If there is a risk of collision with a stationary obstacle
when turning right, the red warning lamp in the
A-pillar flashes and a warning tone sounds and the
appropriate SGA warning telltale appears on the
driver display screen. The red warning lamp stops
flashing after a few seconds but stays on as long as
there is a risk of a collision.
Detroit Assurance Traffic Sign
Display
General Information
NOTE: Traffic sign display requires Intelligent
Powertrain Management (IPM) to function.
If equipped, the Detroit Assurance Traffic Sign
Display system may increase road safety by making
the driver aware of posted traffic signs. Traffic sign
display uses video data from the multipurpose
camera in combination with GPS map data to
recognize USA and Canadian traffic signs and
display them on the ICUC ’Driver Assistance’ screen.
GPS information dictates the language and style of
the sign display.
Safety Information
Traffic sign recognition and display is only intended
as an aid for a conscientious and alert driver. The
system may not operate as designed under the
following conditions:
•
There is low visibility caused by insufficient
road illumination or because of snow, rain, fog,
smoke, or heavy spray.
•
There is glare or reflections from oncoming
traffic, the sun, or a wet road surface.
•
There are variable shade conditions on the
road surface.
•
The windshield is dirty, misted up, damaged, or
covered in the vicinity of the camera.
•
The traffic signs are partly or fully hidden by
other vehicles, bushes, or trees.
•
The distance from the vehicle in front is too
small and it prevents the traffic signs from
being detected in time.
•
The traffic signs are designed in a non-
standardized form, with additional text, or are
LED panels.
•
The traffic signs are damaged, bent, twisted,
stained, or scratched.
•
The traffic signs are posted on the far side of
the road or very high above the road and out
of view of the camera.
•
The road is very wide, winding, or has sharp
turns.
•
GPS satellite reception is limited due to
geographical location or development along the
road.
•
The onboard map data is outdated due to
recent changes in local traffic regulations or
new road layout.
The traffic sign recognition system not take the road
and weather conditions into account, nor the current
traffic situation. The driver is responsible for the
distance to the vehicle in front, for vehicle speed,
braking in good time, and remaining in the lane.
Traffic Sign Display Functionality
NOTE: Only three types of USA and Canadian
traffic signs are currently detectable:
•
speed limit signs (from speeds 5 to 140)
•
passing signs
•
exclusion signs
See Fig. 6.23 for currently recognized USA signs
and
Fig. 6.24. for Canadian signs.
When a traffic sign is recognized by the system, an
image representing it appears in the instrument
panel. See
Fig. 6.25. The ICU displays up to two
traffic signs at a time. If more than two signs are
recognized by the system, the most safety critical
signs are displayed.
