Abstract
A warning display system visually warns the driver of a vehicle of an object in a detection zone, such as a blind spot region of the vehicle. The display system includes an imaging medium for displaying a warning indicator and a light source disposed behind the imaging medium for providing a controlled illumination of the warning indicator. An object detection sensor detects an object in a vehicle detection zone. One or more signals are processed to determine an anticipated movement of the vehicle in relation to the object. The system further includes a controller for adaptively controlling illumination of the light source to increase illumination of the warning indicator when the vehicle is anticipated to be moving towards the object.
