Brake light warning system with early warning feature
First Claim
1. A brake light warning system for a motor vehicle comprising:
- one or more proximity sensors configured to emit one or more signals to detect a proximity of one or more nearby vehicles, the one or more proximity sensors located at a rear end of the motor vehicle;
a speed sensor configured to determine a speed of the motor vehicle;
a warning area behind the motor vehicle having a size within a range of the one or more signals;
a warning device comprising one or more brake lights of the motor vehicle, the warning device configured to provide a visual warning to an operator of the one or more nearby vehicles;
a user alert device configured to provide an alert to an operator of the motor vehicle; and
a controller in communication with the one or more proximity sensors and the speed sensor, whereby the controller is configured to activate the user alert device and the one or more brake lights when the proximity of the one or more nearby vehicles is within the warning area, the controller configured to set the size of the warning area based on the speed of the motor vehicle.

Abstract
A brake light warning system provides a warning to nearby motorists whose vehicles are within a warning area adjacent a user vehicle. The warning system may provide a visual warning to these motorists by illuminating one or more brake lights of the user vehicle. A user alert device may also be activated to alert the user to a nearby vehicle that is within the warning area. The warning area may be fixed or may bet set based on the speed of the user vehicle to warn nearby motorists that they are too close to the user vehicle. The warning system may provide a warning via a brake light without activating the braking system of the user vehicle. The warning system may utilize components of the user vehicle to detect vehicle speed, nearby vehicles, provide warnings, provide alerts, or a combination thereof.

9. A vehicle proximity warning system for a user vehicle for alerting an operator of a secondary vehicle of their proximity to the user vehicle comprising:
-
one or more sensors associated with the user vehicle, the one or more sensors configured to provide an output indicative of the secondary vehicle proximate a rear end of the user vehicle; at least one warning device associated with the user vehicle, the at least one warning device configured to emit a warning to the operator of the secondary vehicle; a controller configured to receive said the output from the one or more sensors and to activate the at least one warning device when the secondary vehicle is proximate the rear end of the user vehicle. - View Dependent Claims (10, 11, 12, 13, 14, 20)

15. A method of providing a warning to an operator of a secondary vehicle of their proximity to a user vehicle comprising:
-
detecting a presence of the secondary vehicle in proximity to a rear end of the user vehicle utilizing one or more sensors associated with the user vehicle while the user vehicle is travelling forward; determining if the nearby vehicle is within a warning area of the user vehicle; and when the proximity of the secondary vehicle is within the warning area, activating one or more warning devices associated with the user vehicle to cause the one or more warning devices to emit a warning signal to the operator of the secondary vehicle of the proximity of the secondary vehicle to the user vehicle. - View Dependent Claims (16, 17, 18, 19)
