11.￿Road￿Sign￿Recognition
11.1.￿Operation
The￿road￿sign￿recognition￿can￿be￿switched￿on￿and￿off￿in￿the￿iDrive￿menu.￿by￿making￿the￿following
selection￿via￿the￿controller:
• "My￿Vehicle"
• "System￿settings"
• "Displays"
• "Instrument￿Cluster"
• Apply￿desired￿settings.
11.2.￿Limits￿of￿the￿system
Road￿signs￿for￿top￿speed￿limitations￿that￿do￿not￿comply￿with￿the￿legal￿standard,￿particularly￿those
without￿circular￿frames,￿are￿not￿always￿detected.￿The￿same￿also￿applies￿for￿traffic￿signs￿which￿are￿fully
or￿partially￿covered￿by￿labels,￿dirt￿or￿vegetation.￿Long￿distances￿to￿the￿road￿sign,￿high￿driving￿speeds
and￿poor￿weather￿conditions,￿particularly￿at￿night,￿make￿it￿more￿difficult￿for￿the￿system￿to￿recognize
road￿signs￿reliably.￿To￿ensure￿the￿current￿top￿speed￿limitations￿are￿displayed￿as￿accurately￿as￿possible,
the￿data￿of￿the￿navigation￿road￿map￿should￿be￿up-to-date.
The￿functionality￿of￿the￿road￿sign￿recognition￿may￿be￿impaired￿in￿the￿following￿situations￿and￿may￿lead
to￿incorrect￿information￿being￿displayed:
• heavy￿fog,￿rain￿or￿snow
• if￿signs￿are￿covered￿by￿objects
• If￿driving￿at￿close￿proximity￿to￿a￿vehicle￿driving￿ahead
• Strong￿light￿in￿the￿camera￿lens
• if￿the￿windscreen￿in￿front￿of￿the￿interior￿mirror￿is￿misted￿over,￿soiled￿or￿covered￿by￿stickers,￿etc.
• as￿a￿result￿of￿incorrect￿detection￿by￿the￿camera
• if￿the￿top￿speed￿limitations￿stored￿in￿the￿navigation￿system￿are￿incorrect
• in￿areas￿not￿covered￿by￿the￿navigation￿system
• in￿the￿event￿of￿deviations￿from￿the￿navigation,￿e.g.￿due￿to￿modified￿road￿layouts
• when￿overtaking￿buses￿or￿trucks￿with￿speed￿limit￿stickers
• if￿road￿signs￿do￿not￿correspond￿to￿the￿standard
• when￿calibrating￿the￿camera￿immediately￿after￿vehicle￿delivery.
Supplementary￿sign￿recognition
Only￿additional￿characters￿with￿symbols￿(icons)￿can￿be￿recognized￿by￿the￿system,￿such￿as￿"in￿wet
weather",￿"in￿rain/snow",￿"truck"￿or￿"trailer",￿etc.￿Text￿notes￿on￿additional￿characters￿can￿generally￿not
be￿read￿or￿interpreted.
