Abstract

A vehicle collision warning system including a vehicle that includes a first sensor configured to monitor for an exit condition, a second sensor configured to monitor for a hazard condition, an internal warning signal system configured to emit a warning signal to warn a vehicle occupant about the hazard condition, the internal warning signal system including at least one warning device configured to emit the warning signal, and a processor configured to detect an exit condition using a first signal from the first sensor, detect a hazard condition using a second signal from the second sensor, and control the at least one warning device in response to the hazard condition.

Claims

1. A vehicle collision warning system, comprising:

a gear 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 comprising;

a first warning device located on a first side of a vehicle and a second warning device located on a second side of the vehicle, wherein the first and second warning devices are independently controllable, and wherein the first warning device is configured to emit the warning signal when the hazard condition is proximate the first side of the vehicle and the second warning device is configured to emit the warning signal when the hazard condition is proximate the second side of the vehicle; and

a processor configured to;

receive the first signal from the optical camera to detect the exit condition;

receive the second signal from the second sensor to detect the traffic condition;

in response to the exit condition, determine whether one or more users of the vehicle are exiting the vehicle from the first side of the vehicle;

detect a location of the hazard condition based on the first and second signals;

determine whether the location of the hazard is on the first side of the vehicle;

in response to detecting the hazard condition being on first side of the vehicle, generate a control signal to cause the first to emit the warning signal to warn about the hazard condition; and

in response to detecting the hazard condition being on the second side of the vehicle, determine not to cause the first warning device to emit the warning signal to warn about the hazard condition.

2. The system of claim 1, wherein the processor is further configured to in response to detecting the hazard condition being on second side of the vehicle, generate a control signal to cause the second warning device to emit the warning signal to warn about the hazard condition.

3. 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.

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 first warning device and the second warning device are displays.

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

8. The system of claim 1, wherein the first warning device and the second warning device are audio speakers.

9. The system of claim 1, wherein the first warning device and the second warning device are configured to provide a vibratory warning signal.
