22.1.8.￿Deactivation￿criteria
The￿steering￿and￿lane￿control￿assistant￿including￿traffic￿jam￿assistant￿is￿deactivated￿automatically￿in
the￿following￿situations:
• If￿the￿vehicle￿departs￿from￿the￿detected￿lane￿or￿the￿lane￿width￿does￿not￿meet￿the
requirements.
• If￿the￿lane￿edges￿of￿the￿current￿lane￿are￿not￿detected￿by￿the￿KAFAS￿stereo￿camera.
• If￿no￿vehicle￿driving￿ahead￿is￿detected.
• The￿vehicle￿is￿travelling￿at￿a￿speed￿greater￿than￿210 km/h.
• If￿the￿Hands-off-Detection￿cannot￿detect￿the￿hands￿(at￿least￿one￿hand)￿on￿the￿steering￿wheel
rim.￿Switch-off￿occurs￿once￿a￿defined￿time￿threshold￿(several￿seconds)￿has￿elapsed.
• Due￿to￿the￿radius￿of￿the￿bend￿in￿the￿road,￿the￿inner￿lane￿edge￿is￿no￿longer￿detected￿due￿to￿the
camera￿aperture￿angle.
• Pedestrian￿protection￿assumes￿the￿operating￿condition￿"Fault￿exists".
• If￿the￿turn￿indicator￿is￿on.
• The￿driver￿intervenes￿actively￿in￿the￿steering.
• If￿over￿a￿certain￿time￿period￿no￿lane￿edges￿are￿detected￿and￿there￿is￿not￿a￿vehicle￿driving
ahead.
• If￿the￿driver￿manually￿deactivates￿the￿DSC￿(DSC￿off).
• If￿there￿is￿an￿intervention￿from￿the￿preventative￿pedestrian￿protection.
• After￿Dynamic￿Brake￿Control￿braking￿(brake￿assistant).
22.1.9.￿Limits￿of￿the￿system
When￿driving￿in￿narrow￿lanes,￿e.g.￿when￿driving￿through￿roadworks￿or￿when￿emergency￿lanes￿are
formed,￿the￿system￿cannot￿be￿activated￿or￿used￿meaningfully.
Due￿to￿the￿limited￿detection￿capacity￿of￿the￿KAFAS￿stereo￿camera,￿the￿driver￿must￿remain￿alert￿and
observant￿in￿order￿to￿be￿able￿to￿actively￿intervene￿at￿any￿time￿so￿as￿to￿avoid￿the￿risk￿of￿an￿accident.￿The
system￿does￿not￿relieve￿the￿driver￿of￿personal￿responsibility￿for￿correctly￿judging￿the￿traffic￿situation.
The￿driver￿is￿solely￿responsible￿for￿the￿vehicle.
