1. A system for detecting objects in a predicted path of a vehicle moving on a highway lane, comprising:

  • a forward looking sensor for providing range, angle and velocity data for objects within a field of view in front of said vehicle;

    measuring systems for providing velocity and yaw rate data for said vehicle; and

    a processing system responsive to said forward looking sensor and said measuring systems to calculate an estimated path of said vehicle based on its velocity and yaw rate while said vehicle traverses the highway lane, and to calculate estimated paths for each of said objects sensed within the field of view in front of said vehicle, and to determine a lateral distance of each object sensed within the field of view in front of said vehicle from the predicted path of said vehicle while said vehicle traverses the highway lane, and classifying each object sensed within the field of view in front of said vehicle as either in or out of the highway lane of said vehicles, wherein the predicted path of said vehicle is generated by correlating the estimated path of said vehicle and said objects and fusing the paths of said objects as a weighted average.
