state while the controller determines that the first contact condition continues to exist at the first predetermined location while the controller is operating in the user input device controlling mode;
operating the user input device to provide input to the controller in the activated state and to refrain from providing input to the controller in the deactivated state while the controller is operating in the user input device controlling mode; and
operating the controller to control the user input device to return to the deactivated state after receiving the input from the user input device while the controller is operating in the user input device controlling mode.

2. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the controller to determine the presence of the second contact condition includes determining the presence of the second contact condition at a location on the steering wheel which corresponds to the second predetermined location, such that the first and second predetermined locations are interchangeable.

3. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the controller to determine the presence of the second contact condition includes determining the presence of the second contact condition at a location apart from the steering wheel which corresponds to the second predetermined location.

4. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the user input device includes operating a gesture recognition device.

5. The vehicle interface input receiving method according to claim 4 , wherein
the operating of the indicator includes operating a display to demonstrate at least one gesture recognizable as input by the gesture recognition device.

6. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the controller to control the user input device to change from the deactivated state to the activated state includes operating the controller to control the user input device to change from the deactivated state to the activated state in response to the first and second contact conditions simultaneously existing at the first and second predetermined locations, respectively, followed by the controller determining that the second contact condition ceases to exist at the second predetermined location after a predetermined duration of time has elapsed from when the controller initially determined simultaneous existence of the first and second contact conditions at the first and second predetermined locations, respectively, while the controller is operating in the user input device controlling mode.

7. The vehicle interface input receiving method according to claim 6 , further comprising
operating the controller to control the user input device to remain in the deactivated state upon the second contact condition ceasing to exist at the second predetermined location before expiration of the predetermined duration of time, while the controller is operating in the user input device controlling mode; and
operating the indicator to provide an indication of the deactivated state.

8. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the controller to control the user input device to return from the activated state to the deactivated state includes operating the controller to control the user input device to return to the deactivated state upon the controller determining that the first contact condition ceases to exist at the first predetermined location while the controller is operating in the user input device controlling mode; and
operating the indicator to provide an indication of the deactivated state of the user input device upon the user input device returning to the deactivated state.

9. The vehicle interface input receiving method according to claim 1 , further comprising
operating the controller to select at least one of a plurality of possible contact locations as at least one of the first and second predetermined locations in response to a user instruction.

10. The vehicle interface input receiving method according to claim 1 , further comprising
operating the controller to set at least one of the first and second predetermined locations based on a vehicle component characteristic including at least one of driver seat position, steering wheel position and occupant detection.

11. The vehicle interface input receiving method according to claim 1 , wherein
the presence of the second contact condition at the second predetermined location includes at least one of a physical presence of an object proximate to the second predetermined location, a presence of a visual characteristic directed toward the second predetermined location and a presence of an audio characteristic received at the second predetermined location.

12. The vehicle interface input receiving method according to claim 1 , further comprising
operating a haptic indication device to provide a haptic indication as an indication of the first contact condition at the first predetermined location.

13. The vehicle interface input receiving method according to claim 1 , further comprising
operating a haptic indication device to provide a respective haptic indication of each input received by the user input device.

14. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the indicator includes operating at least one of a haptic indication device to provide a haptic indication, a display to provide a visual indication and an audio system to provide an audio indication.

15. The vehicle interface input receiving method according to claim 1 , wherein
the operating of the controller to determine the presence of the first and second contact conditions includes operating the controller to determine at least one of the presence of the first contact condition at the first predetermined location and the second contact condition at the second predetermined location based on a detected proximity of a user wearable device to at least a respective one of the first and second predetermined locations.

16. The vehicle interface input receiving method according to claim 15 , wherein
the operating of the indicator includes operating a haptic indication device on the wearable device to provide the indication of the activated state as a haptic indication.

17. The vehicle interface input receiving method according to claim 1 , further comprising
operating the controller to refrain from enterin
