Abstract

Arrangements described herein can present a confidence in an autonomous operation of a vehicle to one or more users. At least one operational status for a support system of the vehicle can be acquired. Based on the acquired operational status, a confidence in the autonomous operation of the vehicle can be determined. Responsive to determining the confidence in the autonomous operation of the vehicle, a confidence icon can be caused to be displayed within the vehicle. The confidence icon can include an emoticon that conveys an emotion corresponding to the determined confidence.

First claim

What is claimed is:

1. A method of presenting a confidence in an autonomous operation of a vehicle, the method comprising:
acquiring at least one operational status for at least one support system of the vehicle;
determining, based on the acquired at least one operational status, a first confidence for an autonomous operation for adjusting a speed of the vehicle;
determining, based on the acquired at least one operational status, a second confidence for an autonomous operation for adjusting a position of the vehicle within a lane of a roadway;
responsive to determining the first confidence, causing a first confidence icon to be displayed within the vehicle, the first confidence icon including an emoticon conveying an emotion corresponding to the determined first confidence for the autonomous operation for adjusting the speed of the vehicle;
responsive to determining the second confidence, causing a second confidence icon to be displayed within the vehicle, the second confidence icon including an emoticon conveying an emotion corresponding to the determined second confidence for the autonomous operation for adjusting the position of the vehicle within the lane of the roadway.

2. The method of claim 1 , wherein the at least one support system includes a sensor system of the vehicle.

3. The method of claim 2 , wherein the at least one operational status includes information acquired by the sensor system of the vehicle.

4. The method of claim 2 , wherein the at least one operational status includes a measure of functionality of a portion of the sensor system.

5. The method of claim 1 , wherein the determining the first confidence in the autonomous operation includes determining a first confidence level.

6. The method of claim 5 , wherein the first confidence level has an associated first emoticon.

7. The method of claim 5 , further comprising the step of receiving, from a user, an input assigning an emoticon to one or more confidence levels.

8. The method of claim 1 , further including identifying a first state of autonomous operation of the vehicle, and wherein the determining the first confidence in the autonomous operation of the vehicle is further based on the first state of autonomous operation of the vehicle.

9. A display system for a vehicle configured for an autonomous operation, the system comprising:
at least one support system for the vehicle; and
a processor operatively connected to the at least one support system, the processor being programmed to initiate executable operations comprising:
acquiring at least one operational status for the at least one support system of the vehicle;
determining, based on the acquired at least one operational status, a first confidence for an autonomous operation for adjusting a speed of the vehicle;
determining, based on the acquired at least one operational status, a second confidence for an autonomous operation for adjusting a position of the vehicle within a lane of a roadway;
responsive to determining the first confidence, causing a first confidence icon to be displayed within the vehicle, the first confidence icon including an emoticon conveying an emotion corresponding to the determined first confidence for the autonomous operation for adjusting the speed of the vehicle;
responsive to determining the second confidence, causing a second confidence icon to be displayed within the vehicle, the second confidence icon including an emoticon conveying an emotion corresponding to the determined second confidence for the autonomous operation for adjusting the position of the vehicle within the lane of the roadway.

10. The system of claim 9 , wherein the at least one support system for the vehicle includes a sensor system, and the at least one operational status includes information acquired by the sensor system.

11. The method of claim 1 , wherein the determining the second confidence in the autonomous operation includes determining a second confidence level.

12. The method of claim 11 , wherein the second confidence level has an associated second emoticon.

13. The method of claim 1 , further including identifying a second state of autonomous operation of the vehicle, and wherein the determining the second confidence in the autonomous operation of the vehicle is further based on the second state of autonomous operation of the vehicle.

14. A method of presenting a confidence in an autonomous operation of a vehicle, the method comprising:
acquiring at least one operational status for at least one support system of the vehicle;
determining, based on the acquired at least one operational status, a first confidence for an autonomous operation of the vehicle along a present travel path;
determining, based on the acquired at least one operational status, a second confidence for the autonomous operation of the vehicle along a future travel path;
responsive to determining the first confidence, causing a first confidence icon to be displayed with a map within the vehicle, the first confidence icon including an emoticon conveying an emotion corresponding to the determined first confidence for the autonomous operation of the vehicle along the present travel path, the first confidence icon being presented near the present travel path on the map; and
responsive to determining the second confidence, causing a second confidence icon to be displayed within the vehicle, the second confidence icon including an emoticon conveying an emotion corresponding to the determined second confidence for the autonomous operation of the vehicle along the future travel path, the second confidence icon being displayed near the future travel path on the map.

15. A method of presenting a confidence in an autonomous operation of a vehicle, the method comprising:
acquiring at least one operational status for at least one support system of the vehicle;
determining, based on the acquired at least one operational status, a first confidence for an autonomous operation of the vehicle for a present time;
determining, based on the acquired at least one operational status, a second confidence for the autonomous operation of the vehicle for a second time, the second time being a future time later in time than the present time;
determining, based on the acquired at least one operational status, a third confidence for the autonomous operation of the vehicle at a third time, the third time being later in time than the second time; and
responsive to determining the first, second, and third confidences, causing a first confidence icon, a second confidence icon, and a third confidence icon to be displayed within the vehicle as a function of time,
wherein the first confidence icon including an emoticon conveying an emotion corresponding to the determined first confidence, the second confidence icon including an emoticon conveying an emotion corresponding to the determined second confidence, and the third confidence icon including an emoticon conveying an emotion corresponding to the determined third confidence.
