Abstract

An automotive vehicle may include at least one controller configured to monitor a plurality of parameters representing a driver'"'"'s dynamic control of the vehicle and to establish a reference range based on values of the monitored parameters during a first time period. The at least one controller may be further configured to detect a change in driver behavior condition when, during a second time period, a parameter derived from the monitored parameters falls outside of the reference range, and in response to detecting the change in driver behavior condition, to alter a response of the vehicle to driver inputs or to generate output representing a recommendation to alter a response of the vehicle to driver inputs.

Claims

1. A vehicle comprising:

a controller configured to (i) monitor parameters representing a driver'"'"'s dynamic control of the vehicle, (ii) derive a reference range from values of the monitored parameters during a first time period, (iii) detect a change in behavior when, during a second time period, a parameter derived from the monitored parameters falls outside of the reference range, and (iv) in response to detecting the change in behavior, alter a response of the vehicle to driver inputs.

2. The vehicle of claim 1 wherein the controller is further configured to, during the second time period, categorize aspects of the driver'"'"'s dynamic control of the vehicle based on the monitored parameters or the parameter derived from the monitored parameters.

3. The vehicle of claim 2 wherein the controller is further configured to determine a manner in which to alter the response of the vehicle to driver inputs based on the categorization.

4. The vehicle of claim 1 wherein altering a response of the vehicle to driver inputs includes selecting an accelerator pedal transition mapping.

5. The vehicle of claim 1 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing an accelerator pedal sensitivity.

6. The vehicle of claim 1 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing a steering wheel sensitivity.

7. The vehicle of claim 1 wherein establishing a reference range based on values of the monitored parameters includes determining at least one of a mean and variance of the parameter derived from the monitored parameters.

8. The vehicle of claim 1 wherein the reference range is defined by a mean and variance of the parameter derived from the monitored parameters.

9. An automotive vehicle comprising:

at least one controller configured to (i) monitor a plurality of parameters representing a driver'"'"'s dynamic control of the vehicle, (ii) establish a reference range based on values of the monitored parameters during a first time period, (iii) detect a change in driver behavior condition when, during a second time period, a parameter derived from the monitored parameters falls outside of the reference range, and (iv) in response to detecting the change in driver behavior condition, generate output representing a recommendation to alter a response of the vehicle to driver inputs.

10. The vehicle of claim 9 wherein the at least one controller is further configured to receive input representing a response to the recommendation and to alter the response of the vehicle to driver inputs if the response is affirmative.

11. The vehicle of claim 10 wherein altering a response of the vehicle to driver inputs includes selecting an accelerator pedal transition mapping.

12. The vehicle of claim 10 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing an accelerator pedal sensitivity.

13. The vehicle of claim 10 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing a steering wheel sensitivity.

14. The vehicle of claim 9 wherein the at least one controller is further configured to categorize aspects of the driver'"'"'s dynamic control of the vehicle based on the monitored parameters or the parameter derived from the monitored parameters.

15. The vehicle of claim 14 wherein the at least one controller is further configured to determine a manner in which to alter the response of the vehicle to driver inputs based on the categorization.

16. A method for tuning a vehicle'"'"'s response to driver inputs comprising:

monitoring a plurality of parameters representing a driver'"'"'s dynamic control of the vehicle;

establishing a reference range based on values of the monitored parameters during a first time period;

detecting a change in driver behavior condition when, during a second time period, a parameter derived from the monitored parameters falls outside of the reference range; and

in response to detecting the change in driver behavior condition, (i) generating output representing a recommendation to alter a response of the vehicle to driver inputs or (ii) altering a response of the vehicle to driver inputs.

17. The method of claim 16 wherein altering a response of the vehicle to driver inputs includes selecting an accelerator pedal transition mapping.

18. The method of claim 16 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing an accelerator pedal sensitivity.

19. The method of claim 16 wherein altering a response of the vehicle to driver inputs includes increasing or decreasing a steering wheel sensitivity.
