Abstract
An object detection system includes a sensor in communication with a controller to identify an object within a field of view. Pattern recognition algorithms are incorporated into the controller, and particular objects are predefined to minimize false detection and sift predefined objects such as vehicles from background clutter. Upon recognition of the object, an indicator in communication with the controller provides an alert to the operator who can then take corrective action. By defining another field of view the controller halts or reverses the movement of a power window to prevent trapping an object between the closing window and the window frame. Yet another field of view includes a vehicle entry point such as a vehicle door. Movement of the vehicle door will be identified by the controller and will provide an alert such as activation of the vehicle alarm system.
