Adaptive ESP
Please note:
Brake Assist (BAS)
Start-Off Assist
Acceleration Skid Control (ASR)
At the first signs of wheelspin,
i.e. when one of the driven wheels
suddenly starts to rotate faster,
Acceleration Skid Control reduces
engine power and also intervenes in
the braking system. This prevents
prolonged wheelspin and sideways
drift when accelerating or pulling
away, meaning improved traction
and safety, particularly in slippery
conditions or on surfaces with
uneven levels of grip.
This enhanced version of our
Adaptive ESP can only act within
the laws of physics and is therefore
unable to prevent skidding caused
by aquaplaning, for example.
If the driver exceeds these limits,
Adaptive ESP will not enable an
accident to be avoided.
In tests carried out in the driving
simulator, our research engineers
established that drivers generally
don’t apply the brakes vigorously
enough during emergency braking.
This finding led them to develop
the system known as Brake Assist
(BAS). Brake Assist can detect an
emergency braking situation from
the speed at which the brake pedal is
depressed, then increase the braking
pressure automatically, with the anti-
lock braking system (ABS) preventing
the wheels from locking.
Integrated into the ESP system
and fitted as standard on automatic
models, Start-Off Assist allows hill
starts to be performed with ease.
After the brake pedal is released,
braking pressure is maintained for
approximately two seconds, allowing
the driver to move their foot from
the brake pedal to the accelerator
without having to worry about the
vehicle starting to roll back. Start-Off
Assist is activated on uphill gradients
of approx. 4% or steeper. It is not
activated when pulling away on the
flat or on a downhill slope.
Electronic Stability Programme
(ESP) ensures load levels are
now also taken into account in
interventions. It helps the driver to
deal with certain hazardous driving
situations, such as an imminent
risk of skidding, by actively applying
the brakes to one or more wheels
and adjusting the engine output as
required. As well as aiding directional
stability, Adaptive ESP combines
the functions of the anti-lock braking
system (ABS), Acceleration Skid
Control (ASR), electronic brake force
distribution (EBD), Brake Assist (BAS)
and the optional Start-Off Assist. As
an option, Adaptive ESP is available
with Trailer Stability Assist, which
further enhances safety when towing.
