Automatic Glare-Resistant EC Mirror: Notes
An automatic glare-resistant EC (electro chromic) mirror has been adopted for the inside and outside rear view mirrors as standard equipment. This system uses 2 sensors that are attached onto the inside rear view mirror to detect the difference between the intensity of light entering the inside rear view mirror from the rear of the vehicle, and of the light surrounding the vehicle. See Fig 1-Fig 3 .
During nighttime driving, if a large difference in intensity exists between the surrounding light and the light entering the inside rear view mirror from the headlights of the vehicle driving behind, this system automatically reduces the reflection rate of the inside rear view mirror and thus dampens the glare on the mirror. The reflection rate of the outside rear view mirrors varies in accordance with the change in the reflection rate of the inside rear view mirror.
