Abstract

A communication system for a vehicle comprises a mechanism for sensing a change in speed of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle'"'"'s headlights based upon the change in speed. In particular, a headlight of the vehicle is able to be modulated as the vehicle reduces speed and/or is decelerating as it approaches an intersection. Additionally, the headlight of the vehicle is able to be modulated as the vehicle accelerates from a stopped position or reaches a certain traveling speed. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.

Claims

1. A communication system for a vehicle comprising:

a. a vehicle speed sensor for detecting a change in speed of the vehicle;

b. a control device; and

c. a headlight activation circuit for operating a headlight,

wherein the control device receives a signal from the vehicle speed sensor that the speed of the vehicle has changed and the control device sends a signal to the headlight activation circuit to change the headlight from a first light setting to a second light setting, wherein the headlight is modulated at a rate based on one or more of the speed of the vehicle and a change of speed of the vehicle.

2. The communication system of claim 1 wherein the first light setting is an off position and the second light setting is an on position.

3. The communication system of claim 1 wherein the first light setting is low beam position and the second light setting is a high beam position.

4. The communication system of claim 1 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the vehicle reaches a defined speed.

5. The communication system of claim 4 wherein the headlight is modulated at a rate corresponding to the speed of the vehicle.

6. The communication system of claim 1 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the brake is applied and the vehicle slows to a defined speed.

7. The communication system of claim 1 wherein the communication system comprises a system activation detector which detects that the system has been activated and sends a signal to the control device.

8. The communication system of claim 1 wherein the communication system is installed as aftermarket-equipment.

9. The communication system of claim 1 wherein the vehicle comprises a motorcycle.

10. A communication system for a vehicle comprising:

a. an acceleration monitoring system for detecting a change in acceleration of the vehicle based on an absolute acceleration status of the vehicle;

b. a control device; and

c. a headlight activation circuit for activating a headlight,

wherein the control device receives a signal from the acceleration monitoring system based on an increase in acceleration or a decrease in acceleration and the control device sends a signal to the headlight activation circuit to change the headlight from a first light setting to a second light setting, wherein the headlight is modulated at a rate based on one or more of a speed of the vehicle and a change of speed of the vehicle.

11. The communication system of claim 10 wherein the first light setting is an off position and the second light setting is an on position.

12. The communication system of claim 10 wherein the first light setting is low beam position and the second light setting is a high beam position.

13. The communication system of claim 10 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the absolute acceleration status of the vehicle changes from zero to positive indicating that the vehicle is accelerating from a stopped position.

14. The communication system of claim 10 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the vehicle is decelerating.

15. The communication system of claim 14 wherein the headlight is modulated at a rate corresponding to the rate of deceleration of the vehicle.

16. The communication system of claim 10 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the brake is applied and the vehicle slows to a defined speed.

17. The communication system of claim 10 wherein the communication system comprises a system activation detector which detects that the system has been activated and sends a signal to the control device.

18. The communication system of claim 10 wherein the communication system is installed as aftermarket-equipment.

19. The communication system of claim 10 wherein the vehicle is a motorcycle.

20. A communication system for a vehicle comprising:

a. an accelerometer for detecting a change in acceleration of the vehicle based on an absolute acceleration status of the vehicle; and

b. a headlight activation circuit for activating a headlight,

wherein the control device receives a signal from the accelerometer based on an increase in acceleration or a decrease in acceleration and the control device sends a signal to the headlight activation circuit to change the headlight from a first light setting to a second light setting wherein the headlight is modulated at a rate based on one or more of a speed of the vehicle and a change of speed of the vehicle.

21. The communication system of claim 20 wherein the first light setting is an off position and the second light setting is an on position.

22. The communication system of claim 20 wherein the first light setting is low beam position and the second light setting is a high beam position.

23. The communication system of claim 20 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the absolute acceleration status of the vehicle changes from zero to positive indicating that the vehicle is accelerating from a stopped position.

24. The communication system of claim 20 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the vehicle is decelerating.

25. The communication system of claim 24 wherein the headlight is modulated at a rate corresponding to the rate of deceleration of the vehicle.

26. The communication system of claim 20 wherein the control device sends a signal to the headlight activation circuit to modulate the headlight when the brake is applied and the vehicle slows to a defined speed.

27. The communication system of claim 20 wherein the communication system comprises a system activation detector which detects that the system has been activated and sends a signal to the control device.

28. The communication system of claim 20 wherein the communication system is installed as aftermarket-equipment.
