Abstract

A vehicle includes a sensor system outputting one or more signals and an electronic control unit communicatively coupled to the sensor system. The electronic control unit may be configured to detect a target vehicle external to the vehicle based on the one or more signals output by the sensor system, identify the detected target vehicle, determine rating information for at least one of the target vehicle and a driver of the target vehicle, predict at least one action of the target vehicle based on the rating information, and effect one or more changes to the vehicle based on the predicted at least one action of the target vehicle.

Claims

1. A vehicle comprising:

a sensor system outputting one or more signals; and

an electronic control unit communicatively coupled to the sensor system and configured to;

detect a target vehicle external to the vehicle based on the one or more signals output by the sensor system;

identify the detected target vehicle;

determine rating information for at least one of the target vehicle and a driver of the target vehicle;

predict at least one action of the target vehicle based on the rating information; and

affect one or more changes to the vehicle based on the predicted at least one action of the target vehicle,

wherein the rating information is based on one or more user inputs.

2. The vehicle of claim 1 wherein effecting the one or more changes to the vehicle comprises one or more of altering one or more vehicle settings and implementing one or more driving maneuvers.

3. The vehicle of claim 2 wherein the one or more driving maneuvers comprise one or more of adjusting the vehicle position in a lane, changing lanes, passing the target vehicle, adjusting a distance between the vehicle and the target vehicle, braking, accelerating, decelerating, swerving, and stopping.

4. The vehicle of claim 3 wherein the vehicle is configured to execute the one or more driving maneuvers from one or more lists with respect to the rating information of the target vehicle or the driver of the target vehicle.

5. The vehicle of claim 2 wherein altering one or more vehicle settings of the vehicle comprises one or more of altering a preprogrammed vehicle route, planning a route to pass the target vehicle, adjusting engine parameters, adjusting one or more regenerative braking parameters, adjusting one or more powertrain control parameters, adjusting one or more accelerator pedal settings, and adjusting the responsiveness of the vehicle acceleration.

6. The vehicle of claim 5 wherein the vehicle is configured to enable at least one of a manufacturer, an end user, or an intermediate user to define one or more lists of settings to be altered with respect to the rating information of the target vehicle or the driver of the target vehicle and to alter such settings with respect to the rating information of the target vehicle or the driver of the target vehicle.

7. The vehicle of claim 1 wherein the rating information is determined from both an identity of the target vehicle and an identity of the driver of the target vehicle.

21. The vehicle of claim 1, wherein the rating information is based on one or more user inputs that include one or more of a textual based rating and a number based rating.

22. The vehicle of claim 21, wherein one or more users of the vehicle input the user input on demand or the vehicle prompts the one or more users of the vehicle to input the user input.

8. An electronic control unit configured to:

detect a target vehicle external to a vehicle based on one or more signals output by a sensor system;

identify the detected target vehicle;

determine rating information for at least one of the target vehicle and a driver of the target vehicle;

predict at least one action of the target vehicle based on the rating information; and

effect one or more changes to the vehicle based on the predicted at least one action of the target vehicle,

wherein the rating information is based on one or more user inputs.

9. The electronic control unit of claim 8 wherein effecting the one or more changes to the vehicle comprises one or more of altering one or more vehicle settings and implementing one or more driving maneuvers.

10. The electronic control unit of claim 9 wherein the one or more driving maneuvers comprise one or more of adjusting the vehicle position in a lane, changing lanes, passing the target vehicle, adjusting a distance between the vehicle and the target vehicle, braking, accelerating, decelerating, swerving, and stopping.

11. The electronic control unit of claim 10 wherein the electronic control unit is configured to execute the one or more driving maneuvers from one or more lists with respect to the rating information of the target vehicle or the driver of the target vehicle.

12. The electronic control unit of claim 9 wherein altering one or more vehicle settings of the vehicle comprises one or more of altering a preprogrammed vehicle route, planning a route to pass the target vehicle, adjusting engine parameters, adjusting one or more regenerative braking parameters, adjusting one or more powertrain control parameters, adjusting one or more accelerator pedal settings, and adjusting the responsiveness of the vehicle acceleration.

13. The electronic control unit of claim 8 wherein the electronic control unit effects a first change to the vehicle if the rating information meets a particular criteria and the electronic control unit effects a second change if the rating does not meet a particular criteria.

14. The electronic control unit of claim 8 wherein the rating information is determined from both an identity of the target vehicle and an identity of the driver of the target vehicle.

15. A method of effecting one or more changes to a vehicle comprising:

detecting a target vehicle external to the vehicle based on the one or more signals output by a sensor system;

identifying the detected target vehicle;

determining rating information for at least one of the target vehicle and a driver of the target vehicle;

predicting at least one action of the target vehicle based on the rating information; and

effecting one or more changes to the vehicle based on the predicted at least one action of the target vehicle,

wherein the rating information is based on one or more user inputs.

16. The method of claim 15 wherein effecting the one or more changes to the vehicle comprises one or more of altering one or more vehicle settings and implementing one or more driving maneuvers.

17. The method of claim 16 wherein the one or more driving maneuvers comprise one or more of adjusting the vehicle position in a lane, changing lanes, passing the target vehicle, adjusting a distance between the vehicle and the target vehicle, braking, accelerating, decelerating, swerving, and stopping.

18. The method of claim 16 wherein altering one or more vehicle settings of the vehicle comprises one or more of altering a preprogrammed vehicle route, planning a route to pass the target vehicle, adjusting engine parameters, adjusting one or more regenerative braking, adjusting one or more powertrain control parameters, adjusting one or more accelerator pedal settings, and adjusting the responsiveness of the vehicle acceleration.

19. The method of claim 16 wherein the electronic control unit effects a first change or no change to the vehicle if the rating information meets a particular criteria and the electronic control unit effects a second change if the rating does not meet a particular criteria.

20. The method of claim 15 wherein the rating information is determined from both an identity of the target vehicle and an identity of the driver of the target vehicle.
