How does ABS work?
The maximum braking force
it is possible to transfer to the
carriageway depends, among
other things, on the road surface's
coefficient of friction. Gravel, ice
and snow, and water on the road,
have significantly poorer coeffi-
cients of friction than a dry, clean
asphalt road surface. The poorer
the road's coefficient of friction,
the longer the braking distance.
If the maximum braking force it is
possible to apply to the road is
exceeded when the rider
increases brake pressure, the
wheels will begin to lock and
directional stability is lost; a fall
threatens. Before this situation
can arise, ABS intervenes and
adapts the braking pressure to
the maximum braking force
it is possible to transfer so that
the wheels continue to turn and
driving stability is maintained
whatever the prevailing road
conditions.
What happens with bumps
in the road?
Corrugated road surfaces or
bumps in the road can cause the
tyres to temporarily lose contact
with the road surface and hence
the braking force it is possible to
apply to drop to zero. If the brakes
are applied in this situation, the
ABS must reduce the braking
pressure to ensure driving stability
when contact with the road sur-
face is restored. At this moment,
BMW Motorrad Integral ABS must
assume extremely low coeffi-
cients of friction (gravel, ice, snow)
so that the wheels turn in any con-
ceivable situation and thus the
stability of the motorcycle is
ensured. Once the actual circum-
stances are detected, the system
will set the brake pressure to the
optimum value.
