RLS: Rain/Light Sensor

WARNING: This page is about a different car, the 2005 BMW 645Ci and 2004 BMW 645Ci. However, it is still accessible from the selected car via links, so may be relevant.

Vehicles with the "head-up display" special equipment (option 610) require a special rain/light sensor.

Modifications compared to the previous rain/light sensor:

Viewing Angle
On the previous rain/light sensor, the viewing angle has been directed more upwards (towards the sky). With the rain/light sensor for the head-up display, the viewing angle is directed more towards the virtual image (from the perspective of the rain/light sensor, downwards).

The rain-light sensor measures the ambient light conditions in the background of the virtual image. Thus the display brightness is optimally adjusted to the ambient brightness of the virtual image.
Optical Element
The optical element is adjusted to the new viewing angle.
Evaluation Electronics

The evaluation electronics have also been modified (signal evaluation and software).

As before, the signal is available via the K-CAN.
