Abstract

A plurality of sensors each gather information about a region around the periphery of a motor vehicle. The sensor system is equipped with a radar assembly, an infrared detection assembly, and a visible light detection assembly. A central processing unit integrates data gathered from the three assemblies and combines them to form an aggregate data set of the individual region. The CPU also combines aggregate data sets from all the sensors and displays the information on a dashboard mounted display. The display is an active matrix display that shows contacts relative to the motor vehicle, a level of threat imposed by each individual contact, and a blink rate for color blind applications. The display takes advantage of color active matrix technology, displaying low threats as green sprites, moderate threats as yellow or orange sprites, and severe threats as red sprites.
