8.￿Cruise￿Control
8.1.￿Introduction
Two￿cruise￿controls￿are￿offered￿for￿the￿F48.￿The￿customer￿can￿choose￿between￿the￿optional
equipment￿DCC￿cruise￿control￿with￿braking￿function￿and￿the￿optional￿equipment￿ACC￿active￿cruise
control.
The￿DCC￿is￿an￿element￿of￿the￿optional￿equipment￿Driving￿Assistant￿Plus￿(SA￿5AT),￿or￿can￿be￿ordered
as￿separate￿optional￿equipment￿(SA￿544).
The￿ACC￿Stop￿&￿Go￿function￿was￿extended￿with￿the￿traffic￿jam￿assistant￿function.￿The￿traffic￿jam
assistant￿is￿described￿in￿more￿detail￿in￿chapter￿9￿"Traffic￿jam￿assistant".
The￿speed￿control￿systems￿support￿the￿driver￿with￿adapting￿his￿speed,￿distance￿and￿driving￿style
to￿the￿traffic￿conditions￿but￿do￿not￿relieve￿him￿of￿this￿responsibility.￿The￿driver￿may￿need￿to￿actively
intervene,￿e.g.￿by￿braking,￿steering￿or￿taking￿evasive￿action,￿as￿otherwise￿there￿is￿a￿risk￿of￿an￿accident.
8.2.￿Cruise￿control￿with￿braking￿function
The￿cruise￿control￿with￿braking￿function￿(SA￿544)￿is￿used￿in￿the￿F48￿as￿optional￿equipment.
The￿system￿is￿also￿referred￿to￿as￿"Dynamic￿Cruise￿Control".￿Dynamic￿Cruise￿Control￿supports￿the
driver￿on￿roads￿with￿less￿traffic￿by￿keeping￿the￿speed￿constant￿irrespective￿of￿the￿rolling￿resistances
(incline,￿vehicle￿load).￿In￿spite￿of￿the￿support,￿the￿driver￿remains￿responsible￿for￿control￿of￿the￿vehicle.
It￿is￿possible￿to￿override￿the￿DCC￿function￿at￿any￿time￿by￿braking￿or￿accelerating￿the￿vehicle.
When￿ECO￿PRO￿mode￿is￿activated,￿the￿cruise￿control￿is￿also￿adjusted￿to￿a￿consumption-friendly
driving￿style.
Depending￿on￿equipment,￿the￿calculation￿is￿effected￿in￿different￿control￿units:
• The￿calculations￿are￿performed￿by￿the￿DSC￿control￿unit.
• In￿vehicles￿that￿are￿equipped￿with￿an￿optional￿equipment￿system￿(SAS)￿due￿to￿other￿optional
equipment￿packages,￿the￿calculations￿are￿performed￿in￿the￿SAS￿control￿unit.
