Opel Corsa: Driver alert / Driver drowsiness detection
The system monitors the driver's level
of vigilance at speeds above
65 km/h. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings.
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a
message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent
of the driver's level of vigilance.
The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or
the speed remains below 65 km/h for
a few minutes.
The driver gets notified by a pop-up
reminder symbol in the Driver
Information Centre simultaneously
with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 65 km/h...
In the following situations, the system
may not operate properly or even not
operate at all:
poor visibility caused by
inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc...
Other information:
The front-rear parking assist
measures the distance between the
vehicle and obstacles in front and behind the vehicle. It informs and
warns the driver by giving acoustic
signals and display indication.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency...
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals...
