Absolute acceleration sensor for use within moving vehicles
First Claim
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.

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.

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. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
