Automatic anti-dazzle interior mirror
Automatic anti-dazzle interior mirror
The automatic anti-dazzle interior mirror darkens continuously when the driver is blinded from behind.
It consists of a mirror element and electronics with two photo sensors.
The photo sensors of the electronics detect the light incidence from the front and the rear.
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 colour of the electrolyte. The greater the voltage, the darker the electrolyte. Therefore, the incident light is reflected to a lesser degree.
Selecting reverse gear switches off the anti-dazzle function. Consequently, one can, for example, reverse out of a dark garage with the aid of the interior mirror.
