Traffic Sign Display With Speed Limit
Emphasis
Traffic sign display with speed limit emphasis
displays a red glow around a displayed speed limit
sign if the current vehicle speed exceeds, by a set
threshold, the detected speed limit.
Traffic Sign Display With Warnings
Traffic sign display with warnings builds on speed
limit emphasis. In addition to the red glow around
speed limit signs, the following warnings are added:
•
a pop-up notice window that tells the driver to
slow down.
•
a pop-up warning window that tells the driver
to slow down, shown in Fig. 6.26.
•
an audible excessive speed warning
•
a pop-up caution window accompanied by an
audible warning that tells the driver not to pass
These warnings are triggered by the vehicle speed
exceeding the detected speed limit by a set threshold
for a minimum amount of time. The driver must
acknowledge the visual warnings to dismiss them.
Active Speed Intervention
If the vehicle speed exceeds the detected speed limit
by more than a set amount for a minimum duration,
active speed intervention may, if equipped,
temporarily limit engine torque, adjust the cruise
control speed, or cancel cruise control to slow the
vehicle.
Active speed intervention displays a pop-up warning
window when any of these actions are taken. The
pop-up warning window about limiting the engine’s
torque is shown in
Fig. 6.27. The driver must
acknowledge these warnings to dismiss them.
