Abstract

Methods and systems are provided for a vehicle. The method comprises activating a direction indicator on a vehicle responsive to receiving a user activation input and determining when the vehicle has completed a direction changing maneuver (e.g., lane change or turn). Thereafter, the direction indicator is automatically deactivated responsive to determining that the maneuver has been completed. The system comprises a user activation device and a processor configured to activate one or more of a plurality of vehicular direction indicators responsive to a user activation signal. The processor is also coupled to a plurality of vehicle sensors providing movement data related to the vehicle to the processor. By processing the movement data, the processor automatically deactivates the vehicle direction indicators upon determination that the vehicle has completed a maneuver (e.g., lane change or turn).

Claims

1. A method for indicating vehicular direction, comprising:

activating a direction indicator on a vehicle via a processor responsive to receiving a user activation input;

determining via the processor when the vehicle has completed a lane change maneuver; and

deactivating the direction indicator responsive to the processor determination that the lane change maneuver has completed.

2. The method of claim 1, which includes the step of deactivating the direction indicator responsive to the processor receiving a user deactivation input.

3. The method of claim 1, wherein the determining step further comprises determining when the lane change maneuver has completed by processing global positioning data related to the vehicle.

4. The method of claim 1, wherein the determining step further comprises the processor evaluating vehicle motion data comprising sensor information dynamically selected by the processor.

5. The method of claim 1, wherein the determining step further comprises determining when the lane change maneuver has completed by the processor determining a distance traveled by the vehicle together with one or more of the following group of vehicle factors:

steering angle;

steering angle rate of change;

yaw or yaw rate of change.

6. The method of claim 5, wherein the step of determining the distance traveled by the vehicle further comprises the processor receiving odometer data of the vehicle.

7. The method of claim 5, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity data of the vehicle for a time interval after receiving the user activation input.

8. The method of claim 7, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity and acceleration data of the vehicle for the time interval after receiving the user activation input.

9. The method of claim 7, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity and de-acceleration data of the vehicle for the time interval after receiving the user activation input.

10. The method of claim 5, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing tire rotation for a time interval after receiving the user activation input.

11. A method for indicating vehicular direction, comprising:

activating a direction indicator on a vehicle via a processor responsive to receiving a user activation input;

determining via the processor when the vehicle has completed a turn maneuver; and

deactivating the direction indicator responsive to the processor determination that the turn maneuver has completed.

12. The method of claim 11, which includes the step of deactivating the direction indicator responsive to the processor receiving a user deactivation input.

13. The method of claim 11, wherein the determining step further comprises determining when the turn maneuver has completed by processing global positioning data related to the vehicle.

14. The method of claim 11, wherein the determining step further comprises the processor evaluating vehicle motion data comprising sensor information dynamically selected by the processor.

15. The method of claim 11, wherein the determining step further comprises determining when the turn maneuver has completed by the processor determining a distance traveled by the vehicle together with one or more of the following group of vehicle factors:

steering angle;

steering angle rate of change;

yaw or yaw rate of change.

16. The method of claim 15, wherein the step of determining the distance traveled by the vehicle further comprises the processor receiving odometer data of the vehicle.

17. The method of claim 15, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity data of the vehicle for a time interval after receiving the user activation input.

18. The method of claim 17, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity and acceleration data of the vehicle for the time interval after receiving the user activation input.

19. The method of claim 17, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing velocity and de-acceleration data of the vehicle for the time interval after receiving the user activation input.

20. The method of claim 15, wherein the step of determining the distance traveled by the vehicle further comprises the processor computing tire rotation for a time interval after receiving the user activation input.

a plurality of vehicle sensors operably coupled to the processor for providing motion data related to the vehicle;

wherein, the processor activates at least some of the plurality of vehicle direction indicators responsive to the user activation input and deactivates the vehicle direction indicators when the processor determines from the motion data that the vehicle has completed a maneuver.

22. The system of claim 21, wherein the plurality of vehicular sensors comprise one or more of the following group of sensors:

odometer, steering angle;

steering angle rate of change;

yaw;

yaw rate of change;
