Abstract

A system for enabling a driver to input a vehicle control instruction into an autonomous vehicle controller while the autonomous vehicle controller is operating a vehicle in either an autonomous mode or a semi-autonomous mode is disclosed herein. The system includes, but is not limited to, a sensor that is configured to detect a driver input and to generate a signal corresponding with the driver input. The system further includes a communication sub-system communicatively coupled with the sensor and configured to be communicatively coupled with the autonomous vehicle controller. The communication sub-system is further configured to deliver the signal from the sensor to the autonomous vehicle controller. The autonomous vehicle controller controls the vehicle in a manner that corresponds with the driver input when the autonomous vehicle controller receives the signal.

Claims

1. A system for enabling a driver to input a vehicle control instruction into an autonomous vehicle controller while the autonomous vehicle controller is operating a vehicle in either an autonomous mode or a semi-autonomous mode, the system comprising:

a sensor configured to detect a driver input and to generate a signal corresponding with the driver input; and

a communication sub-system communicatively coupled with the sensor and configured to be communicatively coupled with the autonomous vehicle controller, the communication sub-system being further configured to deliver the signal from the sensor to the autonomous vehicle controller,

wherein the autonomous vehicle controller controls the vehicle in a manner corresponding with the driver input when the autonomous vehicle controller receives the signal.

2. The system of claim 1, wherein the sensor comprises a touch sensitive surface configured to detect a gesture.

3. The system of claim 2, wherein the touch sensitive surface is mounted on a rim of a steering wheel of the vehicle.

4. The system of claim 2, wherein the gesture comprises movement of a touching member along the touch sensitive surface in a direction corresponding with a desired direction of lateral movement of the vehicle within a traffic lane.

5. The system of claim 2, wherein the gesture comprises movement of a touching member along the touch sensitive surface in a direction corresponding with a desired acceleration of the vehicle.

6. A system for enabling a driver to input a vehicle control instruction into an autonomous vehicle controller while the autonomous vehicle controller is operating a vehicle in either an autonomous mode or a semi-autonomous mode, the system comprising:

a first sensor configured to detect a driver input and to generate a first signal corresponding with the driver input;

a processor communicatively coupled with the first sensor and adapted to be operatively coupled with the autonomous vehicle controller, the processor configured to obtain the first signal from the first sensor and in response to the first signal, (i) to determine a driver intent based, at least in part, on the first signal, and (ii) to provide the autonomous vehicle controller with a command corresponding with the driver intent,

wherein the autonomous vehicle controller controls the vehicle in a manner corresponding with the command when the autonomous vehicle controller receives the command.

7. The system of claim 6, wherein the first sensor comprises a touch sensitive surface configured to detect a gesture.

8. The system of claim 7, wherein the touch sensitive surface is mounted on a rim of a steering wheel of the vehicle.

9. The system of claim 7, wherein the gesture comprises movement of a touching member along the touch sensitive surface in a direction corresponding with a desired direction of lateral movement of the vehicle within a traffic lane.

10. The system of claim 7 wherein the gesture comprises movement of a touching member along the touch sensitive surface in a direction corresponding with a desired acceleration of the vehicle.

11. The system of claim 7, wherein the command further corresponds with a magnitude of the gesture.

12. The system of claim 7, wherein the processor is further configured to determine whether the gesture was intentionally made by the driver.

13. The system of claim 7, further comprising a memory unit communicatively coupled with the processor, the memory unit configured to store a data file containing information corresponding to the driver input.

14. The system of claim 13, wherein the processor is further configured to determine the driver intent based, at least in part, on the information stored in the data file.

15. The system of claim 14, wherein the memory unit is further configured to contain a plurality of data files for a respective plurality of drivers and wherein the processor is further configured to process and store data files and to determine the driver intent for each driver of the plurality of drivers based, at least in part, on the information stored in the plurality of data files.

16. The system of claim 14, further comprising a second sensor communicatively coupled with the processor, the second sensor configured to detect an environmental condition proximate the vehicle and to generate a second signal corresponding with the environmental condition, wherein the processor is further configured to obtain the second signal from the second sensor and to determine the driver intent based, at least in part, on the second signal.

17. The system of claim 16, wherein the second sensor comprises a proximity sensor.

18. A method for responding to a vehicle control instruction input by a driver into an autonomous vehicle controller while the autonomous vehicle controller is operating a vehicle in either an autonomous mode or a semi-autonomous mode, the method comprising the steps of:

detecting a driver input with a sensor;

generating, with the sensor, a signal corresponding with the driver input;

determining, with a processor, a driver intent based, at least in part, on the signal;

generating, with the processor, a command that corresponds with the driver intent;

providing the command to the autonomous vehicle controller; and

controlling the vehicle with the autonomous vehicle controller in a manner that corresponds with the command.

19. The method of claim 18, wherein the step for determining the driver intent includes determining whether the driver input was intentionally provided.

20. The method of claim 18, wherein the step for generating the signal comprises generating the signal such that the signal corresponds with a magnitude of the driver input.
