ABSTRACT:
An integrated system for automatic vehicle collision avoidance and warning for vehicles operating on any highway or road system globally. The system may be used to not only illuminate the brake lights on the following vehicle but also to begin the application of braking pressure as a result of analysis of the speed of the vehicle. The system includes an RFID transponder (either active or passive) located in the rear and front of the vehicle with discrete recognition capability as to vehicle proximity and resulting action to be taken as a result of driver action. On the vehicle either the brake lights will be illuminated ahead of any actual driver action; an initial application of brake pressure as a result of receiving a signal from the vehicle in front, the pressure which is determined by analysis of the current speed of the vehicle or the system will provide additional warning through brake light illumination to the following vehicle with similar equipment and cruise control will be disengaged. The system can be retrofitted into existing vehicles to provide, at a minimum, brake light illumination indicating an action being taken somewhere ahead of your vehicle. The system thereby warns and prevents serious rear-end collisions at highway speeds especially where vehicle size mismatch contributes to the inability of the following driver to see activity in front of the car in front of him.
