G12￿Driver￿Assistance￿Systems
22.￿Lane￿&￿Traffic￿Jam￿Assistant
The￿system￿has￿two￿sub-functions:￿the￿traffic￿jam￿assistant￿(second￿generation)￿and￿the￿lane￿control
assistant.
The￿traffic￿jam￿assistant￿can￿be￿used￿within￿the￿speed￿range￿of￿0￿to￿70￿km/h,￿the￿lane￿control￿assistant
on￿the￿other￿hand￿from￿70 to￿210￿km/h.
The￿table￿below￿shows￿an￿overview￿of￿the￿differences￿between￿the￿two￿sub-functions:
Traffic￿Jam￿Assist
Speed￿range￿0￿-￿70￿km/h
Corrective￿steering￿interventions￿in￿the
direction￿of￿the￿vehicle￿driving￿ahead
Detected￿lane￿markings￿taken￿into
consideration
If￿the￿traffic￿jam￿and￿lane￿control￿assistants￿are￿activated,￿the￿side￿collision￿warning￿is￿also￿interlinked.
22.1.1.￿Hands-off-Detection
To￿ensure￿the￿driver￿is￿alert￿and￿able￿to￿react,￿he￿is￿urged￿to￿always￿have￿both￿hands￿on￿the￿steering
wheel￿when￿the￿steering￿and￿lane￿control￿assistant￿including￿traffic￿jam￿assistant￿are￿activated
(established￿in￿the￿German￿road￿traffic￿regulations).￿If￿the￿driver￿takes￿both￿hands￿off￿the￿steering
wheel￿rim,￿control￿is￿stopped￿after￿a￿few￿seconds￿during￿active￿control￿and￿the￿driver￿is￿requested￿to
take￿over￿steering.
A￿capacitive￿sensor￿(hands-off￿detection￿sensor)￿with￿corresponding￿touch￿detection￿electronics￿in
the￿steering￿wheel￿determines￿whether￿the￿steering￿wheel￿is￿being￿touched.
The￿electronic￿touch￿detection￿is￿installed￿in￿the￿steering￿wheel￿below￿the￿driver's￿airbag.
