Abstract

A vehicle user input control system and method is provided having a user input located on a vehicle, a plurality of proximity sensors located proximate the user input, and a controller processing signals generated by the proximity sensors to detect at least one of a trajectory and orientation of a hand proximate to the user input and determining the hand is associated with one of a driver and passenger of the vehicle.

Claims

1. A vehicle user input control system comprising:

a user input device located on a vehicle;

a plurality of proximity sensors arranged in a plurality of rows and columns and located on at least one side of the user input device; and

a controller processing signals generated by the proximity sensors to detect at least one of a trajectory of a hand based on movement and orientation of the hand based on signal patterns generated by the proximity sensors proximate to the user input device, determining the hand is associated with one of a driver and passenger of the vehicle based on the detected at least one of the trajectory and orientation of the hand, and controlling at least one function based on the hand being determined as a driver or passenger.

2. The system of claim 1, wherein the controller limits at least one function when the controller determines the hand is associated with a driver.

3. The system of claim 1, wherein the controller determines the hand is associated with one of a driver and passenger of the vehicle based on a trajectory of the hand moving relative to the plurality of proximity sensors.

4. The system of claim 1, wherein the controller determines the hand is associated with one of a driver and passenger of the vehicle based on the trajectory and the orientation of the hand moving relative to the plurality of proximity sensors.

5. The system of claim 1, wherein the controller determines the orientation of the hand based on the signals compared to known signal patterns.

6. The system of claim 1, wherein the plurality of proximity sensors are located on opposite left and right sides of the user input.

7. The system of claim 1, wherein the user input device comprises a touchscreen.

8. The system of claim 1, wherein the plurality of proximity sensors comprises a plurality of capacitive sensors.

9. A vehicle user input control system comprising:

a user input device located on a vehicle;

a plurality of proximity sensors arranged in a plurality of rows and columns and located proximate the user input device; and

a controller processing signals generated by the proximity sensors to detect at least one of a trajectory of a hand based on movement and orientation of the hand based on signal patterns of digits of the hand generated by the proximity sensors proximate to the user input device, determining the hand is associated with one of a driver and passenger of the vehicle based on at least one of the detected trajectory and orientation of the hand, and controlling at least one function based on the hand being determined as a driver or passenger.

10. The system of claim 9, wherein the controller limits at least one function when the controller determines the hand is associated with a driver.

11. The system of claim 9, wherein the controller determines the hand is associated with one of a driver and passenger of the vehicle based on a trajectory of the hand moving relative to the plurality of proximity sensors.

12. The system of claim 9, wherein the controller determines the hand is associated with one of a driver and passenger of the vehicle based on the trajectory and the orientation of the hand moving relative to the plurality of proximity sensors.

13. The system of claim 9, wherein the controller determines the orientation of the hand based on the signals compared to known signal patterns.

14. The system of claim 9, wherein the plurality of proximity sensors are located on opposite left and right sides of the user input device.

15. The system of claim 9, wherein the user input device comprises a touchscreen.

16. The system of claim 9, wherein the plurality of proximity sensors comprises a plurality of capacitive sensors.

17. A method of determining a user input associated with a driver or passenger of a vehicle, comprising:

sensing a hand proximate to a user input device on a vehicle with a plurality of proximity sensors arranged in a plurality of rows and columns on at least one side of the user input device;

detecting at least one of a trajectory of the hand based movement and orientation of the hand based on signal patterns generated by the proximity sensors;

determining the hand is associated with a driver or passenger of the vehicle based on the detected at least one of a trajectory and orientation; and

controlling at least one function based on the hand being determined as a driver or passenger.
