safety for braking in corners
as well. ABS Pro prevents the
wheels from locking even under
sharp braking. ABS Pro reduces
abrupt changes in steering
force, particularly in panic-
braking situations, counteracting
the vehicle's otherwise natural
but undesirable tendency to
straighten up.
ABS intervention
Technically speaking, depending
on the riding situation ABS Pro
adapts ABS intervention to the
motorcycle's bank angle. Signals
for rate of roll and rate of yaw
and lateral acceleration are used
to calculate bank angle. These
signals come from the angular
rate sensor, an integral compon-
ent of Dynamic Traction Control
DTC and Dynamic ESA.
As the motorcycle is heeled over
more and more as it banks into
a corner, an increasingly strict
limit is imposed on the brake-
pressure gradient for the start of
brake application. This slows the
build-up of brake pressure to a
corresponding degree. Addition-
ally, pressure modulation is more
uniform across the range of ABS
intervention.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and directional
stability combined with best-case
deceleration of the motorcycle,
even when cornering.
Dynamic Traction
Control (DTC)
How does DTC work?
The BMW Motorrad DTC com-
pares the speed of rotation of the
front wheel and the rear wheel.
The differential is used to com-
pute slip as a measure of the
reserves of stability available at
the rear wheel. If slip exceeds a
certain limit, the engine control
intervenes and adapts the engine
torque accordingly.
WARNING
Risky riding
Risk of accident despite DTC
Invariably, the rider bears re-
sponsibility for assessing road
and traffic conditions and ad-
opting his or her style of riding
accordingly.
Do not take risks that would
negate the additional safety
offered by this system.
What is the design
baseline for
BMW Motorrad DTC?
BMW Motorrad DTC is designed
as an assistant system for the
rider and for use on public roads.
