Limited Slip Differential (Lsd) ( ) - Maserati GranTurismo 2024 Owner's Manual

WARNING!
Many factors, such as vehicle loading,
road and off-road conditions, and
driving conditions, influence the chance
that wheel lift or rollover may occur.
ROM cannot prevent all wheel lift or
roll-overs, especially those that involve
leaving the roadway or striking objects
or other vehicles. The capabilities of a
ROM-equipped vehicle must never be
exploited in a reckless or dangerous
manner, which could jeopardize the
user's safety or the safety of others.
Auto Vehicle Hold (AVH) ( )
The Auto Vehicle Hold function is an
extension of the hill holder function
that offers more convenience and
extra safety and it works only with the
seatbelt buckled.
Operated via the ABS/ESC hydraulic
unit, it stops the vehicle from rolling
away accidentally when standing still or
setting off. When you brake your car to a
standstill position with a fast brake pedal
pressure, Auto Vehicle Hold retains the
last-applied braking pressure. AVH can
be activated also when brake is not
pressed in specific rollback scenario and
during ACC Stop&Go.
Releasing the brake, all four-wheel
brakes will stay on. If the ABS wheel
speed sensors detect any rolling, braking
force is automatically increased until the
car comes to a standstill again. The
vehicle will be held in standstill for up to
10 minutes by hydraulic braking after
which time the electric park brake will
engage and continue to hold the vehicle
in standstill.
As soon as you press the accelerator,
Auto Vehicle Hold reduces the braking
pressure.
Understanding the Vehicle
Limited Slip Differential
(LSD) ( )
Mechanical Limited Slip
Differential
The mechanical self-locking differential
is used to limit the wheelspin of the
internal wheel when accelerating out of
corners and to stabilize the rear axle
when braking.
Electronic Limited Slip
Differential
With the electronic self-locking
differential the lock percentage is not
fixed but varies progressively with a
continuous control from 0 - 100 %.
The locking percentage is managed by
electro-hydraulic actuators controlled by
an electronic control unit integrated in
the vehicle's dynamics control system.
On the basis of the information received
from the engine, transmission, steering,
and brake sensors it decides both when
and how much to lock the differential,
with very high actuation speeds (up to
100 ms).
All this makes it possible to obtain
and guarantee greater traction during
acceleration, as well as high precision,
stability and maneuverability when
entering corners.
When cornering, the electronic LSD can:
