2010 PORSCHE PANAMERA traction control

· 70 ·· 71 ·
A Porsche holds the road well, its
handling is sport y and precise –
but you’ve known this for a long
time.
What you might not know is
that, with the optional Porsche
Dynamic Chassis Control (PDCC)
with Porsche Torque Vectoring
Plus (PT V Plus), road holding can
be even further improved in all the Panamera models for even more
dynamic per formance and
increased comfort.
PDCC is an active anti-roll system
that anticipates and significantly
reduces lateral body movement
during cornering manoeuvres. In
addition, it minimises the lateral
instabilit y of the vehicle on uneven
ground. The ef fect 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 conjunction with an
electronically regulated rear dif
-
ferential lock, it works by varying
the torque distribution to the rear
wheels. As a function of steering
angle and steering speed,
accel -
erator pedal position, yaw rate and

vehicle speed, PT V Plus is able
to improve steering response and
steering precision by specific
braking of the right or left rear
wheel.
To be more precise, this means
that when the car is driven asser -
tively 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 vehicle’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 acceler -
ating out of corners, the elec -
tron
ically regulated rear differential
lock ensures greater driving
stabilit y. It also serves to improve
traction at the rear wheels on
road surfaces with varying levels
of grip as well as on snow and ice.
For the driver, this means remark -
able stabilit y and easier handling,
optimum traction, and greater
agilit y at every speed with precise
steering and stable load transfer
characteristics. The result is
a high level of driving pleasure.

As standard, all Panamera models
are equipped with enhanced
Porsche Stabilit y Management
(PSM), which maintains stabilit y
even at the limits of dynamic
driving per formance. Sensors
continuously monitor the direction,
speed, yaw velocit y and lateral
acceleration of the car. Using
this information, PSM is able to calculate the actual direction of
travel at any given moment. If

the car be gins to oversteer or
understeer, PSM applies selective
braking
on individual wheels to
restore
stabilit y.
Under acceleration on wet or low-
grip road surfaces, PSM improves
traction – and agilit y – using the
automatic brake dif ferential (ABD), antislip regulation (ASR) and
engine drag torque control (MSR).
When ‘SPORT PLUS’ mode is
selected
on the optional Sport
Chrono Package Plus (p. 74)
or Sport
Chrono Package Turbo
(p. 76), the PSM intervention
threshold is raised to allow a
sportier driving st yle.
For an even more dynamic expe-
rience, 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.
ABS and ABD, however, remain
active at all times.
For an even higher level of active
safet y, the enhanced PSM includes
t wo additional functions: pre -
charging of the brake system, and
brake assist. If you suddenly release the accel
-
erator pedal, PSM detects the
release of the throt tle and auto -
matically readies the braking
system. This precharging of the
braking system builds up a small
amount of pressure so that the
brake pads are already in light
contact with the brake discs. If
you actually need to apply the
brakes, maximum braking power
is therefore achieved much
sooner, which reduces the stop -
ping distance even further. Brake
assist, on the other hand, is
able to interpret a panic braking situation from a rapid increase in
brake pressure and acts to ensure
that the amount of brake pressure
required for maximum decelera
-
tion is immediately available.
PSM therefore of fers a high level
of driving stabilit y and safet y com -
bined with extraordinary agil
it y.
In line with the Porsche philosophy.
Even a Porsche has limits to its dynamic performance.
