Mirrors: Description and Operation

Automatic Dimming Interior Mirror

The automatic dimming interior mirror darkens infinitely when the driver is "blinded" from behind.

It consists of a mirror element and an electric element with two photo sensors.

The electronic element recognizes the light incidence from front and back.

If the light incidence is greater from the rear than from the front the electronics apply voltage to the conductive coating.

The applied voltage changes the color of the electrolyte. The greater the voltage the darker the electrolyte. Therefore the light incidence is reflected to a lesser degree.

The dimming function is deactivated when reverse gear is selected. One can use the mirror to back out of a dark garage.
