23.￿Active￿Lane￿Keeping￿Assistant
The￿active￿lane￿keeping￿assistant￿with￿active￿side￿collision￿protection￿is￿part￿of￿the￿Active￿Driving
Assistant￿Plus￿optional￿equipment￿(OE￿5AT).
The￿system￿assists￿the￿driver￿in￿keeping￿the￿vehicle￿in￿lane￿and￿actively￿avoiding￿potential￿side
collisions￿by￿initiating￿corrective￿steering￿interventions￿within￿a￿speed￿range￿from￿70￿km/h￿to￿210￿km/
h.￿The￿system￿endeavours￿to￿orient￿the￿vehicle￿in￿its￿lane￿according￿to￿the￿situation￿and￿within￿the
framework￿of￿the￿system￿limits.
The￿system￿consists￿of￿the￿following￿four￿sub-functions:
• Side￿collision￿warning
• Lane￿departure￿warning
• Blind￿Spot￿Detection

23.1.1.￿Reduced￿side￿collision￿warning
The￿reduced￿side￿collision￿warning￿comes￿into￿play￿if￿it￿is￿not￿possible￿to￿adequately￿monitor￿the
