Abstract

A warning system for vehicles includes a controller and a light arrangement mounted to a vehicle. The controller includes a g force sensor configured to measure a g force value being exerted on the vehicle. The light arrangement is operationally coupled to the controller and is configured to flash at different flash rates based on the measured g force values sensed by the controller. The controller can be operationally coupled to a brake light sensor and can be numerically leveled upon activation of the brake light sensor.

Claims

1. A vehicle warning system comprising:

a controller mounted to a vehicle, the controller including a g force sensor configured to measure a g force value being exerted on the vehicle, the controller configured to compare the measured g force value to at least a first threshold value and a second threshold value; and

a light arrangement, the light arrangement operationally coupled to the controller, the light arrangement configured to flash at a first flash rate if the controller determines that the measured g force value is greater than or equal to the first threshold value and less than the second threshold value and to flash at a second flash rate if the controller determines that the measured g force value equals or exceeds the second threshold value.

2. The system of claim 1, wherein the light arrangement includes at least one light bar.

3. The system of claim 1, wherein the light arrangement includes at least a first light bar having at least one lamp pair.

4. The system of claim 3, wherein the light arrangement includes two light bars.

5. The system of claim 3, wherein each light arrangement includes at least a first and second lamp pair.

6. The system of claim 5, wherein the first lamp pair is configured to flash at the first flash rate and the second lamp pair is configured to flash at the second flash rate.

7. The system of claim 1, wherein the controller is portable.

8. The system of claim 1, wherein the light arrangement is configured to flash at a third flash rate if the measured g force value equals or exceeds a third threshold value.

9. The system of claim 1, wherein the controller is electrically coupled to a brake light system of the vehicle and is further configured to level the g force sensor when the brake light system activates.

10. The system of claim 1, wherein the controller is mounted in the front of the vehicle and the light arrangement is mounted to a rear of the vehicle.

11. The system of claim 1, wherein the controller is operationally coupled to an existing safety or operational system of the vehicle and wherein the light arrangement illuminates when the existing safety or operational system activates.

12. A method for warning trailing vehicles of deceleration of a leading vehicle, the method comprising:

sensing activation of a vehicle brake light system of the leading vehicle;

obtaining a first g force value of the leading vehicle when the activation is sensed;

obtaining a second g force value of the leading vehicle;

comparing the second g force value to the first g force value to obtain a difference; and

illuminating at least a portion of a light arrangement viewable to at least one trailing vehicle if the difference between the second g force value and the first g force value exceeds a first threshold value.

13. The method of claim 12, further comprising flashing the illuminated portion of the light arrangement at a flash rate.

14. The method of claim 12, further comprising:

illuminating a first lamp pair of the light arrangement when the difference equals or exceeds the first threshold value; and

illuminating the first lamp pair and a second lamp pair of the light arrangement when the difference equals or exceeds a second threshold value.

15. The method of claim 14, further comprising:

flashing the first lamp pair at a first flash rate when the difference equals or exceeds the first threshold value; and

flashing the first and second lamp pair at a second flash rate when the difference equals or exceeds the second threshold value.

16. The method of claim 14, further comprising:

illuminating the first lamp pair, the second lamp pair, and a third lamp pair of the light arrangement at a third flash rate when the difference equals or exceeds a third threshold value.
