Abstract

A collision warning system including a vehicle with a first sensor configured to detect an exit condition, a second sensor configured to detect a collision condition, an external warning signal system configured to emit a warning signal to warn a vehicle occupant about the collision condition, the external warning signal system includes at least one warning device configured to emit the warning signal, and a controller configured to communicate with the first and second sensors and to control the at least one warning device in response to the collision condition.

First claim

What is claimed is:

1 . A collision warning system, comprising:
a first sensor coupled to a vehicle and configured to generate a first signal indicating an exit condition; a second sensor coupled to the vehicle and configured to generate a second signal indicating neighboring traffic; and an external warning signal system coupled to the vehicle and configured to emit an audio and/or visual external warning signal in response to the first signal and the second signal to warn the neighboring traffic about a collision condition.

2 . The system of claim 1 , wherein the external warning signal system comprises a warning device coupled to the vehicle and configured to emit the audio and/or visual external warning signal.

3 . The system of claim 2 , wherein the external warning signal system comprises a controller configured to:
receive the first signal from the first sensor; receive the second signal from the second sensor; and generate a control signal to control the warning device to emit the audio and/or visual external warning signal to warn about the collision condition in response to receiving the first and second signals.

4 . The system of claim 2 , wherein the warning device is a display that displays at least one of a written message and a visual image that warns the neighboring traffic of the collision condition.

5 . The system of claim 2 , wherein the warning device is an audio speaker.

6 . The system of claim 1 , wherein the first sensor is at least one of a seatbelt sensor, motion sensor, optical camera, ignition sensor, gear sensor, and door handle sensor.

7 . The system of claim 1 , wherein the second sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor.

8 . The system of claim 1 , wherein the visual external warning signal is a light beam.

9 . A method for warning traffic of a collision condition around a vehicle, comprising:
receiving a first signal from a first sensor coupled to the vehicle, the first signal indicating an exit condition; receiving a second signal from a second sensor coupled to the vehicle, the second signal indicating neighboring traffic; and detecting a collision condition in response to the first and second signals.

10 . The method of claim 9 , comprising generating a control signal to cause a warning device coupled to the vehicle to emit an audio and/or visual external warning signal in response to the detected collision condition.

11 . The method of claim 9 , wherein the first sensor is at least one of a seatbelt sensor, motion sensor, optical camera, ignition sensor, gear sensor, and door handle sensor.

12 . The method of claim 9 , wherein the second sensor is at least one of an optical camera, infrared camera, motion detector, radar, laser, and ultrasonic sensor.

13 . The method of claim 9 , wherein the visual external warning signal is a light beam.

14 . The method of claim 13 , further comprising changing at least one of a color, an intensity, and a flash frequency of the light beam in response to a change in the collision condition.

15 . The method of claim 10 , wherein the warning device is a display.

16 . The method of claim 15 , further comprising displaying with the display at least one of a written message and a visual image as the visual external warning signal.

17 . The method of claim 10 , wherein the warning device is an audio speaker.

18 . The method of claim 9 , further comprising activating a visual external warning signal on a side of the vehicle where a passenger will exit.
