Patent ID: 7190260

Claim:
An anti-collision system for use within a motorized vehicle, comprising: means for sensing the urgency with which the brakes of a first vehicle are being activated and generating a first alert signal in response thereto; a visual indicator directed rearwardly of said first vehicle and configured to respond to said first signal; means for rearwardly communicating said first alert signal as a second alert signal, in the radio-frequency signal spectrum, said second signal configured to include vehicle position related data for qualifying said second alert signal upon receipt by anti-collision systems within vehicles following said first vehicle toward providing advance warning to drivers for the avoidance of collisions; wherein said position related data for qualifying said second alert signal comprises heading information and/or locating coordinates of said vehicle generating said second alert signal; wherein upon receipt said position related data may be compared with heading and/or locating coordinates by the anti-collision system within another vehicle and said alert signal ignored if generated from a sufficiently different heading or location; and wherein said means for rearwardly communicating is adapted for generating multiple levels of alert severity, including crash events associated with a collision along with levels of hard braking and swerving.
