18.4.￿Functional￿principle
The￿Parking￿Maneuver￿Assistant￿function￿facilitates￿maneuvering￿into￿parking￿spaces￿that￿are￿parallel
(parallel￿parking)￿and￿perpendicular￿(bay￿parking)￿to￿the￿roadway.￿The￿system￿measures￿potential
parking￿spaces￿when￿driving￿past￿at￿a￿speed￿below￿approximately￿35 km/h￿without￿the￿system￿having
been￿activated.
The￿parking￿spaces￿are￿measured￿by￿two￿additional￿ultrasonic￿sensors,￿which￿are￿integrated￿into￿the
front￿wheel￿arch.￿These￿two￿sensors￿are￿connected￿to￿the￿Parking￿Maneuver￿Assistant￿(PMA)￿control
unit,￿which￿also￿incorporates￿the￿Park￿Distance￿Control￿function.￿The￿function￿of￿the￿two￿ultrasonic
sensors￿is￿similar￿to￿that￿of￿the￿Park￿Distance￿Control￿PDC.￿Ultrasonic￿pulses￿are￿sent￿and￿echo
impulses￿are￿received.
Two￿additional￿ultrasonic￿sensors￿are￿installed￿in￿the￿rear￿bumper￿of￿the￿G12￿to￿precisely￿detect￿the
size￿of￿a￿transverse￿parking￿space￿during￿the￿parking￿maneuver.￿The￿additional￿ultrasonic￿sensors
measure￿the￿distance￿to￿detected￿objects.
If￿a￿parking￿space￿of￿a￿sufficient￿length￿and￿width￿is￿found￿and￿the￿system￿is￿activated,￿the￿driver￿is
shown￿the￿space￿on￿the￿central￿information￿display.
The￿Parking￿Maneuver￿Assistant￿function￿then￿takes￿over￿the￿vehicle￿handling￿entirely,￿including
steering,￿braking￿and￿gear￿selection.
Spaces￿that￿do￿not￿have￿a￿vehicle￿at￿either￿side￿are￿also￿recognized￿as￿suitable￿parking￿spaces.￿This
makes￿it￿possible￿to￿park￿behind￿only￿one￿object.
The￿driver￿is￿still￿responsible￿for￿monitoring￿the￿vehicle￿environment￿and￿can￿intervene￿in￿the
automatic￿parking￿maneuver￿at￿any￿time￿if￿required￿due￿to￿the￿vehicle￿environment.￿When
searching￿for￿a￿parking￿space￿and￿when￿parking,￿all￿relevant￿information￿is￿presented￿to￿the￿driver
in￿an￿integrated￿display;￿from￿the￿parking￿space￿itself￿to￿the￿status￿of￿the￿parking￿assistant￿and
corresponding￿handling￿instructions￿through￿to￿distances￿from￿other￿objects.
