Inside rearview mirror dimming, basic function

23.06.2020

Model

all (CAR)

with code 249 (Automatic dimming inside rearview mirror and outside mirrors)

General

The "Auto dimming inside rearview mirror" function protects the driver from being dazzled by following traffic.

Function requirements

No overvoltage or undervoltage

Circuit 15R ON

Reverse gear not engaged

Interior illumination not switched on

Function

For the function, two photo sensors installed in the mirror measure the brightness difference between the traffic area in front of and behind the vehicle. The inside rearview mirror evaluates the sensor signals and if the light intensity behind the vehicle is greater than in front of the vehicle, it dims the mirror glass.

For this purpose, the inside rearview mirror has a special electrochromatic layer on the glass. This contains electrolytes consisting of uniform crystals, similar to a LCD display. The inside rearview mirror applies a voltage to this layer, the crystals align themselves in a specific angle as a result. This leads to an immediate and depending on the light intensity and sensor measurement to a continuously variable darkening effect.

The inside rearview mirror also transmits the dimming request to the outside mirrors.
