3.￿KAFAS
3.5.￿Detection￿of￿the￿road￿condition
The￿KAFAS￿stereo￿camera￿in￿the￿G12￿also￿detects￿the￿road￿condition.
In￿vehicles￿with￿the￿Executive￿Drive￿Pro￿optional￿equipment￿(OE￿2VS),the￿data￿collected￿is￿used
to￿adapt￿the￿chassis￿and￿suspension￿setting￿to￿the￿road￿condition￿by￿changing￿various￿setting
parameters￿in￿the￿Dynamic￿Drive￿(ARS)￿and￿Electronic￿Damper￿Control￿(EDC)￿and￿tailoring￿the
interaction￿with￿the￿two-axle￿air￿suspension.
Detection￿of￿road￿bumps￿with￿the￿help￿of￿the￿stereo￿camera
Objects￿can￿now￿be￿dealt￿with￿actively￿instead￿of￿reactively,￿and￿therefore￿more￿easily,￿at￿speeds￿of
approximately￿15￿to￿100￿km/h.
The￿structure￿of￿the￿vehicle￿moves￿less￿vertically,￿as￿the￿vehicle￿drives￿in￿harmony￿with￿the￿road.
Bumps￿are￿less￿noticeable￿for￿the￿driver.
3.6.￿Functional￿limitations
The￿function￿of￿the￿KAFAS￿stereo￿camera￿and￿thus￿the￿function￿of￿the￿corresponding￿assistance
systems￿may￿be￿impaired￿due￿to￿the￿physical￿limits￿of￿the￿optical￿systems,￿for￿example￿in￿the
following￿situations:
• Heavy￿fog,￿rain,￿spray￿or￿snow
• Strong￿light￿in￿the￿camera￿lens
• If￿the￿field￿of￿view￿of￿the￿KAFAS￿stereo￿camera￿or￿the￿windscreen￿is￿dirty
• On￿tight￿bends
• If￿boundary￿lines￿are￿missing,￿worn,￿poorly￿visible,￿converging￿or￿diverging,￿or￿not
clearly￿recognizable,￿as￿may￿be￿the￿case￿when￿roadworks￿are￿being￿carried￿out
• If￿boundary￿lines￿are￿covered￿by￿snow,￿ice,￿dirt￿or￿water
• If￿boundary￿lines￿are￿covered￿by￿objects
