The automatic dimming of the interior rear-view mirror is infinitely variable if the driver is dazzled from behind. The system consists of a mirror and electronics with two photo sensors.
Electronic mirror control unit 1 (pic. 12.70) receives information from photo sensors 2 and 3. If the backlight is greater than the front, the electronics unit supplies voltage to the electrically conductive coating 8, which is located between the protective glasses 4 and 6 of the mirror. Depending on the magnitude of the applied voltage, the transparency of the electrolyte layer 5 changes. The higher the voltage is applied, the darker the electrolyte layer. As a result, the intensity of light reflection from mirror 7 decreases.
