Factors Affecting the Function
Due to unavoidable environmental factors
and conditions, the Traffic Sign Recognition
function may incorrectly identify or fail to
recognize trafc signs. In the following situations,
the functionality may be affected or not work:
● Poor visibility, such as snow, rain, or fog.
● Obstructions in front of the camera.
● High temperatures around the camera due to
direct sunlight.
● Glare caused by direct sunlight, oncoming
trafc, reections from wet roads, etc.
● Sudden changes in outdoor brightness, such
as when entering/exiting tunnels.
● Low light conditions at night or inside tunnels
without the front headlights on.
● Signs in complex areas, far from the vehicle,
in spots not illuminated by headlights, or at
road corners.
● Signs that are faded, bent, rotated at an
angle, damaged, covered with mud or snow,
obscured by trees, or blocked by other
objects or vehicles.
● Signs partially obscured by trees or other
objects.
● Reections of lights or shadows on the sign
surface.
● Signs that are too bright or too dark (electronic
signs).
● Small traffic signs, such as those in
combination signboards.
● Difficulty recognizing the graphics on the
sign.
● Potential misidentication of signs not in the
lane, especially when signs are placed near
the lane (e.g., at junctions between side
roads and main roads).
● Misidentication of objects similar in color or
shape to signs (similar signs, electronic signs,
billboards, buildings, etc.).
● Inability to recognize auxiliary signs that
provide additional information like weather,
time, vehicle type, etc.
The Traffic Sign Recognition function can
be turned on or off in the MP5 Assisted Driving
→ Smart Recognition interface.
