Abstract

A vehicle control system is configured for autonomous control of at least one actuatable vehicle system or component. The control system includes one or more sensors disposed on a vehicle, and a computing device in communication with the one or more sensors. The computing device is configured to acquire feedback relating to a ride quality feature from a vehicle occupant, identify vehicle control parameters affecting the ride quality feature; identify at least one autonomously controlled vehicle system affecting values of the identified vehicle control parameters; determine revisions to the vehicle control parameters necessary to implement the feedback relating to the ride quality feature; perform control parameter revisions necessary to implement the feedback relating to the ride quality feature, and control operation of the at least one autonomously controlled system or component so as to effect the control parameter revisions needed to implement the feedback.

Claims

1. A vehicle control system configured for autonomous control of at least one actuatable vehicle system or component, the control system comprising:

one or more sensors disposed on a vehicle;

a computing device in communication with the one or more sensors, the computing device including one or more processors for controlling operation of the computing device, and

a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to;

acquire feedback relating to a ride quality feature from a vehicle occupant;

identify vehicle control parameters affecting the ride quality feature;

identify at least one autonomously controlled vehicle system or component affecting values of the identified vehicle control parameters;

determine revisions to the vehicle control parameters necessary to implement the feedback relating to the ride quality feature; and

control operation of the at least one autonomously controlled system or component so as to effect the control parameter revisions needed to implement the feedback.

2. The control system of claim 1 wherein the at least one autonomously controlled vehicle system or component comprises one of an active suspension system, a throttle control system, a steering control system, and a braking control system.

16. A vehicle including a vehicle control system in accordance with claim 1.

3. A computer-implemented method of controlling at least one vehicle system or component, comprising steps of:

acquiring, from a vehicle occupant, feedback relating to a ride quality feature affected by operation of the at least one system or component; and

controlling operation of the at least one system or component responsive to the feedback.

4. The method of claim 3 wherein the step of acquiring feedback comprises a step of prompting selection of a ride quality feature by the vehicle occupant from a menu.

5. The method of claim 3 wherein the step of controlling operation of the at least one system or component comprises a step of determining which vehicle control parameter(s) affect the ride quality feature.

6. The method of claim 5 wherein the step of controlling operation of the at least one system or component further comprises a step of determining how to vary the vehicle control parameter(s) so as to implement the occupant feedback.

7. The method of claim 6 wherein the step of controlling operation of the at least one system or component further comprises a step of varying the control parameter(s) so as to implement occupant feedback.

8. The method of claim 3 further comprising a step of, prior to the step of acquiring feedback, displaying a representation of a previous vehicle ride to the vehicle occupant.

9. The method of claim 8 wherein the step of acquiring feedback comprises the step of prompting the occupant to select a portion of the previous ride on which to provide feedback.

10. The method of claim 9 wherein the step of controlling operation of the at least one system or component comprises a step of retrieving, from a memory, control parameter values pertaining to the selected portion of the previous ride.

11. A computing device configured for communication with at least one autonomously controllable actuatable vehicle system or component, the computing device comprising one or more processors for controlling operation of the computing device, and a memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the memory to:

acquire, from a vehicle occupant, feedback relating to a ride quality feature affected by operation of the at least one autonomously controlled system or component; and

modify autonomous control of the at least one system or component responsive to the feedback.

12. The computing device of claim 11 wherein the one or more processors are configured to execute instructions stored in the memory to determine which vehicle control parameter(s) affect the ride quality feature.

13. The computing device of claim 12 wherein the one or more processors are configured to execute instructions stored in the memory to determine how to vary the vehicle control parameter(s) so as to modify autonomous control of the at least one system or component responsive to the feedback.

14. The computing device of claim 11 wherein the one or more processors are configured to execute instructions stored in the memory to display a representation of a previous vehicle ride to a vehicle occupant.

15. The computing device of claim 14 wherein the one or more processors are configured to execute instructions stored in the memory to prompt selection of a ride quality feature by a vehicle occupant from a menu.

17. A vehicle including a computing device in accordance with claim 11.
