Wiper Control System
When "AUTO" switch signal is received from the multi-function switch
on the right, the integrated rain sensor detects the amount of rainfall.
The sensor is installed inside the upper part of the front window
for wiper motor control.
This system automatically controls the operation duration and speed
of the wiper depending on the measured amount of rainfall even if
the driver does not operate the wiper switch.

Functions and Operating Principles |
1. |
Detecting the amount of rainfall
The light (beam) emitted from light emitting diodes (LED) is totally
reflected on the external surface of the windshield and comes back
to the photo diodes. When there is water on the external surface
of the windshield, the light is optically separated and reflected
partially and the remaining brightness is measured by the photo
diodes. Water remaining on the windshield results in the light being
not totally reflected. The loss of brightness due to this indicates
how much the glass surface is wet.

Dust on the measuring surface and other surfaces on the light path
(surface of light emitting diodes and photo diodes, fiber optics,
bracket, and glass surface of windshield joint area) weakens the
received light.

Movement of windshield and bracket

3. |
Movement of bracket due to vibration
