Information on BMW Motorrad Integral ABS
How does ABS work?
The maximum braking force
which can be transferred to
the road surface is partially
dependent on the coefficient
of friction of the road surface.
Gravel, ice, snow and wet road
surfaces offer a considerably
poorer coefficient of friction
than a dry, clean layer of
asphalt. The lower the coeffi-
cient of friction of the road
surface is, the longer the
braking distance will be.
If the maximum transferrable
braking force is exceeded
when the driver increases the
brake pressure applied, the
wheels begin to lock and
the driving stability is lost,
resulting in a danger of falling.
Before this situation occurs,
the ABS intervenes and
adjusts the brake pressure
to the maximum transferrable
braking force. As a result,
the wheels continue to turn
and the driving stability is
maintained regardless of the
road surface condition.
What happens on uneven
road surfaces?
Wavy ground or uneven road
surfaces can briefly result in a
loss of contact between the
tire and the road surface, and
the transferrable braking force
decreases to zero. If the
brakes are applied in this
situation, the ABS must
reduce the brake pressure to
ensure driving stability when
contact with the road surface
is restored. At this point in time
the BMW Motorrad Integral
ABS must assume extremely
low coefficients of friction
(gravel, ice or snow) so that
the wheels turn in every
imaginable case and the
driving stability is ensured.
After the actual conditions are
detected, the system adjusts
the brake pressure to the
optimum value.
What must be observed
during driving safety
training?
Compared to normal braking,
braking during which the ABS
must intervene in a regulating
manner
requires a consider-
