Traction Control (Asc/Dtc) - BMW CE 04 Rider's Manual

in the range of the ABS control
is more uniform.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and riding
stability with the best possible
deceleration, even in curves.
TRACTION CONTROL (ASC/
DTC)
How does traction control
work?
Traction Control is available in
two versions
Without taking the angle into
account: Automatic Stability
Control Automatic Stability
Control ASC
ASC is a rudimentary function
intended to prevent falls.
With taking the angle into
account: Dynamic Traction
Control DTC
The additional inclined posi-
tion and acceleration informa-
tion enables the DTC to make
more precise and comfortable
adjustments.
The traction control compares
the wheel centrifugal velocities
of the front and rear wheels.
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.
The BMW Motorrad ASC/DTC
is designed as an assistance
system for the rider and for
riding on public roads. The ex-
tent to which the rider affects
ASC/DTC control can be con-
siderable (weight shifts when
cornering, loose luggage on the
motorcycle), especially when
approaching the limits imposed
by the laws of physics.
WARNING
Risky riding style
Accident hazard despite ASC/
DTC
The rider is always respon-
sible for adapting his/her
driving style.
Do not reduce the system's
extra safety margin with
careless riding or unneces-
sary risks.
Special situations
As the lean angle increases,
the capacity to accelerate is
also increasingly limited by the
laws of physics. This can result
in reduced acceleration when
coming out of very tight curves.
