Inside rearview mirror with automatic dimmer
*
The interior rearview mirror with auto-
matic dimming feature reduces glare
from following traffic by adapting the in-
tensity of the reflected images to corre-
spond to levels of light registered by the
unit's sensors. The mirror reverts to its
undimmed setting as soon as the light
source disappears. One light sensor is
mounted on the front of the mirror
housing. This sensor, that is directed
forward, measures light intensity in the
area ahead of the vehicle. The second
sensor is integrated within the mirror's
glass. The electronic control system
compares the light intensity from front
and rear. The difference provides the
basic parameter used to modulate an
electrical current and induce chemical
changes in a semisolid layer incorpo-
rated in the lens.390de113
The semisolid reacts chemically to this
electrical current, thus providing infi-
nitely-variable dimming of the mirror
(electrochromic technology).
As a result, it is no longer necessary to
dim the mirror manually, and the driver
can maintain full concentration on traf-
fic.

Tire Pressure Control (RDC)
*
This system regularly checks tire pres-
sures and monitors all four tires even
while driving, so you don't have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that has a pressure sensor, a transmit-
ter and a battery. The pressure is mea-
sured in extremely short time intervals
and then transmitted by a radio signal.
If an irregularity is detected, the trans-
mission rate is increased. 462de257
Near every wheel there is an antenna in
the body that receives the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes. The RDC
plays an important part in driving safety.

Rain sensor
*
Depending on the degree of wetness
on the windshield, the rain sensor con-
trols the operation of the windshield
wipers.
Infrared light is carried along the sur-
face of the windshield in an optical con-
ductor in such a manner that it is
reflected completely when the wind-
shield is dry. The quantity of reflected
light is measured.
If there is moisture on the glass, the
amount of light reflected is reduced
since the infrared light at the surface of
the windshield can escape. The quan-
tity of reflected light is thus a means of
gauging the degree wetness on the
windshield.390de133
When the "Intermittent" wiper speed
position is selected, the wiper reacts
immediately if water is splashed onto
the windshield from vehicles traveling
ahead, for example. As a result, the rain
sensor provides a contribution to driv-
ing safety and comfort.
