2019 MASERATI QUATTROPORTE steering

The icons that represent the status of
the ADAS systems remain displayed
even when you exit the "Driver Assist"
screen.
System Limitations Because of physical limits, in order to
properly operate, the system needs
good visibility (it might not work or
not properly operate in case of heavy rain, snow, wet roads, fog, direct sun
on the camera, etc.).
NOTE:
• 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 when
hands are actually on the steering
wheel (at least one).
• The sensors are not able to detect
the presence of the hands on the
steering wheel areas covered in
wood, plastic bezels or carbon
inserts (where present).
Sharp turns, slopes and change in
slopes, poor lane boundaries, as well
as construction areas and all the
scenario described in this paragraph
may challenge the system, therefore
be always ready to prevent any
unexpected behaviour of the car.
Damaged front bumper, windshield
replaced without proper technical
intervention may also lead to system
malfunction or system unavailability.
Other conditions such as fault, but not
explicitly indicated here may also prevent/interrupt the system
intervention.
WARNING!
If the driver fails to adapt his/her
driving style, Lane Keeping Assist
(LKA) can neither reduce the risk of an
accident nor override the laws of
physics. It cannot take into account
road, weather or traffic conditions.
Active LKA is only an aid. Driver is
always responsible for the distance to
the vehicle in front, for vehicle speed,
for braking in good time and for
staying in lane.
System in Fault When the LKA cannot properly
operate due to a fault of its
components or because the
windshield in front of the forward
facing camera is dirty, the amber light
and/or the corresponding message will
be displayed.Non-Driver Assist Page Driving

System is Faulty
The BSA system cannot properly
operate due to a fault of its
components, or because the area on
the rear bumper fascia where the
radar sensors are located is dirty. In
these cases the amber warning light
and the related message will be
displayed on the instrument cluster.
In these cases do not use the system
and have the vehicle inspected at an
Authorized Maserati Dealer .
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. Active Blind Spot Assist -
ABSA (optional, with ACC
only) ABSA system is only available on
vehicles equipped with ACC system
and represents an addition to the BSA
previously described (see chapter
"Blind Spot Assist - BSA" of this
section).
ABSA adds to the BSA the possibility in
certain circumstances to avoid and or
mitigate side collisions with vehicles
proceeding in the adjacent lanes by
changing the car's direction in order
to try to keep it inside the
detected/estimated lane. A steering
wheel vibration is used as further
feedback to warn the driver that the
lane change is not safe.
The main logic core is the front radar,
whereas the sense inputs are the
radars on the rear bumper fascia used
for sensing the presence of vehicle in
the blind spot areas and the forward
facing camera placed behind the
internal rear-view mirror that instead
is used for lane detection and
estimation.
ABSA is designed to help the driver to
avoid mitigate a collision. Torque and
vibration application is however available in the 37 - 112 mph (60 -
180 km/h) speed interval. All the speed
thresholds related to the BSA remain
still valid, since ABSA as mentioned is
BSA extension.
ABSA is intended as a “hands-on”
function meaning that the driver is
required to stay engaged in the
driving all the time with his/her hands
on the steering wheel, in case hands
are not on the steering wheel for a
certain time there cannot be any
steering torque application vibration
included.
System Availability ABSA is designed for an attentive
driver therefore the system is available
only when his/her hands are on the
steering wheel or with hands off for a
very limited amount of time. When
the system is enabled, it will trigger
cluster warning in case at least one
hand is not detected on the steering
wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, hands not on the
steering wheel detected for more than
a certain time.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

