Rearview and Indirect-Vision Systems

There have been many improvements over the years in the mirror systems used on passenger vehicles and heavy trucks. Even so, the systems currently in use leave major blind zones that have been linked to elevated crash levels, primarily in lane-change and backing maneuvers. UMTRI researchers use their knowledge of crash data, driver visual perception, and vehicle geometries to determine how innovative mirrors (including convex and aspheric mirrors), camera systems, and object-detection systems can be combined to offer drivers more reliable and convenient ways to maintain awareness of the traffic environment around them.
