Porsche Stability Management (PSM).
PSM is an automatic control system
that stabilises the vehicle at the limits of
dynamic driving performance. Sensors
continuously monitor driving direction,
speed, yaw velocit y and lateral accelera -
tion. Using this information, PSM com -
putes the actual direction of motion. If
this direction deviates from the desired
course, PSM can, for example, initiate
braking interventions targeted at individual
wheels in order to stabilise the vehicle.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the ABD (automatic brake
differential) and ASR (antislip regulation)
functions.
For an even more involving driving
experience, you always have the option
to deactivate PSM. It is automatically
reactivated, for your safet y, only if you brake harder and either of the front
wheels (in SPORT PLUS mode, both
of the front wheels) requires ABS
assistance.
PSM comes with t wo additional
functions: precharging of the brake
system, enabling maximum braking
power to be achieved much sooner;
and brake assist, for maximum
deceleration in a critical situation.
Porsche Dynamic Chassis Control
(PDCC) including Porsche Torque
Vectoring Plus (PTV Plus).
PDCC is available as an option for the
Panamera GTS. This is an active anti-roll
system that anticipates and significantly
reduces lateral body movement during
cornering manoeuvres. In addition, it
minimises the lateral instability of the vehicle on uneven ground. The effect is
achieved with the aid of active anti-roll
bars on the front and rear axles which
respond to the current steering angle
and lateral acceleration by producing a
stabilising force that precisely negates
the roll of the body.
PT V Plus combined with PDCC is a
system that actively enhances vehicle
dynamics and stabilit y. Operating in con -
junction with an electronically regulated
rear differential lock, it works by varying
the torque distribution to the rear
wheels. To be more precise, this means
that when the car is driven assertively
into a corner, moderate brake pressure
is applied to the inside rear wheel.
Consequently, a greater amount of drive
force is distributed to the outside rear
wheel, inducing an additional rotational
pulse (yaw movement) around the vehi -
cle’s vertical axis. This results in a direct
and sport y steering action as the car enters the corner. At low and medium
vehicle speeds, PT V Plus significantly
increases agilit y and steering precision.
At high speeds and when accelerating out
of corners, the electronically regulated
rear dif ferential lock ensures greater
driving stabilit y. It also serves to improve
traction at the rear wheels on road sur -
faces with varying levels of grip, in the
wet and on snow.
For the driver, this means remarkable
lateral vehicle stabilit y, optimum traction
as well as a high degree of agilit y at
every speed with precise steering and
stable load transfer characteristics. In
short, it offers pure driving pleasure.
