19.￿Cruise￿Control
The￿system￿is￿interrupted￿automatically￿in￿the￿following￿situations:
• If￿the￿brakes￿are￿used
• If￿the￿selector￿lever￿position￿is￿moved￿out￿of￿position￿"D"
• If￿the￿Dynamic￿Traction￿Control￿(DTC)￿is￿activated￿or￿the￿Dynamic￿Stability￿Control
(DSC)￿is￿deactivated
• If￿the￿Dynamic￿Stability￿Control￿(DSC)￿is￿performing￿an￿adjustment
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.
