Forward Collision Warning
– FCW
The Forward Collision Warning (FCW)
system with braking action uses the
same parts already described for
Adaptive Cruise Control (ACC) for
sensing vehicle ahead (hereinafter
“target vehicle”) as well as part of the
warnings/messages on system
condition and activation status.
Full performance can be reached only
when both the sensing parts have
detected a vehicle or, if the car is
equipped with Pedestrian Emergency
Braking (PEB) system, also a
pedestrian.
The difference between full and
reduced performance is not visible for
the driver.
Pedestrian Emergency Braking
(PEB) System (if equipped)
The Pedestrian Emergency Braking
(PEB) is a sub-system of FCW and it
provides the driver with audible
warnings, visual warnings on the
instrument cluster display, and may
apply automatic braking when it
detect a potential frontal collision with
a pedestrian.
WARNING!
Pedestrian Emergency Braking (PEB) is
not intended to avoid a collision on its
own, nor can PEB detect every type of
potential collision with pedestrian.
The driver has the responsibility to
avoid a collision by controlling the
vehicle via braking and steering.
Failure to follow this warning could
lead to serious injury or death.
FCW Operation
The FCW provides audible and visual
warnings when a potential collision is
detected. Brake jerk and limited
braking may also be applied
depending on the specific scenario.
FCW monitors the information from
the forward looking radar sensor as
well as the Electronic Brake Controller
(EBC), to calculate the probability of a
forward collision. When the system
determines that a forward collision is
probable, the driver will be provided
with audible and visual warnings and
may provide a warning brake
actuation. If the driver does not take
actuation based upon these
progressive warnings, then the system
will provide a limited level of active
braking to help slow down the vehicle
and mitigate the potential forward
collision. If the driver reacts to the
warnings by braking and the system
determines that the driver intends to
avoid the collision by braking but has
not applied sufficient brake force, the