283

When ABSA is turned off from MTC+
"Controls" page, there will be no
visual or audible alerts from RCP
subsystem.
When ABSA is turned on with any
setting,RCP subsystem shall respond
with both visual and audible alerts
when a detected vehicle or object is
present. Whenever an audible alert is
requested, the radio (if on) is also
muted.
Right/left turn/hazard signal status is
ignored; the RCP status always
requests the chime.
System Temporarily
Unavailable The blind spot system will become
temporarily unavailable and the
instrument cluster display will show
the message “Blind Spot Alert
Temporarily Unavailable” when the
vehicle enters a radio quite zone
(example the areas around radio
telescopes).
The warning light on the outside
rear-view mirrors will be lit up and stay
lit until the vehicle exits the zone.
System Fault The ABSA system cannot properly
operate either due to a fault of its
components, or because the area on windshield where the forward-facing
camera is located or on the rear
bumper fascia where the radar sensors
are located is dirty. In these cases the
amber warning light and the related
message will be displayed on the
instrument cluster.
In these cases do not use the system
and have the vehicle inspected at an
Authorized Maserati Dealer .
Radar Device - Regulatory
Information The “Regulatory Information” for all

can be consulted by accessing the
“Services” section on the website
www.maserati.com.Highway Assist – HAS
(optional, with ACC only) The Highway Assist (HAS) is a level 2
Autonomy system (in reference to
NHTSA standards) that is designed to
aid the driver in the steering,
acceleration, and braking functions of
the vehicle.
HAS is designed to only function on
highways or limited access freeways.
HAS centers the vehicle by controlling
the EPS system based off of lane line
information from the forward-facing
camera and data from the front radar
sensor.
HAS combines ACC and LKA to
manage the steering and speed of the
vehicle under specific conditions. The
conditions to engage HAS are listed in
the next paragraph. If a lane line cross
is imminent, the steering wheel willDriving
5
284

vibrate and a graphic will display on
the instrument cluster.
WARNING!
• In case the vehicle approaches a
curve that is too tight in relation to
the current speed the system will
disengage, therefore the driver must
be prepared to take over control of
the vehicle immediately at any time.
To avoid this situation it is important
that the vehicle speed is not set
higher than the current speed limit
of the road.
• Highway Assist (HAS) is a hands-on
feature! You must keep your hands
on the steering wheel at all times.
The HAS system will disengage and
ACC will cancel if your hands are
removed from the steering wheels
for a set amount of time.
• HAS is intended for use only on
highways or limited access freeways
with a fully attentive driver. When
using HAS, hold the steering wheel
and be aware of surrounding traffic
and road conditions. Always be
prepared to immediately take over
control of the vehicle from the HAS
system. Failure to follow these instructions could result in serious
injury or death.
• The following list does not fully
represent all situations in which HAS
may not function as intended. Do
NOT solely rely on the HAS system
to control the vehicle. It is the
driver’s responsibility to stay alert
and safely control the vehicle at all
times.
• If the windshield is replaced, you
must have the forward-facing
camera remounted and aligned by
an Authorized Maserati Dealer.
Many factors can impact the
performance
of HAS
causing the
system to be unable to function as
intended. These include (but are not
limited to):
• Narrow, winding or curvy roads.
• Poor visibility (due to heavy rain,
snow, fog, etc.).
• Bright light (oncoming headlights or
direct sunlight) or shadows.
• Damage or obstruction caused by
mud, ice, snow, etc.
• A damaged or misaligned bumper.
• Interference from other equipment
that generates electromagnetic
waves. • Wet roads, roads covered or partially
covered by snow.
• Construction zones.
HAS Operation With ACC set (see “Adaptive Cruise
Crontrol – ACC” in this section), HAS
system activates by simply pressing the
button on the steering wheel.
Once the conditions are met, HAS will
engage.
CAUTION!
The Highway Assist (HAS) system may
take up to 5 seconds to engage once
all conditions are met.
The conditions for HAS to engage are
as
follows:
• HAS must be turned on or enabled.
NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• The vehicle must be on the highway
or limited access freeway.
• Adaptive Cruise Control (ACC) must
be engaged.
• Left and right visible lane lines.Driving
5
285

