ABS control
From a technical standpoint,
ABS Pro adjusts the ABS con-
trol to the angle of inclination of
the motorcycle in dependence
on the respective riding situation.
Signals for the roll and yaw rate
and the lateral acceleration are
used to determine the inclina-
tion of the motorcycle. The sig-
nals come from the angular rate
sensor, which is already used for
Dynamic Traction Control DTC
and for Dynamic ESA.
With an increasing angle, the
brake pressure gradient is in-
creasingly limited at the start of
braking. This results in a slower
pressure buildup. In addition, the
pressure modulation in the range
of the ABS control is more uni-
form.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and riding sta-
bility with the best possible de-
celeration, even in curves.
NOTICE
ABS Pro is activated in the
RAIN
,
ROAD
and
DYNAMIC
riding
modes. In the Dynamic Pro
riding mode, ABS Pro can be set
individually.
Dynamic traction
control (DTC)
How does traction control
work?
The traction control compares
the wheel circumferential veloc-
ities of the front and rear wheel.
The slip, and with it the stabil-
ity reserves at the rear wheel,
are determined from the speed
difference. The engine control
adapts the engine torque when
the slip limit is exceeded.
BMW Motorrad DTC is designed
as an assistance system for the
rider and for riding on public
roads. The extent to which the
rider affects DTC control can be
considerable (weight shifts when
cornering, loose luggage on the
motorcycle), especially when ap-
proaching the limits imposed by
the laws of physics.
The system is not optimized for
the special conditions encoun-
tered under the extreme condi-
tions of competitive off-road and
race-track use. BMW Motorrad
DTC can be switched off in such
instances.
