2019 MASERATI QUATTROPORTE brake sensor

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, theDriving

providing limited autonomous braking
or additional brake support if the
driver is not braking adequately in the
event of a potential frontal collision.
In this state the system disables the
brake jerk.
Limited Operation and Service
Warning The messages indicating on display the
limited functionality or service at an
Authorized Maserati Dealer required
are the same as for the ACC system.
For further details, refer to “Adaptive
Cruise Control – ACC” in this section.
NOTE:
• The adjustment of the sensor could
be affected by strong shocks or light
collisions. This could affect the
system by reducing the systems
performance or could increase the
false positive rate. The adjustment of
the radar system has to be proved or
a new adjustment has to be
performed by an Authorized
Maserati Dealer .
• The radar system requires specific
feature to detect objects. The
detection could be disturbed/
reduced by environment influences,
for example by electrical field or the
object itself. Object with small radar reflection properties could not be
detected or detected late.
Radar Device - Regulatory
Information The “Regulatory Information” for all
the radio frequency and radar devices
can be consulted by accessing the
“Services” section on the website
www.maserati.com.
Lane Keeping Assist - LKA
(optional, with ACC only) This system was designed especially
for highway or freeway driving, to
reduce the risk that the vehicle, under
particular circumstances, accidentally
departs from the lane in use. When
this happens, graphic instructions on
instrument cluster display together
with steering torque application and
steering wheel vibration (depending
on the distance to the line) warn the
driver that the vehicle is going out of
the lane initiates a steering maneuver
to try to prevent the lane exit.
To detect lane lines, the system uses
the forward-facing camera behind the
rear-view mirror, which is the same
one used also by the lighting system
to manage the automatic high beams.
The logic core is in the front radar.
LKA system remembers the condition
it was in before turning off the
vehicle.
Refer to “MTC+ "Controls" Screen” in
section “Dashboard Instruments and
Controls” for further information.Driving

System sensitivity can be set to
“Early”, “Medium” (default mode) or
“Late”.
System strength can be set to "Low",
"Medium" (default mode) or "High".
NOTE:
The ABSA system will store the current
operating mode when the vehicle is
shut off. Each time the vehicle is
started, the previously-stored mode
will be recalled and used.
Meanings of Settings
When "Visual & Haptic" is selected
and of course ABSA is enabled, then
two following menus will be used by
the system.
• ABSA “Sensitivity": it tunes the
distance to the lane boundary where
the system will start to apply
steering torque. • ABSA “Strength": it tunes the
steering torque value to have a
stronger or weaker directional
correction/deviation.
Blind Spot Assist in "Visual & Haptic"
Mode
When the system is on and configured
“Visual & Haptic” then the ABSA is
enabled and to the conventional
visual warnings is added the steering
torque and vibration.
When operating in this mode, the
system will provide a visual alert in the
appropriate outside rear-view mirror
when it detects a vehicle or an object
in the detection areas monitored by its
sensors. In case of turn indicator
activation on the appropriate side, the
system will react with a torque on the
steering wheel to try to prevent the
lane change and therefore to
avoid/mitigate the collision. The
torque on the steering is applied
when the car is very close to the lane
boundary as a further feedback to
warn the driver of the unsafe
maneuver.
NOTE:
• The steering torque is not supplied if
the system is not able to estimate a
lane and if the turn indicator from
the appropriate side is not inserted. • The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
WARNING!
• Risk of accident despite steering
torque application of Active Blind
Spot Assist (ABSA).
• A course-correcting steering torque
application cannot always prevent a
collision.
• The driver is always required to
steer, brake or accelerate themself,
especially if ABSA warns or makes a
course correcting steer intervention.
• Always maintain a safe distance at
the sides.
• Steering torque application may be
interrupted at any time by counter
steering by the driver.
RCP - Rear Cross Path
Operation RCP operation is the same as described
in chapter "Blind Spot Assist - BSA".Driving

• Press the HAS enable button on
the steering wheel.
• Begin steering manually.
• Press brake pedal.
• Turn off ACC.
• Unbuckle the driver’s seat belt.
• Press ACC Gap button for two
seconds to enable CC system.
• Shift out of the (D) Drive gear.
• Enter an Autonomous Emergency
Braking (AEB) event (See chapter
"Forward Collision Warning - FCW"
in this section).
• Turn signal activated.
System Cancellation The HAS system will cancel (without
driver intervention) if either of the
following actions occur:
• Curve that is too tight.
• When leaving the grip of the hands
on the steering wheel.
• Vehicle exits the highway or limited
access freeway.
• Lane line markers aren’t detected by
the forward facing camera.
• Any ADAS system faults.
• ACC cancellation.
• Vehicle speed exceeds the maximum
limit. • Lateral accelerations exceeds the
limits.
NOTE:
• When HAS cancels, the
symbol
will turn red then grey.
• The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
System Limitations HAS is unable to guide the vehicle
when the following conditions occur.
• Lane markings are not clear or
visibility is poor (i.e. heavy rain,
snow, fog, etc.).
• Obstructed, covered or damaged
forward-facing camera or sensor.
• When driving on hills or sharp
curves.
• When approaching toll booths.
• When the highway entrance or exit
is wider than 20 ft (6 meters).
• Bright light (ex. direct sunlight or
glare) facing the forward camera. WARNING!
Many unforeseen conditions can occur
that can affect the performance of
Highway Assist (HAS). Always keep
this in mind and drive attentively. It is
the drivers responsibility to keep
control of the vehicle at all times.
