G12￿Driver￿Assistance￿Systems
9.￿Blind￿Spot￿Detection
The￿Blind￿spot￿detection￿system￿can￿detect￿traffic￿situations￿that￿could￿pose￿a￿risk￿if￿the￿driver
changes￿lane.￿These￿traffic￿situations￿include￿vehicles￿approaching￿quickly￿from￿behind￿or￿vehicles
in￿the￿driver's￿blind￿spot.
The￿driver￿may￿find￿it￿difficult￿to￿judge￿these￿situations,￿especially￿when￿it￿is￿dark.￿The￿radar￿sensors
detect￿vehicles￿in￿the￿blind￿spot￿and￿work￿effectively￿regardless￿of￿the￿lighting￿conditions.￿In￿addition,
they￿are￿able￿to￿reliably￿detect￿such￿situations￿up￿to￿a￿distance￿of￿approximately￿70￿m￿away￿and
irrespective￿of￿the￿weather￿conditions.
G12￿vehicle￿detection￿using￿radar￿sensors￿(Blind￿spot￿detection)
When￿a￿vehicle￿is￿approaching￿quickly￿or￿moves￿into￿the￿blind￿spot￿of￿the￿driver's￿vehicle,￿the￿system
assists￿the￿driver￿by￿correctly￿judging￿the￿situation.￿If￿the￿lane￿next￿to￿the￿driver's￿vehicle￿is￿occupied,
the￿radar￿sensors￿detect￿the￿vehicles￿in￿the￿neighboring￿lane.
The￿control￿units￿(radar￿sensors)￿for￿the￿Blind￿spot￿detection￿(SWW)￿are￿located￿under￿the￿rear
bumper.
G12￿Blind￿spot￿detection￿(SWW)￿(radar￿sensors)
The￿control￿unit￿for￿the￿Blind￿spot￿detection￿(SWW)￿(primary)￿is￿installed￿on￿the￿right￿and￿the￿control
unit￿for￿the￿Blind￿spot￿detection￿(SWW2)￿(secondary)￿is￿installed￿on￿the￿left.
When￿a￿vehicle￿is￿detected￿and￿the￿system￿is￿activated,￿the￿driver￿is￿informed￿of￿the￿situation￿by￿an
unobtrusive￿indicator￿in￿the￿exterior￿mirror.￿By￿having￿this￿information￿before￿making￿a￿lane￿change
maneuver,￿the￿driver￿can￿confidently￿prepare￿for￿the￿lane￿change￿and￿avoid￿critical￿situations￿from
