COLLISION-AVOIDANCE SYSTEM AND METHOD

摘要

A method and apparatus for avoiding collisions of moving vehicles uses a position and motion locating system to track vehicle location and motion within a preconfigured operational zone. Each of a plurality of operational vehicles has a positioning device that communicates with a server to track the location and movement of each vehicle. The collision-avoidance system receives information on the position of each vehicle and determines a predicted trajectory for each vehicle. Based upon the predicted trajectories, the system predicts potential collisions by determining areas of intersection of a vehicle with other vehicles or stationary objects. When a collision is predicted, instructions are transmitted to units within each vehicle within an area of intersection to provide a collision warning to the vehicle operator and/or to control the vehicle speed in order to prevent the predicted collision.

主权项

1. A system for avoiding collisions between operational vehicles within a defined operational environment, the system comprising:
a plurality of operational vehicles operating within the defined environment, each equipped with a vehicle-positional device; an array of tracking devices deployed throughout the defined environment to detect and report a position and a trajectory of each of the operational vehicles; a computer in electronic communication with the array of tracking devices; and a collision-avoidance algorithm operating on the computer, wherein the collision-avoidance algorithm identifies potential collisions based the positions and trajectories of each of the operational vehicles and reports potential collisions back to operational vehicles in danger of collision.