• Vehicle speed must be between 0 to
90 mph (0 and 145 km/h).
• No faults in the forward facing
camera, radar, EPS, or MTC+.
• Lane width between 3 to 4.6 yd (2.8
and 4.2 m).
• Turn signal not activated.
• No faults related to this system.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated
(with ACC engaged) 0 (0)
Engaged/activated
(with ACC not
engaged) 18 (30)
Maximum 90 (145)
• If set above the maximum speed,
HAS will not function after the
vehicle speed will reach the
maximum speed.
• If set below the maximum speed and
the ACC target speed is increased,
HAS will function up to the
maximum speed and then the system
will turn off automatically.
• When the ACC target speed is reduce
and speed is lower than the maximum speed, the system will start
automatically.
• If the ACC target speed is set under
the maximum speed, HAS is active
and vehicle speed increases above
the maximum speed due to slope,
HAS will continue to function.
HAS Monitoring on Instrument
Cluster HAS and the other ADAS systems
conditions can be monitored on
instrument cluster display by accessing
the “Driver Assist” page with the
buttons on the steering wheel (see
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
The
symbol in grey indicates that
the HAS system is active, but not
engaged and is shown at the centre of
the TFT display when the “Driver
Assist” page is displayed. When exiting
the "Driver Assist" page, on TFT
display top left corner, the
grey
symbol will appear in the multiple
light of active ADAS systems. In addition to these symbols, on the
TFT top and bottom edge a coloured
glow may appear (further referred to
as "attention level colour"). Attention
level colour together with the outline
of the symbol
represent a further
indication of the system status. Driver Assist Page
Non-Driver Assist PageDriving
5
286

When exiting the “Driver Assist” page,
the attention level colour will always
be displayed until the system is
disabled by pressing the
button on
the steering wheel.
The HAS system uses sensors in the
steering wheel outer crown to detect
if the driver’s hands are on the
steering wheel. If the driver’s hands
are not detected on the steering wheel, the instrument cluster will
display a series of warnings to alert
the driver to return their hands to the
steering wheel. There will also be
audible chimes. After a set amount of
time, HAS will cancel if the driver’s
hands are not returned to the steering
wheel.
When the system does not sense the
hands on the steering wheel for a few
seconds (3 – 5 seconds) or more (up to
10 seconds), it tries to draw the
attention of the driver by showing,
even when the display is not in the
"Driver Assist" page, the
symbol
with the figure of the hands in the
centre of the display. According to
such time frames, the system will
change the attention level colour,
silence the audio in the vehicle (if it is
active) and emit audible chimes to
invite the driver to take the control of
the vehicle again. This is the only way
to reengage the system.
Hands Detection on Steering
Wheel The sensors in the steering wheel
outer crown are able to detect the
presence of the hands on the steering
wheel. In order to be able to use the HAS
system, place your hands around the
steering wheel outer crown.
NOTE:
• The sensors are not able to detect
the presence of the hands on the
steering wheel areas covered in
wood, plastic bezels or carbon
inserts (where present).
HAS is deactivated if the steering
wheel is no longer being touched.
System Statuses The active status of the HAS system is
indicated by the green attention level
colour which is maintained even if the
driver releases his/her grip from the
steering wheel up to 3 seconds.
The yellow attention level colour
appears when the driver removes
his/her hands from the steering wheelDriver Assist Page
Non-Driver Assist Page Driving

for 3 to 5 seconds and the symbol
with the figure of the hands will
occupy the whole central area of the
display.
The red attention level colour appears
when the driver releases his/her grip
from the steering wheel for 5 and up
to 10 seconds: in this case a single
audible chime is repeated until he/she will take the control of the vehicle
again.
The red attention level colour remains
even when the steering wheel is
released for more than 8 to 10
seconds. In this case, if you are
travelling at a speed above 25 mph
(40 km/h) a sequences of 3 audible
chimes will be emitted after 8 seconds and a message will inform the driver
that the HAS system has been
disengaged, instructing him/her to grip
the steering wheel again. The same
will happen after 10 seconds if you
travel at a speed below 25 mph
(40 km/h). Then the
symbol on TFT
display will become grey.
If the driver keeps his/her hands away
from the steering wheel (for more
than 8 to 10 seconds), also the ACC
system is deactivated (
white ACC
symbol on the display) and will have to
be reset. The aid of LKA system will be
disabled as well. In these cases the
display will not show the attention
level colour anymore and the vehicle
will be controlled by the driver only.
