Abstract
A vehicle intrusion detection system (10) for detecting an intrusion condition of a vehicle (12) having an occupant compartment (14) partially defined by an outer structure (30) of the vehicle, comprises an actuatable illuminator (40) mounted in the vehicle and having a limited field of illumination (52) extending within the vehicle occupant compartment adjacent the vehicle outer structure. A linear imager (60) mounted in the vehicle (12) has a field of view (62) that substantially coincides with the field of illumination (52) of the illuminator (40). A controller (70) compares a first image taken by the imager (60) when the illuminator (40) is actuated and a second image taken by the imager when the illuminator is unactuated to help determine the existence of an intrusion condition of the vehicle.
