Dynamic Traction Control (Dtc) - BMW M 1000 RR 2021 Rider's Manual

ABS Pro
ABS Pro increases safety,
particularly when braking
in bends. ABS Pro prevents
the wheels from locking
even under sharp braking.
ABS Pro reduces abrupt
changes in steering force,
particularly in shock-braking
situations, counteracting the
vehicle's otherwise natural
but undesirable tendency to
straighten up.
ABS intervention
Technically speaking, depend-
ing on the riding situation
ABS Pro adapts ABS inter-
vention to the motorcycle's
bank angle. Signals for rate
of roll and rate of yaw and
lateral acceleration are used
to calculate bank angle. They
come from the angular rate
sensor, an integral component
of Dynamic Traction Control
DTC.
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. Addi-
tionally, 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 direc-
tional stability combined with
best-case deceleration of the
motorcycle, even when corner-
ing.
ABS Pro is activated in
the
RAIN
riding modes. In
DYNAMIC
the Dynamic Pro riding mode,
ABS Pro can be parametrised
to suit the rider's individual
needs and preferences.
DYNAMIC TRACTION CON-
TROL (DTC)
How does Dynamic Traction
Control work?
DTC takes the vehicle tilt into
accounts, conveniently controls
it and is useful for improving
lap times on the racetrack.
The Dynamic Traction Control
system compares the speed
of rotation at the circumfer-
ences of the front wheel and
the rear wheel. The differen-
tial is used to compute slip as
a measure of the reserves of
stability available at the rear
wheel. If slip exceeds a certain
limit, the engine management
