Anti-Lock Brake
System
How does the ABS work?
The maximum braking force that
can be transferred to the road
surface is partially dependent on
the friction coefficient of the road
surface. Gravel, ice, snow and
wet roads offer a considerably
poorer friction coefficient than a
dry, clean asphalt surface. The
poorer the friction coefficient of
the road surface is, the longer
the braking distance will be.
If the maximum transferable
brake force is exceeded when
the driver increases the brake
pressure, the wheels begin
to lock and driving stability is
lost. A fall can occur. Before
this situation can occur, ABS
intervenes and adapts brake
pressure to the maximum
transferable brake force, so the
wheels continue to turn and
driving stability is maintained
irrespective of the condition of
the road surface.
What happens when
rough roads are
encountered?
Bumpy or rough roads can briefly
lead to a loss of contact between
the tires and the road surface,
until the transferable braking
force is reduced to zero. If brak-
ing is carried out in this situa-
tion, ABS must reduce the brake
pressure to ensure driving stabil-
ity when restoring contact to the
road. At this point in time, the
ABS must assume extremely low
friction coefficients (gravel, ice,
snow) so that the running wheels
turn in every imaginable case and
the driving stability is ensured.
After detecting the actual con-
ditions, the system adjusts the
optimum brake pressure.
Lifting off rear wheel
Even during severe braking, a
high level of tire grip can mean
that the front wheel does not
lock up until very late, if at all.
Consequently, ABS does not in-
tervene until very late, if at all.
Under these circumstances the
rear wheel can lift off the ground,
and the outcome can be a high-
siding situation in which the mo-
torcycle can flip over.
