Abstract

A driving style evaluation system includes a processor receiving driving data associated with at least one driving style category during operations performed by a driver during a first driving mode, the processor determining a preferred driving style for each of the at least one driving style categories based on the driving data. Also included is a controller configured to execute commands associated with the preferred driving style during operation of the vehicle in a second driving mode.

First claim

Having thus described the invention, it is claimed:

1 . A driving style evaluation system comprising:
a processor receiving driving data associated with at least one driving style category during operations performed by a driver during a first driving mode, the processor determining a preferred driving style for each of the at least one driving style categories based on the driving data; and a controller configured to execute commands associated with the preferred driving style during operation of the vehicle in a second driving mode.

2 . The driving evaluation system of claim 1 , wherein the first driving mode is a manual driving mode of an autonomous or semi-autonomous vehicle and the second driving mode is an autonomous or semi-autonomous driving mode of the vehicle.

3 . The driving evaluation system of claim 1 , wherein the at least one driving style category is at least one of acceleration, deceleration, steering, and following distance.

4 . The driving evaluation system of claim 1 , wherein the preferred driving style is determined in a plurality of driving condition categories.

5 . The driving evaluation system of claim 4 , wherein the plurality of driving condition categories is at least one of weather conditions, traffic density, driving surface terrain, and pedestrian population.

6 . A method of evaluating a driving style comprising:
recording driving data associated with a driving style category during operation of an autonomous or semi-autonomous vehicle by a driver during a manual driving mode of the vehicle; processing the driving data; comparing the driving data to a plurality of classifications of the driving style category; and classifying one of the plurality of classifications of the driving style category as a preferred driving style.

7 . The method of claim 6 , further comprising executing commands associated with the preferred driving style during operation of the vehicle in an autonomous or semi-autonomous driving mode.

8 . The method of claim 6 , wherein the driving style category is one of a plurality of driving style categories.

9 . The method of claim 8 , wherein the plurality of driving style categories comprises at least two of acceleration, deceleration, steering, and following distance.

10 . The method of claim 7 , further comprising analyzing driver feedback during operation of the vehicle in the autonomous or semi-autonomous driving mode.

11 . The method of claim 10 , wherein the driver feedback is explicit feedback intentionally provided by the driver.

12 . The method of claim 10 , wherein the driver feedback is implicit feedback unintentionally provided by the driver.

13 . The method of claim 12 , wherein the implicit feedback comprises analysis of a facial expression.

14 . The method of claim 10 , wherein the driver feedback is at least one of explicit and implicit feedback provided by the driver.

15 . The method of claim 14 , further comprising modifying the preferred driving style based on the analysis of the explicit and/or the implicit feedback.

16 . A method of evaluating a driving style comprising:
analyzing driver feedback during operation of an autonomous or semi-autonomous vehicle in an autonomous or semi-autonomous driving mode; determining a preferred driving style based on the analyzed driver feedback; and executing commands associated with the preferred driving style during operation of the vehicle in the autonomous or semi-autonomous driving mode.

17 . The method of claim 16 , wherein the driver feedback is explicit feedback intentionally provided by the driver.

18 . The method of claim 16 , wherein the driver feedback is implicit feedback unintentionally provided by the driver.

19 . The method of claim 18 , wherein the implicit feedback comprises analysis of a facial expression.

20 . The method of claim 16 , wherein the driver feedback is a combination of explicit and implicit feedback provided by the driver.
