Driver Evaluation Study of Rear View Mirror Reflectance Levels 710542

There has been a lack of information on image brightness in automotive rear vision systems as related to the driver's needs. This paper presents data on driver evaluation of brightness, in the form of visibility and glare ratings of rear view mirror reflectance levels, based upon actual driving experiences. The effects of roadway types and various ambient lighting conditions are discussed, and ranges of acceptable reflectance levels are recommended. The study was a task group effort, performed for the SAE Rear Vision Subcommittee.
