Abstract

A vehicle collision warning system including a first sensor configured to generate a first signal indicating an exit condition, a second sensor configured to generate a second signal indicating a traffic condition, an internal warning signal system configured to emit a warning signal to warn a vehicle occupant about a hazard condition, the internal warning signal system including, a warning device configured to emit the warning signal, and a processor configured to receive the first signal from the first sensor, receive the second signal from the second sensor, detect the hazard condition based on the first and second signals, and generate a control signal to cause the warning device to emit the warning signal to warn the vehicle occupant about the hazard condition.

Claims

1. A collision warning system for a vehicle, comprising:

a warning signal system configured to emit a warning signal to warn a vehicle occupant about a hazard condition, the warning signal system comprising;

a warning device configured to emit the warning signal; and

a processor configured to;

determine an exit condition indicating that the vehicle occupant is about to exit the vehicle from a side of the vehicle, wherein determining the exit condition comprises receiving a signal from an exit sensor;

determine a traffic condition indicating a traffic around the vehicle;

detect the hazard condition is on the same side of the vehicle where the occupant is about to exit the vehicle based on the exit condition and the traffic condition; and

in response to the hazard condition having been detected, generate a control signal for transmission to the warning device to emit the warning signal; and

, wherein

the warning device is further configured to receive the control signal and emit a warning signal to warn the vehicle occupant about the hazard condition.

2. The system of claim 1, wherein the exit sensor is at least one of a seatbelt sensor, motion sensor, optical camera, seat belt sensor, ignition sensor, vehicle motion sensor, gear sensor, and door handle sensor;

wherein the determination of the exit condition by the processor is based on the first signal.

3. The system of claim 1, wherein the warning signal system further comprises a second sensor configured to detect a second signal capturing an environment around the vehicle, wherein the second sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor;

and, wherein the determination of the traffic condition by the processor is based on the second signal.

4. The system of claim 1, wherein the warning signal is a visual warning signal.

5. The system of claim 1, wherein the warning signal is a light beam.

6. The system of claim 1, wherein the warning device is a display.

7. The system of claim 1, wherein the warning signal is an auditory warning signal.

8. The system of claim 1, wherein the warning device is an audio speaker.

9. The system of claim 1, wherein the warning device is configured to provide a vibratory warning signal.

10. A method for warning a vehicle occupant of a hazard condition, the method being implemented by a vehicle collision warning system comprising:

a processor,

a warning signal system configured to emit a warning signal to warn a vehicle occupant about the hazard condition, the warning signal system comprising;

a warning device configured to emit the warning signal, wherein the method comprises;

determining an exit condition indicating that the vehicle occupant is about to exit the vehicle from a side of the vehicle, wherein determining the exit condition comprises receiving a signal from an exit sensor;

determining a traffic condition indicating a traffic around the vehicle;

detecting a hazard condition is on the same side of the vehicle where the occupant is about to exit the vehicle based on the exit condition and the traffic condition; and

in response to the hazard condition having been detected, generating a control signal for transmission to the warning device to emit the warning signal; and

, wherein

the warning device is further configured to receive the control signal and emit a warning signal to warn the vehicle occupant about the hazard condition.

11. The method of claim 10, wherein the exit sensor is at least one of a seatbelt sensor, motion sensor, optical camera, seat belt sensor, ignition sensor, vehicle motion sensor, gear sensor, and door handle sensor;

wherein the determination of the exit condition by the processor is based on the first signal.

12. The method of claim 11, wherein the warning signal system further comprises a second sensor configured to detect a second signal capturing an environment around the vehicle, wherein the second sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor;

and, wherein the determination of the traffic condition by the processor is based on the second signal.

13. The method of claim 11, wherein the warning signal is a visual warning signal.

14. The method of claim 11, wherein the warning signal is a light beam.

15. The method of claim 11, wherein the warning device is a display.

16. The method of claim 11, wherein the warning signal is an auditory warning signal.

17. The method of claim 11, wherein the warning device is an audio speaker.

18. The method of claim 11, wherein the warning device is configured to provide a vibratory warning signal.
