Abstract

An automatic signaling system for a vehicle having a turn signal light, includes a sensor configured for sensing at least a portion of a lane, and a processor coupled to the sensor, wherein the processor is configured to activate the turn signal light of the vehicle based at least on a signal received from the sensor. A method for activating a turn signal light of a vehicle includes sensing at least a portion of a lane in which the vehicle is traveling, and automatically activating a turn signal light of the vehicle based at least on the sensed portion of the lane.

Claims

1. An automatic signaling system for a vehicle having a turn signal light, comprising:

a sensor configured for sensing at least a portion of a lane; and

a processor coupled to the sensor;

wherein the processor is configured to activate the turn signal light of the vehicle based at least on a signal received from the sensor.

2. The system of claim 1, wherein the processor operates independent of a turning angle of a wheel of the vehicle.

3. The system of claim 1, wherein the sensor comprises an image sensor.

4. The system of claim 3, wherein the image sensor comprises a camera.

5. The system of claim 1, wherein the processor is configured for identifying a lane boundary based at least on the signal received from the sensor.

6. The system of claim 1, wherein the processor is configured to determine a spatial relationship between the vehicle and the lane based at least on the signal received from the sensor.

7. The system of claim 1, wherein said processor is configured to determine an orientation of the vehicle relative to the lane based at least on the signal received from the sensor.

8. The system of claim 1, wherein the processor is coupled to an additional sensor selected from the group consisting of a speed sensor, a light sensor, and a moisture sensor.

9. The system of claim 1, wherein the processor is further configured to activate the turn signal light when the vehicle is traveling above a prescribed speed.

10. The system of claim 1, further comprising a reader for reading data from a key-memory, wherein the processor is further configured to activate the turn signal light of the vehicle based at least on the data.

11. An automatic signaling system, comprising:

a processor having circuitry for receiving a signal from a sensor, the processor configured to automatically activate a turn signal light of a vehicle based on the received signal.

12. The automatic signaling system of claim 11, wherein the processor operates independent of a turning angle of a wheel of the vehicle.

13. The automatic signaling system of claim 12, further comprising the sensor.

14. The automatic signaling system of claim 13, wherein the sensor is configured for sensing a portion of a lane in which the vehicle is traveling.

15. The automatic signaling system of claim 13, wherein the sensor is configured to sense a characteristic of a lane or a lane boundary.

16. An automatic signaling system, comprising:

a camera for obtaining an image of a lane; and

a processor coupled to the camera, the processor configured to activate a turn signal light of a vehicle based on the image.

17. The automatic signaling system of claim 16, wherein the processor operates independent of a turning angle of a wheel of the vehicle.

18. The automatic signaling system of claim 17, wherein the camera is located adjacent a rear view mirror of the vehicle.

19. The automatic signaling system of claim 16, wherein the processor is configured to identify at least a portion of the lane from the image.

20. The automatic signaling system of claim 19, wherein the processor is further configured to determine a spatial relationship between the vehicle and the lane based on the image.
