19.3.�Active�cruise�control�with�Stop&Go�function
The�active�cruise�control�with�Stop&Go�function,�ACCStop&Go�(OE�5DF)�is�offered�as�optional
equipment�for�the�G12�as�part�of�the�ZDB�Driver�Assistance�Plus�II�(5AT)�package.
ACC�Stop&Go�adjusts�a�driver-specified�set�speed�and,�if�required�by�the�traffic�situation,�also
automatically�adjusts�the�preselected�following�distance�to�the�vehicle�driving�ahead�(detected
vehicles�include�passenger�cars,�trucks�and�motorbikes).�The�application�range�of�ACC�Stop&Go
ranges�from�higher�speeds�down�to�a�standstill.�The�distance�and�the�speed�are�automatically
adjusted�in�this�range.
G12�Active�Cruise�Control
Depending�on�the�stationary�time,�driving�off�from�a�standstill�is�performed�automatically�or�in
response�to�a�prompt�by�the�driver.�ACCStop&Go�not�only�detects�vehicles�that�are�slowly�coming
to�a�halt,�but�also�stationary�vehicles.
Due�to�improved�monitoring�in�front�of�the�vehicle,�the�system�is�capable�of�reacting�more�quickly
to�vehicles�swinging�in�and�out�and�turning�off.
The�extended�application�range�has�been�achieved�by�the�incorporation�of�the�KAFAS�stereo�camera.
Image�data�is�evaluated�by�the�ACCStop&Go�system.�The�KAFAS�control�unit�clearly�detects�vehicles
when�their�rear�ends�are�recorded�by�the�camera.�In�addition,�the�KAFAS�control�unit�ensures�that�the
driving�lane�information,�vehicle�positions�and�movements�are�determined.
In�addition�to�image�data,�radar�data�is�also�gathered�and�evaluated�by�the�radar�sensors.�This�fusion
of�image�and�radar�data�makes�possible�the�clear�identification�of�lane�markings�and�the�distinction
between�stationary�vehicles�and�other�fixed�objects.
