A central microcomputer analyzes the collected data
and triggers a response to keep the vehicle on
course when an unstable condition is detected.
When the system detects that the vehicle is at risk of
over-steering or under-steering, it applies individual
tractor wheel end brakes and trailer brakes and/or
cuts power to reduce the likelihood of a drift-out or
jackknife.
If the acceleration sensor detects the vehicle is at
risk of rolling over, the roll stability control system
within the ESC automatically reduces power and
applies the brakes.
Yaw control is not active below approximately 6 mph
(10 km/h). Roll stability control is not active below
approximately 12 mph (20 km/h). At higher speeds,
ESC operates automatically; the driver does not
monitor or activate the system.
The driver has full control over the vehicle until the
system detects a potential risk and intervenes
accordingly.
The ESC telltale, as shown in
Fig. 7.12, appears on
the driver display when ESC intervenes and when
ESC is unavailable due to a fault. The ESC telltale
flashes when an ESC event is actively occurring and
is solidly illuminated when ESC is unavailable due to
a fault.
It is normal for the ESC telltale to illuminate shortly
after a curve, lane change, or other driving maneuver
that results in ESC detecting a rollover-risk.
SafetyDirect® by Bendix
WARNING
SafetyDirect by Bendix is solely intended as a
support for a conscientious professional driver.
IMPORTANT: In order for the forward facing
camera to operate properly, the windshield area
in front of the camera must be clean,
unobstructed, and not be damaged in any way.
SafetyDirect by Bendix is a fleet management
system that automatically records ten to twenty
seconds of video during a safety event and delivers it
and other vehicle safety data wirelessly and in real
time to the Bendix SafetyDirect portal.
Bendix Forward Facing Camera
If equipped, the SafetyDirect system uses the
telematics systems of the vehicle and a Bendix 5G
forward facing video camera, shown in
Fig. 7.13.
The Bendix camera records in color and can capture
high-quality video in low light conditions.
Driver Facing Camera
If equipped with a driver facing camera, the
SafetyDirect system also records ten to twenty
seconds of driver behavior during an event.
The Bendix SafetyDirect Portal
If the vehicle is equipped with the SafetyDirect
system, data is sent from the vehicle’s safety
systems to the portal. The portal presents each
driver’s behavior in a ’miles between events’ format
with the following events recognized:
•
lane departure warning
•
excessive lane departure warning
•
lane change without turn signal
•
loss of video tracking
