11.￿Road￿Sign￿Recognition
The￿Speed￿Limit￿Information￿optional￿equipment￿has￿been￿expanded￿to￿include￿the￿display￿of￿most
legal￿signs￿(￿i.e.￿normal￿speed￿limit￿signs,￿school￿signs,￿construction￿signs)￿and￿will￿be￿referred￿to￿as
road￿sign￿recognition￿from￿now￿on￿in￿this￿document.￿Current￿top￿speed￿limitations￿and￿no￿overtaking
signs￿are￿detected￿by￿the￿road￿sign￿recognition￿system￿and￿displayed￿in￿the￿instrument￿cluster￿or￿the
Head‐Up￿Display￿in￿the￿form￿of￿road￿sign￿symbols.

The￿display￿of￿road￿signs￿is￿based￿on￿the￿evaluation￿of￿data￿from￿the￿navigation￿system￿and￿the
evaluation￿of￿image￿data￿recorded￿by￿the￿KAFAS￿stereo￿camera.
The￿KAFAS￿stereo￿camera￿detects￿road￿signs￿at￿the￿edge￿of￿the￿road￿and￿also￿the￿variable￿displays￿of
gantry￿signs.￿Road￿signs￿containing￿additional￿information,￿e.g.￿"In￿wet￿conditions",￿are￿also￿detected
and￿synchronised￿with￿vehicle-internal￿data,￿e.g.￿the￿rain￿sensor,￿and￿displayed￿depending￿on￿the
situation.
The￿system￿also￿takes￿the￿applicable￿time￿restrictions￿identified￿into￿account,￿e.g.￿"between￿10.00
pm￿and￿6.00￿am".￿The￿current￿time￿of￿the￿on-board￿clock￿is￿used￿for￿this.￿The￿system￿takes￿the
information￿stored￿in￿the￿navigation￿system￿into￿account￿and￿displays￿existing￿top￿speed￿limitations
on￿sections￿of￿road￿without￿signage.
Road￿sign￿recognition￿(Speed￿Limit￿Information)￿is￿part￿of￿the￿Active￿Driving￿Assistant￿optional
equipment￿(OE￿5AS)￿in￿the￿G12.
The￿system￿does￿not￿relieve￿the￿driver￿of￿personal￿responsibility￿for￿correctly￿judging￿the￿visibility￿and
traffic￿situation.￿The￿driver￿is￿solely￿responsible￿for￿the￿vehicle￿and￿the￿speed￿at￿which￿it￿is￿driven.
