ABSTRACT:
A real-time (instantaneous) vehicle anti-theft warning, notification and tracking system is disclosed that eliminates false alarms by comparing a calculated displacement profile representing the characteristics of a measured displacement (or apparent displacement) of a vehicle with predetermined displacement profiles. The present invention employs a displacement sensor with a unique monitoring program that measures the rate-of-change, direction, and/or duration of displacement of a vehicle (e.g., an automobile or aircraft) over time, and accurately characterizes real and virtual displacements based on the comparison of the calculated displacement profile with the predetermined displacement profiles. The invention also may include GPS/cellular indication capability to alert the vehicle owner of a theft event, and may also include a discrimination indicator to alert the vehicle owner that GPS/cellular capability is not available.
