Abstract

A method for tuning a vehicle'"'"'s performance may include measuring a plurality of parameters representing the vehicle'"'"'s current handling condition and the vehicle'"'"'s limit handling condition, determining a margin between the vehicle'"'"'s current handling condition and limit handling condition, characterizing the driver'"'"'s dynamic control of the vehicle based on the margin, and altering at least one tunable vehicle performance parameter based on the characterization.

Claims

1. -11. (canceled)

12. A vehicle comprising:

a sensor arrangement disposed within the vehicle and configured to measure a plurality of parameters representing the vehicle'"'"'s current handling condition and the vehicle'"'"'s limit handling condition; and

at least one controller disposed within the vehicle and configured to determine a margin between the vehicle'"'"'s current handling condition and limit handling condition and to characterize a driver'"'"'s dynamic control of the vehicle based on the margin.

13. The vehicle of claim 12 wherein the at least one controller is further configured to alter at least one tunable vehicle performance parameter based on the characterization.

14. The vehicle of claim 13 wherein the at least one tunable vehicle performance parameter includes at least one of accelerator pedal sensitivity and steering wheel sensitivity.

15. The vehicle of claim 12 wherein characterizing a driver'"'"'s dynamic control of the vehicle based on the margin includes determining, for a specified time interval, the period during which the margin falls within a predetermined range.

16. The vehicle of claim 15 wherein the at least one controller is further configured to receive input specifying the time interval.

17. The vehicle of claim 15 wherein determining, for a specified time interval, the period during which the margin falls within a predetermined range includes determining a complement of the margin.

18. The vehicle of claim 17 wherein determining, for a specified time interval, the period during which the margin falls within a predetermined range includes categorizing a value of the complement of the margin.

19. The vehicle of claim 12 further comprising a haptic driver interface, wherein the at least one controller is further configured to activate the haptic driver interface if the characterization is of a particular type.

20. A vehicle comprising at least one controller configured to characterize a driver'"'"'s dynamic control of the vehicle based on a margin between parameters representing the vehicle'"'"'s current handling condition and limit handling condition and to alter at least one of the vehicle'"'"'s accelerator pedal sensitivity and steering wheel sensitivity based on the characterization.
