Abstract
An apparatus for sensing variations in an inductive field, or inductive sensor. The inductive sensor is adapted for detecting the lateral offset of a vehicle within a roadway, especially those with multiple traffic lanes, without regard to lane boundaries, which may vary. Lateral offset information is necessary for determining lane usage statistics and is useful in detecting unsafe driving behaviors evidenced by erratic variations in lane position. Such unsafe driving behaviors are indicative of, for example, intoxicated or drowsy drivers, obstacles in the roadway requiring drastic avoidance measures, aggressive driving and other generally unsafe roadway conditions. In addition, lane position information can be passed back to the vehicle to allow for automated lane-keeping or passed to other detectors for self-calibration of the system.
