The display area is divided in three
different sectors:
1 Conditioned speed limit area.
2 Unconditioned speed limit area.
3 Overtaking restriction area.
NOTE:
Overtaking restriction sign will be
displayed only in markets where this is
allowed.
If “Blinking On” warning mode is set,
when the visual warning is provided
only the unconditioned speed limit (in
sector 2 ) will start blinking when the
vehicle speed exceeds to the detected
unconditioned speed limit (“+0 mph”
or “+0 km/h” option) or when it
exceeds the set sensitivity value
(“+5 mph” - “+5 km/h” or “+10 mph” -
“+10 km/h” options). If the vehicle
speed stays above the unconditioned speed limit for several seconds the
unconditioned speed limit sign will
stop blinking because the manoeuvre
is evaluated as intentional. If the TSA
is not able to determine any kind of
valid speed limit neither from camera
nor from digital maps the following
image will be shown in sector 2 .
Since TSA also uses the data provided
by the navigation system, it can
update the sector 2 of the display in
the following situations without
detecting traffic signs:
• When the vehicle changes road.
• Highway enter/exit.
• Urban area stored in the digital map
enter/exit.
System Limitations TSA may be impaired or may not
function in the following situations:
• If there is poor visibility, e.g. due to
insufficient illumination of the road,
if there are highly variable shade
conditions or in rain, snow or fog.
• If there is glare, e.g. from oncoming
traffic, direct sunlight or reflections
from other vehicles.
• If the windshield in the area of the
camera is dirty, or if the camera is
fogged up, damaged or covered. • If the traffic signs are hard to detect,
e.g. due to dirt or snow, or because
they are covered or because of
insufficient lighting.
• If the information in the navigation
system's digital map is incorrect or
out-of-date.
• If the signs are ambiguous, e.g.
traffic signs on construction sites or
in adjacent lanes.
• When passing buses or trucks with a
speed sticker.Driving
